The reason of this +appears sufficiently from the treatise itself. Its business is to show +that there is pure practical reason, and for this purpose it +criticizes the entire practical faculty of reason. If it succeeds in +this, it has no need to criticize the pure faculty itself in order +to see whether reason in making such a claim does not presumptuously +overstep itself (as is the case with the speculative reason). For +if, as pure reason, it is actually practical, it proves its own +reality and that of its concepts by fact, and all disputation +against the possibility of its being real is futile. + +With this faculty, transcendental freedom is also established; +freedom, namely, in that absolute sense in which speculative reason +required it in its use of the concept of causality in order to +escape the antinomy into which it inevitably falls, when in the +chain of cause and effect it tries to think the unconditioned. +Speculative reason could only exhibit this concept (of freedom) +problematically as not impossible to thought, without assuring it +any objective reality, and merely lest the supposed impossibility of +what it must at least allow to be thinkable should endanger its very +being and plunge it into an abyss of scepticism. + +Inasmuch as the reality of the concept of freedom is proved by an +apodeictic law of practical reason, it is the keystone of the whole +system of pure reason, even the speculative, and all other concepts +(those of God and immortality) which, as being mere ideas, remain in +it unsupported, now attach themselves to this concept, and by it +obtain consistence and objective reality; that is to say, their +possibility is proved by the fact that freedom actually exists, for +this idea is revealed by the moral law. + +Freedom, however, is the only one of all the ideas of the +speculative reason of which we know the possibility a priori (without, +however, understanding it), because it is the condition of the moral +law which we know. * The ideas of God and immortality, however, are +not conditions of the moral law, but only conditions of the necessary +object of a will determined by this law; that is to say, conditions of +the practical use of our pure reason. Hence, with respect to these +ideas, we cannot affirm that we know and understand, I will not say +the actuality, but even the possibility of them. However they are +the conditions of the application of the morally determined will to +its object, which is given to it a priori, viz., the summum bonum. +Consequently in this practical point of view their possibility must be +assumed, although we cannot theoretically know and understand it. To +justify this assumption it is sufficient, in a practical point of +view, that they contain no intrinsic impossibility (contradiction). +Here we have what, as far as speculative reason is concerned, is a +merely subjective principle of assent, which, however, is +objectively valid for a reason equally pure but practical, and this +principle, by means of the concept of freedom, assures objective +reality and authority to the ideas of God and immortality. Nay, +there is a subjective necessity (a need of pure reason) to assume +them. Nevertheless the theoretical knowledge of reason is not hereby +enlarged, but only the possibility is given, which heretofore was +merely a problem and now becomes assertion, and thus the practical use +of reason is connected with the elements of theoretical reason. And +this need is not a merely hypothetical one for the arbitrary +purposes of speculation, that we must assume something if we wish in +speculation to carry reason to its utmost limits, but it is a need +which has the force of law to assume something without which that +cannot be which we must inevitably set before us as the aim of our +action. + + + + {PREFACE ^paragraph 5} + +* Lest any one should imagine that he finds an inconsistency here +when I call freedom the condition of the moral law, and hereafter +maintain in the treatise itself that the moral law is the condition +under which we can first become conscious of freedom, I will merely +remark that freedom is the ratio essendi of the moral law, while the +moral law is the ratio cognoscendi of freedom. For had not the moral +law been previously distinctly thought in our reason, we should +never consider ourselves justified in assuming such a thing as +freedom, although it be not contradictory. But were there no freedom +it would be impossible to trace the moral law in ourselves at all. + + + +It would certainly be more satisfactory to our speculative reason if +it could solve these problems for itself without this circuit and +preserve the solution for practical use as a thing to be referred +to, but in fact our faculty of speculation is not so well provided. +Those who boast of such high knowledge ought not to keep it back, +but to exhibit it publicly that it may be tested and appreciated. They +want to prove: very good, let them prove; and the critical +philosophy lays its arms at their feet as the victors. Quid statis? +Nolint. Atqui licet esse beatis. As they then do not in fact choose to +do so, probably because they cannot, we must take up these arms +again in order to seek in the mortal use of reason, and to base on +this, the notions of God, freedom, and immortality, the possibility of +which speculation cannot adequately prove. + +Here first is explained the enigma of the critical philosophy, viz.: +how we deny objective reality to the supersensible use of the +categories in speculation and yet admit this reality with respect to +the objects of pure practical reason. This must at first seem +inconsistent as long as this practical use is only nominally known. +But when, by a thorough analysis of it, one becomes aware that the +reality spoken of does not imply any theoretical determination of +the categories and extension of our knowledge to the supersensible; +but that what is meant is that in this respect an object belongs to +them, because either they are contained in the necessary determination +of the will a priori, or are inseparably connected with its object; +then this inconsistency disappears, because the use we make of these +concepts is different from what speculative reason requires. On the +other hand, there now appears an unexpected and very satisfactory +proof of the consistency of the speculative critical philosophy. For +whereas it insisted that the objects of experience as such, +including our own subject, have only the value of phenomena, while +at the same time things in themselves must be supposed as their basis, +so that not everything supersensible was to be regarded as a fiction +and its concept as empty; so now practical reason itself, without +any concert with the speculative, assures reality to a supersensible +object of the category of causality, viz., freedom, although (as +becomes a practical concept) only for practical use; and this +establishes on the evidence of a fact that which in the former case +could only be conceived. By this the strange but certain doctrine of +the speculative critical philosophy, that the thinking subject is to +itself in internal intuition only a phenomenon, obtains in the +critical examination of the practical reason its full confirmation, +and that so thoroughly that we should be compelled to adopt this +doctrine, even if the former had never proved it at all. * + + + + {PREFACE ^paragraph 10} + +* The union of causality as freedom with causality as rational +mechanism, the former established by the moral law, the latter by +the law of nature in the same subject, namely, man, is impossible, +unless we conceive him with reference to the former as a being in +himself, and with reference to the latter as a phenomenon- the +former in pure consciousness, the latter in empirical consciousness. +Otherwise reason inevitably contradicts itself. + + + +By this also I can understand why the most considerable objections +which I have as yet met with against the Critique turn about these two +points, namely, on the one side, the objective reality of the +categories as applied to noumena, which is in the theoretical +department of knowledge denied, in the practical affirmed; and on +the other side, the paradoxical demand to regard oneself qua subject +of freedom as a noumenon, and at the same time from the point of +view of physical nature as a phenomenon in one's own empirical +consciousness; for as long as one has formed no definite notions of +morality and freedom, one could not conjecture on the one side what +was intended to be the noumenon, the basis of the alleged +phenomenon, and on the other side it seemed doubtful whether it was at +all possible to form any notion of it, seeing that we had previously +assigned all the notions of the pure understanding in its +theoretical use exclusively to phenomena. Nothing but a detailed +criticism of the practical reason can remove all this +misapprehension and set in a clear light the consistency which +constitutes its greatest merit. + +So much by way of justification of the proceeding by which, in +this work, the notions and principles of pure speculative reason which +have already undergone their special critical examination are, now and +then, again subjected to examination. This would not in other cases be +in accordance with the systematic process by which a science is +established, since matters which have been decided ought only to be +cited and not again discussed. In this case, however, it was not +only allowable but necessary, because reason is here considered in +transition to a different use of these concepts from what it had +made of them before. Such a transition necessitates a comparison of +the old and the new usage, in order to distinguish well the new path +from the old one and, at the same time, to allow their connection to +be observed. Accordingly considerations of this kind, including +those which are once more directed to the concept of freedom in the +practical use of the pure reason, must not be regarded as an +interpolation serving only to fill up the gaps in the critical +system of speculative reason (for this is for its own purpose +complete), or like the props and buttresses which in a hastily +constructed building are often added afterwards; but as true members +which make the connexion of the system plain, and show us concepts, +here presented as real, which there could only be presented +problematically. This remark applies especially to the concept of +freedom, respecting which one cannot but observe with surprise that so +many boast of being able to understand it quite well and to explain +its possibility, while they regard it only psychologically, whereas if +they had studied it in a transcendental point of view, they must +have recognized that it is not only indispensable as a problematical +concept, in the complete use of speculative reason, but also quite +incomprehensible; and if they afterwards came to consider its +practical use, they must needs have come to the very mode of +determining the principles of this, to which they are now so loth to +assent. The concept of freedom is the stone of stumbling for all +empiricists, but at the same time the key to the loftiest practical +principles for critical moralists, who perceive by its means that they +must necessarily proceed by a rational method. For this reason I beg +the reader not to pass lightly over what is said of this concept at +the end of the Analytic. + +I must leave it to those who are acquainted with works of this +kind to judge whether such a system as that of the practical reason, +which is here developed from the critical examination of it, has +cost much or little trouble, especially in seeking not to miss the +true point of view from which the whole can be rightly sketched. It +presupposes, indeed, the Fundamental Principles of the Metaphysic of +Morals, but only in so far as this gives a preliminary acquaintance +with the principle of duty, and assigns and justifies a definite +formula thereof; in other respects it is independent. * It results +from the nature of this practical faculty itself that the complete +classification of all practical sciences cannot be added, as in the +critique of the speculative reason. For it is not possible to define +duties specially, as human duties, with a view to their +classification, until the subject of this definition (viz., man) is +known according to his actual nature, at least so far as is +necessary with respect to duty; this, however, does not belong to a +critical examination of the practical reason, the business of which is +only to assign in a complete manner the principles of its possibility, +extent, and limits, without special reference to human nature. The +classification then belongs to the system of science, not to the +system of criticism. + + {PREFACE ^paragraph 15} + + + +* A reviewer who wanted to find some fault with this work has hit +the truth better, perhaps, than he thought, when he says that no new +principle of morality is set forth in it, but only a new formula. +But who would think of introducing a new principle of all morality and +making himself as it were the first discoverer of it, just as if all +the world before him were ignorant what duty was or had been in +thorough-going error? But whoever knows of what importance to a +mathematician a formula is, which defines accurately what is to be +done to work a problem, will not think that a formula is insignificant +and useless which does the same for all duty in general. + + + +In the second part of the Analytic I have given, as I trust, a +sufficient answer to the objection of a truth-loving and acute +critic * of the Fundamental Principles of the Metaphysic of Morals- a +critic always worthy of respect- the objection, namely, that the +notion of good was not established before the moral principle, as he +thinks it ought to have been. *(2) I have also had regard to many of +the objections which have reached me from men who show that they have +at heart the discovery of the truth, and I shall continue to do so +(for those who have only their old system before their eyes, and who +have already settled what is to be approved or disapproved, do not +desire any explanation which might stand in the way of their own +private opinion.) + + + + {PREFACE ^paragraph 20} + +* [See Kant's "Das mag in der Theoric ricktig seyn," etc. Werke, +vol. vii, p. 182.] + +*(2) It might also have been objected to me that I have not first +defined the notion of the faculty of desire, or of the feeling of +Pleasure, although this reproach would be unfair, because this +definition might reasonably be presupposed as given in psychology. +However, the definition there given might be such as to found the +determination of the faculty of desire on the feeling of pleasure +(as is commonly done), and thus the supreme principle of practical +philosophy would be necessarily made empirical, which, however, +remains to be proved and in this critique is altogether refuted. It +will, therefore, give this definition here in such a manner as it +ought to be given, in order to leave this contested point open at +the beginning, as it should be. LIFE is the faculty a being has of +acting according to laws of the faculty of desire. The faculty of +DESIRE is the being's faculty of becoming by means of its ideas the +cause of the actual existence of the objects of these ideas. +PLEASURE is the idea of the agreement of the object, or the action +with the subjective conditions of life, i.e., with the faculty of +causality of an idea in respect of the actuality of its object (or +with the determination of the forces of the subject to action which +produces it). I have no further need for the purposes of this critique +of notions borrowed from psychology; the critique itself supplies +the rest. It is easily seen that the question whether the faculty of +desire is always based on pleasure, or whether under certain +conditions pleasure only follows the determination of desire, is by +this definition left undecided, for it is composed only of terms +belonging to the pure understanding, i.e., of categories which contain +nothing empirical. Such precaution is very desirable in all philosophy +and yet is often neglected; namely, not to prejudge questions by +adventuring definitions before the notion has been completely +analysed, which is often very late. It may be observed through the +whole course of the critical philosophy (of the theoretical as well as +the practical reason) that frequent opportunity offers of supplying +defects in the old dogmatic method of philosophy, and of correcting +errors which are not observed until we make such rational use of these +notions viewing them as a whole. + + + +When we have to study a particular faculty of the human mind in +its sources, its content, and its limits; then from the nature of +human knowledge we must begin with its parts, with an accurate and +complete exposition of them; complete, namely, so far as is possible +in the present state of our knowledge of its elements. But there is +another thing to be attended to which is of a more philosophical and +architectonic character, namely, to grasp correctly the idea of the +whole, and from thence to get a view of all those parts as mutually +related by the aid of pure reason, and by means of their derivation +from the concept of the whole. This is only possible through the +most intimate acquaintance with the system; and those who find the +first inquiry too troublesome, and do not think it worth their while +to attain such an acquaintance, cannot reach the second stage, namely, +the general view, which is a synthetical return to that which had +previously been given analytically. It is no wonder then if they +find inconsistencies everywhere, although the gaps which these +indicate are not in the system itself, but in their own incoherent +train of thought. + +I have no fear, as regards this treatise, of the reproach that I +wish to introduce a new language, since the sort of knowledge here +in question has itself somewhat of an everyday character. Nor even +in the case of the former critique could this reproach occur to anyone +who had thought it through and not merely turned over the leaves. To +invent new words where the language has no lack of expressions for +given notions is a childish effort to distinguish oneself from the +crowd, if not by new and true thoughts, yet by new patches on the +old garment. If, therefore, the readers of that work know any more +familiar expressions which are as suitable to the thought as those +seem to me to be, or if they think they can show the futility of these +thoughts themselves and hence that of the expression, they would, in +the first case, very much oblige me, for I only desire to be +understood: and, in the second case, they would deserve well of +philosophy. But, as long as these thoughts stand, I very much doubt +that suitable and yet more common expressions for them can be found. * + + {PREFACE ^paragraph 25} + + + +* I am more afraid in the present treatise of occasional +misconception in respect of some expressions which I have chosen +with the greatest care in order that the notion to which they point +may not be missed. Thus, in the table of categories of the Practical +reason under the title of Modality, the Permitted, and forbidden (in a +practical objective point of view, possible and impossible) have +almost the same meaning in common language as the next category, +duty and contrary to duty. Here, however, the former means what +coincides with, or contradicts, a merely possible practical precept +(for example, the solution of all problems of geometry and mechanics); +the latter, what is similarly related to a law actually present in the +reason; and this distinction is not quite foreign even to common +language, although somewhat unusual. For example, it is forbidden to +an orator, as such, to forge new words or constructions; in a +certain degree this is permitted to a poet; in neither case is there +any question of duty. For if anyone chooses to forfeit his +reputation as an orator, no one can prevent him. We have here only +to do with the distinction of imperatives into problematical, +assertorial, and apodeictic. Similarly in the note in which I have +pared the moral ideas of practical perfection in different +philosophical schools, I have distinguished the idea of wisdom from +that of holiness, although I have stated that essentially and +objectively they are the same. But in that place I understand by the +former only that wisdom to which man (the Stoic) lays claim; therefore +I take it subjectively as an attribute alleged to belong to man. +(Perhaps the expression virtue, with which also the Stoic made great show, +would better mark the characteristic of his school.) The expression of +a postulate of pure practical reason might give most occasion to +misapprehension in case the reader confounded it with the +signification of the postulates in pure mathematics, which carry +apodeictic certainty with them. These, however, postulate the +possibility of an action, the object of which has been previously +recognized a priori in theory as possible, and that with perfect +certainty. But the former postulates the possibility of an object +itself (God and the immortality of the soul) from apodeictic practical +laws, and therefore only for the purposes of a practical reason. +This certainty of the postulated possibility then is not at all +theoretic, and consequently not apodeictic; that is to say, it is +not a known necessity as regards the object, but a necessary +supposition as regards the subject, necessary for the obedience to its +objective but practical laws. It is, therefore, merely a necessary +hypothesis. I could find no better expression for this rational +necessity, which is subjective, but yet true and unconditional. + + + +In this manner, then, the a priori principles of two faculties of +the mind, the faculty of cognition and that of desire, would be +found and determined as to the conditions, extent, and limits of their +use, and thus a sure foundation be paid for a scientific system of +philosophy, both theoretic and practical. + +Nothing worse could happen to these labours than that anyone +should make the unexpected discovery that there neither is, nor can +be, any a priori knowledge at all. But there is no danger of this. +This would be the same thing as if one sought to prove by reason +that there is no reason. For we only say that we know something by +reason, when we are conscious that we could have known it, even if +it had not been given to us in experience; hence rational knowledge +and knowledge a priori are one and the same. It is a clear +contradiction to try to extract necessity from a principle of +experience (ex pumice aquam), and to try by this to give a judgement +true universality (without which there is no rational inference, not +even inference from analogy, which is at least a presumed universality +and objective necessity). To substitute subjective necessity, that is, +custom, for objective, which exists only in a priori judgements, is to +deny to reason the power of judging about the object, i.e., of knowing +it, and what belongs to it. It implies, for example, that we must +not say of something which often or always follows a certain +antecedent state that we can conclude from this to that (for this +would imply objective necessity and the notion of an a priori +connexion), but only that we may expect similar cases (just as animals +do), that is that we reject the notion of cause altogether as false +and a mere delusion. As to attempting to remedy this want of objective +and consequently universal validity by saying that we can see no +ground for attributing any other sort of knowledge to other rational +beings, if this reasoning were valid, our ignorance would do more +for the enlargement of our knowledge than all our meditation. For, +then, on this very ground that we have no knowledge of any other +rational beings besides man, we should have a right to suppose them to +be of the same nature as we know ourselves to be: that is, we should +really know them. I omit to mention that universal assent does not +prove the objective validity of a judgement (i.e., its validity as a +cognition), and although this universal assent should accidentally +happen, it could furnish no proof of agreement with the object; on the +contrary, it is the objective validity which alone constitutes the +basis of a necessary universal consent. + + {PREFACE ^paragraph 30} + +Hume would be quite satisfied with this system of universal +empiricism, for, as is well known, he desired nothing more than +that, instead of ascribing any objective meaning to the necessity in +the concept of cause, a merely subjective one should be assumed, viz., +custom, in order to deny that reason could judge about God, freedom, +and immortality; and if once his principles were granted, he was +certainly well able to deduce his conclusions therefrom, with all +logical coherence. But even Hume did not make his empiricism so +universal as to include mathematics. He holds the principles of +mathematics to be analytical; and if his were correct, they would +certainly be apodeictic also: but we could not infer from this that +reason has the faculty of forming apodeictic judgements in +philosophy also- that is to say, those which are synthetical +judgements, like the judgement of causality. But if we adopt a +universal empiricism, then mathematics will be included. + +Now if this science is in contradiction with a reason that admits +only empirical principles, as it inevitably is in the antinomy in +which mathematics prove the infinite divisibility of space, which +empiricism cannot admit; then the greatest possible evidence of +demonstration is in manifest contradiction with the alleged +conclusions from experience, and we are driven to ask, like +Cheselden's blind patient, "Which deceives me, sight or touch?" (for +empiricism is based on a necessity felt, rationalism on a necessity +seen). And thus universal empiricism reveals itself as absolute +scepticism. It is erroneous to attribute this in such an unqualified +sense to Hume, * since he left at least one certain touchstone (which +can only be found in a priori principles), although experience +consists not only of feelings, but also of judgements. + + + +* Names that designate the followers of a sect have always been +accompanied with much injustice; just as if one said, "N is an +Idealist." For although he not only admits, but even insists, that our +ideas of external things have actual objects of external things +corresponding to them, yet he holds that the form of the intuition +does not depend on them but on the human mind. + + + + {PREFACE ^paragraph 35} + +However, as in this philosophical and critical age such empiricism +can scarcely be serious, and it is probably put forward only as an +intellectual exercise and for the purpose of putting in a clearer +light, by contrast, the necessity of rational a priori principles, +we can only be grateful to those who employ themselves in this +otherwise uninstructive labour. + +INTRODUCTION + + INTRODUCTION. + + + + Of the Idea of a Critique of Practical Reason. + + + +The theoretical use of reason was concerned with objects of the +cognitive faculty only, and a critical examination of it with +reference to this use applied properly only to the pure faculty of +cognition; because this raised the suspicion, which was afterwards +confirmed, that it might easily pass beyond its limits, and be lost +among unattainable objects, or even contradictory notions. It is quite +different with the practical use of reason. In this, reason is +concerned with the grounds of determination of the will, which is a +faculty either to produce objects corresponding to ideas, or to +determine ourselves to the effecting of such objects (whether the +physical power is sufficient or not); that is, to determine our +causality. For here, reason can at least attain so far as to determine +the will, and has always objective reality in so far as it is the +volition only that is in question. The first question here then is +whether pure reason of itself alone suffices to determine the will, or +whether it can be a ground of determination only as dependent on +empirical conditions. Now, here there comes in a notion of causality +justified by the critique of the pure reason, although not capable +of being presented empirically, viz., that of freedom; and if we can +now discover means of proving that this property does in fact belong +to the human will (and so to the will of all rational beings), then it +will not only be shown that pure reason can be practical, but that +it alone, and not reason empirically limited, is indubitably +practical; consequently, we shall have to make a critical examination, +not of pure practical reason, but only of practical reason +generally. For when once pure reason is shown to exist, it needs no +critical examination. For reason itself contains the standard for +the critical examination of every use of it. The critique, then, of +practical reason generally is bound to prevent the empirically +conditioned reason from claiming exclusively to furnish the ground +of determination of the will. If it is proved that there is a +[practical] reason, its employment is alone immanent; the +empirically conditioned use, which claims supremacy, is on the +contrary transcendent and expresses itself in demands and precepts +which go quite beyond its sphere. This is just the opposite of what +might be said of pure reason in its speculative employment. + +However, as it is still pure reason, the knowledge of which is +here the foundation of its practical employment, the general outline +of the classification of a critique of practical reason must be +arranged in accordance with that of the speculative. We must, then, +have the Elements and the Methodology of it; and in the former an +Analytic as the rule of truth, and a Dialectic as the exposition and +dissolution of the illusion in the judgements of practical reason. But +the order in the subdivision of the Analytic will be the reverse of +that in the critique of the pure speculative reason. For, in the +present case, we shall commence with the principles and proceed to the +concepts, and only then, if possible, to the senses; whereas in the +case of the speculative reason we began with the senses and had to end +with the principles. The reason of this lies again in this: that now +we have to do with a will, and have to consider reason, not in its +relation to objects, but to this will and its causality. We must, +then, begin with the principles of a causality not empirically +conditioned, after which the attempt can be made to establish our +notions of the determining grounds of such a will, of their +application to objects, and finally to the subject and its sense +faculty. We necessarily begin with the law of causality from +freedom, that is, with a pure practical principle, and this determines +the objects to which alone it can be applied. + +BOOK_1|CHAPTER_1 + + FIRST PART. + + + + ELEMENTS OF PURE PRACTICAL REASON. + + + + BOOK I. The Analytic of Pure Practical Reason. + + + + CHAPTER I. Of the Principles of Pure Practical Reason. + + {BOOK_1|CHAPTER_1 ^paragraph 5} + + + + I. DEFINITION. + + + +Practical principles are propositions which contain a general +determination of the will, having under it several practical rules. +They are subjective, or maxims, when the condition is regarded by +the subject as valid only for his own will, but are objective, or +practical laws, when the condition is recognized as objective, that +is, valid for the will of every rational being. + + + + {BOOK_1|CHAPTER_1 ^paragraph 10} + + REMARK. + + + +Supposing that pure reason contains in itself a practical motive, +that is, one adequate to determine the will, then there are +practical laws; otherwise all practical principles will be mere +maxims. In case the will of a rational being is pathologically +affected, there may occur a conflict of the maxims with the +practical laws recognized by itself. For example, one may make it +his maxim to let no injury pass unrevenged, and yet he may see that +this is not a practical law, but only his own maxim; that, on the +contrary, regarded as being in one and the same maxim a rule for the +will of every rational being, it must contradict itself. In natural +philosophy the principles of what happens, (e.g., the principle of +equality of action and reaction in the communication of motion) are at +the same time laws of nature; for the use of reason there is +theoretical and determined by the nature of the object. In practical +philosophy, i.e., that which has to do only with the grounds of +determination of the will, the principles which a man makes for +himself are not laws by which one is inevitably bound; because +reason in practical matters has to do with the subject, namely, with +the faculty of desire, the special character of which may occasion +variety in the rule. The practical rule is always a product of reason, +because it prescribes action as a means to the effect. But in the case +of a being with whom reason does not of itself determine the will, +this rule is an imperative, i.e., a rule characterized by "shall," +which expresses the objective necessitation of the action and +signifies that, if reason completely determined the will, the action +would inevitably take place according to this rule. Imperatives, +therefore, are objectively valid, and are quite distinct from +maxims, which are subjective principles. The former either determine +the conditions of the causality of the rational being as an +efficient cause, i.e., merely in reference to the effect and the means +of attaining it; or they determine the will only, whether it is +adequate to the effect or not. The former would be hypothetical +imperatives, and contain mere precepts of skill; the latter, on the +contrary, would be categorical, and would alone be practical laws. +Thus maxims are principles, but not imperatives. Imperatives +themselves, however, when they are conditional (i.e., do not determine +the will simply as will, but only in respect to a desired effect, that +is, when they are hypothetical imperatives), are practical precepts +but not laws. Laws must be sufficient to determine the will as will, +even before I ask whether I have power sufficient for a desired +effect, or the means necessary to produce it; hence they are +categorical: otherwise they are not laws at all, because the necessity +is wanting, which, if it is to be practical, must be independent of +conditions which are pathological and are therefore only +contingently connected with the will. Tell a man, for example, that he +must be industrious and thrifty in youth, in order that he may not +want in old age; this is a correct and important practical precept +of the will. But it is easy to see that in this case the will is +directed to something else which it is presupposed that it desires; +and as to this desire, we must leave it to the actor himself whether +he looks forward to other resources than those of his own acquisition, +or does not expect to be old, or thinks that in case of future +necessity he will be able to make shift with little. Reason, from +which alone can spring a rule involving necessity, does, indeed, +give necessity to this precept (else it would not be an imperative), +but this is a necessity dependent on subjective conditions, and cannot +be supposed in the same degree in all subjects. But that reason may +give laws it is necessary that it should only need to presuppose +itself, because rules are objectively and universally valid only +when they hold without any contingent subjective conditions, which +distinguish one rational being from another. Now tell a man that he +should never make a deceitful promise, this is a rule which only +concerns his will, whether the purposes he may have can be attained +thereby or not; it is the volition only which is to be determined a +priori by that rule. If now it is found that this rule is +practically right, then it is a law, because it is a categorical +imperative. Thus, practical laws refer to the will only, without +considering what is attained by its causality, and we may disregard +this latter (as belonging to the world of sense) in order to have them +quite pure. + + + + II. THEOREM I. + + {BOOK_1|CHAPTER_1 ^paragraph 15} + + + +All practical principles which presuppose an object (matter) of +the faculty of desire as the ground of determination of the will are +empirical and can furnish no practical laws. + +By the matter of the faculty of desire I mean an object the +realization of which is desired. Now, if the desire for this object +precedes the practical rule and is the condition of our making it a +principle, then I say (in the first place) this principle is in that +case wholly empirical, for then what determines the choice is the idea +of an object and that relation of this idea to the subject by which +its faculty of desire is determined to its realization. Such a +relation to the subject is called the pleasure in the realization of +an object. This, then, must be presupposed as a condition of the +possibility of determination of the will. But it is impossible to know +a priori of any idea of an object whether it will be connected with +pleasure or pain, or be indifferent. In such cases, therefore, the +determining principle of the choice must be empirical and, +therefore, also the practical material principle which presupposes +it as a condition. + +In the second place, since susceptibility to a pleasure or pain +can be known only empirically and cannot hold in the same degree for +all rational beings, a principle which is based on this subjective +condition may serve indeed as a maxim for the subject which +possesses this susceptibility, but not as a law even to him (because +it is wanting in objective necessity, which must be recognized a +priori); it follows, therefore, that such a principle can never +furnish a practical law. + + + + {BOOK_1|CHAPTER_1 ^paragraph 20} + + III. THEOREM II. + + + +All material practical principles as such are of one and the same +kind and come under the general principle of self-love or private +happiness. + +Pleasure arising from the idea of the idea of the existence of a +thing, in so far as it is to determine the desire of this thing, is +founded on the susceptibility of the subject, since it depends on +the presence of an object; hence it belongs to sense (feeling), and +not to understanding, which expresses a relation of the idea to an +object according to concepts, not to the subject according to +feelings. It is, then, practical only in so far as the faculty of +desire is determined by the sensation of agreeableness which the +subject expects from the actual existence of the object. Now, a +rational being's consciousness of the pleasantness of life +uninterruptedly accompanying his whole existence is happiness; and the +principle which makes this the supreme ground of determination of +the will is the principle of self-love. All material principles, then, +which place the determining ground of the will in the pleasure or pain +to be received from the existence of any object are all of the same +kind, inasmuch as they all belong to the principle of self-love or +private happiness. + + + + {BOOK_1|CHAPTER_1 ^paragraph 25} + + COROLLARY. + + + +All material practical rules place the determining principle of +the will in the lower desires; and if there were no purely formal laws +of the will adequate to determine it, then we could not admit any +higher desire at all. + + + + REMARK I. + + {BOOK_1|CHAPTER_1 ^paragraph 30} + + + +It is surprising that men, otherwise acute, can think it possible to +distinguish between higher and lower desires, according as the ideas +which are connected with the feeling of pleasure have their origin +in the senses or in the understanding; for when we inquire what are +the determining grounds of desire, and place them in some expected +pleasantness, it is of no consequence whence the idea of this pleasing +object is derived, but only how much it pleases. Whether an idea has +its seat and source in the understanding or not, if it can only +determine the choice by presupposing a feeling of pleasure in the +subject, it follows that its capability of determining the choice +depends altogether on the nature of the inner sense, namely, that this +can be agreeably affected by it. However dissimilar ideas of objects +may be, though they be ideas of the understanding, or even of the +reason in contrast to ideas of sense, yet the feeling of pleasure, +by means of which they constitute the determining principle of the +will (the expected satisfaction which impels the activity to the +production of the object), is of one and the same kind, not only +inasmuch as it can only be known empirically, but also inasmuch as +it affects one and the same vital force which manifests itself in +the faculty of desire, and in this respect can only differ in degree +from every other ground of determination. Otherwise, how could we +compare in respect of magnitude two principles of determination, the +ideas of which depend upon different faculties, so as to prefer that +which affects the faculty of desire in the highest degree. The same +man may return unread an instructive book which he cannot again +obtain, in order not to miss a hunt; he may depart in the midst of a +fine speech, in order not to be late for dinner; he may leave a +rational conversation, such as he otherwise values highly, to take his +place at the gaming-table; he may even repulse a poor man whom he at +other times takes pleasure in benefiting, because he has only just +enough money in his pocket to pay for his admission to the theatre. If +the determination of his will rests on the feeling of the +agreeableness or disagreeableness that he expects from any cause, it +is all the same to him by what sort of ideas he will be affected. +The only thing that concerns him, in order to decide his choice, is, +how great, how long continued, how easily obtained, and how often +repeated, this agreeableness is. Just as to the man who wants money to +spend, it is all the same whether the gold was dug out of the mountain +or washed out of the sand, provided it is everywhere accepted at the +same value; so the man who cares only for the enjoyment of life does +not ask whether the ideas are of the understanding or the senses, +but only how much and how great pleasure they will give for the +longest time. It is only those that would gladly deny to pure reason +the power of determining the will, without the presupposition of any +feeling, who could deviate so far from their own exposition as to +describe as quite heterogeneous what they have themselves previously +brought under one and the same principle. Thus, for example, it is +observed that we can find pleasure in the mere exercise of power, in +the consciousness of our strength of mind in overcoming obstacles +which are opposed to our designs, in the culture of our mental +talents, etc.; and we justly call these more refined pleasures and +enjoyments, because they are more in our power than others; they do +not wear out, but rather increase the capacity for further enjoyment +of them, and while they delight they at the same time cultivate. But +to say on this account that they determine the will in a different way +and not through sense, whereas the possibility of the pleasure +presupposes a feeling for it implanted in us, which is the first +condition of this satisfaction; this is just as when ignorant +persons that like to dabble in metaphysics imagine matter so subtle, +so supersubtle that they almost make themselves giddy with it, and +then think that in this way they have conceived it as a spiritual +and yet extended being. If with Epicurus we make virtue determine +the will only by means of the pleasure it promises, we cannot +afterwards blame him for holding that this pleasure is of the same +kind as those of the coarsest senses. For we have no reason whatever +to charge him with holding that the ideas by which this feeling is +excited in us belong merely to the bodily senses. As far as can be +conjectured, he sought the source of many of them in the use of the +higher cognitive faculty, but this did not prevent him, and could +not prevent him, from holding on the principle above stated, that +the pleasure itself which those intellectual ideas give us, and by +which alone they can determine the will, is just of the same kind. +Consistency is the highest obligation of a philosopher, and yet the +most rarely found. The ancient Greek schools give us more examples +of it than we find in our syncretistic age, in which a certain shallow +and dishonest system of compromise of contradictory principles is +devised, because it commends itself better to a public which is +content to know something of everything and nothing thoroughly, so +as to please every party. + +The principle of private happiness, however much understanding and +reason may be used in it, cannot contain any other determining +principles for the will than those which belong to the lower +desires; and either there are no [higher] desires at all, or pure +reason must of itself alone be practical; that is, it must be able +to determine the will by the mere form of the practical rule without +supposing any feeling, and consequently without any idea of the +pleasant or unpleasant, which is the matter of the desire, and which +is always an empirical condition of the principles. Then only, when +reason of itself determines the will (not as the servant of the +inclination), it is really a higher desire to which that which is +pathologically determined is subordinate, and is really, and even +specifically, distinct from the latter, so that even the slightest +admixture of the motives of the latter impairs its strength and +superiority; just as in a mathematical demonstration the least +empirical condition would degrade and destroy its force and value. +Reason, with its practical law, determines the will immediately, not +by means