+ <h2>
+ PREFACE
+ </h2>
+ <p>
+ Ancient Greek philosophy was divided into three sciences: physics, ethics,
+ and logic. This division is perfectly suitable to the nature of the thing;
+ and the only improvement that can be made in it is to add the principle on
+ which it is based, so that we may both satisfy ourselves of its
+ completeness, and also be able to determine correctly the necessary
+ subdivisions.
+ </p>
+ <p>
+ All rational knowledge is either material or formal: the former considers
+ some object, the latter is concerned only with the form of the
+ understanding and of the reason itself, and with the universal laws of
+ thought in general without distinction of its objects. Formal philosophy
+ is called logic. Material philosophy, however, which has to do with
+ determinate objects and the laws to which they are subject, is again
+ twofold; for these laws are either laws of nature or of freedom. The
+ science of the former is physics, that of the latter, ethics; they are
+ also called natural philosophy and moral philosophy respectively.
+ </p>
+ <p>
+ Logic cannot have any empirical part; that is, a part in which the
+ universal and necessary laws of thought should rest on grounds taken from
+ experience; otherwise it would not be logic, i.e., a canon for the
+ understanding or the reason, valid for all thought, and capable of
+ demonstration. Natural and moral philosophy, on the contrary, can each
+ have their empirical part, since the former has to determine the laws of
+ nature as an object of experience; the latter the laws of the human will,
+ so far as it is affected by nature: the former, however, being laws
+ according to which everything does happen; the latter, laws according to
+ which everything ought to happen. Ethics, however, must also consider the
+ conditions under which what ought to happen frequently does not.
+ </p>
+ <p>
+ We may call all philosophy empirical, so far as it is based on grounds of
+ experience: on the other hand, that which delivers its doctrines from a
+ priori principles alone we may call pure philosophy. When the latter is
+ merely formal it is logic; if it is restricted to definite objects of the
+ understanding it is metaphysic.
+ </p>
+ <p>
+ In this way there arises the idea of a twofold metaphysic&mdash;a
+ metaphysic of nature and a metaphysic of morals. Physics will thus have an
+ empirical and also a rational part. It is the same with Ethics; but here
+ the empirical part might have the special name of practical anthropology,
+ the name morality being appropriated to the rational part.
+ </p>
+ <p>
+ All trades, arts, and handiworks have gained by division of labour,
+ namely, when, instead of one man doing everything, each confines himself
+ to a certain kind of work distinct from others in the treatment it
+ requires, so as to be able to perform it with greater facility and in the
+ greatest perfection. Where the different kinds of work are not
+ distinguished and divided, where everyone is a jack-of-all-trades, there
+ manufactures remain still in the greatest barbarism. It might deserve to
+ be considered whether pure philosophy in all its parts does not require a
+ man specially devoted to it, and whether it would not be better for the
+ whole business of science if those who, to please the tastes of the
+ public, are wont to blend the rational and empirical elements together,
+ mixed in all sorts of proportions unknown to themselves, and who call
+ themselves independent thinkers, giving the name of minute philosophers to
+ those who apply themselves to the rational part only- if these, I say,
+ were warned not to carry on two employments together which differ widely
+ in the treatment they demand, for each of which perhaps a special talent
+ is required, and the combination of which in one person only produces
+ bunglers. But I only ask here whether the nature of science does not
+ require that we should always carefully separate the empirical from the
+ rational part, and prefix to Physics proper (or empirical physics) a
+ metaphysic of nature, and to practical anthropology a metaphysic of
+ morals, which must be carefully cleared of everything empirical, so that
+ we may know how much can be accomplished by pure reason in both cases, and
+ from what sources it draws this its a priori teaching, and that whether
+ the latter inquiry is conducted by all moralists (whose name is legion),
+ or only by some who feel a calling thereto.
+ </p>
+ <p>
+ As my concern here is with moral philosophy, I limit the question
+ suggested to this: Whether it is not of the utmost necessity to construct
+ a pure thing which is only empirical and which belongs to anthropology?
+ for that such a philosophy must be possible is evident from the common
+ idea of duty and of the moral laws. Everyone must admit that if a law is
+ to have moral force, i.e., to be the basis of an obligation, it must carry
+ with it absolute necessity; that, for example, the precept, "Thou shalt
+ not lie," is not valid for men alone, as if other rational beings had no
+ need to observe it; and so with all the other moral laws properly so
+ called; that, therefore, the basis of obligation must not be sought in the
+ nature of man, or in the circumstances in the world in which he is placed,
+ but a priori simply in the conception of pure reason; and although any
+ other precept which is founded on principles of mere experience may be in
+ certain respects universal, yet in as far as it rests even in the least
+ degree on an empirical basis, perhaps only as to a motive, such a precept,
+ while it may be a practical rule, can never be called a moral law.
+ </p>
+ <p>
+ Thus not only are moral laws with their principles essentially
+ distinguished from every other kind of practical knowledge in which there
+ is anything empirical, but all moral philosophy rests wholly on its pure
+ part. When applied to man, it does not borrow the least thing from the
+ knowledge of man himself (anthropology), but gives laws a priori to him as
+ a rational being. No doubt these laws require a judgement sharpened by
+ experience, in order on the one hand to distinguish in what cases they are
+ applicable, and on the other to procure for them access to the will of the
+ man and effectual influence on conduct; since man is acted on by so many
+ inclinations that, though capable of the idea of a practical pure reason,
+ he is not so easily able to make it effective in concreto in his life.
+ </p>
+ <p>
+ A metaphysic of morals is therefore indispensably necessary, not merely
+ for speculative reasons, in order to investigate the sources of the
+ practical principles which are to be found a priori in our reason, but
+ also because morals themselves are liable to all sorts of corruption, as
+ long as we are without that clue and supreme canon by which to estimate
+ them correctly. For in order that an action should be morally good, it is
+ not enough that it conform to the moral law, but it must also be done for
+ the sake of the law, otherwise that conformity is only very contingent and
+ uncertain; since a principle which is not moral, although it may now and
+ then produce actions conformable to the law, will also often produce
+ actions which contradict it. Now it is only in a pure philosophy that we
+ can look for the moral law in its purity and genuineness (and, in a
+ practical matter, this is of the utmost consequence): we must, therefore,
+ begin with pure philosophy (metaphysic), and without it there cannot be
+ any moral philosophy at all. That which mingles these pure principles with
+ the empirical does not deserve the name of philosophy (for what
+ distinguishes philosophy from common rational knowledge is that it treats
+ in separate sciences what the latter only comprehends confusedly); much
+ less does it deserve that of moral philosophy, since by this confusion it
+ even spoils the purity of morals themselves, and counteracts its own end.
+ </p>
+ <p>
+ Let it not be thought, however, that what is here demanded is already
+ extant in the propaedeutic prefixed by the celebrated Wolf to his moral
+ philosophy, namely, his so-called general practical philosophy, and that,
+ therefore, we have not to strike into an entirely new field. Just because
+ it was to be a general practical philosophy, it has not taken into
+ consideration a will of any particular kind- say one which should be
+ determined solely from a priori principles without any empirical motives,
+ and which we might call a pure will, but volition in general, with all the
+ actions and conditions which belong to it in this general signification.
+ By this it is distinguished from a metaphysic of morals, just as general
+ logic, which treats of the acts and canons of thought in general, is
+ distinguished from transcendental philosophy, which treats of the
+ particular acts and canons of pure thought, i.e., that whose cognitions
+ are altogether a priori. For the metaphysic of morals has to examine the
+ idea and the principles of a possible pure will, and not the acts and
+ conditions of human volition generally, which for the most part are drawn
+ from psychology. It is true that moral laws and duty are spoken of in the
+ general moral philosophy (contrary indeed to all fitness). But this is no
+ objection, for in this respect also the authors of that science remain
+ true to their idea of it; they do not distinguish the motives which are
+ prescribed as such by reason alone altogether a priori, and which are
+ properly moral, from the empirical motives which the understanding raises
+ to general conceptions merely by comparison of experiences; but, without
+ noticing the difference of their sources, and looking on them all as
+ homogeneous, they consider only their greater or less amount. It is in
+ this way they frame their notion of obligation, which, though anything but
+ moral, is all that can be attained in a philosophy which passes no
+ judgement at all on the origin of all possible practical concepts, whether
+ they are a priori, or only a posteriori.
+ </p>
+ <p>
+ Intending to publish hereafter a metaphysic of morals, I issue in the
+ first instance these fundamental principles. Indeed there is properly no
+ other foundation for it than the critical examination of a pure practical
+ reason; just as that of metaphysics is the critical examination of the
+ pure speculative reason, already published. But in the first place the
+ former is not so absolutely necessary as the latter, because in moral
+ concerns human reason can easily be brought to a high degree of
+ correctness and completeness, even in the commonest understanding, while
+ on the contrary in its theoretic but pure use it is wholly dialectical;
+ and in the second place if the critique of a pure practical Reason is to
+ be complete, it must be possible at the same time to show its identity
+ with the speculative reason in a common principle, for it can ultimately
+ be only one and the same reason which has to be distinguished merely in
+ its application. I could not, however, bring it to such completeness here,
+ without introducing considerations of a wholly different kind, which would
+ be perplexing to the reader. On this account I have adopted the title of
+ Fundamental Principles of the Metaphysic of Morals instead of that of a
+ Critical Examination of the pure practical reason.
+ </p>
+ <p>
+ But in the third place, since a metaphysic of morals, in spite of the
+ discouraging title, is yet capable of being presented in popular form, and
+ one adapted to the common understanding, I find it useful to separate from
+ it this preliminary treatise on its fundamental principles, in order that
+ I may not hereafter have need to introduce these necessarily subtle
+ discussions into a book of a more simple character.
+ </p>
+ <p>
+ The present treatise is, however, nothing more than the investigation and
+ establishment of the supreme principle of morality, and this alone
+ constitutes a study complete in itself and one which ought to be kept
+ apart from every other moral investigation. No doubt my conclusions on
+ this weighty question, which has hitherto been very unsatisfactorily
+ examined, would receive much light from the application of the same
+ principle to the whole system, and would be greatly confirmed by the
+ adequacy which it exhibits throughout; but I must forego this advantage,
+ which indeed would be after all more gratifying than useful, since the
+ easy applicability of a principle and its apparent adequacy give no very
+ certain proof of its soundness, but rather inspire a certain partiality,
+ which prevents us from examining and estimating it strictly in itself and
+ without regard to consequences.
+ </p>
+ <p>
+ I have adopted in this work the method which I think most suitable,
+ proceeding analytically from common knowledge to the determination of its
+ ultimate principle, and again descending synthetically from the
+ examination of this principle and its sources to the common knowledge in
+ which we find it employed. The division will, therefore, be as follows:
+ </p>
+ <p>
+ 1 FIRST SECTION. Transition from the common rational knowledge of morality
+ to the philosophical.
+ </p>
+ <p>
+ 2 SECOND SECTION. Transition from popular moral philosophy to the
+ metaphysic of morals.
+ </p>
+ <p>
+ 3 THIRD SECTION. Final step from the metaphysic of morals to the critique
+ of the pure practical reason.

+ <h2>
+ FIRST SECTION&mdash;TRANSITION FROM THE COMMON RATIONAL KNOWLEDGE OF
+ MORALITY TO THE PHILOSOPHICAL
+ </h2>
+ <p>
+ Nothing can possibly be conceived in the world, or even out of it, which
+ can be called good, without qualification, except a good will.
+ Intelligence, wit, judgement, and the other talents of the mind, however
+ they may be named, or courage, resolution, perseverance, as qualities of
+ temperament, are undoubtedly good and desirable in many respects; but
+ these gifts of nature may also become extremely bad and mischievous if the
+ will which is to make use of them, and which, therefore, constitutes what
+ is called character, is not good. It is the same with the gifts of
+ fortune. Power, riches, honour, even health, and the general well-being
+ and contentment with one's condition which is called happiness, inspire
+ pride, and often presumption, if there is not a good will to correct the
+ influence of these on the mind, and with this also to rectify the whole
+ principle of acting and adapt it to its end. The sight of a being who is
+ not adorned with a single feature of a pure and good will, enjoying
+ unbroken prosperity, can never give pleasure to an impartial rational
+ spectator. Thus a good will appears to constitute the indispensable
+ condition even of being worthy of happiness.
+ </p>
+ <p>
+ There are even some qualities which are of service to this good will
+ itself and may facilitate its action, yet which have no intrinsic
+ unconditional value, but always presuppose a good will, and this qualifies
+ the esteem that we justly have for them and does not permit us to regard
+ them as absolutely good. Moderation in the affections and passions,
+ self-control, and calm deliberation are not only good in many respects,
+ but even seem to constitute part of the intrinsic worth of the person; but
+ they are far from deserving to be called good without qualification,
+ although they have been so unconditionally praised by the ancients. For
+ without the principles of a good will, they may become extremely bad, and
+ the coolness of a villain not only makes him far more dangerous, but also
+ directly makes him more abominable in our eyes than he would have been
+ without it.
+ </p>
+ <p>
+ A good will is good not because of what it performs or effects, not by its
+ aptness for the attainment of some proposed end, but simply by virtue of
+ the volition; that is, it is good in itself, and considered by itself is
+ to be esteemed much higher than all that can be brought about by it in
+ favour of any inclination, nay even of the sum total of all inclinations.
+ Even if it should happen that, owing to special disfavour of fortune, or
+ the niggardly provision of a step-motherly nature, this will should wholly
+ lack power to accomplish its purpose, if with its greatest efforts it
+ should yet achieve nothing, and there should remain only the good will
+ (not, to be sure, a mere wish, but the summoning of all means in our
+ power), then, like a jewel, it would still shine by its own light, as a
+ thing which has its whole value in itself. Its usefulness or fruitlessness
+ can neither add nor take away anything from this value. It would be, as it
+ were, only the setting to enable us to handle it the more conveniently in
+ common commerce, or to attract to it the attention of those who are not
+ yet connoisseurs, but not to recommend it to true connoisseurs, or to
+ determine its value.
+ </p>
+ <p>
+ There is, however, something so strange in this idea of the absolute value
+ of the mere will, in which no account is taken of its utility, that
+ notwithstanding the thorough assent of even common reason to the idea, yet
+ a suspicion must arise that it may perhaps really be the product of mere
+ high-flown fancy, and that we may have misunderstood the purpose of nature
+ in assigning reason as the governor of our will. Therefore we will examine
+ this idea from this point of view.
+ </p>
+ <p>
+ In the physical constitution of an organized being, that is, a being
+ adapted suitably to the purposes of life, we assume it as a fundamental
+ principle that no organ for any purpose will be found but what is also the
+ fittest and best adapted for that purpose. Now in a being which has reason
+ and a will, if the proper object of nature were its conservation, its
+ welfare, in a word, its happiness, then nature would have hit upon a very
+ bad arrangement in selecting the reason of the creature to carry out this
+ purpose. For all the actions which the creature has to perform with a view
+ to this purpose, and the whole rule of its conduct, would be far more
+ surely prescribed to it by instinct, and that end would have been attained
+ thereby much more certainly than it ever can be by reason. Should reason
+ have been communicated to this favoured creature over and above, it must
+ only have served it to contemplate the happy constitution of its nature,
+ to admire it, to congratulate itself thereon, and to feel thankful for it
+ to the beneficent cause, but not that it should subject its desires to
+ that weak and delusive guidance and meddle bunglingly with the purpose of
+ nature. In a word, nature would have taken care that reason should not
+ break forth into practical exercise, nor have the presumption, with its
+ weak insight, to think out for itself the plan of happiness, and of the
+ means of attaining it. Nature would not only have taken on herself the
+ choice of the ends, but also of the means, and with wise foresight would
+ have entrusted both to instinct.
+ </p>
+ <p>
+ And, in fact, we find that the more a cultivated reason applies itself
+ with deliberate purpose to the enjoyment of life and happiness, so much
+ the more does the man fail of true satisfaction. And from this
+ circumstance there arises in many, if they are candid enough to confess
+ it, a certain degree of misology, that is, hatred of reason, especially in
+ the case of those who are most experienced in the use of it, because after
+ calculating all the advantages they derive, I do not say from the
+ invention of all the arts of common luxury, but even from the sciences
+ (which seem to them to be after all only a luxury of the understanding),
+ they find that they have, in fact, only brought more trouble on their
+ shoulders, rather than gained in happiness; and they end by envying,
+ rather than despising, the more common stamp of men who keep closer to the
+ guidance of mere instinct and do not allow their reason much influence on
+ their conduct. And this we must admit, that the judgement of those who
+ would very much lower the lofty eulogies of the advantages which reason
+ gives us in regard to the happiness and satisfaction of life, or who would
+ even reduce them below zero, is by no means morose or ungrateful to the
+ goodness with which the world is governed, but that there lies at the root
+ of these judgements the idea that our existence has a different and far
+ nobler end, for which, and not for happiness, reason is properly intended,
+ and which must, therefore, be regarded as the supreme condition to which
+ the private ends of man must, for the most part, be postponed.
+ </p>
+ <p>
+ For as reason is not competent to guide the will with certainty in regard
+ to its objects and the satisfaction of all our wants (which it to some
+ extent even multiplies), this being an end to which an implanted instinct
+ would have led with much greater certainty; and since, nevertheless,
+ reason is imparted to us as a practical faculty, i.e., as one which is to
+ have influence on the will, therefore, admitting that nature generally in
+ the distribution of her capacities has adapted the means to the end, its
+ true destination must be to produce a will, not merely good as a means to
+ something else, but good in itself, for which reason was absolutely
+ necessary. This will then, though not indeed the sole and complete good,
+ must be the supreme good and the condition of every other, even of the
+ desire of happiness. Under these circumstances, there is nothing
+ inconsistent with the wisdom of nature in the fact that the cultivation of
+ the reason, which is requisite for the first and unconditional purpose,
+ does in many ways interfere, at least in this life, with the attainment of
+ the second, which is always conditional, namely, happiness. Nay, it may
+ even reduce it to nothing, without nature thereby failing of her purpose.
+ For reason recognizes the establishment of a good will as its highest
+ practical destination, and in attaining this purpose is capable only of a
+ satisfaction of its own proper kind, namely that from the attainment of an
+ end, which end again is determined by reason only, notwithstanding that
+ this may involve many a disappointment to the ends of inclination.
+ </p>
+ <p>
+ We have then to develop the notion of a will which deserves to be highly
+ esteemed for itself and is good without a view to anything further, a
+ notion which exists already in the sound natural understanding, requiring
+ rather to be cleared up than to be taught, and which in estimating the
+ value of our actions always takes the first place and constitutes the
+ condition of all the rest. In order to do this, we will take the notion of
+ duty, which includes that of a good will, although implying certain
+ subjective restrictions and hindrances. These, however, far from
+ concealing it, or rendering it unrecognizable, rather bring it out by
+ contrast and make it shine forth so much the brighter.
+ </p>
+ <p>
+ I omit here all actions which are already recognized as inconsistent with
+ duty, although they may be useful for this or that purpose, for with these
+ the question whether they are done from duty cannot arise at all, since
+ they even conflict with it. I also set aside those actions which really
+ conform to duty, but to which men have no direct inclination, performing
+ them because they are impelled thereto by some other inclination. For in
+ this case we can readily distinguish whether the action which agrees with
+ duty is done from duty, or from a selfish view. It is much harder to make
+ this distinction when the action accords with duty and the subject has
+ besides a direct inclination to it. For example, it is always a matter of
+ duty that a dealer should not over charge an inexperienced purchaser; and
+ wherever there is much commerce the prudent tradesman does not overcharge,
+ but keeps a fixed price for everyone, so that a child buys of him as well
+ as any other. Men are thus honestly served; but this is not enough to make
+ us believe that the tradesman has so acted from duty and from principles
+ of honesty: his own advantage required it; it is out of the question in
+ this case to suppose that he might besides have a direct inclination in
+ favour of the buyers, so that, as it were, from love he should give no
+ advantage to one over another. Accordingly the action was done neither
+ from duty nor from direct inclination, but merely with a selfish view.
+ </p>
+ <p>
+ On the other hand, it is a duty to maintain one's life; and, in addition,
+ everyone has also a direct inclination to do so. But on this account the
+ often anxious care which most men take for it has no intrinsic worth, and
+ their maxim has no moral import. They preserve their life as duty
+ requires, no doubt, but not because duty requires. On the other hand, if
+ adversity and hopeless sorrow have completely taken away the relish for
+ life; if the unfortunate one, strong in mind, indignant at his fate rather
+ than desponding or dejected, wishes for death, and yet preserves his life
+ without loving it- not from inclination or fear, but from duty- then his
+ maxim has a moral worth.
+ </p>
+ <p>
+ To be beneficent when we can is a duty; and besides this, there are many
+ minds so sympathetically constituted that, without any other motive of
+ vanity or self-interest, they find a pleasure in spreading joy around them
+ and can take delight in the satisfaction of others so far as it is their
+ own work. But I maintain that in such a case an action of this kind,
+ however proper, however amiable it may be, has nevertheless no true moral
+ worth, but is on a level with other inclinations, e.g., the inclination to
+ honour, which, if it is happily directed to that which is in fact of
+ public utility and accordant with duty and consequently honourable,
+ deserves praise and encouragement, but not esteem. For the maxim lacks the
+ moral import, namely, that such actions be done from duty, not from
+ inclination. Put the case that the mind of that philanthropist were
+ clouded by sorrow of his own, extinguishing all sympathy with the lot of
+ others, and that, while he still has the power to benefit others in
+ distress, he is not touched by their trouble because he is absorbed with
+ his own; and now suppose that he tears himself out of this dead
+ insensibility, and performs the action without any inclination to it, but
+ simply from duty, then first has his action its genuine moral worth.
+ Further still; if nature has put little sympathy in the heart of this or
+ that man; if he, supposed to be an upright man, is by temperament cold and
+ indifferent to the sufferings of others, perhaps because in respect of his
+ own he is provided with the special gift of patience and fortitude and
+ supposes, or even requires, that others should have the same- and such a
+ man would certainly not be the meanest product of nature- but if nature
+ had not specially framed him for a philanthropist, would he not still find
+ in himself a source from whence to give himself a far higher worth than
+ that of a good-natured temperament could be? Unquestionably. It is just in
+ this that the moral worth of the character is brought out which is
+ incomparably the highest of all, namely, that he is beneficent, not from
+ inclination, but from duty.
+ </p>
+ <p>
+ To secure one's own happiness is a duty, at least indirectly; for
+ discontent with one's condition, under a pressure of many anxieties and
+ amidst unsatisfied wants, might easily become a great temptation to
+ transgression of duty. But here again, without looking to duty, all men
+ have already the strongest and most intimate inclination to happiness,
+ because it is just in this idea that all inclinations are combined in one
+ total. But the precept of happiness is often of such a sort that it
+ greatly interferes with some inclinations, and yet a man cannot form any
+ definite and certain conception of the sum of satisfaction of all of them
+ which is called happiness. It is not then to be wondered at that a single
+ inclination, definite both as to what it promises and as to the time
+ within which it can be gratified, is often able to overcome such a
+ fluctuating idea, and that a gouty patient, for instance, can choose to
+ enjoy what he likes, and to suffer what he may, since, according to his
+ calculation, on this occasion at least, he has not sacrificed the
+ enjoyment of the present moment to a possibly mistaken expectation of a
+ happiness which is supposed to be found in health. But even in this case,
+ if the general desire for happiness did not influence his will, and
+ supposing that in his particular case health was not a necessary element
+ in this calculation, there yet remains in this, as in all other cases,
+ this law, namely, that he should promote his happiness not from
+ inclination but from duty, and by this would his conduct first acquire
+ true moral worth.
+ </p>
+ <p>
+ It is in this manner, undoubtedly, that we are to understand those
+ passages of Scripture also in which we are commanded to love our
+ neighbour, even our enemy. For love, as an affection, cannot be commanded,
+ but beneficence for duty's sake may; even though we are not impelled to it
+ by any inclination- nay, are even repelled by a natural and unconquerable
+ aversion. This is practical love and not pathological- a love which is
+ seated in the will, and not in the propensions of sense- in principles of
+ action and not of tender sympathy; and it is this love alone which can be
+ commanded.
+ </p>
+ <p>
+ The second proposition is: That an action done from duty derives its moral
+ worth, not from the purpose which is to be attained by it, but from the
+ maxim by which it is determined, and therefore does not depend on the
+ realization of the object of the action, but merely on the principle of
+ volition by which the action has taken place, without regard to any object
+ of desire. It is clear from what precedes that the purposes which we may
+ have in view in our actions, or their effects regarded as ends and springs
+ of the will, cannot give to actions any unconditional or moral worth. In
+ what, then, can their worth lie, if it is not to consist in the will and
+ in reference to its expected effect? It cannot lie anywhere but in the
+ principle of the will without regard to the ends which can be attained by
+ the action. For the will stands between its a priori principle, which is
+ formal, and its a posteriori spring, which is material, as between two
+ roads, and as it must be determined by something, it follows that it must
+ be determined by the formal principle of volition when an action is done
+ from duty, in which case every material principle has been withdrawn from
+ it.
+ </p>
+ <p>
+ The third proposition, which is a consequence of the two preceding, I
+ would express thus: Duty is the necessity of acting from respect for the
+ law. I may have inclination for an object as the effect of my proposed
+ action, but I cannot have respect for it, just for this reason, that it is
+ an effect and not an energy of will. Similarly I cannot have respect for
+ inclination, whether my own or another's; I can at most, if my own,
+ approve it; if another's, sometimes even love it; i.e., look on it as
+ favourable to my own interest. It is only what is connected with my will
+ as a principle, by no means as an effect- what does not subserve my
+ inclination, but overpowers it, or at least in case of choice excludes it
+ from its calculation- in other words, simply the law of itself, which can
+ be an object of respect, and hence a command. Now an action done from duty
+ must wholly exclude the influence of inclination and with it every object
+ of the will, so that nothing remains which can determine the will except
+ objectively the law, and subjectively pure respect for this practical law,
+ and consequently the maxim * that I should follow this law even to the
+ thwarting of all my inclinations.
+ </p>
+<pre xml:space="preserve">
+ * A maxim is the subjective principle of volition. The
+ objective principle (i.e., that which would also serve
+ subjectively as a practical principle to all rational beings
+ if reason had full power over the faculty of desire) is the
+ practical law.
+</pre>
+ <p>
+ Thus the moral worth of an action does not lie in the effect expected from
+ it, nor in any principle of action which requires to borrow its motive
+ from this expected effect. For all these effects- agreeableness of one's
+ condition and even the promotion of the happiness of others- could have
+ been also brought about by other causes, so that for this there would have
+ been no need of the will of a rational being; whereas it is in this alone
+ that the supreme and unconditional good can be found. The pre-eminent good
+ which we call moral can therefore consist in nothing else than the
+ conception of law in itself, which certainly is only possible in a
+ rational being, in so far as this conception, and not the expected effect,
+ determines the will. This is a good which is already present in the person
+ who acts accordingly, and we have not to wait for it to appear first in
+ the result. *
+ </p>
+<pre xml:space="preserve">
+ * It might be here objected to me that I take refuge behind
+ the word respect in an obscure feeling, instead of giving a
+ distinct solution of the question by a concept of the
+ reason. But although respect is a feeling, it is not a
+ feeling received through influence, but is self-wrought by a
+ rational concept, and, therefore, is specifically distinct
+ from all feelings of the former kind, which may be referred
+ either to inclination or fear, What I recognise immediately
+ as a law for me, I recognise with respect. This merely
+ signifies the consciousness that my will is subordinate to a
+ law, without the intervention of other influences on my
+ sense. The immediate determination of the will by the law,
+ and the consciousness of this, is called respect, so that
+ this is regarded as an effect of the law on the subject, and
+ not as the cause of it. Respect is properly the conception
+ of a worth which thwarts my self-love. Accordingly it is
+ something which is considered neither as an object of
+ inclination nor of fear, although it has something analogous
+ to both. The object of respect is the law only, and that the
+ law which we impose on ourselves and yet recognise as
+ necessary in itself. As a law, we are subjected too it
+ without consulting self-love; as imposed by us on ourselves,
+ it is a result of our will. In the former aspect it has an
+ analogy to fear, in the latter to inclination. Respect for a
+ person is properly only respect for the law (of honesty,
+ etc.) of which he gives us an example. Since we also look on
+ the improvement of our talents as a duty, we consider that
+ we see in a person of talents, as it were, the example of a
+ law (viz., to become like him in this by exercise), and this
+ constitutes our respect. All so-called moral interest
+ consists simply in respect for the law.
+</pre>
+ <p>
+ But what sort of law can that be, the conception of which must determine
+ the will, even without paying any regard to the effect expected from it,
+ in order that this will may be called good absolutely and without
+ qualification? As I have deprived the will of every impulse which could
+ arise to it from obedience to any law, there remains nothing but the
+ universal conformity of its actions to law in general, which alone is to
+ serve the will as a principle, i.e., I am never to act otherwise than so
+ that I could also will that my maxim should become a universal law. Here,
+ now, it is the simple conformity to law in general, without assuming any
+ particular law applicable to certain actions, that serves the will as its
+ principle and must so serve it, if duty is not to be a vain delusion and a
+ chimerical notion. The common reason of men in its practical judgements
+ perfectly coincides with this and always has in view the principle here
+ suggested. Let the question be, for example: May I when in distress make a
+ promise with the intention not to keep it? I readily distinguish here
+ between the two significations which the question may have: Whether it is
+ prudent, or whether it is right, to make a false promise? The former may
+ undoubtedly often be the case. I see clearly indeed that it is not enough
+ to extricate myself from a present difficulty by means of this subterfuge,
+ but it must be well considered whether there may not hereafter spring from
+ this lie much greater inconvenience than that from which I now free
+ myself, and as, with all my supposed cunning, the consequences cannot be
+ so easily foreseen but that credit once lost may be much more injurious to
+ me than any mischief which I seek to avoid at present, it should be
+ considered whether it would not be more prudent to act herein according to
+ a universal maxim and to make it a habit to promise nothing except with
+ the intention of keeping it. But it is soon clear to me that such a maxim
+ will still only be based on the fear of consequences. Now it is a wholly
+ different thing to be truthful from duty and to be so from apprehension of
+ injurious consequences. In the first case, the very notion of the action
+ already implies a law for me; in the second case, I must first look about
+ elsewhere to see what results may be combined with it which would affect
+ myself. For to deviate from the principle of duty is beyond all doubt
+ wicked; but to be unfaithful to my maxim of prudence may often be very
+ advantageous to me, although to abide by it is certainly safer. The
+ shortest way, however, and an unerring one, to discover the answer to this
+ question whether a lying promise is consistent with duty, is to ask
+ myself, "Should I be content that my maxim (to extricate myself from
+ difficulty by a false promise) should hold good as a universal law, for
+ myself as well as for others?" and should I be able to say to myself,
+ "Every one may make a deceitful promise when he finds himself in a
+ difficulty from which he cannot otherwise extricate himself?" Then I
+ presently become aware that while I can will the lie, I can by no means
+ will that lying should be a universal law. For with such a law there would
+ be no promises at all, since it would be in vain to allege my intention in
+ regard to my future actions to those who would not believe this
+ allegation, or if they over hastily did so would pay me back in my own
+ coin. Hence my maxim, as soon as it should be made a universal law, would
+ necessarily destroy itself.
+ </p>
+ <p>
+ I do not, therefore, need any far-reaching penetration to discern what I
+ have to do in order that my will may be morally good. Inexperienced in the
+ course of the world, incapable of being prepared for all its
+ contingencies, I only ask myself: Canst thou also will that thy maxim
+ should be a universal law? If not, then it must be rejected, and that not
+ because of a disadvantage accruing from it to myself or even to others,
+ but because it cannot enter as a principle into a possible universal
+ legislation, and reason extorts from me immediate respect for such
+ legislation. I do not indeed as yet discern on what this respect is based
+ (this the philosopher may inquire), but at least I understand this, that
+ it is an estimation of the worth which far outweighs all worth of what is
+ recommended by inclination, and that the necessity of acting from pure
+ respect for the practical law is what constitutes duty, to which every
+ other motive must give place, because it is the condition of a will being
+ good in itself, and the worth of such a will is above everything.
+ </p>
+ <p>
+ Thus, then, without quitting the moral knowledge of common human reason,
+ we have arrived at its principle. And although, no doubt, common men do
+ not conceive it in such an abstract and universal form, yet they always
+ have it really before their eyes and use it as the standard of their
+ decision. Here it would be easy to show how, with this compass in hand,
+ men are well able to distinguish, in every case that occurs, what is good,
+ what bad, conformably to duty or inconsistent with it, if, without in the
+ least teaching them anything new, we only, like Socrates, direct their
+ attention to the principle they themselves employ; and that, therefore, we
+ do not need science and philosophy to know what we should do to be honest
+ and good, yea, even wise and virtuous. Indeed we might well have
+ conjectured beforehand that the knowledge of what every man is bound to
+ do, and therefore also to know, would be within the reach of every man,
+ even the commonest. Here we cannot forbear admiration when we see how
+ great an advantage the practical judgement has over the theoretical in the
+ common understanding of men. In the latter, if common reason ventures to
+ depart from the laws of experience and from the perceptions of the senses,
+ it falls into mere inconceivabilities and self-contradictions, at least
+ into a chaos of uncertainty, obscurity, and instability. But in the
+ practical sphere it is just when the common understanding excludes all
+ sensible springs from practical laws that its power of judgement begins to
+ show itself to advantage. It then becomes even subtle, whether it be that
+ it chicanes with its own conscience or with other claims respecting what
+ is to be called right, or whether it desires for its own instruction to
+ determine honestly the worth of actions; and, in the latter case, it may
+ even have as good a hope of hitting the mark as any philosopher whatever
+ can promise himself. Nay, it is almost more sure of doing so, because the
+ philosopher cannot have any other principle, while he may easily perplex
+ his judgement by a multitude of considerations foreign to the matter, and
+ so turn aside from the right way. Would it not therefore be wiser in moral
+ concerns to acquiesce in the judgement of common reason, or at most only
+ to call in philosophy for the purpose of rendering the system of morals
+ more complete and intelligible, and its rules more convenient for use
+ (especially for disputation), but not so as to draw off the common
+ understanding from its happy simplicity, or to bring it by means of
+ philosophy into a new path of inquiry and instruction?
+ </p>
+ <p>
+ Innocence is indeed a glorious thing; only, on the other hand, it is very
+ sad that it cannot well maintain itself and is easily seduced. On this
+ account even wisdom- which otherwise consists more in conduct than in
+ knowledge- yet has need of science, not in order to learn from it, but to
+ secure for its precepts admission and permanence. Against all the commands
+ of duty which reason represents to man as so deserving of respect, he
+ feels in himself a powerful counterpoise in his wants and inclinations,
+ the entire satisfaction of which he sums up under the name of happiness.
+ Now reason issues its commands unyieldingly, without promising anything to
+ the inclinations, and, as it were, with disregard and contempt for these
+ claims, which are so impetuous, and at the same time so plausible, and
+ which will not allow themselves to be suppressed by any command. Hence
+ there arises a natural dialectic, i.e., a disposition, to argue against
+ these strict laws of duty and to question their validity, or at least
+ their purity and strictness; and, if possible, to make them more accordant
+ with our wishes and inclinations, that is to say, to corrupt them at their
+ very source, and entirely to destroy their worth- a thing which even
+ common practical reason cannot ultimately call good.
+ </p>
+ <p>
+ Thus is the common reason of man compelled to go out of its sphere, and to
+ take a step into the field of a practical philosophy, not to satisfy any
+ speculative want (which never occurs to it as long as it is content to be
+ mere sound reason), but even on practical grounds, in order to attain in
+ it information and clear instruction respecting the source of its
+ principle, and the correct determination of it in opposition to the maxims
+ which are based on wants and inclinations, so that it may escape from the
+ perplexity of opposite claims and not run the risk of losing all genuine
+ moral principles through the equivocation into which it easily falls.
+ Thus, when practical reason cultivates itself, there insensibly arises in
+ it a dialetic which forces it to seek aid in philosophy, just as happens
+ to it in its theoretic use; and in this case, therefore, as well as in the
+ other, it will find rest nowhere but in a thorough critical examination of
+ our reason.

