+
+<h2>THE METAPHYSICAL BASIS OF SCIENCE.</h2>
+
+<p>All knowledge is essentially one. The object-matter upon which intellect
+exerts itself, does not affect the subjective act of knowing. Physics,
+when stripped of that which is merely contingent, becomes metaphysics.
+Physical science deals with object-matter, and discusses the signs by
+which nature communicates her message&mdash;that is, phenomena. Metaphysical
+science has to do with the subject-mind, and discusses the meaning of
+the message. The one converts God's hieroglyphics into
+easily-intelligible language; the other translates this language into
+Idea. If this be true, there must be a unity of method in all science,
+however great the diversity of the object-matter investigated. This
+method is subjectively determined, that is, by the constitution of the
+mind, and not by the particular form of matter upon which intellectual
+energy may be exerted. If there is an essential unity in all knowledge,
+it is because there is a corresponding unity of method in all mental
+activity. It is only when we look upon what is to be known, that truth
+separates into sciences; but particular truths become particular
+sciences only under assumed relations to the whole of which they form a part.</p>
+
+<p>Objectively considered, science is classified knowledge; subjectively
+viewed, it is the laws or principles according to which knowledge is
+classified. Every actor implies an act&mdash;every<span class='pagenum'><a name="Page_2" id="Page_2">[Pg 2]</a></span> thinker a thought. We may
+therefore universally make this dual classification, according as we
+view the mental operation involved, or the attributes of objects which
+form the subject of thought. The possibility of science is conditioned
+upon the possibility of classification. Mere knowledge is not science,
+as the world ought to have learned by costly experience. Even classified
+knowledge may not be science; it becomes science not through previous
+classification, but in the act of being classified, and therefore only
+as the principle of classification is apprehended&mdash;that is, only as the
+particular application of the law of generalization is distinctly
+recognized. A man may know a book and know nothing more; he knows the
+science only when he is capable of making the book for himself. Mere
+knowledge thus differs from science in that the one is held only by the
+apprehensive powers of the mind, while the other passes beyond these
+into the reflective or ratiocinative. Pure science, then, must be wholly
+abstract. The forms and substances of Nature with which the scientific
+student deals, are only the discrete figures of the young mathematician,
+to be thrown aside with advancing knowledge. Matter is only the staff on
+which the mind leans, while too feeble to go alone. It is not the finely
+chiseled statue that renders a man a sculptor; it is the conception
+which is therein embodied. A day-laborer may have cut the stone, but
+only the artist could conceive the idea. So in science, we care but
+little for the particular results at which we arrive, compared with the
+laws, according to which the results have been attained.</p>
+
+<p>But conceptions cannot be communicated without being rendered objective.
+The ideal of the artist is locked up in his own mind, until on canvas,
+in marble, or by means of some other physical symbol, he communicates
+his high imaginings. Matter, then, according to the present constitution
+of things is the condition of intellectual communication. Law cannot be
+studied as abstract law; it can be studied only while acting, and that
+which exhibits this activity must be matter<span class='pagenum'><a name="Page_3" id="Page_3">[Pg 3]</a></span>&mdash;something which will
+always and uniformly obey. There can be no conception of force except as
+acting, and the sole medium of such activity is matter. Thus again,
+matter is the condition of all communication from nature to man. Science
+is thus, in a measure, determined by the conditions of its discovery and
+communication. But we must distinguish between an invariable condition
+and that which is thus conditioned. Matter is not science; it is only
+the condition of its discovery and communication. Air is not hearing; it
+is the condition of hearing. We do not study matter for the sake of the
+matter when we study science, but for the sake of the law communicated
+to us in these changes of matter, and Law is a metaphysical, not a
+physical idea. Reason, not sense, apprehends it. Law is, so to speak,
+formulated in the physical, but it is not material. Matter is only the
+vehicle of science, as language is the vehicle of thought.</p>
+
+<p>It is plain, then, that just as in mathematics we have a division into
+pure and mixed, according as we deal with matter in the abstract or in
+the concrete, so we may in any science make a corresponding division,
+according as we confine our attention to the laws revealed by matter or
+to the matter revealing the laws: in other words; just as we give
+attention to the ideas of the message, or to the language in which it is
+communicated. The language must first be learned, but the words used to
+communicate the message may be separately understood, and yet the
+meaning of the message wholly missed. Knowing only the one makes a
+charlatan; knowing the other makes a savan. The sciences based upon this
+objective study of Nature are denominated Natural Sciences; and because
+they lisp the first syllables of Nature's message to man, they should be
+his primary teachers. It is by their aid that the universal message of
+God to man must be read. They form, as it were, a public highway leading
+from Nature to God. But the difficulty is that observing men become so
+absorbed in admiring some splendid piece of Divine <span class='pagenum'><a name="Page_4" id="Page_4">[Pg 4]</a></span>engineering that
+they stop to gaze and wonder, until losing sight of everything above and
+beyond, they refuse to advance, fondly imagining that they have reached
+the end of the journey.</p>
+
+<p>The science based upon this subjective study of Nature is called
+metaphysics. Logic has been defined as "The Science of Thought;" it
+should be termed "The Science of Thinking." It is not a dead body which
+we are studying by dissection, but a living, vital Force, which we study
+by observing its activities. We find here the same error which we find
+elsewhere&mdash;a stopping with the material symbol, and an ignoring of the
+intellectual force which clothed itself with the symbol. Astronomy is
+not the science of circles and spheres, ellipses and ellipsoids, but of
+the Force whose sensible utterances are given in these curves. We might
+as well call Painting the science of pictures, or Sculpture the science
+of statues. So Language, the medium of thought, is only a symbol, less
+material indeed than pictures and statues, but still physical. What we
+want in "The Science of Thinking" is not the knowledge of symbols, but
+the knowledge of that which is symbolized. The chemist does not care for
+the compounds he finds in his retort; he seeks after the truth which
+these compounds formulate. Metaphysics and Physics evidently agree in
+this; that both are seeking to frame an articulate utterance of the Idea
+given in the diverse manifestations of Force&mdash;the Idea which includes
+all Potencies, the summing up of all phenomena into that final
+generalization which includes the intellectual as well as the material,
+until at last we reach the essential unity of all Truth.</p>
+
+<p>Science, then, is classification, or the discovery of the principles of
+classification, rather than an arbitrary acquaintance with things
+classified. Every science, however, must have an objective
+expression&mdash;that is, must be formulated. In this, both metaphysical and
+physical science agree; the only difference in this respect is, that in
+Physics, Nature gives us in the first place the material interpretation
+of the idea&mdash;that is,<span class='pagenum'><a name="Page_5" id="Page_5">[Pg 5]</a></span> the basis of classification&mdash;which we have only
+to translate into idea: while in metaphysics, we first have the idea to
+which we must furnish the objective utterance. We see here the precise
+difference between what is called the logical and the natural
+method&mdash;the one being usually called the reverse of the other. The
+difference is not so much a difference in intellectual procedure as in
+objective expression. For instance: The botanist has before him the
+whole range of vegetable forms. He notes resemblances and differences,
+and groups plants into species and genera, but his work is not ended
+when these are named and known, and their qualities discovered. He is
+seeking amidst these multifarious forms for the law of vegetable growth
+and reproduction. Every organ of the plant is the symbol of an idea, and
+these ideas form the science of Botany. These Ideas are
+metaphysical&mdash;that is intellectual, and only their sensible
+manifestation is physical. The symbols of these Ideas, being given in
+Nature, must be learned from observation before they can be used
+intelligently, just as words must be learned before one can speak a
+language. Mastery of the means of expression is as essential to the
+communication of ideas an is the possession of the ideas themselves. The
+botanist observes an individual plant, and notes its characteristics. He
+observes others which possess some of these characteristics whilst
+others are wanting. He forms a class-type from these agreeing
+attributes, and gives this new collocation of characteristics a name.
+Nature never presents this class-type absolutely; it is found nowhere
+but in intellect. What has the botanist done but to retranslate the
+communication of Nature into Idea, and then to express this idea by less
+complicated and less physical symbols? Man's province in this case is
+simply to interpret the hieroglyphics of Nature into a more readily
+comprehended language&mdash;to express that simply which nature has expressed
+confusedly. The scientist restricts himself to the interpretation of a
+single class of symbols, as the Botanist to plants, the Zoologist to
+animals, but the<span class='pagenum'><a name="Page_6" id="Page_6">[Pg 6]</a></span> end sought in each case is the same&mdash;that is, to
+change all these physical utterances of Nature into Idea, and to secure
+for this Idea a method of expression involving the least possible
+materiality of symbol&mdash;that is, to change individual facts and phenomena
+into general principles, which, because abstract, are unchangeable. When
+this has been done, the work of the Naturalist ceases, but the work of
+Man, the Thinker is not done; it is only just begun. By assuming the
+ultimate expressions of the various natural sciences as individual and
+not as typical, we can treat the truths reached by them precisely as the
+Botanist treated plants, and, rejecting points of of difference, may
+find in them all some central idea. This is the province of the
+metaphysician. He seeks the law of Idea, he determines the law of
+Thinking, just as all other laws are determined, from a study of the
+symbols formulating its expression in Nature. When this law has been
+distinctly enunciated, and freed from all intermixture with the
+contingent, then the work of the metaphysician ceases, the <i>summum
+genus</i> has been reached. The truths communicated in the symbols of
+Nature, have been correlated and enunciated, and finally translated from
+the dialect of man the physical into the language of man the
+intellectual. Physical science determines the separate words of this
+message of God, the letters of which are scattered throughout Nature.
+Metaphysics combines these words into propositions which enunciate a
+distinct truth. There is therefore neither conflict nor variation
+between the method of Logic and the method of Nature. The movement of
+both is in the same direction; the only difference is in the point of
+starting. And another truth no less important, which follows from the
+foregoing discussion, is that the method of Nature is fundamental to the
+method of Logic. Physics should precede metaphysics, but not exclude it;
+both are essential to every true science, and physics, which stops with
+physics, leads man by dazzling promises into some Utopian desert only to
+leave him there to die of hunger. And it is no less true that
+<span class='pagenum'><a name="Page_7" id="Page_7">[Pg 7]</a></span>metaphysics, without this basis in experimental science, is illusory
+and untrustworthy, wherever the original data are necessarily empirical.</p>
+
+<p>Two conditions are thus necessary to all science: a body of knowable
+truth capable of being systematized; and an intelligence capable of
+apprehending and systematizing it. One of these conditions is physical
+and one is metaphysical; and all true science must be the resultant of
+Law and Idea, the Objective and the Subjective, the twin forces of
+Nature and Man. If either of these conditions be wanting, there can be
+no true science, for science can neither be "evolved from the depths of
+the personal consciousness," nor can the scattered letters of scientific
+truth, as given in nature, arrange themselves into the words of a
+significant message. Knowledge must be classified before it is science,
+and that which classifies can only be intellect&mdash;discovering and
+enunciating this classification according to the laws of mental action.