of an intervening feeling of pleasure or pain, not even of +pleasure in the law itself, and it is only because it can, as pure +reason, be practical, that it is possible for it to be legislative. + + + + REMARK II. + + {BOOK_1|CHAPTER_1 ^paragraph 35} + + + +To be happy is necessarily the wish of every finite rational +being, and this, therefore, is inevitably a determining principle of +its faculty of desire. For we are not in possession originally of +satisfaction with our whole existence- a bliss which would imply a +consciousness of our own independent self-sufficiency this is a +problem imposed upon us by our own finite nature, because we have +wants and these wants regard the matter of our desires, that is, +something that is relative to a subjective feeling of pleasure or +pain, which determines what we need in order to be satisfied with +our condition. But just because this material principle of +determination can only be empirically known by the subject, it is +impossible to regard this problem as a law; for a law being +objective must contain the very same principle of determination of the +will in all cases and for all rational beings. For, although the +notion of happiness is in every case the foundation of practical +relation of the objects to the desires, yet it is only a general +name for the subjective determining principles, and determines nothing +specifically; whereas this is what alone we are concerned with in this +practical problem, which cannot be solved at all without such specific +determination. For it is every man's own special feeling of pleasure +and pain that decides in what he is to place his happiness, and even +in the same subject this will vary with the difference of his wants +according as this feeling changes, and thus a law which is +subjectively necessary (as a law of nature) is objectively a very +contingent practical principle, which can and must be very different +in different subjects and therefore can never furnish a law; since, in +the desire for happiness it is not the form (of conformity to law) +that is decisive, but simply the matter, namely, whether I am to +expect pleasure in following the law, and how much. Principles of +self-love may, indeed, contain universal precepts of skill (how to +find means to accomplish one's purpose), but in that case they are +merely theoretical principles; * as, for example, how he who would +like to eat bread should contrive a mill; but practical precepts +founded on them can never be universal, for the determining principle +of the desire is based on the feeling pleasure and pain, which can +never be supposed to be universally directed to the same objects. + + + +* Propositions which in mathematics or physics are called practical +ought properly to be called technical. For they have nothing to do +with the determination of the will; they only point out how a certain +effect is to be produced and are, therefore, just as theoretical as +any propositions which express the connection of a cause with an +effect. Now whoever chooses the effect must also choose the cause. + + + + {BOOK_1|CHAPTER_1 ^paragraph 40} + +Even supposing, however, that all finite rational beings were +thoroughly agreed as to what were the objects of their feelings of +pleasure and pain, and also as to the means which they must employ +to attain the one and avoid the other; still, they could by no means +set up the principle of self-love as a practical law, for this +unanimity itself would be only contingent. The principle of +determination would still be only subjectively valid and merely +empirical, and would not possess the necessity which is conceived in +every law, namely, an objective necessity arising from a priori +grounds; unless, indeed, we hold this necessity to be not at all +practical, but merely physical, viz., that our action is as inevitably +determined by our inclination, as yawning when we see others yawn. +It would be better to maintain that there are no practical laws at +all, but only counsels for the service of our desires, than to raise +merely subjective principles to the rank of practical laws, which have +objective necessity, and not merely subjective, and which must be +known by reason a priori, not by experience (however empirically +universal this may be). Even the rules of corresponding phenomena +are only called laws of nature (e.g., the mechanical laws), when we +either know them really a priori, or (as in the case of chemical laws) +suppose that they would be known a priori from objective grounds if +our insight reached further. But in the case of merely subjective +practical principles, it is expressly made a condition that they rest, +not on objective, but on subjective conditions of choice, and hence +that they must always be represented as mere maxims, never as +practical laws. This second remark seems at first sight to be mere +verbal refinement, but it defines the terms of the most important +distinction which can come into consideration in practical +investigations. + + + + IV. THEOREM II. + + + +A rational being cannot regard his maxims as practical universal +laws, unless he conceives them as principles which determine the will, +not by their matter, but by their form only. + + {BOOK_1|CHAPTER_1 ^paragraph 45} + +By the matter of a practical principle I mean the object of the +will. This object is either the determining ground of the will or it +is not. In the former case the rule of the will is subjected to an +empirical condition (viz., the relation of the determining idea to the +feeling of pleasure and pain), consequently it can not be a +practical law. Now, when we abstract from a law all matter, i.e., +every object of the will (as a determining principle), nothing is left +but the mere form of a universal legislation. Therefore, either a +rational being cannot conceive his subjective practical principles, +that is, his maxims, as being at the same time universal laws, or he +must suppose that their mere form, by which they are fitted for +universal legislation, is alone what makes them practical laws. + + + + REMARK. + + + +The commonest understanding can distinguish without instruction what +form of maxim is adapted for universal legislation, and what is not. +Suppose, for example, that I have made it my maxim to increase my +fortune by every safe means. Now, I have a deposit in my hands, the +owner of which is dead and has left no writing about it. This is +just the case for my maxim. I desire then to know whether that maxim +can also bold good as a universal practical law. I apply it, +therefore, to the present case, and ask whether it could take the form +of a law, and consequently whether I can by my maxim at the same +time give such a law as this, that everyone may deny a deposit of +which no one can produce a proof. I at once become aware that such a +principle, viewed as a law, would annihilate itself, because the +result would be that there would be no deposits. A practical law which +I recognise as such must be qualified for universal legislation; +this is an identical proposition and, therefore, self-evident. Now, if +I say that my will is subject to a practical law, I cannot adduce my +inclination (e.g., in the present case my avarice) as a principle of +determination fitted to be a universal practical law; for this is so +far from being fitted for a universal legislation that, if put in +the form of a universal law, it would destroy itself. + + {BOOK_1|CHAPTER_1 ^paragraph 50} + +It is, therefore, surprising that intelligent men could have thought +of calling the desire of happiness a universal practical law on the +ground that the desire is universal, and, therefore, also the maxim by +which everyone makes this desire determine his will. For whereas in +other cases a universal law of nature makes everything harmonious; +here, on the contrary, if we attribute to the maxim the universality +of a law, the extreme opposite of harmony will follow, the greatest +opposition and the complete destruction of the maxim itself and its +purpose. For, in that case, the will of all has not one and the same +object, but everyone has his own (his private welfare), which may +accidentally accord with the purposes of others which are equally +selfish, but it is far from sufficing for a law; because the +occasional exceptions which one is permitted to make are endless, +and cannot be definitely embraced in one universal rule. In this +manner, then, results a harmony like that which a certain satirical +poem depicts as existing between a married couple bent on going to +ruin, "O, marvellous harmony, what he wishes, she wishes also"; or +like what is said of the pledge of Francis I to the Emperor Charles V, +"What my brother Charles wishes that I wish also" (viz., Milan). +Empirical principles of determination are not fit for any universal +external legislation, but just as little for internal; for each man +makes his own subject the foundation of his inclination, and in the +same subject sometimes one inclination, sometimes another, has the +preponderance. To discover a law which would govern them all under +this condition, namely, bringing them all into harmony, is quite +impossible. + + + + V. PROBLEM I. + + + +Supposing that the mere legislative form of maxims is alone the +sufficient determining principle of a will, to find the nature of +the will which can be determined by it alone. + + {BOOK_1|CHAPTER_1 ^paragraph 55} + + Since the bare form of the law can only be conceived by reason, and +is, therefore, not an object of the senses, and consequently does +not belong to the class of phenomena, it follows that the idea of +it, which determines the will, is distinct from all the principles +that determine events in nature according to the law of causality, +because in their case the determining principles must themselves be +phenomena. Now, if no other determining principle can serve as a law +for the will except that universal legislative form, such a will +must be conceived as quite independent of the natural law of phenomena +in their mutual relation, namely, the law of causality; such +independence is called freedom in the strictest, that is, in the +transcendental, sense; consequently, a will which can have its law +in nothing but the mere legislative form of the maxim is a free will. + + + + VI. PROBLEM II. + + + +Supposing that a will is free, to find the law which alone is +competent to determine it necessarily. + + {BOOK_1|CHAPTER_1 ^paragraph 60} + +Since the matter of the practical law, i.e., an object of the maxim, +can never be given otherwise than empirically, and the free will is +independent on empirical conditions (that is, conditions belonging +to the world of sense) and yet is determinable, consequently a free +will must find its principle of determination in the law, and yet +independently of the matter of the law. But, besides the matter of the +law, nothing is contained in it except the legislative form. It is the +legislative form, then, contained in the maxim, which can alone +constitute a principle of determination of the [free] will. + + + + REMARK. + + + +Thus freedom and an unconditional practical law reciprocally imply +each other. Now I do not ask here whether they are in fact distinct, +or whether an unconditioned law is not rather merely the consciousness +of a pure practical reason and the latter identical with the +positive concept of freedom; I only ask, whence begins our knowledge +of the unconditionally practical, whether it is from freedom or from +the practical law? Now it cannot begin from freedom, for of this we +cannot be immediately conscious, since the first concept of it is +negative; nor can we infer it from experience, for experience gives us +the knowledge only of the law of phenomena, and hence of the mechanism +of nature, the direct opposite of freedom. It is therefore the moral +law, of which we become directly conscious (as soon as we trace for +ourselves maxims of the will), that first presents itself to us, and +leads directly to the concept of freedom, inasmuch as reason +presents it as a principle of determination not to be outweighed by +any sensible conditions, nay, wholly independent of them. But how is +the consciousness, of that moral law possible? We can become conscious +of pure practical laws just as we are conscious of pure theoretical +principles, by attending to the necessity with which reason prescribes +them and to the elimination of all empirical conditions, which it +directs. The concept of a pure will arises out of the former, as +that of a pure understanding arises out of the latter. That this is +the true subordination of our concepts, and that it is morality that +first discovers to us the notion of freedom, hence that it is +practical reason which, with this concept, first proposes to +speculative reason the most insoluble problem, thereby placing it in +the greatest perplexity, is evident from the following +consideration: Since nothing in phenomena can be explained by the +concept of freedom, but the mechanism of nature must constitute the +only clue; moreover, when pure reason tries to ascend in the series of +causes to the unconditioned, it falls into an antinomy which is +entangled in incomprehensibilities on the one side as much as the +other; whilst the latter (namely, mechanism) is at least useful in the +explanation of phenomena, therefore no one would ever have been so +rash as to introduce freedom into science, had not the moral law, +and with it practical reason, come in and forced this notion upon +us. Experience, however, confirms this order of notions. Suppose +some one asserts of his lustful appetite that, when the desired object +and the opportunity are present, it is quite irresistible. [Ask +him]- if a gallows were erected before the house where he finds this +opportunity, in order that he should be hanged thereon immediately +after the gratification of his lust, whether he could not then control +his passion; we need not be long in doubt what he would reply. Ask +him, however- if his sovereign ordered him, on pain of the same +immediate execution, to bear false witness against an honourable +man, whom the prince might wish to destroy under a plausible +pretext, would he consider it possible in that case to overcome his +love of life, however great it may be. He would perhaps not venture to +affirm whether he would do so or not, but he must unhesitatingly admit +that it is possible to do so. He judges, therefore, that he can do a +certain thing because he is conscious that he ought, and he recognizes +that he is free- a fact which but for the moral law he would never +have known. + + {BOOK_1|CHAPTER_1 ^paragraph 65} + + + + VII. FUNDAMENTAL LAW OF THE PURE PRACTICAL REASON. + + + +Act so that the maxim of thy will can always at the same time hold +good as a principle of universal legislation. + + + + {BOOK_1|CHAPTER_1 ^paragraph 70} + + REMARK. + + + +Pure geometry has postulates which are practical propositions, but +contain nothing further than the assumption that we can do something +if it is required that we should do it, and these are the only +geometrical propositions that concern actual existence. They are, +then, practical rules under a problematical condition of the will; but +here the rule says: We absolutely must proceed in a certain manner. +The practical rule is, therefore, unconditional, and hence it is +conceived a priori as a categorically practical proposition by which +the will is objectively determined absolutely and immediately (by +the practical rule itself, which thus is in this case a law); for pure +reason practical of itself is here directly legislative. The will is +thought as independent on empirical conditions, and, therefore, as +pure will determined by the mere form of the law, and this principle +of determination is regarded as the supreme condition of all maxims. +The thing is strange enough, and has no parallel in all the rest of +our practical knowledge. For the a priori thought of a possible +universal legislation which is therefore merely problematical, is +unconditionally commanded as a law without borrowing anything from +experience or from any external will. This, however, is not a +precept to do something by which some desired effect can be attained +(for then the will would depend on physical conditions), but a rule +that determines the will a priori only so far as regards the forms +of its maxims; and thus it is at least not impossible to conceive that +a law, which only applies to the subjective form of principles, yet +serves as a principle of determination by means of the objective +form of law in general. We may call the consciousness of this +fundamental law a fact of reason, because we cannot reason it out from +antecedent data of reason, e.g., the consciousness of freedom (for +this is not antecedently given), but it forces itself on us as a +synthetic a priori proposition, which is not based on any intuition, +either pure or empirical. It would, indeed, be analytical if the +freedom of the will were presupposed, but to presuppose freedom as a +positive concept would require an intellectual intuition, which cannot +here be assumed; however, when we regard this law as given, it must be +observed, in order not to fall into any misconception, that it is +not an empirical fact, but the sole fact of the pure reason, which +thereby announces itself as originally legislative (sic volo, sic +jubeo). + + + + COROLLARY. + + {BOOK_1|CHAPTER_1 ^paragraph 75} + + + +Pure reason is practical of itself alone and gives (to man) a +universal law which we call the moral law. + + + + REMARK. + + + + {BOOK_1|CHAPTER_1 ^paragraph 80} + +The fact just mentioned is undeniable. It is only necessary to +analyse the judgement that men pass on the lawfulness of their +actions, in order to find that, whatever inclination may say to the +contrary, reason, incorruptible and self-constrained, always +confronts the maxim of the will in any action with the pure will, that +is, with itself, considering itself as a priori practical. Now this +principle of morality, just on account of the universality of the +legislation which makes it the formal supreme determining principle of +the will, without regard to any subjective differences, is declared by +the reason to be a law for all rational beings, in so far as they have +a will, that is, a power to determine their causality by the +conception of rules; and, therefore, so far as they are capable of +acting according to principles, and consequently also according to +practical a priori principles (for these alone have the necessity that +reason requires in a principle). It is, therefore, not limited to +men only, but applies to all finite beings that possess reason and +will; nay, it even includes the Infinite Being as the supreme +intelligence. In the former case, however, the law has the form of +an imperative, because in them, as rational beings, we can suppose a +pure will, but being creatures affected with wants and physical +motives, not a holy will, that is, one which would be incapable of any +maxim conflicting with the moral law. In their case, therefore, the +moral law is an imperative, which commands categorically, because +the law is unconditioned; the relation of such a will to this law is +dependence under the name of obligation, which implies a constraint to +an action, though only by reason and its objective law; and this +action is called duty, because an elective will, subject to +pathological affections (though not determined by them, and, +therefore, still free), implies a wish that arises from subjective +causes and, therefore, may often be opposed to the pure objective +determining principle; whence it requires the moral constraint of a +resistance of the practical reason, which may be called an internal, +but intellectual, compulsion. In the supreme intelligence the elective +will is rightly conceived as incapable of any maxim which could not at +the same time be objectively a law; and the notion of holiness, +which on that account belongs to it, places it, not indeed above all +practical laws, but above all practically restrictive laws, and +consequently above obligation and duty. This holiness of will is, +however, a practical idea, which must necessarily serve as a type to +which finite rational beings can only approximate indefinitely, and +which the pure moral law, which is itself on this account called holy, +constantly and rightly holds before their eyes. The utmost that finite +practical reason can effect is to be certain of this indefinite +progress of one's maxims and of their steady disposition to advance. +This is virtue, and virtue, at least as a naturally acquired +faculty, can never be perfect, because assurance in such a case +never becomes apodeictic certainty and, when it only amounts to +persuasion, is very dangerous. + + + + VIII. THEOREM IV. + + + +The autonomy of the will is the sole principle of all moral laws and +of all duties which conform to them; on the other hand, heteronomy +of the elective will not only cannot be the basis of any obligation, +but is, on the contrary, opposed to the principle thereof and to the +morality of the will. + + {BOOK_1|CHAPTER_1 ^paragraph 85} + +In fact the sole principle of morality consists in the +independence on all matter of the law (namely, a desired object), +and in the determination of the elective will by the mere universal +legislative form of which its maxim must be capable. Now this +independence is freedom in the negative sense, and this +self-legislation of the pure, and therefore practical, reason is +freedom in the positive sense. Thus the moral law expresses nothing +else than the autonomy of the pure practical reason; that is, freedom; +and this is itself the formal condition of all maxims, and on this +condition only can they agree with the supreme practical law. If +therefore the matter of the volition, which can be nothing else than +the object of a desire that is connected with the law, enters into the +practical law, as the condition of its possibility, there results +heteronomy of the elective will, namely, dependence on the physical +law that we should follow some impulse or inclination. In that case +the will does not give itself the law, but only the precept how +rationally to follow pathological law; and the maxim which, in such +a case, never contains the universally legislative form, not only +produces no obligation, but is itself opposed to the principle of a +pure practical reason and, therefore, also to the moral disposition, +even though the resulting action may be conformable to the law. + + + + REMARK. + + + +Hence a practical precept, which contains a material (and +therefore empirical) condition, must never be reckoned a practical +law. For the law of the pure will, which is free, brings the will into +a sphere quite different from the empirical; and as the necessity +involved in the law is not a physical necessity, it can only consist +in the formal conditions of the possibility of a law in general. All +the matter of practical rules rests on subjective conditions, which +give them only a conditional universality (in case I desire this or +that, what I must do in order to obtain it), and they all turn on +the principle of private happiness. Now, it is indeed undeniable +that every volition must have an object, and therefore a matter; but +it does not follow that this is the determining principle and the +condition of the maxim; for, if it is so, then this cannot be +exhibited in a universally legislative form, since in that case the +expectation of the existence of the object would be the determining +cause of the choice, and the volition must presuppose the dependence +of the faculty of desire on the existence of something; but this +dependence can only be sought in empirical conditions and, +therefore, can never furnish a foundation for a necessary and +universal rule. Thus, the happiness of others may be the object of the +will of a rational being. But if it were the determining principle +of the maxim, we must assume that we find not only a rational +satisfaction in the welfare of others, but also a want such as the +sympathetic disposition in some men occasions. But I cannot assume the +existence of this want in every rational being (not at all in God). +The matter, then, of the maxim may remain, but it must not be the +condition of it, else the maxim could not be fit for a law. Hence, the +mere form of law, which limits the matter, must also be a reason for +adding this matter to the will, not for presupposing it. For +example, let the matter be my own happiness. This (rule), if I +attribute it to everyone (as, in fact, I may, in the case of every +finite being), can become an objective practical law only if I include +the happiness of others. Therefore, the law that we should promote the +happiness of others does not arise from the assumption that this is an +object of everyone's choice, but merely from this, that the form of +universality which reason requires as the condition of giving to a +maxim of self-love the objective validity of a law is the principle +that determines the will. Therefore it was not the object (the +happiness of others) that determined the pure will, but it was the +form of law only, by which I restricted my maxim, founded on +inclination, so as to give it the universality of a law, and thus to +adapt it to the practical reason; and it is this restriction alone, +and not the addition of an external spring, that can give rise to +the notion of the obligation to extend the maxim of my self-love to +the happiness of others. + + {BOOK_1|CHAPTER_1 ^paragraph 90} + + + + REMARK II. + + + +The direct opposite of the principle of morality is, when the +principle of private happiness is made the determining principle of +the will, and with this is to be reckoned, as I have shown above, +everything that places the determining principle which is to serve +as a law, anywhere but in the legislative form of the maxim. This +contradiction, however, is not merely logical, like that which would +arise between rules empirically conditioned, if they were raised to +the rank of necessary principles of cognition, but is practical, and +would ruin morality altogether were not the voice of reason in +reference to the will so clear, so irrepressible, so distinctly +audible, even to the commonest men. It can only, indeed, be maintained +in the perplexing speculations of the schools, which are bold enough +to shut their ears against that heavenly voice, in order to support +a theory that costs no trouble. + +Suppose that an acquaintance whom you otherwise liked were to +attempt to justify himself to you for having borne false witness, +first by alleging the, in his view, sacred duty of consulting his +own happiness; then by enumerating the advantages which he had +gained thereby, pointing out the prudence he had shown in securing +himself against detection, even by yourself, to whom he now reveals +the secret, only in order that he may be able to deny it at any +time; and suppose he were then to affirm, in all seriousness, that +he has fulfilled a true human duty; you would either laugh in his +face, or shrink back from him with disgust; and yet, if a man has +regulated his principles of action solely with a view to his own +advantage, you would have nothing whatever to object against this mode +of proceeding. Or suppose some one recommends you a man as steward, as +a man to whom you can blindly trust all your affairs; and, in order to +inspire you with confidence, extols him as a prudent man who +thoroughly understands his own interest, and is so indefatigably +active that he lets slip no opportunity of advancing it; lastly, +lest you should be afraid of finding a vulgar selfishness in him, +praises the good taste with which he lives; not seeking his pleasure +in money-making, or in coarse wantonness, but in the enlargement of +his knowledge, in instructive intercourse with a select circle, and +even in relieving the needy; while as to the means (which, of +course, derive all their value from the end), he is not particular, +and is ready to use other people's money for the purpose as if it were +his own, provided only he knows that he can do so safely, and +without discovery; you would either believe that the recommender was +mocking you, or that he had lost his senses. So sharply and clearly +marked are the boundaries of morality and self-love that even the +commonest eye cannot fail to distinguish whether a thing belongs to +the one or the other. The few remarks that follow may appear +superfluous where the truth is so plain, but at least they may serve +to give a little more distinctness to the judgement of common sense. + + {BOOK_1|CHAPTER_1 ^paragraph 95} + +The principle of happiness may, indeed, furnish maxims, but never +such as would be competent to be laws of the will, even if universal +happiness were made the object. For since the knowledge of this +rests on mere empirical data, since every man's judgement on it +depends very much on his particular point of view, which is itself +moreover very variable, it can supply only general rules, not +universal; that is, it can give rules which on the average will most +frequently fit, but not rules which must hold good always and +necessarily; hence, no practical laws can be founded on it. Just +because in this case an object of choice is the foundation of the rule +and must therefore precede it, the rule can refer to nothing but +what is [felt], and therefore it refers to experience and is founded +on it, and then the variety of judgement must be endless. This +principle, therefore, does not prescribe the same practical rules to +all rational beings, although the rules are all included under a +common title, namely, that of happiness. The moral law, however, is +conceived as objectively necessary, only because it holds for everyone +that has reason and will. + +The maxim of self-love (prudence) only advises; the law of +morality commands. Now there is a great difference between that +which we are advised to do and that to which we are obliged. + +The commonest intelligence can easily and without hesitation see +what, on the principle of autonomy of the will, requires to be done; +but on supposition of heteronomy of the will, it is hard and +requires knowledge of the world to see what is to be done. That is +to say, what duty is, is plain of itself to everyone; but what is to +bring true durable advantage, such as will extend to the whole of +one's existence, is always veiled in impenetrable obscurity; and +much prudence is required to adapt the practical rule founded on it to +the ends of life, even tolerably, by making proper exceptions. But the +moral law commands the most punctual obedience from everyone; it must, +therefore, not be so difficult to judge what it requires to be done, +that the commonest unpractised understanding, even without worldly +prudence, should fail to apply it rightly. + +It is always in everyone's power to satisfy the categorical +command of morality; whereas it is seldom possible, and by no means so +to everyone, to satisfy the empirically conditioned precept of +happiness, even with regard to a single purpose. The reason is that in +the former case there is question only of the maxim, which must be +genuine and pure; but in the latter case there is question also of +one's capacity and physical power to realize a desired object. A +command that everyone should try to make himself happy would be +foolish, for one never commands anyone to do what he of himself +infallibly wishes to do. We must only command the means, or rather +supply them, since he cannot do everything that he wishes. But to +command morality under the name of duty is quite rational; for, in the +first place, not everyone is willing to obey its precepts if they +oppose his inclinations; and as to the means of obeying this law, +these need not in this case be taught, for in this respect whatever he +wishes to do he can do. + +He who has lost at play may be vexed at himself and his folly, but +if he is conscious of having cheated at play (although he has gained +thereby), he must despise himself as soon as he compares himself +with the moral law. This must, therefore, be something different +from the principle of private happiness. For a man must have a +different criterion when he is compelled to say to himself: "I am a +worthless fellow, though I have filled my purse"; and when he approves +himself, and says: "I am a prudent man, for I have enriched my +treasure." + + {BOOK_1|CHAPTER_1 ^paragraph 100} + +Finally, there is something further in the idea of our practical +reason, which accompanies the transgression of a moral law- namely, +its ill desert. Now the notion of punishment, as such, cannot be +united with that of becoming a partaker of happiness; for although +he who inflicts the punishment may at the same time have the +benevolent purpose of directing this punishment to this end, yet it +must first be justified in itself as punishment, i.e., as mere harm, +so that if it stopped there, and the person punished could get no +glimpse of kindness hidden behind this harshness, he must yet admit +that justice was done him, and that his reward was perfectly +suitable to his conduct. In every punishment, as such, there must +first be justice, and this constitutes the essence of the notion. +Benevolence may, indeed, be united with it, but the man who has +deserved punishment has not the least reason to reckon upon this. +Punishment, then, is a physical evil, which, though it be not +connected with moral evil as a natural consequence, ought to be +connected with it as a consequence by the principles of a moral +legislation. Now, if every crime, even without regarding the +physical consequence with respect to the actor, is in itself +punishable, that is, forfeits happiness (at least partially), it is +obviously absurd to say that the crime consisted just in this, that he +has drawn punishment on himself, thereby injuring his private +happiness (which, on the principle of self-love, must be the proper +notion of all crime). According to this view, the punishment would +be the reason for calling anything a crime, and justice would, on +the contrary, consist in omitting all punishment, and even +preventing that which naturally follows; for, if this were done, there +would no longer be any evil in the action, since the harm which +otherwise followed it, and on account of which alone the action was +called evil, would now be prevented. To look, however, on all +rewards and punishments as merely the machinery in the hand of a +higher power, which is to serve only to set rational creatures +striving after their final end (happiness), this is to reduce the will +to a mechanism destructive of freedom; this is so evident that it need +not detain us. + +More refined, though equally false, is the theory of those who +suppose a certain special moral sense, which sense and not reason +determines the moral law, and in consequence of which the +consciousness of virtue is supposed to be directly connected with +contentment and pleasure; that of vice, with mental dissatisfaction +and pain; thus reducing the whole to the desire of private +happiness. Without repeating what has been said above, I will here +only remark the fallacy they fall into. In order to imagine the +vicious man as tormented with mental dissatisfaction by the +consciousness of his transgressions, they must first represent him +as in the main basis of his character, at least in some degree, +morally good; just as he who is pleased with the consciousness of +right conduct must be conceived as already virtuous. The notion of +morality and duty must, therefore, have preceded any regard to this +satisfaction, and cannot be derived from it. A man must first +appreciate the importance of what we call duty, the authority of the +moral law, and the immediate dignity which the following of it gives +to the person in his own eyes, in order to feel that satisfaction in +the consciousness of his conformity to it and the bitter remorse +that accompanies the consciousness of its transgression. It is, +therefore, impossible to feel this satisfaction or dissatisfaction +prior to the knowledge of obligation, or to make it the basis of the +latter. A man must be at least half honest in order even to be able to +form a conception of these feelings. I do not deny that as the human +will is, by virtue of liberty, capable of being immediately determined +by the moral law, so frequent practice in accordance with this +principle of determination can, at least, produce subjectively a +feeling of satisfaction; on the contrary, it is a duty to establish +and to cultivate this, which alone deserves to be called properly +the moral feeling; but the notion of duty cannot be derived from it, +else we should have to suppose a feeling for the law as such, and thus +make that an object of sensation which can only be thought by the +reason; and this, if it is not to be a flat contradiction, would +destroy all notion of duty and put in its place a mere mechanical play +of refined inclinations sometimes contending with the coarser. + +If now we compare our formal supreme principle of pure practical +reason (that of autonomy of the will) with all previous material +principles of morality, we can exhibit them all in a table in which +all possible cases are exhausted, except the one formal principle; and +thus we can show visibly that it is vain to look for any other +principle than that now proposed. In fact all possible principles of +determination of the will are either merely subjective, and +therefore empirical, or are also objective and rational; and both +are either external or internal. + + + +Practical Material Principles of Determination taken as the +Foundation of Morality, are: + + {BOOK_1|CHAPTER_1 ^paragraph 105} + + + + SUBJECTIVE. + + + + EXTERNAL INTERNAL + + Education Physical feeling + + {BOOK_1|CHAPTER_1 ^paragraph 110} + + (Montaigne) (Epicurus) + + The civil Moral feeling + + Constitution (Hutcheson) + + (Mandeville) + + + + {BOOK_1|CHAPTER_1 ^paragraph 115} + + OBJECTIVE. + + + + INTERNAL EXTERNAL + + Perfection Will of God + + (Wolf and the (Crusius and other + + {BOOK_1|CHAPTER_1 ^paragraph 120} + + Stoics) theological Moralists) + + + +Those of the upper table are all empirical and evidently incapable +of furnishing the universal principle of morality; but those in the +lower table are based on reason (for perfection as a quality of +things, and the highest perfection conceived as substance, that is, +God, can only be thought by means of rational concepts). But the +former notion, namely, that of perfection, may either be taken in a +theoretic signification, and then it means nothing but the +completeness of each thing in its own kind (transcendental), or that +of a thing merely as a thing (metaphysical); and with that we are +not concerned here. But the notion of perfection in a practical +sense is the fitness or sufficiency of a thing for all sorts of +purposes. This perfection, as a quality of man and consequently +internal, is nothing but talent and, what strengthens or completes +this, skill. Supreme perfection conceived as substance, that is God, +and consequently external (considered practically), is the sufficiency +of this being for all ends. Ends then must first be given, +relatively to which only can the notion of perfection (whether +internal in ourselves or external in God) be the determining principle +of the will. But an end- being an object which must precede the +determination of the will by a practical rule and contain the ground +of the possibility of this determination, and therefore contain also +the matter of the will, taken as its determining principle- such an +end is always empirical and, therefore, may serve for the Epicurean +principle of the happiness theory, but not for the pure rational +principle of morality and duty. Thus, talents and the improvement of +them, because they contribute to the advantages of life; or the will +of God, if agreement with it be taken as the object of the will, +without any antecedent independent practical principle, can be motives +only by reason of the happiness expected therefrom. Hence it +follows, first, that all the principles here stated are material; +secondly, that they include all possible material principles; and, +finally, the conclusion, that since material principles are quite +incapable of furnishing the supreme moral law (as has been shown), the +formal practical principle of the pure reason (according to which the +mere form of a universal legislation must constitute the supreme and +immediate determining principle of the will) is the only one +possible which is adequate to furnish categorical imperatives, that +is, practical laws (which make actions a duty), and in general to +serve as the principle of morality, both in criticizing conduct and +also in its application to the human will to determine it. + + + +I. Of the Deduction of the Fundamental Principles of Pure +Practical Reason. + + {BOOK_1|CHAPTER_1 ^paragraph 125} + + + +This Analytic shows that pure reason can be practical, that is, +can of itself determine the will independently of anything +empirical; and this it proves by a fact in which pure reason in us +proves itself actually practical, namely, the autonomy shown in the +fundamental principle of morality, by which reason determines the will +to action. + +It shows at the same time that this fact is inseparably connected +with the consciousness of freedom of the will, nay, is identical +with it; and by this the will of a rational being, although as +belonging to the world of sense it recognizes itself as necessarily +subject to the laws of causality like other efficient causes; yet, +at the same time, on another side, namely, as a being in itself, is +conscious of existing in and being determined by an intelligible order +of things; conscious not by virtue of a special intuition of itself, +but by virtue of certain dynamical laws which determine its +causality in the sensible world; for it has been elsewhere proved that +if freedom is predicated of us, it transports us into an +intelligible order of things. + +Now, if we compare with this the analytical part of the critique +of pure speculative reason, we shall see a remarkable contrast. +There it was not fundamental principles, but pure, sensible +intuition (space and time), that was the first datum that made a +priori knowledge possible, though only of objects of the senses. +Synthetical principles could not be derived from mere concepts without +intuition; on the contrary, they could only exist with reference to +this intuition, and therefore to objects of possible experience, since +it is the concepts of the understanding, united with this intuition, +which alone make that knowledge possible which we call experience. +Beyond objects of experience, and therefore with regard to things as +noumena, all positive knowledge was rightly disclaimed for speculative +reason. This reason, however, went so far as to establish with +certainty the concept of noumena; that is, the possibility, nay, the +necessity, of thinking them; for example, it showed against all +objections that the supposition of freedom, negatively considered, was +quite consistent with those principles and limitations of pure +theoretic reason. But it could not give us any definite enlargement of +our knowledge with respect to such objects, but, on the contrary, +cut off all view of them altogether. + +On the other hand, the moral law, although it gives no view, yet +gives us a fact absolutely inexplicable from any data of the +sensible world, and the whole compass of our theoretical use of +reason, a fact which points to a pure world of the understanding, nay, +even defines it positively and enables us to know something of it, +namely, a law. + + {BOOK_1|CHAPTER_1 ^paragraph 130} + +This law (as far as rational beings are concerned) gives to the +world of sense, which is a sensible system of nature, the form of a +world of the understanding, that is, of a supersensible system of +nature, without interfering with its mechanism. Now, a system of +nature, in the most general sense, is the existence of things under +laws. The sensible nature of rational beings in general is their +existence under laws empirically conditioned, which, from the point of +view of reason, is heteronomy. The supersensible nature of the same +beings, on the other hand, is their existence according to laws +which are independent of every empirical condition and, therefore, +belong to the autonomy of pure reason. And, since the laws by which +the existence of things depends on cognition are practical, +supersensible nature, so far as we can form any notion of it, is +nothing else than a system of nature under the autonomy of pure +practical reason. Now, the law of this autonomy is the moral law, +which, therefore, is the fundamental law of a supersensible nature, +and of a pure world of understanding, whose counterpart must exist +in the world of sense, but without interfering with its laws. We might +call the former the archetypal world (natura archetypa), which we only +know in the reason; and the latter the ectypal world (natura +ectypa), because it contains the possible effect of the idea of the +former which is the determining principle of the will. For the moral +law, in fact, transfers us ideally into a system in which pure reason, +if it were accompanied with adequate physical power, would produce the +summum bonum, and it determines our will to give the sensible world +the form of a system of rational beings. + +The least attention to oneself proves that this idea really serves +as the model for the determinations of our will. + +When the maxim which I am disposed to follow in giving testimony +is tested by the practical reason, I always consider what it would +be if it were to hold as a universal law of nature. It is manifest +that in this view it would oblige everyone to speak the truth. For +it cannot hold as a universal law of nature that statements should +be allowed to have the force of proof and yet to be purposely +untrue. Similarly, the