+ <h2>
+ SECOND SECTION&mdash;TRANSITION FROM POPULAR MORAL PHILOSOPHY TO THE
+ METAPHYSIC OF MORALS
+ </h2>
+ <p>
+ If we have hitherto drawn our notion of duty from the common use of our
+ practical reason, it is by no means to be inferred that we have treated it
+ as an empirical notion. On the contrary, if we attend to the experience of
+ men's conduct, we meet frequent and, as we ourselves allow, just
+ complaints that one cannot find a single certain example of the
+ disposition to act from pure duty. Although many things are done in
+ conformity with what duty prescribes, it is nevertheless always doubtful
+ whether they are done strictly from duty, so as to have a moral worth.
+ Hence there have at all times been philosophers who have altogether denied
+ that this disposition actually exists at all in human actions, and have
+ ascribed everything to a more or less refined self-love. Not that they
+ have on that account questioned the soundness of the conception of
+ morality; on the contrary, they spoke with sincere regret of the frailty
+ and corruption of human nature, which, though noble enough to take its
+ rule an idea so worthy of respect, is yet weak to follow it and employs
+ reason which ought to give it the law only for the purpose of providing
+ for the interest of the inclinations, whether singly or at the best in the
+ greatest possible harmony with one another.
+ </p>
+ <p>
+ In fact, it is absolutely impossible to make out by experience with
+ complete certainty a single case in which the maxim of an action, however
+ right in itself, rested simply on moral grounds and on the conception of
+ duty. Sometimes it happens that with the sharpest self-examination we can
+ find nothing beside the moral principle of duty which could have been
+ powerful enough to move us to this or that action and to so great a
+ sacrifice; yet we cannot from this infer with certainty that it was not
+ really some secret impulse of self-love, under the false appearance of
+ duty, that was the actual determining cause of the will. We like them to
+ flatter ourselves by falsely taking credit for a more noble motive;
+ whereas in fact we can never, even by the strictest examination, get
+ completely behind the secret springs of action; since, when the question
+ is of moral worth, it is not with the actions which we see that we are
+ concerned, but with those inward principles of them which we do not see.
+ </p>
+ <p>
+ Moreover, we cannot better serve the wishes of those who ridicule all
+ morality as a mere chimera of human imagination over stepping itself from
+ vanity, than by conceding to them that notions of duty must be drawn only
+ from experience (as from indolence, people are ready to think is also the
+ case with all other notions); for or is to prepare for them a certain
+ triumph. I am willing to admit out of love of humanity that even most of
+ our actions are correct, but if we look closer at them we everywhere come
+ upon the dear self which is always prominent, and it is this they have in
+ view and not the strict command of duty which would often require
+ self-denial. Without being an enemy of virtue, a cool observer, one that
+ does not mistake the wish for good, however lively, for its reality, may
+ sometimes doubt whether true virtue is actually found anywhere in the
+ world, and this especially as years increase and the judgement is partly
+ made wiser by experience and partly, also, more acute in observation. This
+ being so, nothing can secure us from falling away altogether from our
+ ideas of duty, or maintain in the soul a well-grounded respect for its
+ law, but the clear conviction that although there should never have been
+ actions which really sprang from such pure sources, yet whether this or
+ that takes place is not at all the question; but that reason of itself,
+ independent on all experience, ordains what ought to take place, that
+ accordingly actions of which perhaps the world has hitherto never given an
+ example, the feasibility even of which might be very much doubted by one
+ who founds everything on experience, are nevertheless inflexibly commanded
+ by reason; that, e.g., even though there might never yet have been a
+ sincere friend, yet not a whit the less is pure sincerity in friendship
+ required of every man, because, prior to all experience, this duty is
+ involved as duty in the idea of a reason determining the will by a priori
+ principles.
+ </p>
+ <p>
+ When we add further that, unless we deny that the notion of morality has
+ any truth or reference to any possible object, we must admit that its law
+ must be valid, not merely for men but for all rational creatures
+ generally, not merely under certain contingent conditions or with
+ exceptions but with absolute necessity, then it is clear that no
+ experience could enable us to infer even the possibility of such
+ apodeictic laws. For with what right could we bring into unbounded respect
+ as a universal precept for every rational nature that which perhaps holds
+ only under the contingent conditions of humanity? Or how could laws of the
+ determination of our will be regarded as laws of the determination of the
+ will of rational beings generally, and for us only as such, if they were
+ merely empirical and did not take their origin wholly a priori from pure
+ but practical reason?
+ </p>
+ <p>
+ Nor could anything be more fatal to morality than that we should wish to
+ derive it from examples. For every example of it that is set before me
+ must be first itself tested by principles of morality, whether it is
+ worthy to serve as an original example, i.e., as a pattern; but by no
+ means can it authoritatively furnish the conception of morality. Even the
+ Holy One of the Gospels must first be compared with our ideal of moral
+ perfection before we can recognise Him as such; and so He says of Himself,
+ "Why call ye Me (whom you see) good; none is good (the model of good) but
+ God only (whom ye do not see)?" But whence have we the conception of God
+ as the supreme good? Simply from the idea of moral perfection, which
+ reason frames a priori and connects inseparably with the notion of a free
+ will. Imitation finds no place at all in morality, and examples serve only
+ for encouragement, i.e., they put beyond doubt the feasibility of what the
+ law commands, they make visible that which the practical rule expresses
+ more generally, but they can never authorize us to set aside the true
+ original which lies in reason and to guide ourselves by examples.
+ </p>
+ <p>
+ If then there is no genuine supreme principle of morality but what must
+ rest simply on pure reason, independent of all experience, I think it is
+ not necessary even to put the question whether it is good to exhibit these
+ concepts in their generality (in abstracto) as they are established a
+ priori along with the principles belonging to them, if our knowledge is to
+ be distinguished from the vulgar and to be called philosophical.
+ </p>
+ <p>
+ In our times indeed this might perhaps be necessary; for if we collected
+ votes whether pure rational knowledge separated from everything empirical,
+ that is to say, metaphysic of morals, or whether popular practical
+ philosophy is to be preferred, it is easy to guess which side would
+ preponderate.
+ </p>
+ <p>
+ This descending to popular notions is certainly very commendable, if the
+ ascent to the principles of pure reason has first taken place and been
+ satisfactorily accomplished. This implies that we first found ethics on
+ metaphysics, and then, when it is firmly established, procure a hearing
+ for it by giving it a popular character. But it is quite absurd to try to
+ be popular in the first inquiry, on which the soundness of the principles
+ depends. It is not only that this proceeding can never lay claim to the
+ very rare merit of a true philosophical popularity, since there is no art
+ in being intelligible if one renounces all thoroughness of insight; but
+ also it produces a disgusting medley of compiled observations and
+ half-reasoned principles. Shallow pates enjoy this because it can be used

+ We need only look at the attempts of moralists in that favourite fashion,
+ and we shall find at one time the special constitution of human nature
+ (including, however, the idea of a rational nature generally), at one time
+ perfection, at another happiness, here moral sense, there fear of God. a
+ little of this, and a little of that, in marvellous mixture, without its
+ occurring to them to ask whether the principles of morality are to be
+ sought in the knowledge of human nature at all (which we can have only
+ from experience); or, if this is not so, if these principles are to be
+ found altogether a priori, free from everything empirical, in pure
+ rational concepts only and nowhere else, not even in the smallest degree;
+ then rather to adopt the method of making this a separate inquiry, as pure
+ practical philosophy, or (if one may use a name so decried) as metaphysic
+ of morals, * to bring it by itself to completeness, and to require the
+ public, which wishes for popular treatment, to await the issue of this
+ undertaking.
+ </p>
+<pre xml:space="preserve">
+ * Just as pure mathematics are distinguished from applied,
+ pure logic from applied, so if we choose we may also
+ distinguish pure philosophy of morals (metaphysic) from
+ applied (viz., applied to human nature). By this designation
+ we are also at once reminded that moral principles are not
+ based on properties of human nature, but must subsist a
+ priori of themselves, while from such principles practical
+ rules must be capable of being deduced for every rational
+ nature, and accordingly for that of man.
+</pre>
+ <p>
+ Such a metaphysic of morals, completely isolated, not mixed with any
+ anthropology, theology, physics, or hyperphysics, and still less with
+ occult qualities (which we might call hypophysical), is not only an
+ indispensable substratum of all sound theoretical knowledge of duties, but
+ is at the same time a desideratum of the highest importance to the actual
+ fulfilment of their precepts. For the pure conception of duty, unmixed
+ with any foreign addition of empirical attractions, and, in a word, the
+ conception of the moral law, exercises on the human heart, by way of
+ reason alone (which first becomes aware with this that it can of itself be
+ practical), an influence so much more powerful than all other springs *
+ which may be derived from the field of experience, that, in the
+ consciousness of its worth, it despises the latter, and can by degrees
+ become their master; whereas a mixed ethics, compounded partly of motives
+ drawn from feelings and inclinations, and partly also of conceptions of
+ reason, must make the mind waver between motives which cannot be brought
+ under any principle, which lead to good only by mere accident and very
+ often also to evil.
+ </p>
+<pre xml:space="preserve">
+ * I have a letter from the late excellent Sulzer, in which
+ he asks me what can be the reason that moral instruction,
+ although containing much that is convincing for the reason,
+ yet accomplishes so little? My answer was postponed in order
+ that I might make it complete. But it is simply this: that
+ the teachers themselves have not got their own notions
+ clear, and when they endeavour to make up for this by raking
+ up motives of moral goodness from every quarter, trying to
+ make their physic right strong, they spoil it. For the
+ commonest understanding shows that if we imagine, on the one
+ hand, an act of honesty done with steadfast mind, apart from
+ every view to advantage of any kind in this world or
+ another, and even under the greatest temptations of
+ necessity or allurement, and, on the other hand, a similar
+ act which was affected, in however low a degree, by a
+ foreign motive, the former leaves far behind and eclipses
+ the second; it elevates the soul and inspires the wish to be
+ able to act in like manner oneself. Even moderately young
+ children feel this impression, ana one should never
+ represent duties to them in any other light.
+</pre>
+ <p>
+ From what has been said, it is clear that all moral conceptions have their
+ seat and origin completely a priori in the reason, and that, moreover, in
+ the commonest reason just as truly as in that which is in the highest
+ degree speculative; that they cannot be obtained by abstraction from any
+ empirical, and therefore merely contingent, knowledge; that it is just
+ this purity of their origin that makes them worthy to serve as our supreme
+ practical principle, and that just in proportion as we add anything
+ empirical, we detract from their genuine influence and from the absolute
+ value of actions; that it is not only of the greatest necessity, in a
+ purely speculative point of view, but is also of the greatest practical
+ importance, to derive these notions and laws from pure reason, to present
+ them pure and unmixed, and even to determine the compass of this practical
+ or pure rational knowledge, i.e., to determine the whole faculty of pure
+ practical reason; and, in doing so, we must not make its principles
+ dependent on the particular nature of human reason, though in speculative
+ philosophy this may be permitted, or may even at times be necessary; but
+ since moral laws ought to hold good for every rational creature, we must
+ derive them from the general concept of a rational being. In this way,
+ although for its application to man morality has need of anthropology,
+ yet, in the first instance, we must treat it independently as pure
+ philosophy, i.e., as metaphysic, complete in itself (a thing which in such
+ distinct branches of science is easily done); knowing well that unless we
+ are in possession of this, it would not only be vain to determine the
+ moral element of duty in right actions for purposes of speculative
+ criticism, but it would be impossible to base morals on their genuine
+ principles, even for common practical purposes, especially of moral
+ instruction, so as to produce pure moral dispositions, and to engraft them
+ on men's minds to the promotion of the greatest possible good in the
+ world.
+ </p>
+ <p>
+ But in order that in this study we may not merely advance by the natural
+ steps from the common moral judgement (in this case very worthy of
+ respect) to the philosophical, as has been already done, but also from a
+ popular philosophy, which goes no further than it can reach by groping
+ with the help of examples, to metaphysic (which does allow itself to be
+ checked by anything empirical and, as it must measure the whole extent of
+ this kind of rational knowledge, goes as far as ideal conceptions, where
+ even examples fail us), we must follow and clearly describe the practical
+ faculty of reason, from the general rules of its determination to the
+ point where the notion of duty springs from it.
+ </p>
+ <p>
+ Everything in nature works according to laws. Rational beings alone have
+ the faculty of acting according to the conception of laws, that is
+ according to principles, i.e., have a will. Since the deduction of actions
+ from principles requires reason, the will is nothing but practical reason.
+ If reason infallibly determines the will, then the actions of such a being
+ which are recognised as objectively necessary are subjectively necessary
+ also, i.e., the will is a faculty to choose that only which reason
+ independent of inclination recognises as practically necessary, i.e., as
+ good. But if reason of itself does not sufficiently determine the will, if
+ the latter is subject also to subjective conditions (particular impulses)
+ which do not always coincide with the objective conditions; in a word, if
+ the will does not in itself completely accord with reason (which is
+ actually the case with men), then the actions which objectively are
+ recognised as necessary are subjectively contingent, and the determination
+ of such a will according to objective laws is obligation, that is to say,
+ the relation of the objective laws to a will that is not thoroughly good
+ is conceived as the determination of the will of a rational being by
+ principles of reason, but which the will from its nature does not of
+ necessity follow.
+ </p>
+ <p>
+ The conception of an objective principle, in so far as it is obligatory
+ for a will, is called a command (of reason), and the formula of the
+ command is called an imperative.
+ </p>
+ <p>
+ All imperatives are expressed by the word ought [or shall], and thereby
+ indicate the relation of an objective law of reason to a will, which from
+ its subjective constitution is not necessarily determined by it (an
+ obligation). They say that something would be good to do or to forbear,
+ but they say it to a will which does not always do a thing because it is
+ conceived to be good to do it. That is practically good, however, which
+ determines the will by means of the conceptions of reason, and
+ consequently not from subjective causes, but objectively, that is on
+ principles which are valid for every rational being as such. It is
+ distinguished from the pleasant, as that which influences the will only by
+ means of sensation from merely subjective causes, valid only for the sense
+ of this or that one, and not as a principle of reason, which holds for
+ every one. *
+ </p>
+<pre xml:space="preserve">
+ * The dependence of the desires on sensations is called
+ inclination, and this accordingly always indicates a want.
+ The dependence of a contingently determinable will on
+ principles of reason is called an interest. This therefore,
+ is found only in the case of a dependent will which does not
+ always of itself conform to reason; in the Divine will we
+ cannot conceive any interest. But the human will can also
+ take an interest in a thing without therefore acting from
+ interest. The former signifies the practical interest in the
+ action, the latter the pathological in the object of the
+ action. The former indicates only dependence of the will on
+ principles of reason in themselves; the second, dependence
+ on principles of reason for the sake of inclination, reason
+ supplying only the practical rules how the requirement of
+ the inclination may be satisfied. In the first case the
+ action interests me; in the second the object of the action
+ (because it is pleasant to me). We have seen in the first
+ section that in an action done from duty we must look not to
+ the interest in the object, but only to that in the action
+ itself, and in its rational principle (viz., the law).
+</pre>
+ <p>
+ A perfectly good will would therefore be equally subject to objective laws
+ (viz., laws of good), but could not be conceived as obliged thereby to act
+ lawfully, because of itself from its subjective constitution it can only
+ be determined by the conception of good. Therefore no imperatives hold for
+ the Divine will, or in general for a holy will; ought is here out of
+ place, because the volition is already of itself necessarily in unison
+ with the law. Therefore imperatives are only formulae to express the
+ relation of objective laws of all volition to the subjective imperfection
+ of the will of this or that rational being, e.g., the human will.
+ </p>
+ <p>
+ Now all imperatives command either hypothetically or categorically. The
+ former represent the practical necessity of a possible action as means to
+ something else that is willed (or at least which one might possibly will).
+ The categorical imperative would be that which represented an action as
+ necessary of itself without reference to another end, i.e., as objectively
+ necessary.
+ </p>
+ <p>
+ Since every practical law represents a possible action as good and, on
+ this account, for a subject who is practically determinable by reason,
+ necessary, all imperatives are formulae determining an action which is
+ necessary according to the principle of a will good in some respects. If
+ now the action is good only as a means to something else, then the
+ imperative is hypothetical; if it is conceived as good in itself and
+ consequently as being necessarily the principle of a will which of itself
+ conforms to reason, then it is categorical.
+ </p>
+ <p>
+ Thus the imperative declares what action possible by me would be good and
+ presents the practical rule in relation to a will which does not forthwith
+ perform an action simply because it is good, whether because the subject
+ does not always know that it is good, or because, even if it know this,
+ yet its maxims might be opposed to the objective principles of practical
+ reason.
+ </p>
+ <p>
+ Accordingly the hypothetical imperative only says that the action is good
+ for some purpose, possible or actual. In the first case it is a
+ problematical, in the second an assertorial practical principle. The
+ categorical imperative which declares an action to be objectively
+ necessary in itself without reference to any purpose, i.e., without any
+ other end, is valid as an apodeictic (practical) principle.
+ </p>
+ <p>
+ Whatever is possible only by the power of some rational being may also be
+ conceived as a possible purpose of some will; and therefore the principles
+ of action as regards the means necessary to attain some possible purpose
+ are in fact infinitely numerous. All sciences have a practical part,
+ consisting of problems expressing that some end is possible for us and of
+ imperatives directing how it may be attained. These may, therefore, be
+ called in general imperatives of skill. Here there is no question whether
+ the end is rational and good, but only what one must do in order to attain
+ it. The precepts for the physician to make his patient thoroughly healthy,
+ and for a poisoner to ensure certain death, are of equal value in this
+ respect, that each serves to effect its purpose perfectly. Since in early
+ youth it cannot be known what ends are likely to occur to us in the course
+ of life, parents seek to have their children taught a great many things,
+ and provide for their skill in the use of means for all sorts of arbitrary
+ ends, of none of which can they determine whether it may not perhaps
+ hereafter be an object to their pupil, but which it is at all events
+ possible that he might aim at; and this anxiety is so great that they
+ commonly neglect to form and correct their judgement on the value of the
+ things which may be chosen as ends.
+ </p>
+ <p>
+ There is one end, however, which may be assumed to be actually such to all
+ rational beings (so far as imperatives apply to them, viz., as dependent
+ beings), and, therefore, one purpose which they not merely may have, but
+ which we may with certainty assume that they all actually have by a
+ natural necessity, and this is happiness. The hypothetical imperative
+ which expresses the practical necessity of an action as means to the
+ advancement of happiness is assertorial. We are not to present it as
+ necessary for an uncertain and merely possible purpose, but for a purpose
+ which we may presuppose with certainty and a priori in every man, because
+ it belongs to his being. Now skill in the choice of means to his own
+ greatest well-being may be called prudence, * in the narrowest sense. And
+ thus the imperative which refers to the choice of means to one's own
+ happiness, i.e., the precept of prudence, is still always hypothetical;
+ the action is not commanded absolutely, but only as means to another
+ purpose.
+ </p>
+<pre xml:space="preserve">
+ * The word prudence is taken in two senses: in the one it
+ may bear the name of knowledge of the world, in the other
+ that of private prudence. The former is a man's ability to
+ influence others so as to use them for his own purposes. The
+ latter is the sagacity to combine all these purposes for his
+ own lasting benefit. This latter is properly that to which
+ the value even of the former is reduced, and when a man is
+ prudent in the former sense, but not in the latter, we might
+ better say of him that he is clever and cunning, but, on the
+ whole, imprudent.
+</pre>
+ <p>
+ Finally, there is an imperative which commands a certain conduct
+ immediately, without having as its condition any other purpose to be
+ attained by it. This imperative is categorical. It concerns not the matter
+ of the action, or its intended result, but its form and the principle of
+ which it is itself a result; and what is essentially good in it consists
+ in the mental disposition, let the consequence be what it may. This
+ imperative may be called that of morality.
+ </p>
+ <p>
+ There is a marked distinction also between the volitions on these three
+ sorts of principles in the dissimilarity of the obligation of the will. In
+ order to mark this difference more clearly, I think they would be most
+ suitably named in their order if we said they are either rules of skill,
+ or counsels of prudence, or commands (laws) of morality. For it is law
+ only that involves the conception of an unconditional and objective
+ necessity, which is consequently universally valid; and commands are laws
+ which must be obeyed, that is, must be followed, even in opposition to
+ inclination. Counsels, indeed, involve necessity, but one which can only
+ hold under a contingent subjective condition, viz., they depend on whether
+ this or that man reckons this or that as part of his happiness; the
+ categorical imperative, on the contrary, is not limited by any condition,
+ and as being absolutely, although practically, necessary, may be quite
+ properly called a command. We might also call the first kind of
+ imperatives technical (belonging to art), the second pragmatic * (to
+ welfare), the third moral (belonging to free conduct generally, that is,
+ to morals).
+ </p>
+<pre xml:space="preserve">
+ * It seems to me that the proper signification of the word
+ pragmatic may be most accurately defined in this way. For
+ sanctions are called pragmatic which flow properly not from
+ the law of the states as necessary enactments, but from
+ precaution for the general welfare. A history is composed
+ pragmatically when it teaches prudence, i.e., instructs the
+ world how it can provide for its interests better, or at
+ least as well as, the men of former time.
+</pre>
+ <p>
+ Now arises the question, how are all these imperatives possible? This
+ question does not seek to know how we can conceive the accomplishment of
+ the action which the imperative ordains, but merely how we can conceive
+ the obligation of the will which the imperative expresses. No special
+ explanation is needed to show how an imperative of skill is possible.
+ Whoever wills the end, wills also (so far as reason decides his conduct)
+ the means in his power which are indispensably necessary thereto. This
+ proposition is, as regards the volition, analytical; for, in willing an
+ object as my effect, there is already thought the causality of myself as
+ an acting cause, that is to say, the use of the means; and the imperative
+ educes from the conception of volition of an end the conception of actions
+ necessary to this end. Synthetical propositions must no doubt be employed
+ in defining the means to a proposed end; but they do not concern the
+ principle, the act of the will, but the object and its realization. E.g.,
+ that in order to bisect a line on an unerring principle I must draw from
+ its extremities two intersecting arcs; this no doubt is taught by
+ mathematics only in synthetical propositions; but if I know that it is
+ only by this process that the intended operation can be performed, then to
+ say that, if I fully will the operation, I also will the action required
+ for it, is an analytical proposition; for it is one and the same thing to
+ conceive something as an effect which I can produce in a certain way, and
+ to conceive myself as acting in this way.
+ </p>
+ <p>
+ If it were only equally easy to give a definite conception of happiness,
+ the imperatives of prudence would correspond exactly with those of skill,
+ and would likewise be analytical. For in this case as in that, it could be
+ said: "Whoever wills the end, wills also (according to the dictate of
+ reason necessarily) the indispensable means thereto which are in his
+ power." But, unfortunately, the notion of happiness is so indefinite that
+ although every man wishes to attain it, yet he never can say definitely
+ and consistently what it is that he really wishes and wills. The reason of
+ this is that all the elements which belong to the notion of happiness are
+ altogether empirical, i.e., they must be borrowed from experience, and
+ nevertheless the idea of happiness requires an absolute whole, a maximum
+ of welfare in my present and all future circumstances. Now it is
+ impossible that the most clear-sighted and at the same time most powerful
+ being (supposed finite) should frame to himself a definite conception of
+ what he really wills in this. Does he will riches, how much anxiety, envy,
+ and snares might he not thereby draw upon his shoulders? Does he will
+ knowledge and discernment, perhaps it might prove to be only an eye so
+ much the sharper to show him so much the more fearfully the evils that are
+ now concealed from him, and that cannot be avoided, or to impose more
+ wants on his desires, which already give him concern enough. Would he have
+ long life? who guarantees to him that it would not be a long misery? would
+ he at least have health? how often has uneasiness of the body restrained
+ from excesses into which perfect health would have allowed one to fall?
+ and so on. In short, he is unable, on any principle, to determine with
+ certainty what would make him truly happy; because to do so he would need
+ to be omniscient. We cannot therefore act on any definite principles to
+ secure happiness, but only on empirical counsels, e.g. of regimen,
+ frugality, courtesy, reserve, etc., which experience teaches do, on the
+ average, most promote well-being. Hence it follows that the imperatives of
+ prudence do not, strictly speaking, command at all, that is, they cannot
+ present actions objectively as practically necessary; that they are rather
+ to be regarded as counsels (consilia) than precepts precepts of reason,
+ that the problem to determine certainly and universally what action would
+ promote the happiness of a rational being is completely insoluble, and
+ consequently no imperative respecting it is possible which should, in the
+ strict sense, command to do what makes happy; because happiness is not an
+ ideal of reason but of imagination, resting solely on empirical grounds,
+ and it is vain to expect that these should define an action by which one
+ could attain the totality of a series of consequences which is really
+ endless. This imperative of prudence would however be an analytical
+ proposition if we assume that the means to happiness could be certainly
+ assigned; for it is distinguished from the imperative of skill only by
+ this, that in the latter the end is merely possible, in the former it is
+ given; as however both only ordain the means to that which we suppose to
+ be willed as an end, it follows that the imperative which ordains the
+ willing of the means to him who wills the end is in both cases analytical.
+ Thus there is no difficulty in regard to the possibility of an imperative
+ of this kind either.
+ </p>
+ <p>
+ On the other hand, the question how the imperative of morality is
+ possible, is undoubtedly one, the only one, demanding a solution, as this
+ is not at all hypothetical, and the objective necessity which it presents
+ cannot rest on any hypothesis, as is the case with the hypothetical
+ imperatives. Only here we must never leave out of consideration that we
+ cannot make out by any example, in other words empirically, whether there
+ is such an imperative at all, but it is rather to be feared that all those
+ which seem to be categorical may yet be at bottom hypothetical. For
+ instance, when the precept is: "Thou shalt not promise deceitfully"; and
+ it is assumed that the necessity of this is not a mere counsel to avoid
+ some other evil, so that it should mean: "Thou shalt not make a lying
+ promise, lest if it become known thou shouldst destroy thy credit," but
+ that an action of this kind must be regarded as evil in itself, so that
+ the imperative of the prohibition is categorical; then we cannot show with
+ certainty in any example that the will was determined merely by the law,
+ without any other spring of action, although it may appear to be so. For
+ it is always possible that fear of disgrace, perhaps also obscure dread of
+ other dangers, may have a secret influence on the will. Who can prove by
+ experience the non-existence of a cause when all that experience tells us
+ is that we do not perceive it? But in such a case the so-called moral
+ imperative, which as such appears to be categorical and unconditional,
+ would in reality be only a pragmatic precept, drawing our attention to our
+ own interests and merely teaching us to take these into consideration.
+ </p>
+ <p>
+ We shall therefore have to investigate a priori the possibility of a
+ categorical imperative, as we have not in this case the advantage of its
+ reality being given in experience, so that [the elucidation of] its
+ possibility should be requisite only for its explanation, not for its
+ establishment. In the meantime it may be discerned beforehand that the
+ categorical imperative alone has the purport of a practical law; all the
+ rest may indeed be called principles of the will but not laws, since
+ whatever is only necessary for the attainment of some arbitrary purpose
+ may be considered as in itself contingent, and we can at any time be free
+ from the precept if we give up the purpose; on the contrary, the
+ unconditional command leaves the will no liberty to choose the opposite;
+ consequently it alone carries with it that necessity which we require in a
+ law.
+ </p>
+ <p>
+ Secondly, in the case of this categorical imperative or law of morality,
+ the difficulty (of discerning its possibility) is a very profound one. It
+ is an a priori synthetical practical proposition; * and as there is so
+ much difficulty in discerning the possibility of speculative propositions
+ of this kind, it may readily be supposed that the difficulty will be no
+ less with the practical.
+ </p>
+<pre xml:space="preserve">
+ * I connect the act with the will without presupposing any
+ condition resulting from any inclination, but a priori, and
+ therefore necessarily (though only objectively, i.e.,
+ assuming the idea of a reason possessing full power over all
+ subjective motives). This is accordingly a practical
+ proposition which does not deduce the willing of an action
+ by mere analysis from another already presupposed (for we
+ have not such a perfect will), but connects it immediately
+ with the conception of the will of a rational being, as
+ something not contained in it.
+</pre>
+ <p>
+ In this problem we will first inquire whether the mere conception of a
+ categorical imperative may not perhaps supply us also with the formula of
+ it, containing the proposition which alone can be a categorical
+ imperative; for even if we know the tenor of such an absolute command, yet
+ how it is possible will require further special and laborious study, which
+ we postpone to the last section.
+ </p>
+ <p>
+ When I conceive a hypothetical imperative, in general I do not know
+ beforehand what it will contain until I am given the condition. But when I
+ conceive a categorical imperative, I know at once what it contains. For as
+ the imperative contains besides the law only the necessity that the maxims
+ * shall conform to this law, while the law contains no conditions
+ restricting it, there remains nothing but the general statement that the
+ maxim of the action should conform to a universal law, and it is this
+ conformity alone that the imperative properly represents as necessary.
+ </p>
+<pre xml:space="preserve">
+ * A maxim is a subjective principle of action, and must be
+ distinguished from the objective principle, namely,
+ practical law. The former contains the practical rule set by
+ reason according to the conditions of the subject (often its
+ ignorance or its inclinations), so that it is the principle
+ on which the subject acts; but the law is the objective
+ principle valid for every rational being, and is the
+ principle on which it ought to act that is an imperative.
+</pre>
+ <p>
+ There is therefore but one categorical imperative, namely, this: Act only
+ on that maxim whereby thou canst at the same time will that it should
+ become a universal law.
+ </p>
+ <p>
+ Now if all imperatives of duty can be deduced from this one imperative as
+ from their principle, then, although it should remain undecided what is
+ called duty is not merely a vain notion, yet at least we shall be able to
+ show what we understand by it and what this notion means.
+ </p>
+ <p>
+ Since the universality of the law according to which effects are produced
+ constitutes what is properly called nature in the most general sense (as
+ to form), that is the existence of things so far as it is determined by
+ general laws, the imperative of duty may be expressed thus: Act as if the
+ maxim of thy action were to become by thy will a universal law of nature.
+ </p>
+ <p>
+ We will now enumerate a few duties, adopting the usual division of them
+ into duties to ourselves and ourselves and to others, and into perfect and
+ imperfect duties. *
+ </p>
+<pre xml:space="preserve">
+ * It must be noted here that I reserve the division of
+ duties for a future metaphysic of morals; so that I give it
+ here only as an arbitrary one (in order to arrange my
+ examples). For the rest, I understand by a perfect duty one
+ that admits no exception in favour of inclination and then I
+ have not merely external but also internal perfect duties.
+ This is contrary to the use of the word adopted in the
+ schools; but I do not intend to justify there, as it is all
+ one for my purpose whether it is admitted or not.
+</pre>
+ <p>
+ 1. A man reduced to despair by a series of misfortunes feels wearied of
+ life, but is still so far in possession of his reason that he can ask
+ himself whether it would not be contrary to his duty to himself to take
+ his own life. Now he inquires whether the maxim of his action could become
+ a universal law of nature. His maxim is: "From self-love I adopt it as a
+ principle to shorten my life when its longer duration is likely to bring
+ more evil than satisfaction." It is asked then simply whether this
+ principle founded on self-love can become a universal law of nature. Now
+ we see at once that a system of nature of which it should be a law to
+ destroy life by means of the very feeling whose special nature it is to
+ impel to the improvement of life would contradict itself and, therefore,
+ could not exist as a system of nature; hence that maxim cannot possibly
+ exist as a universal law of nature and, consequently, would be wholly
+ inconsistent with the supreme principle of all duty.
+ </p>
+ <p>
+ 2. Another finds himself forced by necessity to borrow money. He knows
+ that he will not be able to repay it, but sees also that nothing will be
+ lent to him unless he promises stoutly to repay it in a definite time. He
+ desires to make this promise, but he has still so much conscience as to
+ ask himself: "Is it not unlawful and inconsistent with duty to get out of
+ a difficulty in this way?" Suppose however that he resolves to do so: then
+ the maxim of his action would be expressed thus: "When I think myself in
+ want of money, I will borrow money and promise to repay it, although I
+ know that I never can do so." Now this principle of self-love or of one's
+ own advantage may perhaps be consistent with my whole future welfare; but
+ the question now is, "Is it right?" I change then the suggestion of
+ self-love into a universal law, and state the question thus: "How would it
+ be if my maxim were a universal law?" Then I see at once that it could
+ never hold as a universal law of nature, but would necessarily contradict
+ itself. For supposing it to be a universal law that everyone when he
+ thinks himself in a difficulty should be able to promise whatever he
+ pleases, with the purpose of not keeping his promise, the promise itself
+ would become impossible, as well as the end that one might have in view in
+ it, since no one would consider that anything was promised to him, but
+ would ridicule all such statements as vain pretences.