+As prominence is given to one or other of these two conditions we have
+the division into Logical and Natural, but the fundamental principle of
+classification is the same in both&mdash;it being simply the law of
+intellectual action&mdash;just as the law which governs the action of the
+levers of a loom will determine the pattern of the woven fabric. There
+can, therefore, be no conflict between the methods of Logic and those of
+Nature. The determining element in all classification, whether of the
+phenomena of Mind or of the grosser phenomena of Matter is uniformly and
+always the same&mdash;the law of intellectual action.</p>
+
+<p>Science then resolves itself into a determination of this Law of mental
+activity, so that in an ultimate analysis, all science is metaphysical,
+just as all science primarily is physical. Here, as elsewhere, Law can
+be studied only in its objective manifestations. The Law of Thinking can
+be educed only from expressed Thought, but the Law is not objective
+thought, any more than the idea of the sculptor is marble, or the
+conception<span class='pagenum'><a name="Page_8" id="Page_8">[Pg 8]</a></span> of the painter is paint. The simplest expression of thought
+is not the syllogism but the logical proposition. Now, it is plain that
+if the proposition is the formulation&mdash;the material representative of
+thought&mdash;if we study it as we study other natural symbols, we will find
+in it the fundamental Law of Thinking, and ultimately the fundamental
+Law of all Science: just as, if it were possible to reduce all
+elementary substances to one, the chemist would be able to find in that
+one a condensed expression of chemical science.</p>
+
+<p>What then is a proposition? Simply stated, it is the assertion of
+relation between two terms; or more abstractly, it is the reference of
+an individual to its species&mdash;the assertion of a classification. We find
+here the same duality which we noticed above. If we give prominence to
+the individual notion, we consider the proposition in extension; if we
+turn our attention to the specific notion we consider the proposition in
+intention: in the one case referring to the individuals composing the
+class, in the other to the attributes composing the class-type. The
+first corresponds to induction, the second to deduction. When we study
+individuals we study physics; when we study the attributes composing the
+class-type, we study metaphysics. The Law of Thinking as educed from a
+study of the proposition is the law of classification. The proposition,
+considered affirmatively, asserts explicitly agreement between certain
+attributes of two terms; that is, it asserts a classification. The aim
+of science is to reach this proposition, to discover and assert the
+principle of classification&mdash;in other words, to formulate metaphysically
+what nature has presented physically. We must find, then, the first or
+fundamental law of thinking in this <i>integration</i> or classification.
+This fundamental law may be subdivided into two species, according to
+the two terms of the proposition; of which the first may be stated thus:
+"Every possible object of thought is to a certain extent identical with
+every other"; and as the proposition implicitly states disagreement, the
+second may be stated thus:<span class='pagenum'><a name="Page_9" id="Page_9">[Pg 9]</a></span> "Every possible object of thought is to a
+certain extent diverse from every other." The first gives the positive
+(subjective) condition of the proposition, the second the negative
+(objective) condition: both together constitute the conditions of
+thinking. The proposition is thus the assertion of the same in the
+different. The proposition also asserts, implicitly, the <i>tertium quid</i>,
+or the basis of classification&mdash;the class-type, to which both terms are
+referred&mdash;that is, the proposition secondarily asserts an analysis.
+According to the first condition we have the inductive process;
+according to the second we have the deductive process. A complete
+movement of idea from its purely physical symbolization to its
+metaphysical interpretation, must involve both these processes.</p>
+
+<p>The mind possesses the power of analysis; it can watch its own
+operations and retrace its steps, until it arrives at the original data
+of consciousness; but analysis cannot comprise the whole of the logical
+process. Before there can be analysis there must be something to be
+analyzed; before steps can be retraced, they must be taken. We must not
+confound a condition with a Law&mdash;the one is a conception antecedent to
+all action, a genus to which the particular activity may be referred;
+the other is coincident with action. The one is the medium of the other.
+We may illustrate this idea by science itself, which is reached only by
+an analysis of Art. Matter is the condition of the expression of an
+idea; hence to all but the artist, Art must precede Science, but this
+cannot be in the case of the artist; in his mind the Idea is first
+conceived, and there it is given expression in the forms of Art. Here,
+as uniformly in Nature, the whole absolutely precedes the part&mdash;the
+universal exists before the particular&mdash;God before man. Truth absolute
+thus exists before truth conditioned. Science before Art. Remove
+conditions and the conditioned becomes the absolute; art and science
+coincide. But truth which is assumed to be out of all relations, cannot
+be comprehended by man, and practically is not. Even the universal
+propositions<span class='pagenum'><a name="Page_10" id="Page_10">[Pg 10]</a></span> of deduction express universality under conditions&mdash;that
+is universality of relation; just as infinity in mathematics means that
+which passes measurement, while in fact between infinity and measurement
+there is no relation, and the infinite is thus incomprehensible as an
+object of thought, although by no means unrecognizable as a necessary
+condition antecedent to all intellectual action. It is of vital
+importance that we note this distinction, because reasoning, i. e.
+classification, is possible only so long as we deal with what is
+admitted to be under relation: if we assume a term to be out of all
+relation, it ceases to be an object of thought&mdash;it can neither be
+classified nor unclassified; it is beyond reason. Mathematics can
+proceed with its investigations only so long as it treats all quantities
+as measurable; it must wholly cease its calculations if an infinite term
+be introduced. To claim that analysis represents the complete normal
+action of the intellect in reasoning, is ultimately to claim that the
+initial point of thinking is the <i>summum genus</i> of thought&mdash;God. Now God
+is undoubtedly the initial point of absolute thought, but he is not the
+beginning of human thought. Intellectually speaking, God is the final
+generalization; every movement possible to him must be one of
+analysis&mdash;a differentiation of Himself, so to speak, by negatives. Thus
+the course of absolute Thought, beginning with God, must be first
+towards a complete differentiation into ultimate individualization; and
+lastly a complete integration again of individuals into an infinite
+whole. This dual action completes the circle of intellectual activity.
+We have dropped attribute after attribute until we have reached the last
+possible analysis; but we do not stop here, but by the assumption of
+attributes we again reach the highest possible synthesis. This must be
+the method of the divine activity, successive differentiation and
+integration, the closing in of a mighty circle of infinity, embracing
+all the finite, but never losing the essential characteristic of the infinite.</p>
+
+<p>Now, if this also represent the exact movement of the finite<span class='pagenum'><a name="Page_11" id="Page_11">[Pg 11]</a></span> mind in
+action&mdash;that is, in reasoning, man must be God. Man is finite. Even his
+infinite is only the immeasurable&mdash;not that which is without the
+category of measure. He cannot begin where the Infinite begins, at the
+highest possible generalization,&mdash;but he must begin with the finite. If
+what we have shown above be true, man must begin with the individual,
+and the first mental act of the positive character of thinking, is the
+reference of this individual notion to a class. Now the <i>class-notion</i>
+is the same as the individual notion, less certain attributes as
+<i>individual</i> attributes, but gathered into a larger whole. This process
+is plainly integration; we are rejecting from the new conception
+whatever prevents enlarging the class. Each higher generalization
+involves all the attributes of the lower, not individually, but
+specifically or generically. In the final generalization, extension and
+intension coalesce. Just as we reach the individual by differentiating a
+universal through successive negations, we reach the universal again, by
+integration, by successively denying the negations through which we just
+now differentiated. The movement of the finite mind in reasoning is thus
+from the individual through the universal to the individual again.</p>
+
+<p>Science thus parts into two great branches&mdash;one seeking to establish
+principles by what we have called integration, and the other the
+elucidation of facts by <i>a priori</i> reasoning instead of observation.
+That is, the aim of true science is to free man from the restrictions of
+the finite, and to place him in possession of the infinite&mdash;the closing
+in of a lesser circle of infinite truth, yet never losing hold upon the
+finite. In accordance with this view we see science pursuing its
+integrations until it has identified as composing an essential unity all
+the various manifestations of force. This is the finite becoming the
+infinite, for unity is, in so far, infinity&mdash;God is one, a unity, not a
+unit. But we also see science going beyond this point, and by a new
+series of differentiations reaching truths new to experience, if indeed
+not impossible to experience.</p>
+
+<p><span class='pagenum'><a name="Page_12" id="Page_12">[Pg 12]</a></span></p><p>Between these two limits all knowledge is forever moving. It can never
+rest. The tide of thought sweeps onward towards the infinite&mdash;God
+following it to its final absorption into the <i>I Am</i>, simple
+being,&mdash;while finite man, because of his finiteness, can only reach
+those universals which are infinite only to human thought. Like men on a
+journey we leave the train when we have reached our journey's end, but
+the train passes on out of sight in the distance, sending back, now and
+then, tokens of its progress, as it thunders over a bridge, or whistles
+shrill as it nears some further stopping place, until at last all is
+still, not because the train has stopped, but because we can follow it
+no further with our senses. Even after science has reached the utmost
+limit possible to it, it is not satisfied to rest there, but starts at
+once upon its return trip, to bring to notice undiscovered facts hidden
+in these mighty generalizations. Thus the pendulum of intellectual
+activity unceasingly vibrates between the infinite and the finite, never
+resting, because Idea and Matter, the force of Man and the force of
+Nature can never be completely identified.</p>

+<h2>THE PHILOSOPHY OF EVOLUTION.</h2>
+
+<p>The intellectual processes of a rational being must proceed according to
+some law. They cannot succeed each other at hap-hazard. The notion of
+rationality is conditioned upon this regular procedure; if this be
+wanting, the essential character of rational action is wanting. But to
+say that rational processes are determined by law, and conditioned upon
+a regular procedure, is simply to assert that the steps in ratiocination
+are so related to each other that the relation of each to every other
+may be determined by the application of the law&mdash;the difference between
+any two steps being analogous to the difference between any other two.