maxim which I adopt with respect to disposing +freely of my life is at once determined, when I ask myself what it +should be, in order that a system, of which it is the law, should +maintain itself. It is obvious that in such a system no one could +arbitrarily put an end to his own life, for such an arrangement +would not be a permanent order of things. And so in all similar cases. +Now, in nature, as it actually is an object of experience, the free +will is not of itself determined to maxims which could of themselves +be the foundation of a natural system of universal laws, or which +could even be adapted to a system so constituted; on the contrary, its +maxims are private inclinations which constitute, indeed, a natural +whole in conformity with pathological (physical) laws, but could not +form part of a system of nature, which would only be possible +through our will acting in accordance with pure practical laws. Yet we +are, through reason, conscious of a law to which all our maxims are +subject, as though a natural order must be originated from our will. +This law, therefore, must be the idea of a natural system not given in +experience, and yet possible through freedom; a system, therefore, +which is supersensible, and to which we give objective reality, at +least in a practical point of view, since we look on it as an object +of our will as pure rational beings. + +Hence the distinction between the laws of a natural system to +which the will is subject, and of a natural system which is subject to +a will (as far as its relation to its free actions is concerned), +rests on this, that in the former the objects must be causes of the +ideas which determine the will; whereas in the latter the will is +the cause of the objects; so that its causality has its determining +principle solely in the pure faculty of reason, which may therefore be +called a pure practical reason. + +There are therefore two very distinct problems: how, on the one +side, pure reason can cognise objects a priori, and how on the other +side it can be an immediate determining principle of the will, that +is, of the causality of the rational being with respect to the reality +of objects (through the mere thought of the universal validity of +its own maxims as laws). + + {BOOK_1|CHAPTER_1 ^paragraph 135} + +The former, which belongs to the critique of the pure speculative +reason, requires a previous explanation, how intuitions without +which no object can be given, and, therefore, none known +synthetically, are possible a priori; and its solution turns out to be +that these are all only sensible and, therefore, do not render +possible any speculative knowledge which goes further than possible +experience reaches; and that therefore all the principles of that pure +speculative reason avail only to make experience possible; either +experience of given objects or of those that may be given ad +infinitum, but never are completely given. + +The latter, which belongs to the critique of practical reason, +requires no explanation how the objects of the faculty of desire are +possible, for that being a problem of the theoretical knowledge of +nature is left to the critique of the speculative reason, but only how +reason can determine the maxims of the will; whether this takes +place only by means of empirical ideas as principles of determination, +or whether pure reason can be practical and be the law of a possible +order of nature, which is not empirically knowable. The possibility of +such a supersensible system of nature, the conception of which can +also be the ground of its reality through our own free will, does +not require any a priori intuition (of an intelligible world) which, +being in this case supersensible, would be impossible for us. For +the question is only as to the determining principle of volition in +its maxims, namely, whether it is empirical, or is a conception of the +pure reason (having the legal character belonging to it in general), +and how it can be the latter. It is left to the theoretic principles +of reason to decide whether the causality of the will suffices for the +realization of the objects or not, this being an inquiry into the +possibility of the objects of the volition. Intuition of these objects +is therefore of no importance to the practical problem. We are here +concerned only with the determination of the will and the +determining principles of its maxims as a free will, not at all with +the result. For, provided only that the will conforms to the law of +pure reason, then let its power in execution be what it may, whether +according to these maxims of legislation of a possible system of +nature any such system really results or not, this is no concern of +the critique, which only inquires whether, and in what way, pure +reason can be practical, that is directly determine the will. + +In this inquiry criticism may and must begin with pure practical +laws and their reality. But instead of intuition it takes as their +foundation the conception of their existence in the intelligible +world, namely, the concept of freedom. For this concept has no other +meaning, and these laws are only possible in relation to freedom of +the will; but freedom being supposed, they are necessary; or +conversely freedom is necessary because those laws are necessary, +being practical postulates. It cannot be further explained how this +consciousness of the moral law, or, what is the same thing, of +freedom, is possible; but that it is admissible is well established in +the theoretical critique. + +The exposition of the supreme principle of practical reason is now +finished; that is to say, it has been shown first, what it +contains, that it subsists for itself quite a priori and independent +of empirical principles; and next in what it is distinguished from all +other practical principles. With the deduction, that is, the +justification of its objective and universal validity, and the +discernment of the possibility of such a synthetical proposition a +priori, we cannot expect to succeed so well as in the case of the +principles of pure theoretical reason. For these referred to objects +of possible experience, namely, to phenomena, and we could prove +that these phenomena could be known as objects of experience only by +being brought under the categories in accordance with these laws; +and consequently that all possible experience must conform to these +laws. But I could not proceed in this way with the deduction of the +moral law. For this does not concern the knowledge of the properties +of objects, which may be given to the reason from some other source; +but a knowledge which can itself be the ground of the existence of the +objects, and by which reason in a rational being has causality, +i.e., pure reason, which can be regarded as a faculty immediately +determining the will. + +Now all our human insight is at an end as soon as we have arrived at +fundamental powers or faculties, for the possibility of these cannot +be understood by any means, and just as little should it be +arbitrarily invented and assumed. Therefore, in the theoretic use of +reason, it is experience alone that can justify us in assuming them. +But this expedient of adducing empirical proofs, instead of a +deduction from a priori sources of knowledge, is denied us here in +respect to the pure practical faculty of reason. For whatever requires +to draw the proof of its reality from experience must depend for the +grounds of its possibility on principles of experience; and pure, +yet practical, reason by its very notion cannot be regarded as such. +Further, the moral law is given as a fact of pure reason of which we +are a priori conscious, and which is apodeictically certain, though it +be granted that in experience no example of its exact fulfilment can +be found. Hence, the objective reality of the moral law cannot be +proved by any deduction by any efforts of theoretical reason, +whether speculative or empirically supported, and therefore, even if +we renounced its apodeictic certainty, it could not be proved a +posteriori by experience, and yet it is firmly established of itself. + + {BOOK_1|CHAPTER_1 ^paragraph 140} + +But instead of this vainly sought deduction of the moral +principle, something else is found which was quite unexpected, namely, +that this moral principle serves conversely as the principle of the +deduction of an inscrutable faculty which no experience could prove, +but of which speculative reason was compelled at least to assume the +possibility (in order to find amongst its cosmological ideas the +unconditioned in the chain of causality, so as not to contradict +itself)- I mean the faculty of freedom. The moral law, which itself +does not require a justification, proves not merely the possibility of +freedom, but that it really belongs to beings who recognize this law +as binding on themselves. The moral law is in fact a law of the +causality of free agents and, therefore, of the possibility of a +supersensible system of nature, just as the metaphysical law of events +in the world of sense was a law of causality of the sensible system of +nature; and it therefore determines what speculative philosophy was +compelled to leave undetermined, namely, the law for a causality, +the concept of which in the latter was only negative; and therefore +for the first time gives this concept objective reality. + +This sort of credential of the moral law, viz., that it is set forth +as a principle of the deduction of freedom, which is a causality of +pure reason, is a sufficient substitute for all a priori +justification, since theoretic reason was compelled to assume at least +the possibility of freedom, in order to satisfy a want of its own. For +the moral law proves its reality, so as even to satisfy the critique +of the speculative reason, by the fact that it adds a positive +definition to a causality previously conceived only negatively, the +possibility of which was incomprehensible to speculative reason, which +yet was compelled to suppose it. For it adds the notion of a reason +that directly determines the will (by imposing on its maxims the +condition of a universal legislative form); and thus it is able for +the first time to give objective, though only practical, reality to +reason, which always became transcendent when it sought to proceed +speculatively with its ideas. It thus changes the transcendent use +of reason into an immanent use (so that reason is itself, by means +of ideas, an efficient cause in the field of experience). + +The determination of the causality of beings in the world of +sense, as such, can never be unconditioned; and yet for every series +of conditions there must be something unconditioned, and therefore +there must be a causality which is determined wholly by itself. Hence, +the idea of freedom as a faculty of absolute spontaneity was not found +to be a want but, as far as its possibility is concerned, an +analytic principle of pure speculative reason. But as it is absolutely +impossible to find in experience any example in accordance with this +idea, because amongst the causes of things as phenomena it would be +impossible to meet with any absolutely unconditioned determination +of causality, we were only able to defend our supposition that a +freely acting cause might be a being in the world of sense, in so +far as it is considered in the other point of view as a noumenon, +showing that there is no contradiction in regarding all its actions as +subject to physical conditions so far as they are phenomena, and yet +regarding its causality as physically unconditioned, in so far as +the acting being belongs to the world of understanding, and in thus +making the concept of freedom the regulative principle of reason. By +this principle I do not indeed learn what the object is to which +that sort of causality is attributed; but I remove the difficulty, +for, on the one side, in the explanation of events in the world, and +consequently also of the actions of rational beings, I leave to the +mechanism of physical necessity the right of ascending from +conditioned to condition ad infinitum, while on the other side I +keep open for speculative reason the place which for it is vacant, +namely, the intelligible, in order to transfer the unconditioned +thither. But I was not able to verify this supposition; that is, to +change it into the knowledge of a being so acting, not even into the +knowledge of the possibility of such a being. This vacant place is now +filled by pure practical reason with a definite law of causality in an +intelligible world (causality with freedom), namely, the moral law. +Speculative reason does not hereby gain anything as regards its +insight, but only as regards the certainty of its problematical notion +of freedom, which here obtains objective reality, which, though only +practical, is nevertheless undoubted. Even the notion of causality- +the application, and consequently the signification, of which holds +properly only in relation to phenomena, so as to connect them into +experiences (as is shown by the Critique of Pure Reason)- is not so +enlarged as to extend its use beyond these limits. For if reason +sought to do this, it would have to show how the logical relation of +principle and consequence can be used synthetically in a different +sort of intuition from the sensible; that is how a causa noumenon is +possible. This it can never do; and, as practical reason, it does +not even concern itself with it, since it only places the +determining principle of causality of man as a sensible creature +(which is given) in pure reason (which is therefore called practical); +and therefore it employs the notion of cause, not in order to know +objects, but to determine causality in relation to objects in general. +It can abstract altogether from the application of this notion to +objects with a view to theoretical knowledge (since this concept is +always found a priori in the understanding even independently of any +intuition). Reason, then, employs it only for a practical purpose, and +hence we can transfer the determining principle of the will into the +intelligible order of things, admitting, at the same time, that we +cannot understand how the notion of cause can determine the +knowledge of these things. But reason must cognise causality with +respect to the actions of the will in the sensible world in a definite +manner; otherwise, practical reason could not really produce any +action. But as to the notion which it forms of its own causality as +noumenon, it need not determine it theoretically with a view to the +cognition of its supersensible existence, so as to give it +significance in this way. For it acquires significance apart from +this, though only for practical use, namely, through the moral law. +Theoretically viewed, it remains always a pure a priori concept of the +understanding, which can be applied to objects whether they have +been given sensibly or not, although in the latter case it has no +definite theoretical significance or application, but is only a +formal, though essential, conception of the understanding relating +to an object in general. The significance which reason gives it +through the moral law is merely practical, inasmuch as the idea of +the law of causality (of the will) has self causality, or is +its determining principle. + + + +II. Of the Right that Pure Reason in its Practical use has to an +Extension which is not possible to it in its Speculative Use. + + {BOOK_1|CHAPTER_1 ^paragraph 145} + + + +We have in the moral principle set forth a law of causality, the +determining principle of which is set above all the conditions of +the sensible world; we have it conceived how the will, as belonging +to the intelligible world, is determinable, and therefore have +its subject (man) not merely conceived as belonging to a world of +pure understanding, and in this respect unknown (which the critique of +speculative reason enabled us to do), but also defined as regards +his causality by means of a law which cannot be reduced to any +physical law of the sensible world; and therefore our knowledge is +extended beyond the limits of that world, a pretension which the +Critique of Pure Reason declared to be futile in all speculation. Now, +how is the practical use of pure reason here to be reconciled with the +theoretical, as to the determination of the limits of its faculty? + +David Hume, of whom we may say that he commenced the assault on +the claims of pure reason, which made a thorough investigation of it +necessary, argued thus: The notion of cause is a notion that +involves the necessity of the connexion of the existence of +different things (and that, in so far as they are different), so that, +given A, I know that something quite distinct there from, namely B, +must necessarily also exist. Now necessity can be attributed to a +connection, only in so far as it is known a priori, for experience +would only enable us to know of such a connection that it exists, +not that it necessarily exists. Now, it is impossible, says he, to +know a priori and as necessary the connection between one thing and +another (or between one attribute and another quite distinct) when +they have not been given in experience. Therefore the notion of a +cause is fictitious and delusive and, to speak in the mildest way, +is an illusion, only excusable inasmuch as the custom (a subjective +necessity) of perceiving certain things, or their attributes as +often associated in existence along with or in succession to one +another, is insensibly taken for an objective necessity of supposing +such a connection in the objects themselves; and thus the notion of +a cause has been acquired surreptitiously and not legitimately; nay, +it can never be so acquired or authenticated, since it demands a +connection in itself vain, chimerical, and untenable in presence of +reason, and to which no object can ever correspond. In this way was +empiricism first introduced as the sole source of principles, as far +as all knowledge of the existence of things is concerned +(mathematics therefore remaining excepted); and with empiricism the +most thorough scepticism, even with regard to the whole science of +nature( as philosophy). For on such principles we can never conclude +from given attributes of things as existing to a consequence (for this +would require the notion of cause, which involves the necessity of +such a connection); we can only, guided by imagination, expect similar +cases- an expectation which is never certain, however often it has +been fulfilled. Of no event could we say: a certain thing must have +preceded it, on which it necessarily followed; that is, it must have a +cause; and therefore, however frequent the cases we have known in +which there was such an antecedent, so that a rule could be derived +from them, yet we never could suppose it as always and necessarily +so happening; we should, therefore, be obliged to leave its share to +blind chance, with which all use of reason comes to an end; and this +firmly establishes scepticism in reference to arguments ascending from +effects to causes and makes it impregnable. + +Mathematics escaped well, so far, because Hume thought that its +propositions were analytical; that is, proceeded from one property +to another, by virtue of identity and, consequently, according to +the principle of contradiction. This, however, is not the case, since, +on the contrary, they are synthetical; and although geometry, for +example, has not to do with the existence of things, but only with +their a priori properties in a possible intuition, yet it proceeds +just as in the case of the causal notion, from one property (A) to +another wholly distinct (B), as necessarily connected with the former. +Nevertheless, mathematical science, so highly vaunted for its +apodeictic certainty, must at last fall under this empiricism for +the same reason for which Hume put custom in the place of objective +necessity in the notion of cause and, in spite of all its pride, +must consent to lower its bold pretension of claiming assent a +priori and depend for assent to the universality of its propositions +on the kindness of observers, who, when called as witnesses, would +surely not hesitate to admit that what the geometer propounds as a +theorem they have always perceived to be the fact, and, +consequently, although it be not necessarily true, yet they would +permit us to expect it to be true in the future. In this manner Hume's +empiricism leads inevitably to scepticism, even with regard to +mathematics, and consequently in every scientific theoretical use of +reason (for this belongs either to philosophy or mathematics). Whether +with such a terrible overthrow of the chief branches of knowledge, +common reason will escape better, and will not rather become +irrecoverably involved in this destruction of all knowledge, so that +from the same principles a universal scepticism should follow +(affecting, indeed, only the learned), this I will leave everyone to +judge for himself. + +As regards my own labours in the critical examination of pure +reason, which were occasioned by Hume's sceptical teaching, but went +much further and embraced the whole field of pure theoretical reason +in its synthetic use and, consequently, the field of what is called +metaphysics in general; I proceeded in the following manner with +respect to the doubts raised by the Scottish philosopher touching +the notion of causality. If Hume took the objects of experience for +things in themselves (as is almost always done), he was quite right in +declaring the notion of cause to be a deception and false illusion; +for as to things in themselves, and their attributes as such, it is +impossible to see why because A is given, B, which is different, +must necessarily be also given, and therefore he could by no means +admit such an a priori knowledge of things in themselves. Still less +could this acute writer allow an empirical origin of this concept, +since this is directly contradictory to the necessity of connection +which constitutes the essence of the notion of causality, hence the +notion was proscribed, and in its place was put custom in the +observation of the course of perceptions. + + {BOOK_1|CHAPTER_1 ^paragraph 150} + +It resulted, however, from my inquiries, that the objects with which +we have to do in experience are by no means things in themselves, +but merely phenomena; and that although in the case of things in +themselves it is impossible to see how, if A is supposed, it should be +contradictory that B, which is quite different from A, should not also +be supposed (i.e., to see the necessity of the connection between A as +cause and B as effect); yet it can very well be conceived that, as +phenomena, they may be necessarily connected in one experience in a +certain way (e.g., with regard to time-relations); so that they +could not be separated without contradicting that connection, by means +of which this experience is possible in which they are objects and +in which alone they are cognisable by us. And so it was found to be in +fact; so that I was able not only to prove the objective reality of +the concept of cause in regard to objects of experience, but also to +deduce it as an a priori concept by reason of the necessity of the +connection it implied; that is, to show the possibility of its +origin from pure understanding without any empirical sources; and +thus, after removing the source of empiricism, I was able also to +overthrow the inevitable consequence of this, namely, scepticism, +first with regard to physical science, and then with regard to +mathematics (in which empiricism has just the same grounds), both +being sciences which have reference to objects of possible experience; +herewith overthrowing the thorough doubt of whatever theoretic +reason professes to discern. + +But how is it with the application of this category of causality +(and all the others; for without them there can be no knowledge of +anything existing) to things which are not objects of possible +experience, but lie beyond its bounds? For I was able to deduce the +objective reality of these concepts only with regard to objects of +possible experience. But even this very fact, that I have saved +them, only in case I have proved that objects may by means of them +be thought, though not determined a priori; this it is that gives them +a place in the pure understanding, by which they are referred to +objects in general (sensible or not sensible). If anything is still +wanting, it is that which is the condition of the application of these +categories, and especially that of causality, to objects, namely, +intuition; for where this is not given, the application with a view to +theoretic knowledge of the object, as a noumenon, is impossible and, +therefore, if anyone ventures on it, is (as in the Critique of Pure +Reason) absolutely forbidden. Still, the objective reality of the +concept (of causality) remains, and it can be used even of noumena, +but without our being able in the least to define the concept +theoretically so as to produce knowledge. For that this concept, +even in reference to an object, contains nothing impossible, was shown +by this, that, even while applied to objects of sense, its seat was +certainly fixed in the pure understanding; and although, when referred +to things in themselves (which cannot be objects of experience), it is +not capable of being determined so as to represent a definite object +for the purpose of theoretic knowledge; yet for any other purpose (for +instance, a practical) it might be capable of being determined so as +to have such application. This could not be the case if, as Hume +maintained, this concept of causality contained something absolutely +impossible to be thought. + +In order now to discover this condition of the application of the +said concept to noumena, we need only recall why we are not content +with its application to objects of experience, but desire also to +apply it to things in themselves. It will appear, then, that it is not +a theoretic but a practical purpose that makes this a necessity. In +speculation, even if we were successful in it, we should not really +gain anything in the knowledge of nature, or generally with regard +to such objects as are given, but we should make a wide step from +the sensibly conditioned (in which we have already enough to do to +maintain ourselves, and to follow carefully the chain of causes) to +the supersensible, in order to complete our knowledge of principles +and to fix its limits; whereas there always remains an infinite +chasm unfilled between those limits and what we know; and we should +have hearkened to a vain curiosity rather than a solid-desire of +knowledge. + +But, besides the relation in which the understanding stands to +objects (in theoretical knowledge), it has also a relation to the +faculty of desire, which is therefore called the will, and the pure +will, inasmuch as pure understanding (in this case called reason) is +practical through the mere conception of a law. The objective +reality of a pure will, or, what is the same thing, of a pure +practical reason, is given in the moral law a priori, as it were, by a +fact, for so we may name a determination of the will which is +inevitable, although it does not rest on empirical principles. Now, in +the notion of a will the notion of causality is already contained, and +hence the notion of a pure will contains that of a causality +accompanied with freedom, that is, one which is not determinable by +physical laws, and consequently is not capable of any empirical +intuition in proof of its reality, but, nevertheless, completely +justifies its objective reality a priori in the pure practical law; +not, indeed (as is easily seen) for the purposes of the theoretical, +but of the practical use of reason. Now the notion of a being that has +free will is the notion of a causa noumenon, and that this notion +involves no contradiction, we are already assured by the fact- that +inasmuch as the concept of cause has arisen wholly from pure +understanding, and has its objective reality assured by the deduction, +as it is moreover in its origin independent of any sensible +conditions, it is, therefore, not restricted to phenomena (unless we +wanted to make a definite theoretic use of it), but can be applied +equally to things that are objects of the pure understanding. But, +since this application cannot rest on any intuition (for intuition can +only be sensible), therefore, causa noumenon, as regards the theoretic +use of reason, although a possible and thinkable, is yet an empty +notion. Now, I do not desire by means of this to understand +theoretically the nature of a being, in so far as it has a pure +will; it is enough for me to have thereby designated it as such, and +hence to combine the notion of causality with that of freedom (and +what is inseparable from it, the moral law, as its determining +principle). Now, this right I certainly have by virtue of the pure, +not-empirical origin of the notion of cause, since I do not consider +myself entitled to make any use of it except in reference to the moral +law which determines its reality, that is, only a practical use. + +If, with Hume, I had denied to the notion of causality all objective +reality in its [theoretic] use, not merely with regard to things in +themselves (the supersensible), but also with regard to the objects of +the senses, it would have lost all significance, and being a +theoretically impossible notion would have been declared to be quite +useless; and since what is nothing cannot be made any use of, the +practical use of a concept theoretically null would have been +absurd. But, as it is, the concept of a causality free from +empirical conditions, although empty, i.e., without any appropriate +intuition), is yet theoretically possible, and refers to an +indeterminate object; but in compensation significance is given to +it in the moral law and consequently in a practical sense. I have, +indeed, no intuition which should determine its objective theoretic +reality, but not the less it has a real application, which is +exhibited in concreto in intentions or maxims; that is, it has a +practical reality which can be specified, and this is sufficient to +justify it even with a view to noumena. + + {BOOK_1|CHAPTER_1 ^paragraph 155} + +Now, this objective reality of a pure concept of the understanding +in the sphere of the supersensible, once brought in, gives an +objective reality also to all the other categories, although only so +far as they stand in necessary connexion with the determining +principle of the will (the moral law); a reality only of practical +application, which has not the least effect in enlarging our +theoretical knowledge of these objects, or the discernment of their +nature by pure reason. So we shall find also in the sequel that +these categories refer only to beings as intelligences, and in them +only to the relation of reason to the will; consequently, always +only to the practical, and beyond this cannot pretend to any knowledge +of these beings; and whatever other properties belonging to the +theoretical representation of supersensible things may be brought into +connexion with these categories, this is not to be reckoned as +knowledge, but only as a right (in a practical point of view, however, +it is a necessity) to admit and assume such beings, even in the case +where we [conceive] supersensible beings (e.g., God) according to +analogy, that is, a purely rational relation, of which we make a +practical use with reference to what is sensible; and thus the +application to the supersensible solely in a practical point of view +does not give pure theoretic reason the least encouragement to run +riot into the transcendent. + +BOOK_1|CHAPTER_2 + +CHAPTER II. Of the Concept of an Object of Pure Practical Reason. + + + +By a concept of the practical reason I understand the idea of an +object as an effect possible to be produced through freedom. To be +an object of practical knowledge, as such, signifies, therefore, +only the relation of the will to the action by which the object or its +opposite would be realized; and to decide whether something is an +object of pure practical reason or not is only to discern the +possibility or impossibility of willing the action by which, if we had +the required power (about which experience must decide), a certain +object would be realized. If the object be taken as the determining +principle of our desire, it must first be known whether it is +physically possible by the free use of our powers, before we decide +whether it is an object of practical reason or not. On the other hand, +if the law can be considered a priori as the determining principle +of the action, and the latter therefore as determined by pure +practical reason, the judgement whether a thing is an object of pure +practical reason or not does not depend at all on the comparison +with our physical power; and the question is only whether we should +will an action that is directed to the existence of an object, if +the object were in our power; hence the previous question is only as +the moral possibility of the action, for in this case it is not the +object, but the law of the will, that is the determining principle +of the action. The only objects of practical reason are therefore +those of good and evil. For by the former is meant an object +necessarily desired according to a principle of reason; by the +latter one necessarily shunned, also according to a principle of +reason. + +If the notion of good is not to be derived from an antecedent +practical law, but, on the contrary, is to serve as its foundation, it +can only be the notion of something whose existence promises pleasure, +and thus determines the causality of the subject to produce it, that +is to say, determines the faculty of desire. Now, since it is +impossible to discern a priori what idea will be accompanied with +pleasure and what with pain, it will depend on experience alone to +find out what is primarily good or evil. The property of the +subject, with reference to which alone this experiment can be made, is +the feeling of pleasure and pain, a receptivity belonging to the +internal sense; thus that only would be primarily good with which +the sensation of pleasure is immediately connected, and that simply +evil which immediately excites pain. Since, however, this is opposed +even to the usage of language, which distinguishes the pleasant from +the good, the unpleasant from the evil, and requires that good and +evil shall always be judged by reason, and, therefore, by concepts +which can be communicated to everyone, and not by mere sensation, +which is limited to individual [subjects] and their susceptibility; +and, since nevertheless, pleasure or pain cannot be connected with any +idea of an object a priori, the philosopher who thought himself +obliged to make a feeling of pleasure the foundation of his +practical judgements would call that good which is a means to the +pleasant, and evil, what is a cause of unpleasantness and pain; for +the judgement on the relation of means to ends certainly belongs to +reason. But, although reason is alone capable of discerning the +connexion of means with their ends (so that the will might even be +defined as the faculty of ends, since these are always determining +principles of the desires), yet the practical maxims which would +follow from the aforesaid principle of the good being merely a +means, would never contain as the object of the will anything good +in itself, but only something good for something; the good would +always be merely the useful, and that for which it is useful must +always lie outside the will, in sensation. Now if this as a pleasant +sensation were to be distinguished from the notion of good, then there +would be nothing primarily good at all, but the good would have to +be sought only in the means to something else, namely, some +pleasantness. + +It is an old formula of the schools: Nihil appetimus nisi sub +ratione boni; Nihil aversamur nisi sub ratione mali, and it is used +often correctly, but often also in a manner injurious to philosophy, +because the expressions boni and mali are ambiguous, owing to the +poverty of language, in consequence of which they admit a double +sense, and, therefore, inevitably bring the practical laws into +ambiguity; and philosophy, which in employing them becomes aware of +the different meanings in the same word, but can find no special +expressions for them, is driven to subtile distinctions about which +there is subsequently no unanimity, because the distinction could +not be directly marked by any suitable expression. * + + + +* Besides this, the expression sub ratione boni is also ambiguous. +For it may mean: "We represent something to ourselves as good, when +and because we desire (will) it"; or "We desire something because we +represent it to ourselves as good," so that either the desire +determines the notion of the object as a good, or the notion of good +determines the desire (the will); so that in the first case sub +ratione boni would mean, "We will something under the idea of the +good"; in the second, "In consequence of this idea," which, as +determining the volition, must precede it. + + {BOOK_1|CHAPTER_2 ^paragraph 5} + + + +The German language has the good fortune to possess expressions +which do not allow this difference to be overlooked. It possesses +two very distinct concepts and especially distinct expressions for +that which the Latins express by a single word, bonum. For bonum it +has das Gute [good], and das Wohl [well, weal], for malum das Bose +[evil], and das Ubel [ill, bad], or das Well [woe]. So that we express +two quite distinct judgements when we consider in an action the good +and evil of it, or our weal and woe (ill). Hence it already follows +that the above quoted psychological proposition is at least very +doubtful if it is translated: "We desire nothing except with a view to +our weal or woe"; on the other hand, if we render it thus: "Under +the direction of reason we desire nothing except so far as we esteem +it good or evil," it is indubitably certain and at the same time quite +clearly expressed. + +Well or ill always implies only a reference to our condition, as +pleasant or unpleasant, as one of pleasure or pain, and if we desire +or avoid an object on this account, it is only so far as it is +referred to our sensibility and to the feeling of pleasure or pain +that it produces. But good or evil always implies a reference to the +will, as determined by the law of reason, to make something its +object; for it is never determined directly by the object and the idea +of it, but is a faculty of taking a rule of reason for or motive of an +action (by which an object may be realized). Good and evil therefore +are properly referred to actions, not to the sensations of the person, +and if anything is to be good or evil absolutely (i.e., in every +respect and without any further condition), or is to be so esteemed, +it can only be the manner of acting, the maxim of the will, and +consequently the acting person himself as a good or evil man that +can be so called, and not a thing. + +However, then, men may laugh at the Stoic, who in the severest +paroxysms of gout cried out: "Pain, however thou tormentest me, I will +never admit that thou art an evil (kakov, malum)": he was right. A bad +thing it certainly was, and his cry betrayed that; but that any evil +attached to him thereby, this he had no reason whatever to admit, +for pain did not in the least diminish the worth of his person, but +only that of his condition. If he had been conscious of a single +lie, it would have lowered his pride, but pain served only to raise +it, when he was conscious that he had not deserved it by any +unrighteous action by which he had rendered himself worthy of +punishment. + +What we call good must be an object of desire in the judgement of +every rational man, and evil an object of aversion in the eyes of +everyone; therefore, in addition to sense, this judgement requires +reason. So it is with truthfulness, as opposed to lying; so with +justice, as opposed to violence, &c. But we may call a thing a bad [or +ill] thing, which yet everyone must at the same time acknowledge to be +good, sometimes directly, sometimes indirectly. The man who submits to +a surgical operation feels it no doubt as a bad thing, but by their +reason he and everyone acknowledge it to be good. If a man who +delights in annoying and vexing peaceable people at last receives a +right good beating, this is no doubt a bad thing; but everyone +approves it and regards it as a good thing, even though nothing else +resulted from it; nay, even the man who receives it must in his reason +acknowledge that he has met justice, because he sees the proportion +between good conduct and good fortune, which reason inevitably +places before him, here put into practice. + + {BOOK_1|CHAPTER_2 ^paragraph 10} + +No doubt our weal and woe are of very great importance in the +estimation of our practical reason, and as far as our nature as +sensible beings is concerned, our happiness is the only thing of +consequence, provided it is estimated as reason especially requires, +not by the transitory sensation, but by the influence that this has on +our whole existence, and on our satisfaction therewith; but it is +not absolutely the only thing of consequence. Man is a being who, as +belonging to the world of sense, has wants, and so far his reason +has an office which it cannot refuse, namely, to attend to the +interest of his sensible nature, and to form practical maxims, even +with a view to the happiness of this life, and if possible even to +that of a future. But he is not so completely an animal as to be +indifferent to what reason says on its own account, and to use it +merely as an instrument for the satisfaction of his wants as a +sensible being. For the possession of reason would not raise his worth +above that of the brutes, if it is to serve him only for the same +purpose that instinct serves in them; it would in that case be only +a particular method which nature had employed to equip man for the +same ends for which it has qualified brutes, without qualifying him +for any higher purpose. No doubt once this arrangement of nature has +been made for him he requires reason in order to take into +consideration his weal and woe, but besides this he possesses it for a +higher purpose also, namely, not only to take into consideration +what is good or evil in itself, about which only pure reason, +uninfluenced by any sensible interest, can judge, but also to +distinguish this estimate thoroughly from the former and to make it +the supreme condition thereof. + +In estimating what is good or evil in itself, as distinguished +from what can be so called only relatively, the following points are +to be considered. Either a rational principle is already conceived, as +of itself the determining principle of the will, without regard to +possible objects of desire (and therefore by the more legislative form +of the maxim), and in that case that principle is a practical a priori +law, and pure reason is supposed to be practical of itself. The law in +that case determines the will directly; the action conformed to it +is good in itself; a will whose maxim always conforms to this law is +good absolutely in every respect and is the supreme condition of all +good. Or the maxim of the will is consequent on a determining +principle of desire which presupposes an object of pleasure or pain, +something therefore that pleases or displeases, and the maxim of +reason that we should pursue the former and avoid the latter +determines our actions as good relatively to our inclination, that is, +good indirectly, (i.e., relatively to a different end to which they are +means), and in that case these maxims can never be called laws, but +may be called rational practical precepts. The end itself, the +pleasure that we seek, is in the latter case not a good but a welfare; +not a concept of reason, but an empirical concept of an object of +sensation; but the use of the means thereto, that is, the action, is +nevertheless called good (because rational deliberation is required +for it), not however, good absolutely, but only relatively to our +sensuous nature, with regard to its feelings of pleasure and +displeasure; but the will whose maxim is affected thereby is not a +pure will; this is directed only to that in which pure reason by +itself can be practical. + +This is the proper place to explain the paradox of method in a +critique of practical reason, namely, that the concept of good and +evil must not be determined before the moral law (of which it seems as +if it must be the foundation), but only after it and by means of it. +In fact, even if we did not know that the principle of morality is a +pure a priori law determining the will, yet, that we may not assume +principles quite gratuitously, we must, at least at first, leave it +undecided, whether the will has merely empirical principles of +determination, or whether it has not also pure a priori principles; +for it is contrary to all rules of philosophical method to assume as +decided that which is the very point in question. Supposing that we +wished to begin with the concept of good, in order to deduce from it +the laws of the will, then this concept of an object (as a good) would +at the same time assign to us this object as the sole determining +principle of the will. Now, since this concept had not any practical a +priori law for its standard, the criterion of good or evil could not +be placed in anything but the agreement of the object with our feeling +of pleasure or pain; and the use of reason could only consist in +determining in the first place this pleasure or pain in connexion with +all the sensations of my existence, and in the second place the +means of securing to myself the object of the pleasure. Now, as +experience alone can decide what conforms to the feeling of +pleasure, and by hypothesis the practical law is to be based on this +as a condition, it follows that the possibility of a priori +practical