+ 3. A third finds in himself a talent which with the help of some culture
+ might make him a useful man in many respects. But he finds himself in
+ comfortable circumstances and prefers to indulge in pleasure rather than
+ to take pains in enlarging and improving his happy natural capacities. He
+ asks, however, whether his maxim of neglect of his natural gifts, besides
+ agreeing with his inclination to indulgence, agrees also with what is
+ called duty. He sees then that a system of nature could indeed subsist
+ with such a universal law although men (like the South Sea islanders)
+ should let their talents rest and resolve to devote their lives merely to
+ idleness, amusement, and propagation of their species- in a word, to
+ enjoyment; but he cannot possibly will that this should be a universal law
+ of nature, or be implanted in us as such by a natural instinct. For, as a
+ rational being, he necessarily wills that his faculties be developed,
+ since they serve him and have been given him, for all sorts of possible
+ purposes.
+ </p>
+ <p>
+ 4. A fourth, who is in prosperity, while he sees that others have to
+ contend with great wretchedness and that he could help them, thinks: "What
+ concern is it of mine? Let everyone be as happy as Heaven pleases, or as
+ he can make himself; I will take nothing from him nor even envy him, only
+ I do not wish to contribute anything to his welfare or to his assistance
+ in distress!" Now no doubt if such a mode of thinking were a universal
+ law, the human race might very well subsist and doubtless even better than
+ in a state in which everyone talks of sympathy and good-will, or even
+ takes care occasionally to put it into practice, but, on the other side,
+ also cheats when he can, betrays the rights of men, or otherwise violates
+ them. But although it is possible that a universal law of nature might
+ exist in accordance with that maxim, it is impossible to will that such a
+ principle should have the universal validity of a law of nature. For a
+ will which resolved this would contradict itself, inasmuch as many cases
+ might occur in which one would have need of the love and sympathy of
+ others, and in which, by such a law of nature, sprung from his own will,
+ he would deprive himself of all hope of the aid he desires.
+ </p>
+ <p>
+ These are a few of the many actual duties, or at least what we regard as
+ such, which obviously fall into two classes on the one principle that we
+ have laid down. We must be able to will that a maxim of our action should
+ be a universal law. This is the canon of the moral appreciation of the
+ action generally. Some actions are of such a character that their maxim
+ cannot without contradiction be even conceived as a universal law of
+ nature, far from it being possible that we should will that it should be
+ so. In others this intrinsic impossibility is not found, but still it is
+ impossible to will that their maxim should be raised to the universality
+ of a law of nature, since such a will would contradict itself It is easily
+ seen that the former violate strict or rigorous (inflexible) duty; the
+ latter only laxer (meritorious) duty. Thus it has been completely shown
+ how all duties depend as regards the nature of the obligation (not the
+ object of the action) on the same principle.
+ </p>
+ <p>
+ If now we attend to ourselves on occasion of any transgression of duty, we
+ shall find that we in fact do not will that our maxim should be a
+ universal law, for that is impossible for us; on the contrary, we will
+ that the opposite should remain a universal law, only we assume the
+ liberty of making an exception in our own favour or (just for this time
+ only) in favour of our inclination. Consequently if we considered all
+ cases from one and the same point of view, namely, that of reason, we
+ should find a contradiction in our own will, namely, that a certain
+ principle should be objectively necessary as a universal law, and yet
+ subjectively should not be universal, but admit of exceptions. As however
+ we at one moment regard our action from the point of view of a will wholly
+ conformed to reason, and then again look at the same action from the point
+ of view of a will affected by inclination, there is not really any
+ contradiction, but an antagonism of inclination to the precept of reason,
+ whereby the universality of the principle is changed into a mere
+ generality, so that the practical principle of reason shall meet the maxim
+ half way. Now, although this cannot be justified in our own impartial
+ judgement, yet it proves that we do really recognise the validity of the
+ categorical imperative and (with all respect for it) only allow ourselves
+ a few exceptions, which we think unimportant and forced from us.
+ </p>
+ <p>
+ We have thus established at least this much, that if duty is a conception
+ which is to have any import and real legislative authority for our
+ actions, it can only be expressed in categorical and not at all in
+ hypothetical imperatives. We have also, which is of great importance,
+ exhibited clearly and definitely for every practical application the
+ content of the categorical imperative, which must contain the principle of
+ all duty if there is such a thing at all. We have not yet, however,
+ advanced so far as to prove a priori that there actually is such an
+ imperative, that there is a practical law which commands absolutely of
+ itself and without any other impulse, and that the following of this law
+ is duty.
+ </p>
+ <p>
+ With the view of attaining to this, it is of extreme importance to
+ remember that we must not allow ourselves to think of deducing the reality
+ of this principle from the particular attributes of human nature. For duty
+ is to be a practical, unconditional necessity of action; it must therefore
+ hold for all rational beings (to whom an imperative can apply at all), and
+ for this reason only be also a law for all human wills. On the contrary,
+ whatever is deduced from the particular natural characteristics of
+ humanity, from certain feelings and propensions, nay, even, if possible,
+ from any particular tendency proper to human reason, and which need not
+ necessarily hold for the will of every rational being; this may indeed
+ supply us with a maxim, but not with a law; with a subjective principle on
+ which we may have a propension and inclination to act, but not with an
+ objective principle on which we should be enjoined to act, even though all
+ our propensions, inclinations, and natural dispositions were opposed to
+ it. In fact, the sublimity and intrinsic dignity of the command in duty
+ are so much the more evident, the less the subjective impulses favour it
+ and the more they oppose it, without being able in the slightest degree to
+ weaken the obligation of the law or to diminish its validity.
+ </p>
+ <p>
+ Here then we see philosophy brought to a critical position, since it has
+ to be firmly fixed, notwithstanding that it has nothing to support it in
+ heaven or earth. Here it must show its purity as absolute director of its
+ own laws, not the herald of those which are whispered to it by an
+ implanted sense or who knows what tutelary nature. Although these may be
+ better than nothing, yet they can never afford principles dictated by
+ reason, which must have their source wholly a priori and thence their
+ commanding authority, expecting everything from the supremacy of the law
+ and the due respect for it, nothing from inclination, or else condemning
+ the man to self-contempt and inward abhorrence.
+ </p>
+ <p>
+ Thus every empirical element is not only quite incapable of being an aid
+ to the principle of morality, but is even highly prejudicial to the purity
+ of morals, for the proper and inestimable worth of an absolutely good will
+ consists just in this, that the principle of action is free from all
+ influence of contingent grounds, which alone experience can furnish. We
+ cannot too much or too often repeat our warning against this lax and even
+ mean habit of thought which seeks for its principle amongst empirical
+ motives and laws; for human reason in its weariness is glad to rest on
+ this pillow, and in a dream of sweet illusions (in which, instead of Juno,
+ it embraces a cloud) it substitutes for morality a bastard patched up from
+ limbs of various derivation, which looks like anything one chooses to see
+ in it, only not like virtue to one who has once beheld her in her true
+ form. *
+ </p>
+<pre xml:space="preserve">
+ * To behold virtue in her proper form is nothing else but to
+ contemplate morality stripped of all admixture of sensible
+ things and of every spurious ornament of reward or self-
+ love. How much she then eclipses everything else that
+ appears charming to the affections, every one may readily
+ perceive with the least exertion of his reason, if it be not
+ wholly spoiled for abstraction.
+</pre>
+ <p>
+ The question then is this: "Is it a necessary law for all rational beings
+ that they should always judge of their actions by maxims of which they can
+ themselves will that they should serve as universal laws?" If it is so,
+ then it must be connected (altogether a priori) with the very conception
+ of the will of a rational being generally. But in order to discover this
+ connexion we must, however reluctantly, take a step into metaphysic,
+ although into a domain of it which is distinct from speculative
+ philosophy, namely, the metaphysic of morals. In a practical philosophy,
+ where it is not the reasons of what happens that we have to ascertain, but
+ the laws of what ought to happen, even although it never does, i.e.,
+ objective practical laws, there it is not necessary to inquire into the
+ reasons why anything pleases or displeases, how the pleasure of mere
+ sensation differs from taste, and whether the latter is distinct from a
+ general satisfaction of reason; on what the feeling of pleasure or pain
+ rests, and how from it desires and inclinations arise, and from these
+ again maxims by the co-operation of reason: for all this belongs to an
+ empirical psychology, which would constitute the second part of physics,
+ if we regard physics as the philosophy of nature, so far as it is based on
+ empirical laws. But here we are concerned with objective practical laws
+ and, consequently, with the relation of the will to itself so far as it is
+ determined by reason alone, in which case whatever has reference to
+ anything empirical is necessarily excluded; since if reason of itself
+ alone determines the conduct (and it is the possibility of this that we
+ are now investigating), it must necessarily do so a priori.
+ </p>
+ <p>
+ The will is conceived as a faculty of determining oneself to action in
+ accordance with the conception of certain laws. And such a faculty can be
+ found only in rational beings. Now that which serves the will as the
+ objective ground of its self-determination is the end, and, if this is
+ assigned by reason alone, it must hold for all rational beings. On the
+ other hand, that which merely contains the ground of possibility of the
+ action of which the effect is the end, this is called the means. The
+ subjective ground of the desire is the spring, the objective ground of the
+ volition is the motive; hence the distinction between subjective ends
+ which rest on springs, and objective ends which depend on motives valid
+ for every rational being. Practical principles are formal when they
+ abstract from all subjective ends; they are material when they assume
+ these, and therefore particular springs of action. The ends which a
+ rational being proposes to himself at pleasure as effects of his actions
+ (material ends) are all only relative, for it is only their relation to
+ the particular desires of the subject that gives them their worth, which
+ therefore cannot furnish principles universal and necessary for all
+ rational beings and for every volition, that is to say practical laws.
+ Hence all these relative ends can give rise only to hypothetical
+ imperatives.
+ </p>
+ <p>
+ Supposing, however, that there were something whose existence has in
+ itself an absolute worth, something which, being an end in itself, could
+ be a source of definite laws; then in this and this alone would lie the
+ source of a possible categorical imperative, i.e., a practical law.
+ </p>
+ <p>
+ Now I say: man and generally any rational being exists as an end in
+ himself, not merely as a means to be arbitrarily used by this or that
+ will, but in all his actions, whether they concern himself or other
+ rational beings, must be always regarded at the same time as an end. All
+ objects of the inclinations have only a conditional worth, for if the
+ inclinations and the wants founded on them did not exist, then their
+ object would be without value. But the inclinations, themselves being
+ sources of want, are so far from having an absolute worth for which they
+ should be desired that on the contrary it must be the universal wish of
+ every rational being to be wholly free from them. Thus the worth of any
+ object which is to be acquired by our action is always conditional. Beings
+ whose existence depends not on our will but on nature's, have
+ nevertheless, if they are irrational beings, only a relative value as
+ means, and are therefore called things; rational beings, on the contrary,
+ are called persons, because their very nature points them out as ends in
+ themselves, that is as something which must not be used merely as means,
+ and so far therefore restricts freedom of action (and is an object of
+ respect). These, therefore, are not merely subjective ends whose existence
+ has a worth for us as an effect of our action, but objective ends, that
+ is, things whose existence is an end in itself; an end moreover for which
+ no other can be substituted, which they should subserve merely as means,
+ for otherwise nothing whatever would possess absolute worth; but if all
+ worth were conditioned and therefore contingent, then there would be no
+ supreme practical principle of reason whatever.
+ </p>
+ <p>
+ If then there is a supreme practical principle or, in respect of the human
+ will, a categorical imperative, it must be one which, being drawn from the
+ conception of that which is necessarily an end for everyone because it is
+ an end in itself, constitutes an objective principle of will, and can
+ therefore serve as a universal practical law. The foundation of this
+ principle is: rational nature exists as an end in itself. Man necessarily
+ conceives his own existence as being so; so far then this is a subjective
+ principle of human actions. But every other rational being regards its
+ existence similarly, just on the same rational principle that holds for
+ me: * so that it is at the same time an objective principle, from which as
+ a supreme practical law all laws of the will must be capable of being
+ deduced. Accordingly the practical imperative will be as follows: So act
+ as to treat humanity, whether in thine own person or in that of any other,
+ in every case as an end withal, never as means only. We will now inquire
+ whether this can be practically carried out.
+ </p>
+<pre xml:space="preserve">
+ * This proposition is here stated as a postulate. The ground
+ of it will be found in the concluding section.
+</pre>
+ <p>
+ To abide by the previous examples:
+ </p>
+ <p>
+ Firstly, under the head of necessary duty to oneself: He who contemplates
+ suicide should ask himself whether his action can be consistent with the
+ idea of humanity as an end in itself. If he destroys himself in order to
+ escape from painful circumstances, he uses a person merely as a mean to
+ maintain a tolerable condition up to the end of life. But a man is not a
+ thing, that is to say, something which can be used merely as means, but
+ must in all his actions be always considered as an end in himself. I
+ cannot, therefore, dispose in any way of a man in my own person so as to
+ mutilate him, to damage or kill him. (It belongs to ethics proper to
+ define this principle more precisely, so as to avoid all misunderstanding,
+ e. g., as to the amputation of the limbs in order to preserve myself, as
+ to exposing my life to danger with a view to preserve it, etc. This
+ question is therefore omitted here.)
+ </p>
+ <p>
+ Secondly, as regards necessary duties, or those of strict obligation,
+ towards others: He who is thinking of making a lying promise to others
+ will see at once that he would be using another man merely as a mean,
+ without the latter containing at the same time the end in himself. For he
+ whom I propose by such a promise to use for my own purposes cannot
+ possibly assent to my mode of acting towards him and, therefore, cannot
+ himself contain the end of this action. This violation of the principle of
+ humanity in other men is more obvious if we take in examples of attacks on
+ the freedom and property of others. For then it is clear that he who
+ transgresses the rights of men intends to use the person of others merely
+ as a means, without considering that as rational beings they ought always
+ to be esteemed also as ends, that is, as beings who must be capable of
+ containing in themselves the end of the very same action. *
+ </p>
+<pre xml:space="preserve">
+ * Let it not be thought that the common "quod tibi non vis
+ fieri, etc." could serve here as the rule or principle. For
+ it is only a deduction from the former, though with several
+ limitations; it cannot be a universal law, for it does not
+ contain the principle of duties to oneself, nor of the
+ duties of benevolence to others (for many a one would gladly
+ consent that others should not benefit him, provided only
+ that he might be excused from showing benevolence to them),
+ nor finally that of duties of strict obligation to one
+ another, for on this principle the criminal might argue
+ against the judge who punishes him, and so on.
+</pre>
+ <p>
+ Thirdly, as regards contingent (meritorious) duties to oneself: It is not
+ enough that the action does not violate humanity in our own person as an
+ end in itself, it must also harmonize with it. Now there are in humanity
+ capacities of greater perfection, which belong to the end that nature has
+ in view in regard to humanity in ourselves as the subject: to neglect
+ these might perhaps be consistent with the maintenance of humanity as an
+ end in itself, but not with the advancement of this end.
+ </p>
+ <p>
+ Fourthly, as regards meritorious duties towards others: The natural end
+ which all men have is their own happiness. Now humanity might indeed
+ subsist, although no one should contribute anything to the happiness of
+ others, provided he did not intentionally withdraw anything from it; but
+ after all this would only harmonize negatively not positively with
+ humanity as an end in itself, if every one does not also endeavour, as far
+ as in him lies, to forward the ends of others. For the ends of any subject
+ which is an end in himself ought as far as possible to be my ends also, if
+ that conception is to have its full effect with me.
+ </p>
+ <p>
+ This principle, that humanity and generally every rational nature is an
+ end in itself (which is the supreme limiting condition of every man's
+ freedom of action), is not borrowed from experience, firstly, because it
+ is universal, applying as it does to all rational beings whatever, and
+ experience is not capable of determining anything about them; secondly,
+ because it does not present humanity as an end to men (subjectively), that
+ is as an object which men do of themselves actually adopt as an end; but
+ as an objective end, which must as a law constitute the supreme limiting
+ condition of all our subjective ends, let them be what we will; it must
+ therefore spring from pure reason. In fact the objective principle of all
+ practical legislation lies (according to the first principle) in the rule
+ and its form of universality which makes it capable of being a law (say,
+ e. g., a law of nature); but the subjective principle is in the end; now
+ by the second principle the subject of all ends is each rational being,
+ inasmuch as it is an end in itself. Hence follows the third practical
+ principle of the will, which is the ultimate condition of its harmony with
+ universal practical reason, viz.: the idea of the will of every rational
+ being as a universally legislative will.
+ </p>
+ <p>
+ On this principle all maxims are rejected which are inconsistent with the
+ will being itself universal legislator. Thus the will is not subject
+ simply to the law, but so subject that it must be regarded as itself
+ giving the law and, on this ground only, subject to the law (of which it
+ can regard itself as the author).
+ </p>
+ <p>
+ In the previous imperatives, namely, that based on the conception of the
+ conformity of actions to general laws, as in a physical system of nature,
+ and that based on the universal prerogative of rational beings as ends in
+ themselves- these imperatives, just because they were conceived as
+ categorical, excluded from any share in their authority all admixture of
+ any interest as a spring of action; they were, however, only assumed to be
+ categorical, because such an assumption was necessary to explain the
+ conception of duty. But we could not prove independently that there are
+ practical propositions which command categorically, nor can it be proved
+ in this section; one thing, however, could be done, namely, to indicate in
+ the imperative itself, by some determinate expression, that in the case of
+ volition from duty all interest is renounced, which is the specific
+ criterion of categorical as distinguished from hypothetical imperatives.
+ This is done in the present (third) formula of the principle, namely, in
+ the idea of the will of every rational being as a universally legislating
+ will.
+ </p>
+ <p>
+ For although a will which is subject to laws may be attached to this law
+ by means of an interest, yet a will which is itself a supreme lawgiver so
+ far as it is such cannot possibly depend on any interest, since a will so
+ dependent would itself still need another law restricting the interest of
+ its self-love by the condition that it should be valid as universal law.
+ </p>
+ <p>
+ Thus the principle that every human will is a will which in all its maxims
+ gives universal laws, * provided it be otherwise justified, would be very
+ well adapted to be the categorical imperative, in this respect, namely,
+ that just because of the idea of universal legislation it is not based on
+ interest, and therefore it alone among all possible imperatives can be
+ unconditional. Or still better, converting the proposition, if there is a
+ categorical imperative (i.e., a law for the will of every rational being),
+ it can only command that everything be done from maxims of one's will
+ regarded as a will which could at the same time will that it should itself
+ give universal laws, for in that case only the practical principle and the
+ imperative which it obeys are unconditional, since they cannot be based on
+ any interest.
+ </p>
+<pre xml:space="preserve">
+ * I may be excused from adducing examples to elucidate this
+ principle, as those which have already been used to
+ elucidate the categorical imperative and its formula would
+ all serve for the like purpose here.
+</pre>
+ <p>
+ Looking back now on all previous attempts to discover the principle of
+ morality, we need not wonder why they all failed. It was seen that man was
+ bound to laws by duty, but it was not observed that the laws to which he
+ is subject are only those of his own giving, though at the same time they
+ are universal, and that he is only bound to act in conformity with his own
+ will; a will, however, which is designed by nature to give universal laws.
+ For when one has conceived man only as subject to a law (no matter what),
+ then this law required some interest, either by way of attraction or
+ constraint, since it did not originate as a law from his own will, but
+ this will was according to a law obliged by something else to act in a
+ certain manner. Now by this necessary consequence all the labour spent in
+ finding a supreme principle of duty was irrevocably lost. For men never
+ elicited duty, but only a necessity of acting from a certain interest.
+ Whether this interest was private or otherwise, in any case the imperative
+ must be conditional and could not by any means be capable of being a moral
+ command. I will therefore call this the principle of autonomy of the will,
+ in contrast with every other which I accordingly reckon as heteronomy.
+ </p>
+ <p>
+ The conception of the will of every rational being as one which must
+ consider itself as giving in all the maxims of its will universal laws, so
+ as to judge itself and its actions from this point of view- this
+ conception leads to another which depends on it and is very fruitful,
+ namely that of a kingdom of ends.
+ </p>
+ <p>
+ By a kingdom I understand the union of different rational beings in a
+ system by common laws. Now since it is by laws that ends are determined as
+ regards their universal validity, hence, if we abstract from the personal
+ differences of rational beings and likewise from all the content of their
+ private ends, we shall be able to conceive all ends combined in a
+ systematic whole (including both rational beings as ends in themselves,
+ and also the special ends which each may propose to himself), that is to
+ say, we can conceive a kingdom of ends, which on the preceding principles
+ is possible.
+ </p>
+ <p>
+ For all rational beings come under the law that each of them must treat
+ itself and all others never merely as means, but in every case at the same
+ time as ends in themselves. Hence results a systematic union of rational
+ being by common objective laws, i.e., a kingdom which may be called a
+ kingdom of ends, since what these laws have in view is just the relation
+ of these beings to one another as ends and means. It is certainly only an
+ ideal.
+ </p>
+ <p>
+ A rational being belongs as a member to the kingdom of ends when, although
+ giving universal laws in it, he is also himself subject to these laws. He
+ belongs to it as sovereign when, while giving laws, he is not subject to
+ the will of any other.
+ </p>
+ <p>
+ A rational being must always regard himself as giving laws either as
+ member or as sovereign in a kingdom of ends which is rendered possible by
+ the freedom of will. He cannot, however, maintain the latter position
+ merely by the maxims of his will, but only in case he is a completely
+ independent being without wants and with unrestricted power adequate to
+ his will.
+ </p>
+ <p>
+ Morality consists then in the reference of all action to the legislation
+ which alone can render a kingdom of ends possible. This legislation must
+ be capable of existing in every rational being and of emanating from his
+ will, so that the principle of this will is never to act on any maxim
+ which could not without contradiction be also a universal law and,
+ accordingly, always so to act that the will could at the same time regard
+ itself as giving in its maxims universal laws. If now the maxims of
+ rational beings are not by their own nature coincident with this objective
+ principle, then the necessity of acting on it is called practical
+ necessitation, i.e., duty. Duty does not apply to the sovereign in the
+ kingdom of ends, but it does to every member of it and to all in the same
+ degree.
+ </p>
+ <p>
+ The practical necessity of acting on this principle, i.e., duty, does not
+ rest at all on feelings, impulses, or inclinations, but solely on the
+ relation of rational beings to one another, a relation in which the will
+ of a rational being must always be regarded as legislative, since
+ otherwise it could not be conceived as an end in itself. Reason then
+ refers every maxim of the will, regarding it as legislating universally,
+ to every other will and also to every action towards oneself; and this not
+ on account of any other practical motive or any future advantage, but from
+ the idea of the dignity of a rational being, obeying no law but that which
+ he himself also gives.
+ </p>
+ <p>
+ In the kingdom of ends everything has either value or dignity. Whatever
+ has a value can be replaced by something else which is equivalent;
+ whatever, on the other hand, is above all value, and therefore admits of
+ no equivalent, has a dignity.
+ </p>
+ <p>
+ Whatever has reference to the general inclinations and wants of mankind
+ has a market value; whatever, without presupposing a want, corresponds to
+ a certain taste, that is to a satisfaction in the mere purposeless play of
+ our faculties, has a fancy value; but that which constitutes the condition
+ under which alone anything can be an end in itself, this has not merely a
+ relative worth, i.e., value, but an intrinsic worth, that is, dignity.
+ </p>
+ <p>
+ Now morality is the condition under which alone a rational being can be an
+ end in himself, since by this alone is it possible that he should be a
+ legislating member in the kingdom of ends. Thus morality, and humanity as
+ capable of it, is that which alone has dignity. Skill and diligence in
+ labour have a market value; wit, lively imagination, and humour, have
+ fancy value; on the other hand, fidelity to promises, benevolence from
+ principle (not from instinct), have an intrinsic worth. Neither nature nor
+ art contains anything which in default of these it could put in their
+ place, for their worth consists not in the effects which spring from them,
+ not in the use and advantage which they secure, but in the disposition of
+ mind, that is, the maxims of the will which are ready to manifest
+ themselves in such actions, even though they should not have the desired
+ effect. These actions also need no recommendation from any subjective
+ taste or sentiment, that they may be looked on with immediate favour and
+ satisfaction: they need no immediate propension or feeling for them; they
+ exhibit the will that performs them as an object of an immediate respect,
+ and nothing but reason is required to impose them on the will; not to
+ flatter it into them, which, in the case of duties, would be a
+ contradiction. This estimation therefore shows that the worth of such a
+ disposition is dignity, and places it infinitely above all value, with
+ which it cannot for a moment be brought into comparison or competition
+ without as it were violating its sanctity.
+ </p>
+ <p>
+ What then is it which justifies virtue or the morally good disposition, in
+ making such lofty claims? It is nothing less than the privilege it secures
+ to the rational being of participating in the giving of universal laws, by
+ which it qualifies him to be a member of a possible kingdom of ends, a
+ privilege to which he was already destined by his own nature as being an
+ end in himself and, on that account, legislating in the kingdom of ends;
+ free as regards all laws of physical nature, and obeying those only which
+ he himself gives, and by which his maxims can belong to a system of
+ universal law, to which at the same time he submits himself. For nothing
+ has any worth except what the law assigns it. Now the legislation itself
+ which assigns the worth of everything must for that very reason possess
+ dignity, that is an unconditional incomparable worth; and the word respect
+ alone supplies a becoming expression for the esteem which a rational being
+ must have for it. Autonomy then is the basis of the dignity of human and
+ of every rational nature.
+ </p>
+ <p>
+ The three modes of presenting the principle of morality that have been
+ adduced are at bottom only so many formulae of the very same law, and each
+ of itself involves the other two. There is, however, a difference in them,
+ but it is rather subjectively than objectively practical, intended namely
+ to bring an idea of the reason nearer to intuition (by means of a certain
+ analogy) and thereby nearer to feeling. All maxims, in fact, have:
+ </p>
+ <p>
+ 1. A form, consisting in universality; and in this view the formula of the
+ moral imperative is expressed thus, that the maxims must be so chosen as
+ if they were to serve as universal laws of nature.
+ </p>
+ <p>
+ 2. A matter, namely, an end, and here the formula says that the rational
+ being, as it is an end by its own nature and therefore an end in itself,
+ must in every maxim serve as the condition limiting all merely relative
+ and arbitrary ends.
+ </p>

+ 3. A complete characterization of all maxims by means of that formula,
+ namely, that all maxims ought by their own legislation to harmonize with a
+ possible kingdom of ends as with a kingdom of nature. * There is a
+ progress here in the order of the categories of unity of the form of the
+ will (its universality), plurality of the matter (the objects, i.e., the
+ ends), and totality of the system of these. In forming our moral judgement
+ of actions, it is better to proceed always on the strict method and start
+ from the general formula of the categorical imperative: Act according to a
+ maxim which can at the same time make itself a universal law. If, however,
+ we wish to gain an entrance for the moral law, it is very useful to bring
+ one and the same action under the three specified conceptions, and thereby
+ as far as possible to bring it nearer to intuition.
+ </p>
+<pre xml:space="preserve">
+ * Teleology considers nature as a kingdom of ends; ethics
+ regards a possible kingdom of ends as a kingdom nature. In
+ the first case, the kingdom of ends is a theoretical idea,
+ adopted to explain what actually is. In the latter it is a
+ practical idea, adopted to bring about that which is not
+ yet, but which can be realized by our conduct, namely, if it
+ conforms to this idea.
+</pre>
+ <p>
+ We can now end where we started at the beginning, namely, with the
+ conception of a will unconditionally good. That will is absolutely good
+ which cannot be evil- in other words, whose maxim, if made a universal
+ law, could never contradict itself. This principle, then, is its supreme
+ law: "Act always on such a maxim as thou canst at the same time will to be
+ a universal law"; this is the sole condition under which a will can never
+ contradict itself; and such an imperative is categorical. Since the
+ validity of the will as a universal law for possible actions is analogous
+ to the universal connexion of the existence of things by general laws,
+ which is the formal notion of nature in general, the categorical
+ imperative can also be expressed thus: Act on maxims which can at the same
+ time have for their object themselves as universal laws of nature. Such
+ then is the formula of an absolutely good will.
+ </p>
+ <p>
+ Rational nature is distinguished from the rest of nature by this, that it
+ sets before itself an end. This end would be the matter of every good
+ will. But since in the idea of a will that is absolutely good without
+ being limited by any condition (of attaining this or that end) we must
+ abstract wholly from every end to be effected (since this would make every
+ will only relatively good), it follows that in this case the end must be
+ conceived, not as an end to be effected, but as an independently existing
+ end. Consequently it is conceived only negatively, i.e., as that which we
+ must never act against and which, therefore, must never be regarded merely
+ as means, but must in every volition be esteemed as an end likewise. Now
+ this end can be nothing but the subject of all possible ends, since this
+ is also the subject of a possible absolutely good will; for such a will
+ cannot without contradiction be postponed to any other object. The
+ principle: "So act in regard to every rational being (thyself and others),
+ that he may always have place in thy maxim as an end in himself," is
+ accordingly essentially identical with this other: "Act upon a maxim
+ which, at the same time, involves its own universal validity for every
+ rational being." For that in using means for every end I should limit my
+ maxim by the condition of its holding good as a law for every subject,
+ this comes to the same thing as that the fundamental principle of all
+ maxims of action must be that the subject of all ends, i.e., the rational
+ being himself, be never employed merely as means, but as the supreme
+ condition restricting the use of all means, that is in every case as an
+ end likewise.
+ </p>
+ <p>
+ It follows incontestably that, to whatever laws any rational being may be
+ subject, he being an end in himself must be able to regard himself as also
+ legislating universally in respect of these same laws, since it is just
+ this fitness of his maxims for universal legislation that distinguishes
+ him as an end in himself; also it follows that this implies his dignity
+ (prerogative) above all mere physical beings, that he must always take his
+ maxims from the point of view which regards himself and, likewise, every
+ other rational being as law-giving beings (on which account they are
+ called persons). In this way a world of rational beings (mundus
+ intelligibilis) is possible as a kingdom of ends, and this by virtue of
+ the legislation proper to all persons as members. Therefore every rational
+ being must so act as if he were by his maxims in every case a legislating
+ member in the universal kingdom of ends. The formal principle of these
+ maxims is: "So act as if thy maxim were to serve likewise as the universal
+ law (of all rational beings)." A kingdom of ends is thus only possible on
+ the analogy of a kingdom of nature, the former however only by maxims,
+ that is self-imposed rules, the latter only by the laws of efficient
+ causes acting under necessitation from without. Nevertheless, although the
+ system of nature is looked upon as a machine, yet so far as it has
+ reference to rational beings as its ends, it is given on this account the
+ name of a kingdom of nature. Now such a kingdom of ends would be actually
+ realized by means of maxims conforming to the canon which the categorical
+ imperative prescribes to all rational beings, if they were universally
+ followed. But although a rational being, even if he punctually follows
+ this maxim himself, cannot reckon upon all others being therefore true to
+ the same, nor expect that the kingdom of nature and its orderly
+ arrangements shall be in harmony with him as a fitting member, so as to
+ form a kingdom of ends to which he himself contributes, that is to say,
+ that it shall favour his expectation of happiness, still that law: "Act
+ according to the maxims of a member of a merely possible kingdom of ends
+ legislating in it universally," remains in its full force, inasmuch as it
+ commands categorically. And it is just in this that the paradox lies; that
+ the mere dignity of man as a rational creature, without any other end or
+ advantage to be attained thereby, in other words, respect for a mere idea,
+ should yet serve as an inflexible precept of the will, and that it is
+ precisely in this independence of the maxim on all such springs of action
+ that its sublimity consists; and it is this that makes every rational
+ subject worthy to be a legislative member in the kingdom of ends: for
+ otherwise he would have to be conceived only as subject to the physical
+ law of his wants. And although we should suppose the kingdom of nature and
+ the kingdom of ends to be united under one sovereign, so that the latter
+ kingdom thereby ceased to be a mere idea and acquired true reality, then
+ it would no doubt gain the accession of a strong spring, but by no means
+ any increase of its intrinsic worth. For this sole absolute lawgiver must,
+ notwithstanding this, be always conceived as estimating the worth of
+ rational beings only by their disinterested behaviour, as prescribed to
+ themselves from that idea [the dignity of man] alone. The essence of
+ things is not altered by their external relations, and that which,
+ abstracting from these, alone constitutes the absolute worth of man, is
+ also that by which he must be judged, whoever the judge may be, and even
+ by the Supreme Being. Morality, then, is the relation of actions to the
+ relation of actions will, that is, to the autonomy of potential universal
+ legislation by its maxims. An action that is consistent with the autonomy
+ of the will is permitted; one that does not agree therewith is forbidden.
+ A will whose maxims necessarily coincide with the laws of autonomy is a
+ holy will, good absolutely. The dependence of a will not absolutely good
+ on the principle of autonomy (moral necessitation) is obligation. This,
+ then, cannot be applied to a holy being. The objective necessity of
+ actions from obligation is called duty.
+ </p>
+ <p>
+ From what has just been said, it is easy to see how it happens that,
+ although the conception of duty implies subjection to the law, we yet
+ ascribe a certain dignity and sublimity to the person who fulfils all his
+ duties. There is not, indeed, any sublimity in him, so far as he is
+ subject to the moral law; but inasmuch as in regard to that very law he is
+ likewise a legislator, and on that account alone subject to it, he has
+ sublimity. We have also shown above that neither fear nor inclination, but
+ simply respect for the law, is the spring which can give actions a moral
+ worth. Our own will, so far as we suppose it to act only under the
+ condition that its maxims are potentially universal laws, this ideal will
+ which is possible to us is the proper object of respect; and the dignity
+ of humanity consists just in this capacity of being universally
+ legislative, though with the condition that it is itself subject to this
+ same legislation.

+ The Autonomy of the Will as the Supreme Principle of Morality
+ </h2>
+ <p>
+ Autonomy of the will is that property of it by which it is a law to itself
+ (independently of any property of the objects of volition). The principle
+ of autonomy then is: "Always so to choose that the same volition shall
+ comprehend the maxims of our choice as a universal law." We cannot prove
+ that this practical rule is an imperative, i.e., that the will of every
+ rational being is necessarily bound to it as a condition, by a mere
+ analysis of the conceptions which occur in it, since it is a synthetical
+ proposition; we must advance beyond the cognition of the objects to a
+ critical examination of the subject, that is, of the pure practical
+ reason, for this synthetic proposition which commands apodeictically must
+ be capable of being cognized wholly a priori. This matter, however, does
+ not belong to the present section. But that the principle of autonomy in
+ question is the sole principle of morals can be readily shown by mere
+ analysis of the conceptions of morality. For by this analysis we find that
+ its principle must be a categorical imperative and that what this commands
+ is neither more nor less than this very autonomy.

+ <h2>
+ Heteronomy of the Will as the Source of all spurious Principles of
+ Morality
+ </h2>
+ <p>
+ If the will seeks the law which is to determine it anywhere else than in
+ the fitness of its maxims to be universal laws of its own dictation,
+ consequently if it goes out of itself and seeks this law in the character
+ of any of its objects, there always results heteronomy. The will in that
+ case does not give itself the law, but it is given by the object through
+ its relation to the will. This relation, whether it rests on inclination
+ or on conceptions of reason, only admits of hypothetical imperatives: "I
+ ought to do something because I wish for something else." On the contrary,
+ the moral, and therefore categorical, imperative says: "I ought to do so
+ and so, even though I should not wish for anything else." E.g., the former
+ says: "I ought not to lie, if I would retain my reputation"; the latter
+ says: "I ought not to lie, although it should not bring me the least
+ discredit." The latter therefore must so far abstract from all objects
+ that they shall have no influence on the will, in order that practical
+ reason (will) may not be restricted to administering an interest not
+ belonging to it, but may simply show its own commanding authority as the
+ supreme legislation. Thus, e.g., I ought to endeavour to promote the
+ happiness of others, not as if its realization involved any concern of
+ mine (whether by immediate inclination or by any satisfaction indirectly
+ gained through reason), but simply because a maxim which excludes it
+ cannot be comprehended as a universal law in one and the same volition.