+The astronomer determines the orbit of a planet from three observations,
+because he thereby determines the law of variation between these points;
+from which he assumes that this law will be constant, presenting a
+series of terms each differentiated according the series of differences
+already determined.</p>
+
+<p>Applying the same principle to mental phenomena, we may determine the
+law of intellectual action. Thoughts are discriminated by the presence
+or absence of certain attributes. At one extreme we find the <i>summum
+genus</i>, comprising the fewest possible attributes distinguishing an
+idea; at the other extreme we find the individual, comprising any number
+of attributes. Between these two extremes we find a regular series of
+intermediate terms. The movement of an idea from the general to the
+individual is like the motion of a planet through one-half of its orbit;
+while the return movement from the individual to the general,
+corresponds to the motion of the planet over the remaining half of its
+orbit. The same law governs both movements and unites the two halves of
+the orbit into a<span class='pagenum'><a name="Page_14" id="Page_14">[Pg 14]</a></span> single whole; and a series of observations taken at
+equal distances, will, by the uniformity of differences presented,
+reveal the operation of the same law in this dual manifestation. Upon
+examining the processes of deduction and induction, we find in each the
+same series of terms, differing only in the fact that they are in
+inverse order, and this correspondence reveals the operation of one and
+the same law. An inductive series is only a deductive series read
+backward. Any two terms in a series whether inductive or deductive,
+differ only in the degree of generality, and differ similarly from a
+third term, so that two being known the third can be therefrom
+determined. In a deductive series the terms differ by a constant
+increase in the number of individualizing attributes&mdash;a concept being
+expanded into a deductive series by such regular additions. Having two
+terms we can proceed to the third&mdash;that is, from two propositions
+expressing this relation, we can proceed to a conclusion. In an
+inductive series the terms differ by a constant diminution in the number
+of individualizing attributes&mdash;an individual term being expanded into an
+inductive series, by successively dropping the attributes which compose
+the individual term, until we reach the required degree of generalization.</p>
+
+<p>Thought must proceed in one of these two directions. The object-matter
+of thought being composed wholly of attributes can differ only in the
+presence or absence of certain attributes. A combination, then, of these
+two movements must complete the intellectual orbit. The direction of the
+movement of the mind will be determined by the end proposed. When we
+possess the knowledge of phenomena and wish to discover law&mdash;that is,
+when we seek information&mdash;we proceed by induction, from the individual
+to the general. When possessed of knowledge, we wish to discover its
+applications, when knowing the law, we wish to determine the phenomena
+necessarily resulting therefrom, we proceed by deduction&mdash;from the
+general to the individual. Complete knowledge, then, consists in the
+highest<span class='pagenum'><a name="Page_15" id="Page_15">[Pg 15]</a></span> possible generalization, and the expansion of this term into a
+series, ending only with the last possible individualization. The aim of
+physical science is to determine that half of the intellectual orbit
+which lies between the individual and the general&mdash;the aim of
+metaphysical science is to trace the other half which lies between the
+general and the individual. When we seek to know what is, we proceed by
+induction&mdash;the method of the phenomenal. When, knowing what is, we
+proceed to determine what hence must be, we proceed by deduction&mdash;the
+method of the Necessary. Thus Science, at first seeking principles,
+proceeds by induction to establish them; but after these fundamental
+principles have been established, it proceeds deductively to determine
+what must result from them, without waiting to discover these truths by observation.</p>
+
+<p>Knowledge is thus complete just in proportion to the extension of its
+scope through generalization. The higher the generalization, the more
+inclusive will it be, and the <i>summum genus</i>, or the final
+generalization, will be the highest attainable reach of knowledge. When
+man can make no further generalization, his knowledge will be, in so
+far, absolute and complete, and all that remains possible to him will be
+the practical application of what he already knows. Perfect knowledge is
+nothing but perfect generalization. The Supreme Intelligence being
+hypothetically possessed of all knowledge, that is, having discriminated
+the absolute <i>summum genus</i>, can proceed no further in this direction;
+his intellectual activity must be exerted in a descending series, or
+from the general towards the individual, and this process must be, as we
+have seen above, by a determinate series of steps, fixed by the
+operation of a definite law, which law proceeds by the successive
+addition of attributes to the general.</p>
+
+<p>Complete knowledge, being complete generalization, the lines of all
+science will necessarily converge, as they approach this generalization,
+until all sciences coalesce in one science, and all truth is reduced to
+a single expression in the utterance<span class='pagenum'><a name="Page_16" id="Page_16">[Pg 16]</a></span> of the final conception. In
+accordance with the laws of thinking, this general term is reached by
+successive omissions of particularizing attributes, until at last we
+reach Being&mdash;the absolute <i>summum genus</i>, wholly free from individual
+attributes, and thereby embracing everything possible to thought,
+whether material or immaterial. But this <i>summum genus</i> must be
+predicable of this whole. Matter and mind may thus be reduced to a
+single category, and the physical and the intellectual finally coalesce
+in this last generalization. Materialism and idealism thus differ merely
+in the degree of generalization reached&mdash;or rather they both agree in
+avoiding the final generalization which identifies both matter and mind.
+Materialism must always deal with the individual, for matter can appear
+under no other form. Idealism must always rest upon the general, for
+thought, to be thought, must state a generalization. Each, however,
+finds its explanation in the other, and both are harmonized by the
+application of the law of intellectual action above given. Matter and
+Mind are complementary, not incompatible. They differ with each other,
+but they agree in being similarly related to a third term. Matter is
+objective; it is thought taking form, becoming individual, manifesting
+itself in space. Mind is subjective. The one appeals to the senses; the
+other is known only to the consciousness.</p>
+
+<p>Science reaches its full development only when it includes both physical
+and intellectual phenomena within its scope. Every step which it takes
+carries it further from the purely physical, and brings it nearer the
+purely intellectual&mdash;that is the development of physical science is from
+the individual towards the general, and it reaches its end, its
+completion, only when the last distinction, that of subjective and
+objective, has disappeared in the last possible generalization. When the
+objective has been identified with the subjective, the distinction
+between Mind and Matter has been obliterated, and we have reached the
+Supreme Intelligence&mdash;the "I Am" of Scripture&mdash;simple Being.</p>
+
+<p><span class='pagenum'><a name="Page_17" id="Page_17">[Pg 17]</a></span></p><p>Matter is the formal expression of thought, or the necessary condition
+of such expression, and in this condition is found the link that
+connects the subjective and objective manifestations of <i>being</i>.
+Subjectivity is ideality, as objectivity is materiality. The
+consciousness can take cognizance only of what is within itself, and
+therefore without every other. Consciousness is therefore wholly
+personal. To communicate an idea it must be placed within the
+consciousness of another. To reach this result it must cease to be
+personal, must pass out of the subjective consciousness into objective
+form, so as to be placed in the same relation to the speaker and the
+hearer. Thought, out of the consciousness of the thinker, is objective
+to him, and to render thought objective is to give it material form.
+Thought to be communicated, must pass out of the consciousness of the
+thinker into a material representation. The assumption of material form
+individualizes the idea. The artist's mind may be filled with splendid
+conceptions, but no one but he can look within his consciousness and see
+them. Before others can have any knowledge of his thoughts, he must give
+them form, or embody them in statues or paintings. The soul of the
+musician may be thrilled by the harmonies that his imagination creates,
+but no other soul can join him in this ecstasy until he has given form
+to his conceptions. So the thinker must embody his thoughts in language
+before he can communicate them to another. Matter, then, is the vehicle
+by which thought is communicated, and, so far as we are concerned, the
+necessary condition of such communication, so that the conception of
+thought apart from the thinker involves the intervention of material
+forms, and it is by the interpretation of these symbolical forms that we
+discover the idea.</p>
+
+<p>Now, let us suppose a Supreme Intelligence. The intellectual processes
+of such a Being, to be conceived as rational by us, must be identical
+with ours, or at least analogous to ours. The possession of infinite
+attributes may in fact free him from the control of any law, but it is
+impossible for us to conceive<span class='pagenum'><a name="Page_18" id="Page_18">[Pg 18]</a></span> an intelligence acting otherwise than in
+accordance with law. So that if the Supreme Intelligence is to
+communicate with man, it must be in obedience to the laws which control
+our mental activities. The Divine thought must, then, like human
+conceptions, be communicated by means of physical symbols.</p>
+
+<p>The Supreme Intelligence, being the final generalization, must possess
+all knowledge, and the only intelligent action possible to him from our
+point of view, is from this absolute generalization towards the concrete
+and individual. The absolute general is purely subjective, which, to
+become cognizable, must be rendered objective. This can be secured to us
+only through the intervention of material forms. From this point of
+view, matter is only the symbol of thought&mdash;thought apart from the
+thinker. The first result of the divine activity in self-manifestation
+would be the analysis of <i>being</i> into subjective and objective&mdash;that is
+the discrimination of mind and matter, which terms are severally the
+final generalizations of the two fundamental divisions of science.