laws would be at once excluded, because it was imagined to +be necessary first of all to find an object the concept of which, as a +good, should constitute the universal though empirical principle of +determination of the will. But what it was necessary to inquire +first of all was whether there is not an a priori determining +principle of the will (and this could never be found anywhere but in a +pure practical law, in so far as this law prescribes to maxims +merely their form without regard to an object). Since, however, we +laid the foundation of all practical law in an object determined by +our conceptions of good and evil, whereas without a previous law +that object could not be conceived by empirical concepts, we have +deprived ourselves beforehand of the possibility of even conceiving +a pure practical law. On the other hand, if we had first +investigated the latter analytically, we should have found that it +is not the concept of good as an object that determines the moral +law and makes it possible, but that, on the contrary, it is the +moral law that first determines the concept of good and makes it +possible, so far as it deserves the name of good absolutely. + +This remark, which only concerns the method of ultimate ethical +inquiries, is of importance. It explains at once the occasion of all +the mistakes of philosophers with respect to the supreme principle +of morals. For they sought for an object of the will which they +could make the matter and principle of a law (which consequently could +not determine the will directly, but by means of that object +referred to the feeling of pleasure or pain; whereas they ought +first to have searched for a law that would determine the will a +priori and directly, and afterwards determine the object in accordance +with the will). Now, whether they placed this object of pleasure, +which was to supply the supreme conception of goodness, in +happiness, in perfection, in moral [feeling], or in the will of God, +their principle in every case implied heteronomy, and they must +inevitably come upon empirical conditions of a moral law, since +their object, which was to be the immediate principle of the will, +could not be called good or bad except in its immediate relation to +feeling, which is always empirical. It is only a formal law- that +is, one which prescribes to reason nothing more than the form of its +universal legislation as the supreme condition of its maxims- that can +be a priori a determining principle of practical reason. The +ancients avowed this error without concealment by directing all +their moral inquiries to the determination of the notion of the summum +bonum, which they intended afterwards to make the determining +principle of the will in the moral law; whereas it is only far +later, when the moral law has been first established for itself, and +shown to be the direct determining principle of the will, that this +object can be presented to the will, whose form is now determined a +priori; and this we shall undertake in the Dialectic of the pure +practical reason. The moderns, with whom the question of the summum +bonum has gone out of fashion, or at least seems to have become a +secondary matter, hide the same error under vague (expressions as in +many other cases). It shows itself, nevertheless, in their systems, as +it always produces heteronomy of practical reason; and from this can +never be derived a moral law giving universal commands. + +Now, since the notions of good and evil, as consequences of the a +priori determination of the will, imply also a pure practical +principle, and therefore a causality of pure reason; hence they do not +originally refer to objects (so as to be, for instance, special +modes of the synthetic unity of the manifold of given intuitions in +one consciousness) like the pure concepts of the understanding or +categories of reason in its theoretic employment; on the contrary, +they presuppose that objects are given; but they are all modes +(modi) of a single category, namely, that of causality, the +determining principle of which consists in the rational conception +of a law, which as a law of freedom reason gives to itself, thereby +a priori proving itself practical. However, as the actions on the +one side come under a law which is not a physical law, but a law of +freedom, and consequently belong to the conduct of beings in the world +of intelligence, yet on the other side as events in the world of sense +they belong to phenomena; hence the determinations of a practical +reason are only possible in reference to the latter and, therefore, in +accordance with the categories of the understanding; not indeed with a +view to any theoretic employment of it, i.e., so as to bring the +manifold of (sensible) intuition under one consciousness a priori; but +only to subject the manifold of desires to the unity of +consciousness of a practical reason, giving it commands in the moral +law, i.e., to a pure will a priori. + + {BOOK_1|CHAPTER_2 ^paragraph 15} + +These categories of freedom- for so we choose to call them in +contrast to those theoretic categories which are categories of +physical nature- have an obvious advantage over the latter, inasmuch +as the latter are only forms of thought which designate objects in +an indefinite manner by means of universal concept of every possible +intuition; the former, on the contrary, refer to the determination +of a free elective will (to which indeed no exactly corresponding +intuition can be assigned, but which has as its foundation a pure +practical a priori law, which is not the case with any concepts +belonging to the theoretic use of our cognitive faculties); hence, +instead of the form of intuition (space and time), which does not +lie in reason itself, but has to be drawn from another source, namely, +the sensibility, these being elementary practical concepts have as +their foundation the form of a pure will, which is given in reason +and, therefore, in the thinking faculty itself. From this it happens +that as all precepts of pure practical reason have to do only with the +determination of the will, not with the physical conditions (of +practical ability) of the execution of one's purpose, the practical +a priori principles in relation to the supreme principle of freedom +are at once cognitions, and have not to wait for intuitions in order +to acquire significance, and that for this remarkable reason, +because they themselves produce the reality of that to which they +refer (the intention of the will), which is not the case with +theoretical concepts. Only we must be careful to observe that these +categories only apply to the practical reason; and thus they proceed +in order from those which are as yet subject to sensible conditions +and morally indeterminate to those which are free from sensible +conditions and determined merely by the moral law. + + + +Table of the Categories of Freedom relatively to the Notions of Good +and Evil. + + + + I.

These can be established dogmatically only +by the moral law. + +I add nothing further here in explanation of the present table, +since it is intelligible enough of itself. A division of this kind +based on principles is very useful in any science, both for the sake +of thoroughness and intelligibility. Thus, for instance, we know +from the preceding table and its first number what we must begin +from in practical inquiries; namely, from the maxims which every one +founds on his own inclinations; the precepts which hold for a +species of rational beings so far as they agree in certain +inclinations; and finally the law which holds for all without regard +to their inclinations, etc. In this way we survey the whole plan of +what has to be done, every question of practical philosophy that has +to be answered, and also the order that is to be followed. + + + +Of the Typic of the Pure Practical Judgement. + + + + {BOOK_1|CHAPTER_2 ^paragraph 45} + +It is the notions of good and evil that first determine an object of +the will. They themselves, however, are subject to a practical rule of +reason which, if it is pure reason, determines the will a priori +relatively to its object. Now, whether an action which is possible +to us in the world of sense, comes under the rule or not, is a +question to be decided by the practical judgement, by which what is +said in the rule universally (in abstracto) is applied to an action in +concreto. But since a practical rule of pure reason in the first place +as practical concerns the existence of an object, and in the second +place as a practical rule of pure reason implies necessity as +regards the existence of the action and, therefore, is a practical +law, not a physical law depending on empirical principles of +determination, but a law of freedom by which the will is to be +determined independently on anything empirical (merely by the +conception of a law and its form), whereas all instances that can +occur of possible actions can only be empirical, that is, belong to +the experience of physical nature; hence, it seems absurd to expect to +find in the world of sense a case which, while as such it depends only +on the law of nature, yet admits of the application to it of a law +of freedom, and to which we can apply the supersensible idea of the +morally good which is to be exhibited in it in concreto. Thus, the +judgement of the pure practical reason is subject to the same +difficulties as that of the pure theoretical reason. The latter, +however, had means at hand of escaping from these difficulties, +because, in regard to the theoretical employment, intuitions were +required to which pure concepts of the understanding could be applied, +and such intuitions (though only of objects of the senses) can be +given a priori and, therefore, as far as regards the union of the +manifold in them, conforming to the pure a priori concepts of the +understanding as schemata. On the other hand, the morally good is +something whose object is supersensible; for which, therefore, nothing +corresponding can be found in any sensible intuition. Judgement +depending on laws of pure practical reason seems, therefore, to be +subject to special difficulties arising from this, that a law of +freedom is to be applied to actions, which are events taking place +in the world of sense, and which, so far, belong to physical nature. + +But here again is opened a favourable prospect for the pure +practical judgement. When I subsume under a pure practical law an +action possible to me in the world of sense, I am not concerned with +the possibility of the action as an event in the world of sense. +This is a matter that belongs to the decision of reason in its +theoretic use according to the law of causality, which is a pure +concept of the understanding, for which reason has a schema in the +sensible intuition. Physical causality, or the condition under which +it takes place, belongs to the physical concepts, the schema of +which is sketched by transcendental imagination. Here, however, we +have to do, not with the schema of a case that occurs according to +laws, but with the schema of a law itself (if the word is allowable +here), since the fact that the will (not the action relatively to +its effect) is determined by the law alone without any other +principle, connects the notion of causality with quite different +conditions from those which constitute physical connection. + +The physical law being a law to which the objects of sensible +intuition, as such, are subject, must have a schema corresponding to +it- that is, a general procedure of the imagination (by which it +exhibits a priori to the senses the pure concept of the +understanding which the law determines). But the law of freedom +(that is, of a causality not subject to sensible conditions), and +consequently the concept of the unconditionally good, cannot have +any intuition, nor consequently any schema supplied to it for the +purpose of its application in concreto. Consequently the moral law has +no faculty but the understanding to aid its application to physical +objects (not the imagination); and the understanding for the +purposes of the judgement can provide for an idea of the reason, not a +schema of the sensibility, but a law, though only as to its form as +law; such a law, however, as can be exhibited in concreto in objects +of the senses, and therefore a law of nature. We can therefore call +this law the type of the moral law. + +The rule of the judgement according to laws of pure practical reason +is this: ask yourself whether, if the action you propose were to +take place by a law of the system of nature of which you were yourself +a part, you could regard it as possible by your own will. Everyone +does, in fact, decide by this rule whether actions are morally good or +evil. Thus, people say: "If everyone permitted himself to deceive, +when he thought it to his advantage; or thought himself justified in +shortening his life as soon as he was thoroughly weary of it; or +looked with perfect indifference on the necessity of others; and if +you belonged to such an order of things, would you do so with the +assent of your own will?" Now everyone knows well that if he +secretly allows himself to deceive, it does not follow that everyone +else does so; or if, unobserved, he is destitute of compassion, others +would not necessarily be so to him; hence, this comparison of the +maxim of his actions with a universal law of nature is not the +determining principle of his will. Such a law is, nevertheless, a type +of the estimation of the maxim on moral principles. If the maxim of +the action is not such as to stand the test of the form of a universal +law of nature, then it is morally impossible. This is the judgement +even of common sense; for its ordinary judgements, even those of +experience, are always based on the law of nature. It has it therefore +always at hand, only that in cases where causality from freedom is +to be criticised, it makes that law of nature only the type of a law +of freedom, because, without something which it could use as an +example in a case of experience, it could not give the law of a pure +practical reason its proper use in practice. + +It is therefore allowable to use the system of the world of sense as +the type of a supersensible system of things, provided I do not +transfer to the latter the intuitions, and what depends on them, but +merely apply to it the form of law in general (the notion of which +occurs even in the commonest use of reason, but cannot be definitely +known a priori for any other purpose than the pure practical use of +reason); for laws, as such, are so far identical, no matter from +what they derive their determining principles. + + {BOOK_1|CHAPTER_2 ^paragraph 50} + +Further, since of all the supersensible absolutely nothing [is +known] except freedom (through the moral law), and this only so far as +it is inseparably implied in that law, and moreover all +supersensible objects to which reason might lead us, following the +guidance of that law, have still no reality for us, except for the +purpose of that law, and for the use of mere practical reason; and +as reason is authorized and even compelled to use physical nature +(in its pure form as an object of the understanding) as the type of +the judgement; hence, the present remark will serve to guard against +reckoning amongst concepts themselves that which belongs only to the +typic of concepts. This, namely, as a typic of the judgement, guards +against the empiricism of practical reason, which founds the practical +notions of good and evil merely on experienced consequences (so-called +happiness). No doubt happiness and the infinite advantages which would +result from a will determined by self-love, if this will at the same +time erected itself into a universal law of nature, may certainly +serve as a perfectly suitable type of the morally good, but it is +not identical with it. The same typic guards also against the +mysticism of practical reason, which turns what served only as a +symbol into a schema, that is, proposes to provide for the moral +concepts actual intuitions, which, however, are not sensible +(intuitions of an invisible Kingdom of God), and thus plunges into the +transcendent. What is befitting the use of the moral concepts is +only the rationalism of the judgement, which takes from the sensible +system of nature only what pure reason can also conceive of itself, +that is, conformity to law, and transfers into the supersensible +nothing but what can conversely be actually exhibited by actions in +the world of sense according to the formal rule of a law of nature. +However, the caution against empiricism of practical reason is much +more important; for mysticism is quite reconcilable with the purity +and sublimity of the moral law, and, besides, it is not very natural +or agreeable to common habits of thought to strain one's imagination +to supersensible intuitions; and hence the danger on this side is +not so general. Empiricism, on the contrary, cuts up at the roots +the morality of intentions (in which, and not in actions only, +consists the high worth that men can and ought to give to themselves), +and substitutes for duty something quite different, namely, an +empirical interest, with which the inclinations generally are secretly +leagued; and empiricism, moreover, being on this account allied with +all the inclinations which (no matter what fashion they put on) +degrade humanity when they are raised to the dignity of a supreme +practical principle; and as these, nevertheless, are so favourable +to everyone's feelings, it is for that reason much more dangerous than +mysticism, which can never constitute a lasting condition of any great +number of persons. + +BOOK_1|CHAPTER_3 + + CHAPTER III. Of the Motives of Pure Practical Reason. + + + +What is essential in the moral worth of actions is that the moral +law should directly determine the will. If the determination of the +will takes place in conformity indeed to the moral law, but only by +means of a feeling, no matter of what kind, which has to be +presupposed in order that the law may be sufficient to determine the +will, and therefore not for the sake of the law, then the action +will possess legality, but not morality. Now, if we understand by +motive (elater animi) the subjective ground of determination of the +will of a being whose reason does not necessarily conform to the +objective law, by virtue of its own nature, then it will follow, +first, that no motives can be attributed to the Divine will, and that +the motives of the human will (as well as that of every created +rational being) can never be anything else than the moral law, and +consequently that the objective principle of determination must always +and alone be also the subjectively sufficient determining principle of +the action, if this is not merely to fulfil the letter of the law, +without containing its spirit. * + + + +* We may say of every action that conforms to the law, but is not +done for the sake of the law, that it is morally good in the letter, +not in the spirit (the intention). + + + +Since, then, for the purpose of giving the moral law influence +over the will, we must not seek for any other motives that might +enable us to dispense with the motive of the law itself, because +that would produce mere hypocrisy, without consistency; and it is even +dangerous to allow other motives (for instance, that of interest) even +to co-operate along with the moral law; hence nothing is left us but +to determine carefully in what way the moral law becomes a motive, and +what effect this has upon the faculty of desire. For as to the +question how a law can be directly and of itself a determining +principle of the will (which is the essence of morality), this is, for +human reason, an insoluble problem and identical with the question: +how a free will is possible. Therefore what we have to show a priori +is not why the moral law in itself supplies a motive, but what +effect it, as such, produces (or, more correctly speaking, must +produce) on the mind. + + {BOOK_1|CHAPTER_3 ^paragraph 5} + +The essential point in every determination of the will by the +moral law is that being a free will it is determined simply by the +moral law, not only without the co-operation of sensible impulses, but +even to the rejection of all such, and to the checking of all +inclinations so far as they might be opposed to that law. So far, +then, the effect of the moral law as a motive is only negative, and +this motive can be known a priori to be such. For all inclination +and every sensible impulse is founded on feeling, and the negative +effect produced on feeling (by the check on the inclinations) is +itself feeling; consequently, we can see a priori that the moral +law, as a determining principle of the will, must by thwarting all our +inclinations produce a feeling which may be called pain; and in this +we have the first, perhaps the only, instance in which we are able +from a priori considerations to determine the relation of a +cognition (in this case of pure practical reason) to the feeling of +pleasure or displeasure. All the inclinations together (which can be +reduced to a tolerable system, in which case their satisfaction is +called happiness) constitute self-regard (solipsismus). This is either +the self-love that consists in an excessive fondness for oneself +(philautia), or satisfaction with oneself (arrogantia). The former +is called particularly selfishness; the latter self-conceit. Pure +practical reason only checks selfishness, looking on it as natural and +active in us even prior to the moral law, so far as to limit it to the +condition of agreement with this law, and then it is called rational +self-love. But self-conceit reason strikes down altogether, since +all claims to self-esteem which precede agreement with the moral law +are vain and unjustifiable, for the certainty of a state of mind +that coincides with this law is the first condition of personal +worth (as we shall presently show more clearly), and prior to this +conformity any pretension to worth is false and unlawful. Now the +propensity to self-esteem is one of the inclinations which the moral +law checks, inasmuch as that esteem rests only on morality. +Therefore the moral law breaks down self-conceit. But as this law is +something positive in itself, namely, the form of an intellectual +causality, that is, of freedom, it must be an object of respect; +for, by opposing the subjective antagonism of the inclinations, it +weakens self-conceit; and since it even breaks down, that is, +humiliates, this conceit, it is an object of the highest respect +and, consequently, is the foundation of a positive feeling which is +not of empirical origin, but is known a priori. Therefore respect +for the moral law is a feeling which is produced by an intellectual +cause, and this feeling is the only one that we know quite a priori +and the necessity of which we can perceive. + +In the preceding chapter we have seen that everything that +presents itself as an object of the will prior to the moral law is +by that law itself, which is the supreme condition of practical +reason, excluded from the determining principles of the will which +we have called the unconditionally good; and that the mere practical +form which consists in the adaptation of the maxims to universal +legislation first determines what is good in itself and absolutely, +and is the basis of the maxims of a pure will, which alone is good +in every respect. However, we find that our nature as sensible +beings is such that the matter of desire (objects of inclination, +whether of hope or fear) first presents itself to us; and our +pathologically affected self, although it is in its maxims quite unfit +for universal legislation; yet, just as if it constituted our entire +self, strives to put its pretensions forward first, and to have them +acknowledged as the first and original. This propensity to make +ourselves in the subjective determining principles of our choice serve +as the objective determining principle of the will generally may be +called self-love; and if this pretends to be legislative as an +unconditional practical principle it may be called self-conceit. Now +the moral law, which alone is truly objective (namely, in every +respect), entirely excludes the influence of self-love on the +supreme practical principle, and indefinitely checks the +self-conceit that prescribes the subjective conditions of the former +as laws. Now whatever checks our self-conceit in our own judgement +humiliates; therefore the moral law inevitably humbles every man +when he compares with it the physical propensities of his nature. +That, the idea of which as a determining principle of our will humbles +us in our self-consciousness, awakes respect for itself, so far as +it is itself positive and a determining principle. Therefore the moral +law is even subjectively a cause of respect. Now since everything that +enters into self-love belongs to inclination, and all inclination +rests on feelings, and consequently whatever checks all the feelings +together in self-love has necessarily, by this very circumstance, an +influence on feeling; hence we comprehend how it is possible to +perceive a priori that the moral law can produce an effect on feeling, +in that it excludes the inclinations and the propensity to make them +the supreme practical condition, i.e., self-love, from all +participation in the supreme legislation. This effect is on one side +merely negative, but on the other side, relatively to the +restricting principle of pure practical reason, it is positive. No +special kind of feeling need be assumed for this under the name of a +practical or moral feeling as antecedent to the moral law and +serving as its foundation. + +The negative effect on feeling (unpleasantness) is pathological, +like every influence on feeling and like every feeling generally. +But as an effect of the consciousness of the moral law, and +consequently in relation to a supersensible cause, namely, the subject +of pure practical reason which is the supreme lawgiver, this feeling +of a rational being affected by inclinations is called humiliation +(intellectual self-depreciation); but with reference to the positive +source of this humiliation, the law, it is respect for it. There is +indeed no feeling for this law; but inasmuch as it removes the +resistance out of the way, this removal of an obstacle is, in the +judgement of reason, esteemed equivalent to a positive help to its +causality. Therefore this feeling may also be called a feeling of +respect for the moral law, and for both reasons together a moral +feeling. + +While the moral law, therefore, is a formal determining principle of +action by practical pure reason, and is moreover a material though +only objective determining principle of the objects of action as +called good and evil, it is also a subjective determining principle, +that is, a motive to this action, inasmuch as it has influence on +the morality of the subject and produces a feeling conducive to the +influence of the law on the will. There is here in the subject no +antecedent feeling tending to morality. For this is impossible, +since every feeling is sensible, and the motive of moral intention +must be free from all sensible conditions. On the contrary, while +the sensible feeling which is at the bottom of all our inclinations is +the condition of that impression which we call respect, the cause that +determines it lies in the pure practical reason; and this impression +therefore, on account of its origin, must be called, not a +pathological but a practical effect. For by the fact that the +conception of the moral law deprives self-love of its influence, and +self-conceit of its illusion, it lessens the obstacle to pure +practical reason and produces the conception of the superiority of its +objective law to the impulses of the sensibility; and thus, by +removing the counterpoise, it gives relatively greater weight to the +law in the judgement of reason (in the case of a will affected by +the aforesaid impulses). Thus the respect for the law is not a +motive to morality, but is morality itself subjectively considered +as a motive, inasmuch as pure practical reason, by rejecting all the +rival pretensions of self-love, gives authority to the law, which now +alone has influence. Now it is to be observed that as respect is an +effect on feeling, and therefore on the sensibility, of a rational +being, it presupposes this sensibility, and therefore also the +finiteness of such beings on whom the moral law imposes respect; and +that respect for the law cannot be attributed to a supreme being, or +to any being free from all sensibility, in whom, therefore, this +sensibility cannot be an obstacle to practical reason. + +This feeling (which we call the moral feeling) is therefore produced +simply by reason. It does not serve for the estimation of actions +nor for the foundation of the objective moral law itself, but merely +as a motive to make this of itself a maxim. But what name could we +more suitably apply to this singular feeling which cannot be +compared to any pathological feeling? It is of such a peculiar kind +that it seems to be at the disposal of reason only, and that pure +practical reason. + + {BOOK_1|CHAPTER_3 ^paragraph 10} + +Respect applies always to persons only- not to things. The latter +may arouse inclination, and if they are animals (e.g., horses, dogs, +etc.), even love or fear, like the sea, a volcano, a beast of prey; +but never respect. Something that comes nearer to this feeling is +admiration, and this, as an affection, astonishment, can apply to +things also, e.g., lofty mountains, the magnitude, number, and +distance of the heavenly bodies, the strength and swiftness of many +animals, etc. But all this is not respect. A man also may be an object +to me of love, fear, or admiration, even to astonishment, and yet +not be an object of respect. His jocose humour, his courage and +strength, his power from the rank he has amongst others, may inspire +me with sentiments of this kind, but still inner respect for him is +wanting. Fontenelle says, "I bow before a great man, but my mind +does not bow." I would add, before an humble plain man, in whom I +perceive uprightness of character in a higher degree than I am +conscious of in myself,- my mind bows whether I choose it or not, +and though I bear my head never so high that he may not forget my +superior rank. Why is this? Because his example exhibits to me a law +that humbles my self-conceit when I compare it with my conduct: a law, +the practicability of obedience to which I see proved by fact before +my eyes. Now, I may even be conscious of a like degree of uprightness, +and yet the respect remains. For since in man all good is defective, +the law made visible by an example still humbles my pride, my standard +being furnished by a man whose imperfections, whatever they may be, +are not known to me as my own are, and who therefore appears to me +in a more favourable light. Respect is a tribute which we cannot +refuse to merit, whether we will or not; we may indeed outwardly +withhold it, but we cannot help feeling it inwardly. + +Respect is so far from being a feeling of pleasure that we only +reluctantly give way to it as regards a man. We try to find +out something that may lighten the burden of it, some fault +to compensate us for the humiliation which such an example +causes. Even the dead are not always secure from this criticism, +especially if their example appears inimitable. Even the moral law +itself in its solemn majesty is exposed to this endeavour to save +oneself from yielding it respect. Can it be thought that it is for any +other reason that we are so ready to reduce it to the level of our +familiar inclination, or that it is for any other reason that we all +take such trouble to make it out to be the chosen precept of our own +interest well understood, but that we want to be free from the +deterrent respect which shows us our own unworthiness with such +severity? Nevertheless, on the other hand, so little is there pain +in it that if once one has laid aside self-conceit and allowed +practical influence to that respect, he can never be satisfied with +contemplating the majesty of this law, and the soul believes itself +elevated in proportion as it sees the holy law elevated above it and +its frail nature. No doubt great talents and activity proportioned +to them may also occasion respect or an analogous feeling. It is +very proper to yield it to them, and then it appears as if this +sentiment were the same thing as admiration. But if we look closer +we shall observe that it is always uncertain how much of the ability +is due to native talent, and how much to diligence in cultivating +it. Reason represents it to us as probably the fruit of cultivation, +and therefore as meritorious, and this notably reduces our +self-conceit, and either casts a reproach on us or urges us to +follow such an example in the way that is suitable to us. This +respect, then, which we show to such a person (properly speaking, to +the law that his example exhibits) is not mere admiration; and this is +confirmed also by the fact that when the common run of admirers +think they have learned from any source the badness of such a man's +character (for instance Voltaire's) they give up all respect for +him; whereas the true scholar still feels it at least with regard to +his talents, because he is himself engaged in a business and a +vocation which make imitation of such a man in some degree a law. + +Respect for the moral law is, therefore, the only and the +undoubted moral motive, and this feeling is directed to no object, +except on the ground of this law. The moral law first determines the +will objectively and directly in the judgement of reason; and freedom, +whose causality can be determined only by the law, consists just in +this, that it restricts all inclinations, and consequently +self-esteem, by the condition of obedience to its pure law. This +restriction now has an effect on feeling, and produces the +impression of displeasure which can be known a priori from the moral +law. Since it is so far only a negative effect which, arising from the +influence of pure practical reason, checks the activity of the +subject, so far as it is determined by inclinations, and hence +checks the opinion of his personal worth (which, in the absence of +agreement with the moral law, is reduced to nothing); hence, the +effect of this law on feeling is merely humiliation. We can, +therefore, perceive this a priori, but cannot know by it the force +of the pure practical law as a motive, but only the resistance to +motives of the sensibility. But since the same law is objectively, +that is, in the conception of pure reason, an immediate principle of +determination of the will, and consequently this humiliation takes +place only relatively to the purity of the law; hence, the lowering of +the pretensions of moral self-esteem, that is, humiliation on the +sensible side, is an elevation of the moral, i.e., practical, esteem +for the law itself on the intellectual side; in a word, it is +respect for the law, and therefore, as its cause is intellectual, a +positive feeling which can be known a priori. For whatever +diminishes the obstacles to an activity furthers this activity itself. +Now the recognition of the moral law is the consciousness of an +activity of practical reason from objective principles, which only +fails to reveal its effect in actions because subjective +(pathological) causes hinder it. Respect for the moral law then must +be regarded as a positive, though indirect, effect of it on feeling, +inasmuch as this respect weakens the impeding influence of +inclinations by humiliating self-esteem; and hence also as a subjective +principle of activity, that is, as a motive to obedience to the law, +and as a principle of the maxims of a life conformable to it. From the +notion of a motive arises that of an interest, which can never be +attributed to any being unless it possesses reason, and which +signifies a motive of the will in so far as it is conceived by the +reason. Since in a morally good will the law itself must be the +motive, the moral interest is a pure interest of practical reason +alone, independent of sense. On the notion of an interest is based +that of a maxim. This, therefore, is morally good only in case it +rests simply on the interest taken in obedience to the law. All +three notions, however, that of a motive, of an interest, and of a +maxim, can be applied only to finite beings. For they all suppose a +limitation of the nature of the being, in that the subjective +character of his choice does not of itself agree with the objective +law of a practical reason; they suppose that the being requires to +be impelled to action by something, because an internal obstacle +opposes itself. Therefore they cannot be applied to the Divine will. + +There is something so singular in the unbounded esteem for the +pure moral law, apart from all advantage, as it is presented for our +obedience by practical reason, the voice of which makes even the +boldest sinner tremble and compels him to hide himself from it, that +we cannot wonder if we find this influence of a mere intellectual idea +on the feelings quite incomprehensible to speculative reason and +have to be satisfied with seeing so much of this a priori that such +a feeling is inseparably connected with the conception of the moral +law in every finite rational being. If this feeling of respect were +pathological, and therefore were a feeling of pleasure based on the +inner sense, it would be in vain to try to discover a connection of it +with any idea a priori. But [it] is a feeling that applies merely to +what is practical, and depends on the conception of a law, simply as +to its form, not on account of any object, and therefore cannot be +reckoned either as pleasure or pain, and yet produces an interest in +obedience to the law, which we call the moral interest, just as the +capacity of taking such an interest in the law (or respect for the +moral law itself) is properly the moral feeling. + +The consciousness of a free submission of the will to the law, yet +combined with an inevitable constraint put upon all inclinations, +though only by our own reason, is respect for the law. The law that +demands this respect and inspires it is clearly no other than the +moral (for no other precludes all inclinations from exercising any +direct influence on the will). An action which is objectively +practical according to this law, to the exclusion of every determining +principle of inclination, is duty, and this by reason of that +exclusion includes in its concept practical obligation, that is, a +determination to actions, however reluctantly they may be done. The +feeling that arises from the consciousness of this obligation is not +pathological, as would be a feeling produced by an object of the +senses, but practical only, that is, it is made possible by a +preceding (objective) determination of the will and a causality of the +reason. As submission to the law, therefore, that is, as a command +(announcing constraint for the sensibly affected subject), it contains +in it no pleasure, but on the contrary, so far, pain in the action. On +the other hand, however, as this constraint is exercised merely by the +legislation of our own reason, it also contains something elevating, +and this subjective effect on feeling, inasmuch as pure practical +reason is the sole cause of it, may be called in this respect +self-approbation, since we recognize ourselves as determined thereto +solely by the law without any interest, and are now conscious of a +quite different interest subjectively produced thereby, and which is +purely practical and free; and our taking this interest in an action +of duty is not suggested by any inclination, but is commanded and +actually brought about by reason through the practical law; whence +this feeling obtains a special name, that of respect. + + {BOOK_1|CHAPTER_3 ^paragraph 15} + +The notion of duty, therefore, requires in the action, +objectively, agreement with the law, and, subjectively in its maxim, +that respect for the law shall be the sole mode in which the will is +determined thereby. And on this rests the distinction between the +consciousness of having acted according to duty and from duty, that +is, from respect for the law. The former (legality) is possible even +if inclinations have been the determining principles of the will; +but the latter (morality), moral worth, can be placed only in this, +that the action is done from duty, that is, simply for the sake of the +law. * + + + +* If we examine accurately the notion of respect for persons as it +has been already laid down, we shall perceive that it always rests +on the consciousness of a duty which an example shows us, and that +respect, therefore, can never have any but a moral ground, and that it +is very good and even, in a psychological point of view, very useful +for the knowledge of mankind, that whenever we use this expression +we should attend to this secret and marvellous, yet often recurring, +regard which men in their judgement pay to the moral law. + + + +It is of the greatest importance to attend with the utmost exactness +in all moral judgements to the subjective principle of all maxims, +that all the morality of actions may be placed in the necessity of +acting from duty and from respect for the law, not from love and +inclination for that which the actions are to produce. For men and all +created rational beings moral necessity is constraint, that is +obligation, and every action based on it is to be conceived as a duty, +not as a proceeding previously pleasing, or likely to be pleasing to +us of our own accord. As if indeed we could ever bring it about that +without respect for the law, which implies fear, or at least +apprehension of transgression, we of ourselves, like the independent +Deity, could ever come into possession of holiness of will by the +coincidence of our will with the pure moral law becoming as it were +part of our nature, never to be shaken (in which case the law would +cease to be a command for us, as we could never be tempted to be +untrue to it). + + {BOOK_1|CHAPTER_3 ^paragraph 20} + +The moral law is in fact for the will of a perfect being a law of +holiness, but for the will of every finite rational being a law of +duty, of moral constraint, and of the determination of its actions +by respect for this law and reverence for its duty. No other +subjective principle must be assumed as a motive, else while the +action might chance to be such as the law prescribes, yet, as does not +proceed from duty, the intention, which is the thing properly in +question in this legislation, is not moral. + +It is a very beautiful thing to do good to men from love to them and +from sympathetic good will, or to be just from love of order; but this +is not yet the true moral maxim of our conduct which is suitable to +our position amongst rational beings as men, when we pretend with +fanciful pride to set ourselves above the thought of duty, like +volunteers, and, as if we were independent on the command, to want +to do of our own good pleasure what we think we need no command to do. +We stand under a discipline of reason and in all our maxims must not +forget our subjection to it, nor withdraw anything therefrom, or by an +egotistic presumption diminish aught of the authority of the law +(although our own reason gives it) so as to set the determining +principle of our will, even though the law be conformed to, anywhere +else but in the law itself and in respect for this law. Duty and +obligation are the only names that we must give to our relation to the +moral law. We are indeed legislative members of a moral kingdom +rendered possible by freedom, and presented to us by reason as an +object of respect; but yet we are subjects in it, not the sovereign, +and to mistake our inferior position as creatures, and +presumptuously to reject the authority of the moral law, is already to +revolt from it in spirit, even though the letter of it is fulfilled. + +With this agrees very well the possibility of such a command as: +Love God above everything, and thy neighbour as thyself. * For as a +command it requires respect for a law which commands love and does not +leave it to our own arbitrary choice to make this our principle. +Love to God, however, considered as an inclination (pathological +love), is impossible, for He is not an object of the senses. The +same affection towards men is possible no doubt, but cannot be +commanded, for it is not in the power of any man to love anyone at +command; therefore it is only practical love that is meant in that +pith of all laws. To love God means, in this sense, to like to do +His commandments; to love one's neighbour means to like to practise +all duties towards him. But the command that makes this a rule +cannot command us to have this disposition in actions conformed to +duty, but only to endeavour after it. For a command to like to do a +thing is in itself contradictory, because if we already know of +ourselves what we are bound to do, and if further we are conscious +of liking to do it, a command would be quite needless; and if we do it +not willingly, but only out of respect for the law, a command that +makes this respect the motive of our maxim would directly counteract +the disposition commanded. That law of all laws, therefore, like all +the moral precepts of the Gospel, exhibits the moral disposition in +all its perfection, in which, viewed as an ideal of holiness, it is +not attainable by any creature, but yet is the pattern which we should +strive to approach, and in an uninterrupted but infinite progress +become like to. In fact, if a rational creature could ever reach +this point, that he thoroughly likes to do all moral laws, this +would mean that there does not exist in him even the possibility of +a desire that would tempt him to deviate from them; for to overcome +such a desire always costs the subject some sacrifice and therefore +requires self-compulsion, that