+ <h2>
+ Classification of all Principles of Morality which can be founded on the
+ Conception of Heteronomy
+ </h2>
+ <p>
+ Here as elsewhere human reason in its pure use, so long as it was not
+ critically examined, has first tried all possible wrong ways before it
+ succeeded in finding the one true way.
+ </p>
+ <p>
+ All principles which can be taken from this point of view are either
+ empirical or rational. The former, drawn from the principle of happiness,
+ are built on physical or moral feelings; the latter, drawn from the
+ principle of perfection, are built either on the rational conception of
+ perfection as a possible effect, or on that of an independent perfection
+ (the will of God) as the determining cause of our will.
+ </p>
+ <p>
+ Empirical principles are wholly incapable of serving as a foundation for
+ moral laws. For the universality with which these should hold for all
+ rational beings without distinction, the unconditional practical necessity
+ which is thereby imposed on them, is lost when their foundation is taken
+ from the particular constitution of human nature, or the accidental
+ circumstances in which it is placed. The principle of private happiness,
+ however, is the most objectionable, not merely because it is false, and
+ experience contradicts the supposition that prosperity is always
+ proportioned to good conduct, nor yet merely because it contributes
+ nothing to the establishment of morality- since it is quite a different
+ thing to make a prosperous man and a good man, or to make one prudent and
+ sharp-sighted for his own interests and to make him virtuous- but because
+ the springs it provides for morality are such as rather undermine it and
+ destroy its sublimity, since they put the motives to virtue and to vice in
+ the same class and only teach us to make a better calculation, the
+ specific difference between virtue and vice being entirely extinguished.
+ On the other hand, as to moral feeling, this supposed special sense, * the
+ appeal to it is indeed superficial when those who cannot think believe
+ that feeling will help them out, even in what concerns general laws: and
+ besides, feelings, which naturally differ infinitely in degree, cannot
+ furnish a uniform standard of good and evil, nor has anyone a right to
+ form judgements for others by his own feelings: nevertheless this moral
+ feeling is nearer to morality and its dignity in this respect, that it
+ pays virtue the honour of ascribing to her immediately the satisfaction
+ and esteem we have for her and does not, as it were, tell her to her face
+ that we are not attached to her by her beauty but by profit.
+ </p>
+<pre xml:space="preserve">
+ * I class the principle of moral feeling under that of
+ happiness, because every empirical interest promises to
+ contribute to our well-being by the agreeableness that a
+ thing affords, whether it be immediately and without a view
+ to profit, or whether profit be regarded. We must likewise,
+ with Hutcheson, class the principle of sympathy with the
+ happiness of others under his assumed moral sense.
+</pre>
+ <p>
+ Amongst the rational principles of morality, the ontological conception of
+ perfection, notwithstanding its defects, is better than the theological
+ conception which derives morality from a Divine absolutely perfect will.
+ The former is, no doubt, empty and indefinite and consequently useless for
+ finding in the boundless field of possible reality the greatest amount
+ suitable for us; moreover, in attempting to distinguish specifically the
+ reality of which we are now speaking from every other, it inevitably tends
+ to turn in a circle and cannot avoid tacitly presupposing the morality
+ which it is to explain; it is nevertheless preferable to the theological
+ view, first, because we have no intuition of the divine perfection and can
+ only deduce it from our own conceptions, the most important of which is
+ that of morality, and our explanation would thus be involved in a gross
+ circle; and, in the next place, if we avoid this, the only notion of the
+ Divine will remaining to us is a conception made up of the attributes of
+ desire of glory and dominion, combined with the awful conceptions of might
+ and vengeance, and any system of morals erected on this foundation would
+ be directly opposed to morality.
+ </p>
+ <p>
+ However, if I had to choose between the notion of the moral sense and that
+ of perfection in general (two systems which at least do not weaken
+ morality, although they are totally incapable of serving as its
+ foundation), then I should decide for the latter, because it at least
+ withdraws the decision of the question from the sensibility and brings it
+ to the court of pure reason; and although even here it decides nothing, it
+ at all events preserves the indefinite idea (of a will good in itself free
+ from corruption, until it shall be more precisely defined.
+ </p>
+ <p>
+ For the rest I think I may be excused here from a detailed refutation of
+ all these doctrines; that would only be superfluous labour, since it is so
+ easy, and is probably so well seen even by those whose office requires
+ them to decide for one of these theories (because their hearers would not
+ tolerate suspension of judgement). But what interests us more here is to
+ know that the prime foundation of morality laid down by all these
+ principles is nothing but heteronomy of the will, and for this reason they
+ must necessarily miss their aim.
+ </p>
+ <p>
+ In every case where an object of the will has to be supposed, in order
+ that the rule may be prescribed which is to determine the will, there the
+ rule is simply heteronomy; the imperative is conditional, namely, if or
+ because one wishes for this object, one should act so and so: hence it can
+ never command morally, that is, categorically. Whether the object
+ determines the will by means of inclination, as in the principle of
+ private happiness, or by means of reason directed to objects of our
+ possible volition generally, as in the principle of perfection, in either
+ case the will never determines itself immediately by the conception of the
+ action, but only by the influence which the foreseen effect of the action
+ has on the will; I ought to do something, on this account, because I wish
+ for something else; and here there must be yet another law assumed in me
+ as its subject, by which I necessarily will this other thing, and this law
+ again requires an imperative to restrict this maxim. For the influence
+ which the conception of an object within the reach of our faculties can
+ exercise on the will of the subject, in consequence of its natural
+ properties, depends on the nature of the subject, either the sensibility
+ (inclination and taste), or the understanding and reason, the employment
+ of which is by the peculiar constitution of their nature attended with
+ satisfaction. It follows that the law would be, properly speaking, given
+ by nature, and, as such, it must be known and proved by experience and
+ would consequently be contingent and therefore incapable of being an
+ apodeictic practical rule, such as the moral rule must be. Not only so,
+ but it is inevitably only heteronomy; the will does not give itself the
+ law, but is given by a foreign impulse by means of a particular natural
+ constitution of the subject adapted to receive it. An absolutely good
+ will, then, the principle of which must be a categorical imperative, will
+ be indeterminate as regards all objects and will contain merely the form
+ of volition generally, and that as autonomy, that is to say, the
+ capability of the maxims of every good will to make themselves a universal
+ law, is itself the only law which the will of every rational being imposes
+ on itself, without needing to assume any spring or interest as a
+ foundation.
+ </p>
+ <p>
+ How such a synthetical practical a priori proposition is possible, and why
+ it is necessary, is a problem whose solution does not lie within the
+ bounds of the metaphysic of morals; and we have not here affirmed its
+ truth, much less professed to have a proof of it in our power. We simply
+ showed by the development of the universally received notion of morality
+ that an autonomy of the will is inevitably connected with it, or rather is
+ its foundation. Whoever then holds morality to be anything real, and not a
+ chimerical idea without any truth, must likewise admit the principle of it
+ that is here assigned. This section then, like the first, was merely
+ analytical. Now to prove that morality is no creation of the brain, which
+ it cannot be if the categorical imperative and with it the autonomy of the
+ will is true, and as an a priori principle absolutely necessary, this
+ supposes the possibility of a synthetic use of pure practical reason,
+ which however we cannot venture on without first giving a critical
+ examination of this faculty of reason. In the concluding section we shall
+ give the principal outlines of this critical examination as far as is
+ sufficient for our purpose.

+ The Concept of Freedom is the Key that explains the Autonomy of the Will
+ </h2>
+ <p>
+ The will is a kind of causality belonging to living beings in so far as
+ they are rational, and freedom would be this property of such causality
+ that it can be efficient, independently of foreign causes determining it;
+ just as physical necessity is the property that the causality of all
+ irrational beings has of being determined to activity by the influence of
+ foreign causes.
+ </p>
+ <p>
+ The preceding definition of freedom is negative and therefore unfruitful
+ for the discovery of its essence, but it leads to a positive conception
+ which is so much the more full and fruitful.
+ </p>
+ <p>
+ Since the conception of causality involves that of laws, according to
+ which, by something that we call cause, something else, namely the effect,
+ must be produced; hence, although freedom is not a property of the will
+ depending on physical laws, yet it is not for that reason lawless; on the
+ contrary it must be a causality acting according to immutable laws, but of
+ a peculiar kind; otherwise a free will would be an absurdity. Physical
+ necessity is a heteronomy of the efficient causes, for every effect is
+ possible only according to this law, that something else determines the
+ efficient cause to exert its causality. What else then can freedom of the
+ will be but autonomy, that is, the property of the will to be a law to
+ itself? But the proposition: "The will is in every action a law to
+ itself," only expresses the principle: "To act on no other maxim than that
+ which can also have as an object itself as a universal law." Now this is
+ precisely the formula of the categorical imperative and is the principle
+ of morality, so that a free will and a will subject to moral laws are one
+ and the same.
+ </p>
+ <p>
+ On the hypothesis, then, of freedom of the will, morality together with
+ its principle follows from it by mere analysis of the conception. However,
+ the latter is a synthetic proposition; viz., an absolutely good will is
+ that whose maxim can always include itself regarded as a universal law;
+ for this property of its maxim can never be discovered by analysing the
+ conception of an absolutely good will. Now such synthetic propositions are
+ only possible in this way: that the two cognitions are connected together
+ by their union with a third in which they are both to be found. The
+ positive concept of freedom furnishes this third cognition, which cannot,
+ as with physical causes, be the nature of the sensible world (in the
+ concept of which we find conjoined the concept of something in relation as
+ cause to something else as effect). We cannot now at once show what this
+ third is to which freedom points us and of which we have an idea a priori,
+ nor can we make intelligible how the concept of freedom is shown to be
+ legitimate from principles of pure practical reason and with it the
+ possibility of a categorical imperative; but some further preparation is
+ required.

+ Freedom must be presupposed as a Property of the Will of all Rational
+ Beings
+ </h2>
+ <p>
+ It is not enough to predicate freedom of our own will, from Whatever
+ reason, if we have not sufficient grounds for predicating the same of all
+ rational beings. For as morality serves as a law for us only because we
+ are rational beings, it must also hold for all rational beings; and as it
+ must be deduced simply from the property of freedom, it must be shown that
+ freedom also is a property of all rational beings. It is not enough, then,
+ to prove it from certain supposed experiences of human nature (which
+ indeed is quite impossible, and it can only be shown a priori), but we
+ must show that it belongs to the activity of all rational beings endowed
+ with a will. Now I say every being that cannot act except under the idea
+ of freedom is just for that reason in a practical point of view really
+ free, that is to say, all laws which are inseparably connected with
+ freedom have the same force for him as if his will had been shown to be
+ free in itself by a proof theoretically conclusive. * Now I affirm that we
+ must attribute to every rational being which has a will that it has also
+ the idea of freedom and acts entirely under this idea. For in such a being
+ we conceive a reason that is practical, that is, has causality in
+ reference to its objects. Now we cannot possibly conceive a reason
+ consciously receiving a bias from any other quarter with respect to its
+ judgements, for then the subject would ascribe the determination of its
+ judgement not to its own reason, but to an impulse. It must regard itself
+ as the author of its principles independent of foreign influences.
+ Consequently as practical reason or as the will of a rational being it
+ must regard itself as free, that is to say, the will of such a being
+ cannot be a will of its own except under the idea of freedom. This idea
+ must therefore in a practical point of view be ascribed to every rational
+ being.
+ </p>
+<pre xml:space="preserve">
+ * I adopt this method of assuming freedom merely as an idea
+ which rational beings suppose in their actions, in order to
+ avoid the necessity of proving it in its theoretical aspect
+ also. The former is sufficient for my purpose; for even
+ though the speculative proof should not be made out, yet a
+ being that cannot act except with the idea of freedom is
+ bound by the same laws that would oblige a being who was
+ actually free. Thus we can escape here from the onus which
+ presses on the theory.

+ <h2>
+ Of the Interest attaching to the Ideas of Morality
+ </h2>
+ <p>
+ We have finally reduced the definite conception of morality to the idea of
+ freedom. This latter, however, we could not prove to be actually a
+ property of ourselves or of human nature; only we saw that it must be
+ presupposed if we would conceive a being as rational and conscious of its
+ causality in respect of its actions, i.e., as endowed with a will; and so
+ we find that on just the same grounds we must ascribe to every being
+ endowed with reason and will this attribute of determining itself to
+ action under the idea of its freedom.
+ </p>
+ <p>
+ Now it resulted also from the presupposition of these ideas that we became
+ aware of a law that the subjective principles of action, i.e., maxims,
+ must always be so assumed that they can also hold as objective, that is,
+ universal principles, and so serve as universal laws of our own dictation.
+ But why then should I subject myself to this principle and that simply as
+ a rational being, thus also subjecting to it all other being endowed with
+ reason? I will allow that no interest urges me to this, for that would not
+ give a categorical imperative, but I must take an interest in it and
+ discern how this comes to pass; for this properly an "I ought" is properly
+ an "I would," valid for every rational being, provided only that reason
+ determined his actions without any hindrance. But for beings that are in
+ addition affected as we are by springs of a different kind, namely,
+ sensibility, and in whose case that is not always done which reason alone
+ would do, for these that necessity is expressed only as an "ought," and
+ the subjective necessity is different from the objective.
+ </p>
+ <p>
+ It seems then as if the moral law, that is, the principle of autonomy of
+ the will, were properly speaking only presupposed in the idea of freedom,
+ and as if we could not prove its reality and objective necessity
+ independently. In that case we should still have gained something
+ considerable by at least determining the true principle more exactly than
+ had previously been done; but as regards its validity and the practical
+ necessity of subjecting oneself to it, we should not have advanced a step.
+ For if we were asked why the universal validity of our maxim as a law must
+ be the condition restricting our actions, and on what we ground the worth
+ which we assign to this manner of acting- a worth so great that there
+ cannot be any higher interest; and if we were asked further how it happens
+ that it is by this alone a man believes he feels his own personal worth,
+ in comparison with which that of an agreeable or disagreeable condition is
+ to be regarded as nothing, to these questions we could give no
+ satisfactory answer.
+ </p>
+ <p>
+ We find indeed sometimes that we can take an interest in a personal
+ quality which does not involve any interest of external condition,
+ provided this quality makes us capable of participating in the condition
+ in case reason were to effect the allotment; that is to say, the mere
+ being worthy of happiness can interest of itself even without the motive
+ of participating in this happiness. This judgement, however, is in fact
+ only the effect of the importance of the moral law which we before
+ presupposed (when by the idea of freedom we detach ourselves from every
+ empirical interest); but that we ought to detach ourselves from these
+ interests, i.e., to consider ourselves as free in action and yet as
+ subject to certain laws, so as to find a worth simply in our own person
+ which can compensate us for the loss of everything that gives worth to our
+ condition; this we are not yet able to discern in this way, nor do we see
+ how it is possible so to act- in other words, whence the moral law derives
+ its obligation.
+ </p>
+ <p>
+ It must be freely admitted that there is a sort of circle here from which
+ it seems impossible to escape. In the order of efficient causes we assume
+ ourselves free, in order that in the order of ends we may conceive
+ ourselves as subject to moral laws: and we afterwards conceive ourselves
+ as subject to these laws, because we have attributed to ourselves freedom
+ of will: for freedom and self-legislation of will are both autonomy and,
+ therefore, are reciprocal conceptions, and for this very reason one must
+ not be used to explain the other or give the reason of it, but at most
+ only logical purposes to reduce apparently different notions of the same
+ object to one single concept (as we reduce different fractions of the same
+ value to the lowest terms).
+ </p>
+ <p>
+ One resource remains to us, namely, to inquire whether we do not occupy
+ different points of view when by means of freedom we think ourselves as
+ causes efficient a priori, and when we form our conception of ourselves
+ from our actions as effects which we see before our eyes.
+ </p>
+ <p>
+ It is a remark which needs no subtle reflection to make, but which we may
+ assume that even the commonest understanding can make, although it be
+ after its fashion by an obscure discernment of judgement which it calls
+ feeling, that all the "ideas" that come to us involuntarily (as those of
+ the senses) do not enable us to know objects otherwise than as they affect
+ us; so that what they may be in themselves remains unknown to us, and
+ consequently that as regards "ideas" of this kind even with the closest
+ attention and clearness that the understanding can apply to them, we can
+ by them only attain to the knowledge of appearances, never to that of
+ things in themselves. As soon as this distinction has once been made
+ (perhaps merely in consequence of the difference observed between the
+ ideas given us from without, and in which we are passive, and those that
+ we produce simply from ourselves, and in which we show our own activity),
+ then it follows of itself that we must admit and assume behind the
+ appearance something else that is not an appearance, namely, the things in
+ themselves; although we must admit that as they can never be known to us
+ except as they affect us, we can come no nearer to them, nor can we ever
+ know what they are in themselves. This must furnish a distinction, however
+ crude, between a world of sense and the world of understanding, of which
+ the former may be different according to the difference of the sensuous
+ impressions in various observers, while the second which is its basis
+ always remains the same, Even as to himself, a man cannot pretend to know
+ what he is in himself from the knowledge he has by internal sensation. For
+ as he does not as it were create himself, and does not come by the
+ conception of himself a priori but empirically, it naturally follows that
+ he can obtain his knowledge even of himself only by the inner sense and,
+ consequently, only through the appearances of his nature and the way in
+ which his consciousness is affected. At the same time beyond these
+ characteristics of his own subject, made up of mere appearances, he must
+ necessarily suppose something else as their basis, namely, his ego,
+ whatever its characteristics in itself may be. Thus in respect to mere
+ perception and receptivity of sensations he must reckon himself as
+ belonging to the world of sense; but in respect of whatever there may be
+ of pure activity in him (that which reaches consciousness immediately and
+ not through affecting the senses), he must reckon himself as belonging to
+ the intellectual world, of which, however, he has no further knowledge. To
+ such a conclusion the reflecting man must come with respect to all the
+ things which can be presented to him: it is probably to be met with even
+ in persons of the commonest understanding, who, as is well known, are very
+ much inclined to suppose behind the objects of the senses something else
+ invisible and acting of itself. They spoil it, however, by presently
+ sensualizing this invisible again; that is to say, wanting to make it an
+ object of intuition, so that they do not become a whit the wiser.
+ </p>
+ <p>
+ Now man really finds in himself a faculty by which he distinguishes
+ himself from everything else, even from himself as affected by objects,
+ and that is reason. This being pure spontaneity is even elevated above the
+ understanding. For although the latter is a spontaneity and does not, like
+ sense, merely contain intuitions that arise when we are affected by things
+ (and are therefore passive), yet it cannot produce from its activity any
+ other conceptions than those which merely serve to bring the intuitions of
+ sense under rules and, thereby, to unite them in one consciousness, and
+ without this use of the sensibility it could not think at all; whereas, on
+ the contrary, reason shows so pure a spontaneity in the case of what I
+ call ideas [ideal conceptions] that it thereby far transcends everything
+ that the sensibility can give it, and exhibits its most important function
+ in distinguishing the world of sense from that of understanding, and
+ thereby prescribing the limits of the understanding itself.
+ </p>
+ <p>
+ For this reason a rational being must regard himself qua intelligence (not
+ from the side of his lower faculties) as belonging not to the world of
+ sense, but to that of understanding; hence he has two points of view from
+ which he can regard himself, and recognise laws of the exercise of his
+ faculties, and consequently of all his actions: first, so far as he
+ belongs to the world of sense, he finds himself subject to laws of nature
+ (heteronomy); secondly, as belonging to the intelligible world, under laws
+ which being independent of nature have their foundation not in experience
+ but in reason alone.
+ </p>
+ <p>
+ As a rational being, and consequently belonging to the intelligible world,
+ man can never conceive the causality of his own will otherwise than on
+ condition of the idea of freedom, for independence of the determinate
+ causes of the sensible world (an independence which reason must always
+ ascribe to itself) is freedom. Now the idea of freedom is inseparably
+ connected with the conception of autonomy, and this again with the
+ universal principle of morality which is ideally the foundation of all
+ actions of rational beings, just as the law of nature is of all phenomena.
+ </p>
+ <p>
+ Now the suspicion is removed which we raised above, that there was a
+ latent circle involved in our reasoning from freedom to autonomy, and from
+ this to the moral law, viz.: that we laid down the idea of freedom because
+ of the moral law only that we might afterwards in turn infer the latter
+ from freedom, and that consequently we could assign no reason at all for
+ this law, but could only [present] it as a petitio principii which well
+ disposed minds would gladly concede to us, but which we could never put
+ forward as a provable proposition. For now we see that, when we conceive
+ ourselves as free, we transfer ourselves into the world of understanding
+ as members of it and recognise the autonomy of the will with its
+ consequence, morality; whereas, if we conceive ourselves as under
+ obligation, we consider ourselves as belonging to the world of sense and
+ at the same time to the world of understanding.

+ <h2>
+ How is a Categorical Imperative Possible?
+ </h2>
+ <p>
+ Every rational being reckons himself qua intelligence as belonging to the
+ world of understanding, and it is simply as an efficient cause belonging
+ to that world that he calls his causality a will. On the other side he is
+ also conscious of himself as a part of the world of sense in which his
+ actions, which are mere appearances [phenomena] of that causality, are
+ displayed; we cannot, however, discern how they are possible from this
+ causality which we do not know; but instead of that, these actions as
+ belonging to the sensible world must be viewed as determined by other
+ phenomena, namely, desires and inclinations. If therefore I were only a
+ member of the world of understanding, then all my actions would perfectly
+ conform to the principle of autonomy of the pure will; if I were only a
+ part of the world of sense, they would necessarily be assumed to conform
+ wholly to the natural law of desires and inclinations, in other words, to
+ the heteronomy of nature. (The former would rest on morality as the
+ supreme principle, the latter on happiness.) Since, however, the world of
+ understanding contains the foundation of the world of sense, and
+ consequently of its laws also, and accordingly gives the law to my will
+ (which belongs wholly to the world of understanding) directly, and must be
+ conceived as doing so, it follows that, although on the one side I must
+ regard myself as a being belonging to the world of sense, yet on the other
+ side I must recognize myself as subject as an intelligence to the law of
+ the world of understanding, i.e., to reason, which contains this law in
+ the idea of freedom, and therefore as subject to the autonomy of the will:
+ consequently I must regard the laws of the world of understanding as
+ imperatives for me and the actions which conform to them as duties.
+ </p>
+ <p>
+ And thus what makes categorical imperatives possible is this, that the
+ idea of freedom makes me a member of an intelligible world, in consequence
+ of which, if I were nothing else, all my actions would always conform to
+ the autonomy of the will; but as I at the same time intuite myself as a
+ member of the world of sense, they ought so to conform, and this
+ categorical "ought" implies a synthetic a priori proposition, inasmuch as
+ besides my will as affected by sensible desires there is added further the
+ idea of the same will but as belonging to the world of the understanding,
+ pure and practical of itself, which contains the supreme condition
+ according to reason of the former will; precisely as to the intuitions of
+ sense there are added concepts of the understanding which of themselves
+ signify nothing but regular form in general and in this way synthetic a
+ priori propositions become possible, on which all knowledge of physical
+ nature rests.
+ </p>
+ <p>
+ The practical use of common human reason confirms this reasoning. There is
+ no one, not even the most consummate villain, provided only that he is
+ otherwise accustomed to the use of reason, who, when we set before him
+ examples of honesty of purpose, of steadfastness in following good maxims,
+ of sympathy and general benevolence (even combined with great sacrifices
+ of advantages and comfort), does not wish that he might also possess these
+ qualities. Only on account of his inclinations and impulses he cannot
+ attain this in himself, but at the same time he wishes to be free from
+ such inclinations which are burdensome to himself. He proves by this that
+ he transfers himself in thought with a will free from the impulses of the
+ sensibility into an order of things wholly different from that of his
+ desires in the field of the sensibility; since he cannot expect to obtain
+ by that wish any gratification of his desires, nor any position which
+ would satisfy any of his actual or supposable inclinations (for this would
+ destroy the pre-eminence of the very idea which wrests that wish from
+ him): he can only expect a greater intrinsic worth of his own person. This
+ better person, however, he imagines himself to be when be transfers
+ himself to the point of view of a member of the world of the
+ understanding, to which he is involuntarily forced by the idea of freedom,
+ i.e., of independence on determining causes of the world of sense; and
+ from this point of view he is conscious of a good will, which by his own
+ confession constitutes the law for the bad will that he possesses as a
+ member of the world of sense- a law whose authority he recognizes while
+ transgressing it. What he morally "ought" is then what he necessarily
+ "would," as a member of the world of the understanding, and is conceived
+ by him as an "ought" only inasmuch as he likewise considers himself as a
+ member of the world of sense.

+ <h2>
+ Of the Extreme Limits of all Practical Philosophy.
+ </h2>
+ <p>
+ All men attribute to themselves freedom of will. Hence come all judgements
+ upon actions as being such as ought to have been done, although they have
+ not been done. However, this freedom is not a conception of experience,
+ nor can it be so, since it still remains, even though experience shows the
+ contrary of what on supposition of freedom are conceived as its necessary
+ consequences. On the other side it is equally necessary that everything
+ that takes place should be fixedly determined according to laws of nature.
+ This necessity of nature is likewise not an empirical conception, just for
+ this reason, that it involves the motion of necessity and consequently of
+ a priori cognition. But this conception of a system of nature is confirmed
+ by experience; and it must even be inevitably presupposed if experience
+ itself is to be possible, that is, a connected knowledge of the objects of
+ sense resting on general laws. Therefore freedom is only an idea of
+ reason, and its objective reality in itself is doubtful; while nature is a
+ concept of the understanding which proves, and must necessarily prove, its
+ reality in examples of experience.
+ </p>
+ <p>
+ There arises from this a dialectic of reason, since the freedom attributed
+ to the will appears to contradict the necessity of nature, and placed
+ between these two ways reason for speculative purposes finds the road of
+ physical necessity much more beaten and more appropriate than that of
+ freedom; yet for practical purposes the narrow footpath of freedom is the
+ only one on which it is possible to make use of reason in our conduct;
+ hence it is just as impossible for the subtlest philosophy as for the
+ commonest reason of men to argue away freedom. Philosophy must then assume
+ that no real contradiction will be found between freedom and physical
+ necessity of the same human actions, for it cannot give up the conception
+ of nature any more than that of freedom.
+ </p>
+ <p>
+ Nevertheless, even though we should never be able to comprehend how
+ freedom is possible, we must at least remove this apparent contradiction
+ in a convincing manner. For if the thought of freedom contradicts either
+ itself or nature, which is equally necessary, it must in competition with
+ physical necessity be entirely given up.
+ </p>
+ <p>
+ It would, however, be impossible to escape this contradiction if the
+ thinking subject, which seems to itself free, conceived itself in the same
+ sense or in the very same relation when it calls itself free as when in
+ respect of the same action it assumes itself to be subject to the law of
+ nature. Hence it is an indispensable problem of speculative philosophy to
+ show that its illusion respecting the contradiction rests on this, that we
+ think of man in a different sense and relation when we call him free and
+ when we regard him as subject to the laws of nature as being part and
+ parcel of nature. It must therefore show that not only can both these very
+ well co-exist, but that both must be thought as necessarily united in the
+ same subject, since otherwise no reason could be given why we should
+ burden reason with an idea which, though it may possibly without
+ contradiction be reconciled with another that is sufficiently established,
+ yet entangles us in a perplexity which sorely embarrasses reason in its
+ theoretic employment. This duty, however, belongs only to speculative
+ philosophy. The philosopher then has no option whether he will remove the
+ apparent contradiction or leave it untouched; for in the latter case the
+ theory respecting this would be bonum vacans, into the possession of which
+ the fatalist would have a right to enter and chase all morality out of its
+ supposed domain as occupying it without title.
+ </p>
+ <p>
+ We cannot however as yet say that we are touching the bounds of practical
+ philosophy. For the settlement of that controversy does not belong to it;
+ it only demands from speculative reason that it should put an end to the
+ discord in which it entangles itself in theoretical questions, so that
+ practical reason may have rest and security from external attacks which
+ might make the ground debatable on which it desires to build.
+ </p>
+ <p>
+ The claims to freedom of will made even by common reason are founded on
+ the consciousness and the admitted supposition that reason is independent
+ of merely subjectively determined causes which together constitute what
+ belongs to sensation only and which consequently come under the general
+ designation of sensibility. Man considering himself in this way as an
+ intelligence places himself thereby in a different order of things and in
+ a relation to determining grounds of a wholly different kind when on the
+ one hand he thinks of himself as an intelligence endowed with a will, and
+ consequently with causality, and when on the other he perceives himself as
+ a phenomenon in the world of sense (as he really is also), and affirms
+ that his causality is subject to external determination according to laws
+ of nature. Now he soon becomes aware that both can hold good, nay, must
+ hold good at the same time. For there is not the smallest contradiction in
+ saying that a thing in appearance (belonging to the world of sense) is
+ subject to certain laws, of which the very same as a thing or being in
+ itself is independent, and that he must conceive and think of himself in
+ this twofold way, rests as to the first on the consciousness of himself as
+ an object affected through the senses, and as to the second on the
+ consciousness of himself as an intelligence, i.e., as independent on
+ sensible impressions in the employment of his reason (in other words as
+ belonging to the world of understanding).
+ </p>
+ <p>
+ Hence it comes to pass that man claims the possession of a will which
+ takes no account of anything that comes under the head of desires and
+ inclinations and, on the contrary, conceives actions as possible to him,
+ nay, even as necessary which can only be done by disregarding all desires
+ and sensible inclinations. The causality of such actions lies in him as an
+ intelligence and in the laws of effects and actions [which depend] on the
+ principles of an intelligible world, of which indeed he knows nothing more
+ than that in it pure reason alone independent of sensibility gives the
+ law; moreover since it is only in that world, as an intelligence, that he
+ is his proper self (being as man only the appearance of himself), those
+ laws apply to him directly and categorically, so that the incitements of
+ inclinations and appetites (in other words the whole nature of the world
+ of sense) cannot impair the laws of his volition as an intelligence. Nay,
+ he does not even hold himself responsible for the former or ascribe them
+ to his proper self, i.e., his will: he only ascribes to his will any
+ indulgence which he might yield them if he allowed them to influence his
+ maxims to the prejudice of the rational laws of the will.
+ </p>
+ <p>
+ When practical reason thinks itself into a world of understanding, it does
+ not thereby transcend its own limits, as it would if it tried to enter it
+ by intuition or sensation. The former is only a negative thought in
+ respect of the world of sense, which does not give any laws to reason in
+ determining the will and is positive only in this single point that this
+ freedom as a negative characteristic is at the same time conjoined with a
+ (positive) faculty and even with a causality of reason, which we designate
+ a will, namely a faculty of so acting that the principle of the actions
+ shall conform to the essential character of a rational motive, i.e., the
+ condition that the maxim have universal validity as a law. But were it to
+ borrow an object of will, that is, a motive, from the world of
+ understanding, then it would overstep its bounds and pretend to be
+ acquainted with something of which it knows nothing. The conception of a
+ world of the understanding is then only a point of view which reason finds
+ itself compelled to take outside the appearances in order to conceive
+ itself as practical, which would not be possible if the influences of the
+ sensibility had a determining power on man, but which is necessary unless
+ he is to be denied the consciousness of himself as an intelligence and,
+ consequently, as a rational cause, energizing by reason, that is,
+ operating freely. This thought certainly involves the idea of an order and
+ a system of laws different from that of the mechanism of nature which
+ belongs to the sensible world; and it makes the conception of an
+ intelligible world necessary (that is to say, the whole system of rational
+ beings as things in themselves). But it does not in the least authorize us
+ to think of it further than as to its formal condition only, that is, the
+ universality of the maxims of the will as laws, and consequently the
+ autonomy of the latter, which alone is consistent with its freedom;
+ whereas, on the contrary, all laws that refer to a definite object give
+ heteronomy, which only belongs to laws of nature and can only apply to the
+ sensible world.
+ </p>
+ <p>
+ But reason would overstep all its bounds if it undertook to explain how
+ pure reason can be practical, which would be exactly the same problem as
+ to explain how freedom is possible.
+ </p>
+ <p>
+ For we can explain nothing but that which we can reduce to laws, the
+ object of which can be given in some possible experience. But freedom is a
+ mere idea, the objective reality of which can in no wise be shown
+ according to laws of nature, and consequently not in any possible
+ experience; and for this reason it can never be comprehended or
+ understood, because we cannot support it by any sort of example or
+ analogy. It holds good only as a necessary hypothesis of reason in a being
+ that believes itself conscious of a will, that is, of a faculty distinct
+ from mere desire (namely, a faculty of determining itself to action as an
+ intelligence, in other words, by laws of reason independently on natural
+ instincts). Now where determination according to laws of nature ceases,
+ there all explanation ceases also, and nothing remains but defence, i.e.,
+ the removal of the objections of those who pretend to have seen deeper
+ into the nature of things, and thereupon boldly declare freedom
+ impossible. We can only point out to them that the supposed contradiction
+ that they have discovered in it arises only from this, that in order to be
+ able to apply the law of nature to human actions, they must necessarily
+ consider man as an appearance: then when we demand of them that they
+ should also think of him qua intelligence as a thing in itself, they still
+ persist in considering him in this respect also as an appearance. In this
+ view it would no doubt be a contradiction to suppose the causality of the
+ same subject (that is, his will) to be withdrawn from all the natural laws
+ of the sensible world. But this contradiction disappears, if they would
+ only bethink themselves and admit, as is reasonable, that behind the
+ appearances there must also lie at their root (although hidden) the things
+ in themselves, and that we cannot expect the laws of these to be the same
+ as those that govern their appearances.
+ </p>
+ <p>
+ The subjective impossibility of explaining the freedom of the will is
+ identical with the impossibility of discovering and explaining an interest
+ * which man can take in the moral law. Nevertheless he does actually take
+ an interest in it, the basis of which in us we call the moral feeling,
+ which some have falsely assigned as the standard of our moral judgement,
+ whereas it must rather be viewed as the subjective effect that the law
+ exercises on the will, the objective principle of which is furnished by
+ reason alone.
+ </p>
+<pre xml:space="preserve">
+ * Interest is that by which reason becomes practical, i.e.,
+ a cause determining the will. Hence we say of rational
+ beings only that they take an interest in a thing;
+ irrational beings only feel sensual appetites. Reason takes
+ a direct interest in action then only when the universal
+ validity of its maxims is alone sufficient to determine the
+ will. Such an interest alone is pure. But if it can
+ determine the will only by means of another object of desire
+ or on the suggestion of a particular feeling of the subject,
+ then reason takes only an indirect interest in the action,
+ and, as reason by itself without experience cannot discover
+ either objects of the will or a special feeling actuating
+ it, this latter interest would only be empirical and not a
+ pure rational interest. The logical interest of reason
+ (namely, to extend its insight) is never direct, but
+ presupposes purposes for which reason is employed.
+</pre>
+ <p>
+ In order indeed that a rational being who is also affected through the
+ senses should will what reason alone directs such beings that they ought
+ to will, it is no doubt requisite that reason should have a power to
+ infuse a feeling of pleasure or satisfaction in the fulfilment of duty,
+ that is to say, that it should have a causality by which it determines the
+ sensibility according to its own principles. But it is quite impossible to
+ discern, i.e., to make it intelligible a priori, how a mere thought, which
+ itself contains nothing sensible, can itself produce a sensation of
+ pleasure or pain; for this is a particular kind of causality of which as
+ of every other causality we can determine nothing whatever a priori; we
+ must only consult experience about it. But as this cannot supply us with
+ any relation of cause and effect except between two objects of experience,
+ whereas in this case, although indeed the effect produced lies within
+ experience, yet the cause is supposed to be pure reason acting through
+ mere ideas which offer no object to experience, it follows that for us men
+ it is quite impossible to explain how and why the universality of the
+ maxim as a law, that is, morality, interests. This only is certain, that
+ it is not because it interests us that it has validity for us (for that
+ would be heteronomy and dependence of practical reason on sensibility,
+ namely, on a feeling as its principle, in which case it could never give
+ moral laws), but that it interests us because it is valid for us as men,
+ inasmuch as it had its source in our will as intelligences, in other
+ words, in our proper self, and what belongs to mere appearance is
+ necessarily subordinated by reason to the nature of the thing in itself.
+ </p>
+ <p>
+ The question then, "How a categorical imperative is possible," can be
+ answered to this extent, that we can assign the only hypothesis on which
+ it is possible, namely, the idea of freedom; and we can also discern the
+ necessity of this hypothesis, and this is sufficient for the practical
+ exercise of reason, that is, for the conviction of the validity of this
+ imperative, and hence of the moral law; but how this hypothesis itself is
+ possible can never be discerned by any human reason. On the hypothesis,
+ however, that the will of an intelligence is free, its autonomy, as the
+ essential formal condition of its determination, is a necessary
+ consequence. Moreover, this freedom of will is not merely quite possible
+ as a hypothesis (not involving any contradiction to the principle of
+ physical necessity in the connexion of the phenomena of the sensible
+ world) as speculative philosophy can show: but further, a rational being
+ who is conscious of causality through reason, that is to say, of a will
+ (distinct from desires), must of necessity make it practically, that is,
+ in idea, the condition of all his voluntary actions. But to explain how
+ pure reason can be of itself practical without the aid of any spring of
+ action that could be derived from any other source, i.e., how the mere
+ principle of the universal validity of all its maxims as laws (which would
+ certainly be the form of a pure practical reason) can of itself supply a
+ spring, without any matter (object) of the will in which one could
+ antecedently take any interest; and how it can produce an interest which
+ would be called purely moral; or in other words, how pure reason can be
+ practical- to explain this is beyond the power of human reason, and all
+ the labour and pains of seeking an explanation of it are lost.
+ </p>
+ <p>
+ It is just the same as if I sought to find out how freedom itself is
+ possible as the causality of a will. For then I quit the ground of
+ philosophical explanation, and I have no other to go upon. I might indeed
+ revel in the world of intelligences which still remains to me, but
+ although I have an idea of it which is well founded, yet I have not the
+ least knowledge of it, nor an I ever attain to such knowledge with all the
+ efforts of my natural faculty of reason. It signifies only a something
+ that remains over when I have eliminated everything belonging to the world
+ of sense from the actuating principles of my will, serving merely to keep
+ in bounds the principle of motives taken from the field of sensibility;
+ fixing its limits and showing that it does not contain all in all within
+ itself, but that there is more beyond it; but this something more I know
+ no further. Of pure reason which frames this ideal, there remains after
+ the abstraction of all matter, i.e., knowledge of objects, nothing but the
+ form, namely, the practical law of the universality of the maxims, and in
+ conformity with this conception of reason in reference to a pure world of
+ understanding as a possible efficient cause, that is a cause determining
+ the will. There must here be a total absence of springs; unless this idea
+ of an intelligible world is itself the spring, or that in which reason
+ primarily takes an interest; but to make this intelligible is precisely
+ the problem that we cannot solve.
+ </p>
+ <p>
+ Here now is the extreme limit of all moral inquiry, and it is of great
+ importance to determine it even on this account, in order that reason may
+ not on the one hand, to the prejudice of morals, seek about in the world
+ of sense for the supreme motive and an interest comprehensible but
+ empirical; and on the other hand, that it may not impotently flap its
+ wings without being able to move in the (for it) empty space of
+ transcendent concepts which we call the intelligible world, and so lose
+ itself amidst chimeras. For the rest, the idea of a pure world of
+ understanding as a system of all intelligences, and to which we ourselves
+ as rational beings belong (although we are likewise on the other side
+ members of the sensible world), this remains always a useful and
+ legitimate idea for the purposes of rational belief, although all
+ knowledge stops at its threshold, useful, namely, to produce in us a
+ lively interest in the moral law by means of the noble ideal of a
+ universal kingdom of ends in themselves (rational beings), to which we can
+ belong as members then only when we carefully conduct ourselves according
+ to the maxims of freedom as if they were laws of nature.