+Matter, then, mere formless, chaotic matter, would be the first result
+of creative activity. Following the development of this idea in its
+continually increasing individuality, as new attributes are severally
+added, matter assumes determinate form and becomes related in systems,
+as the various so-called elementary substances are discriminated, until
+finally all truth, capable of being revealed by inorganic matter, is
+presented to us.</p>
+
+<p>Add the idea of organism and we have the two great divisions of
+phenomena&mdash;material and vital. The higher the generalization, the fewer
+will be the attributes composing the concept, and thus the simpler will
+be the form symbolizing its expression. As in the case of matter, the
+first result of the divine activity was more matter, undiscriminated by
+any further attribute; so here, we have, as the first organic creation,
+a concrete expression of the highest possible generalization comprising
+the fewest possible attributes&mdash;that is, forms of<span class='pagenum'><a name="Page_19" id="Page_19">[Pg 19]</a></span> life involving the
+fewest individual characteristics. To matter add the simplest organic
+attribute&mdash;that is, the one lying nearest the genus&mdash;and we have mere
+organized matter, the simple cell, the foundation of all life, no matter
+how great its future complexity, equally the origin of animal and
+vegetable growth, which are as yet entirely undiscriminated. This would
+be the first appearance of life.<a name="FNanchor_1_1" id="FNanchor_1_1"></a><a href="#Footnote_1_1" class="fnanchor">[1]</a> Differentiating again by the
+addition of a new attribute, and organic being is subdivided into the
+two species, vegetable and animal. Beginning with these typical forms,
+adding single attributes in a continuous series, we at last reach the
+highest types of animals and plants. Finally, add rationality to the
+animal, and we reach man, the highest and therefore the most complex
+type of life, and who, so far as we are concerned, must be the end of
+creation. We cannot conceive of any higher creation, because we cannot
+add an attribute to those we already possess, any more than we can
+conceive of an additional sense by which to cognize such new attribute.</p>
+
+<p>This process has been determined from the very outset by those
+intellectual laws which we cannot disobey, and which we cannot conceive
+disobeyed by an intelligent creator. If the law of intellectual action
+require this process from the simple to the complex, the concrete
+representation of the steps of this process must indicate the operation
+of this law, and must also proceed from the simple and rudimentary to
+the complex and highly developed. An intelligent Creator in revealing
+his thought must follow the method which our minds must follow in
+interpreting this revelation. When we know and seek to communicate our
+knowledge, we proceed from the general to the specific.<a name="FNanchor_2_2" id="FNanchor_2_2"></a><a href="#Footnote_2_2" class="fnanchor">[2]</a> The Creator
+assumed to be infinite in knowledge would therefore follow this process
+instead of the method peculiar to investigation. The law of intellectual
+action <span class='pagenum'><a name="Page_20" id="Page_20">[Pg 20]</a></span>determines this method, and the conditions of intellectual
+communication determine the representation of this method in the
+material expression of the ideas communicated. Considering the operation
+of this law under these conditions, we find that the thought
+communicating only, as nearly as may be, the generic idea, will be
+distinguished from it by the addition of but a single attribute as the
+generic by itself is incapable of being represented in concrete form,
+the expression of this thought in form will present us matter
+distinguished from matter in general by but a single attribute. The
+least possible individualizing attribute added to the highest possible
+generalization gives us the simplest expression of an idea, and the form
+or the organism symbolizing this thought will be the simplest form and
+the simplest organism possible. For instance: in organic life the
+highest generalization barely individualized will give us the simple
+cell; and no matter what degree of complexity we subsequently reach by
+the addition of an almost infinite number of attributes, we nevertheless
+begin in every case with the same starting point.</p>
+
+<p>Each higher type is reached by adding to a lower. The higher thus
+embraces all that can be found in the lower, and something besides. This
+method is invariable, and can never be departed from. The genus must
+always be predicable of every individual component of every species
+contained under it. Translating this law into the forms of material
+expression, and it requires each higher species to physically include
+all lower species, and to differ from them only by addition. Man, the
+highest type, must thus include all the attributes of the cell as
+physically expressed, and without them he would not be man. The
+differences between no two terms in a series can be total. If the
+successive steps in a train of thought must be related, so that no two
+notions will be wholly distinct from each other, these notions will
+constitute a series, each term of which will, in a measure, determine
+the next, so soon as the law of the series is discovered; and if this
+train of<span class='pagenum'><a name="Page_21" id="Page_21">[Pg 21]</a></span> thought be objectively presented, it will afford a
+corresponding series of physical terms, each one of which will in like
+manner determine the next. But thought is impossible unless by a train
+of ideas so related. Its physical expression will therefore be equally
+impossible except by a series of physical terms similarly related, each
+one of which in some manner determines the next. There must then be a
+perfect continuity in the line that reaches from the simplest form of
+matter through all grades of organic life up to man, the highest
+expression of the divine idea. There can be no break in the chain of
+thought, because the law of the logical process forbids it: there can be
+no break in the series of material symbols for the conditions of
+concrete expression equally forbid it. A symbol is nothing except as it
+represents that which is to be symbolized. So the symbols form a
+physical series, because the thoughts symbolized form a logical series.</p>
+
+<p>If the creator has fully revealed his thought, it must be by a series of
+physical terms arranged in such a manner as to indicate the logical
+series of ideas symbolized. Every form of matter is a symbol of thought,
+and challenges interpretation. Every change in form corresponds to an
+antecedent change in idea, and must be intended to reveal it. As
+thought, then, begins its evolution with the general and proceeds to the
+individual by a series of terms each of which is similarly related to
+both extremes, we must find the material enunciation of this process
+assuming the form of a series of terms, beginning with mere nebulous
+matter, grading into organic life, and organic life presenting us with a
+similar series beginning with the mere cell and ending with man. So
+rigid and invariable must this serial arrangement be that if a term in
+either series be wanting, we are authorized to hypothetically interpolate it.</p>
+
+<p>"Nature never makes a leap," says the scientific investigator, as he
+studies the material symbols of thought. "Thought never makes a leap,"
+says the metaphysician, as he studies the necessary laws of rational
+action: and both have uttered the<span class='pagenum'><a name="Page_22" id="Page_22">[Pg 22]</a></span> same truth. We prove a proposition by
+determining the steps by which it was educed from a more generic
+statement. Science must proceed in the same manner, for science only
+discovers the track of mind&mdash;it does not make the track, it only follows
+it. If then we find the chain of evolution broken at any point, science
+must either stop there, or assume the wanting term in the series. We
+have the right to interpolate these missing terms, for we must assume
+that the thoughts of God communicated to us in material forms constitute
+a continuous revelation, beginning with Himself, the final
+generalization, and ending with man the highest individualization. These
+limits are fixed&mdash;the one by the nature of God, and the other by the
+nature of man. Between these two extremes we must find a series of
+intermediate terms. Any other conception of their relation than that of
+a determinate series is impossible and irrational; and a series, so far
+as it means anything, means evolution of some sort. Finding the relation
+between these terms&mdash;distinguishing the <i>same</i> which reproduces itself,
+and the <i>different</i> which introduces a new term&mdash;that is, determining
+the law of apparent evolution&mdash;is the problem presented to science.</p>
+
+<p>The astronomer found Bode's law to all appearance violated by the
+omission of a planet between Mars and Jupiter. He could see no reason
+for the law, but if the planets had been placed by an intelligent
+Creator, some order of arrangement must be discoverable according to
+which their position was determined. The Creator being intelligent, it
+is impossible to conceive them placed fortuitously. There must then be a
+link between Mars and Jupiter, because the law once established cannot
+be broken. The same law may be observed in the arrangement of leaves
+around the axis of a plant. If intelligence arranged them they must be
+arranged in some order, for intelligence never performs the least act
+without a purpose. Each leaf or pair of leaves is not a mere duplication
+of the previous leaf or pair of leaves. The relation which subsists<span class='pagenum'><a name="Page_23" id="Page_23">[Pg 23]</a></span>
+between any two sets in the series expresses the idea of the Creator,
+and this must be constant. Completing the series as indicated by
+different plants, we may assume that if any term is apparently wanting,
+it is only because it has not been discovered. In neither of these cases
+would it be asserted that any physical evolution had taken place&mdash;the
+terms form a series of which each term is equally determined by the
+operation of a fixed law; and yet it is an operation precisely analogous
+to that which in the case of animals presents every appearance of a real
+evolution. Take, for instance, a series of animals, presenting at one
+period of time the simplest and most rudimentary forms, and at another
+the most complex and highly organized; we cannot do otherwise than
+conceive these two extremes as related by intermediate terms, through
+the operation of some law which holds good throughout the series. The
+relation subsisting between any two, must be the same as that subsisting
+between any other two similarly situated, or a departure from that
+relation which is itself governed by a definite law discoverable from a
+comparison of two sets of terms. The application of this law is so
+universal and so rigid that we need not hesitate to interpolate a
+missing term, and confidently assert that it either does exist or has
+existed. To deny this principle is to deny the necessity of continuity
+in reasoning. This continuity of thought is represented in matter by the
+persistence of generic forms under specific differences. But just as the
+specific is the generic with certain additions, so the individual is
+this same generic with still further additions; and these additions,
+whether considered solely in space, as given in the symbols of physical
+science, or in time as in the conceptions of intellectual science, must
+be determined by the same unvarying law. The persistence of the same
+form furnishes us the means of identifying this relation, while the
+differences reveal to us the successive steps by which the generic was
+differentiated into the individual.</p>
+
+<p>If the creative thought has been expressed by the forms of<span class='pagenum'><a name="Page_24" id="Page_24">[Pg 24]</a></span> matter, the
+laws of thought must be thus expressed in the relative forms of matter.
+Anything less than this, while it might interpret isolated ideas, would
+not communicate the method of the creative process, and science is
+nothing but the discovery of this method. If the terms of the logical
+process must be arranged in a series, the physical symbols rendering
+this logical process cognizable, must be arranged in a similar series,
+for science becomes impossible when the logical process becomes undiscoverable.</p>
+
+<p>The differences between the terms in this series must be cognizable. Two
+terms which are indistinguishable are practically identical; and two
+terms which are not identical vary by a difference which is cognizable
+by itself apart from either term. The steps in the logical evolution of
+the final term. <i>Being</i> must be separable to be cognizable, and the
+material forms interpreting these steps to the senses must also be
+distinguishable. A species differs from the genus by the addition of at
+least one attribute. Now, if the species is distinguishable from the
+genus, the attribute which differentiates it, must be separately
+cognizable&mdash;so also the individual differs from the species by the
+addition of attributes, which must in like manner be separately
+cognizable, or the species will never be conceived independently of the
+individuals. A thought cannot proceed by insensible steps, nor can its
+material expression vary otherwise than by determinate and
+distinguishable differences. The distinction of species is thus a
+logical necessity. The addition of distinct attributes to the genus
+gives origin to distinct species; variation in attributes not affecting
+their substantial identity gives rise to varieties. One species, then,
+cannot become another, except by the assumption of a new specific
+attribute, so that one species passes into another precisely as the
+genus passes into the species, and that is just as, and not otherwise,
+than one thought passes into another.</p>
+
+<p>The fundamental law of the logical process is that we pass from the
+generic towards the individual; from the simple to<span class='pagenum'><a name="Page_25" id="Page_25">[Pg 25]</a></span> the complex.
+Induction can proceed only by assuming a genus at the outset&mdash;that is,
+by assuming certain attributes in the individual to be generic.
+Translate this law into material forms, and we have each higher&mdash;that is
+more complex&mdash;species evolved from the lower by the addition of some new
+characteristic. This new attribute cannot be added by the functional
+activity of the lower organism; that can only reproduce itself. A
+thought does not change merely through repeated expression. We pass to
+the conclusion of a syllogism, not from each term, but from a comparison
+of the premises&mdash;and this requires an intellectual operation entirely
+distinct from a mere apprehension of the terms. It is one thing to
+comprehend the premises; it is quite another to deduce a conclusion from
+them. It may necessarily follow, but it requires a separate act of the
+mind to reach it. Premises will not of themselves reach a conclusion.</p>
+
+<p>Reading this same truth in the forms of matter, we may say that species
+will not pass into higher species without the intervention of a force
+distinct from either. The impulse which adds a new attribute must be
+intellectually separable from all those pre-existing, and its material
+representation must be physically distinct from pre-existing forms. This
+complete separability precludes the possibility of mere physical
+genesis. The added attribute is presented by a new form of matter,
+revealing the presence of a new thought&mdash;a new effect, requiring the
+agency of a new cause. In accordance with the usual economy of nature,
+who never duplicates her forces, change will be made only so far as may
+be necessary to communicate the additional idea. Organisms representing
+previous thoughts will be added to, in order to express the expansion of
+the thought, instead of a creation <i>de novo</i> in each instance. Thus an
+identical cellular structure will be found in all organic beings, from
+the lowest to the highest, each higher type carrying forward the idea
+and its physical expression found in the lower. The differences between
+no two terms in the series can<span class='pagenum'><a name="Page_26" id="Page_26">[Pg 26]</a></span> be total, nor can any two terms be
+identical, as each higher species will embrace all the attributes of the
+lower, differing only by the addition of others. This is simply the
+physical expression of the logical truth that whatever can be predicated
+of the genus can be predicated of every individual contained under it.