is, inward constraint to something that +one does not quite like to do; and no creature can ever reach this +stage of moral disposition. For, being a creature, and therefore +always dependent with respect to what he requires for complete +satisfaction, he can never be quite free from desires and +inclinations, and as these rest on physical causes, they can never +of themselves coincide with the moral law, the sources of which are +quite different; and therefore they make it necessary to found the +mental disposition of one's maxims on moral obligation, not on ready +inclination, but on respect, which demands obedience to the law, +even though one may not like it; not on love, which apprehends no +inward reluctance of the will towards the law. Nevertheless, this +latter, namely, love to the law (which would then cease to be a +command, and then morality, which would have passed subjectively +into holiness, would cease to be virtue) must be the constant though +unattainable goal of his endeavours. For in the case of what we highly +esteem, but yet (on account of the consciousness of our weakness) +dread, the increased facility of satisfying it changes the most +reverential awe into inclination, and respect into love; at least this +would be the perfection of a disposition devoted to the law, if it +were possible for a creature to attain it. + + + +* This law is in striking contrast with the principle of private +happiness which some make the supreme principle of morality. This +would be expressed thus: Love thyself above everything, and God and +thy neighbour for thine own sake. + + {BOOK_1|CHAPTER_3 ^paragraph 25} + + + +This reflection is intended not so much to clear up the +evangelical command just cited, in order to prevent religious +fanaticism in regard to love of God, but to define accurately the +moral disposition with regard directly to our duties towards men, +and to check, or if possible prevent, a merely moral fanaticism +which infects many persons. The stage of morality on which man (and, +as far as we can see, every rational creature) stands is respect for +the moral law. The disposition that he ought to have in obeying this +is to obey it from duty, not from spontaneous inclination, or from +an endeavour taken up from liking and unbidden; and this proper +moral condition in which he can always be is virtue, that is, moral +disposition militant, and not holiness in the fancied possession of +a perfect purity of the disposition of the will. It is nothing but +moral fanaticism and exaggerated self-conceit that is infused into the +mind by exhortation to actions as noble, sublime, and magnanimous, +by which men are led into the delusion that it is not duty, that is, +respect for the law, whose yoke (an easy yoke indeed, because reason +itself imposes it on us) they must bear, whether they like it or +not, that constitutes the determining principle of their actions, +and which always humbles them while they obey it; fancying that +those actions are expected from them, not from duty, but as pure +merit. For not only would they, in imitating such deeds from such a +principle, not have fulfilled the spirit of the law in the least, +which consists not in the legality of the action (without regard to +principle), but in the subjection of the mind to the law; not only +do they make the motives pathological (seated in sympathy or +self-love), not moral (in the law), but they produce in this way a +vain, high-flying, fantastic way of thinking, flattering themselves +with a spontaneous goodness of heart that needs neither spur nor +bridle, for which no command is needed, and thereby forgetting their +obligation, which they ought to think of rather than merit. Indeed +actions of others which are done with great sacrifice, and merely +for the sake of duty, may be praised as noble and sublime, but only so +far as there are traces which suggest that they were done wholly out +of respect for duty and not from excited feelings. If these, +however, are set before anyone as examples to be imitated, respect for +duty (which is the only true moral feeling) must be employed as the +motive- this severe holy precept which never allows our vain self-love +to dally with pathological impulses (however analogous they may be +to morality), and to take a pride in meritorious worth. Now if we +search we shall find for all actions that are worthy of praise a law +of duty which commands, and does not leave us to choose what may be +agreeable to our inclinations. This is the only way of representing +things that can give a moral training to the soul, because it alone is +capable of solid and accurately defined principles. + +If fanaticism in its most general sense is a deliberate over +stepping of the limits of human reason, then moral fanaticism is +such an over stepping of the bounds that practical pure reason sets to +mankind, in that it forbids us to place the subjective determining +principle of correct actions, that is, their moral motive, in anything +but the law itself, or to place the disposition which is thereby +brought into the maxims in anything but respect for this law, and +hence commands us to take as the supreme vital principle of all +morality in men the thought of duty, which strikes down all +arrogance as well as vain self-love. + +If this is so, it is not only writers of romance or sentimental +educators (although they may be zealous opponents of +sentimentalism), but sometimes even philosophers, nay, even the +severest of all, the Stoics, that have brought in moral fanaticism +instead of a sober but wise moral discipline, although the +fanaticism of the latter was more heroic, that of the former of an +insipid, effeminate character; and we may, without hypocrisy, say of +the moral teaching of the Gospel, that it first, by the purity of +its moral principle, and at the same time by its suitability to the +limitations of finite beings, brought all the good conduct of men +under the discipline of a duty plainly set before their eyes, which +does not permit them to indulge in dreams of imaginary moral +perfections; and that it also set the bounds of humility (that is, +self-knowledge) to self-conceit as well as to self-love, both which +are ready to mistake their limits. + +Duty! Thou sublime and mighty name that dost embrace nothing +charming or insinuating, but requirest submission, and yet seekest not +to move the will by threatening aught that would arouse natural +aversion or terror, but merely holdest forth a law which of itself +finds entrance into the mind, and yet gains reluctant reverence +(though not always obedience), a law before which all inclinations are +dumb, even though they secretly counter-work it; what origin is +there worthy of thee, and where is to be found the root of thy noble +descent which proudly rejects all kindred with the inclinations; a +root to be derived from which is the indispensable condition of the +only worth which men can give themselves? + + {BOOK_1|CHAPTER_3 ^paragraph 30} + +It can be nothing less than a power which elevates man above himself +(as a part of the world of sense), a power which connects him with +an order of things that only the understanding can conceive, with a +world which at the same time commands the whole sensible world, and +with it the empirically determinable existence of man in time, as well +as the sum total of all ends (which totality alone suits such +unconditional practical laws as the moral). This power is nothing +but personality, that is, freedom and independence on the mechanism of +nature, yet, regarded also as a faculty of a being which is subject to +special laws, namely, pure practical laws given by its own reason; +so that the person as belonging to the sensible world is subject to +his own personality as belonging to the intelligible [supersensible] +world. It is then not to be wondered at that man, as belonging to both +worlds, must regard his own nature in reference to its second and +highest characteristic only with reverence, and its laws with the +highest respect. + +On this origin are founded many expressions which designate the +worth of objects according to moral ideas. The moral law is holy +(inviolable). Man is indeed unholy enough, but he must regard humanity +in his own person as holy. In all creation every thing one chooses and +over which one has any power, may be used merely as means; man +alone, and with him every rational creature, is an end in himself. +By virtue of the autonomy of his freedom he is the subject of the +moral law, which is holy. Just for this reason every will, even +every person's own individual will, in relation to itself, is +restricted to the condition of agreement with the autonomy of the +rational being, that is to say, that it is not to be subject to any +purpose which cannot accord with a law which might arise from the will +of the passive subject himself; the latter is, therefore, never to +be employed merely as means, but as itself also, concurrently, an end. +We justly attribute this condition even to the Divine will, with +regard to the rational beings in the world, which are His creatures, +since it rests on their personality, by which alone they are ends in +themselves. + +This respect-inspiring idea of personality which sets before our +eyes the sublimity of our nature (in its higher aspect), while at +the same time it shows us the want of accord of our conduct with it +and thereby strikes down self-conceit, is even natural to the +commonest reason and easily observed. Has not every even moderately +honourable man sometimes found that, where by an otherwise inoffensive +lie he might either have withdrawn himself from an unpleasant +business, or even have procured some advantages for a loved and +well-deserving friend, he has avoided it solely lest he should despise +himself secretly in his own eyes? When an upright man is in the +greatest distress, which he might have avoided if he could only have +disregarded duty, is he not sustained by the consciousness that he has +maintained humanity in its proper dignity in his own person and +honoured it, that he has no reason to be ashamed of himself in his own +sight, or to dread the inward glance of self-examination? This +consolation is not happiness, it is not even the smallest part of +it, for no one would wish to have occasion for it, or would, +perhaps, even desire a life in such circumstances. But he lives, and +he cannot endure that he should be in his own eyes unworthy of life. +This inward peace is therefore merely negative as regards what can +make life pleasant; it is, in fact, only the escaping the danger of +sinking in personal worth, after everything else that is valuable +has been lost. It is the effect of a respect for something quite +different from life, something in comparison and contrast with which +life with all its enjoyment has no value. He still lives only +because it is his duty, not because he finds anything pleasant in +life. + +Such is the nature of the true motive of pure practical reason; it +is no other than the pure moral law itself, inasmuch as it makes us +conscious of the sublimity of our own supersensible existence and +subjectively produces respect for their higher nature in men who are +also conscious of their sensible existence and of the consequent +dependence of their pathologically very susceptible nature. Now with +this motive may be combined so many charms and satisfactions of life +that even on this account alone the most prudent choice of a +rational Epicurean reflecting on the greatest advantage of life +would declare itself on the side of moral conduct, and it may even +be advisable to join this prospect of a cheerful enjoyment of life +with that supreme motive which is already sufficient of itself; but +only as a counterpoise to the attractions which vice does not fail +to exhibit on the opposite side, and not so as, even in the smallest +degree, to place in this the proper moving power when duty is in +question. For that would be just the same as to wish to taint the +purity of the moral disposition in its source. The majesty of duty has +nothing to do with enjoyment of life; it has its special law and its +special tribunal, and though the two should be never so well shaken +together to be given well mixed, like medicine, to the sick soul, +yet they will soon separate of themselves; and if they do not, the +former will not act; and although physical life might gain somewhat in +force, the moral life would fade away irrecoverably. + + + + {BOOK_1|CHAPTER_3 ^paragraph 35} + +Critical Examination of the Analytic of Pure Practical Reason. + + + +By the critical examination of a science, or of a portion of it, +which constitutes a system by itself, I understand the inquiry and +proof why it must have this and no other systematic form, when we +compare it with another system which is based on a similar faculty +of knowledge. Now practical and speculative reason are based on the +same faculty, so far as both are pure reason. Therefore the difference +in their systematic form must be determined by the comparison of both, +and the ground of this must be assigned. + +The Analytic of pure theoretic reason had to do with the knowledge +of such objects as may have been given to the understanding, and was +obliged therefore to begin from intuition and consequently (as this is +always sensible) from sensibility; and only after that could advance +to concepts (of the objects of this intuition), and could only end +with principles after both these had preceded. On the contrary, +since practical reason has not to do with objects so as to know +them, but with its own faculty of realizing them (in accordance with +the knowledge of them), that is, with a will which is a causality, +inasmuch as reason contains its determining principle; since, +consequently, it has not to furnish an object of intuition, but as +practical reason has to furnish only a law (because the notion of +causality always implies the reference to a law which determines the +existence of the many in relation to one another); hence a critical +examination of the Analytic of reason, if this is to be practical +reason (and this is properly the problem), must begin with the +possibility of practical principles a priori. Only after that can it +proceed to concepts of the objects of a practical reason, namely, +those of absolute good and evil, in order to assign them in accordance +with those principles (for prior to those principles they cannot +possibly be given as good and evil by any faculty of knowledge), and +only then could the section be concluded with the last chapter, +that, namely, which treats of the relation of the pure practical +reason to the sensibility and of its necessary influence thereon, +which is a priori cognisable, that is, of the moral sentiment. Thus +the Analytic of the practical pure reason has the whole extent of +the conditions of its use in common with the theoretical, but in +reverse order. The Analytic of pure theoretic reason was divided +into transcendental Aesthetic and transcendental Logic, that of the +practical reversely into Logic and Aesthetic of pure practical +reason (if I may, for the sake of analogy merely, use these +designations, which are not quite suitable). This logic again was +there divided into the Analytic of concepts and that of principles: +here into that of principles and concepts. The Aesthetic also had in +the former case two parts, on account of the two kinds of sensible +intuition; here the sensibility is not considered as a capacity of +intuition at all, but merely as feeling (which can be a subjective +ground of desire), and in regard to it pure practical reason admits no +further division. + +It is also easy to see the reason why this division into two parts +with its subdivision was not actually adopted here (as one might +have been induced to attempt by the example of the former critique). +For since it is pure reason that is here considered in its practical +use, and consequently as proceeding from a priori principles, and +not from empirical principles of determination, hence the division +of the analytic of pure practical reason must resemble that of a +syllogism; namely, proceeding from the universal in the major +premiss (the moral principle), through a minor premiss containing a +subsumption of possible actions (as good or evil) under the former, to +the conclusion, namely, the subjective determination of the will (an +interest in the possible practical good, and in the maxim founded on +it). He who has been able to convince himself of the truth of the +positions occurring in the Analytic will take pleasure in such +comparisons; for they justly suggest the expectation that we may +perhaps some day be able to discern the unity of the whole faculty +of reason (theoretical as well as practical) and be able to derive all +from one principle, which, is what human reason inevitably demands, as +it finds complete satisfaction only in a perfectly systematic unity of +its knowledge. + + {BOOK_1|CHAPTER_3 ^paragraph 40} + +If now we consider also the contents of the knowledge that we can +have of a pure practical reason, and by means of it, as shown by the +Analytic, we find, along with a remarkable analogy between it and +the theoretical, no less remarkable differences. As regards the +theoretical, the faculty of a pure rational cognition a priori could +be easily and evidently proved by examples from sciences (in which, as +they put their principles to the test in so many ways by methodical +use, there is not so much reason as in common knowledge to fear a +secret mixture of empirical principles of cognition). But, that pure +reason without the admixture of any empirical principle is practical +of itself, this could only be shown from the commonest practical use +of reason, by verifying the fact, that every man's natural reason +acknowledges the supreme practical principle as the supreme law of his +will- a law completely a priori and not depending on any sensible +data. It was necessary first to establish and verify the purity of its +origin, even in the judgement of this common reason, before science +could take it in hand to make use of it, as a fact, that is, prior +to all disputation about its possibility, and all the consequences +that may be drawn from it. But this circumstance may be readily +explained from what has just been said; because practical pure +reason must necessarily begin with principles, which therefore must be +the first data, the foundation of all science, and cannot be derived +from it. It was possible to effect this verification of moral +principles as principles of a pure reason quite well, and with +sufficient certainty, by a single appeal to the judgement of common +sense, for this reason, that anything empirical which might slip +into our maxims as a determining principle of the will can be detected +at once by the feeling of pleasure or pain which necessarily +attaches to it as exciting desire; whereas pure practical reason +positively refuses to admit this feeling into its principle as a +condition. The heterogeneity of the determining principles (the +empirical and rational) is clearly detected by this resistance of a +practically legislating reason against every admixture of inclination, +and by a peculiar kind of sentiment, which, however, does not +precede the legislation of the practical reason, but, on the contrary, +is produced by this as a constraint, namely, by the feeling of a +respect such as no man has for inclinations of whatever kind but for +the law only; and it is detected in so marked and prominent a manner +that even the most uninstructed cannot fail to see at once in an +example presented to him, that empirical principles of volition may +indeed urge him to follow their attractions, but that he can never +be expected to obey anything but the pure practical law of reason +alone. + +The distinction between the doctrine of happiness and the doctrine +of morality, in the former of which empirical principles constitute +the entire foundation, while in the second they do not form the +smallest part of it, is the first and most important office of the +Analytic of pure practical reason; and it must proceed in it with as +much exactness and, so to speak, scrupulousness, as any geometer in +his work. The philosopher, however, has greater difficulties to +contend with here (as always in rational cognition by means of +concepts merely without construction), because he cannot take any +intuition as a foundation (for a pure noumenon). He has, however, this +advantage that, like the chemist, he can at any time make an +experiment with every man's practical reason for the purpose of +distinguishing the moral (pure) principle of determination from the +empirical; namely, by adding the moral law (as a determining +principle) to the empirically affected will (e.g., that of the man who +would be ready to lie because he can gain something thereby). It is as +if the analyst added alkali to a solution of lime in hydrochloric +acid, the acid at once forsakes the lime, combines with the alkali, +and the lime is precipitated. Just in the same way, if to a man who is +otherwise honest (or who for this occasion places himself only in +thought in the position of an honest man), we present the moral law by +which he recognises the worthlessness of the liar, his practical +reason (in forming a judgement of what ought to be done) at once +forsakes the advantage, combines with that which maintains in him +respect for his own person (truthfulness), and the advantage after +it has been separated and washed from every particle of reason +(which is altogether on the side of duty) is easily weighed by +everyone, so that it can enter into combination with reason in other +cases, only not where it could be opposed to the moral law, which +reason never forsakes, but most closely unites itself with. + +But it does not follow that this distinction between the principle +of happiness and that of morality is an opposition between them, and +pure practical reason does not require that we should renounce all +claim to happiness, but only that the moment duty is in question we +should take no account of happiness. It may even in certain respects +be a duty to provide for happiness; partly, because (including +skill, wealth, riches) it contains means for the fulfilment of our +duty; partly, because the absence of it (e.g., poverty) implies +temptations to transgress our duty. But it can never be an immediate +duty to promote our happiness, still less can it be the principle of +all duty. Now, as all determining principles of the will, except the +law of pure practical reason alone (the moral law), are all +empirical and, therefore, as such, belong to the principle of +happiness, they must all be kept apart from the supreme principle of +morality and never be incorporated with it as a condition; since +this would be to destroy all moral worth just as much as any empirical +admixture with geometrical principles would destroy the certainty of +mathematical evidence, which in Plato's opinion is the most +excellent thing in mathematics, even surpassing their utility. + +Instead, however, of the deduction of the supreme principle of +pure practical reason, that is, the explanation of the possibility +of such a knowledge a priori, the utmost we were able to do was to +show that if we saw the possibility of the freedom of an efficient +cause, we should also see not merely the possibility, but even the +necessity, of the moral law as the supreme practical law of rational +beings, to whom we attribute freedom of causality of their will; +because both concepts are so inseparably united that we might define +practical freedom as independence of the will on anything but the +moral law. But we cannot perceive the possibility of the freedom of an +efficient cause, especially in the world of sense; we are fortunate if +only we can be sufficiently assured that there is no proof of its +impossibility, and are now, by the moral law which postulates it, +compelled and therefore authorized to assume it. However, there are +still many who think that they can explain this freedom on empirical +principles, like any other physical faculty, and treat it as a +psychological property, the explanation of which only requires a +more exact study of the nature of the soul and of the motives of the +will, and not as a transcendental predicate of the causality of a +being that belongs to the world of sense (which is really the +point). They thus deprive us of the grand revelation which we obtain +through practical reason by means of the moral law, the revelation, +namely, of a supersensible world by the realization of the otherwise +transcendent concept of freedom, and by this deprive us also of the +moral law itself, which admits no empirical principle of +determination. Therefore it will be necessary to add something here as +a protection against this delusion and to exhibit empiricism in its +naked superficiality. + +The notion of causality as physical necessity, in opposition to +the same notion as freedom, concerns only the existence of things so +far as it is determinable in time, and, consequently, as phenomena, in +opposition to their causality as things in themselves. Now if we +take the attributes of existence of things in time for attributes of +things in themselves (which is the common view), then it is impossible +to reconcile the necessity of the causal relation with freedom; they +are contradictory. For from the former it follows that every event, +and consequently every action that takes place at a certain point of +time, is a necessary result of what existed in time preceding. Now +as time past is no longer in my power, hence every action that I +perform must be the necessary result of certain determining grounds +which are not in my power, that is, at the moment in which I am acting +I am never free. Nay, even if I assume that my whole existence is +independent on any foreign cause (for instance, God), so that the +determining principles of my causality, and even of my whole +existence, were not outside myself, yet this would not in the least +transform that physical necessity into freedom. For at every moment of +time I am still under the necessity of being determined to action by +that which is not in my power, and the series of events infinite a +parte priori, which I only continue according to a pre-determined +order and could never begin of myself, would be a continuous +physical chain, and therefore my causality would never be freedom. + + {BOOK_1|CHAPTER_3 ^paragraph 45} + +If, then, we would attribute freedom to a being whose existence is +determined in time, we cannot except him from the law of necessity +as to all events in his existence and, consequently, as to his actions +also; for that would be to hand him over to blind chance. Now as +this law inevitably applies to all the causality of things, so far +as their existence is determinable in time, it follows that if this +were the mode in which we had also to conceive the existence of +these things in themselves, freedom must be rejected as a vain and +impossible conception. Consequently, if we would still save it, no +other way remains but to consider that the existence of a thing, so +far as it is determinable in time, and therefore its causality, +according to the law of physical necessity, belong to appearance, +and to attribute freedom to the same being as a thing in itself. +This is certainly inevitable, if we would retain both these +contradictory concepts together; but in application, when we try to +explain their combination in one and the same action, great +difficulties present themselves which seem to render such a +combination impracticable. + +When I say of a man who commits a theft that, by the law of +causality, this deed is a necessary result of the determining causes +in preceding time, then it was impossible that it could not have +happened; how then can the judgement, according to the moral law, make +any change, and suppose that it could have been omitted, because the +law says that it ought to have been omitted; that is, how can a man be +called quite free at the same moment, and with respect to the same +action in which he is subject to an inevitable physical necessity? +Some try to evade this by saying that the causes that determine his +causality are of such a kind as to agree with a comparative notion +of freedom. According to this, that is sometimes called a free effect, +the determining physical cause of which lies within the acting thing +itself, e.g., that which a projectile performs when it is in free +motion, in which case we use the word freedom, because while it is +in flight it is not urged by anything external; or as we call the +motion of a clock a free motion, because it moves its hands itself, +which therefore do not require to be pushed by external force; so +although the actions of man are necessarily determined by causes which +precede in time, we yet call them free, because these causes are ideas +produced by our own faculties, whereby desires are evoked on +occasion of circumstances, and hence actions are wrought according +to our own pleasure. This is a wretched subterfuge with which some +persons still let themselves be put off, and so think they have +solved, with a petty word- jugglery, that difficult problem, at the +solution of which centuries have laboured in vain, and which can +therefore scarcely be found so completely on the surface. In fact, +in the question about the freedom which must be the foundation of +all moral laws and the consequent responsibility, it does not matter +whether the principles which necessarily determine causality by a +physical law reside within the subject or without him, or in the +former case whether these principles are instinctive or are +conceived by reason, if, as is admitted by these men themselves, these +determining ideas have the ground of their existence in time and in +the antecedent state, and this again in an antecedent, etc. Then it +matters not that these are internal; it matters not that they have a +psychological and not a mechanical causality, that is, produce actions +by means of ideas and not by bodily movements; they are still +determining principles of the causality of a being whose existence +is determinable in time, and therefore under the necessitation of +conditions of past time, which therefore, when the subject has to act, +are no longer in his power. This may imply psychological freedom (if +we choose to apply this term to a merely internal chain of ideas in +the mind), but it involves physical necessity and, therefore, leaves +no room for transcendental freedom, which must be conceived as +independence on everything empirical, and, consequently, on nature +generally, whether it is an object of the internal sense considered in +time only, or of the external in time and space. Without this +freedom (in the latter and true sense), which alone is practical a +priori, no moral law and no moral imputation are possible. Just for +this reason the necessity of events in time, according to the physical +law of causality, may be called the mechanism of nature, although we +do not mean by this that things which are subject to it must be really +material machines. We look here only to the necessity of the +connection of events in a time-series as it is developed according +to the physical law, whether the subject in which this development +takes place is called automaton materiale when the mechanical being is +moved by matter, or with Leibnitz spirituale when it is impelled by +ideas; and if the freedom of our will were no other than the latter +(say the psychological and comparative, not also transcendental, +that is, absolute), then it would at bottom be nothing better than the +freedom of a turnspit, which, when once it is wound up, accomplishes +its motions of itself. + +Now, in order to remove in the supposed case the apparent +contradiction between freedom and the mechanism of nature in one and +the same action, we must remember what was said in the Critique of +Pure Reason, or what follows therefrom; viz., that the necessity of +nature, which cannot co-exist with the freedom of the subject, +appertains only to the attributes of the thing that is subject to +time-conditions, consequently only to those of the acting subject as a +phenomenon; that therefore in this respect the determining +principles of every action of the same reside in what belongs to +past time and is no longer in his power (in which must be included his +own past actions and the character that these may determine for him in +his own eyes as a phenomenon). But the very same subject, being on the +other side conscious of himself as a thing in himself, considers his +existence also in so far as it is not subject to time-conditions, +and regards himself as only determinable by laws which he gives +himself through reason; and in this his existence nothing is +antecedent to the determination of his will, but every action, and +in general every modification of his existence, varying according to +his internal sense, even the whole series of his existence as a +sensible being is in the consciousness of his supersensible +existence nothing but the result, and never to be regarded as the +determining principle, of his causality as a noumenon. In this view +now the rational being can justly say of every unlawful action that he +performs, that he could very well have left it undone; although as +appearance it is sufficiently determined in the past, and in this +respect is absolutely necessary; for it, with all the past which +determines it, belongs to the one single phenomenon of his character +which he makes for himself, in consequence of which he imputes the +causality of those appearances to himself as a cause independent on +sensibility. + +With this agree perfectly the judicial sentences of that wonderful +faculty in us which we call conscience. A man may use as much art as +he likes in order to paint to himself an unlawful act, that he +remembers, as an unintentional error, a mere oversight, such as one +can never altogether avoid, and therefore as something in which he was +carried away by the stream of physical necessity, and thus to make +himself out innocent, yet he finds that the advocate who speaks in his +favour can by no means silence the accuser within, if only he is +conscious that at the time when he did this wrong he was in his +senses, that is, in possession of his freedom; and, nevertheless, he +accounts for his error from some bad habits, which by gradual +neglect of attention he has allowed to grow upon him to such a +degree that he can regard his error as its natural consequence, +although this cannot protect him from the blame and reproach which +he casts upon himself. This is also the ground of repentance for a +long past action at every recollection of it; a painful feeling +produced by the moral sentiment, and which is practically void in so +far as it cannot serve to undo what has been done. (Hence Priestley, +as a true and consistent fatalist, declares it absurd, and he deserves +to be commended for this candour more than those who, while they +maintain the mechanism of the will in fact, and its freedom in words +only, yet wish it to be thought that they include it in their system +of compromise, although they do not explain the possibility of such +moral imputation.) But the pain is quite legitimate, because when +the law of our intelligible [supersensible] existence (the moral +law) is in question, reason recognizes no distinction of time, and +only asks whether the event belongs to me, as my act, and then +always morally connects the same feeling with it, whether it has +happened just now or long ago. For in reference to the supersensible +consciousness of its existence (i.e., freedom) the life of sense is +but a single phenomenon, which, inasmuch as it contains merely +manifestations of the mental disposition with regard to the moral +law (i.e., of the character), must be judged not according to the +physical necessity that belongs to it as phenomenon, but according +to the absolute spontaneity of freedom. It may therefore be admitted +that, if it were possible to have so profound an insight into a +man's mental character as shown by internal as well as external +actions as to know all its motives, even the smallest, and likewise +all the external occasions that can influence them, we could calculate +a man's conduct for the future with as great certainty as a lunar or +solar eclipse; and nevertheless we may maintain that the man is +free. In fact, if we were capable of a further glance, namely, an +intellectual intuition of the same subject (which indeed is not +granted to us, and instead of it we have only the rational concept), +then we should perceive that this whole chain of appearances in regard +to all that concerns the moral laws depends on the spontaneity of +the subject as a thing in itself, of the determination of which no +physical explanation can be given. In default of this intuition, the +moral law assures us of this distinction between the relation of our +actions as appearance to our sensible nature, and the relation of this +sensible nature to the supersensible substratum in us. In this view, +which is natural to our reason, though inexplicable, we can also +justify some judgements which we passed with all conscientiousness, +and which yet at first sight seem quite opposed to all equity. There +are cases in which men, even with the same education which has been +profitable to others, yet show such early depravity, and so continue +to progress in it to years of manhood, that they are thought to be +born villains, and their character altogether incapable of +improvement; and nevertheless they are judged for what they do or +leave undone, they are reproached for their faults as guilty; nay, +they themselves (the children) regard these reproaches as well +founded, exactly as if in spite of the hopeless natural quality of +mind ascribed to them, they remained just as responsible as any +other man. This could not happen if we did not suppose that whatever +springs from a man's choice (as every action intentionally performed +undoubtedly does) has as its foundation a free causality, which from +early youth expresses its character in its manifestations (i.e., +actions). These, on account of the uniformity of conduct, exhibit a +natural connection, which however does not make the vicious quality of +the will necessary, but on the contrary, is the consequence of the +evil principles voluntarily adopted and unchangeable, which only +make it so much the more culpable and deserving of punishment. There +still remains a difficulty in the combination of freedom with the +mechanism of nature in a being belonging to the world of sense; a +difficulty which, even after all the foregoing is admitted, +threatens freedom with complete destruction. But with this danger +there is also a circumstance that offers hope of an issue still +favourable to freedom; namely, that the same difficulty presses much +more strongly (in fact as we shall presently see, presses only) on the +system that holds the existence determinable in time and space to be +the existence of things in themselves; it does not therefore oblige us +to give up our capital supposition of the ideality of time as a mere +form of sensible intuition, and consequently as a mere manner of +representation which is proper to the subject as belonging to the +world of sense; and therefore it only requires that this view be +reconciled with this idea. + +The difficulty is as follows: Even if it is admitted that the +supersensible subject can be free with respect to a given action, +although, as a subject also belonging to the world of sense, he is +under mechanical conditions with respect to the same action, still, as +soon as we allow that God as universal first cause is also the cause +of the existence of substance (a proposition which can never be +given up without at the same time giving up the notion of God as the +Being of all beings, and therewith giving up his all sufficiency, on +which everything in theology depends), it seems as if we must admit +that a man's actions have their determining principle in something +which is wholly out of his power- namely, in the causality of a +Supreme Being distinct from himself and on whom his own existence +and the whole determination of his causality are absolutely dependent. +In point of fact, if a man's actions as belonging to his modifications +in time were not merely modifications of him as appearance, but as a +thing in itself, freedom could not be saved. Man would be a marionette +or an automaton, like Vaucanson's, prepared and wound up by the +Supreme Artist. Self-consciousness would indeed make him a thinking +automaton; but the consciousness of his own spontaneity would be +mere delusion if this were mistaken for freedom, and it would +deserve this name only in a comparative sense, since, although the +proximate determining causes of its motion and a long series of +their determining causes are internal, yet the last and highest is +found in a foreign hand. Therefore I do not see how those who still +insist on regarding time and space as attributes belonging to the +existence of things in themselves, can avoid admitting the fatality of +actions; or if (like the otherwise acute Mendelssohn) they allow +them to be conditions necessarily belonging to the existence of finite +and derived beings, but not to that of the infinite Supreme Being, I +do not see on what ground they can justify such a distinction, or, +indeed, how they can avoid the contradiction that meets them, when +they hold that existence in time is an attribute necessarily belonging +to finite things in themselves, whereas God is the cause of this +existence, but cannot be the cause of time (or space) itself (since +this must be presupposed as a necessary a priori condition of the +existence of things); and consequently as regards the existence of +these things. His causality must be subject to conditions and even +to the condition of time; and this would inevitably bring in +everything contradictory to the notions of His infinity and +independence. On the other hand, it is quite easy for us to draw the +distinction between the attribute of the divine existence of being +independent on all time-conditions, and that of a being of the world +of sense, the distinction being that between the existence of a +being in itself and that of a thing in appearance. Hence, if this +ideality of time and space is not adopted, nothing remains but +Spinozism, in which space and time are essential attributes of the +Supreme Being Himself, and the things dependent on Him (ourselves, +therefore, included) are not substances, but merely accidents inhering +in Him; since, if these things as His effects exist in time only, this +being the condition of their existence in themselves, then the actions +of these beings must be simply His actions which He performs in some +place and time. Thus, Spinozism, in spite of the absurdity of its +fundamental idea, argues more consistently than the creation theory +can, when beings assumed to be substances, and beings in themselves +existing in time, are regarded as effects of a Supreme Cause, and +yet as not [belonging] to Him and His action, but as separate +substances. + + {BOOK_1|CHAPTER_3 ^paragraph 50} + +The above-mentioned difficulty is resolved briefly and clearly as +follows: If existence in time is a mere sensible mode of +representation belonging to thinking beings in the world and +consequently does not apply to them as things in themselves, then +the creation of these beings is a creation of things in themselves, +since the notion of creation does not belong to the sensible form of +representation of existence or to causality, but can only be +referred to noumena. Consequently, when I say of beings in the world +of sense that they are created, I so far regard them as noumena. As it +would be a contradiction, therefore, to say that God is a creator of +appearances, so also it is a contradiction to say that as creator He +is the cause of actions in the world of sense, and therefore as +appearances, although He is the cause of the existence of the acting +beings (which are noumena). If now it is possible to affirm freedom in +spite of the natural mechanism of actions as appearances (by regarding +existence in time as something that belongs only to appearances, not +to things in themselves), then the circumstance that the acting beings +are creatures cannot make the slightest difference, since creation +concerns their supersensible and not their sensible existence, and, +therefore, cannot be regarded as the determining principle of the +appearances. It would be quite different if the beings in the world as +things in themselves existed in time, since in that case the creator +of substance would be at the same time the author of the whole +mechanism of this substance. + +Of so great importance is the separation of time (as well as +space) from the existence of things in themselves which was effected +in the Critique of the Pure Speculative Reason. + +It may be said that the solution here proposed involves great +difficulty in itself and is scarcely susceptible of a lucid +exposition. But is any other solution that has been attempted, or that +may be attempted, easier and more intelligible? Rather might we say +that the dogmatic teachers of metaphysics have shown more shrewdness +than candour in keeping this difficult point out of sight as much as +possible, in the hope that if they said nothing about it, probably +no one would think of it. If science is to be advanced, all +difficulties must be laid open, and we must even search for those that +are hidden, for every difficulty calls forth a remedy, which cannot be +discovered without science gaining either in extent or in exactness; +and thus even obstacles become means of increasing the thoroughness of +science. On the other hand, if the difficulties are intentionally +concealed, or merely removed by palliatives, then sooner or later they +burst out into incurable mischiefs, which