+ <h2>
+ CONCLUDING REMARK
+ </h2>
+ <p>
+ The speculative employment of reason with respect to nature leads to the
+ absolute necessity of some supreme cause of the world: the practical
+ employment of reason with a view to freedom leads also to absolute
+ necessity, but only of the laws of the actions of a rational being as
+ such. Now it is an essential principle of reason, however employed, to
+ push its knowledge to a consciousness of its necessity (without which it
+ would not be rational knowledge). It is, however, an equally essential
+ restriction of the same reason that it can neither discern the necessity
+ of what is or what happens, nor of what ought to happen, unless a
+ condition is supposed on which it is or happens or ought to happen. In
+ this way, however, by the constant inquiry for the condition, the
+ satisfaction of reason is only further and further postponed. Hence it
+ unceasingly seeks the unconditionally necessary and finds itself forced to
+ assume it, although without any means of making it comprehensible to
+ itself, happy enough if only it can discover a conception which agrees
+ with this assumption. It is therefore no fault in our deduction of the
+ supreme principle of morality, but an objection that should be made to
+ human reason in general, that it cannot enable us to conceive the absolute
+ necessity of an unconditional practical law (such as the categorical
+ imperative must be). It cannot be blamed for refusing to explain this
+ necessity by a condition, that is to say, by means of some interest
+ assumed as a basis, since the law would then cease to be a supreme law of
+ reason. And thus while we do not comprehend the practical unconditional
+ necessity of the moral imperative, we yet comprehend its
+ incomprehensibility, and this is all that can be fairly demanded of a
+ philosophy which strives to carry its principles up to the very limit of
+ human reason.

+We produce about two million dollars for each hour we work. The
+time it takes us, a rather conservative estimate, is fifty hours
+to get any eBook selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. Our
+projected audience is one hundred million readers. If the value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour in 2002 as we release over 100 new text
+files per month: 1240 more eBooks in 2001 for a total of 4000+
+We are already on our way to trying for 2000 more eBooks in 2002
+If they reach just 1-2% of the world's population then the total
+will reach over half a trillion eBooks given away by year's end.

+ FUNDAMENTAL PRINCIPLES OF THE METAPHYSIC OF MORALS
+
+ by Immanuel Kant
+
+ translated by Thomas Kingsmill Abbott
+
+
+PREFACE
+
+
+
+Ancient Greek philosophy was divided into three sciences: physics,
+ethics, and logic. This division is perfectly suitable to the nature
+of the thing; and the only improvement that can be made in it is to
+add the principle on which it is based, so that we may both satisfy
+ourselves of its completeness, and also be able to determine correctly
+the necessary subdivisions.
+
+All rational knowledge is either material or formal: the former
+considers some object, the latter is concerned only with the form of
+the understanding and of the reason itself, and with the universal
+laws of thought in general without distinction of its objects.
+Formal philosophy is called logic. Material philosophy, however, which has
+to do with determinate objects and the laws to which they are subject,
+is again twofold; for these laws are either laws of nature or of
+freedom. The science of the former is physics, that of the latter,
+ethics; they are also called natural philosophy and moral philosophy
+respectively.
+
+Logic cannot have any empirical part; that is, a part in which the
+universal and necessary laws of thought should rest on grounds taken
+from experience; otherwise it would not be logic, i.e., a canon for
+the understanding or the reason, valid for all thought, and capable of
+demonstration. Natural and moral philosophy, on the contrary, can each
+have their empirical part, since the former has to determine the
+laws of nature as an object of experience; the latter the laws of
+the human will, so far as it is affected by nature: the former,
+however, being laws according to which everything does happen; the
+latter, laws according to which everything ought to happen. Ethics,
+however, must also consider the conditions under which what ought to
+happen frequently does not.
+
+We may call all philosophy empirical, so far as it is based on
+grounds of experience: on the other hand, that which delivers its
+doctrines from a priori principles alone we may call pure
+philosophy. When the latter is merely formal it is logic; if it is
+restricted to definite objects of the understanding it is metaphysic.
+
+In this way there arises the idea of a twofold metaphysic- a
+metaphysic of nature and a metaphysic of morals. Physics will thus
+have an empirical and also a rational part. It is the same with
+Ethics; but here the empirical part might have the special name of
+practical anthropology, the name morality being appropriated to the
+rational part.
+
+All trades, arts, and handiworks have gained by division of
+labour, namely, when, instead of one man doing everything, each
+confines himself to a certain kind of work distinct from others in the
+treatment it requires, so as to be able to perform it with greater
+facility and in the greatest perfection. Where the different kinds
+of work are not distinguished and divided, where everyone is a
+jack-of-all-trades, there manufactures remain still in the greatest
+barbarism. It might deserve to be considered whether pure philosophy
+in all its parts does not require a man specially devoted to it, and
+whether it would not be better for the whole business of science if
+those who, to please the tastes of the public, are wont to blend the
+rational and empirical elements together, mixed in all sorts of
+proportions unknown to themselves, and who call themselves independent
+thinkers, giving the name of minute philosophers to those who apply
+themselves to the rational part only- if these, I say, were warned not
+to carry on two employments together which differ widely in the
+treatment they demand, for each of which perhaps a special talent is
+required, and the combination of which in one person only produces
+bunglers. But I only ask here whether the nature of science does not
+require that we should always carefully separate the empirical from
+the rational part, and prefix to Physics proper (or empirical physics)
+a metaphysic of nature, and to practical anthropology a metaphysic
+of morals, which must be carefully cleared of everything empirical, so
+that we may know how much can be accomplished by pure reason in both
+cases, and from what sources it draws this its a priori teaching,
+and that whether the latter inquiry is conducted by all moralists
+(whose name is legion), or only by some who feel a calling thereto.
+
+As my concern here is with moral philosophy, I limit the question
+suggested to this: Whether it is not of the utmost necessity to
+construct a pure thing which is only empirical and which belongs to
+anthropology? for that such a philosophy must be possible is evident
+from the common idea of duty and of the moral laws. Everyone must
+admit that if a law is to have moral force, i.e., to be the basis of
+an obligation, it must carry with it absolute necessity; that, for
+example, the precept, "Thou shalt not lie," is not valid for men
+alone, as if other rational beings had no need to observe it; and so
+with all the other moral laws properly so called; that, therefore, the
+basis of obligation must not be sought in the nature of man, or in the
+circumstances in the world in which he is placed, but a priori
+simply in the conception of pure reason; and although any other
+precept which is founded on principles of mere experience may be in
+certain respects universal, yet in as far as it rests even in the
+least degree on an empirical basis, perhaps only as to a motive,
+such a precept, while it may be a practical rule, can never be
+called a moral law.
+
+Thus not only are moral laws with their principles essentially
+distinguished from every other kind of practical knowledge in which
+there is anything empirical, but all moral philosophy rests wholly
+on its pure part. When applied to man, it does not borrow the least
+thing from the knowledge of man himself (anthropology), but gives laws
+a priori to him as a rational being. No doubt these laws require a
+judgement sharpened by experience, in order on the one hand to
+distinguish in what cases they are applicable, and on the other to
+procure for them access to the will of the man and effectual influence
+on conduct; since man is acted on by so many inclinations that, though
+capable of the idea of a practical pure reason, he is not so easily
+able to make it effective in concreto in his life.
+
+A metaphysic of morals is therefore indispensably necessary, not
+merely for speculative reasons, in order to investigate the sources of
+the practical principles which are to be found a priori in our reason,
+but also because morals themselves are liable to all sorts of
+corruption, as long as we are without that clue and supreme canon by
+which to estimate them correctly. For in order that an action should
+be morally good, it is not enough that it conform to the moral law,
+but it must also be done for the sake of the law, otherwise that
+conformity is only very contingent and uncertain; since a principle
+which is not moral, although it may now and then produce actions
+conformable to the law, will also often produce actions which
+contradict it. Now it is only in a pure philosophy that we can look for
+the moral law in its purity and genuineness (and, in a practical
+matter, this is of the utmost consequence): we must, therefore,
+begin with pure philosophy (metaphysic), and without it there cannot
+be any moral philosophy at all. That which mingles these pure
+principles with the empirical does not deserve the name of
+philosophy (for what distinguishes philosophy from common rational
+knowledge is that it treats in separate sciences what the latter
+only comprehends confusedly); much less does it deserve that of
+moral philosophy, since by this confusion it even spoils the purity of
+morals themselves, and counteracts its own end.
+
+Let it not be thought, however, that what is here demanded is
+already extant in the propaedeutic prefixed by the celebrated Wolf
+to his moral philosophy, namely, his so-called general practical
+philosophy, and that, therefore, we have not to strike into an
+entirely new field. Just because it was to be a general practical
+philosophy, it has not taken into consideration a will of any
+particular kind- say one which should be determined solely from a
+priori principles without any empirical motives, and which we might
+call a pure will, but volition in general, with all the actions and
+conditions which belong to it in this general signification. By this
+it is distinguished from a metaphysic of morals, just as general
+logic, which treats of the acts and canons of thought in general, is
+distinguished from transcendental philosophy, which treats of the
+particular acts and canons of pure thought, i.e., that whose
+cognitions are altogether a priori. For the metaphysic of morals has
+to examine the idea and the principles of a possible pure will, and
+not the acts and conditions of human volition generally, which for the
+most part are drawn from psychology. It is true that moral laws and
+duty are spoken of in the general moral philosophy (contrary indeed to
+all fitness). But this is no objection, for in this respect also the
+authors of that science remain true to their idea of it; they do not
+distinguish the motives which are prescribed as such by reason alone
+altogether a priori, and which are properly moral, from the
+empirical motives which the understanding raises to general
+conceptions merely by comparison of experiences; but, without noticing
+the difference of their sources, and looking on them all as
+homogeneous, they consider only their greater or less amount. It is in
+this way they frame their notion of obligation, which, though anything
+but moral, is all that can be attained in a philosophy which passes no
+judgement at all on the origin of all possible practical concepts,
+whether they are a priori, or only a posteriori.
+
+Intending to publish hereafter a metaphysic of morals, I issue in
+the first instance these fundamental principles. Indeed there is
+properly no other foundation for it than the critical examination of a
+pure practical reason; just as that of metaphysics is the critical
+examination of the pure speculative reason, already published. But
+in the first place the former is not so absolutely necessary as the
+latter, because in moral concerns human reason can easily be brought
+to a high degree of correctness and completeness, even in the
+commonest understanding, while on the contrary in its theoretic but
+pure use it is wholly dialectical; and in the second place if the
+critique of a pure practical Reason is to be complete, it must be
+possible at the same time to show its identity with the speculative
+reason in a common principle, for it can ultimately be only one and
+the same reason which has to be distinguished merely in its
+application. I could not, however, bring it to such completeness here,
+without introducing considerations of a wholly different kind, which
+would be perplexing to the reader. On this account I have adopted
+the title of Fundamental Principles of the Metaphysic of Morals
+instead of that of a Critical Examination of the pure practical
+reason.
+
+But in the third place, since a metaphysic of morals, in spite of
+the discouraging title, is yet capable of being presented in popular
+form, and one adapted to the common understanding, I find it useful to
+separate from it this preliminary treatise on its fundamental
+principles, in order that I may not hereafter have need to introduce
+these necessarily subtle discussions into a book of a more simple
+character.
+
+The present treatise is, however, nothing more than the
+investigation and establishment of the supreme principle of
+morality, and this alone constitutes a study complete in itself and
+one which ought to be kept apart from every other moral investigation.
+No doubt my conclusions on this weighty question, which has hitherto
+been very unsatisfactorily examined, would receive much light from the
+application of the same principle to the whole system, and would be
+greatly confirmed by the adequacy which it exhibits throughout; but
+I must forego this advantage, which indeed would be after all more
+gratifying than useful, since the easy applicability of a principle
+and its apparent adequacy give no very certain proof of its soundness,
+but rather inspire a certain partiality, which prevents us from
+examining and estimating it strictly in itself and without regard to
+consequences.
+
+I have adopted in this work the method which I think most
+suitable, proceeding analytically from common knowledge to the
+determination of its ultimate principle, and again descending
+synthetically from the examination of this principle and its sources
+to the common knowledge in which we find it employed. The division
+will, therefore, be as follows:
+
+
+
+1 FIRST SECTION. Transition from the common rational knowledge of
+morality to the philosophical.
+
+
+
+2 SECOND SECTION. Transition from popular moral philosophy to the
+metaphysic of morals.
+
+
+
+3 THIRD SECTION. Final step from the metaphysic of morals to the
+critique of the pure practical reason.