+As the individual is only the expansion of the genus, so higher physical
+types must also be similar expansions of lower.</p>
+
+<p>Here, then, is evolution, or development: primarily an evolution of the
+generic into the individual, the continued differentiation of a generic
+idea through successive individualizations, each adding to the previous
+group of attributes, thus rendering the idea increasingly complex; and,
+secondly, an apparent physical evolution or development, interpreting
+this logical process by a series of physical forms so related as to
+reveal the relation existing between the thoughts thus interpreted. In
+the physical representation of the ideas so related, there must be an
+apparent physical evolution&mdash;that is, the process of evolution logically
+must, like the ideas thus evolved, have a physical expression, and the
+successive steps in this logical evolution must be revealed by material
+forms bearing an analogous relation, and thereby expressing the logical
+process. Matter is nothing, so far as we are now concerned, but the
+condition necessary to the objective expression of thought. Every phase
+of matter is simply an objective formulation of a corresponding phase of
+thought. Every addition to form implies an antecedent increase of
+thought, as there can be no formal expression until there is something
+to be expressed. There can, then, be no such thing as mere material
+evolution, for whatever is material is only symbolical.</p>
+
+<p>Matter being thus wholly inert, the origin of the impulse towards
+greater complexity must be sought for outside of that which undergoes
+the change. The movement by which one species becomes a higher is not an
+elaboration, an extension or a differentiation of existing attributes,
+but involves the <span class='pagenum'><a name="Page_27" id="Page_27">[Pg 27]</a></span>positive addition of a new attribute, different and
+distinct from any or all previously existing. One species cannot pass
+into another by an innate impulse, for a species is an entity composed
+of a determinate number of attributes, and all attributes potentially
+present must be considered as actually present. We cannot say that the
+child is a different species from the man, and that one passes into the
+other by a process of evolution, because all the essential attributes of
+the man are potentially present in the child. If the polyp, by the
+action of innate forces, operating through a series of ages, however
+extended, can, without any impulse from without, develop itself into a
+man, then the polyp is as much a man as a boy is, differing only in the
+time required for development: and the data for the final deduction of
+the highest types of creation must be furnished in the most elementary
+forms of life.</p>
+
+<p>The force manifesting itself in organic life is readily distinguishable
+from the organism by which it is manifested. Life and organization are
+not synonyms; one is the condition of the other, but a condition is not
+a cause. We can consider force apart from organism, and this possible
+separation in thought proves that the same form may not represent both,
+but that life can absolutely exist apart from organs which serve to give
+it a physical manifestation.<a name="FNanchor_3_3" id="FNanchor_3_3"></a><a href="#Footnote_3_3" class="fnanchor">[3]</a> Physical life being conditioned upon
+organization, whenever the organism varies, the vital force thus
+manifested must also vary, such variation being necessarily antecedent
+to its manifestation. The organism varies, because it must, in order to
+express the added thought. Change in organism, therefore, is not induced
+by simple organic action, because the organs and the force acting
+through them can be distinguished. Assuming that matter is the objective
+or formal representation of thought, there can be no change in the
+material expression without a corresponding change in the antecedent
+conception. There can, then, be physical evolution, only as there is
+antecedent logical <span class='pagenum'><a name="Page_28" id="Page_28">[Pg 28]</a></span>evolution, and then only because of this logical
+evolution and not because of the operation of an innate organic force.
+Force, whatever may be its genesis, is only the exertion of power, not
+the increase of it. Exertion limits the view to the force immediately in
+operation. We may replace one manifestation by another, but the quantity
+is neither increased nor diminished by this change. Change in form
+implies the operation of force: and apart from such manifestation in
+matter, it escapes the tests of science, and passes into the purely
+metaphysical notion of cause. And unless the operation of force be
+constant, or, if different forces are blended, variable according to
+some determinate law, the action of which is constant and discoverable,
+so that the different units of force are separately measurable, the
+force thus irregular in its action can never be placed in any scientific
+category. Evolution, then, cannot proceed from any innate organic
+impulse, unless the force that tends to exact reproduction, and the
+force that induces a change be equally and separately cognizable. Change
+must proceed according to some law which accounts for the change, and
+distinguishes between the normal exertion of power and that exertion
+which causes a deviation. Science, to be science, must explain apparent
+exceptions as fully as the regular operation of forces, and that which
+causes the irregularity must be as distinctly cognizably by itself as
+the force which acts regularly. Anything less than this is not science.
+The discovery of Neptune was the result of the application of this
+principle; it was a successful attempt to discriminate the force which
+caused variation from the force which operated regularly.</p>
+
+<p>Each species represents the operation of certain vital forces, and one
+cannot physically pass into another except by the increase of this
+force, or at least by a change in the manner of its manifestation; and
+this increase in amount or this change in direction must separately be
+accounted for. Nor does it matter, for the purposes of this discussion,
+as to the genesis of this added increment, further than to show that its
+origin must<span class='pagenum'><a name="Page_29" id="Page_29">[Pg 29]</a></span> be exterior to the organism by which its presence is
+manifested; for vital energy acting through an organism is a unit, and
+cannot, even in thought, be separated into distinguishable portions.
+Change in the direction of vital energy indicates that the original
+impulse has been modified in its action by encountering another force,
+for nothing but force can change the direction of force. It does not
+fall within the range of this paper to determine the nature of this
+exterior force which is thus distinguishable from that acting through
+the vital organization, and therefore capable of separate objective
+representation. Metaphysically we may say that force is resolvable into
+will, but will being purely personal is incapable of material
+representation, and thus cannot enter into the determinations of
+physical science, which does not seek to discover the origin of force,
+but deals solely with its presence.</p>
+
+<p>As the logician must assume his premises, and, as a logician, cannot
+question their truth, so the physicist must assume a force in operation,
+and, as a physicist, cannot examine its genesis. The physical or the
+metaphysical method of inquiry is valid only so long as restricted to
+physical or metaphysical processes: a mixture of the two methods will
+give results satisfactory neither to science nor to philosophy. As logic
+furnishes no criterion by which to test the absolute truth of
+propositions, but deals wholly with conclusions drawn from given
+premises, so science furnishes no data by which to determine the
+absolute genesis of force, but restricts its enquiries to the phenomena
+resulting from a force given. For the student of physical science cause
+and effect is only the transference of a given and determined force from
+one material form to another. If this idea is to be traced further, it
+must be studied outside the limits of physics. This study belongs to metaphysics.</p>
+
+<p>Now, if physical science does not deal with the origin of the initial
+force, but assumes at the outset its presence, no more does it fall
+within its province to examine into the origin of the increments which
+give to physical forms that variety which<span class='pagenum'><a name="Page_30" id="Page_30">[Pg 30]</a></span> renders science possible.
+Science deals with results, not antecedents; and after having determined
+results, it is not authorized to affirm that one species has produced
+another by evolution, or has produced it at all. If there are agreements
+between different organisms by which they are brought into relation,
+there are also differences by which they are discriminated, and these
+differences imply increments of force; and to assert that one organism
+has evolved another is to determine not merely the presence of this new
+increment, but also to determine its origin. Scientific investigation
+deals with phenomena which give evidence to the senses of a
+<i>transference</i> of force from one form or from one manifestation to
+another. Transference is not increase&mdash;an effect can be no more than the
+evolution of what was potentially present in the cause; it cannot add to
+it. The origin of the force must be investigated according to intellectual laws.</p>
+
+<p class="tbrk">&nbsp;</p>
+
+<p>It has been argued that a Supreme Intelligence in manifesting his
+thought will, according to the necessary laws of rational activity, pass
+from the universal and general to the particular and individual, or from
+concepts involving few attributes to those involving these and others;
+and that these steps in the rational process must be represented in a
+corresponding physical series; and that the communication of thought is
+conditioned upon this physical representation. If the logical series
+comprises one thousand terms, each related to the preceding according to
+logical law the physical series must comprise one thousand terms, each
+physically related in such a manner as to reveal this law. As the
+highest generalization comprises the fewest attributes, the concrete
+expression of this idea will present the simplest possible physical form
+and the least complexity of organization, and thus will present the
+lowest types of life; and as the individual comprises the greatest
+number of attributes, its concrete expression will present the greatest
+complexity, and consequently the highest type of life.<span class='pagenum'><a name="Page_31" id="Page_31">[Pg 31]</a></span> We have seen
+that the logical process begins with the general and ends with the
+individual; its material expression must therefore begin with the lowest
+orders and end with the highest. But the individual cannot be
+immediately derived from the general without the intervention of
+intermediate generalizations. No more in the concrete expression of this
+deduction can we pass from the lowest types to the highest without the
+intervention of an intermediate series. These intermediate terms are not
+capable of independent interpretation; they find their full explanation
+only in the extremes of the series&mdash;God and Man.</p>
+
+<p>If, then, in the intellectual process from the abstract and universal
+towards the concrete and individual, we find a constant evolution of
+idea, each advance being an addition to the previous conception, each
+new term in the series embracing all the attributes of the preceding,
+and differing only by addition; and if thought is possible only on this
+condition; it necessarily follows that the material representation of
+this thought must present physical forms similarly related, so that,
+leaving out of view the intellectual genesis of this relation, the
+observer might conclude that these forms compose a series evolved from a
+primordial cell in accordance with an organic law. But such we find to
+be the universal law of intellectual procedure: this apparent
+development or evolution must, therefore, be the condition of the
+communication of such intellectual process, and the physical terms are
+brought into this relation by the fact that they symbolize the logical
+process. If the material symbols of thought were unrelated physically,
+the thoughts thus expressed would also be unrelated and independent. But
+such a supposition readers Science impossible, for its one aim is to
+find the <i>same</i> in the <i>different</i>. If there be no <i>same</i>, there can be
+no science: if there be no <i>different</i>, there can be no science. Thought
+proceeds by adding the <i>different</i> to the <i>same</i> in an endless series,
+and this addition of the <i>different</i> to the <i>same</i> expressed in concrete
+forms is<span class='pagenum'><a name="Page_32" id="Page_32">[Pg 32]</a></span> what is called evolution. If no evolution were apparent in
+Nature, there could be no Science; for those steps which to the
+naturalist indicate evolution, being only the physical expression&mdash;the
+formulation&mdash;of the logical process, afford the means by which the
+student reaches the highest generalization. If these steps be wanting,
+he cannot proceed.</p>
+
+<p>Admitting then to its fullest extent the fact that, judged from a purely
+physical point of view, all organic forms seem to have been derived each
+from its immediate predecessor, by a mere functional impulse; and
+admitting that science is possible upon no other condition; we claim
+that these material forms are brought into such relation by intellectual
+evolution, and not by physical genesis; they represent an evolution of
+Thought and not an evolution of Matter. We know from consciousness that
+this process of evolution is the method of our thinking. We know also
+that the divine thought can be rendered intelligible to us upon no other
+hypothesis than that which supposes it to be governed by the laws which
+control human thought. Translating the physical symbols which we see
+about us, and which present this appearance of evolution, we infer that
+this is the method according to which the divine mind proceeded. Science
+will not materially err in its physical results, if it adopt the
+hypothesis of physical evolution, but it must confine its attention to
+physics; it is only as we attempt higher generalizations that the
+insufficiency of the hypothesis becomes manifest in its failure to
+satisfy the conditions of the problem as presented to philosophy.</p>

+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive
+Foundation
+
+The Project Gutenberg Literary Archive Foundation is a non profit
+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.