bring science to ruin in +an absolute scepticism. + +Since it is, properly speaking, the notion of freedom alone amongst all +the ideas of pure speculative reason that so greatly enlarges our +knowledge in the sphere of the supersensible, though only of our +practical knowledge, I ask myself why it exclusively possesses so great +fertility, whereas the others only designate the vacant space for +possible beings of the pure understanding, but are unable by any means +to define the concept of them. I presently find that as I cannot think +anything without a category, I must first look for a category for the +rational idea of freedom with which I am now concerned; and this is the +category of causality; and although freedom, a concept of the reason, +being a transcendent concept, cannot have any intuition corresponding to +it, yet the concept of the understanding- for the synthesis of which the +former demands the unconditioned- (namely, the concept of causality) +must have a sensible intuition given, by which first its objective +reality is assured. Now, the categories are all divided into two +classes- the mathematical, which concern the unity of synthesis in the +conception of objects, and the dynamical, which refer to the unity of +synthesis in the conception of the existence of objects. The former +(those of magnitude and quality) always contain a synthesis of the +homogeneous, and it is not possible to find in this the unconditioned +antecedent to what is given in sensible intuition as conditioned in +space and time, as this would itself have to belong to space and time, +and therefore be again still conditioned. Whence it resulted in the +Dialectic of Pure Theoretic Reason that the opposite methods of +attaining the unconditioned and the totality of the conditions were both +wrong. The categories of the second class (those of causality and of the +necessity of a thing) did not require this homogeneity (of the +conditioned and the condition in synthesis), since here what we have to +explain is not how the intuition is compounded from a manifold in it, +but only how the existence of the conditioned object corresponding to it +is added to the existence of the condition (added, namely, in the +understanding as connected therewith); and in that case it was allowable +to suppose in the supersensible world the unconditioned antecedent to +the altogether conditioned in the world of sense (both as regards the +causal connection and the contingent existence of things themselves), +although this unconditioned remained indeterminate, and to make the +synthesis transcendent. Hence, it was found in the Dialectic of the Pure +Speculative Reason that the two apparently opposite methods of obtaining +for the conditioned the unconditioned were not really contradictory, +e.g., in the synthesis of causality to conceive for the conditioned in +the series of causes and effects of the sensible world, a causality +which has no sensible condition, and that the same action which, as +belonging to the world of sense, is always sensibly conditioned, that +is, mechanically necessary, yet at the same time may be derived from a +causality not sensibly conditioned- being the causality of the acting +being as belonging to the supersensible world- and may consequently be +conceived as free. Now, the only point in question was to change this +may be into is; that is, that we should be able to show in an actual +case, as it were by a fact, that certain actions imply such a causality +(namely, the intellectual, sensibly unconditioned), whether they are +actual or only commanded, that is, objectively necessary in a practical +sense. We could not hope to find this connexion in actions actually +given in experience as events of the sensible world, since causality +with freedom must always be sought outside the world of sense in the +world of intelligence. But things of sense are the only things offered +to our perception and observation. Hence, nothing remained but to find +an incontestable objective principle of causality which excludes all +sensible conditions: that is, a principle in which reason does not +appeal further to something else as a determining ground of its +causality, but contains this determining ground itself by means of that +principle, and in which therefore it is itself as pure reason practical. +Now, this principle had not to be searched for or discovered; it had +long been in the reason of all men, and incorporated in their nature, +and is the principle of morality. Therefore, that unconditioned +causality, with the faculty of it, namely, freedom, is no longer merely +indefinitely and problematically thought (this speculative reason could +prove to be feasible), but is even as regards the law of its causality +definitely and assertorially known; and with it the fact that a being (I +myself), belonging to the world of sense, belongs also to the +supersensible world, this is also positively known, and thus the reality +of the supersensible world is established and in practical respects +definitely given, and this definiteness, which for theoretical purposes +would be transcendent, is for practical purposes immanent. We could not, +however, make a similar step as regards the second dynamical idea, +namely, that of a necessary being. We could not rise to it from the +sensible world without the aid of the first dynamical idea. For if we +attempted to do so, we should have ventured to leave at a bound all that +is given to us, and to leap to that of which nothing is given us that +can help us to effect the connection of such a supersensible being with +the world of sense (since the necessary being would have to be known as +given outside ourselves). On the other hand, it is now obvious that this +connection is quite possible in relation to our own subject, inasmuch as +I know myself to be on the one side as an intelligible [supersensible] +being determined by the moral law (by means of freedom), and on the +other side as acting in the world of sense. It is the concept of freedom +alone that enables us to find the unconditioned and intelligible for the +conditioned and sensible without going out of ourselves. For it is our +own reason that by means of the supreme and unconditional practical law +knows that itself and the being that is conscious of this law (our own +person) belong to the pure world of understanding, and moreover defines +the manner in which, as such, it can be active. In this way it can be +understood why in the whole faculty of reason it is the practical reason +only that can help us to pass beyond the world of sense and give us +knowledge of a supersensible order and connection, which, however, for +this very reason cannot be extended further than is necessary for pure +practical purposes. + +Let me be permitted on this occasion to make one more remark, +namely, that every step that we make with pure reason, even in the +practical sphere where no attention is paid to subtle speculation, +nevertheless accords with all the material points of the Critique of +the Theoretical Reason as closely and directly as if each step had +been thought out with deliberate purpose to establish this +confirmation. Such a thorough agreement, wholly unsought for and quite +obvious (as anyone can convince himself, if he will only carry moral +inquiries up to their principles), between the most important +proposition of practical reason and the often seemingly too subtle and +needless remarks of the Critique of the Speculative Reason, +occasions surprise and astonishment, and confirms the maxim already +recognized and praised by others, namely, that in every scientific +inquiry we should pursue our way steadily with all possible +exactness and frankness, without caring for any objections that may be +raised from outside its sphere, but, as far as we can, to carry out +our inquiry truthfully and completely by itself. Frequent +observation has convinced me that, when such researches are concluded, +that which in one part of them appeared to me very questionable, +considered in relation to other extraneous doctrines, when I left this +doubtfulness out of sight for a time and only attended to the business +in hand until it was completed, at last was unexpectedly found to +agree perfectly with what had been discovered separately without the +least regard to those doctrines, and without any partiality or +prejudice for them. Authors would save themselves many errors and much +labour lost (because spent on a delusion) if they could only resolve +to go to work with more frankness. + +BOOK_2|CHAPTER_1 + + BOOK II. Dialectic of Pure Practical Reason. + + + +CHAPTER I. Of a Dialectic of Pure Practical Reason Generally. + + + +Pure reason always has its dialetic, whether it is considered in its +speculative or its practical employment; for it requires the +absolute totality of the 'conditions of what is given conditioned, and +this can only be found in things in themselves. But as all conceptions +of things in themselves must be referred to intuitions, and with us +men these can never be other than sensible and hence can never +enable us to know objects as things in themselves but only as +appearances, and since the unconditioned can never be found in this +chain of appearances which consists only of conditioned and +conditions; thus from applying this rational idea of the totality of +the conditions (in other words of the unconditioned) to appearances, +there arises an inevitable illusion, as if these latter were things in +themselves (for in the absence of a warning critique they are always +regarded as such). This illusion would never be noticed as delusive if +it did not betray itself by a conflict of reason with itself, when +it applies to appearances its fundamental principle of presupposing +the unconditioned to everything conditioned. By this, however, +reason is compelled to trace this illusion to its source, and search +how it can be removed, and this can only be done by a complete +critical examination of the whole pure faculty of reason; so that +the antinomy of the pure reason which is manifest in its dialectic +is in fact the most beneficial error into which human reason could +ever have fallen, since it at last drives us to search for the key +to escape from this labyrinth; and when this key is found, it +further discovers that which we did not seek but yet had need of, +namely, a view into a higher and an immutable order of things, in +which we even now are, and in which we are thereby enabled by definite +precepts to continue to live according to the highest dictates of +reason. + +It may be seen in detail in the Critique of Pure Reason how in its +speculative employment this natural dialectic is to be solved, and how +the error which arises from a very natural illusion may be guarded +against. But reason in its practical use is not a whit better off. +As pure practical reason, it likewise seeks to find the +unconditioned for the practically conditioned (which rests on +inclinations and natural wants), and this is not as the determining +principle of the will, but even when this is given (in the moral +law) it seeks the unconditioned totality of the object of pure +practical reason under the name of the summum bonum. + +To define this idea practically, i.e., sufficiently for the maxims +of our rational conduct, is the business of practical wisdom, and this +again as a science is philosophy, in the sense in which the word was +understood by the ancients, with whom it meant instruction in the +conception in which the summum bonum was to be placed, and the conduct +by which it was to be obtained. It would be well to leave this word in +its ancient signification as a doctrine of the summum bonum, so far as +reason endeavours to make this into a science. For on the one hand the +restriction annexed would suit the Greek expression (which signifies +the love of wisdom), and yet at the same time would be sufficient to +embrace under the name of philosophy the love of science: that is to +say, of all speculative rational knowledge, so far as it is +serviceable to reason, both for that conception and also for the +practical principle determining our conduct, without letting out of +sight the main end, on account of which alone it can be called a +doctrine of practical wisdom. On the other hand, it would be no harm +to deter the self-conceit of one who ventures to claim the title of +philosopher by holding before him in the very definition a standard of +self-estimation which would very much lower his pretensions. For a +teacher of wisdom would mean something more than a scholar who has not +come so far as to guide himself, much less to guide others, with +certain expectation of attaining so high an end: it would mean a +master in the knowledge of wisdom, which implies more than a modest +man would claim for himself. Thus philosophy as well as wisdom would +always remain an ideal, which objectively is presented complete in +reason alone, while subjectively for the person it is only the goal of +his unceasing endeavours; and no one would be justified in +professing to be in possession of it so as to assume the name of +philosopher who could not also show its infallible effects in his +own person as an example (in his self-mastery and the unquestioned +interest that he takes pre-eminently in the general good), and this +the ancients also required as a condition of deserving that honourable +title. + + {BOOK_2|CHAPTER_1 ^paragraph 5} + +We have another preliminary remark to make respecting the +dialectic of the pure practical reason, on the point of the definition +of the summum bonum (a successful solution of which dialectic would +lead us to expect, as in case of that of the theoretical reason, the +most beneficial effects, inasmuch as the self-contradictions of pure +practical reason honestly stated, and not concealed, force us to +undertake a complete critique of this faculty). + +The moral law is the sole determining principle of a pure will. +But since this is merely formal (viz., as prescribing only the form of +the maxim as universally legislative), it abstracts as a determining +principle from all matter that is to say, from every object of +volition. Hence, though the summum bonum may be the whole object of +a pure practical reason, i.e., a pure will, yet it is not on that +account to be regarded as its determining principle; and the moral law +alone must be regarded as the principle on which that and its +realization or promotion are aimed at. This remark is important in +so delicate a case as the determination of moral principles, where the +slightest misinterpretation perverts men's minds. For it will have +been seen from the Analytic that, if we assume any object under the +name of a good as a determining principle of the will prior to the +moral law and then deduce from it the supreme practical principle, +this would always introduce heteronomy and crush out the moral +principle. + +It is, however, evident that if the notion of the summum bonum +includes that of the moral law as its supreme condition, then the +summum bonum would not merely be an object, but the notion of it and +the conception of its existence as possible by our own practical +reason would likewise be the determining principle of the will, +since in that case the will is in fact determined by the moral law +which is already included in this conception, and by no other +object, as the principle of autonomy requires. This order of the +conceptions of determination of the will must not be lost sight of, as +otherwise we should misunderstand ourselves and think we had fallen +into a contradiction, while everything remains in perfect harmony. + +BOOK_2|CHAPTER_2 + + CHAPTER II. Of the Dialectic of Pure Reason in defining the + + Conception of the "Summum Bonum". + + + +The conception of the summum itself contains an ambiguity which +might occasion needless disputes if we did not attend to it. The +summum may mean either the supreme (supremum) or the perfect +(consummatum). The former is that condition which is itself +unconditioned, i.e., is not subordinate to any other (originarium); +the second is that whole which is not a part of a greater whole of the +same kind (perfectissimum). It has been shown in the Analytic that +virtue (as worthiness to be happy) is the supreme condition of all +that can appear to us desirable, and consequently of all our pursuit +of happiness, and is therefore the supreme good. But it does not +follow that it is the whole and perfect good as the object of the +desires of rational finite beings; for this requires happiness also, +and that not merely in the partial eyes of the person who makes +himself an end, but even in the judgement of an impartial reason, +which regards persons in general as ends in themselves. For to need +happiness, to deserve it, and yet at the same time not to +participate in it, cannot be consistent with the perfect volition of a +rational being possessed at the same time of all power, if, for the +sake of experiment, we conceive such a being. Now inasmuch as virtue +and happiness together constitute the possession of the summum bonum +in a person, and the distribution of happiness in exact proportion +to morality (which is the worth of the person, and his worthiness to +be happy) constitutes the summum bonum of a possible world; hence this +summum bonum expresses the whole, the perfect good, in which, however, +virtue as the condition is always the supreme good, since it has no +condition above it; whereas happiness, while it is pleasant to the +possessor of it, is not of itself absolutely and in all respects good, +but always presupposes morally right behaviour as its condition. + +When two elements are necessarily united in one concept, they must +be connected as reason and consequence, and this either so that +their unity is considered as analytical (logical connection), or as +synthetical (real connection) the former following the law of +identity, the latter that of causality. The connection of virtue and +happiness may therefore be understood in two ways: either the +endeavour to be virtuous and the rational pursuit of happiness are not +two distinct actions, but absolutely identical, in which case no maxim +need be made the principle of the former, other than what serves for +the latter; or the connection consists in this, that virtue produces +happiness as something distinct from the consciousness of virtue, as a +cause produces an effect. + +The ancient Greek schools were, properly speaking, only two, and +in determining the conception of the summum bonum these followed in +fact one and the same method, inasmuch as they did not allow virtue +and happiness to be regarded as two distinct elements of the summum +bonum, and consequently sought the unity of the principle by the +rule of identity; but they differed as to which of the two was to be +taken as the fundamental notion. The Epicurean said: "To be +conscious that one's maxims lead to happiness is virtue"; the Stoic +said: "To be conscious of one's virtue is happiness." With the former, +Prudence was equivalent to morality; with the latter, who chose a +higher designation for virtue, morality alone was true wisdom. + +While we must admire the men who in such early times tried all +imaginable ways of extending the domain of philosophy, we must at +the same time lament that their acuteness was unfortunately misapplied +in trying to trace out identity between two extremely heterogeneous +notions, those of happiness and virtue. But it agrees with the +dialectical spirit of their times (and subtle minds are even now +sometimes misled in the same way) to get rid of irreconcilable +differences in principle by seeking to change them into a mere contest +about words, and thus apparently working out the identity of the +notion under different names, and this usually occurs in cases where +the combination of heterogeneous principles lies so deep or so high, +or would require so complete a transformation of the doctrines assumed +in the rest of the philosophical system, that men are afraid to +penetrate deeply into the real difference and prefer treating it as +a difference in questions of form. + + {BOOK_2|CHAPTER_2 ^paragraph 5} + +While both schools sought to trace out the identity of the practical +principles of virtue and happiness, they were not agreed as to the way +in which they tried to force this identity, but were separated +infinitely from one another, the one placing its principle on the side +of sense, the other on that of reason; the one in the consciousness of +sensible wants, the other in the independence of practical reason on +all sensible grounds of determination. According to the Epicurean, the +notion of virtue was already involved in the maxim: "To promote +one's own happiness"; according to the Stoics, on the other hand, +the feeling of happiness was already contained in the consciousness of +virtue. Now whatever is contained in another notion is identical +with part of the containing notion, but not with the whole, and +moreover two wholes may be specifically distinct, although they +consist of the same parts; namely if the parts are united into a whole +in totally different ways. The Stoic maintained that the virtue was +the whole summum bonum, and happiness only the consciousness of +possessing it, as making part of the state of the subject. The +Epicurean maintained that happiness was the whole summum bonum, and +virtue only the form of the maxim for its pursuit; viz., the +rational use of the means for attaining it. + +Now it is clear from the Analytic that the maxims of virtue and +those of private happiness are quite heterogeneous as to their supreme +practical principle, and, although they belong to one summum bonum +which together they make possible, yet they are so far from coinciding +that they restrict and check one another very much in the same +subject. Thus the question: "How is the summum bonum practically +possible?" still remains an unsolved problem, notwithstanding all +the attempts at coalition that have hitherto been made. The Analytic +has, however, shown what it is that makes the problem difficult to +solve; namely, that happiness and morality are two specifically +distinct elements of the summum bonum and, therefore, their +combination cannot be analytically cognised (as if the man that +seeks his own happiness should find by mere analysis of his conception +that in so acting he is virtuous, or as if the man that follows virtue +should in the consciousness of such conduct find that he is already +happy ipso facto), but must be a synthesis of concepts. Now since this +combination is recognised as a priori, and therefore as practically +necessary, and consequently not as derived from experience, so that +the possibility of the summum bonum does not rest on any empirical +principle, it follows that the deduction [legitimation] of this +concept must be transcendental. It is a priori (morally) necessary +to produce the summum bonum by freedom of will: therefore the +condition of its possibility must rest solely on a priori principles +of cognition. + + + + I. The Antinomy of Practical Reason. + + + + {BOOK_2|CHAPTER_2 ^paragraph 10} + +In the summum bonum which is practical for us, i.e., to be +realized by our will, virtue and happiness are thought as +necessarily combined, so that the one cannot be assumed by pure +practical reason without the other also being attached to it. Now this +combination (like every other) is either analytical or synthetical. It +has been shown that it cannot be analytical; it must then be +synthetical and, more particularly, must be conceived as the +connection of cause and effect, since it concerns a practical good, +i.e., one that is possible by means of action; consequently either the +desire of happiness must be the motive to maxims of virtue, or the +maxim of virtue must be the efficient cause of happiness. The first is +absolutely impossible, because (as was proved in the Analytic) +maxims which place the determining principle of the will in the desire +of personal happiness are not moral at all, and no virtue can be +founded on them. But the second is also impossible, because the +practical connection of causes and effects in the world, as the result +of the determination of the will, does not depend upon the moral +dispositions of the will, but on the knowledge of the laws of nature +and the physical power to use them for one's purposes; consequently we +cannot expect in the world by the most punctilious observance of the +moral laws any necessary connection of happiness with virtue +adequate to the summum bonum. Now, as the promotion of this summum +bonum, the conception of which contains this connection, is a priori a +necessary object of our will and inseparably attached to the moral +law, the impossibility of the former must prove the falsity of the +latter. If then the supreme good is not possible by practical rules, +then the moral law also which commands us to promote it is directed to +vain imaginary ends and must consequently be false. + + + + II. Critical Solution of the Antinomy of Practical Reason. + + + +The antinomy of pure speculative reason exhibits a similar +conflict between freedom and physical necessity in the causality of +events in the world. It was solved by showing that there is no real +contradiction when the events and even the world in which they occur +are regarded (as they ought to be) merely as appearances; since one +and the same acting being, as an appearance (even to his own inner +sense), has a causality in the world of sense that always conforms +to the mechanism of nature, but with respect to the same events, so +far as the acting person regards himself at the same time as a +noumenon (as pure intelligence in an existence not dependent on the +condition of time), he can contain a principle by which that causality +acting according to laws of nature is determined, but which is +itself free from all laws of nature. + + {BOOK_2|CHAPTER_2 ^paragraph 15} + +It is just the same with the foregoing antinomy of pure practical +reason. The first of the two propositions, "That the endeavour after +happiness produces a virtuous mind," is absolutely false; but the +second, "That a virtuous mind necessarily produces happiness," is +not absolutely false, but only in so far as virtue is considered as +a form of causality in the sensible world, and consequently only if +I suppose existence in it to be the only sort of existence of a +rational being; it is then only conditionally false. But as I am not +only justified in thinking that I exist also as a noumenon in a +world of the understanding, but even have in the moral law a purely +intellectual determining principle of my causality (in the sensible +world), it is not impossible that morality of mind should have a +connection as cause with happiness (as an effect in the sensible +world) if not immediate yet mediate (viz., through an intelligent +author of nature), and moreover necessary; while in a system of nature +which is merely an object of the senses, this combination could +never occur except contingently and, therefore, could not suffice +for the summum bonum. + +Thus, notwithstanding this seeming conflict of practical reason with +itself, the summum bonum, which is the necessary supreme end of a will +morally determined, is a true object thereof; for it is practically +possible, and the maxims of the will which as regards their matter +refer to it have objective reality, which at first was threatened by +the antinomy that appeared in the connection of morality with +happiness by a general law; but this was merely from a +misconception, because the relation between appearances was taken +for a relation of the things in themselves to these appearances. + +When we find ourselves obliged to go so far, namely, to the +connection with an intelligible world, to find the possibility of +the summum bonum, which reason points out to all rational beings as +the goal of all their moral wishes, it must seem strange that, +nevertheless, the philosophers both of ancient and modern times have +been able to find happiness in accurate proportion to virtue even in +this life (in the sensible world), or have persuaded themselves that +they were conscious thereof. For Epicurus as well as the Stoics +extolled above everything the happiness that springs from the +consciousness of living virtuously; and the former was not so base +in his practical precepts as one might infer from the principles of +his theory, which he used for explanation and not for action, or as +they were interpreted by many who were misled by his using the term +pleasure for contentment; on the contrary, he reckoned the most +disinterested practice of good amongst the ways of enjoying the most +intimate delight, and his scheme of pleasure (by which he meant +constant cheerfulness of mind) included the moderation and control +of the inclinations, such as the strictest moral philosopher might +require. He differed from the Stoics chiefly in making this pleasure +the motive, which they very rightly refused to do. For, on the one +hand, the virtuous Epicurus, like many well-intentioned men of this +day who do not reflect deeply enough on their principles, fell into +the error of presupposing the virtuous disposition in the persons +for whom he wished to provide the springs to virtue (and indeed the +upright man cannot be happy if he is not first conscious of his +uprightness; since with such a character the reproach that his habit +of thought would oblige him to make against himself in case of +transgression and his moral self-condemnation would rob him of all +enjoyment of the pleasantness which his condition might otherwise +contain). But the question is: How is such a disposition possible in +the first instance, and such a habit of thought in estimating the +worth of one's existence, since prior to it there can be in the +subject no feeling at all for moral worth? If a man is virtuous +without being conscious of his integrity in every action, he will +certainly not enjoy life, however favourable fortune may be to him +in its physical circumstances; but can we make him virtuous in the +first instance, in other words, before he esteems the moral worth of +his existence so highly, by praising to him the peace of mind that +would result from the consciousness of an integrity for which he has +no sense? + +On the other hand, however, there is here an occasion of a vitium +subreptionis, and as it were of an optical illusion, in the +self-consciousness of what one does as distinguished from what one +feels- an illusion which even the most experienced cannot altogether +avoid. The moral disposition of mind is necessarily combined with a +consciousness that the will is determined directly by the law. Now the +consciousness of a determination of the faculty of desire is always +the source of a satisfaction in the resulting action; but this +pleasure, this satisfaction in oneself, is not the determining +principle of the action; on the contrary, the determination of the +will directly by reason is the source of the feeling of pleasure, +and this remains a pure practical not sensible determination of the +faculty of desire. Now as this determination has exactly the same +effect within in impelling to activity, that a feeling of the pleasure +to be expected from the desired action would have had, we easily +look on what we ourselves do as something which we merely passively +feel, and take the moral spring for a sensible impulse, just as it +happens in the so-called illusion of the senses (in this case the +inner sense). It is a sublime thing in human nature to be determined +to actions immediately by a purely rational law; sublime even is the +illusion that regards the subjective side of this capacity of +intellectual determination as something sensible and the effect of a +special sensible feeling (for an intellectual feeling would be a +contradiction). It is also of great importance to attend to this +property of our personality and as much as possible to cultivate the +effect of reason on this feeling. But we must beware lest by falsely +extolling this moral determining principle as a spring, making its +source lie in particular feelings of pleasure (which are in fact +only results), we degrade and disfigure the true genuine spring, the +law itself, by putting as it were a false foil upon it. Respect, not +pleasure or enjoyment of happiness, is something for which it is not +possible that reason should have any antecedent feeling as its +foundation (for this would always be sensible and pathological); and +consciousness of immediate obligation of the will by the law is by +no means analogous to the feeling of pleasure, although in relation to +the faculty of desire it produces the same effect, but from +different sources: it is only by this mode of conception, however, +that we can attain what we are seeking, namely, that actions be done +not merely in accordance with duty (as a result of pleasant feelings), +but from duty, which must be the true end of all moral cultivation. + +Have we not, however, a word which does not express enjoyment, as +happiness does, but indicates a satisfaction in one's existence, an +analogue of the happiness which must necessarily accompany the +consciousness of virtue? Yes this word is self-contentment which in +its proper signification always designates only a negative +satisfaction in one's existence, in which one is conscious of +needing nothing. Freedom and the consciousness of it as a faculty of +following the moral law with unyielding resolution is independence +of inclinations, at least as motives determining (though not as +affecting) our desire, and so far as I am conscious of this freedom in +following my moral maxims, it is the only source of an unaltered +contentment which is necessarily connected with it and rests on no +special feeling. This may be called intellectual contentment. The +sensible contentment (improperly so-called) which rests on the +satisfaction of the inclinations, however delicate they may be +imagined to be, can never be adequate to the conception of it. For the +inclinations change, they grow with the indulgence shown them, and +always leave behind a still greater void than we had thought to +fill. Hence they are always burdensome to a rational being, and, +although he cannot lay them aside, they wrest from him the wish to +be rid of them. Even an inclination to what is right (e.g., to +beneficence), though it may much facilitate the efficacy of the +moral maxims, cannot produce any. For in these all must be directed to +the conception of the law as a determining principle, if the action is +to contain morality and not merely legality. Inclination is blind +and slavish, whether it be of a good sort or not, and, when morality +is in question, reason must not play the part merely of guardian to +inclination, but disregarding it altogether must attend simply to +its own interest as pure practical reason. This very feeling of +compassion and tender sympathy, if it precedes the deliberation on the +question of duty and becomes a determining principle, is even annoying +to right thinking persons, brings their deliberate maxims into +confusion, and makes them wish to be delivered from it and to be +subject to lawgiving reason alone. + + {BOOK_2|CHAPTER_2 ^paragraph 20} + +From this we can understand how the consciousness of this faculty of +a pure practical reason produces by action (virtue) a consciousness of +mastery over one's inclinations, and therefore of independence of +them, and consequently also of the discontent that always +accompanies them, and thus a negative satisfaction with one's state, +i.e., contentment, which is primarily contentment with one's own +person. Freedom itself becomes in this way (namely, indirectly) +capable of an enjoyment which cannot be called happiness, because it +does not depend on the positive concurrence of a feeling, nor is it, +strictly speaking, bliss, since it does not include complete +independence of inclinations and wants, but it resembles bliss in so +far as the determination of one's will at least can hold itself free +from their influence; and thus, at least in its origin, this enjoyment +is analogous to the self-sufficiency which we can ascribe only to +the Supreme Being. + +From this solution of the antinomy of practical pure reason, it +follows that in practical principles we may at least conceive as +possible a natural and necessary connection between the +consciousness of morality and the expectation of a proportionate +happiness as its result, though it does not follow that we can know or +perceive this connection; that, on the other hand, principles of the +pursuit of happiness cannot possibly produce morality; that, +therefore, morality is the supreme good (as the first condition of the +summum bonum), while happiness constitutes its second element, but +only in such a way that it is the morally conditioned, but necessary +consequence of the former. Only with this subordination is the +summum bonum the whole object of pure practical reason, which must +necessarily conceive it as possible, since it commands us to +contribute to the utmost of our power to its realization. But since +the possibility of such connection of the conditioned with its +condition belongs wholly to the supersensual relation of things and +cannot be given according to the laws of the world of sense, +although the practical consequences of the idea belong to the world of +sense, namely, the actions that aim at realizing the summum bonum; +we will therefore endeavour to set forth the grounds of that +possibility, first, in respect of what is immediately in our power, +and then, secondly, in that which is not in our power, but which +reason presents to us as the supplement of our impotence, for the +realization of the summum bonum (which by practical principles is +necessary). + + + + III. Of the Primacy of Pure Practical Reason in its + + Union with the Speculative Reason. + + {BOOK_2|CHAPTER_2 ^paragraph 25} + + + +By primacy between two or more things connected by reason, I +understand the prerogative, belonging to one, of being the first +determining principle in the connection with all the rest. In a +narrower practical sense it means the prerogative of the interest of +one in so far as the interest of the other is subordinated to it, +while it is not postponed to any other. To every faculty of the mind +we can attribute an interest, that is, a principle, that contains +the condition on which alone the former is called into exercise. +Reason, as the faculty of principles, determines the interest of all +the powers of the mind and is determined by its own. The interest of +its speculative employment consists in the cognition of the object +pushed to the highest a priori principles: that of its practical +employment, in the determination of the will in respect of the final +and complete end. As to what is necessary for the possibility of any +employment of reason at all, namely, that its principles and +affirmations should not contradict one another, this constitutes no +part of its interest, but is the condition of having reason at all; it +is only its development, not mere consistency with itself, that is +reckoned as its interest. + +If practical reason could not assume or think as given anything +further than what speculative reason of itself could offer it from its +own insight, the latter would have the primacy. But supposing that +it had of itself original a priori principles with which certain +theoretical positions were inseparably connected, while these were +withdrawn from any possible insight of speculative reason (which, +however, they must not contradict); then the question is: Which +interest is the superior (not which must give way, for they are not +necessarily conflicting), whether speculative reason, which knows +nothing of all that the practical offers for its acceptance, should +take up these propositions and (although they transcend it) try to +unite them with its own concepts as a foreign possession handed over +to it, or whether it is justified in obstinately following its own +separate interest and, according to the canonic of Epicurus, rejecting +as vain subtlety everything that cannot accredit its objective reality +by manifest examples to be shown in experience, even though it +should be never so much interwoven with the interest of the +practical (pure) use of reason, and in itself not contradictory to the +theoretical, merely because it infringes on the interest of the +speculative reason to this extent, that it removes the bounds which +this latter had set to itself, and gives it up to every nonsense or +delusion of imagination? + +In fact, so far as practical reason is taken as dependent on +pathological conditions, that is, as merely regulating the +inclinations under the sensible principle of happiness, we could not +require speculative reason to take its principles from such a +source. Mohammed's paradise, or the absorption into the Deity of the +theosophists and mystics would press their monstrosities on the reason +according to the taste of each, and one might as well have no reason +as surrender it in such fashion to all sorts of dreams. But if pure +reason of itself can be practical and is actually so, as the +consciousness of the moral law proves, then it is still only one and +the same reason which, whether in a theoretical or a practical point +of view, judges according to a priori principles; and then it is clear +that although it is in the first point of view incompetent to +establish certain propositions positively, which, however, do not +contradict it, then, as soon as these propositions are inseparably +attached to the practical interest of pure reason, it must accept +them, though it be as something offered to it from a foreign source, +something that has not grown on its own ground, but yet is +sufficiently authenticated; and it must try to compare and connect +them with everything that it has in its power as speculative reason. +It must remember, however, that these are not additions to its +insight, but yet are extensions of its employment in another, +namely, a practical aspect; and this is not in the least opposed to +its interest, which consists in the restriction of wild speculation. + +Thus, when pure speculative and pure practical reason are combined +in one cognition, the latter has the primacy, provided, namely, that +this combination is not contingent and arbitrary, but founded a priori +on reason itself and therefore necessary. For without this +subordination there would arise a conflict of reason with itself; +since, if they were merely co-ordinate, the former would close its +boundaries strictly and admit nothing from the latter into its domain, +while the latter would extend its bounds over everything and when +its needs required would seek to embrace the former within them. Nor +could we reverse the order and require pure practical reason to be +subordinate to the speculative, since all interest is ultimately +practical, and even that of speculative reason is conditional, and +it is only in the practical employment of reason that it is complete. + + {BOOK_2|CHAPTER_2 ^paragraph 30} + + + + IV. The Immortality of the Soul as a Postulate of + + Pure Practical Reason. + + + +The realization of the summum bonum in the world is the necessary +object of a will determinable by the moral law. But in this will the +perfect accordance of the mind with the moral law is the supreme +condition of the summum bonum. This then must be possible, as well +as its object, since it is contained in the command to promote the +latter. Now, the perfect accordance of the will with the moral law +is holiness, a perfection of which no rational being of the sensible +world is capable at any moment of his existence. Since, +nevertheless, it is required as practically necessary, it can only +be found in a progress in infinitum towards that perfect accordance, +and on the principles of pure practical reason it is necessary to +assume such a practical progress as the real object of our will. + + {BOOK_2|CHAPTER_2 ^paragraph 35} + +Now, this endless progress is only possible on the supposition of an +endless duration of the existence and personality of the same rational +being (which is called the immortality of the soul). The summum bonum, +then, practically is only possible on the supposition of the +immortality of the soul; consequently this immortality, being +inseparably connected with the moral law, is a postulate of pure +practical reason (by which I mean a theoretical proposition, not +demonstrable as such, but which is an inseparable result of an +unconditional a priori practical law. + +This principle of the moral destination of our nature, namely, +that it is only in an endless progress that we can attain perfect +accordance with the moral law, is of the greatest use, not merely +for the present purpose of supplementing the impotence of +speculative reason, but also with respect to religion. In default of +it, either the moral law is quite degraded from its holiness, being +made out to be indulgent and conformable to our convenience, or else +men strain their notions of their vocation and their expectation to an +unattainable goal, hoping to acquire complete holiness of will, and so +they lose themselves in fanatical theosophic dreams, which wholly +contradict self-knowledge. In both cases the unceasing effort to +obey punctually and thoroughly a strict and inflexible command of +reason, which yet is not ideal but real, is only hindered. For a +rational but finite being, the only thing possible is an endless +progress from the lower to higher degrees of moral perfection. The +Infinite Being, to whom the condition of time is nothing, sees in this +to us endless succession a whole of accordance with the moral law; and +the holiness which his command inexorably requires, in order to be +true to his justice in the share which He assigns to each in the +summum bonum, is to be found in a single intellectual intuition of the +whole existence of rational beings. All that can be expected of the +creature in respect of the hope