+Nothing can possibly be conceived in the world, or even out of it,
+which can be called good, without qualification, except a good will.
+Intelligence, wit, judgement, and the other talents of the mind,
+however they may be named, or courage, resolution, perseverance, as
+qualities of temperament, are undoubtedly good and desirable in many
+respects; but these gifts of nature may also become extremely bad
+and mischievous if the will which is to make use of them, and which,
+therefore, constitutes what is called character, is not good. It is
+the same with the gifts of fortune. Power, riches, honour, even
+health, and the general well-being and contentment with one's
+condition which is called happiness, inspire pride, and often
+presumption, if there is not a good will to correct the influence of
+these on the mind, and with this also to rectify the whole principle
+of acting and adapt it to its end. The sight of a being who is not
+adorned with a single feature of a pure and good will, enjoying
+unbroken prosperity, can never give pleasure to an impartial
+rational spectator. Thus a good will appears to constitute the
+indispensable condition even of being worthy of happiness.
+
+There are even some qualities which are of service to this good will
+itself and may facilitate its action, yet which have no intrinsic
+unconditional value, but always presuppose a good will, and this
+qualifies the esteem that we justly have for them and does not
+permit us to regard them as absolutely good. Moderation in the
+affections and passions, self-control, and calm deliberation are not
+only good in many respects, but even seem to constitute part of the
+intrinsic worth of the person; but they are far from deserving to be
+called good without qualification, although they have been so
+unconditionally praised by the ancients. For without the principles of
+a good will, they may become extremely bad, and the coolness of a
+villain not only makes him far more dangerous, but also directly makes
+him more abominable in our eyes than he would have been without it.
+
+A good will is good not because of what it performs or effects,
+not by its aptness for the attainment of some proposed end, but simply
+by virtue of the volition; that is, it is good in itself, and
+considered by itself is to be esteemed much higher than all that can
+be brought about by it in favour of any inclination, nay even of the
+sum total of all inclinations. Even if it should happen that, owing to
+special disfavour of fortune, or the niggardly provision of a
+step-motherly nature, this will should wholly lack power to accomplish
+its purpose, if with its greatest efforts it should yet achieve
+nothing, and there should remain only the good will (not, to be
+sure, a mere wish, but the summoning of all means in our power), then,
+like a jewel, it would still shine by its own light, as a thing
+which has its whole value in itself. Its usefulness or fruitlessness
+can neither add nor take away anything from this value. It would be,
+as it were, only the setting to enable us to handle it the more
+conveniently in common commerce, or to attract to it the attention
+of those who are not yet connoisseurs, but not to recommend it to true
+connoisseurs, or to determine its value.
+
+There is, however, something so strange in this idea of the absolute
+value of the mere will, in which no account is taken of its utility,
+that notwithstanding the thorough assent of even common reason to
+the idea, yet a suspicion must arise that it may perhaps really be the
+product of mere high-flown fancy, and that we may have misunderstood
+the purpose of nature in assigning reason as the governor of our will.
+Therefore we will examine this idea from this point of view.
+
+In the physical constitution of an organized being, that is, a being
+adapted suitably to the purposes of life, we assume it as a
+fundamental principle that no organ for any purpose will be found
+but what is also the fittest and best adapted for that purpose. Now in
+a being which has reason and a will, if the proper object of nature
+were its conservation, its welfare, in a word, its happiness, then
+nature would have hit upon a very bad arrangement in selecting the
+reason of the creature to carry out this purpose. For all the
+actions which the creature has to perform with a view to this purpose,
+and the whole rule of its conduct, would be far more surely prescribed
+to it by instinct, and that end would have been attained thereby
+much more certainly than it ever can be by reason. Should reason
+have been communicated to this favoured creature over and above, it
+must only have served it to contemplate the happy constitution of
+its nature, to admire it, to congratulate itself thereon, and to
+feel thankful for it to the beneficent cause, but not that it should
+subject its desires to that weak and delusive guidance and meddle
+bunglingly with the purpose of nature. In a word, nature would have
+taken care that reason should not break forth into practical exercise,
+nor have the presumption, with its weak insight, to think out for
+itself the plan of happiness, and of the means of attaining it. Nature
+would not only have taken on herself the choice of the ends, but
+also of the means, and with wise foresight would have entrusted both
+to instinct.
+
+And, in fact, we find that the more a cultivated reason applies
+itself with deliberate purpose to the enjoyment of life and happiness,
+so much the more does the man fail of true satisfaction. And from this
+circumstance there arises in many, if they are candid enough to
+confess it, a certain degree of misology, that is, hatred of reason,
+especially in the case of those who are most experienced in the use of
+it, because after calculating all the advantages they derive, I do not
+say from the invention of all the arts of common luxury, but even from
+the sciences (which seem to them to be after all only a luxury of
+the understanding), they find that they have, in fact, only brought
+more trouble on their shoulders, rather than gained in happiness;
+and they end by envying, rather than despising, the more common
+stamp of men who keep closer to the guidance of mere instinct and do
+not allow their reason much influence on their conduct. And this we
+must admit, that the judgement of those who would very much lower
+the lofty eulogies of the advantages which reason gives us in regard
+to the happiness and satisfaction of life, or who would even reduce
+them below zero, is by no means morose or ungrateful to the goodness
+with which the world is governed, but that there lies at the root of
+these judgements the idea that our existence has a different and far
+nobler end, for which, and not for happiness, reason is properly
+intended, and which must, therefore, be regarded as the supreme
+condition to which the private ends of man must, for the most part, be
+postponed.
+
+For as reason is not competent to guide the will with certainty in
+regard to its objects and the satisfaction of all our wants (which
+it to some extent even multiplies), this being an end to which an
+implanted instinct would have led with much greater certainty; and
+since, nevertheless, reason is imparted to us as a practical
+faculty, i.e., as one which is to have influence on the will,
+therefore, admitting that nature generally in the distribution of
+her capacities has adapted the means to the end, its true
+destination must be to produce a will, not merely good as a means to
+something else, but good in itself, for which reason was absolutely
+necessary. This will then, though not indeed the sole and complete
+good, must be the supreme good and the condition of every other,
+even of the desire of happiness. Under these circumstances, there is
+nothing inconsistent with the wisdom of nature in the fact that the
+cultivation of the reason, which is requisite for the first and
+unconditional purpose, does in many ways interfere, at least in this
+life, with the attainment of the second, which is always
+conditional, namely, happiness. Nay, it may even reduce it to nothing,
+without nature thereby failing of her purpose. For reason recognizes
+the establishment of a good will as its highest practical destination,
+and in attaining this purpose is capable only of a satisfaction of its
+own proper kind, namely that from the attainment of an end, which
+end again is determined by reason only, notwithstanding that this
+may involve many a disappointment to the ends of inclination.
+
+We have then to develop the notion of a will which deserves to be
+highly esteemed for itself and is good without a view to anything
+further, a notion which exists already in the sound natural
+understanding, requiring rather to be cleared up than to be taught,
+and which in estimating the value of our actions always takes the
+first place and constitutes the condition of all the rest. In order to
+do this, we will take the notion of duty, which includes that of a
+good will, although implying certain subjective restrictions and
+hindrances. These, however, far from concealing it, or rendering it
+unrecognizable, rather bring it out by contrast and make it shine
+forth so much the brighter.
+
+I omit here all actions which are already recognized as inconsistent
+with duty, although they may be useful for this or that purpose, for
+with these the question whether they are done from duty cannot arise
+at all, since they even conflict with it. I also set aside those
+actions which really conform to duty, but to which men have no
+direct inclination, performing them because they are impelled
+thereto by some other inclination. For in this case we can readily
+distinguish whether the action which agrees with duty is done from
+duty, or from a selfish view. It is much harder to make this
+distinction when the action accords with duty and the subject has
+besides a direct inclination to it. For example, it is always a matter
+of duty that a dealer should not over charge an inexperienced
+purchaser; and wherever there is much commerce the prudent tradesman
+does not overcharge, but keeps a fixed price for everyone, so that a
+child buys of him as well as any other. Men are thus honestly
+served; but this is not enough to make us believe that the tradesman
+has so acted from duty and from principles of honesty: his own
+advantage required it; it is out of the question in this case to
+suppose that he might besides have a direct inclination in favour of
+the buyers, so that, as it were, from love he should give no advantage
+to one over another. Accordingly the action was done neither from duty
+nor from direct inclination, but merely with a selfish view.
+
+On the other hand, it is a duty to maintain one's life; and, in
+addition, everyone has also a direct inclination to do so. But on this
+account the often anxious care which most men take for it has no
+intrinsic worth, and their maxim has no moral import. They preserve
+their life as duty requires, no doubt, but not because duty
+requires. On the other hand, if adversity and hopeless sorrow have
+completely taken away the relish for life; if the unfortunate one,
+strong in mind, indignant at his fate rather than desponding or
+dejected, wishes for death, and yet preserves his life without
+loving it- not from inclination or fear, but from duty- then his maxim
+has a moral worth.
+
+To be beneficent when we can is a duty; and besides this, there
+are many minds so sympathetically constituted that, without any
+other motive of vanity or self-interest, they find a pleasure in
+spreading joy around them and can take delight in the satisfaction
+of others so far as it is their own work. But I maintain that in
+such a case an action of this kind, however proper, however amiable it
+may be, has nevertheless no true moral worth, but is on a level with
+other inclinations, e.g., the inclination to honour, which, if it is
+happily directed to that which is in fact of public utility and
+accordant with duty and consequently honourable, deserves praise and
+encouragement, but not esteem. For the maxim lacks the moral import,
+namely, that such actions be done from duty, not from inclination. Put
+the case that the mind of that philanthropist were clouded by sorrow
+of his own, extinguishing all sympathy with the lot of others, and
+that, while he still has the power to benefit others in distress, he
+is not touched by their trouble because he is absorbed with his own;
+and now suppose that he tears himself out of this dead
+insensibility, and performs the action without any inclination to
+it, but simply from duty, then first has his action its genuine
+moral worth. Further still; if nature has put little sympathy in the
+heart of this or that man; if he, supposed to be an upright man, is by
+temperament cold and indifferent to the sufferings of others,
+perhaps because in respect of his own he is provided with the
+special gift of patience and fortitude and supposes, or even requires,
+that others should have the same- and such a man would certainly not
+be the meanest product of nature- but if nature had not specially
+framed him for a philanthropist, would he not still find in himself
+a source from whence to give himself a far higher worth than that of a
+good-natured temperament could be? Unquestionably. It is just in
+this that the moral worth of the character is brought out which is
+incomparably the highest of all, namely, that he is beneficent, not
+from inclination, but from duty.
+
+To secure one's own happiness is a duty, at least indirectly; for
+discontent with one's condition, under a pressure of many anxieties
+and amidst unsatisfied wants, might easily become a great temptation
+to transgression of duty. But here again, without looking to duty, all
+men have already the strongest and most intimate inclination to
+happiness, because it is just in this idea that all inclinations are
+combined in one total. But the precept of happiness is often of such a
+sort that it greatly interferes with some inclinations, and yet a
+man cannot form any definite and certain conception of the sum of
+satisfaction of all of them which is called happiness. It is not
+then to be wondered at that a single inclination, definite both as
+to what it promises and as to the time within which it can be
+gratified, is often able to overcome such a fluctuating idea, and that
+a gouty patient, for instance, can choose to enjoy what he likes,
+and to suffer what he may, since, according to his calculation, on
+this occasion at least, he has not sacrificed the enjoyment of the
+present moment to a possibly mistaken expectation of a happiness which
+is supposed to be found in health. But even in this case, if the
+general desire for happiness did not influence his will, and supposing
+that in his particular case health was not a necessary element in this
+calculation, there yet remains in this, as in all other cases, this
+law, namely, that he should promote his happiness not from inclination
+but from duty, and by this would his conduct first acquire true
+moral worth.
+
+It is in this manner, undoubtedly, that we are to understand those
+passages of Scripture also in which we are commanded to love our
+neighbour, even our enemy. For love, as an affection, cannot be
+commanded, but beneficence for duty's sake may; even though we are not
+impelled to it by any inclination- nay, are even repelled by a natural
+and unconquerable aversion. This is practical love and not
+pathological- a love which is seated in the will, and not in the
+propensions of sense- in principles of action and not of tender
+sympathy; and it is this love alone which can be commanded.
+
+The second proposition is: That an action done from duty derives its
+moral worth, not from the purpose which is to be attained by it, but
+from the maxim by which it is determined, and therefore does not
+depend on the realization of the object of the action, but merely on
+the principle of volition by which the action has taken place, without
+regard to any object of desire. It is clear from what precedes that
+the purposes which we may have in view in our actions, or their
+effects regarded as ends and springs of the will, cannot give to
+actions any unconditional or moral worth. In what, then, can their
+worth lie, if it is not to consist in the will and in reference to its
+expected effect? It cannot lie anywhere but in the principle of the
+will without regard to the ends which can be attained by the action.
+For the will stands between its a priori principle, which is formal,
+and its a posteriori spring, which is material, as between two roads,
+and as it must be determined by something, it follows that it must be
+determined by the formal principle of volition when an action is done
+from duty, in which case every material principle has been withdrawn
+from it.
+
+The third proposition, which is a consequence of the two
+preceding, I would express thus: Duty is the necessity of acting from
+respect for the law. I may have inclination for an object as the
+effect of my proposed action, but I cannot have respect for it, just
+for this reason, that it is an effect and not an energy of will.
+Similarly I cannot have respect for inclination, whether my own or
+another's; I can at most, if my own, approve it; if another's,
+sometimes even love it; i.e., look on it as favourable to my own
+interest. It is only what is connected with my will as a principle, by
+no means as an effect- what does not subserve my inclination, but
+overpowers it, or at least in case of choice excludes it from its
+calculation- in other words, simply the law of itself, which can be an
+object of respect, and hence a command. Now an action done from duty
+must wholly exclude the influence of inclination and with it every
+object of the will, so that nothing remains which can determine the
+will except objectively the law, and subjectively pure respect for
+this practical law, and consequently the maxim * that I should follow
+this law even to the thwarting of all my inclinations.
+
+
+
+* A maxim is the subjective principle of volition. The objective
+principle (i.e., that which would also serve subjectively as a
+practical principle to all rational beings if reason had full power
+over the faculty of desire) is the practical law.
+
+
+
+Thus the moral worth of an action does not lie in the effect
+expected from it, nor in any principle of action which requires to
+borrow its motive from this expected effect. For all these effects-
+agreeableness of one's condition and even the promotion of the
+happiness of others- could have been also brought about by other
+causes, so that for this there would have been no need of the will
+of a rational being; whereas it is in this alone that the supreme
+and unconditional good can be found. The pre-eminent good which we
+call moral can therefore consist in nothing else than the conception
+of law in itself, which certainly is only possible in a rational
+being, in so far as this conception, and not the expected effect,
+determines the will. This is a good which is already present in the
+person who acts accordingly, and we have not to wait for it to
+appear first in the result. *
+
+
+
+* It might be here objected to me that I take refuge behind the
+word respect in an obscure feeling, instead of giving a distinct
+solution of the question by a concept of the reason. But although
+respect is a feeling, it is not a feeling received through
+influence, but is self-wrought by a rational concept, and,
+therefore, is specifically distinct from all feelings of the former
+kind, which may be referred either to inclination or fear, What I
+recognise immediately as a law for me, I recognise with respect.
+This merely signifies the consciousness that my will is subordinate to
+a law, without the intervention of other influences on my sense. The
+immediate determination of the will by the law, and the
+consciousness of this, is called respect, so that this is regarded
+as an effect of the law on the subject, and not as the cause of it.
+Respect is properly the conception of a worth which thwarts my
+self-love. Accordingly it is something which is considered neither
+as an object of inclination nor of fear, although it has something
+analogous to both. The object of respect is the law only, and that the
+law which we impose on ourselves and yet recognise as necessary in
+itself. As a law, we are subjected too it without consulting
+self-love; as imposed by us on ourselves, it is a result of our
+will. In the former aspect it has an analogy to fear, in the latter to
+inclination. Respect for a person is properly only respect for the law
+(of honesty, etc.) of which he gives us an example. Since we also look
+on the improvement of our talents as a duty, we consider that we see
+in a person of talents, as it were, the example of a law (viz., to
+become like him in this by exercise), and this constitutes our
+respect. All so-called moral interest consists simply in respect for
+the law.
+
+
+
+But what sort of law can that be, the conception of which must
+determine the will, even without paying any regard to the effect
+expected from it, in order that this will may be called good
+absolutely and without qualification? As I have deprived the will of
+every impulse which could arise to it from obedience to any law, there
+remains nothing but the universal conformity of its actions to law
+in general, which alone is to serve the will as a principle, i.e., I
+am never to act otherwise than so that I could also will that my maxim
+should become a universal law. Here, now, it is the simple
+conformity to law in general, without assuming any particular law
+applicable to certain actions, that serves the will as its principle
+and must so serve it, if duty is not to be a vain delusion and a
+chimerical notion. The common reason of men in its practical
+judgements perfectly coincides with this and always has in view the
+principle here suggested. Let the question be, for example: May I when
+in distress make a promise with the intention not to keep it? I
+readily distinguish here between the two significations which the
+question may have: Whether it is prudent, or whether it is right, to
+make a false promise? The former may undoubtedly often be the case. I see
+clearly indeed that it is not enough to extricate myself from a
+present difficulty by means of this subterfuge, but it must be well
+considered whether there may not hereafter spring from this lie much
+greater inconvenience than that from which I now free myself, and
+as, with all my supposed cunning, the consequences cannot be so easily
+foreseen but that credit once lost may be much more injurious to me
+than any mischief which I seek to avoid at present, it should be
+considered whether it would not be more prudent to act herein
+according to a universal maxim and to make it a habit to promise
+nothing except with the intention of keeping it. But it is soon
+clear to me that such a maxim will still only be based on the fear
+of consequences. Now it is a wholly different thing to be truthful
+from duty and to be so from apprehension of injurious consequences. In
+the first case, the very notion of the action already implies a law
+for me; in the second case, I must first look about elsewhere to see
+what results may be combined with it which would affect myself. For to
+deviate from the principle of duty is beyond all doubt wicked; but
+to be unfaithful to my maxim of prudence may often be very
+advantageous to me, although to abide by it is certainly safer. The
+shortest way, however, and an unerring one, to discover the answer
+to this question whether a lying promise is consistent with duty, is
+to ask myself, "Should I be content that my maxim (to extricate myself
+from difficulty by a false promise) should hold good as a universal
+law, for myself as well as for others?" and should I be able to say
+to myself, "Every one may make a deceitful promise when he finds
+himself in a difficulty from which he cannot otherwise extricate
+himself?" Then I presently become aware that while I can will the lie,
+I can by no means will that lying should be a universal law. For
+with such a law there would be no promises at all, since it would be
+in vain to allege my intention in regard to my future actions to those
+who would not believe this allegation, or if they over hastily did
+so would pay me back in my own coin. Hence my maxim, as soon as it
+should be made a universal law, would necessarily destroy itself.
+
+I do not, therefore, need any far-reaching penetration to discern
+what I have to do in order that my will may be morally good.
+Inexperienced in the course of the world, incapable of being
+prepared for all its contingencies, I only ask myself: Canst thou also
+will that thy maxim should be a universal law? If not, then it must be
+rejected, and that not because of a disadvantage accruing from it to
+myself or even to others, but because it cannot enter as a principle
+into a possible universal legislation, and reason extorts from me
+immediate respect for such legislation. I do not indeed as yet discern
+on what this respect is based (this the philosopher may inquire),
+but at least I understand this, that it is an estimation of the
+worth which far outweighs all worth of what is recommended by
+inclination, and that the necessity of acting from pure respect for
+the practical law is what constitutes duty, to which every other
+motive must give place, because it is the condition of a will being
+good in itself, and the worth of such a will is above everything.
+
+Thus, then, without quitting the moral knowledge of common human
+reason, we have arrived at its principle. And although, no doubt,
+common men do not conceive it in such an abstract and universal
+form, yet they always have it really before their eyes and use it as
+the standard of their decision. Here it would be easy to show how,
+with this compass in hand, men are well able to distinguish, in
+every case that occurs, what is good, what bad, conformably to duty or
+inconsistent with it, if, without in the least teaching them
+anything new, we only, like Socrates, direct their attention to the
+principle they themselves employ; and that, therefore, we do not
+need science and philosophy to know what we should do to be honest and
+good, yea, even wise and virtuous. Indeed we might well have
+conjectured beforehand that the knowledge of what every man is bound
+to do, and therefore also to know, would be within the reach of
+every man, even the commonest. Here we cannot forbear admiration
+when we see how great an advantage the practical judgement has over
+the theoretical in the common understanding of men. In the latter,
+if common reason ventures to depart from the laws of experience and
+from the perceptions of the senses, it falls into mere
+inconceivabilities and self-contradictions, at least into a chaos of
+uncertainty, obscurity, and instability. But in the practical sphere
+it is just when the common understanding excludes all sensible springs
+from practical laws that its power of judgement begins to show
+itself to advantage. It then becomes even subtle, whether it be that
+it chicanes with its own conscience or with other claims respecting
+what is to be called right, or whether it desires for its own
+instruction to determine honestly the worth of actions; and, in the
+latter case, it may even have as good a hope of hitting the mark as
+any philosopher whatever can promise himself. Nay, it is almost more
+sure of doing so, because the philosopher cannot have any other
+principle, while he may easily perplex his judgement by a multitude of
+considerations foreign to the matter, and so turn aside from the right
+way. Would it not therefore be wiser in moral concerns to acquiesce in
+the judgement of common reason, or at most only to call in
+philosophy for the purpose of rendering the system of morals more
+complete and intelligible, and its rules more convenient for use
+(especially for disputation), but not so as to draw off the common
+understanding from its happy simplicity, or to bring it by means of
+philosophy into a new path of inquiry and instruction?
+
+Innocence is indeed a glorious thing; only, on the other hand, it is
+very sad that it cannot well maintain itself and is easily seduced. On
+this account even wisdom- which otherwise consists more in conduct
+than in knowledge- yet has need of science, not in order to learn from
+it, but to secure for its precepts admission and permanence. Against
+all the commands of duty which reason represents to man as so
+deserving of respect, he feels in himself a powerful counterpoise in
+his wants and inclinations, the entire satisfaction of which he sums
+up under the name of happiness. Now reason issues its commands
+unyieldingly, without promising anything to the inclinations, and,
+as it were, with disregard and contempt for these claims, which are so
+impetuous, and at the same time so plausible, and which will not allow
+themselves to be suppressed by any command. Hence there arises a
+natural dialectic, i.e., a disposition, to argue against these
+strict laws of duty and to question their validity, or at least
+their purity and strictness; and, if possible, to make them more
+accordant with our wishes and inclinations, that is to say, to corrupt
+them at their very source, and entirely to destroy their worth- a
+thing which even common practical reason cannot ultimately call good.
+
+Thus is the common reason of man compelled to go out of its
+sphere, and to take a step into the field of a practical philosophy,
+not to satisfy any speculative want (which never occurs to it as
+long as it is content to be mere sound reason), but even on
+practical grounds, in order to attain in it information and clear
+instruction respecting the source of its principle, and the correct
+determination of it in opposition to the maxims which are based on
+wants and inclinations, so that it may escape from the perplexity of
+opposite claims and not run the risk of losing all genuine moral
+principles through the equivocation into which it easily falls.
+Thus, when practical reason cultivates itself, there insensibly arises
+in it a dialetic which forces it to seek aid in philosophy, just as
+happens to it in its theoretic use; and in this case, therefore, as
+well as in the other, it will find rest nowhere but in a thorough
+critical examination of our reason.
+
+SEC_2
+
+ SECOND SECTION
+
+
+
+ TRANSITION FROM POPULAR MORAL PHILOSOPHY
+
+ TO THE METAPHYSIC OF MORALS
+
+
+
+If we have hitherto drawn our notion of duty from the common use
+of our practical reason, it is by no means to be inferred that we have
+treated it as an empirical notion. On the contrary, if we attend to
+the experience of men's conduct, we meet frequent and, as we ourselves
+allow, just complaints that one cannot find a single certain example
+of the disposition to act from pure duty. Although many things are
+done in conformity with what duty prescribes, it is nevertheless
+always doubtful whether they are done strictly from duty, so as to
+have a moral worth. Hence there have at all times been philosophers
+who have altogether denied that this disposition actually exists at
+all in human actions, and have ascribed everything to a more or less
+refined self-love. Not that they have on that account questioned the
+soundness of the conception of morality; on the contrary, they spoke
+with sincere regret of the frailty and corruption of human nature,
+which, though noble enough to take its rule an idea so worthy of
+respect, is yet weak to follow it and employs reason which ought to
+give it the law only for the purpose of providing for the interest
+of the inclinations, whether singly or at the best in the greatest
+possible harmony with one another.
+
+In fact, it is absolutely impossible to make out by experience
+with complete certainty a single case in which the maxim of an action,
+however right in itself, rested simply on moral grounds and on the
+conception of duty. Sometimes it happens that with the sharpest
+self-examination we can find nothing beside the moral principle of
+duty which could have been powerful enough to move us to this or
+that action and to so great a sacrifice; yet we cannot from this infer
+with certainty that it was not really some secret impulse of
+self-love, under the false appearance of duty, that was the actual
+determining cause of the will. We like them to flatter ourselves by
+falsely taking credit for a more noble motive; whereas in fact we
+can never, even by the strictest examination, get completely behind
+the secret springs of action; since, when the question is of moral
+worth, it is not with the actions which we see that we are
+concerned, but with those inward principles of them which we do not
+see.
+
+Moreover, we cannot better serve the wishes of those who ridicule
+all morality as a mere chimera of human imagination over stepping
+itself from vanity, than by conceding to them that notions of duty
+must be drawn only from experience (as from indolence, people are
+ready to think is also the case with all other notions); for or is
+to prepare for them a certain triumph. I am willing to admit out of
+love of humanity that even most of our actions are correct, but if
+we look closer at them we everywhere come upon the dear self which
+is always prominent, and it is this they have in view and not the
+strict command of duty which would often require self-denial.
+Without being an enemy of virtue, a cool observer, one that does not
+mistake the wish for good, however lively, for its reality, may
+sometimes doubt whether true virtue is actually found anywhere in
+the world, and this especially as years increase and the judgement
+is partly made wiser by experience and partly, also, more acute in
+observation. This being so, nothing can secure us from falling away
+altogether from our ideas of duty, or maintain in the soul a
+well-grounded respect for its law, but the clear conviction that
+although there should never have been actions which really sprang from
+such pure sources, yet whether this or that takes place is not at
+all the question; but that reason of itself, independent on all
+experience, ordains what ought to take place, that accordingly actions
+of which perhaps the world has hitherto never given an example, the
+feasibility even of which might be very much doubted by one who founds
+everything on experience, are nevertheless inflexibly commanded by
+reason; that, e.g., even though there might never yet have been a
+sincere friend, yet not a whit the less is pure sincerity in
+friendship required of every man, because, prior to all experience,
+this duty is involved as duty in the idea of a reason determining
+the will by a priori principles.
+
+When we add further that, unless we deny that the notion of morality
+has any truth or reference to any possible object, we must admit
+that its law must be valid, not merely for men but for all rational
+creatures generally, not merely under certain contingent conditions or
+with exceptions but with absolute necessity, then it is clear that
+no experience could enable us to infer even the possibility of such
+apodeictic laws. For with what right could we bring into unbounded
+respect as a universal precept for every rational nature that which
+perhaps holds only under the contingent conditions of humanity? Or how
+could laws of the determination of our will be regarded as laws of the
+determination of the will of rational beings generally, and for us
+only as such, if they were merely empirical and did not take their
+origin wholly a priori from pure but practical reason?
+
+Nor could anything be more fatal to morality than that we should
+wish to derive it from examples. For every example of it that is set
+before me must be first itself tested by principles of morality,
+whether it is worthy to serve as an original example, i.e., as a
+pattern; but by no means can it authoritatively furnish the conception
+of morality. Even the Holy One of the Gospels must first be compared
+with our ideal of moral perfection before we can recognise Him as
+such; and so He says of Himself, "Why call ye Me (whom you see)
+good; none is good (the model of good) but God only (whom ye do not
+see)?" But whence have we the conception of God as the supreme good?
+Simply from the idea of moral perfection, which reason frames a priori
+and connects inseparably with the notion of a free will. Imitation
+finds no place at all in morality, and examples serve only for
+encouragement, i.e., they put beyond doubt the feasibility of what the
+law commands, they make visible that which the practical rule
+expresses more generally, but they can never authorize us to set aside
+the true original which lies in reason and to guide ourselves by
+examples.
+
+If then there is no genuine supreme principle of morality but what
+must rest simply on pure reason, independent of all experience, I
+think it is not necessary even to put the question whether it is
+good to exhibit these concepts in their generality (in abstracto) as
+they are established a priori along with the principles belonging to
+them, if our knowledge is to be distinguished from the vulgar and to
+be called philosophical.
+
+In our times indeed this might perhaps be necessary; for if we
+collected votes whether pure rational knowledge separated from
+everything empirical, that is to say, metaphysic of morals, or whether
+popular practical philosophy is to be preferred, it is easy to guess
+which side would preponderate.
+
+This descending to popular notions is certainly very commendable, if
+the ascent to the principles of pure reason has first taken place
+and been satisfactorily accomplished. This implies that we first found
+ethics on metaphysics, and then, when it is firmly established,
+procure a hearing for it by giving it a popular character. But it is
+quite absurd to try to be popular in the first inquiry, on which the
+soundness of the principles depends. It is not only that this
+proceeding can never lay claim to the very rare merit of a true
+philosophical popularity, since there is no art in being
+intelligible if one renounces all thoroughness of insight; but also it
+produces a disgusting medley of compiled observations and
+half-reasoned principles. Shallow pates enjoy this because it can be
+used for every-day chat, but the sagacious find in it only
+confusion, and being unsatisfied and unable to help themselves, they
+turn away their eyes, while philosophers, who see quite well through
+this delusion, are little listened to when they call men off for a
+time from this pretended popularity, in order that they might be
+rightfully popular after they have attained a definite insight.
+
+We need only look at the attempts of moralists in that favourite
+fashion, and we shall find at one time the special constitution of
+human nature (including, however, the idea of a rational nature
+generally), at one time perfection, at another happiness, here moral
+sense, there fear of God. a little of this, and a little of that, in
+marvellous mixture, without its occurring to them to ask whether the
+principles of morality are to be sought in the knowledge of human
+nature at all (which we can have only from experience); or, if this is
+not so, if these principles are to be found altogether a priori,
+free from everything empirical, in pure rational concepts only and
+nowhere else, not even in the smallest degree; then rather to adopt
+the method of making this a separate inquiry, as pure practical
+philosophy, or (if one may use a name so decried) as metaphysic of
+morals, * to bring it by itself to completeness, and to require the
+public, which wishes for popular treatment, to await the issue of this
+undertaking.
+
+
+
+* Just as pure mathematics are distinguished from applied, pure
+logic from applied, so if we choose we may also distinguish pure
+philosophy of morals (metaphysic) from applied (viz., applied to human
+nature). By this designation we are also at once reminded that moral
+principles are not based on properties of human nature, but must
+subsist a priori of themselves, while from such principles practical
+rules must be capable of being deduced for every rational nature,
+and accordingly for that of man.
+
+
+
+Such a metaphysic of morals, completely isolated, not mixed with any
+anthropology, theology, physics, or hyperphysics, and still less
+with occult qualities (which we might call hypophysical), is not
+only an indispensable substratum of all sound theoretical knowledge of
+duties, but is at the same time a desideratum of the highest
+importance to the actual fulfilment of their precepts. For the pure
+conception of duty, unmixed with any foreign addition of empirical
+attractions, and, in a word, the conception of the moral law,
+exercises on the human heart, by way of reason alone (which first
+becomes aware with this that it can of itself be practical), an
+influence so much more powerful than all other springs * which may be
+derived from the field of experience, that, in the consciousness of
+its worth, it despises the latter, and can by degrees become their
+master; whereas a mixed ethics, compounded partly of motives drawn
+from feelings and inclinations, and partly also of conceptions of
+reason, must make the mind waver between motives which cannot be
+brought under any principle, which lead to good only by mere
+accident and very often also to evil.
+
+
+
+* I have a letter from the late excellent Sulzer, in which he asks
+me what can be the reason that moral instruction, although containing
+much that is convincing for the reason, yet accomplishes so little? My
+answer was postponed in order that I might make it complete. But it is
+simply this: that the teachers themselves have not got their own
+notions clear, and when they endeavour to make up for this by raking
+up motives of moral goodness from every quarter, trying to make
+their physic right strong, they spoil it. For the commonest
+understanding shows that if we imagine, on the one hand, an act of
+honesty done with steadfast mind, apart from every view to advantage
+of any kind in this world or another, and even under the greatest
+temptations of necessity or allurement, and, on the other hand, a
+similar act which was affected, in however low a degree, by a
+foreign motive, the former leaves far behind and eclipses the
+second; it elevates the soul and inspires the wish to be able to act
+in like manner oneself. Even moderately young children feel this
+impression, ana one should never represent duties to them in any other
+light.
+
+
+
+From what has been said, it is clear that all moral conceptions have
+their seat and origin completely a priori in the reason, and that,
+moreover, in the commonest reason just as truly as in that which is in
+the highest degree speculative; that they cannot be obtained by
+abstraction from any empirical, and therefore merely contingent,
+knowledge; that it is just this purity of their origin that makes them
+worthy to serve as our supreme practical principle, and that just in
+proportion as we add anything empirical, we detract from their genuine
+influence and from the absolute value of actions; that it is not
+only of the greatest necessity, in a purely speculative point of view,
+but is also of the greatest practical importance, to derive these
+notions and laws from pure reason, to present them pure and unmixed,
+and even to determine the compass of this practical or pure rational
+knowledge, i.e., to determine the whole faculty of pure practical
+reason; and, in doing so, we must not make its principles dependent on
+the particular nature of human reason, though in speculative
+philosophy this may be permitted, or may even at times be necessary;
+but since moral laws ought to hold good for every rational creature,
+we must derive them from the general concept of a rational being. In
+this way, although for its application to man morality has need of
+anthropology, yet, in the first instance, we must treat it
+independently as pure philosophy, i.e., as metaphysic, complete in
+itself (a thing which in such distinct branches of science is easily
+done); knowing well that unless we are in possession of this, it would
+not only be vain to determine the moral element of duty in right
+actions for purposes of speculative criticism, but it would be
+impossible to base morals on their genuine principles, even for common
+practical purposes, especially of moral instruction, so as to
+produce pure moral dispositions, and to engraft them on men's minds to
+the promotion of the greatest possible good in the world.
+
+But in order that in this study we may not merely advance by the
+natural steps from the common moral judgement (in this case very
+worthy of respect) to the philosophical, as has been already done, but
+also from a popular philosophy, which goes no further than it can
+reach by groping with the help of examples, to metaphysic (which
+does allow itself to be checked by anything empirical and, as it
+must measure the whole extent of this kind of rational knowledge, goes
+as far as ideal conceptions, where even examples fail us), we must
+follow and clearly describe the practical faculty of reason, from
+the general rules of its determination to the point where the notion
+of duty springs from it.
+
+Everything in nature works according to laws. Rational beings
+alone have the faculty of acting according to the conception of
+laws, that is according to principles, i.e., have a will. Since the
+deduction of actions from principles requires reason, the will is
+nothing but practical reason. If reason infallibly determines the
+will, then the actions of such a being which are recognised as
+objectively necessary are subjectively necessary also, i.e., the
+will is a faculty to choose that only which reason independent of
+inclination recognises as practically necessary, i.e., as good. But if
+reason of itself does not sufficiently determine the will, if the
+latter is subject also to subjective conditions (particular
+impulses) which do not always coincide with the objective
+conditions; in a word, if the will does not in itself completely
+accord with reason (which is actually the case with men), then the
+actions which objectively are recognised as necessary are subjectively
+contingent, and the determination of such a will according to
+objective laws is obligation, that is to say, the relation of the
+objective laws to a will that is not thoroughly good is conceived as
+the determination of the will of a rational being by principles of
+reason, but which the will from its nature does not of necessity
+follow.
+
+The conception of an objective principle, in so far as it is
+obligatory for a will, is called a command (of reason), and the
+formula of the command is called an imperative.
+
+All imperatives are expressed by the word ought [or shall], and
+thereby indicate the relation of an objective law of reason to a will,
+which from its subjective constitution is not necessarily determined
+by it (an obligation). They say that something would be good to do
+or to forbear, but they say it to a will which does not always do a
+thing because it is conceived to be good to do it. That is practically
+good, however, which determines the will by means of the conceptions
+of reason, and consequently not from subjective causes, but
+objectively, that is on principles which are valid for every
+rational being as such. It is distinguished from the pleasant, as that
+which influences the will only by means of sensation from merely
+subjective causes, valid only for the sense of this or that one, and
+not as a principle of reason, which holds for every one. *
+
+
+
+* The dependence of the desires on sensations is called
+inclination, and this accordingly always indicates a want. The
+dependence of a contingently determinable will on principles of reason
+is called an interest. This therefore, is found only in the case of
+a dependent will which does not always of itself conform to reason; in
+the Divine will we cannot conceive any interest. But the human will
+can also take an interest in a thing without therefore acting from
+interest. The former signifies the practical interest in the action,
+the latter the pathological in the object of the action. The former
+indicates only dependence of the will on principles of reason in
+themselves; the second, dependence on principles of reason for the
+sake of inclination, reason supplying only the practical rules how the
+requirement of the inclination may be satisfied. In the first case the
+action interests me; in the second the object of the action (because
+it is pleasant to me). We have seen in the first section that in an
+action done from duty we must look not to the interest in the
+object, but only to that in the action itself, and in its rational
+principle (viz., the law).
+
+
+
+A perfectly good will would therefore be equally subject to
+objective laws (viz., laws of good), but could not be conceived as
+obliged thereby to act lawfully, because of itself from its subjective
+constitution it can only be determined by the conception of good.
+Therefore no imperatives hold for the Divine will, or in general for a
+holy will; ought is here out of place, because the volition is already
+of itself necessarily in unison with the law. Therefore imperatives
+are only formulae to express the relation of objective laws of all
+volition to the subjective imperfection of the will of this or that
+rational being, e.g., the human will.
+
+Now all imperatives command either hypothetically or
+categorically. The former represent the practical necessity of a
+possible action as means to something else that is willed (or at least
+which one might possibly will). The categorical imperative would be
+that which represented an action as necessary of itself without
+reference to another end, i.e., as objectively necessary.
+
+Since every practical law represents a possible action as good
+and, on this account, for a subject who is practically determinable by
+reason, necessary, all imperatives are formulae determining an
+action which is necessary according to the principle of a will good in
+some respects. If now the action is good only as a means to
+something else, then the imperative is hypothetical; if it is
+conceived as good in itself and consequently as being necessarily
+the principle of a will which of itself conforms to reason, then it is
+categorical.
+
+Thus the imperative declares what action possible by me would be
+good and presents the practical rule in relation to a will which
+does not forthwith perform an action simply because it is good,
+whether because the subject does not always know that it is good, or
+because, even if it know this, yet its maxims might be opposed to
+the objective principles of practical reason.
+
+Accordingly the hypothetical imperative only says that the action is
+good for some purpose, possible or actual. In the first case it is a
+problematical, in the second an assertorial practical principle. The
+categorical imperative which declares an action to be objectively
+necessary in itself without reference to any purpose, i.e., without
+any other end, is valid as an apodeictic (practical) principle.
+
+Whatever is possible only by the power of some rational being may
+also be conceived as a possible purpose of some will; and therefore
+the principles of action as regards the means necessary to attain some
+possible purpose are in fact infinitely numerous. All sciences have
+a practical part, consisting of problems expressing that some end is
+possible for us and of imperatives directing how it may be attained.
+These may, therefore, be called in general imperatives of skill.
+Here there is no question whether the end is rational and good, but
+only what one must do in order to attain it. The precepts for the
+physician to make his patient thoroughly healthy, and for a poisoner
+to ensure certain death, are of equal value in this respect, that each
+serves to effect its purpose perfectly. Since in early youth it cannot
+be known what ends are likely to occur to us in the course of life,
+parents seek to have their children taught a great many things, and
+provide for their skill in the use of means for all sorts of arbitrary
+ends, of none of which can they determine whether it may not perhaps
+hereafter be an object to their pupil, but which it is at all events
+possible that he might aim at; and this anxiety is so great that
+they commonly neglect to form and correct their judgement on the value
+of the things which may be chosen as ends.
+
+There is one end, however, which may be assumed to be actually
+such to all rational beings (so far as imperatives apply to them,
+viz., as dependent beings), and, therefore, one purpose which they not
+merely may have, but which we may with certainty assume that they
+all actually have by a natural necessity, and this is happiness. The
+hypothetical imperative which expresses the practical necessity of
+an action as means to the advancement of happiness is assertorial.
+We are not to present it as necessary for an uncertain and merely
+possible purpose, but for a purpose which we may presuppose with
+certainty and a priori in every man, because it belongs to his
+being. Now skill in the choice of means to his own greatest well-being
+may be called prudence, * in the narrowest sense. And thus the
+imperative which refers to the choice of means to one's own happiness,
+i.e., the precept of prudence, is still always hypothetical; the
+action is not commanded absolutely, but only as means to another
+purpose.
+
+
+
+* The word prudence is taken in two senses: in the one it may bear
+the name of knowledge of the world, in the other that of private
+prudence. The former is a man's ability to influence others so as to
+use them for his own purposes. The latter is the sagacity to combine
+all these purposes for his own lasting benefit. This latter is
+properly that to which the value even of the former is reduced, and
+when a man is prudent in the former sense, but not in the latter, we
+might better say of him that he is clever and cunning, but, on the
+whole, imprudent.
+
+
+
+Finally, there is an imperative which commands a certain conduct
+immediately, without having as its condition any other purpose to be
+attained by it. This imperative is categorical. It concerns not the
+matter of the action, or its intended result, but its form and the
+principle of which it is itself a result; and what is essentially good
+in it consists in the mental disposition, let the consequence be
+what it may. This imperative may be called that of morality.
+
+There is a marked distinction also between the volitions on these
+three sorts of principles in the dissimilarity of the obligation of
+the will. In order to mark this difference more clearly, I think
+they would be most suitably named in their order if we said they are
+either rules of skill, or counsels of prudence, or commands (laws)
+of morality. For it is law only that involves the conception of an
+unconditional and objective necessity, which is consequently
+universally valid; and commands are laws which must be obeyed, that
+is, must be followed, even in opposition to inclination. Counsels,
+indeed, involve necessity, but one which can only hold under a
+contingent subjective condition, viz., they depend on whether this
+or that man reckons this or that as part of his happiness; the
+categorical imperative, on the contrary, is not limited by any
+condition, and as being absolutely, although practically, necessary,
+may be quite properly called a command. We might also call the first
+kind of imperatives technical (belonging to art), the second
+pragmatic * (to welfare), the third moral (belonging to free conduct
+generally, that is, to morals).
+
+
+
+* It seems to me that the proper signification of the word
+pragmatic may be most accurately defined in this way. For sanctions
+are called pragmatic which flow properly not from the law of the
+states as necessary enactments, but from precaution for the general
+welfare. A history is composed pragmatically when it teaches prudence,
+i.e., instructs the world how it can provide for its interests better,
+or at least as well as, the men of former time.
+
+
+
+Now arises the question, how are all these imperatives possible?
+This question does not seek to know how we can conceive the
+accomplishment of the action which the imperative ordains, but
+merely how we can conceive the obligation of the will which the
+imperative expresses. No special explanation is needed to show how
+an imperative of skill is possible. Whoever wills the end, wills
+also (so far as reason decides his conduct) the means in his power
+which are indispensably necessary thereto. This proposition is, as
+regards the volition, analytical; for, in willing an object as my
+effect, there is already thought the causality of myself as an
+acting cause, that is to say, the use of the means; and the imperative
+educes from the conception of volition of an end the conception of
+actions necessary to this end. Synthetical propositions must no
+doubt be employed in defining the means to a proposed end; but they do
+not concern the principle, the act of the will, but the object and its
+realization. E.g., that in order to bisect a line on an unerring
+principle I must draw from its extremities two intersecting arcs; this
+no doubt is taught by mathematics only in synthetical propositions;
+but if I know that it is only by this process that the intended
+operation can be performed, then to say that, if I fully will the
+operation, I also will the action required for it, is an analytical
+proposition; for it is one and the same thing to conceive something as
+an effect which I can produce in a certain way, and to conceive myself
+as acting in this way.
+
+If it were only equally easy to give a definite conception of
+happiness, the imperatives of prudence would correspond exactly with
+those of skill, and would likewise be analytical. For in this case
+as in that, it could be said: "Whoever wills the end, wills also
+(according to the dictate of reason necessarily) the indispensable
+means thereto which are in his power." But, unfortunately, the
+notion of happiness is so indefinite that although every man wishes to
+attain it, yet he never can say definitely and consistently what it is
+that he really wishes and wills. The reason of this is that all the
+elements which belong to the notion of happiness are altogether
+empirical, i.e., they must be borrowed from experience, and
+nevertheless the idea of happiness requires an absolute whole, a
+maximum of welfare in my present and all future circumstances. Now
+it is impossible that the most clear-sighted and at the same time most
+powerful being (supposed finite) should frame to himself a definite
+conception of what he really wills in this. Does he will riches, how
+much anxiety, envy, and snares might he not thereby draw upon his
+shoulders? Does he will knowledge and discernment, perhaps it might
+prove to be only an eye so much the sharper to show him so much the
+more fearfully the evils that are now concealed from him, and that
+cannot be avoided, or to impose more wants on his desires, which
+already give him concern enough. Would he have long life? who
+guarantees to him that it would not be a long misery? would he at
+least have health? how often has uneasiness of the body restrained
+from excesses into which perfect health would have allowed one to
+fall? and so on. In short, he is unable, on any principle, to
+determine with certainty what would make him truly happy; because to
+do so he would need to be omniscient. We cannot therefore act on any
+definite principles to secure happiness, but only on empirical
+counsels, e.g. of regimen, frugality, courtesy, reserve, etc., which
+experience teaches do, on the average, most promote well-being.
+Hence it follows that the imperatives of prudence do not, strictly
+speaking, command at all, that is, they cannot present actions
+objectively as practically necessary; that they are rather to be
+regarded as counsels (consilia) than precepts precepts of reason, that
+the problem to determine certainly and universally what action would
+promote the happiness of a rational being is completely insoluble, and
+consequently no imperative respecting it is possible which should,
+in the strict sense, command to do what makes happy; because happiness
+is not an ideal of reason but of imagination, resting solely on
+empirical grounds, and it is vain to expect that these should define
+an action by which one could attain the totality of a series of
+consequences which is really endless. This imperative of prudence
+would however be an analytical proposition if we assume that the means
+to happiness could be certainly assigned; for it is distinguished from
+the imperative of skill only by this, that in the latter the end is
+merely possible, in the former it is given; as however both only
+ordain the means to that which we suppose to be willed as an end, it
+follows that the imperative which ordains the willing of the means
+to him who wills the end is in both cases analytical. Thus there is no
+difficulty in regard to the possibility of an imperative of this
+kind either.
+
+On the other hand, the question how the imperative of morality is
+possible, is undoubtedly one, the only one, demanding a solution, as
+this is not at all hypothetical, and the objective necessity which
+it presents cannot rest on any hypothesis, as is the case with the
+hypothetical imperatives. Only here we must never leave out of
+consideration that we cannot make out by any example, in other words
+empirically, whether there is such an imperative at all, but it is
+rather to be feared that all those which seem to be categorical may
+yet be at bottom hypothetical. For instance, when the precept is:
+"Thou shalt not promise deceitfully"; and it is assumed that the
+necessity of this is not a mere counsel to avoid some other evil, so
+that it should mean: "Thou shalt not make a lying promise, lest if
+it become known thou shouldst destroy thy credit," but that an
+action of this kind must be regarded as evil in itself, so that the
+imperative of the prohibition is categorical; then we cannot show with
+certainty in any example that the will was determined merely by the
+law, without any other spring of action, although it may appear to
+be so. For it is always possible that fear of disgrace, perhaps also
+obscure dread of other dangers, may have a secret influence on the
+will. Who can prove by experience the non-existence of a cause when
+all that experience tells us is that we do not perceive it? But in
+such a case the so-called moral imperative, which as such appears to
+be categorical and unconditional, would in reality be only a pragmatic
+precept, drawing our attention to our own interests and merely
+teaching us to take these into consideration.
+
+We shall therefore have to investigate a priori the possibility of a
+categorical imperative, as we have not in this case the advantage of
+its reality being given in experience, so that [the elucidation of]
+its possibility should be requisite only for its explanation, not
+for its establishment. In the meantime it may be discerned
+beforehand that the categorical imperative alone has the purport of
+a practical law; all the rest may indeed be called principles of the
+will but not laws, since whatever is only necessary for the attainment
+of some arbitrary purpose may be considered as in itself contingent,
+and we can at any time be free from the precept if we give up the
+purpose; on the contrary, the unconditional command leaves the will no
+liberty to choose the opposite; consequently it alone carries with
+it that necessity which we require in a law.
+
+Secondly, in the case of this categorical imperative or law of
+morality, the difficulty (of discerning its possibility) is a very
+profound one. It is an a priori synthetical practical proposition; *
+and as there is so much difficulty in discerning the possibility of
+speculative propositions of this kind, it may readily be supposed that
+the difficulty will be no less with the practical.
+
+
+
+* I connect the act with the will without presupposing any
+condition resulting from any inclination, but a priori, and
+therefore necessarily (though only objectively, i.e., assuming the
+idea of a reason possessing full power over all subjective motives).
+This is accordingly a practical proposition which does not deduce
+the willing of an action by mere analysis from another already
+presupposed (for we have not such a perfect will), but connects it
+immediately with the conception of the will of a rational being, as
+something not contained in it.
+
+
+
+In this problem we will first inquire whether the mere conception of
+a categorical imperative may not perhaps supply us also with the
+formula of it, containing the proposition which alone can be a
+categorical imperative; for even if we know the tenor of such an
+absolute command, yet how it is possible will require further
+special and laborious study, which we postpone to the last section.
+
+When I conceive a hypothetical imperative, in general I do not
+know beforehand what it will contain until I am given the condition.
+But when I conceive a categorical imperative, I know at once what it
+contains. For as the imperative contains besides the law only the
+necessity that the maxims * shall conform to this law, while the law
+contains no conditions restricting it, there remains nothing but the
+general statement that the maxim of the action should conform to a
+universal law, and it is this conformity alone that the imperative
+properly represents as necessary.
+
+
+
+* A maxim is a subjective principle of action, and must be
+distinguished from the objective principle, namely, practical law. The
+former contains the practical rule set by reason according to the
+conditions of the subject (often its ignorance or its inclinations),
+so that it is the principle on which the subject acts; but the law
+is the objective principle valid for every rational being, and is
+the principle on which it ought to act that is an imperative.
+
+
+
+There is therefore but one categorical imperative, namely, this: Act
+only on that maxim whereby thou canst at the same time will that it
+should become a universal law.
+
+Now if all imperatives of duty can be deduced from this one
+imperative as from their principle, then, although it should remain
+undecided what is called duty is not merely a vain notion, yet at
+least we shall be able to show what we understand by it and what
+this notion means.
+
+Since the universality of the law according to which effects are
+produced constitutes what is properly called nature in the most
+general sense (as to form), that is the existence of things so far
+as it is determined by general laws, the imperative of duty may be
+expressed thus: Act as if the maxim of thy action were to become by
+thy will a universal law of nature.
+
+We will now enumerate a few duties, adopting the usual division of
+them into duties to ourselves and ourselves and to others, and into
+perfect and imperfect duties. *
+
+
+
+* It must be noted here that I reserve the division of duties for a
+future metaphysic of morals; so that I give it here only as an
+arbitrary one (in order to arrange my examples). For the rest, I
+understand by a perfect duty one that admits no exception in favour of
+inclination and then I have not merely external but also internal
+perfect duties. This is contrary to the use of the word adopted in the
+schools; but I do not intend to justify there, as it is all one for my
+purpose whether it is admitted or not.
+
+
+
+1. A man reduced to despair by a series of misfortunes feels wearied
+of life, but is still so far in possession of his reason that he can
+ask himself whether it would not be contrary to his duty to himself to
+take his own life. Now he inquires whether the maxim of his action
+could become a universal law of nature. His maxim is: "From
+self-love I adopt it as a principle to shorten my life when its longer
+duration is likely to bring more evil than satisfaction." It is
+asked then simply whether this principle founded on self-love can
+become a universal law of nature. Now we see at once that a system
+of nature of which it should be a law to destroy life by means of
+the very feeling whose special nature it is to impel to the
+improvement of life would contradict itself and, therefore, could
+not exist as a system of nature; hence that maxim cannot possibly
+exist as a universal law of nature and, consequently, would be
+wholly inconsistent with the supreme principle of all duty.
+
+2. Another finds himself forced by necessity to borrow money. He
+knows that he will not be able to repay it, but sees also that nothing
+will be lent to him unless he promises stoutly to repay it in a
+definite time. He desires to make this promise, but he has still so
+much conscience as to ask himself: "Is it not unlawful and
+inconsistent with duty to get out of a difficulty in this way?"
+Suppose however that he resolves to do so: then the maxim of his
+action would be expressed thus: "When I think myself in want of money,
+I will borrow money and promise to repay it, although I know that I
+never can do so." Now this principle of self-love or of one's own
+advantage may perhaps be consistent with my whole future welfare;
+but the question now is, "Is it right?" I change then the suggestion
+of self-love into a universal law, and state the question thus: "How
+would it be if my maxim were a universal law?" Then I see at once that
+it could never hold as a universal law of nature, but would
+necessarily contradict itself. For supposing it to be a universal
+law that everyone when he thinks himself in a difficulty should be
+able to promise whatever he pleases, with the purpose of not keeping
+his promise, the promise itself would become impossible, as well as
+the end that one might have in view in it, since no one would consider
+that anything was promised to him, but would ridicule all such
+statements as vain pretences.
+
+3. A third finds in himself a talent which with the help of some
+culture might make him a useful man in many respects. But he finds
+himself in comfortable circumstances and prefers to indulge in
+pleasure rather than to take pains in enlarging and improving his
+happy natural capacities. He asks, however, whether his maxim of
+neglect of his natural gifts, besides agreeing with his inclination to
+indulgence, agrees also with what is called duty. He sees then that
+a system of nature could indeed subsist with such a universal law
+although men (like the South Sea islanders) should let their talents
+rest and resolve to devote their lives merely to idleness,
+amusement, and propagation of their species- in a word, to
+enjoyment; but he cannot possibly will that this should be a universal
+law of nature, or be implanted in us as such by a natural instinct.
+For, as a rational being, he necessarily wills that his faculties be
+developed, since they serve him and have been given him, for all sorts
+of possible purposes.
+
+4. A fourth, who is in prosperity, while he sees that others have to
+contend with great wretchedness and that he could help them, thinks:
+"What concern is it of mine? Let everyone be as happy as Heaven
+pleases, or as he can make himself; I will take nothing from him nor
+even envy him, only I do not wish to contribute anything to his
+welfare or to his assistance in distress!" Now no doubt if such a mode
+of thinking were a universal law, the human race might very well
+subsist and doubtless even better than in a state in which everyone
+talks of sympathy and good-will, or even takes care occasionally to
+put it into practice, but, on the other side, also cheats when he can,
+betrays the rights of men, or otherwise violates them. But although it
+is possible that a universal law of nature might exist in accordance
+with that maxim, it is impossible to will that such a principle should
+have the universal validity of a law of nature. For a will which
+resolved this would contradict itself, inasmuch as many cases might
+occur in which one would have need of the love and sympathy of others,
+and in which, by such a law of nature, sprung from his own will, he
+would deprive himself of all hope of the aid he desires.
+
+These are a few of the many actual duties, or at least what we
+regard as such, which obviously fall into two classes on the one
+principle that we have laid down. We must be able to will that a maxim
+of our action should be a universal law. This is the canon of the
+moral appreciation of the action generally. Some actions are of such a
+character that their maxim cannot without contradiction be even
+conceived as a universal law of nature, far from it being possible
+that we should will that it should be so. In others this intrinsic
+impossibility is not found, but still it is impossible to will that
+their maxim should be raised to the universality of a law of nature,
+since such a will would contradict itself It is easily seen that the
+former violate strict or rigorous (inflexible) duty; the latter only
+laxer (meritorious) duty. Thus it has been completely shown how all
+duties depend as regards the nature of the obligation (not the
+object of the action) on the same principle.
+
+If now we attend to ourselves on occasion of any transgression of
+duty, we shall find that we in fact do not will that our maxim
+should be a universal law, for that is impossible for us; on the
+contrary, we will that the opposite should remain a universal law,
+only we assume the liberty of making an exception in our own favour or
+(just for this time only) in favour of our inclination. Consequently
+if we considered all cases from one and the same point of view,
+namely, that of reason, we should find a contradiction in our own
+will, namely, that a certain principle should be objectively necessary
+as a universal law, and yet subjectively should not be universal,
+but admit of exceptions. As however we at one moment regard our action
+from the point of view of a will wholly conformed to reason, and
+then again look at the same action from the point of view of a will
+affected by inclination, there is not really any contradiction, but an
+antagonism of inclination to the precept of reason, whereby the
+universality of the principle is changed into a mere generality, so
+that the practical principle of reason shall meet the maxim half
+way. Now, although this cannot be justified in our own impartial
+judgement, yet it proves that we do really recognise the validity of
+the categorical imperative and (with all respect for it) only allow
+ourselves a few exceptions, which we think unimportant and forced from
+us.
+
+We have thus established at least this much, that if duty is a
+conception which is to have any import and real legislative
+authority for our actions, it can only be expressed in categorical and
+not at all in hypothetical imperatives. We have also, which is of
+great importance, exhibited clearly and definitely for every practical
+application the content of the categorical imperative, which must
+contain the principle of all duty if there is such a thing at all.
+We have not yet, however, advanced so far as to prove a priori that
+there actually is such an imperative, that there is a practical law
+which commands absolutely of itself and without any other impulse, and
+that the following of this law is duty.
+
+With the view of attaining to this, it is of extreme importance to
+remember that we must not allow ourselves to think of deducing the
+reality of this principle from the particular attributes of human
+nature. For duty is to be a practical, unconditional necessity of
+action; it must therefore hold for all rational beings (to whom an
+imperative can apply at all), and for this reason only be also a law
+for all human wills. On the contrary, whatever is deduced from the
+particular natural characteristics of humanity, from certain
+feelings and propensions, nay, even, if possible, from any
+particular tendency proper to human reason, and which need not
+necessarily hold for the will of every rational being; this may indeed
+supply us with a maxim, but not with a law; with a subjective
+principle on which we may have a propension and inclination to act,
+but not with an objective principle on which we should be enjoined
+to act, even though all our propensions, inclinations, and natural
+dispositions were opposed to it. In fact, the sublimity and
+intrinsic dignity of the command in duty are so much the more evident,
+the less the subjective impulses favour it and the more they oppose
+it, without being able in the slightest degree to weaken the
+obligation of the law or to diminish its validity.
+
+Here then we see philosophy brought to a critical position, since it
+has to be firmly fixed, notwithstanding that it has nothing to support
+it in heaven or earth. Here it must show its purity as absolute
+director of its own laws, not the herald of those which are
+whispered to it by an implanted sense or who knows what tutelary
+nature. Although these may be better than nothing, yet they can
+never afford principles dictated by reason, which must have their
+source wholly a priori and thence their commanding authority,
+expecting everything from the supremacy of the law and the due respect
+for it, nothing from inclination, or else condemning the man to
+self-contempt and inward abhorrence.
+
+Thus every empirical element is not only quite incapable of being an
+aid to the principle of morality, but is even highly prejudicial to
+the purity of morals, for the proper and inestimable worth of an
+absolutely good will consists just in this, that the principle of
+action is free from all influence of contingent grounds, which alone
+experience can furnish. We cannot too much or too often repeat our
+warning against this lax and even mean habit of thought which seeks
+for its principle amongst empirical motives and laws; for human reason
+in its weariness is glad to rest on this pillow, and in a dream of
+sweet illusions (in which, instead of Juno, it embraces a cloud) it
+substitutes for morality a bastard patched up from limbs of various
+derivation, which looks like anything one chooses to see in it, only
+not like virtue to one who has once beheld her in her true form. *
+
+
+
+* To behold virtue in her proper form is nothing else but to
+contemplate morality stripped of all admixture of sensible things
+and of every spurious ornament of reward or self-love. How much she
+then eclipses everything else that appears charming to the affections,
+every one may readily perceive with the least exertion of his
+reason, if it be not wholly spoiled for abstraction.
+
+
+
+The question then is this: "Is it a necessary law for all rational
+beings that they should always judge of their actions by maxims of
+which they can themselves will that they should serve as universal
+laws?" If it is so, then it must be connected (altogether a priori)
+with the very conception of the will of a rational being generally.
+But in order to discover this connexion we must, however
+reluctantly, take a step into metaphysic, although into a domain of it
+which is distinct from speculative philosophy, namely, the
+metaphysic of morals. In a practical philosophy, where it is not the
+reasons of what happens that we have to ascertain, but the laws of
+what ought to happen, even although it never does, i.e., objective
+practical laws, there it is not necessary to inquire into the
+reasons why anything pleases or displeases, how the pleasure of mere
+sensation differs from taste, and whether the latter is distinct
+from a general satisfaction of reason; on what the feeling of pleasure
+or pain rests, and how from it desires and inclinations arise, and
+from these again maxims by the co-operation of reason: for all this
+belongs to an empirical psychology, which would constitute the
+second part of physics, if we regard physics as the philosophy of
+nature, so far as it is based on empirical laws. But here we are
+concerned with objective practical laws and, consequently, with the
+relation of the will to itself so far as it is determined by reason
+alone, in which case whatever has reference to anything empirical is
+necessarily excluded; since if reason of itself alone determines the
+conduct (and it is the possibility of this that we are now
+investigating), it must necessarily do so a priori.
+
+The will is conceived as a faculty of determining oneself to
+action in accordance with the conception of certain laws. And such a
+faculty can be found only in rational beings. Now that which serves
+the will as the objective ground of its self-determination is the end,
+and, if this is assigned by reason alone, it must hold for all
+rational beings. On the other hand, that which merely contains the
+ground of possibility of the action of which the effect is the end,
+this is called the means. The subjective ground of the desire is the
+spring, the objective ground of the volition is the motive; hence
+the distinction between subjective ends which rest on springs, and
+objective ends which depend on motives valid for every rational being.
+Practical principles are formal when they abstract from all subjective
+ends; they are material when they assume these, and therefore
+particular springs of action. The ends which a rational being proposes
+to himself at pleasure as effects of his actions (material ends) are
+all only relative, for it is only their relation to the particular
+desires of the subject that gives them their worth, which therefore
+cannot furnish principles universal and necessary for all rational
+beings and for every volition, that is to say practical laws. Hence
+all these relative ends can give rise only to hypothetical
+imperatives.
+
+Supposing, however, that there were something whose existence has in
+itself an absolute worth, something which, being an end in itself,
+could be a source of definite laws; then in this and this alone
+would lie the source of a possible categorical imperative, i.e., a