+
+The Foundation's principal office is located at 4557 Melan Dr. S.
+Fairbanks, AK, 99712., but its volunteers and employees are scattered
+throughout numerous locations. Its business office is located at
+809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email
+business@pglaf.org. Email contact links and up to date contact
+information can be found at the Foundation's web site and official
+page at http://pglaf.org

+
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.

+
+
+
+
+THE METAPHYSICAL BASIS OF SCIENCE.
+
+
+All knowledge is essentially one. The object-matter upon which intellect
+exerts itself, does not affect the subjective act of knowing. Physics,
+when stripped of that which is merely contingent, becomes metaphysics.
+Physical science deals with object-matter, and discusses the signs by
+which nature communicates her message--that is, phenomena. Metaphysical
+science has to do with the subject-mind, and discusses the meaning of
+the message. The one converts God's hieroglyphics into
+easily-intelligible language; the other translates this language into
+Idea. If this be true, there must be a unity of method in all science,
+however great the diversity of the object-matter investigated. This
+method is subjectively determined, that is, by the constitution of the
+mind, and not by the particular form of matter upon which intellectual
+energy may be exerted. If there is an essential unity in all knowledge,
+it is because there is a corresponding unity of method in all mental
+activity. It is only when we look upon what is to be known, that truth
+separates into sciences; but particular truths become particular
+sciences only under assumed relations to the whole of which they form a
+part.
+
+Objectively considered, science is classified knowledge; subjectively
+viewed, it is the laws or principles according to which knowledge is
+classified. Every actor implies an act--every thinker a thought. We may
+therefore universally make this dual classification, according as we
+view the mental operation involved, or the attributes of objects which
+form the subject of thought. The possibility of science is conditioned
+upon the possibility of classification. Mere knowledge is not science,
+as the world ought to have learned by costly experience. Even classified
+knowledge may not be science; it becomes science not through previous
+classification, but in the act of being classified, and therefore only
+as the principle of classification is apprehended--that is, only as the
+particular application of the law of generalization is distinctly
+recognized. A man may know a book and know nothing more; he knows the
+science only when he is capable of making the book for himself. Mere
+knowledge thus differs from science in that the one is held only by the
+apprehensive powers of the mind, while the other passes beyond these
+into the reflective or ratiocinative. Pure science, then, must be wholly
+abstract. The forms and substances of Nature with which the scientific
+student deals, are only the discrete figures of the young mathematician,
+to be thrown aside with advancing knowledge. Matter is only the staff on
+which the mind leans, while too feeble to go alone. It is not the finely
+chiseled statue that renders a man a sculptor; it is the conception
+which is therein embodied. A day-laborer may have cut the stone, but
+only the artist could conceive the idea. So in science, we care but
+little for the particular results at which we arrive, compared with the
+laws, according to which the results have been attained.
+
+But conceptions cannot be communicated without being rendered objective.
+The ideal of the artist is locked up in his own mind, until on canvas,
+in marble, or by means of some other physical symbol, he communicates
+his high imaginings. Matter, then, according to the present constitution
+of things is the condition of intellectual communication. Law cannot be
+studied as abstract law; it can be studied only while acting, and that
+which exhibits this activity must be matter--something which will
+always and uniformly obey. There can be no conception of force except as
+acting, and the sole medium of such activity is matter. Thus again,
+matter is the condition of all communication from nature to man. Science
+is thus, in a measure, determined by the conditions of its discovery and
+communication. But we must distinguish between an invariable condition
+and that which is thus conditioned. Matter is not science; it is only
+the condition of its discovery and communication. Air is not hearing; it
+is the condition of hearing. We do not study matter for the sake of the
+matter when we study science, but for the sake of the law communicated
+to us in these changes of matter, and Law is a metaphysical, not a
+physical idea. Reason, not sense, apprehends it. Law is, so to speak,
+formulated in the physical, but it is not material. Matter is only the
+vehicle of science, as language is the vehicle of thought.
+
+It is plain, then, that just as in mathematics we have a division into
+pure and mixed, according as we deal with matter in the abstract or in
+the concrete, so we may in any science make a corresponding division,
+according as we confine our attention to the laws revealed by matter or
+to the matter revealing the laws: in other words; just as we give
+attention to the ideas of the message, or to the language in which it is
+communicated. The language must first be learned, but the words used to
+communicate the message may be separately understood, and yet the
+meaning of the message wholly missed. Knowing only the one makes a
+charlatan; knowing the other makes a savan. The sciences based upon this
+objective study of Nature are denominated Natural Sciences; and because
+they lisp the first syllables of Nature's message to man, they should be
+his primary teachers. It is by their aid that the universal message of
+God to man must be read. They form, as it were, a public highway leading
+from Nature to God. But the difficulty is that observing men become so
+absorbed in admiring some splendid piece of Divine engineering that
+they stop to gaze and wonder, until losing sight of everything above and
+beyond, they refuse to advance, fondly imagining that they have reached
+the end of the journey.
+
+The science based upon this subjective study of Nature is called
+metaphysics. Logic has been defined as "The Science of Thought;" it
+should be termed "The Science of Thinking." It is not a dead body which
+we are studying by dissection, but a living, vital Force, which we study
+by observing its activities. We find here the same error which we find
+elsewhere--a stopping with the material symbol, and an ignoring of the
+intellectual force which clothed itself with the symbol. Astronomy is
+not the science of circles and spheres, ellipses and ellipsoids, but of
+the Force whose sensible utterances are given in these curves. We might
+as well call Painting the science of pictures, or Sculpture the science
+of statues. So Language, the medium of thought, is only a symbol, less
+material indeed than pictures and statues, but still physical. What we
+want in "The Science of Thinking" is not the knowledge of symbols, but
+the knowledge of that which is symbolized. The chemist does not care for
+the compounds he finds in his retort; he seeks after the truth which
+these compounds formulate. Metaphysics and Physics evidently agree in
+this; that both are seeking to frame an articulate utterance of the Idea
+given in the diverse manifestations of Force--the Idea which includes
+all Potencies, the summing up of all phenomena into that final
+generalization which includes the intellectual as well as the material,
+until at last we reach the essential unity of all Truth.
+
+Science, then, is classification, or the discovery of the principles of
+classification, rather than an arbitrary acquaintance with things
+classified. Every science, however, must have an objective
+expression--that is, must be formulated. In this, both metaphysical and
+physical science agree; the only difference in this respect is, that in
+Physics, Nature gives us in the first place the material interpretation
+of the idea--that is, the basis of classification--which we have only
+to translate into idea: while in metaphysics, we first have the idea to
+which we must furnish the objective utterance. We see here the precise
+difference between what is called the logical and the natural
+method--the one being usually called the reverse of the other. The
+difference is not so much a difference in intellectual procedure as in
+objective expression. For instance: The botanist has before him the
+whole range of vegetable forms. He notes resemblances and differences,
+and groups plants into species and genera, but his work is not ended
+when these are named and known, and their qualities discovered. He is
+seeking amidst these multifarious forms for the law of vegetable growth
+and reproduction. Every organ of the plant is the symbol of an idea, and
+these ideas form the science of Botany. These Ideas are
+metaphysical--that is intellectual, and only their sensible
+manifestation is physical. The symbols of these Ideas, being given in
+Nature, must be learned from observation before they can be used
+intelligently, just as words must be learned before one can speak a
+language. Mastery of the means of expression is as essential to the
+communication of ideas an is the possession of the ideas themselves. The
+botanist observes an individual plant, and notes its characteristics. He
+observes others which possess some of these characteristics whilst
+others are wanting. He forms a class-type from these agreeing
+attributes, and gives this new collocation of characteristics a name.
+Nature never presents this class-type absolutely; it is found nowhere
+but in intellect. What has the botanist done but to retranslate the
+communication of Nature into Idea, and then to express this idea by less
+complicated and less physical symbols? Man's province in this case is
+simply to interpret the hieroglyphics of Nature into a more readily
+comprehended language--to express that simply which nature has expressed
+confusedly. The scientist restricts himself to the interpretation of a
+single class of symbols, as the Botanist to plants, the Zoologist to
+animals, but the end sought in each case is the same--that is, to
+change all these physical utterances of Nature into Idea, and to secure
+for this Idea a method of expression involving the least possible
+materiality of symbol--that is, to change individual facts and phenomena
+into general principles, which, because abstract, are unchangeable. When
+this has been done, the work of the Naturalist ceases, but the work of
+Man, the Thinker is not done; it is only just begun. By assuming the
+ultimate expressions of the various natural sciences as individual and
+not as typical, we can treat the truths reached by them precisely as the
+Botanist treated plants, and, rejecting points of of difference, may
+find in them all some central idea. This is the province of the
+metaphysician. He seeks the law of Idea, he determines the law of
+Thinking, just as all other laws are determined, from a study of the
+symbols formulating its expression in Nature. When this law has been
+distinctly enunciated, and freed from all intermixture with the
+contingent, then the work of the metaphysician ceases, the _summum
+genus_ has been reached. The truths communicated in the symbols of
+Nature, have been correlated and enunciated, and finally translated from
+the dialect of man the physical into the language of man the
+intellectual. Physical science determines the separate words of this
+message of God, the letters of which are scattered throughout Nature.
+Metaphysics combines these words into propositions which enunciate a
+distinct truth. There is therefore neither conflict nor variation
+between the method of Logic and the method of Nature. The movement of
+both is in the same direction; the only difference is in the point of
+starting. And another truth no less important, which follows from the
+foregoing discussion, is that the method of Nature is fundamental to the
+method of Logic. Physics should precede metaphysics, but not exclude it;
+both are essential to every true science, and physics, which stops with
+physics, leads man by dazzling promises into some Utopian desert only to
+leave him there to die of hunger. And it is no less true that
+metaphysics, without this basis in experimental science, is illusory
+and untrustworthy, wherever the original data are necessarily empirical.