of this participation would be the +consciousness of his tried character, by which from the progress he +has hitherto made from the worse to the morally better, and the +immutability of purpose which has thus become known to him, he may +hope for a further unbroken continuance of the same, however long +his existence may last, even beyond this life, * and thus he may +hope, not indeed here, nor in any imaginable point of his future +existence, but only in the endlessness of his duration (which God +alone can survey) to be perfectly adequate to his will (without +indulgence or excuse, which do not harmonize with justice). + + + +* It seems, nevertheless, impossible for a creature to have the +conviction of his unwavering firmness of mind in the progress +towards goodness. On this account the Christian religion makes it come +only from the same Spirit that works sanctification, that is, this +firm purpose, and with it the consciousness of steadfastness in the +moral progress. But naturally one who is conscious that he has +persevered through a long portion of his life up to the end in the +progress to the better, and this genuine moral motives, may well +have the comforting hope, though not the certainty, that even in an +existence prolonged beyond this life he will continue in these +principles; and although he is never justified here in his own eyes, +nor can ever hope to be so in the increased perfection of his +nature, to which he looks forward, together with an increase of +duties, nevertheless in this progress which, though it is directed +to a goal infinitely remote, yet is in God's sight regarded as +equivalent to possession, he may have a prospect of a blessed +future; for this is the word that reason employs to designate +perfect well-being independent of all contingent causes of the +world, and which, like holiness, is an idea that can be contained only +in an endless progress and its totality, and consequently is never +fully attained by a creature. + + + + {BOOK_2|CHAPTER_2 ^paragraph 40} + +V. The Existence of God as a Postulate of Pure Practical Reason. + + + +In the foregoing analysis the moral law led to a practical problem +which is prescribed by pure reason alone, without the aid of any +sensible motives, namely, that of the necessary completeness of the +first and principle element of the summum bonum, viz., morality; +and, as this can be perfectly solved only in eternity, to the +postulate of immortality. The same law must also lead us to affirm the +possibility of the second element of the summum bonum, viz., happiness +proportioned to that morality, and this on grounds as disinterested as +before, and solely from impartial reason; that is, it must lead to the +supposition of the existence of a cause adequate to this effect; in +other words, it must postulate the existence of God, as the +necessary condition of the possibility of the summum bonum (an +object of the will which is necessarily connected with the moral +legislation of pure reason). We proceed to exhibit this connection +in a convincing manner. + +Happiness is the condition of a rational being in the world with +whom everything goes according to his wish and will; it rests, +therefore, on the harmony of physical nature with his whole end and +likewise with the essential determining principle of his will. Now the +moral law as a law of freedom commands by determining principles, +which ought to be quite independent of nature and of its harmony +with our faculty of desire (as springs). But the acting rational being +in the world is not the cause of the world and of nature itself. There +is not the least ground, therefore, in the moral law for a necessary +connection between morality and proportionate happiness in a being +that belongs to the world as part of it, and therefore dependent on +it, and which for that reason cannot by his will be a cause of this +nature, nor by his own power make it thoroughly harmonize, as far as +his happiness is concerned, with his practical principles. +Nevertheless, in the practical problem of pure reason, i.e., the +necessary pursuit of the summum bonum, such a connection is postulated +as necessary: we ought to endeavour to promote the summum bonum, +which, therefore, must be possible. Accordingly, the existence of a +cause of all nature, distinct from nature itself and containing the +principle of this connection, namely, of the exact harmony of +happiness with morality, is also postulated. Now this supreme cause +must contain the principle of the harmony of nature, not merely with a +law of the will of rational beings, but with the conception of this +law, in so far as they make it the supreme determining principle of +the will, and consequently not merely with the form of morals, but +with their morality as their motive, that is, with their moral +character. Therefore, the summum bonum is possible in the world only +on the supposition of a Supreme Being having a causality corresponding +to moral character. Now a being that is capable of acting on the +conception of laws is an intelligence (a rational being), and the +causality of such a being according to this conception of laws is +his will; therefore the supreme cause of nature, which must be +presupposed as a condition of the summum bonum is a being which is the +cause of nature by intelligence and will, consequently its author, +that is God. It follows that the postulate of the possibility of the +highest derived good (the best world) is likewise the postulate of the +reality of a highest original good, that is to say, of the existence +of God. Now it was seen to be a duty for us to promote the summum +bonum; consequently it is not merely allowable, but it is a +necessity connected with duty as a requisite, that we should +presuppose the possibility of this summum bonum; and as this is +possible only on condition of the existence of God, it inseparably +connects the supposition of this with duty; that is, it is morally +necessary to assume the existence of God. + +It must be remarked here that this moral necessity is subjective, +that is, it is a want, and not objective, that is, itself a duty, +for there cannot be a duty to suppose the existence of anything (since +this concerns only the theoretical employment of reason). Moreover, it +is not meant by this that it is necessary to suppose the existence +of God as a basis of all obligation in general (for this rests, as has +been sufficiently proved, simply on the autonomy of reason itself). +What belongs to duty here is only the endeavour to realize and promote +the summum bonum in the world, the possibility of which can +therefore be postulated; and as our reason finds it not conceivable +except on the supposition of a supreme intelligence, the admission +of this existence is therefore connected with the consciousness of our +duty, although the admission itself belongs to the domain of +speculative reason. Considered in respect of this alone, as a +principle of explanation, it may be called a hypothesis, but in +reference to the intelligibility of an object given us by the moral +law (the summum bonum), and consequently of a requirement for +practical purposes, it may be called faith, that is to say a pure +rational faith, since pure reason (both in its theoretical and +practical use) is the sole source from which it springs. + + {BOOK_2|CHAPTER_2 ^paragraph 45} + +From this deduction it is now intelligible why the Greek schools +could never attain the solution of their problem of the practical +possibility of the summum bonum, because they made the rule of the use +which the will of man makes of his freedom the sole and sufficient +ground of this possibility, thinking that they had no need for that +purpose of the existence of God. No doubt they were so far right +that they established the principle of morals of itself +independently of this postulate, from the relation of reason only to +the will, and consequently made it the supreme practical condition +of the summum bonum; but it was not therefore the whole condition of +its possibility. The Epicureans had indeed assumed as the supreme +principle of morality a wholly false one, namely that of happiness, +and had substituted for a law a maxim of arbitrary choice according to +every man's inclination; they proceeded, however, consistently +enough in this, that they degraded their summum bonum likewise, just +in proportion to the meanness of their fundamental principle, and +looked for no greater happiness than can be attained by human prudence +(including temperance and moderation of the inclinations), and this as +we know would be scanty enough and would be very different according +to circumstances; not to mention the exceptions that their maxims must +perpetually admit and which make them incapable of being laws. The +Stoics, on the contrary, had chosen their supreme practical +principle quite rightly, making virtue the condition of the summum +bonum; but when they represented the degree of virtue required by +its pure law as fully attainable in this life, they not only +strained the moral powers of the man whom they called the wise +beyond all the limits of his nature, and assumed a thing that +contradicts all our knowledge of men, but also and principally they +would not allow the second element of the summum bonum, namely, +happiness, to be properly a special object of human desire, but made +their wise man, like a divinity in his consciousness of the excellence +of his person, wholly independent of nature (as regards his own +contentment); they exposed him indeed to the evils of life, but made +him not subject to them (at the same time representing him also as +free from moral evil). They thus, in fact, left out the second element +of the summum bonum namely, personal happiness, placing it solely in +action and satisfaction with one's own personal worth, thus +including it in the consciousness of being morally minded, in which +they Might have been sufficiently refuted by the voice of their own +nature. + +The doctrine of Christianity, * even if we do not yet consider it +as a religious doctrine, gives, touching this point, a conception of +the summum bonum (the kingdom of God), which alone satisfies the +strictest demand of practical reason. The moral law is holy +(unyielding) and demands holiness of morals, although all the moral +perfection to which man can attain is still only virtue, that is, a +rightful disposition arising from respect for the law, implying +consciousness of a constant propensity to transgression, or at least a +want of purity, that is, a mixture of many spurious (not moral) +motives of obedience to the law, consequently a self-esteem combined +with humility. In respect, then, of the holiness which the Christian +law requires, this leaves the creature nothing but a progress in +infinitum, but for that very reason it justifies him in hoping for +an endless duration of his existence. The worth of a character +perfectly accordant with the moral law is infinite, since the only +restriction on all possible happiness in the judgement of a wise and +all powerful distributor of it is the absence of conformity of +rational beings to their duty. But the moral law of itself does not +promise any happiness, for according to our conceptions of an order of +nature in general, this is not necessarily connected with obedience to +the law. Now Christian morality supplies this defect (of the second +indispensable element of the summum bonum) by representing the world +in which rational beings devote themselves with all their soul to +the moral law, as a kingdom of God, in which nature and morality are +brought into a harmony foreign to each of itself, by a holy Author who +makes the derived summum bonum possible. Holiness of life is +prescribed to them as a rule even in this life, while the welfare +proportioned to it, namely, bliss, is represented as attainable only +in an eternity; because the former must always be the pattern of their +conduct in every state, and progress towards it is already possible +and necessary in this life; while the latter, under the name of +happiness, cannot be attained at all in this world (so far as our +own power is concerned), and therefore is made simply an object of +hope. Nevertheless, the Christian principle of morality itself is +not theological (so as to be heteronomy), but is autonomy of pure +practical reason, since it does not make the knowledge of God and +His will the foundation of these laws, but only of the attainment of +the summum bonum, on condition of following these laws, and it does +not even place the proper spring of this obedience in the desired +results, but solely in the conception of duty, as that of which the +faithful observance alone constitutes the worthiness to obtain those +happy consequences. + + + +* It is commonly held that the Christian precept of morality has no +advantage in respect of purity over the moral conceptions of the +Stoics; the distinction between them is, however, very obvious. The +Stoic system made the consciousness of strength of mind the pivot on +which all moral dispositions should turn; and although its disciples +spoke of duties and even defined them very well, yet they placed the +spring and proper determining principle of the will in an elevation of +the mind above the lower springs of the senses, which owe their +power only to weakness of mind. With them therefore, virtue was a sort +of heroism in the wise man raising himself above the animal nature +of man, is sufficient for Himself, and, while he prescribes duties +to others, is himself raised above them, and is not subject to any +temptation to transgress the moral law. All this, however, they +could not have done if they had conceived this law in all its purity +and strictness, as the precept of the Gospel does. When I give the +name idea to a perfection to which nothing adequate can be given in +experience, it does not follow that the moral ideas are thing +transcendent, that is something of which we could not even determine +the concept adequately, or of which it is uncertain whether there is +any object corresponding to it at all, as is the case with the ideas +of speculative reason; on the contrary, being types of practical +perfection, they serve as the indispensable rule of conduct and +likewise as the standard of comparison. Now if I consider Christian +morals on their philosophical side, then compared with the ideas of +the Greek schools, they would appear as follows: the ideas of the +Cynics, the Epicureans, the Stoics, and the Christians are: simplicity +of nature, prudence, wisdom, and holiness. In respect of the way of +attaining them, the Greek schools were distinguished from one +another thus that the Cynics only required common sense, the others +the path of science, but both found the mere use of natural powers +sufficient for the purpose. Christian morality, because its precept is +framed (as a moral precept must be) so pure and unyielding, takes from +man all confidence that he can be fully adequate to it, at least in +this life, but again sets it up by enabling us to hope that if we +act as well as it is in our power to do, then what is not in our power +will come in to our aid from another source, whether we know how +this may be or not. Aristotle and Plato differed only as to the origin +of our moral conceptions. + + + + {BOOK_2|CHAPTER_2 ^paragraph 50} + +In this manner, the moral laws lead through the conception of the +summum bonum as the object and final end of pure practical reason to +religion, that is, to the recognition of all duties as divine +commands, not as sanctions, that is to say, arbitrary ordinances of +a foreign and contingent in themselves, but as essential laws of every +free will in itself, which, nevertheless, must be regarded as commands +of the Supreme Being, because it is only from a morally perfect +(holy and good) and at the same time all-powerful will, and +consequently only through harmony with this will, that we can hope +to attain the summum bonum which the moral law makes it our duty to +take as the object of our endeavours. Here again, then, all remains +disinterested and founded merely on duty; neither fear nor hope +being made the fundamental springs, which if taken as principles would +destroy the whole moral worth of actions. The moral law commands me to +make the highest possible good in a world the ultimate object of all +my conduct. But I cannot hope to effect this otherwise than by the +harmony of my will with that of a holy and good Author of the world; +and although the conception of the summum bonum as a whole, in which +the greatest happiness is conceived as combined in the most exact +proportion with the highest degree of moral perfection (possible in +creatures), includes my own happiness, yet it is not this that is +the determining principle of the will which is enjoined to promote the +summum bonum, but the moral law, which, on the contrary, limits by +strict conditions my unbounded desire of happiness. + +Hence also morality is not properly the doctrine how we should +make ourselves happy, but how we should become worthy of happiness. It +is only when religion is added that there also comes in the hope of +participating some day in happiness in proportion as we have +endeavoured to be not unworthy of it. + +A man is worthy to possess a thing or a state when his possession of +it is in harmony with the summum bonum. We can now easily see that all +worthiness depends on moral conduct, since in the conception of the +summum bonum this constitutes the condition of the rest (which belongs +to one's state), namely, the participation of happiness. Now it +follows from this that morality should never be treated as a +doctrine of happiness, that is, an instruction how to become happy; +for it has to do simply with the rational condition (conditio sine qua +non) of happiness, not with the means of attaining it. But when +morality has been completely expounded (which merely imposes duties +instead of providing rules for selfish desires), then first, after the +moral desire to promote the summum bonum (to bring the kingdom of +God to us) has been awakened, a desire founded on a law, and which +could not previously arise in any selfish mind, and when for the +behoof of this desire the step to religion has been taken, then this +ethical doctrine may be also called a doctrine of happiness because +the hope of happiness first begins with religion only. + +We can also see from this that, when we ask what is God's ultimate +end in creating the world, we must not name the happiness of the +rational beings in it, but the summum bonum, which adds a further +condition to that wish of such beings, namely, the condition of +being worthy of happiness, that is, the morality of these same +rational beings, a condition which alone contains the rule by which +only they can hope to share in the former at the hand of a wise +Author. For as wisdom, theoretically considered, signifies the +knowledge of the summum bonum and, practically, the accordance of +the will with the summum bonum, we cannot attribute to a supreme +independent wisdom an end based merely on goodness. For we cannot +conceive the action of this goodness (in respect of the happiness of +rational beings) as suitable to the highest original good, except +under the restrictive conditions of harmony with the holiness * of +his will. Therefore, those who placed the end of creation in the glory +of God (provided that this is not conceived anthropomorphically as a +desire to be praised) have perhaps hit upon the best expression. For +nothing glorifies God more than that which is the most estimable thing +in the world, respect for his command, the observance of the holy duty +that his law imposes on us, when there is added thereto his glorious +plan of crowning such a beautiful order of things with corresponding +happiness. If the latter (to speak humanly) makes Him worthy of +love, by the former He is an object of adoration. Even men can never +acquire respect by benevolence alone, though they may gain love, so +that the greatest beneficence only procures them honour when it is +regulated by worthiness. + + + + {BOOK_2|CHAPTER_2 ^paragraph 55} + +* In order to make these characteristics of these conceptions +clear, I add the remark that whilst we ascribe to God various +attributes, the quality of which we also find applicable to creatures, +only that in Him they are raised to the highest degree, e.g., power, +knowledge, presence, goodness, etc., under the designations of +omnipotence, omniscience, omnipresence, etc., there are three that are +ascribed to God exclusively, and yet without the addition of +greatness, and which are all moral He is the only holy, the only +blessed, the only wise, because these conceptions already imply the +absence of limitation. In the order of these attributes He is also the +holy lawgiver (and creator), the good governor (and preserver) and the +just judge, three attributes which include everything by which God +is the object of religion, and in conformity with which the +metaphysical perfections are added of themselves in the reason. + + + +That in the order of ends, man (and with him every rational being) +is an end in himself, that is, that he can never be used merely as a +means by any (not even by God) without being at the same time an end +also himself, that therefore humanity in our person must be holy to +ourselves, this follows now of itself because he is the subject of the +moral law, in other words, of that which is holy in itself, and on +account of which and in agreement with which alone can anything be +termed holy. For this moral law is founded on the autonomy of his +will, as a free will which by its universal laws must necessarily be +able to agree with that to which it is to submit itself. + + + + VI. Of the Postulates of Pure Practical Reason Generally. + + {BOOK_2|CHAPTER_2 ^paragraph 60} + + + +They all proceed from the principle of morality, which is not a +postulate but a law, by which reason determines the will directly, +which will, because it is so determined as a pure will, requires these +necessary conditions of obedience to its precept. These postulates are +not theoretical dogmas but, suppositions practically necessary; +while then they do [not] extend our speculative knowledge, they give +objective reality to the ideas of speculative reason in general (by +means of their reference to what is practical), and give it a right to +concepts, the possibility even of which it could not otherwise venture +to affirm. + +These postulates are those of immortality, freedom positively +considered (as the causality of a being so far as he belongs to the +intelligible world), and the existence of God. The first results +from the practically necessary condition of a duration adequate to the +complete fulfilment of the moral law; the second from the necessary +supposition of independence of the sensible world, and of the +faculty of determining one's will according to the law of an +intelligible world, that is, of freedom; the third from the +necessary condition of the existence of the summum bonum in such an +intelligible world, by the supposition of the supreme independent +good, that is, the existence of God. + +Thus the fact that respect for the moral law necessarily makes the +summum bonum an object of our endeavours, and the supposition thence +resulting of its objective reality, lead through the postulates of +practical reason to conceptions which speculative reason might +indeed present as problems, but could never solve. Thus it leads: 1. +To that one in the solution of which the latter could do nothing but +commit paralogisms (namely, that of immortality), because it could not +lay hold of the character of permanence, by which to complete the +psychological conception of an ultimate subject necessarily ascribed +to the soul in self-consciousness, so as to make it the real +conception of a substance, a character which practical reason +furnishes by the postulate of a duration required for accordance +with the moral law in the summum bonum, which is the whole end of +practical reason. 2. It leads to that of which speculative reason +contained nothing but antinomy, the solution of which it could only +found on a notion problematically conceivable indeed, but whose +objective reality it could not prove or determine, namely, the +cosmological idea of an intelligible world and the consciousness of +our existence in it, by means of the postulate of freedom (the reality +of which it lays down by virtue of the moral law), and with it +likewise the law of an intelligible world, to which speculative reason +could only point, but could not define its conception. 3. What +speculative reason was able to think, but was obliged to leave +undetermined as a mere transcendental ideal, viz., the theological +conception of the first Being, to this it gives significance (in a +practical view, that is, as a condition of the possibility of the +object of a will determined by that law), namely, as the supreme +principle of the summum bonum in an intelligible world, by means of +moral legislation in it invested with sovereign power. + +Is our knowledge, however, actually extended in this way by pure +practical reason, and is that immanent in practical reason which for +the speculative was only transcendent? Certainly, but only in a +practical point of view. For we do not thereby take knowledge of the +nature of our souls, nor of the intelligible world, nor of the Supreme +Being, with respect to what they are in themselves, but we have merely +combined the conceptions of them in the practical concept of the +summum bonum as the object of our will, and this altogether a +priori, but only by means of the moral law, and merely in reference to +it, in respect of the object which it commands. But how freedom is +possible, and how we are to conceive this kind of causality +theoretically and positively, is not thereby discovered; but only that +there is such a causality is postulated by the moral law and in its +behoof. It is the same with the remaining ideas, the possibility of +which no human intelligence will ever fathom, but the truth of +which, on the other hand, no sophistry will ever wrest from the +conviction even of the commonest man. + + {BOOK_2|CHAPTER_2 ^paragraph 65} + + + +VII. How is it possible to conceive an Extension of Pure + + Reason in a Practical point of view, without its + + Knowledge as Speculative being enlarged at + + the same time? + + {BOOK_2|CHAPTER_2 ^paragraph 70} + + + +In order not to be too abstract, we will answer this question at +once in its application to the present case. In order to extend a pure +cognition practically, there must be an a priori purpose given, that +is, an end as object (of the will), which independently of all +theological principle is presented as practically necessary by an +imperative which determines the will directly (a categorical +imperative), and in this case that is the summum bonum. This, however, +is not possible without presupposing three theoretical conceptions +(for which, because they are mere conceptions of pure reason, no +corresponding intuition can be found, nor consequently by the path +of theory any objective reality); namely, freedom, immortality, and +God. Thus by the practical law which commands the existence of the +highest good possible in a world, the possibility of those objects +of pure speculative reason is postulated, and the objective reality +which the latter could not assure them. By this the theoretical +knowledge of pure reason does indeed obtain an accession; but it +consists only in this, that those concepts which otherwise it had to +look upon as problematical (merely thinkable) concepts, are now +shown assertorially to be such as actually have objects; because +practical reason indispensably requires their existence for the +possibility of its object, the summum bonum, which practically is +absolutely necessary, and this justifies theoretical reason in +assuming them. But this extension of theoretical reason is no +extension of speculative, that is, we cannot make any positive use +of it in a theoretical point of view. For as nothing is accomplished +in this by practical reason, further than that these concepts are real +and actually have their (possible) objects, and nothing in the way +of intuition of them is given thereby (which indeed could not be +demanded), hence the admission of this reality does not render any +synthetical proposition possible. Consequently, this discovery does +not in the least help us to extend this knowledge of ours in a +speculative point of view, although it does in respect of the +practical employment of pure reason. The above three ideas of +speculative reason are still in themselves not cognitions; they are +however (transcendent) thoughts, in which there is nothing impossible. +Now, by help of an apodeictic practical law, being necessary +conditions of that which it commands to be made an object, they +acquire objective reality; that is, we learn from it that they have +objects, without being able to point out how the conception of them is +related to an object, and this, too, is still not a cognition of these +objects; for we cannot thereby form any synthetical judgement about +them, nor determine their application theoretically; consequently, +we can make no theoretical rational use of them at all, in which use +all speculative knowledge of reason consists. Nevertheless, the +theoretical knowledge, not indeed of these objects, but of reason +generally, is so far enlarged by this, that by the practical +postulates objects were given to those ideas, a merely problematical +thought having by this means first acquired objective reality. There +is therefore no extension of the knowledge of given supersensible +objects, but an extension of theoretical reason and of its knowledge +in respect of the supersensible generally; inasmuch as it is compelled +to admit that there are such objects, although it is not able to +define them more closely, so as itself to extend this knowledge of the +objects (which have now been given it on practical grounds, and only +for practical use). For this accession, then, pure theoretical reason, +for which all those ideas are transcendent and without object, has +simply to thank its practical faculty. In this they become immanent +and constitutive, being the source of the possibility of realizing the +necessary object of pure practical reason (the summum bonum); +whereas apart from this they are transcendent, and merely regulative +principles of speculative reason, which do not require it to assume +a new object beyond experience, but only to bring its use in +experience nearer to completeness. But when once reason is in +possession of this accession, it will go to work with these ideas as +speculative reason (properly only to assure the certainty of its +practical use) in a negative manner: that is, not extending but +clearing up its knowledge so as on one side to keep off +anthropomorphism, as the source of superstition, or seeming +extension of these conceptions by supposed experience; and on the +other side fanaticism, which promises the same by means of +supersensible intuition or feelings of the like kind. All these are +hindrances to the practical use of pure reason, so that the removal of +them may certainly be considered an extension of our knowledge in a +practical point of view, without contradicting the admission that +for speculative purposes reason has not in the least gained by this. + +Every employment of reason in respect of an object requires pure +concepts of the understanding (categories), without which no object +can be conceived. These can be applied to the theoretical employment +of reason, i.e., to that kind of knowledge, only in case an +intuition (which is always sensible) is taken as a basis, and +therefore merely in order to conceive by means of- them an object of +possible experience. Now here what have to be thought by means of +the categories in order to be known are ideas of reason, which +cannot be given in any experience. Only we are not here concerned with +the theoretical knowledge of the objects of these ideas, but only with +this, whether they have objects at all. This reality is supplied by +pure practical reason, and theoretical reason has nothing further to +do in this but to think those objects by means of categories. This, as +we have elsewhere clearly shown, can be done well enough without +needing any intuition (either sensible or supersensible) because the +categories have their seat and origin in the pure understanding, +simply as the faculty of thought, before and independently of any +intuition, and they always only signify an object in general, no +matter in what way it may be given to us. Now when the categories +are to be applied to these ideas, it is not possible to give them +any object in intuition; but that such an object actually exists, +and consequently that the category as a mere form of thought is here +not empty but has significance, this is sufficiently assured them by +an object which practical reason presents beyond doubt in the +concept of the summum bonum, the reality of the conceptions which +are required for the possibility of the summum bonum; without, +however, effecting by this accession the least extension of our +knowledge on theoretical principles. + + + +When these ideas of God, of an intelligible world (the kingdom of +God), and of immortality are further determined by predicates taken +from our own nature, we must not regard this determination as a +sensualizing of those pure rational ideas (anthropomorphism), nor as a +transcendent knowledge of supersensible objects; for these +predicates are no others than understanding and will, considered too +in the relation to each other in which they must be conceived in the +moral law, and therefore, only so far as a pure practical use is +made of them. As to all the rest that belongs to these conceptions +psychologically, that is, so far as we observe these faculties of ours +empirically in their exercise (e.g., that the understanding of man +is discursive, and its notions therefore not intuitions but +thoughts, that these follow one another in time, that his will has its +satisfaction always dependent on the existence of its object, etc., +which cannot be the case in the Supreme Being), from all this we +abstract in that case, and then there remains of the notions by +which we conceive a pure intelligence nothing more than just what is +required for the possibility of conceiving a moral law. There is +then a knowledge of God indeed, but only for practical purposes, +and, if we attempt to extend it to a theoretical knowledge, we find an +understanding that has intuitions, not thoughts, a will that is +directed to objects on the existence of which its satisfaction does +not in the least depend (not to mention the transcendental predicates, +as, for example, a magnitude of existence, that is duration, which, +however, is not in time, the only possible means we have of conceiving +existence as magnitude). Now these are all attributes of which we +can form no conception that would help to the knowledge of the object, +and we learn from this that they can never be used for a theory of +supersensible beings, so that on this side they are quite incapable of +being the foundation of a speculative knowledge, and their use is +limited simply to the practice of the moral law. + + {BOOK_2|CHAPTER_2 ^paragraph 75} + +This last is so obvious, and can be proved so clearly by fact, +that we may confidently challenge all pretended natural theologians (a +singular name) * to specify (over and above the merely ontological +predicates) one single attribute, whether of the understanding or of +the will, determining this object of theirs, of which we could not +show incontrovertibly that, if we abstract from it everything +anthropomorphic, nothing would remain to us but the mere word, without +our being able to connect with it the smallest notion by which we +could hope for an extension of theoretical knowledge. But as to the +practical, there still remains to us of the attributes of +understanding and will the conception of a relation to which objective +reality is given by the practical law (which determines a priori +precisely this relation of the understanding to the will). When once +this is done, then reality is given to the conception of the object of +a will morally determined (the conception of the summum bonum), and +with it to the conditions of its possibility, the ideas of God, +freedom, and immortality, but always only relatively to the practice +of the moral law (and not for any speculative purpose). + + + +* Learning is properly only the whole content of the historical +sciences. Consequently it is only the teacher of revealed theology +that can be called a learned theologian. If, however, we choose to +call a man learned who is in possession of the rational sciences +(mathematics and philosophy), although even this would be contrary +to the signification of the word (which always counts as learning only +that which one must be "learned" and which, therefore, he cannot +discover of himself by reason), even in that case the philosopher +would make too poor a figure with his knowledge of God as a positive +science to let himself be called on that account a learned man. + + + +According to these remarks it is now easy to find the answer to +the weighty question whether the notion of God is one belonging to +physics (and therefore also to metaphysics, which contains the pure +a priori principles of the former in their universal import) or to +morals. If we have recourse to God as the Author of all things, in +order to explain the arrangements of nature or its changes, this is at +least not a physical explanation, and is a complete confession that +our philosophy has come to an end, since we are obliged to assume +something of which in itself we have otherwise no conception, in order +to be able to frame a conception of the possibility of what we see +before our eyes. Metaphysics, however, cannot enable us to attain by +certain inference from the knowledge of this world to the conception +of God and to the proof of His existence, for this reason, that in +order to say that this world could be produced only by a God +(according to the conception implied by this word) we should know this +world as the most perfect whole possible; and for this purpose +should also know all possible worlds (in order to be able to compare +them with this); in other words, we should be omniscient. It is +absolutely impossible, however, to know the existence of this Being +from mere concepts, because every existential proposition, that is, +every proposition that affirms the existence of a being of which I +frame a concept, is a synthetic proposition, that is, one by which I +go beyond that conception and affirm of it more than was thought in +the conception itself; namely, that this concept in the +understanding has an object corresponding to it outside the +understanding, and this it is obviously impossible to elicit by any +reasoning. There remains, therefore, only one single process +possible for reason to attain this knowledge, namely, to start from +the supreme principle of its pure practical use (which in every case +is directed simply to the existence of something as a consequence of +reason) and thus determine its object. Then its inevitable problem, +namely, the necessary direction of the will to the summum bonum, +discovers to us not only the necessity of assuming such a First +Being in reference to the possibility of this good in the world, +but, what is most remarkable, something which reason in its progress +on the path of physical nature altogether failed to find, namely, an +accurately defined conception of this First Being. As we can know only +a small part of this world, and can still less compare it with all +possible worlds, we may indeed from its order, design, and +greatness, infer a wise, good, powerful, etc., Author of it, but not +that He is all-wise, all-good, all-powerful, etc. It may indeed very +well be granted that we should be justified in supplying this +inevitable defect by a legitimate and reasonable hypothesis; namely, +that when wisdom, goodness, etc, are displayed in all the parts that +offer themselves to our nearer knowledge, it is just the same in all +the rest, and that it would therefore be reasonable to ascribe all +possible perfections to the Author of the world, but these are not +strict logical inferences in which we can pride ourselves on our +insight, but only permitted conclusions in which we may be indulged +and which require further recommendation before we can make use of +them. On the path of empirical inquiry then (physics), the +conception of God remains always a conception of the perfection of the +First Being not accurately enough determined to be held adequate to +the conception of Deity. (With metaphysic in its transcendental part +nothing whatever can be accomplished.) + + {BOOK_2|CHAPTER_2 ^paragraph 80} + +When I now try to test this conception by reference to the object of +practical reason, I find that the moral principle admits as possible +only the conception of an Author of the world possessed of the highest +perfection. He must be omniscient, in order to know my conduct up to +the inmost root of my mental state in all possible cases and into +all future time; omnipotent, in order to allot to it its fitting +consequences; similarly He must be omnipresent, eternal, etc. Thus the +moral law, by means of the conception of the summum bonum as the +object of a pure practical reason, determines the concept of the First +Being as the Supreme Being; a thing which the physical (and in its +higher development the metaphysical), in other words, the whole +speculative course of reason, was unable to effect. The conception +of God, then, is one that belongs originally not to physics, i.e., +to speculative reason, but to morals. The same may be said of the +other conceptions of reason of which we have treated above as +postulates of it in its practical use. + +In the history of Grecian philosophy we find no distinct traces of a +pure rational theology earlier than Anaxagoras; but this is not +because the older philosophers had not intelligence or penetration +enough to raise themselves to it by the path of speculation, at +least with the aid of a thoroughly reasonable hypothesis. What could +have been easier, what more natural, than the thought which of +itself occurs to everyone, to assume instead of several causes of +the world, instead of an indeterminate degree of perfection, a +single rational cause having all perfection? But the evils in the +world seemed to them to be much too serious objections to allow them +to feel themselves justified in such a hypothesis. They showed +intelligence and penetration then in this very point, that they did +not allow themselves to adopt it, but on the contrary looked about +amongst natural causes to see if they could not find in them the +qualities and power required for a First Being. But when this acute +people had advanced so far in their investigations of nature as to +treat even moral questions philosophically, on which other nations had +never done anything but talk, then first they found a new and +practical want, which did not fail to give definiteness to their +conception of the First Being: and in this the speculative reason +played the part of spectator, or at best had the merit of embellishing +a conception that had not grown on its own ground, and of applying a +series of confirmations from the study of nature now brought forward +for the first time, not indeed to strengthen the authority of this +conception (which was already established), but rather to make a +show with a supposed discovery of theoretical reason. + + + +From these remarks, the reader of the Critique of Pure Speculative +Reason will be thoroughly convinced how highly necessary that +laborious deduction of the categories was, and how fruitful for +theology and morals. For if, on the one hand, we place them in pure +understanding, it is by this deduction alone that we can be +prevented from regarding them, with Plato, as innate, and founding +on them extravagant pretensions to theories of the supersensible, to +which we can see no end, and by which we should make theology a +magic lantern of chimeras; on the other hand, if we regard them as +acquired, this deduction saves us from restricting, with Epicurus, all +and every use of them, even for practical purposes, to the objects and +motives of the senses. But now that the Critique has shown by that +deduction, first, that they are not of empirical origin, but have +their seat and source a priori in the pure understanding; secondly, +that as they refer to objects in general independently of the +intuition of them, hence, although they cannot effect theoretical +knowledge, except in application to empirical objects, yet when +applied to an object given by pure practical reason they enable us +to conceive the supersensible definitely, only so far, however, as +it is defined by such predicates as are necessarily connected with the +pure practical purpose given a priori and with its possibility. The +speculative restriction of pure reason and its practical extension +bring it into that relation of equality in which reason in general can +be employed suitably to its end, and this example proves better than +any other that the path to wisdom, if it is to be made sure and not to +be impassable or misleading, must with us men inevitably pass +through science; but it is not till this is complete that we can be +convinced that it leads to this goal. + + + + {BOOK_2|CHAPTER_2 ^paragraph 85} + + VIII. Of Belief from a Requirement of Pure Reason. + + + +A want or requirement of pure reason in its speculative use leads +only to a hypothesis; that of pure practical reason to a postulate; +for in the former case I ascend from the result as high as I please in +the series of causes, not in order to give objective reality to the +result (e.g., the causal connection of things and changes in