+practical law.
+
+Now I say: man and generally any rational being exists as an end
+in himself, not merely as a means to be arbitrarily used by this or
+that will, but in all his actions, whether they concern himself or
+other rational beings, must be always regarded at the same time as
+an end. All objects of the inclinations have only a conditional worth,
+for if the inclinations and the wants founded on them did not exist,
+then their object would be without value. But the inclinations,
+themselves being sources of want, are so far from having an absolute
+worth for which they should be desired that on the contrary it must be
+the universal wish of every rational being to be wholly free from
+them. Thus the worth of any object which is to be acquired by our
+action is always conditional. Beings whose existence depends not on
+our will but on nature's, have nevertheless, if they are irrational
+beings, only a relative value as means, and are therefore called
+things; rational beings, on the contrary, are called persons,
+because their very nature points them out as ends in themselves,
+that is as something which must not be used merely as means, and so
+far therefore restricts freedom of action (and is an object of
+respect). These, therefore, are not merely subjective ends whose
+existence has a worth for us as an effect of our action, but objective
+ends, that is, things whose existence is an end in itself; an end
+moreover for which no other can be substituted, which they should
+subserve merely as means, for otherwise nothing whatever would possess
+absolute worth; but if all worth were conditioned and therefore
+contingent, then there would be no supreme practical principle of
+reason whatever.
+
+If then there is a supreme practical principle or, in respect of the
+human will, a categorical imperative, it must be one which, being
+drawn from the conception of that which is necessarily an end for
+everyone because it is an end in itself, constitutes an objective
+principle of will, and can therefore serve as a universal practical
+law. The foundation of this principle is: rational nature exists as an
+end in itself. Man necessarily conceives his own existence as being
+so; so far then this is a subjective principle of human actions. But
+every other rational being regards its existence similarly, just on
+the same rational principle that holds for me: * so that it is at the
+same time an objective principle, from which as a supreme practical
+law all laws of the will must be capable of being deduced. Accordingly
+the practical imperative will be as follows: So act as to treat
+humanity, whether in thine own person or in that of any other, in
+every case as an end withal, never as means only. We will now
+inquire whether this can be practically carried out.
+
+
+
+* This proposition is here stated as a postulate. The ground of it
+will be found in the concluding section.
+
+
+
+To abide by the previous examples:
+
+Firstly, under the head of necessary duty to oneself: He who
+contemplates suicide should ask himself whether his action can be
+consistent with the idea of humanity as an end in itself. If he
+destroys himself in order to escape from painful circumstances, he
+uses a person merely as a mean to maintain a tolerable condition up to
+the end of life. But a man is not a thing, that is to say, something
+which can be used merely as means, but must in all his actions be
+always considered as an end in himself. I cannot, therefore, dispose
+in any way of a man in my own person so as to mutilate him, to
+damage or kill him. (It belongs to ethics proper to define this
+principle more precisely, so as to avoid all misunderstanding, e.
+g., as to the amputation of the limbs in order to preserve myself,
+as to exposing my life to danger with a view to preserve it, etc. This
+question is therefore omitted here.)
+
+Secondly, as regards necessary duties, or those of strict
+obligation, towards others: He who is thinking of making a lying
+promise to others will see at once that he would be using another
+man merely as a mean, without the latter containing at the same time
+the end in himself. For he whom I propose by such a promise to use for
+my own purposes cannot possibly assent to my mode of acting towards
+him and, therefore, cannot himself contain the end of this action.
+This violation of the principle of humanity in other men is more
+obvious if we take in examples of attacks on the freedom and
+property of others. For then it is clear that he who transgresses
+the rights of men intends to use the person of others merely as a
+means, without considering that as rational beings they ought always
+to be esteemed also as ends, that is, as beings who must be capable of
+containing in themselves the end of the very same action. *
+
+
+
+* Let it not be thought that the common "quod tibi non vis fieri,
+etc." could serve here as the rule or principle. For it is only a
+deduction from the former, though with several limitations; it
+cannot be a universal law, for it does not contain the principle of
+duties to oneself, nor of the duties of benevolence to others (for
+many a one would gladly consent that others should not benefit him,
+provided only that he might be excused from showing benevolence to
+them), nor finally that of duties of strict obligation to one another,
+for on this principle the criminal might argue against the judge who
+punishes him, and so on.
+
+
+
+Thirdly, as regards contingent (meritorious) duties to oneself: It
+is not enough that the action does not violate humanity in our own
+person as an end in itself, it must also harmonize with it. Now
+there are in humanity capacities of greater perfection, which belong
+to the end that nature has in view in regard to humanity in
+ourselves as the subject: to neglect these might perhaps be consistent
+with the maintenance of humanity as an end in itself, but not with the
+advancement of this end.
+
+Fourthly, as regards meritorious duties towards others: The
+natural end which all men have is their own happiness. Now humanity
+might indeed subsist, although no one should contribute anything to
+the happiness of others, provided he did not intentionally withdraw
+anything from it; but after all this would only harmonize negatively
+not positively with humanity as an end in itself, if every one does
+not also endeavour, as far as in him lies, to forward the ends of
+others. For the ends of any subject which is an end in himself ought
+as far as possible to be my ends also, if that conception is to have
+its full effect with me.
+
+This principle, that humanity and generally every rational nature is
+an end in itself (which is the supreme limiting condition of every
+man's freedom of action), is not borrowed from experience, firstly,
+because it is universal, applying as it does to all rational beings
+whatever, and experience is not capable of determining anything
+about them; secondly, because it does not present humanity as an end
+to men (subjectively), that is as an object which men do of themselves
+actually adopt as an end; but as an objective end, which must as a law
+constitute the supreme limiting condition of all our subjective
+ends, let them be what we will; it must therefore spring from pure
+reason. In fact the objective principle of all practical legislation
+lies (according to the first principle) in the rule and its form of
+universality which makes it capable of being a law (say, e. g., a
+law of nature); but the subjective principle is in the end; now by the
+second principle the subject of all ends is each rational being,
+inasmuch as it is an end in itself. Hence follows the third
+practical principle of the will, which is the ultimate condition of
+its harmony with universal practical reason, viz.: the idea of the
+will of every rational being as a universally legislative will.
+
+On this principle all maxims are rejected which are inconsistent
+with the will being itself universal legislator. Thus the will is
+not subject simply to the law, but so subject that it must be regarded
+as itself giving the law and, on this ground only, subject to the
+law (of which it can regard itself as the author).
+
+In the previous imperatives, namely, that based on the conception of
+the conformity of actions to general laws, as in a physical system
+of nature, and that based on the universal prerogative of rational
+beings as ends in themselves- these imperatives, just because they
+were conceived as categorical, excluded from any share in their
+authority all admixture of any interest as a spring of action; they
+were, however, only assumed to be categorical, because such an
+assumption was necessary to explain the conception of duty. But we
+could not prove independently that there are practical propositions
+which command categorically, nor can it be proved in this section; one
+thing, however, could be done, namely, to indicate in the imperative
+itself, by some determinate expression, that in the case of volition
+from duty all interest is renounced, which is the specific criterion
+of categorical as distinguished from hypothetical imperatives. This is
+done in the present (third) formula of the principle, namely, in the
+idea of the will of every rational being as a universally
+legislating will.
+
+For although a will which is subject to laws may be attached to this
+law by means of an interest, yet a will which is itself a supreme
+lawgiver so far as it is such cannot possibly depend on any
+interest, since a will so dependent would itself still need another
+law restricting the interest of its self-love by the condition that it
+should be valid as universal law.
+
+Thus the principle that every human will is a will which in all
+its maxims gives universal laws, * provided it be otherwise
+justified, would be very well adapted to be the categorical
+imperative, in this respect, namely, that just because of the idea
+of universal legislation it is not based on interest, and therefore it
+alone among all possible imperatives can be unconditional. Or still
+better, converting the proposition, if there is a categorical
+imperative (i.e., a law for the will of every rational being), it
+can only command that everything be done from maxims of one's will
+regarded as a will which could at the same time will that it should
+itself give universal laws, for in that case only the practical
+principle and the imperative which it obeys are unconditional, since
+they cannot be based on any interest.
+
+
+
+* I may be excused from adducing examples to elucidate this
+principle, as those which have already been used to elucidate the
+categorical imperative and its formula would all serve for the like
+purpose here.
+
+
+
+Looking back now on all previous attempts to discover the
+principle of morality, we need not wonder why they all failed. It
+was seen that man was bound to laws by duty, but it was not observed
+that the laws to which he is subject are only those of his own giving,
+though at the same time they are universal, and that he is only
+bound to act in conformity with his own will; a will, however, which
+is designed by nature to give universal laws. For when one has
+conceived man only as subject to a law (no matter what), then this law
+required some interest, either by way of attraction or constraint,
+since it did not originate as a law from his own will, but this will
+was according to a law obliged by something else to act in a certain
+manner. Now by this necessary consequence all the labour spent in
+finding a supreme principle of duty was irrevocably lost. For men
+never elicited duty, but only a necessity of acting from a certain
+interest. Whether this interest was private or otherwise, in any
+case the imperative must be conditional and could not by any means
+be capable of being a moral command. I will therefore call this the
+principle of autonomy of the will, in contrast with every other
+which I accordingly reckon as heteronomy.
+
+The conception of the will of every rational being as one which must
+consider itself as giving in all the maxims of its will universal
+laws, so as to judge itself and its actions from this point of view-
+this conception leads to another which depends on it and is very
+fruitful, namely that of a kingdom of ends.
+
+By a kingdom I understand the union of different rational beings
+in a system by common laws. Now since it is by laws that ends are
+determined as regards their universal validity, hence, if we
+abstract from the personal differences of rational beings and likewise
+from all the content of their private ends, we shall be able to
+conceive all ends combined in a systematic whole (including both
+rational beings as ends in themselves, and also the special ends which
+each may propose to himself), that is to say, we can conceive a
+kingdom of ends, which on the preceding principles is possible.
+
+For all rational beings come under the law that each of them must
+treat itself and all others never merely as means, but in every case
+at the same time as ends in themselves. Hence results a systematic
+union of rational being by common objective laws, i.e., a kingdom
+which may be called a kingdom of ends, since what these laws have in
+view is just the relation of these beings to one another as ends and
+means. It is certainly only an ideal.
+
+A rational being belongs as a member to the kingdom of ends when,
+although giving universal laws in it, he is also himself subject to
+these laws. He belongs to it as sovereign when, while giving laws,
+he is not subject to the will of any other.
+
+A rational being must always regard himself as giving laws either as
+member or as sovereign in a kingdom of ends which is rendered possible
+by the freedom of will. He cannot, however, maintain the latter
+position merely by the maxims of his will, but only in case he is a
+completely independent being without wants and with unrestricted power
+adequate to his will.
+
+Morality consists then in the reference of all action to the
+legislation which alone can render a kingdom of ends possible. This
+legislation must be capable of existing in every rational being and of
+emanating from his will, so that the principle of this will is never
+to act on any maxim which could not without contradiction be also a
+universal law and, accordingly, always so to act that the will could
+at the same time regard itself as giving in its maxims universal laws.
+If now the maxims of rational beings are not by their own nature
+coincident with this objective principle, then the necessity of acting
+on it is called practical necessitation, i.e., duty. Duty does not
+apply to the sovereign in the kingdom of ends, but it does to every
+member of it and to all in the same degree.
+
+The practical necessity of acting on this principle, i.e., duty,
+does not rest at all on feelings, impulses, or inclinations, but
+solely on the relation of rational beings to one another, a relation
+in which the will of a rational being must always be regarded as
+legislative, since otherwise it could not be conceived as an end in
+itself. Reason then refers every maxim of the will, regarding it as
+legislating universally, to every other will and also to every
+action towards oneself; and this not on account of any other practical
+motive or any future advantage, but from the idea of the dignity of
+a rational being, obeying no law but that which he himself also gives.
+
+In the kingdom of ends everything has either value or dignity.
+Whatever has a value can be replaced by something else which is
+equivalent; whatever, on the other hand, is above all value, and
+therefore admits of no equivalent, has a dignity.
+
+Whatever has reference to the general inclinations and wants of
+mankind has a market value; whatever, without presupposing a want,
+corresponds to a certain taste, that is to a satisfaction in the
+mere purposeless play of our faculties, has a fancy value; but that
+which constitutes the condition under which alone anything can be an
+end in itself, this has not merely a relative worth, i.e., value,
+but an intrinsic worth, that is, dignity.
+
+Now morality is the condition under which alone a rational being can
+be an end in himself, since by this alone is it possible that he
+should be a legislating member in the kingdom of ends. Thus
+morality, and humanity as capable of it, is that which alone has
+dignity. Skill and diligence in labour have a market value; wit,
+lively imagination, and humour, have fancy value; on the other hand,
+fidelity to promises, benevolence from principle (not from
+instinct), have an intrinsic worth. Neither nature nor art contains
+anything which in default of these it could put in their place, for
+their worth consists not in the effects which spring from them, not in
+the use and advantage which they secure, but in the disposition of
+mind, that is, the maxims of the will which are ready to manifest
+themselves in such actions, even though they should not have the
+desired effect. These actions also need no recommendation from any
+subjective taste or sentiment, that they may be looked on with
+immediate favour and satisfaction: they need no immediate propension
+or feeling for them; they exhibit the will that performs them as an
+object of an immediate respect, and nothing but reason is required
+to impose them on the will; not to flatter it into them, which, in the
+case of duties, would be a contradiction. This estimation therefore
+shows that the worth of such a disposition is dignity, and places it
+infinitely above all value, with which it cannot for a moment be
+brought into comparison or competition without as it were violating
+its sanctity.
+
+What then is it which justifies virtue or the morally good
+disposition, in making such lofty claims? It is nothing less than
+the privilege it secures to the rational being of participating in the
+giving of universal laws, by which it qualifies him to be a member
+of a possible kingdom of ends, a privilege to which he was already
+destined by his own nature as being an end in himself and, on that
+account, legislating in the kingdom of ends; free as regards all
+laws of physical nature, and obeying those only which he himself
+gives, and by which his maxims can belong to a system of universal
+law, to which at the same time he submits himself. For nothing has any
+worth except what the law assigns it. Now the legislation itself which
+assigns the worth of everything must for that very reason possess
+dignity, that is an unconditional incomparable worth; and the word
+respect alone supplies a becoming expression for the esteem which a
+rational being must have for it. Autonomy then is the basis of the
+dignity of human and of every rational nature.
+
+The three modes of presenting the principle of morality that have
+been adduced are at bottom only so many formulae of the very same law,
+and each of itself involves the other two. There is, however, a
+difference in them, but it is rather subjectively than objectively
+practical, intended namely to bring an idea of the reason nearer to
+intuition (by means of a certain analogy) and thereby nearer to
+feeling. All maxims, in fact, have:
+
+1. A form, consisting in universality; and in this view the
+formula of the moral imperative is expressed thus, that the maxims
+must be so chosen as if they were to serve as universal laws of
+nature.
+
+2. A matter, namely, an end, and here the formula says that the
+rational being, as it is an end by its own nature and therefore an end
+in itself, must in every maxim serve as the condition limiting all
+merely relative and arbitrary ends.
+
+3. A complete characterization of all maxims by means of that
+formula, namely, that all maxims ought by their own legislation to
+harmonize with a possible kingdom of ends as with a kingdom of
+nature. * There is a progress here in the order of the categories of
+unity of the form of the will (its universality), plurality of the
+matter (the objects, i.e., the ends), and totality of the system of
+these. In forming our moral judgement of actions, it is better to
+proceed always on the strict method and start from the general formula
+of the categorical imperative: Act according to a maxim which can at
+the same time make itself a universal law. If, however, we wish to
+gain an entrance for the moral law, it is very useful to bring one and
+the same action under the three specified conceptions, and thereby
+as far as possible to bring it nearer to intuition.
+
+
+
+* Teleology considers nature as a kingdom of ends; ethics regards a
+possible kingdom of ends as a kingdom nature. In the first case, the
+kingdom of ends is a theoretical idea, adopted to explain what
+actually is. In the latter it is a practical idea, adopted to bring
+about that which is not yet, but which can be realized by our conduct,
+namely, if it conforms to this idea.
+
+
+
+We can now end where we started at the beginning, namely, with the
+conception of a will unconditionally good. That will is absolutely
+good which cannot be evil- in other words, whose maxim, if made a
+universal law, could never contradict itself. This principle, then, is
+its supreme law: "Act always on such a maxim as thou canst at the same
+time will to be a universal law"; this is the sole condition under
+which a will can never contradict itself; and such an imperative is
+categorical. Since the validity of the will as a universal law for
+possible actions is analogous to the universal connexion of the
+existence of things by general laws, which is the formal notion of
+nature in general, the categorical imperative can also be expressed
+thus: Act on maxims which can at the same time have for their object
+themselves as universal laws of nature. Such then is the formula of an
+absolutely good will.
+
+Rational nature is distinguished from the rest of nature by this,
+that it sets before itself an end. This end would be the matter of
+every good will. But since in the idea of a will that is absolutely
+good without being limited by any condition (of attaining this or that
+end) we must abstract wholly from every end to be effected (since this
+would make every will only relatively good), it follows that in this
+case the end must be conceived, not as an end to be effected, but as
+an independently existing end. Consequently it is conceived only
+negatively, i.e., as that which we must never act against and which,
+therefore, must never be regarded merely as means, but must in every
+volition be esteemed as an end likewise. Now this end can be nothing
+but the subject of all possible ends, since this is also the subject
+of a possible absolutely good will; for such a will cannot without
+contradiction be postponed to any other object. The principle: "So act
+in regard to every rational being (thyself and others), that he may
+always have place in thy maxim as an end in himself," is accordingly
+essentially identical with this other: "Act upon a maxim which, at the
+same time, involves its own universal validity for every rational
+being." For that in using means for every end I should limit my
+maxim by the condition of its holding good as a law for every subject,
+this comes to the same thing as that the fundamental principle of
+all maxims of action must be that the subject of all ends, i.e., the
+rational being himself, be never employed merely as means, but as
+the supreme condition restricting the use of all means, that is in
+every case as an end likewise.
+
+It follows incontestably that, to whatever laws any rational being
+may be subject, he being an end in himself must be able to regard
+himself as also legislating universally in respect of these same laws,
+since it is just this fitness of his maxims for universal
+legislation that distinguishes him as an end in himself; also it
+follows that this implies his dignity (prerogative) above all mere
+physical beings, that he must always take his maxims from the point of
+view which regards himself and, likewise, every other rational being
+as law-giving beings (on which account they are called persons). In
+this way a world of rational beings (mundus intelligibilis) is
+possible as a kingdom of ends, and this by virtue of the legislation
+proper to all persons as members. Therefore every rational being
+must so act as if he were by his maxims in every case a legislating
+member in the universal kingdom of ends. The formal principle of these
+maxims is: "So act as if thy maxim were to serve likewise as the
+universal law (of all rational beings)." A kingdom of ends is thus
+only possible on the analogy of a kingdom of nature, the former
+however only by maxims, that is self-imposed rules, the latter only by
+the laws of efficient causes acting under necessitation from
+without. Nevertheless, although the system of nature is looked upon as
+a machine, yet so far as it has reference to rational beings as its
+ends, it is given on this account the name of a kingdom of nature. Now
+such a kingdom of ends would be actually realized by means of maxims
+conforming to the canon which the categorical imperative prescribes to
+all rational beings, if they were universally followed. But although a
+rational being, even if he punctually follows this maxim himself,
+cannot reckon upon all others being therefore true to the same, nor
+expect that the kingdom of nature and its orderly arrangements shall
+be in harmony with him as a fitting member, so as to form a kingdom of
+ends to which he himself contributes, that is to say, that it shall
+favour his expectation of happiness, still that law: "Act according to
+the maxims of a member of a merely possible kingdom of ends
+legislating in it universally," remains in its full force, inasmuch as
+it commands categorically. And it is just in this that the paradox
+lies; that the mere dignity of man as a rational creature, without any
+other end or advantage to be attained thereby, in other words, respect
+for a mere idea, should yet serve as an inflexible precept of the
+will, and that it is precisely in this independence of the maxim on
+all such springs of action that its sublimity consists; and it is this
+that makes every rational subject worthy to be a legislative member in
+the kingdom of ends: for otherwise he would have to be conceived
+only as subject to the physical law of his wants. And although we
+should suppose the kingdom of nature and the kingdom of ends to be
+united under one sovereign, so that the latter kingdom thereby
+ceased to be a mere idea and acquired true reality, then it would no
+doubt gain the accession of a strong spring, but by no means any
+increase of its intrinsic worth. For this sole absolute lawgiver must,
+notwithstanding this, be always conceived as estimating the worth of
+rational beings only by their disinterested behaviour, as prescribed
+to themselves from that idea [the dignity of man] alone. The essence
+of things is not altered by their external relations, and that
+which, abstracting from these, alone constitutes the absolute worth of
+man, is also that by which he must be judged, whoever the judge may
+be, and even by the Supreme Being. Morality, then, is the relation
+of actions to the relation of actions will, that is, to the autonomy
+of potential universal legislation by its maxims. An action that is
+consistent with the autonomy of the will is permitted; one that does
+not agree therewith is forbidden. A will whose maxims necessarily
+coincide with the laws of autonomy is a holy will, good absolutely.
+The dependence of a will not absolutely good on the principle of
+autonomy (moral necessitation) is obligation. This, then, cannot be
+applied to a holy being. The objective necessity of actions from
+obligation is called duty.
+
+From what has just been said, it is easy to see how it happens that,
+although the conception of duty implies subjection to the law, we
+yet ascribe a certain dignity and sublimity to the person who
+fulfils all his duties. There is not, indeed, any sublimity in him, so
+far as he is subject to the moral law; but inasmuch as in regard to
+that very law he is likewise a legislator, and on that account alone
+subject to it, he has sublimity. We have also shown above that neither
+fear nor inclination, but simply respect for the law, is the spring
+which can give actions a moral worth. Our own will, so far as we
+suppose it to act only under the condition that its maxims are
+potentially universal laws, this ideal will which is possible to us is
+the proper object of respect; and the dignity of humanity consists
+just in this capacity of being universally legislative, though with
+the condition that it is itself subject to this same legislation.
+
+
+
+The Autonomy of the Will as the Supreme Principle of Morality
+
+
+
+Autonomy of the will is that property of it by which it is a law
+to itself (independently of any property of the objects of
+volition). The principle of autonomy then is: "Always so to choose
+that the same volition shall comprehend the maxims of our choice as
+a universal law." We cannot prove that this practical rule is an
+imperative, i.e., that the will of every rational being is necessarily
+bound to it as a condition, by a mere analysis of the conceptions
+which occur in it, since it is a synthetical proposition; we must
+advance beyond the cognition of the objects to a critical
+examination of the subject, that is, of the pure practical reason, for
+this synthetic proposition which commands apodeictically must be
+capable of being cognized wholly a priori. This matter, however,
+does not belong to the present section. But that the principle of
+autonomy in question is the sole principle of morals can be readily
+shown by mere analysis of the conceptions of morality. For by this
+analysis we find that its principle must be a categorical imperative
+and that what this commands is neither more nor less than this very
+autonomy.
+
+
+
+Heteronomy of the Will as the Source of all spurious Principles
+
+ of Morality
+
+
+
+If the will seeks the law which is to determine it anywhere else
+than in the fitness of its maxims to be universal laws of its own
+dictation, consequently if it goes out of itself and seeks this law in
+the character of any of its objects, there always results
+heteronomy. The will in that case does not give itself the law, but it
+is given by the object through its relation to the will. This
+relation, whether it rests on inclination or on conceptions of reason,
+only admits of hypothetical imperatives: "I ought to do something
+because I wish for something else." On the contrary, the moral, and
+therefore categorical, imperative says: "I ought to do so and so, even
+though I should not wish for anything else." E.g., the former says: "I
+ought not to lie, if I would retain my reputation"; the latter says:
+"I ought not to lie, although it should not bring me the least
+discredit." The latter therefore must so far abstract from all objects
+that they shall have no influence on the will, in order that practical
+reason (will) may not be restricted to administering an interest not
+belonging to it, but may simply show its own commanding authority as
+the supreme legislation. Thus, e.g., I ought to endeavour to promote
+the happiness of others, not as if its realization involved any
+concern of mine (whether by immediate inclination or by any
+satisfaction indirectly gained through reason), but simply because a
+maxim which excludes it cannot be comprehended as a universal law in
+one and the same volition.
+
+
+
+ Classification of all Principles of Morality which can be
+
+ founded on the Conception of Heteronomy
+
+
+
+Here as elsewhere human reason in its pure use, so long as it was
+not critically examined, has first tried all possible wrong ways
+before it succeeded in finding the one true way.
+
+All principles which can be taken from this point of view are either
+empirical or rational. The former, drawn from the principle of
+happiness, are built on physical or moral feelings; the latter,
+drawn from the principle of perfection, are built either on the
+rational conception of perfection as a possible effect, or on that
+of an independent perfection (the will of God) as the determining
+cause of our will.
+
+Empirical principles are wholly incapable of serving as a foundation
+for moral laws. For the universality with which these should hold
+for all rational beings without distinction, the unconditional
+practical necessity which is thereby imposed on them, is lost when
+their foundation is taken from the particular constitution of human
+nature, or the accidental circumstances in which it is placed. The
+principle of private happiness, however, is the most objectionable,
+not merely because it is false, and experience contradicts the
+supposition that prosperity is always proportioned to good conduct,
+nor yet merely because it contributes nothing to the establishment
+of morality- since it is quite a different thing to make a
+prosperous man and a good man, or to make one prudent and
+sharp-sighted for his own interests and to make him virtuous- but
+because the springs it provides for morality are such as rather
+undermine it and destroy its sublimity, since they put the motives
+to virtue and to vice in the same class and only teach us to make a
+better calculation, the specific difference between virtue and vice
+being entirely extinguished. On the other hand, as to moral feeling,
+this supposed special sense, * the appeal to it is indeed superficial
+when those who cannot think believe that feeling will help them out,
+even in what concerns general laws: and besides, feelings, which
+naturally differ infinitely in degree, cannot furnish a uniform
+standard of good and evil, nor has anyone a right to form judgements
+for others by his own feelings: nevertheless this moral feeling is
+nearer to morality and its dignity in this respect, that it pays
+virtue the honour of ascribing to her immediately the satisfaction and
+esteem we have for her and does not, as it were, tell her to her
+face that we are not attached to her by her beauty but by profit.
+
+
+
+* I class the principle of moral feeling under that of happiness,
+because every empirical interest promises to contribute to our
+well-being by the agreeableness that a thing affords, whether it be
+immediately and without a view to profit, or whether profit be
+regarded. We must likewise, with Hutcheson, class the principle of
+sympathy with the happiness of others under his assumed moral sense.
+
+
+
+Amongst the rational principles of morality, the ontological
+conception of perfection, notwithstanding its defects, is better
+than the theological conception which derives morality from a Divine
+absolutely perfect will. The former is, no doubt, empty and indefinite
+and consequently useless for finding in the boundless field of
+possible reality the greatest amount suitable for us; moreover, in
+attempting to distinguish specifically the reality of which we are now
+speaking from every other, it inevitably tends to turn in a circle and
+cannot avoid tacitly presupposing the morality which it is to explain;
+it is nevertheless preferable to the theological view, first,
+because we have no intuition of the divine perfection and can only
+deduce it from our own conceptions, the most important of which is
+that of morality, and our explanation would thus be involved in a
+gross circle; and, in the next place, if we avoid this, the only
+notion of the Divine will remaining to us is a conception made up of
+the attributes of desire of glory and dominion, combined with the
+awful conceptions of might and vengeance, and any system of morals
+erected on this foundation would be directly opposed to morality.
+
+However, if I had to choose between the notion of the moral sense
+and that of perfection in general (two systems which at least do not
+weaken morality, although they are totally incapable of serving as its
+foundation), then I should decide for the latter, because it at
+least withdraws the decision of the question from the sensibility
+and brings it to the court of pure reason; and although even here it
+decides nothing, it at all events preserves the indefinite idea (of
+a will good in itself free from corruption, until it shall be more
+precisely defined.
+
+For the rest I think I may be excused here from a detailed
+refutation of all these doctrines; that would only be superfluous
+labour, since it is so easy, and is probably so well seen even by
+those whose office requires them to decide for one of these theories
+(because their hearers would not tolerate suspension of judgement).
+But what interests us more here is to know that the prime foundation
+of morality laid down by all these principles is nothing but
+heteronomy of the will, and for this reason they must necessarily miss
+their aim.
+
+In every case where an object of the will has to be supposed, in
+order that the rule may be prescribed which is to determine the
+will, there the rule is simply heteronomy; the imperative is
+conditional, namely, if or because one wishes for this object, one
+should act so and so: hence it can never command morally, that is,
+categorically. Whether the object determines the will by means of
+inclination, as in the principle of private happiness, or by means
+of reason directed to objects of our possible volition generally, as
+in the principle of perfection, in either case the will never
+determines itself immediately by the conception of the action, but
+only by the influence which the foreseen effect of the action has on
+the will; I ought to do something, on this account, because I wish for
+something else; and here there must be yet another law assumed in me
+as its subject, by which I necessarily will this other thing, and this
+law again requires an imperative to restrict this maxim. For the
+influence which the conception of an object within the reach of our
+faculties can exercise on the will of the subject, in consequence of
+its natural properties, depends on the nature of the subject, either
+the sensibility (inclination and taste), or the understanding and
+reason, the employment of which is by the peculiar constitution of
+their nature attended with satisfaction. It follows that the law would
+be, properly speaking, given by nature, and, as such, it must be known
+and proved by experience and would consequently be contingent and
+therefore incapable of being an apodeictic practical rule, such as the
+moral rule must be. Not only so, but it is inevitably only heteronomy;
+the will does not give itself the law, but is given by a foreign
+impulse by means of a particular natural constitution of the subject
+adapted to receive it. An absolutely good will, then, the principle of
+which must be a categorical imperative, will be indeterminate as
+regards all objects and will contain merely the form of volition
+generally, and that as autonomy, that is to say, the capability of the
+maxims of every good will to make themselves a universal law, is
+itself the only law which the will of every rational being imposes
+on itself, without needing to assume any spring or interest as a
+foundation.
+
+How such a synthetical practical a priori proposition is possible,
+and why it is necessary, is a problem whose solution does not lie
+within the bounds of the metaphysic of morals; and we have not here
+affirmed its truth, much less professed to have a proof of it in our
+power. We simply showed by the development of the universally received
+notion of morality that an autonomy of the will is inevitably
+connected with it, or rather is its foundation. Whoever then holds
+morality to be anything real, and not a chimerical idea without any
+truth, must likewise admit the principle of it that is here
+assigned. This section then, like the first, was merely analytical.
+Now to prove that morality is no creation of the brain, which it
+cannot be if the categorical imperative and with it the autonomy of
+the will is true, and as an a priori principle absolutely necessary,
+this supposes the possibility of a synthetic use of pure practical
+reason, which however we cannot venture on without first giving a
+critical examination of this faculty of reason. In the concluding
+section we shall give the principal outlines of this critical
+examination as far as is sufficient for our purpose.
+
+SEC_3
+
+ THIRD SECTION
+
+
+
+ TRANSITION FROM THE METAPHYSIC OF MORALS TO THE
+
+ CRITIQUE OF PURE PRACTICAL REASON
+
+
+
+The Concept of Freedom is the Key that explains the Autonomy of
+the Will
+
+
+
+The will is a kind of causality belonging to living beings in so far
+as they are rational, and freedom would be this property of such
+causality that it can be efficient, independently of foreign causes
+determining it; just as physical necessity is the property that the
+causality of all irrational beings has of being determined to activity
+by the influence of foreign causes.
+
+The preceding definition of freedom is negative and therefore
+unfruitful for the discovery of its essence, but it leads to a
+positive conception which is so much the more full and fruitful.
+
+Since the conception of causality involves that of laws, according
+to which, by something that we call cause, something else, namely
+the effect, must be produced; hence, although freedom is not a
+property of the will depending on physical laws, yet it is not for
+that reason lawless; on the contrary it must be a causality acting
+according to immutable laws, but of a peculiar kind; otherwise a
+free will would be an absurdity. Physical necessity is a heteronomy of
+the efficient causes, for every effect is possible only according to
+this law, that something else determines the efficient cause to
+exert its causality. What else then can freedom of the will be but
+autonomy, that is, the property of the will to be a law to itself? But
+the proposition: "The will is in every action a law to itself," only
+expresses the principle: "To act on no other maxim than that which can
+also have as an object itself as a universal law." Now this is
+precisely the formula of the categorical imperative and is the
+principle of morality, so that a free will and a will subject to moral
+laws are one and the same.
+
+On the hypothesis, then, of freedom of the will, morality together
+with its principle follows from it by mere analysis of the conception.
+However, the latter is a synthetic proposition; viz., an absolutely
+good will is that whose maxim can always include itself regarded as
+a universal law; for this property of its maxim can never be
+discovered by analysing the conception of an absolutely good will. Now
+such synthetic propositions are only possible in this way: that the
+two cognitions are connected together by their union with a third in
+which they are both to be found. The positive concept of freedom
+furnishes this third cognition, which cannot, as with physical causes,
+be the nature of the sensible world (in the concept of which we find
+conjoined the concept of something in relation as cause to something
+else as effect). We cannot now at once show what this third is to
+which freedom points us and of which we have an idea a priori, nor can
+we make intelligible how the concept of freedom is shown to be
+legitimate from principles of pure practical reason and with it the
+possibility of a categorical imperative; but some further
+preparation is required.
+
+
+
+ Freedom must be presupposed as a Property of the Will
+
+ of all Rational Beings
+
+
+
+It is not enough to predicate freedom of our own will, from Whatever
+reason, if we have not sufficient grounds for predicating the same
+of all rational beings. For as morality serves as a law for us only
+because we are rational beings, it must also hold for all rational
+beings; and as it must be deduced simply from the property of freedom,
+it must be shown that freedom also is a property of all rational
+beings. It is not enough, then, to prove it from certain supposed
+experiences of human nature (which indeed is quite impossible, and
+it can only be shown a priori), but we must show that it belongs to
+the activity of all rational beings endowed with a will. Now I say
+every being that cannot act except under the idea of freedom is just
+for that reason in a practical point of view really free, that is to
+say, all laws which are inseparably connected with freedom have the
+same force for him as if his will had been shown to be free in
+itself by a proof theoretically conclusive. * Now I affirm that we
+must attribute to every rational being which has a will that it has
+also the idea of freedom and acts entirely under this idea. For in
+such a being we conceive a reason that is practical, that is, has
+causality in reference to its objects. Now we cannot possibly conceive
+a reason consciously receiving a bias from any other quarter with
+respect to its judgements, for then the subject would ascribe the
+determination of its judgement not to its own reason, but to an
+impulse. It must regard itself as the author of its principles
+independent of foreign influences. Consequently as practical reason or
+as the will of a rational being it must regard itself as free, that is
+to say, the will of such a being cannot be a will of its own except
+under the idea of freedom. This idea must therefore in a practical
+point of view be ascribed to every rational being.
+
+
+
+* I adopt this method of assuming freedom merely as an idea which
+rational beings suppose in their actions, in order to avoid the
+necessity of proving it in its theoretical aspect also. The former
+is sufficient for my purpose; for even though the speculative proof
+should not be made out, yet a being that cannot act except with the
+idea of freedom is bound by the same laws that would oblige a being
+who was actually free. Thus we can escape here from the onus which
+presses on the theory.
+
+
+
+ Of the Interest attaching to the Ideas of Morality
+
+
+
+We have finally reduced the definite conception of morality to the
+idea of freedom. This latter, however, we could not prove to be
+actually a property of ourselves or of human nature; only we saw
+that it must be presupposed if we would conceive a being as rational
+and conscious of its causality in respect of its actions, i.e., as
+endowed with a will; and so we find that on just the same grounds we
+must ascribe to every being endowed with reason and will this
+attribute of determining itself to action under the idea of its
+freedom.
+
+Now it resulted also from the presupposition of these ideas that
+we became aware of a law that the subjective principles of action,
+i.e., maxims, must always be so assumed that they can also hold as
+objective, that is, universal principles, and so serve as universal
+laws of our own dictation. But why then should I subject myself to
+this principle and that simply as a rational being, thus also
+subjecting to it all other being endowed with reason? I will allow
+that no interest urges me to this, for that would not give a
+categorical imperative, but I must take an interest in it and
+discern how this comes to pass; for this properly an "I ought" is
+properly an "I would," valid for every rational being, provided only
+that reason determined his actions without any hindrance. But for
+beings that are in addition affected as we are by springs of a
+different kind, namely, sensibility, and in whose case that is not
+always done which reason alone would do, for these that necessity is
+expressed only as an "ought," and the subjective necessity is
+different from the objective.
+
+It seems then as if the moral law, that is, the principle of
+autonomy of the will, were properly speaking only presupposed in the
+idea of freedom, and as if we could not prove its reality and
+objective necessity independently. In that case we should still have
+gained something considerable by at least determining the true
+principle more exactly than had previously been done; but as regards
+its validity and the practical necessity of subjecting oneself to
+it, we should not have advanced a step. For if we were asked why the
+universal validity of our maxim as a law must be the condition
+restricting our actions, and on what we ground the worth which we
+assign to this manner of acting- a worth so great that there cannot be
+any higher interest; and if we were asked further how it happens
+that it is by this alone a man believes he feels his own personal
+worth, in comparison with which that of an agreeable or disagreeable
+condition is to be regarded as nothing, to these questions we could
+give no satisfactory answer.
+
+We find indeed sometimes that we can take an interest in a
+personal quality which does not involve any interest of external
+condition, provided this quality makes us capable of participating
+in the condition in case reason were to effect the allotment; that
+is to say, the mere being worthy of happiness can interest of itself
+even without the motive of participating in this happiness. This
+judgement, however, is in fact only the effect of the importance of
+the moral law which we before presupposed (when by the idea of freedom
+we detach ourselves from every empirical interest); but that we
+ought to detach ourselves from these interests, i.e., to consider
+ourselves as free in action and yet as subject to certain laws, so
+as to find a worth simply in our own person which can compensate us
+for the loss of everything that gives worth to our condition; this
+we are not yet able to discern in this way, nor do we see how it is
+possible so to act- in other words, whence the moral law derives its
+obligation.
+
+It must be freely admitted that there is a sort of circle here
+from which it seems impossible to escape. In the order of efficient
+causes we assume ourselves free, in order that in the order of ends we
+may conceive ourselves as subject to moral laws: and we afterwards
+conceive ourselves as subject to these laws, because we have
+attributed to ourselves freedom of will: for freedom and
+self-legislation of will are both autonomy and, therefore, are
+reciprocal conceptions, and for this very reason one must not be
+used to explain the other or give the reason of it, but at most only
+logical purposes to reduce apparently different notions of the same
+object to one single concept (as we reduce different fractions of
+the same value to the lowest terms).
+
+One resource remains to us, namely, to inquire whether we do not
+occupy different points of view when by means of freedom we think
+ourselves as causes efficient a priori, and when we form our
+conception of ourselves from our actions as effects which we see
+before our eyes.
+
+It is a remark which needs no subtle reflection to make, but which
+we may assume that even the commonest understanding can make, although
+it be after its fashion by an obscure discernment of judgement which
+it calls feeling, that all the "ideas" that come to us involuntarily
+(as those of the senses) do not enable us to know objects otherwise
+than as they affect us; so that what they may be in themselves remains
+unknown to us, and consequently that as regards "ideas" of this kind
+even with the closest attention and clearness that the understanding
+can apply to them, we can by them only attain to the knowledge of
+appearances, never to that of things in themselves. As soon as this
+distinction has once been made (perhaps merely in consequence of the
+difference observed between the ideas given us from without, and in
+which we are passive, and those that we produce simply from ourselves,
+and in which we show our own activity), then it follows of itself that
+we must admit and assume behind the appearance something else that
+is not an appearance, namely, the things in themselves; although we
+must admit that as they can never be known to us except as they affect
+us, we can come no nearer to them, nor can we ever know what they
+are in themselves. This must furnish a distinction, however crude,
+between a world of sense and the world of understanding, of which
+the former may be different according to the difference of the
+sensuous impressions in various observers, while the second which is
+its basis always remains the same, Even as to himself, a man cannot
+pretend to know what he is in himself from the knowledge he has by
+internal sensation. For as he does not as it were create himself,
+and does not come by the conception of himself a priori but
+empirically, it naturally follows that he can obtain his knowledge
+even of himself only by the inner sense and, consequently, only
+through the appearances of his nature and the way in which his
+consciousness is affected. At the same time beyond these
+characteristics of his own subject, made up of mere appearances, he
+must necessarily suppose something else as their basis, namely, his
+ego, whatever its characteristics in itself may be. Thus in respect to
+mere perception and receptivity of sensations he must reckon himself
+as belonging to the world of sense; but in respect of whatever there
+may be of pure activity in him (that which reaches consciousness
+immediately and not through affecting the senses), he must reckon
+himself as belonging to the intellectual world, of which, however,
+he has no further knowledge. To such a conclusion the reflecting man
+must come with respect to all the things which can be presented to
+him: it is probably to be met with even in persons of the commonest
+understanding, who, as is well known, are very much inclined to
+suppose behind the objects of the senses something else invisible
+and acting of itself. They spoil it, however, by presently
+sensualizing this invisible again; that is to say, wanting to make
+it an object of intuition, so that they do not become a whit the
+wiser.
+
+Now man really finds in himself a faculty by which he
+distinguishes himself from everything else, even from himself as
+affected by objects, and that is reason. This being pure spontaneity
+is even elevated above the understanding. For although the latter is a
+spontaneity and does not, like sense, merely contain intuitions that
+arise when we are affected by things (and are therefore passive),
+yet it cannot produce from its activity any other conceptions than
+those which merely serve to bring the intuitions of sense under
+rules and, thereby, to unite them in one consciousness, and without
+this use of the sensibility it could not think at all; whereas, on the
+contrary, reason shows so pure a spontaneity in the case of what I
+call ideas [ideal conceptions] that it thereby far transcends
+everything that the sensibility can give it, and exhibits its most
+important function in distinguishing the world of sense from that of
+understanding, and thereby prescribing the limits of the understanding
+itself.
+
+For this reason a rational being must regard himself qua
+intelligence (not from the side of his lower faculties) as belonging
+not to the world of sense, but to that of understanding; hence he
+has two points of view from which he can regard himself, and recognise
+laws of the exercise of his faculties, and consequently of all his
+actions: first, so far as he belongs to the world of sense, he finds
+himself subject to laws of nature (heteronomy); secondly, as belonging
+to the intelligible world, under laws which being independent of
+nature have their foundation not in experience but in reason alone.
+
+As a rational being, and consequently belonging to the
+intelligible world, man can never conceive the causality of his own
+will otherwise than on condition of the idea of freedom, for
+independence of the determinate causes of the sensible world (an
+independence which reason must always ascribe to itself) is freedom.
+Now the idea of freedom is inseparably connected with the conception
+of autonomy, and this again with the universal principle of morality
+which is ideally the foundation of all actions of rational beings,
+just as the law of nature is of all phenomena.
+
+Now the suspicion is removed which we raised above, that there was a
+latent circle involved in our reasoning from freedom to autonomy,
+and from this to the moral law, viz.: that we laid down the idea of
+freedom because of the moral law only that we might afterwards in turn
+infer the latter from freedom, and that consequently we could assign
+no reason at all for this law, but could only [present] it as a
+petitio principii which well disposed minds would gladly concede to
+us, but which we could never put forward as a provable proposition.
+For now we see that, when we conceive ourselves as free, we transfer
+ourselves into the world of understanding as members of it and
+recognise the autonomy of the will with its consequence, morality;
+whereas, if we conceive ourselves as under obligation, we consider
+ourselves as belonging to the world of sense and at the same time to
+the world of understanding.
+
+
+
+ How is a Categorical Imperative Possible?
+
+
+
+Every rational being reckons himself qua intelligence as belonging
+to the world of understanding, and it is simply as an efficient
+cause belonging to that world that he calls his causality a will. On
+the other side he is also conscious of himself as a part of the
+world of sense in which his actions, which are mere appearances
+[phenomena] of that causality, are displayed; we cannot, however,
+discern how they are possible from this causality which we do not
+know; but instead of that, these actions as belonging to the
+sensible world must be viewed as determined by other phenomena,
+namely, desires and inclinations. If therefore I were only a member of
+the world of understanding, then all my actions would perfectly
+conform to the principle of autonomy of the pure will; if I were
+only a part of the world of sense, they would necessarily be assumed
+to conform wholly to the natural law of desires and inclinations, in
+other words, to the heteronomy of nature. (The former would rest on
+morality as the supreme principle, the latter on happiness.) Since,
+however, the world of understanding contains the foundation of the
+world of sense, and consequently of its laws also, and accordingly
+gives the law to my will (which belongs wholly to the world of
+understanding) directly, and must be conceived as doing so, it follows
+that, although on the one side I must regard myself as a being
+belonging to the world of sense, yet on the other side I must
+recognize myself as subject as an intelligence to the law of the world
+of understanding, i.e., to reason, which contains this law in the idea
+of freedom, and therefore as subject to the autonomy of the will:
+consequently I must regard the laws of the world of understanding as
+imperatives for me and the actions which conform to them as duties.
+
+And thus what makes categorical imperatives possible is this, that
+the idea of freedom makes me a member of an intelligible world, in
+consequence of which, if I were nothing else, all my actions would
+always conform to the autonomy of the will; but as I at the same
+time intuite myself as a member of the world of sense, they ought so
+to conform, and this categorical "ought" implies a synthetic a
+priori proposition, inasmuch as besides my will as affected by
+sensible desires there is added further the idea of the same will
+but as belonging to the world of the understanding, pure and practical
+of itself, which contains the supreme condition according to reason of
+the former will; precisely as to the intuitions of sense there are
+added concepts of the understanding which of themselves signify
+nothing but regular form in general and in this way synthetic a priori
+propositions become possible, on which all knowledge of physical
+nature rests.
+
+The practical use of common human reason confirms this reasoning.
+There is no one, not even the most consummate villain, provided only
+that he is otherwise accustomed to the use of reason, who, when we set
+before him examples of honesty of purpose, of steadfastness in
+following good maxims, of sympathy and general benevolence (even
+combined with great sacrifices of advantages and comfort), does not
+wish that he might also possess these qualities. Only on account of
+his inclinations and impulses he cannot attain this in himself, but at
+the same time he wishes to be free from such inclinations which are
+burdensome to himself. He proves by this that he transfers himself
+in thought with a will free from the impulses of the sensibility
+into an order of things wholly different from that of his desires in
+the field of the sensibility; since he cannot expect to obtain by that
+wish any gratification of his desires, nor any position which would
+satisfy any of his actual or supposable inclinations (for this would
+destroy the pre-eminence of the very idea which wrests that wish
+from him): he can only expect a greater intrinsic worth of his own
+person. This better person, however, he imagines himself to be when be
+transfers himself to the point of view of a member of the world of the
+understanding, to which he is involuntarily forced by the idea of
+freedom, i.e., of independence on determining causes of the world of
+sense; and from this point of view he is conscious of a good will,
+which by his own confession constitutes the law for the bad will
+that he possesses as a member of the world of sense- a law whose
+authority he recognizes while transgressing it. What he morally
+"ought" is then what he necessarily "would," as a member of the
+world of the understanding, and is conceived by him as an "ought" only
+inasmuch as he likewise considers himself as a member of the world
+of sense.
+
+
+
+ Of the Extreme Limits of all Practical Philosophy.
+
+
+
+All men attribute to themselves freedom of will. Hence come all
+judgements upon actions as being such as ought to have been done,
+although they have not been done. However, this freedom is not a
+conception of experience, nor can it be so, since it still remains,
+even though experience shows the contrary of what on supposition of
+freedom are conceived as its necessary consequences. On the other side
+it is equally necessary that everything that takes place should be
+fixedly determined according to laws of nature. This necessity of
+nature is likewise not an empirical conception, just for this
+reason, that it involves the motion of necessity and consequently of a
+priori cognition. But this conception of a system of nature is
+confirmed by experience; and it must even be inevitably presupposed if
+experience itself is to be possible, that is, a connected knowledge of
+the objects of sense resting on general laws. Therefore freedom is
+only an idea of reason, and its objective reality in itself is
+doubtful; while nature is a concept of the understanding which proves,
+and must necessarily prove, its reality in examples of experience.
+
+There arises from this a dialectic of reason, since the freedom
+attributed to the will appears to contradict the necessity of
+nature, and placed between these two ways reason for speculative
+purposes finds the road of physical necessity much more beaten and
+more appropriate than that of freedom; yet for practical purposes
+the narrow footpath of freedom is the only one on which it is possible
+to make use of reason in our conduct; hence it is just as impossible
+for the subtlest philosophy as for the commonest reason of men to
+argue away freedom. Philosophy must then assume that no real
+contradiction will be found between freedom and physical necessity
+of the same human actions, for it cannot give up the conception of
+nature any more than that of freedom.
+
+Nevertheless, even though we should never be able to comprehend
+how freedom is possible, we must at least remove this apparent
+contradiction in a convincing manner. For if the thought of freedom
+contradicts either itself or nature, which is equally necessary, it
+must in competition with physical necessity be entirely given up.
+
+It would, however, be impossible to escape this contradiction if the
+thinking subject, which seems to itself free, conceived itself in
+the same sense or in the very same relation when it calls itself
+free as when in respect of the same action it assumes itself to be
+subject to the law of nature. Hence it is an indispensable problem
+of speculative philosophy to show that its illusion respecting the
+contradiction rests on this, that we think of man in a different sense
+and relation when we call him free and when we regard him as subject
+to the laws of nature as being part and parcel of nature. It must
+therefore show that not only can both these very well co-exist, but
+that both must be thought as necessarily united in the same subject,
+since otherwise no reason could be given why we should burden reason
+with an idea which, though it may possibly without contradiction be
+reconciled with another that is sufficiently established, yet
+entangles us in a perplexity which sorely embarrasses reason in its
+theoretic employment. This duty, however, belongs only to
+speculative philosophy. The philosopher then has no option whether
+he will remove the apparent contradiction or leave it untouched; for
+in the latter case the theory respecting this would be bonum vacans,
+into the possession of which the fatalist would have a right to
+enter and chase all morality out of its supposed domain as occupying
+it without title.
+
+We cannot however as yet say that we are touching the bounds of
+practical philosophy. For the settlement of that controversy does
+not belong to it; it only demands from speculative reason that it
+should put an end to the discord in which it entangles itself in
+theoretical questions, so that practical reason may have rest and
+security from external attacks which might make the ground debatable
+on which it desires to build.
+
+The claims to freedom of will made even by common reason are founded
+on the consciousness and the admitted supposition that reason is
+independent of merely subjectively determined causes which together
+constitute what belongs to sensation only and which consequently
+come under the general designation of sensibility. Man considering
+himself in this way as an intelligence places himself thereby in a
+different order of things and in a relation to determining grounds
+of a wholly different kind when on the one hand he thinks of himself
+as an intelligence endowed with a will, and consequently with
+causality, and when on the other he perceives himself as a
+phenomenon in the world of sense (as he really is also), and affirms
+that his causality is subject to external determination according to
+laws of nature. Now he soon becomes aware that both can hold good,
+nay, must hold good at the same time. For there is not the smallest
+contradiction in saying that a thing in appearance (belonging to the
+world of sense) is subject to certain laws, of which the very same
+as a thing or being in itself is independent, and that he must
+conceive and think of himself in this twofold way, rests as to the
+first on the consciousness of himself as an object affected through
+the senses, and as to the second on the consciousness of himself as an
+intelligence, i.e., as independent on sensible impressions in the
+employment of his reason (in other words as belonging to the world
+of understanding).
+
+Hence it comes to pass that man claims the possession of a will
+which takes no account of anything that comes under the head of
+desires and inclinations and, on the contrary, conceives actions as
+possible to him, nay, even as necessary which can only be done by
+disregarding all desires and sensible inclinations. The causality of
+such actions lies in him as an intelligence and in the laws of effects
+and actions [which depend] on the principles of an intelligible world,
+of which indeed he knows nothing more than that in it pure reason
+alone independent of sensibility gives the law; moreover since it is
+only in that world, as an intelligence, that he is his proper self
+(being as man only the appearance of himself), those laws apply to him
+directly and categorically, so that the incitements of inclinations
+and appetites (in other words the whole nature of the world of
+sense) cannot impair the laws of his volition as an intelligence. Nay,
+he does not even hold himself responsible for the former or ascribe
+them to his proper self, i.e., his will: he only ascribes to his
+will any indulgence which he might yield them if he allowed them to
+influence his maxims to the prejudice of the rational laws of the
+will.
+
+When practical reason thinks itself into a world of understanding,
+it does not thereby transcend its own limits, as it would if it
+tried to enter it by intuition or sensation. The former is only a
+negative thought in respect of the world of sense, which does not give
+any laws to reason in determining the will and is positive only in
+this single point that this freedom as a negative characteristic is at
+the same time conjoined with a (positive) faculty and even with a
+causality of reason, which we designate a will, namely a faculty of so
+acting that the principle of the actions shall conform to the
+essential character of a rational motive, i.e., the condition that the
+maxim have universal validity as a law. But were it to borrow an
+object of will, that is, a motive, from the world of understanding,
+then it would overstep its bounds and pretend to be acquainted with
+something of which it knows nothing. The conception of a world of
+the understanding is then only a point of view which reason finds
+itself compelled to take outside the appearances in order to
+conceive itself as practical, which would not be possible if the
+influences of the sensibility had a determining power on man, but
+which is necessary unless he is to be denied the consciousness of
+himself as an intelligence and, consequently, as a rational cause,
+energizing by reason, that is, operating freely. This thought
+certainly involves the idea of an order and a system of laws different
+from that of the mechanism of nature which belongs to the sensible
+world; and it makes the conception of an intelligible world
+necessary (that is to say, the whole system of rational beings as
+things in themselves). But it does not in the least authorize us to
+think of it further than as to its formal condition only, that is, the
+universality of the maxims of the will as laws, and consequently the
+autonomy of the latter, which alone is consistent with its freedom;
+whereas, on the contrary, all laws that refer to a definite object
+give heteronomy, which only belongs to laws of nature and can only
+apply to the sensible world.
+
+But reason would overstep all its bounds if it undertook to
+explain how pure reason can be practical, which would be exactly the
+same problem as to explain how freedom is possible.
+
+For we can explain nothing but that which we can reduce to laws, the
+object of which can be given in some possible experience. But
+freedom is a mere idea, the objective reality of which can in no
+wise be shown according to laws of nature, and consequently not in any
+possible experience; and for this reason it can never be
+comprehended or understood, because we cannot support it by any sort
+of example or analogy. It holds good only as a necessary hypothesis of
+reason in a being that believes itself conscious of a will, that is,
+of a faculty distinct from mere desire (namely, a faculty of
+determining itself to action as an intelligence, in other words, by
+laws of reason independently on natural instincts). Now where
+determination according to laws of nature ceases, there all
+explanation ceases also, and nothing remains but defence, i.e., the
+removal of the objections of those who pretend to have seen deeper
+into the nature of things, and thereupon boldly declare freedom
+impossible. We can only point out to them that the supposed
+contradiction that they have discovered in it arises only from this,
+that in order to be able to apply the law of nature to human
+actions, they must necessarily consider man as an appearance: then
+when we demand of them that they should also think of him qua
+intelligence as a thing in itself, they still persist in considering
+him in this respect also as an appearance. In this view it would no
+doubt be a contradiction to suppose the causality of the same
+subject (that is, his will) to be withdrawn from all the natural
+laws of the sensible world. But this contradiction disappears, if they
+would only bethink themselves and admit, as is reasonable, that behind
+the appearances there must also lie at their root (although hidden)
+the things in themselves, and that we cannot expect the laws of
+these to be the same as those that govern their appearances.
+
+The subjective impossibility of explaining the freedom of the will
+is identical with the impossibility of discovering and explaining an
+interest * which man can take in the moral law. Nevertheless he does
+actually take an interest in it, the basis of which in us we call
+the moral feeling, which some have falsely assigned as the standard of
+our moral judgement, whereas it must rather be viewed as the
+subjective effect that the law exercises on the will, the objective
+principle of which is furnished by reason alone.
+
+
+
+* Interest is that by which reason becomes practical, i.e., a cause
+determining the will. Hence we say of rational beings only that they
+take an interest in a thing; irrational beings only feel sensual
+appetites. Reason takes a direct interest in action then only when the
+universal validity of its maxims is alone sufficient to determine
+the will. Such an interest alone is pure. But if it can determine
+the will only by means of another object of desire or on the
+suggestion of a particular feeling of the subject, then reason takes
+only an indirect interest in the action, and, as reason by itself
+without experience cannot discover either objects of the will or a
+special feeling actuating it, this latter interest would only be
+empirical and not a pure rational interest. The logical interest of
+reason (namely, to extend its insight) is never direct, but
+presupposes purposes for which reason is employed.
+
+
+
+In order indeed that a rational being who is also affected through
+the senses should will what reason alone directs such beings that they
+ought to will, it is no doubt requisite that reason should have a
+power to infuse a feeling of pleasure or satisfaction in the
+fulfilment of duty, that is to say, that it should have a causality by
+which it determines the sensibility according to its own principles.
+But it is quite impossible to discern, i.e., to make it intelligible a
+priori, how a mere thought, which itself contains nothing sensible,
+can itself produce a sensation of pleasure or pain; for this is a
+particular kind of causality of which as of every other causality we
+can determine nothing whatever a priori; we must only consult
+experience about it. But as this cannot supply us with any relation of
+cause and effect except between two objects of experience, whereas
+in this case, although indeed the effect produced lies within
+experience, yet the cause is supposed to be pure reason acting through
+mere ideas which offer no object to experience, it follows that for us
+men it is quite impossible to explain how and why the universality
+of the maxim as a law, that is, morality, interests. This only is
+certain, that it is not because it interests us that it has validity
+for us (for that would be heteronomy and dependence of practical
+reason on sensibility, namely, on a feeling as its principle, in which
+case it could never give moral laws), but that it interests us because
+it is valid for us as men, inasmuch as it had its source in our will
+as intelligences, in other words, in our proper self, and what belongs
+to mere appearance is necessarily subordinated by reason to the nature
+of the thing in itself.
+
+The question then, "How a categorical imperative is possible," can
+be answered to this extent, that we can assign the only hypothesis
+on which it is possible, namely, the idea of freedom; and we can
+also discern the necessity of this hypothesis, and this is
+sufficient for the practical exercise of reason, that is, for the
+conviction of the validity of this imperative, and hence of the
+moral law; but how this hypothesis itself is possible can never be
+discerned by any human reason. On the hypothesis, however, that the
+will of an intelligence is free, its autonomy, as the essential formal
+condition of its determination, is a necessary consequence.
+Moreover, this freedom of will is not merely quite possible as a
+hypothesis (not involving any contradiction to the principle of
+physical necessity in the connexion of the phenomena of the sensible
+world) as speculative philosophy can show: but further, a rational
+being who is conscious of causality through reason, that is to say, of
+a will (distinct from desires), must of necessity make it practically,
+that is, in idea, the condition of all his voluntary actions. But to
+explain how pure reason can be of itself practical without the aid
+of any spring of action that could be derived from any other source,
+i.e., how the mere principle of the universal validity of all its
+maxims as laws (which would certainly be the form of a pure
+practical reason) can of itself supply a spring, without any matter
+(object) of the will in which one could antecedently take any
+interest; and how it can produce an interest which would be called
+purely moral; or in other words, how pure reason can be practical-
+to explain this is beyond the power of human reason, and all the
+labour and pains of seeking an explanation of it are lost.
+
+It is just the same as if I sought to find out how freedom itself is
+possible as the causality of a will. For then I quit the ground of
+philosophical explanation, and I have no other to go upon. I might
+indeed revel in the world of intelligences which still remains to
+me, but although I have an idea of it which is well founded, yet I
+have not the least knowledge of it, nor an I ever attain to such
+knowledge with all the efforts of my natural faculty of reason. It
+signifies only a something that remains over when I have eliminated
+everything belonging to the world of sense from the actuating
+principles of my will, serving merely to keep in bounds the
+principle of motives taken from the field of sensibility; fixing its
+limits and showing that it does not contain all in all within
+itself, but that there is more beyond it; but this something more I
+know no further. Of pure reason which frames this ideal, there remains
+after the abstraction of all matter, i.e., knowledge of objects,
+nothing but the form, namely, the practical law of the universality of
+the maxims, and in conformity with this conception of reason in
+reference to a pure world of understanding as a possible efficient
+cause, that is a cause determining the will. There must here be a
+total absence of springs; unless this idea of an intelligible world is
+itself the spring, or that in which reason primarily takes an
+interest; but to make this intelligible is precisely the problem
+that we cannot solve.
+
+Here now is the extreme limit of all moral inquiry, and it is of
+great importance to determine it even on this account, in order that
+reason may not on the one hand, to the prejudice of morals, seek about
+in the world of sense for the supreme motive and an interest
+comprehensible but empirical; and on the other hand, that it may not
+impotently flap its wings without being able to move in the (for it)
+empty space of transcendent concepts which we call the intelligible
+world, and so lose itself amidst chimeras. For the rest, the idea of a
+pure world of understanding as a system of all intelligences, and to
+which we ourselves as rational beings belong (although we are likewise
+on the other side members of the sensible world), this remains
+always a useful and legitimate idea for the purposes of rational
+belief, although all knowledge stops at its threshold, useful, namely,
+to produce in us a lively interest in the moral law by means of the
+noble ideal of a universal kingdom of ends in themselves (rational
+beings), to which we can belong as members then only when we carefully
+conduct ourselves according to the maxims of freedom as if they were
+laws of nature.
+
+
+
+ Concluding Remark
+
+
+
+The speculative employment of reason with respect to nature leads to
+the absolute necessity of some supreme cause of the world: the
+practical employment of reason with a view to freedom leads also to
+absolute necessity, but only of the laws of the actions of a
+rational being as such. Now it is an essential principle of reason,
+however employed, to push its knowledge to a consciousness of its
+necessity (without which it would not be rational knowledge). It is,
+however, an equally essential restriction of the same reason that it
+can neither discern the necessity of what is or what happens, nor of
+what ought to happen, unless a condition is supposed on which it is or
+happens or ought to happen. In this way, however, by the constant
+inquiry for the condition, the satisfaction of reason is only
+further and further postponed. Hence it unceasingly seeks the
+unconditionally necessary and finds itself forced to assume it,
+although without any means of making it comprehensible to itself,
+happy enough if only it can discover a conception which agrees with
+this assumption. It is therefore no fault in our deduction of the
+supreme principle of morality, but an objection that should be made to
+human reason in general, that it cannot enable us to conceive the
+absolute necessity of an unconditional practical law (such as the
+categorical imperative must be). It cannot be blamed for refusing to
+explain this necessity by a condition, that is to say, by means of
+some interest assumed as a basis, since the law would then cease to be
+a supreme law of reason. And thus while we do not comprehend the
+practical unconditional necessity of the moral imperative, we yet
+comprehend its incomprehensibility, and this is all that can be fairly
+demanded of a philosophy which strives to carry its principles up to
+the very limit of human reason.