+
+Two conditions are thus necessary to all science: a body of knowable
+truth capable of being systematized; and an intelligence capable of
+apprehending and systematizing it. One of these conditions is physical
+and one is metaphysical; and all true science must be the resultant of
+Law and Idea, the Objective and the Subjective, the twin forces of
+Nature and Man. If either of these conditions be wanting, there can be
+no true science, for science can neither be "evolved from the depths of
+the personal consciousness," nor can the scattered letters of scientific
+truth, as given in nature, arrange themselves into the words of a
+significant message. Knowledge must be classified before it is science,
+and that which classifies can only be intellect--discovering and
+enunciating this classification according to the laws of mental action.
+As prominence is given to one or other of these two conditions we have
+the division into Logical and Natural, but the fundamental principle of
+classification is the same in both--it being simply the law of
+intellectual action--just as the law which governs the action of the
+levers of a loom will determine the pattern of the woven fabric. There
+can, therefore, be no conflict between the methods of Logic and those of
+Nature. The determining element in all classification, whether of the
+phenomena of Mind or of the grosser phenomena of Matter is uniformly and
+always the same--the law of intellectual action.
+
+Science then resolves itself into a determination of this Law of mental
+activity, so that in an ultimate analysis, all science is metaphysical,
+just as all science primarily is physical. Here, as elsewhere, Law can
+be studied only in its objective manifestations. The Law of Thinking can
+be educed only from expressed Thought, but the Law is not objective
+thought, any more than the idea of the sculptor is marble, or the
+conception of the painter is paint. The simplest expression of thought
+is not the syllogism but the logical proposition. Now, it is plain that
+if the proposition is the formulation--the material representative of
+thought--if we study it as we study other natural symbols, we will find
+in it the fundamental Law of Thinking, and ultimately the fundamental
+Law of all Science: just as, if it were possible to reduce all
+elementary substances to one, the chemist would be able to find in that
+one a condensed expression of chemical science.
+
+What then is a proposition? Simply stated, it is the assertion of
+relation between two terms; or more abstractly, it is the reference of
+an individual to its species--the assertion of a classification. We find
+here the same duality which we noticed above. If we give prominence to
+the individual notion, we consider the proposition in extension; if we
+turn our attention to the specific notion we consider the proposition in
+intention: in the one case referring to the individuals composing the
+class, in the other to the attributes composing the class-type. The
+first corresponds to induction, the second to deduction. When we study
+individuals we study physics; when we study the attributes composing the
+class-type, we study metaphysics. The Law of Thinking as educed from a
+study of the proposition is the law of classification. The proposition,
+considered affirmatively, asserts explicitly agreement between certain
+attributes of two terms; that is, it asserts a classification. The aim
+of science is to reach this proposition, to discover and assert the
+principle of classification--in other words, to formulate metaphysically
+what nature has presented physically. We must find, then, the first or
+fundamental law of thinking in this _integration_ or classification.
+This fundamental law may be subdivided into two species, according to
+the two terms of the proposition; of which the first may be stated thus:
+"Every possible object of thought is to a certain extent identical with
+every other"; and as the proposition implicitly states disagreement, the
+second may be stated thus: "Every possible object of thought is to a
+certain extent diverse from every other." The first gives the positive
+(subjective) condition of the proposition, the second the negative
+(objective) condition: both together constitute the conditions of
+thinking. The proposition is thus the assertion of the same in the
+different. The proposition also asserts, implicitly, the _tertium quid_,
+or the basis of classification--the class-type, to which both terms are
+referred--that is, the proposition secondarily asserts an analysis.
+According to the first condition we have the inductive process;
+according to the second we have the deductive process. A complete
+movement of idea from its purely physical symbolization to its
+metaphysical interpretation, must involve both these processes.
+
+The mind possesses the power of analysis; it can watch its own
+operations and retrace its steps, until it arrives at the original data
+of consciousness; but analysis cannot comprise the whole of the logical
+process. Before there can be analysis there must be something to be
+analyzed; before steps can be retraced, they must be taken. We must not
+confound a condition with a Law--the one is a conception antecedent to
+all action, a genus to which the particular activity may be referred;
+the other is coincident with action. The one is the medium of the other.
+We may illustrate this idea by science itself, which is reached only by
+an analysis of Art. Matter is the condition of the expression of an
+idea; hence to all but the artist, Art must precede Science, but this
+cannot be in the case of the artist; in his mind the Idea is first
+conceived, and there it is given expression in the forms of Art. Here,
+as uniformly in Nature, the whole absolutely precedes the part--the
+universal exists before the particular--God before man. Truth absolute
+thus exists before truth conditioned. Science before Art. Remove
+conditions and the conditioned becomes the absolute; art and science
+coincide. But truth which is assumed to be out of all relations, cannot
+be comprehended by man, and practically is not. Even the universal
+propositions of deduction express universality under conditions--that
+is universality of relation; just as infinity in mathematics means that
+which passes measurement, while in fact between infinity and measurement
+there is no relation, and the infinite is thus incomprehensible as an
+object of thought, although by no means unrecognizable as a necessary
+condition antecedent to all intellectual action. It is of vital
+importance that we note this distinction, because reasoning, i. e.
+classification, is possible only so long as we deal with what is
+admitted to be under relation: if we assume a term to be out of all
+relation, it ceases to be an object of thought--it can neither be
+classified nor unclassified; it is beyond reason. Mathematics can
+proceed with its investigations only so long as it treats all quantities
+as measurable; it must wholly cease its calculations if an infinite term
+be introduced. To claim that analysis represents the complete normal
+action of the intellect in reasoning, is ultimately to claim that the
+initial point of thinking is the _summum genus_ of thought--God. Now God
+is undoubtedly the initial point of absolute thought, but he is not the
+beginning of human thought. Intellectually speaking, God is the final
+generalization; every movement possible to him must be one of
+analysis--a differentiation of Himself, so to speak, by negatives. Thus
+the course of absolute Thought, beginning with God, must be first
+towards a complete differentiation into ultimate individualization; and
+lastly a complete integration again of individuals into an infinite
+whole. This dual action completes the circle of intellectual activity.
+We have dropped attribute after attribute until we have reached the last
+possible analysis; but we do not stop here, but by the assumption of
+attributes we again reach the highest possible synthesis. This must be
+the method of the divine activity, successive differentiation and
+integration, the closing in of a mighty circle of infinity, embracing
+all the finite, but never losing the essential characteristic of the
+infinite.
+
+Now, if this also represent the exact movement of the finite mind in
+action--that is, in reasoning, man must be God. Man is finite. Even his
+infinite is only the immeasurable--not that which is without the
+category of measure. He cannot begin where the Infinite begins, at the
+highest possible generalization,--but he must begin with the finite. If
+what we have shown above be true, man must begin with the individual,
+and the first mental act of the positive character of thinking, is the
+reference of this individual notion to a class. Now the _class-notion_
+is the same as the individual notion, less certain attributes as
+_individual_ attributes, but gathered into a larger whole. This process
+is plainly integration; we are rejecting from the new conception
+whatever prevents enlarging the class. Each higher generalization
+involves all the attributes of the lower, not individually, but
+specifically or generically. In the final generalization, extension and
+intension coalesce. Just as we reach the individual by differentiating a
+universal through successive negations, we reach the universal again, by
+integration, by successively denying the negations through which we just
+now differentiated. The movement of the finite mind in reasoning is thus
+from the individual through the universal to the individual again.
+
+Science thus parts into two great branches--one seeking to establish
+principles by what we have called integration, and the other the
+elucidation of facts by _a priori_ reasoning instead of observation.
+That is, the aim of true science is to free man from the restrictions of
+the finite, and to place him in possession of the infinite--the closing
+in of a lesser circle of infinite truth, yet never losing hold upon the
+finite. In accordance with this view we see science pursuing its
+integrations until it has identified as composing an essential unity all
+the various manifestations of force. This is the finite becoming the
+infinite, for unity is, in so far, infinity--God is one, a unity, not a
+unit. But we also see science going beyond this point, and by a new
+series of differentiations reaching truths new to experience, if indeed
+not impossible to experience.
+
+Between these two limits all knowledge is forever moving. It can never
+rest. The tide of thought sweeps onward towards the infinite--God
+following it to its final absorption into the _I Am_, simple
+being,--while finite man, because of his finiteness, can only reach
+those universals which are infinite only to human thought. Like men on a
+journey we leave the train when we have reached our journey's end, but
+the train passes on out of sight in the distance, sending back, now and
+then, tokens of its progress, as it thunders over a bridge, or whistles
+shrill as it nears some further stopping place, until at last all is
+still, not because the train has stopped, but because we can follow it
+no further with our senses. Even after science has reached the utmost
+limit possible to it, it is not satisfied to rest there, but starts at
+once upon its return trip, to bring to notice undiscovered facts hidden
+in these mighty generalizations. Thus the pendulum of intellectual
+activity unceasingly vibrates between the infinite and the finite, never
+resting, because Idea and Matter, the force of Man and the force of
+Nature can never be completely identified.
+
+
+
+
+THE PHILOSOPHY OF EVOLUTION.
+
+
+The intellectual processes of a rational being must proceed according to
+some law. They cannot succeed each other at hap-hazard. The notion of
+rationality is conditioned upon this regular procedure; if this be
+wanting, the essential character of rational action is wanting. But to
+say that rational processes are determined by law, and conditioned upon
+a regular procedure, is simply to assert that the steps in ratiocination
+are so related to each other that the relation of each to every other
+may be determined by the application of the law--the difference between
+any two steps being analogous to the difference between any other two.
+The astronomer determines the orbit of a planet from three observations,
+because he thereby determines the law of variation between these points;
+from which he assumes that this law will be constant, presenting a
+series of terms each differentiated according the series of differences
+already determined.