the +world), but in order thoroughly to satisfy my inquiring reason in +respect of it. Thus I see before me order and design in nature, and +need not resort to speculation to assure myself of their reality, +but to explain them I have to presuppose a Deity as their cause; and +then since the inference from an effect to a definite cause is +always uncertain and doubtful, especially to a cause so precise and so +perfectly defined as we have to conceive in God, hence the highest +degree of certainty to which this pre-supposition can be brought is +that it is the most rational opinion for us men. * On the other hand, +a requirement of pure practical reason is based on a duty, that of +making something (the summum bonum) the object of my will so as to +promote it with all my powers; in which case I must suppose its +possibility and, consequently, also the conditions necessary +thereto, namely, God, freedom, and immortality; since I cannot prove +these by my speculative reason, although neither can I refute them. +This duty is founded on something that is indeed quite independent +of these suppositions and is of itself apodeictically certain, namely, +the moral law; and so far it needs no further support by theoretical +views as to the inner constitution of things, the secret final aim +of the order of the world, or a presiding ruler thereof, in order to +bind me in the most perfect manner to act in unconditional +conformity to the law. But the subjective effect of this law, +namely, the mental disposition conformed to it and made necessary by +it, to promote the practically possible summum bonum, this +pre-supposes at least that the latter is possible, for it would be +practically impossible to strive after the object of a conception +which at bottom was empty and had no object. Now the above-mentioned +postulates concern only the physical or metaphysical conditions of the +possibility of the summum bonum; in a word, those which lie in the +nature of things; not, however, for the sake of an arbitrary +speculative purpose, but of a practically necessary end of a pure +rational will, which in this case does not choose, but obeys an +inexorable command of reason, the foundation of which is objective, in +the constitution of things as they must be universally judged by +pure reason, and is not based on inclination; for we are in nowise +justified in assuming, on account of what we wish on merely subjective +grounds, that the means thereto are possible or that its object is +real. This, then, is an absolutely necessary requirement, and what +it pre-supposes is not merely justified as an allowable hypothesis, +but as a postulate in a practical point of view; and admitting that +the pure moral law inexorably binds every man as a command (not as a +rule of prudence), the righteous man may say: "I will that there be +a God, that my existence in this world be also an existence outside +the chain of physical causes and in a pure world of the understanding, +and lastly, that my duration be endless; I firmly abide by this, and +will not let this faith be taken from me; for in this instance alone +my interest, because I must not relax anything of it, inevitably +determines my judgement, without regarding sophistries, however unable +I may be to answer them or to oppose them with others more +plausible. *(2) + + + +* But even here we should not be able to allege a requirement of +reason, if we had not before our eyes a problematical, but yet +inevitable, conception of reason, namely, that of an absolutely +necessary being. This conception now seeks to be defined, and this, in +addition to the tendency to extend itself, is the objective ground +of a requirement of speculative reason, namely, to have a more precise +definition of the conception of a necessary being which is to serve as +the first cause of other beings, so as to make these latter knowable +by some means. Without such antecedent necessary problems there are no +requirements- at least not of pure reason- the rest are requirements +of inclination. + + {BOOK_2|CHAPTER_2 ^paragraph 90} + +*(2) In the Deutsches Museum, February, 1787, there is a +dissertation by a very subtle and clear-headed man, the late +Wizenmann, whose early death is to be lamented, in which he disputes +the right to argue from a want to the objective reality of its object, +and illustrates the point by the example of a man in love, who +having fooled himself into an idea of beauty, which is merely a +chimera of his own brain, would fain conclude that such an object +really exists somewhere. I quite agree with him in this, in all +cases where the want is founded on inclination, which cannot +necessarily postulate the existence of its object even for the man +that is affected by it, much less can it contain a demand valid for +everyone, and therefore it is merely a subjective ground of the +wish. But in the present case we have a want of reason springing +from an objective determining principle of the will, namely, the moral +law, which necessarily binds every rational being, and therefore +justifies him in assuming a priori in nature the conditions proper for +it, and makes the latter inseparable from the complete practical use +of reason. It is a duty to realize the summum bonum to the utmost of +our power, therefore it must be possible, consequently it is +unavoidable for every rational being in the world to assume what is +necessary for its objective possibility. The assumption is as +necessary as the moral law, in connection with which alone it is +valid. + + + +In order to prevent misconception in the use of a notion as yet so +unusual as that of a faith of pure practical reason, let me be +permitted to add one more remark. It might almost seem as if this +rational faith were here announced as itself a command, namely, that +we should assume the summum bonum as possible. But a faith that is +commanded is nonsense. Let the preceding analysis, however, be +remembered of what is required to be supposed in the conception of the +summum bonum, and it will be seen that it cannot be commanded to +assume this possibility, and no practical disposition of mind is +required to admit it; but that speculative reason must concede it +without being asked, for no one can affirm that it is impossible in +itself that rational beings in the world should at the same time be +worthy of happiness in conformity with the moral law and also +possess this happiness proportionately. Now in respect of the first +element of the summum bonum, namely, that which concerns morality, the +moral law gives merely a command, and to doubt the possibility of that +element would be the same as to call in question the moral law itself. +But as regards the second element of that object, namely, happiness +perfectly proportioned to that worthiness, it is true that there is no +need of a command to admit its possibility in general, for theoretical +reason has nothing to say against it; but the manner in which we +have to conceive this harmony of the laws of nature with those of +freedom has in it something in respect of which we have a choice, +because theoretical reason decides nothing with apodeictic certainty +about it, and in respect of this there may be a moral interest which +turns the scale. + +I had said above that in a mere course of nature in the world an +accurate correspondence between happiness and moral worth is not to be +expected and must be regarded as impossible, and that therefore the +possibility of the summum bonum cannot be admitted from this side +except on the supposition of a moral Author of the world. I +purposely reserved the restriction of this judgement to the subjective +conditions of our reason, in order not to make use of it until the +manner of this belief should be defined more precisely. The fact is +that the impossibility referred to is merely subjective, that is, +our reason finds it impossible for it to render conceivable in the way +of a mere course of nature a connection so exactly proportioned and so +thoroughly adapted to an end, between two sets of events happening +according to such distinct laws; although, as with everything else +in nature that is adapted to an end, it cannot prove, that is, show by +sufficient objective reason, that it is not possible by universal laws +of nature. + +Now, however, a deciding principle of a different kind comes into +play to turn the scale in this uncertainty of speculative reason. +The command to promote the summum bonum is established on an objective +basis (in practical reason); the possibility of the same in general is +likewise established on an objective basis (in theoretical reason, +which has nothing to say against it). But reason cannot decide +objectively in what way we are to conceive this possibility; whether +by universal laws of nature without a wise Author presiding over +nature, or only on supposition of such an Author. Now here there comes +in a subjective condition of reason, the only way theoretically +possible for it, of conceiving the exact harmony of the kingdom of +nature with the kingdom of morals, which is the condition of the +possibility of the summum bonum; and at the same time the only one +conducive to morality (which depends on an objective law of reason). +Now since the promotion of this summum bonum, and therefore the +supposition of its possibility, are objectively necessary (though only +as a result of practical reason), while at the same time the manner in +which we would conceive it rests with our own choice, and in this +choice a free interest of pure practical reason decides for the +assumption of a wise Author of the world; it is clear that the +principle that herein determines our judgement, though as a want it is +subjective, yet at the same time being the means of promoting what +is objectively (practically) necessary, is the foundation of a maxim +of belief in a moral point of view, that is, a faith of pure practical +reason. This, then, is not commanded, but being a voluntary +determination of our judgement, conducive to the moral (commanded) +purpose, and moreover harmonizing with the theoretical requirement +of reason, to assume that existence and to make it the foundation of +our further employment of reason, it has itself sprung from the +moral disposition of mind; it may therefore at times waver even in the +well-disposed, but can never be reduced to unbelief. + + {BOOK_2|CHAPTER_2 ^paragraph 95} + + + + IX. Of the Wise Adaptation of Man's Cognitive Faculties + + to his Practical Destination. + + + +If human nature is destined to endeavour after the summum bonum, +we must suppose also that the measure of its cognitive faculties, +and particularly their relation to one another, is suitable to this +end. Now the Critique of Pure Speculative Reason proves that this is +incapable of solving satisfactorily the most weighty problems that are +proposed to it, although it does not ignore the natural and +important hints received from the same reason, nor the great steps +that it can make to approach to this great goal that is set before it, +which, however, it can never reach of itself, even with the help of +the greatest knowledge of nature. Nature then seems here to have +provided us only in a step-motherly fashion with the faculty required +for our end. + + {BOOK_2|CHAPTER_2 ^paragraph 100} + +Suppose, now, that in this matter nature had conformed to our wish +and had given us that capacity of discernment or that enlightenment +which we would gladly possess, or which some imagine they actually +possess, what would in all probability be the consequence? Unless +our whole nature were at the same time changed, our inclinations, +which always have the first word, would first of all demand their +own satisfaction, and, joined with rational reflection, the greatest +possible and most lasting satisfaction, under the name of happiness; +the moral law would afterwards speak, in order to keep them within +their proper bounds, and even to subject them all to a higher end, +which has no regard to inclination. But instead of the conflict that +the moral disposition has now to carry on with the inclinations, in +which, though after some defeats, moral strength of mind may be +gradually acquired, God and eternity with their awful majesty would +stand unceasingly before our eyes (for what we can prove perfectly +is to us as certain as that of which we are assured by the sight of +our eyes). Transgression of the law, would, no doubt, be avoided; what +is commanded would be done; but the mental disposition, from which +actions ought to proceed, cannot be infused by any command, and in +this case the spur of action is ever active and external, so that +reason has no need to exert itself in order to gather strength to +resist the inclinations by a lively representation of the dignity of +the law: hence most of the actions that conformed to the law would +be done from fear, a few only from hope, and none at all from duty, +and the moral worth of actions, on which alone in the eyes of +supreme wisdom the worth of the person and even that of the world +depends, would cease to exist. As long as the nature of man remains +what it is, his conduct would thus be changed into mere mechanism, +in which, as in a puppet-show, everything would gesticulate well, +but there would be no life in the figures. Now, when it is quite +otherwise with us, when with all the effort of our reason we have only +a very obscure and doubtful view into the future, when the Governor of +the world allows us only to conjecture his existence and his +majesty, not to behold them or prove them clearly; and on the other +hand, the moral law within us, without promising or threatening +anything with certainty, demands of us disinterested respect; and only +when this respect has become active and dominant, does it allow us +by means of it a prospect into the world of the supersensible, and +then only with weak glances: all this being so, there is room for true +moral disposition, immediately devoted to the law, and a rational +creature can become worthy of sharing in the summum bonum that +corresponds to the worth of his person and not merely to his +actions. Thus what the study of nature and of man teaches us +sufficiently elsewhere may well be true here also; that the +unsearchable wisdom by which we exist is not less worthy of admiration +in what it has denied than in what it has granted. + +PART_2|METHODOLOGY + + SECOND PART. + + + + Methodology of Pure Practical Reason. + + + +By the methodology of pure practical reason we are not to understand +the mode of proceeding with pure practical principles (whether in +study or in exposition), with a view to a scientific knowledge of +them, which alone is what is properly called method elsewhere in +theoretical philosophy (for popular knowledge requires a manner, +science a method, i.e., a process according to principles of reason by +which alone the manifold of any branch of knowledge can become a +system). On the contrary, by this methodology is understood the mode +in which we can give the laws of pure practical reason access to the +human mind and influence on its maxims, that is, by which we can +make the objectively practical reason subjectively practical also. + +Now it is clear enough that those determining principles of the will +which alone make maxims properly moral and give them a moral worth, +namely, the direct conception of the law and the objective necessity +of obeying it as our duty, must be regarded as the proper springs of +actions, since otherwise legality of actions might be produced, but +not morality of character. But it is not so clear; on the contrary, it +must at first sight seem to every one very improbable that even +subjectively that exhibition of pure virtue can have more power over +the human mind, and supply a far stronger spring even for effecting +that legality of actions, and can produce more powerful resolutions to +prefer the law, from pure respect for it, to every other +consideration, than all the deceptive allurements of pleasure or of +all that may be reckoned as happiness, or even than all threatenings +of pain and misfortune. Nevertheless, this is actually the case, and +if human nature were not so constituted, no mode of presenting the law +by roundabout ways and indirect recommendations would ever produce +morality of character. All would be simple hypocrisy; the law would be +hated, or at least despised, while it was followed for the sake of +one's own advantage. The letter of the law (legality) would be found +in our actions, but not the spirit of it in our minds (morality); +and as with all our efforts we could not quite free ourselves from +reason in our judgement, we must inevitably appear in our own eyes +worthless, depraved men, even though we should seek to compensate +ourselves for this mortification before the inner tribunal, by +enjoying the pleasure that a supposed natural or divine law might be +imagined to have connected with it a sort of police machinery, +regulating its operations by what was done without troubling itself +about the motives for doing it. + +It cannot indeed be denied that in order to bring an uncultivated or +degraded mind into the track of moral goodness some preparatory +guidance is necessary, to attract it by a view of its own advantage, +or to alarm it by fear of loss; but as soon as this mechanical work, +these leading-strings have produced some effect, then we must bring +before the mind the pure moral motive, which, not only because it is +the only one that can be the foundation of a character (a +practically consistent habit of mind with unchangeable maxims), but +also because it teaches a man to feel his own dignity, gives the +mind a power unexpected even by himself, to tear himself from all +sensible attachments so far as they would fain have the rule, and to +find a rich compensation for the sacrifice he offers, in the +independence of his rational nature and the greatness of soul to which +he sees that he is destined. We will therefore show, by such +observations as every one can make, that this property of our minds, +this receptivity for a pure moral interest, and consequently the +moving force of the pure conception of virtue, when it is properly +applied to the human heart, is the most powerful spring and, when a +continued and punctual observance of moral maxims is in question, +the only spring of good conduct. It must, however, be remembered +that if these observations only prove the reality of such a feeling, +but do not show any moral improvement brought about by it, this is +no argument against the only method that exists of making the +objectively practical laws of pure reason subjectively practical, +through the mere force of the conception of duty; nor does it prove +that this method is a vain delusion. For as it has never yet come into +vogue, experience can say nothing of its results; one can only ask for +proofs of the receptivity for such springs, and these I will now +briefly present, and then sketch the method of founding and +cultivating genuine moral dispositions. + + {PART_2|METHODOLOGY ^paragraph 5} + +When we attend to the course of conversation in mixed companies, +consisting not merely of learned persons and subtle reasoners, but +also of men of business or of women, we observe that, besides +story-telling and jesting, another kind of entertainment finds a place +in them, namely, argument; for stories, if they are to have novelty +and interest, are soon exhausted, and jesting is likely to become +insipid. Now of all argument there is none in which persons are more +ready to join who find any other subtle discussion tedious, none +that brings more liveliness into the company, than that which concerns +the moral worth of this or that action by which the character of +some person is to be made out. Persons, to whom in other cases +anything subtle and speculative in theoretical questions is dry and +irksome, presently join in when the question is to make out the +moral import of a good or bad action that has been related, and they +display an exactness, a refinement, a subtlety, in excogitating +everything that can lessen the purity of purpose, and consequently the +degree of virtue in it, which we do not expect from them in any +other kind of speculation. In these criticisms, persons who are +passing judgement on others often reveal their own character: some, in +exercising their judicial office, especially upon the dead, seem +inclined chiefly to defend the goodness that is related of this or +that deed against all injurious charges of insincerity, and ultimately +to defend the whole moral worth of the person against the reproach +of dissimulation and secret wickedness; others, on the contrary, +turn their thoughts more upon attacking this worth by accusation and +fault finding. We cannot always, however, attribute to these latter +the intention of arguing away virtue altogether out of all human +examples in order to make it an empty name; often, on the contrary, it +is only well-meant strictness in determining the true moral import +of actions according to an uncompromising law. Comparison with such +a law, instead of with examples, lowers self-conceit in moral +matters very much, and not merely teaches humility, but makes every +one feel it when he examines himself closely. Nevertheless, we can for +the most part observe, in those who defend the purity of purpose in +giving examples that where there is the presumption of uprightness +they are anxious to remove even the least spot, lest, if all +examples had their truthfulness disputed, and if the purity of all +human virtue were denied, it might in the end be regarded as a mere +phantom, and so all effort to attain it be made light of as vain +affectation and delusive conceit. + +I do not know why the educators of youth have not long since made +use of this propensity of reason to enter with pleasure upon the +most subtle examination of the practical questions that are thrown up; +and why they have not, after first laying the foundation of a purely +moral catechism, searched through the biographies of ancient and +modern times with the view of having at hand instances of the duties +laid down, in which, especially by comparison of similar actions under +different circumstances, they might exercise the critical judgement of +their scholars in remarking their greater or less moral +significance. This is a thing in which they would find that even early +youth, which is still unripe for speculation of other kinds, would +soon Become very acute and not a little interested, because it feels +the progress of its faculty of judgement; and, what is most important, +they could hope with confidence that the frequent practice of +knowing and approving good conduct in all its purity, and on the other +hand of remarking with regret or contempt the least deviation from it, +although it may be pursued only as a sport in which children may +compete with one another, yet will leave a lasting impression of +esteem on the one hand and disgust on the other; and so, by the mere +habit of looking on such actions as deserving approval or blame, a +good foundation would be laid for uprightness in the future course +of life. Only I wish they would spare them the example of so-called +noble (super-meritorious) actions, in which our sentimental books so +much abound, and would refer all to duty merely, and to the worth that +a man can and must give himself in his own eyes by the consciousness +of not having transgressed it, since whatever runs up into empty +wishes and longings after inaccessible perfection produces mere heroes +of romance, who, while they pique themselves on their feeling for +transcendent greatness, release themselves in return from the +observance of common and every-day obligations, which then seem to +them petty and insignificant. * + + + +* It is quite proper to extol actions that display a great, +unselfish, sympathizing mind or humanity. But, in this case, we must +fix attention not so much on the elevation of soul, which is very +fleeting and transitory, as on the subjection of the heart to duty, +from which a more enduring impression may be expected, because this +implies principle (whereas the former only implies ebullitions). One +need only reflect a little and he will always find a debt that he +has by some means incurred towards the human race (even if it were +only this, by the inequality of men in the civil constitution, +enjoys advantages on account of which others must be the more in +want), which will prevent the thought of duty from being repressed +by the self-complacent imagination of merit. + + + + {PART_2|METHODOLOGY ^paragraph 10} + +But if it is asked: "What, then, is really pure morality, by which +as a touchstone we must test the moral significance of every +action," then I must admit that it is only philosophers that can +make the decision of this question doubtful, for to common sense it +has been decided long ago, not indeed by abstract general formulae, +but by habitual use, like the distinction between the right and left +hand. We will then point out the criterion of pure virtue in an +example first, and, imagining that it is set before a boy, of say +ten years old, for his judgement, we will see whether he would +necessarily judge so of himself without being guided by his teacher. +Tell him the history of an honest man whom men want to persuade to +join the calumniators of an innocent and powerless person (say Anne +Boleyn, accused by Henry VIII of England). He is offered advantages, +great gifts, or high rank; he rejects them. This will excite mere +approbation and applause in the mind of the hearer. Now begins the +threatening of loss. Amongst these traducers are his best friends, who +now renounce his friendship; near kinsfolk, who threaten to disinherit +him (he being without fortune); powerful persons, who can persecute +and harass him in all places and circumstances; a prince, who +threatens him with loss of freedom, yea, loss of life. Then to fill +the measure of suffering, and that he may feel the pain that only +the morally good heart can feel very deeply, let us conceive his +family threatened with extreme distress and want, entreating him to +yield; conceive himself, though upright, yet with feelings not hard or +insensible either to compassion or to his own distress; conceive +him, I say, at the moment when he wishes that he had never lived to +see the day that exposed him to such unutterable anguish, yet +remaining true to his uprightness of purpose, without wavering or even +doubting; then will my youthful hearer be raised gradually from mere +approval to admiration, from that to amazement, and finally to the +greatest veneration, and a lively wish that he himself could be such a +man (though certainly not in such circumstances). Yet virtue is here +worth so much only because it costs so much, not because it brings any +profit. All the admiration, and even the endeavour to resemble this +character, rest wholly on the purity of the moral principle, which can +only be strikingly shown by removing from the springs of action +everything that men may regard as part of happiness. Morality, then, +must have the more power over the human heart the more purely it is +exhibited. Whence it follows that, if the law of morality and the +image of holiness and virtue are to exercise any influence at all on +our souls, they can do so only so far as they are laid to heart in +their purity as motives, unmixed with any view to prosperity, for it +is in suffering that they display themselves most nobly. Now that +whose removal strengthens the effect of a moving force must have +been a hindrance, consequently every admixture of motives taken from +our own happiness is a hindrance to the influence of the moral law +on the heart. I affirm further that even in that admired action, if +the motive from which it was done was a high regard for duty, then +it is just this respect for the law that has the greatest influence on +the mind of the spectator, not any pretension to a supposed inward +greatness of mind or noble meritorious sentiments; consequently +duty, not merit, must have not only the most definite, but, when it is +represented in the true light of its inviolability, the most +penetrating, influence on the mind. + +It is more necessary than ever to direct attention to this method in +our times, when men hope to produce more effect on the mind with soft, +tender feelings, or high-flown, puffing-up pretensions, which rather +wither the heart than strengthen it, than by a plain and earnest +representation of duty, which is more suited to human imperfection and +to progress in goodness. To set before children, as a pattern, actions +that are called noble, magnanimous, meritorious, with the notion of +captivating them by infusing enthusiasm for such actions, is to defeat +our end. For as they are still so backward in the observance of the +commonest duty, and even in the correct estimation of it, this means +simply to make them fantastical romancers betimes. But, even with +the instructed and experienced part of mankind, this supposed spring +has, if not an injurious, at least no genuine, moral effect on the +heart, which, however, is what it was desired to produce. + +All feelings, especially those that are to produce unwonted +exertions, must accomplish their effect at the moment they are at +their height and before the calm down; otherwise they effect +nothing; for as there was nothing to strengthen the heart, but only to +excite it, it naturally returns to its normal moderate tone and, thus, +falls back into its previous languor. Principles must be built on +conceptions; on any other basis there can only be paroxysms, which can +give the person no moral worth, nay, not even confidence in himself, +without which the highest good in man, consciousness of the morality +of his mind and character, cannot exist. Now if these conceptions +are to become subjectively practical, we must not rest satisfied +with admiring the objective law of morality, and esteeming it highly +in reference to humanity, but we must consider the conception of it in +relation to man as an individual, and then this law appears in a +form indeed that is highly deserving of respect, but not so pleasant +as if it belonged to the element to which he is naturally +accustomed; but on the contrary as often compelling him to quit this +element, not without self-denial, and to betake himself to a higher, +in which he can only maintain himself with trouble and with +unceasing apprehension of a relapse. In a word, the moral law +demands obedience, from duty not from predilection, which cannot and +ought not to be presupposed at all. + +Let us now see, in an example, whether the conception of an +action, as a noble and magnanimous one, has more subjective moving +power than if the action is conceived merely as duty in relation to +the solemn law of morality. The action by which a man endeavours at +the greatest peril of life to rescue people from shipwreck, at last +losing his life in the attempt, is reckoned on one side as duty, but +on the other and for the most part as a meritorious action, but our +esteem for it is much weakened by the notion of duty to himself +which seems in this case to be somewhat infringed. More decisive is +the magnanimous sacrifice of life for the safety of one's country; and +yet there still remains some scruple whether it is a perfect duty to +devote one's self to this purpose spontaneously and unbidden, and +the action has not in itself the full force of a pattern and impulse +to imitation. But if an indispensable duty be in question, the +transgression of which violates the moral law itself, and without +regard to the welfare of mankind, and as it were tramples on its +holiness (such as are usually called duties to God, because in Him +we conceive the ideal of holiness in substance), then we give our most +perfect esteem to the pursuit of it at the sacrifice of all that can +have any value for the dearest inclinations, and we find our soul +strengthened and elevated by such an example, when we convince +ourselves by contemplation of it that human nature is capable of so +great an elevation above every motive that nature can oppose to it. +Juvenal describes such an example in a climax which makes the reader +feel vividly the force of the spring that is contained in the pure law +of duty, as duty: + + + + {PART_2|METHODOLOGY ^paragraph 15} + + Esto bonus miles, tutor bonus, arbiter idem + + Integer; ambiguae si quando citabere testis + + Incertaeque rei, Phalaris licet imperet ut sis + + Falsus, et admoto dictet periuria tauro, + + Summum crede nefas animam praeferre pudori, + + {PART_2|METHODOLOGY ^paragraph 20} + + Et propter vitam vivendi perdere causas. * + + + +* [Juvenal, Satirae, "Be you a good soldier, a faithful tutor, an +uncorrupted umpire also; if you are summoned as a witness in a +doubtful and uncertain thing, though Phalaris should command that +you should be false, and should dictate perjuries with the bull +brought to you, believe it the highest impiety to prefer life to +reputation, and for the sake of life, to lose the causes of living."] + + + +When we can bring any flattering thought of merit into our action, +then the motive is already somewhat alloyed with self-love and has +therefore some assistance from the side of the sensibility. But to +postpone everything to the holiness of duty alone, and to be conscious +that we can because our own reason recognises this as its command +and says that we ought to do it, this is, as it were, to raise +ourselves altogether above the world of sense, and there is +inseparably involved in the same a consciousness of the law, as a +spring of a faculty that controls the sensibility; and although this +is not always attended with effect, yet frequent engagement with +this spring, and the at first minor attempts at using it, give hope +that this effect may be wrought, and that by degrees the greatest, and +that a purely moral interest in it may be produced in us. + + {PART_2|METHODOLOGY ^paragraph 25} + +The method then takes the following course. At first we are only +concerned to make the judging of actions by moral laws a natural +employment accompanying all our own free actions, as well as the +observation of those of others, and to make it as it were a habit, and +to sharpen this judgement, asking first whether the action conforms +objectively to the moral law, and to what law; and we distinguish +the law that merely furnishes a principle of obligation from that +which is really obligatory (leges obligandi a legibus obligantibus); +as, for instance, the law of what men's wants require from me, as +contrasted with that which their rights demand, the latter of which +prescribes essential, the former only non-essential duties; and thus +we teach how to distinguish different kinds of duties which meet in +the same action. The other point to which attention must be directed +is the question whether the action was also (subjectively) done for +the sake of the moral law, so that it not only is morally correct as a +deed, but also, by the maxim from which it is done, has moral worth as +a disposition. Now there is no doubt that this practice, and the +resulting culture of our reason in judging merely of the practical, +must gradually produce a certain interest even in the law of reason, +and consequently in morally good actions. For we ultimately take a +liking for a thing, the contemplation of which makes us feel that +the use of our cognitive faculties is extended; and this extension +is especially furthered by that in which we find moral correctness, +since it is only in such an order of things that reason, with its +faculty of determining a priori on principle what ought to be done, +can find satisfaction. An observer of nature takes liking at last to +objects that at first offended his senses, when he discovers in them +the great adaptation of their organization to design, so that his +reason finds food in its contemplation. So Leibnitz spared an insect +that he had carefully examined with the microscope, and replaced it on +its leaf, because he had found himself instructed by the view of it +and had, as it were, received a benefit from it. + +But this employment of the faculty of judgement, which makes us feel +our own cognitive powers, is not yet the interest in actions and in +their morality itself. It merely causes us to take pleasure in +engaging in such criticism, and it gives to virtue or the +disposition that conforms to moral laws a form of beauty, which is +admired, but not on that account sought after (laudatur et alget); +as everything the contemplation of which produces a consciousness of +the harmony of our powers of conception, and in which we feel the +whole of our faculty of knowledge (understanding and imagination) +strengthened, produces a satisfaction, which may also be +communicated to others, while nevertheless the existence of the object +remains indifferent to us, being only regarded as the occasion of +our becoming aware of the capacities in us which are elevated above +mere animal nature. Now, however, the second exercise comes in, the +living exhibition of morality of character by examples, in which +attention is directed to purity of will, first only as a negative +perfection, in so far as in an action done from duty no motives of +inclination have any influence in determining it. By this the +pupil's attention is fixed upon the consciousness of his freedom, +and although this renunciation at first excites a feeling of pain, +nevertheless, by its withdrawing the pupil from the constraint of even +real wants, there is proclaimed to him at the same time a +deliverance from the manifold dissatisfaction in which all these wants +entangle him, and the mind is made capable of receiving the +sensation of satisfaction from other sources. The heart is freed and +lightened of a burden that always secretly presses on it, when +instances of pure moral resolutions reveal to the man an inner faculty +of which otherwise he has no right knowledge, the inward freedom to +release himself from the boisterous importunity of inclinations, to +such a degree that none of them, not even the dearest, shall have +any influence on a resolution, for which we are now to employ our +reason. Suppose a case where I alone know that the wrong is on my +side, and although a free confession of it and the offer of +satisfaction are so strongly opposed by vanity, selfishness, and +even an otherwise not illegitimate antipathy to the man whose rights +are impaired by me, I am nevertheless able to discard all these +considerations; in this there is implied a consciousness of +independence on inclinations and circumstances, and of the possibility +of being sufficient for myself, which is salutary to me in general for +other purposes also. And now the law of duty, in consequence of the +positive worth which obedience to it makes us feel, finds easier +access through the respect for ourselves in the consciousness of our +freedom. When this is well established, when a man dreads nothing more +than to find himself, on self-examination, worthless and +contemptible in his own eyes, then every good moral disposition can be +grafted on it, because this is the best, nay, the only guard that +can keep off from the mind the pressure of ignoble and corrupting +motives. + +I have only intended to point out the most general maxims of the +methodology of moral cultivation and exercise. As the manifold variety +of duties requires special rules for each kind, and this would be a +prolix affair, I shall be readily excused if in a work like this, +which is only preliminary, I content myself with these outlines. + +PART_2|CONCLUSION + + CONCLUSION. + + + +Two things fill the mind with ever new and increasing admiration and +awe, the oftener and the more steadily we reflect on them: the +starry heavens above and the moral law within. I have not to search +for them and conjecture them as though they were veiled in darkness or +were in the transcendent region beyond my horizon; I see them before +me and connect them directly with the consciousness of my existence. +The former begins from the place I occupy in the external world of +sense, and enlarges my connection therein to an unbounded extent +with worlds upon worlds and systems of systems, and moreover into +limitless times of their periodic motion, its beginning and +continuance. The second begins from my invisible self, my personality, +and exhibits me in a world which has true infinity, but which is +traceable only by the understanding, and with which I discern that I +am not in a merely contingent but in a universal and necessary +connection, as I am also thereby with all those visible worlds. The +former view of a countless multitude of worlds annihilates as it +were my importance as an animal creature, which after it has been +for a short time provided with vital power, one knows not how, must +again give back the matter of which it was formed to the planet it +inhabits (a mere speck in the universe). The second, on the +contrary, infinitely elevates my worth as an intelligence by my +personality, in which the moral law reveals to me a life independent +of animality and even of the whole sensible world, at least so far +as may be inferred from the destination assigned to my existence by +this law, a destination not restricted to conditions and limits of +this life, but reaching into the infinite. + +But though admiration and respect may excite to inquiry, they cannot +supply the want of it. What, then, is to be done in order to enter +on this in a useful manner and one adapted to the loftiness of the +subject? Examples may serve in this as a warning and also for +imitation. The contemplation of the world began from the noblest +spectacle that the human senses present to us, and that our +understanding can bear to follow in their vast reach; and it ended- in +astrology. Morality began with the noblest attribute of human +nature, the development and cultivation of which give a prospect of +infinite utility; and ended- in fanaticism or superstition. So it is +with all crude attempts where the principal part of the business +depends on the use of reason, a use which does not come of itself, +like the use of the feet, by frequent exercise, especially when +attributes are in question which cannot be directly exhibited in +common experience. But after the maxim had come into vogue, though +late, to examine carefully beforehand all the steps that reason +purposes to take, and not to let it proceed otherwise than in the +track of a previously well considered method, then the study of the +structure of the universe took quite a different direction, and +thereby attained an incomparably happier result. The fall of a +stone, the motion of a sling, resolved into their elements and the +forces that are manifested in them, and treated mathematically, +produced at last that clear and henceforward unchangeable insight into +the system of the world which, as observation is continued, may hope +always to extend itself, but need never fear to be compelled to +retreat. + +This example may suggest to us to enter on the same path in treating +of the moral capacities of our nature, and may give us hope of a +like good result. We have at hand the instances of the moral judgement +of reason. By analysing these into their elementary conceptions, and +in default of mathematics adopting a process similar to that of +chemistry, the separation of the empirical from the rational +elements that may be found in them, by repeated experiments on +common sense, we may exhibit both pure, and learn with certainty +what each part can accomplish of itself, so as to prevent on the one +hand the errors of a still crude untrained judgement, and on the other +hand (what is far more necessary) the extravagances of genius, by +which, as by the adepts of the philosopher's stone, without any +methodical study or knowledge of nature, visionary treasures are +promised and the true are thrown away. In one word, science +(critically undertaken and methodically directed) is the narrow gate +that leads to the true doctrine of practical wisdom, if we +understand by this not merely what one ought to do, but what ought +to serve teachers as a guide to construct well and clearly the road to +wisdom which everyone should travel, and to secure others from going +astray. Philosophy must always continue to be the guardian of this +science; and although the public does not take any interest in its +subtle investigations, it must take an interest in the resulting +doctrines, which such an examination first puts in a clear light. + + + THE END + + + + + + + + +End of Project Gutenberg's The Critique of Practical Reason, by Immanuel Kant + +*** END OF THIS PROJECT GUTENBERG EBOOK THE CRITIQUE OF PRACTICAL REASON *** + +***** This file should be named 5683.txt or 5683.zip ***** +This and all associated files of various formats will be found in: + http://www.gutenberg.org/5/6/8/5683/ + +Produced by Matthew Stapleton + +Updated editions will replace the previous one--the old editions +will be renamed. + +Creating the works from public domain print editions means that no +one owns a United States copyright in these works, so the Foundation +(and you!) can copy and distribute it in the United States without +permission and without paying copyright royalties.

General Information About Project Gutenberg-tm electronic +works. + +Professor Michael S. Hart is the originator of the Project Gutenberg-tm +concept of a library of electronic works that could be freely shared +with anyone. For thirty years, he produced and distributed Project +Gutenberg-tm eBooks with only a loose network of volunteer support. + + +Project Gutenberg-tm eBooks are often created from several printed +editions, all of which are confirmed as Public Domain in the U.S. +unless a copyright notice is included. Thus, we do not necessarily +keep eBooks in compliance with any particular paper edition. + + +Most people start at our Web site which has the main PG search facility: + + http://www.gutenberg.org + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. |