+Project Gutenberg eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the US
+unless a copyright notice is included. Thus, we usually do not
+keep eBooks in compliance with any particular paper edition.
+
+We are now trying to release all our eBooks one year in advance
+of the official release dates, leaving time for better editing.
+Please be encouraged to tell us about any error or corrections,
+even years after the official publication date.
+
+Please note neither this listing nor its contents are final til
+midnight of the last day of the month of any such announcement.
+The official release date of all Project Gutenberg eBooks is at
+Midnight, Central Time, of the last day of the stated month. A
+preliminary version may often be posted for suggestion, comment
+and editing by those who wish to do so.
+
+Most people start at our Web sites at:
+https://gutenberg.org or
+http://promo.net/pg
+
+These Web sites include award-winning information about Project
+Gutenberg, including how to donate, how to help produce our new
+eBooks, and how to subscribe to our email newsletter (free!).
+
+
+Those of you who want to download any eBook before announcement
+can get to them as follows, and just download by date. This is
+also a good way to get them instantly upon announcement, as the
+indexes our cataloguers produce obviously take a while after an
+announcement goes out in the Project Gutenberg Newsletter.

+
+We produce about two million dollars for each hour we work. The
+time it takes us, a rather conservative estimate, is fifty hours
+to get any eBook selected, entered, proofread, edited, copyright
+searched and analyzed, the copyright letters written, etc. Our
+projected audience is one hundred million readers. If the value
+per text is nominally estimated at one dollar then we produce $2
+million dollars per hour in 2002 as we release over 100 new text
+files per month: 1240 more eBooks in 2001 for a total of 4000+
+We are already on our way to trying for 2000 more eBooks in 2002
+If they reach just 1-2% of the world's population then the total
+will reach over half a trillion eBooks given away by year's end.
+
+The Goal of Project Gutenberg is to Give Away 1 Trillion eBooks!
+This is ten thousand titles each to one hundred million readers,
+which is only about 4% of the present number of computer users.