+
+Applying the same principle to mental phenomena, we may determine the
+law of intellectual action. Thoughts are discriminated by the presence
+or absence of certain attributes. At one extreme we find the _summum
+genus_, comprising the fewest possible attributes distinguishing an
+idea; at the other extreme we find the individual, comprising any number
+of attributes. Between these two extremes we find a regular series of
+intermediate terms. The movement of an idea from the general to the
+individual is like the motion of a planet through one-half of its orbit;
+while the return movement from the individual to the general,
+corresponds to the motion of the planet over the remaining half of its
+orbit. The same law governs both movements and unites the two halves of
+the orbit into a single whole; and a series of observations taken at
+equal distances, will, by the uniformity of differences presented,
+reveal the operation of the same law in this dual manifestation. Upon
+examining the processes of deduction and induction, we find in each the
+same series of terms, differing only in the fact that they are in
+inverse order, and this correspondence reveals the operation of one and
+the same law. An inductive series is only a deductive series read
+backward. Any two terms in a series whether inductive or deductive,
+differ only in the degree of generality, and differ similarly from a
+third term, so that two being known the third can be therefrom
+determined. In a deductive series the terms differ by a constant
+increase in the number of individualizing attributes--a concept being
+expanded into a deductive series by such regular additions. Having two
+terms we can proceed to the third--that is, from two propositions
+expressing this relation, we can proceed to a conclusion. In an
+inductive series the terms differ by a constant diminution in the number
+of individualizing attributes--an individual term being expanded into an
+inductive series, by successively dropping the attributes which compose
+the individual term, until we reach the required degree of
+generalization.
+
+Thought must proceed in one of these two directions. The object-matter
+of thought being composed wholly of attributes can differ only in the
+presence or absence of certain attributes. A combination, then, of these
+two movements must complete the intellectual orbit. The direction of the
+movement of the mind will be determined by the end proposed. When we
+possess the knowledge of phenomena and wish to discover law--that is,
+when we seek information--we proceed by induction, from the individual
+to the general. When possessed of knowledge, we wish to discover its
+applications, when knowing the law, we wish to determine the phenomena
+necessarily resulting therefrom, we proceed by deduction--from the
+general to the individual. Complete knowledge, then, consists in the
+highest possible generalization, and the expansion of this term into a
+series, ending only with the last possible individualization. The aim of
+physical science is to determine that half of the intellectual orbit
+which lies between the individual and the general--the aim of
+metaphysical science is to trace the other half which lies between the
+general and the individual. When we seek to know what is, we proceed by
+induction--the method of the phenomenal. When, knowing what is, we
+proceed to determine what hence must be, we proceed by deduction--the
+method of the Necessary. Thus Science, at first seeking principles,
+proceeds by induction to establish them; but after these fundamental
+principles have been established, it proceeds deductively to determine
+what must result from them, without waiting to discover these truths by
+observation.
+
+Knowledge is thus complete just in proportion to the extension of its
+scope through generalization. The higher the generalization, the more
+inclusive will it be, and the _summum genus_, or the final
+generalization, will be the highest attainable reach of knowledge. When
+man can make no further generalization, his knowledge will be, in so
+far, absolute and complete, and all that remains possible to him will be
+the practical application of what he already knows. Perfect knowledge is
+nothing but perfect generalization. The Supreme Intelligence being
+hypothetically possessed of all knowledge, that is, having discriminated
+the absolute _summum genus_, can proceed no further in this direction;
+his intellectual activity must be exerted in a descending series, or
+from the general towards the individual, and this process must be, as we
+have seen above, by a determinate series of steps, fixed by the
+operation of a definite law, which law proceeds by the successive
+addition of attributes to the general.
+
+Complete knowledge, being complete generalization, the lines of all
+science will necessarily converge, as they approach this generalization,
+until all sciences coalesce in one science, and all truth is reduced to
+a single expression in the utterance of the final conception. In
+accordance with the laws of thinking, this general term is reached by
+successive omissions of particularizing attributes, until at last we
+reach Being--the absolute _summum genus_, wholly free from individual
+attributes, and thereby embracing everything possible to thought,
+whether material or immaterial. But this _summum genus_ must be
+predicable of this whole. Matter and mind may thus be reduced to a
+single category, and the physical and the intellectual finally coalesce
+in this last generalization. Materialism and idealism thus differ merely
+in the degree of generalization reached--or rather they both agree in
+avoiding the final generalization which identifies both matter and mind.
+Materialism must always deal with the individual, for matter can appear
+under no other form. Idealism must always rest upon the general, for
+thought, to be thought, must state a generalization. Each, however,
+finds its explanation in the other, and both are harmonized by the
+application of the law of intellectual action above given. Matter and
+Mind are complementary, not incompatible. They differ with each other,
+but they agree in being similarly related to a third term. Matter is
+objective; it is thought taking form, becoming individual, manifesting
+itself in space. Mind is subjective. The one appeals to the senses; the
+other is known only to the consciousness.
+
+Science reaches its full development only when it includes both physical
+and intellectual phenomena within its scope. Every step which it takes
+carries it further from the purely physical, and brings it nearer the
+purely intellectual--that is the development of physical science is from
+the individual towards the general, and it reaches its end, its
+completion, only when the last distinction, that of subjective and
+objective, has disappeared in the last possible generalization. When the
+objective has been identified with the subjective, the distinction
+between Mind and Matter has been obliterated, and we have reached the
+Supreme Intelligence--the "I Am" of Scripture--simple Being.
+
+Matter is the formal expression of thought, or the necessary condition
+of such expression, and in this condition is found the link that
+connects the subjective and objective manifestations of _being_.
+Subjectivity is ideality, as objectivity is materiality. The
+consciousness can take cognizance only of what is within itself, and
+therefore without every other. Consciousness is therefore wholly
+personal. To communicate an idea it must be placed within the
+consciousness of another. To reach this result it must cease to be
+personal, must pass out of the subjective consciousness into objective
+form, so as to be placed in the same relation to the speaker and the
+hearer. Thought, out of the consciousness of the thinker, is objective
+to him, and to render thought objective is to give it material form.
+Thought to be communicated, must pass out of the consciousness of the
+thinker into a material representation. The assumption of material form
+individualizes the idea. The artist's mind may be filled with splendid
+conceptions, but no one but he can look within his consciousness and see
+them. Before others can have any knowledge of his thoughts, he must give
+them form, or embody them in statues or paintings. The soul of the
+musician may be thrilled by the harmonies that his imagination creates,
+but no other soul can join him in this ecstasy until he has given form
+to his conceptions. So the thinker must embody his thoughts in language
+before he can communicate them to another. Matter, then, is the vehicle
+by which thought is communicated, and, so far as we are concerned, the
+necessary condition of such communication, so that the conception of
+thought apart from the thinker involves the intervention of material
+forms, and it is by the interpretation of these symbolical forms that we
+discover the idea.
+
+Now, let us suppose a Supreme Intelligence. The intellectual processes
+of such a Being, to be conceived as rational by us, must be identical
+with ours, or at least analogous to ours. The possession of infinite
+attributes may in fact free him from the control of any law, but it is
+impossible for us to conceive an intelligence acting otherwise than in
+accordance with law. So that if the Supreme Intelligence is to
+communicate with man, it must be in obedience to the laws which control
+our mental activities. The Divine thought must, then, like human
+conceptions, be communicated by means of physical symbols.
+
+The Supreme Intelligence, being the final generalization, must possess
+all knowledge, and the only intelligent action possible to him from our
+point of view, is from this absolute generalization towards the concrete
+and individual. The absolute general is purely subjective, which, to
+become cognizable, must be rendered objective. This can be secured to us
+only through the intervention of material forms. From this point of
+view, matter is only the symbol of thought--thought apart from the
+thinker. The first result of the divine activity in self-manifestation
+would be the analysis of _being_ into subjective and objective--that is
+the discrimination of mind and matter, which terms are severally the
+final generalizations of the two fundamental divisions of science.
+Matter, then, mere formless, chaotic matter, would be the first result
+of creative activity. Following the development of this idea in its
+continually increasing individuality, as new attributes are severally
+added, matter assumes determinate form and becomes related in systems,
+as the various so-called elementary substances are discriminated, until
+finally all truth, capable of being revealed by inorganic matter, is
+presented to us.
+
+Add the idea of organism and we have the two great divisions of
+phenomena--material and vital. The higher the generalization, the fewer
+will be the attributes composing the concept, and thus the simpler will
+be the form symbolizing its expression. As in the case of matter, the
+first result of the divine activity was more matter, undiscriminated by
+any further attribute; so here, we have, as the first organic creation,
+a concrete expression of the highest possible generalization comprising
+the fewest possible attributes--that is, forms of life involving the
+fewest individual characteristics. To matter add the simplest organic
+attribute--that is, the one lying nearest the genus--and we have mere
+organized matter, the simple cell, the foundation of all life, no matter
+how great its future complexity, equally the origin of animal and
+vegetable growth, which are as yet entirely undiscriminated. This would
+be the first appearance of life.[1] Differentiating again by the
+addition of a new attribute, and organic being is subdivided into the
+two species, vegetable and animal. Beginning with these typical forms,
+adding single attributes in a continuous series, we at last reach the
+highest types of animals and plants. Finally, add rationality to the
+animal, and we reach man, the highest and therefore the most complex
+type of life, and who, so far as we are concerned, must be the end of
+creation. We cannot conceive of any higher creation, because we cannot
+add an attribute to those we already possess, any more than we can
+conceive of an additional sense by which to cognize such new attribute.
+
+This process has been determined from the very outset by those
+intellectual laws which we cannot disobey, and which we cannot conceive
+disobeyed by an intelligent creator. If the law of intellectual action
+require this process from the simple to the complex, the concrete
+representation of the steps of this process must indicate the operation
+of this law, and must also proceed from the simple and rudimentary to
+the complex and highly developed. An intelligent Creator in revealing
+his thought must follow the method which our minds must follow in
+interpreting this revelation. When we know and seek to communicate our
+knowledge, we proceed from the general to the specific.[2] The Creator
+assumed to be infinite in knowledge would therefore follow this process
+instead of the method peculiar to investigation. The law of intellectual
+action determines this method, and the conditions of intellectual
+communication determine the representation of this method in the
+material expression of the ideas communicated. Considering the operation
+of this law under these conditions, we find that the thought
+communicating only, as nearly as may be, the generic idea, will be
+distinguished from it by the addition of but a single attribute as the
+generic by itself is incapable of being represented in concrete form,
+the expression of this thought in form will present us matter
+distinguished from matter in general by but a single attribute. The
+least possible individualizing attribute added to the highest possible
+generalization gives us the simplest expression of an idea, and the form
+or the organism symbolizing this thought will be the simplest form and
+the simplest organism possible. For instance: in organic life the
+highest generalization barely individualized will give us the simple
+cell; and no matter what degree of complexity we subsequently reach by
+the addition of an almost infinite number of attributes, we nevertheless
+begin in every case with the same starting point.
+
+Each higher type is reached by adding to a lower. The higher thus
+embraces all that can be found in the lower, and something besides. This
+method is invariable, and can never be departed from. The genus must
+always be predicable of every individual component of every species
+contained under it. Translating this law into the forms of material
+expression, and it requires each higher species to physically include
+all lower species, and to differ from them only by addition. Man, the
+highest type, must thus include all the attributes of the cell as
+physically expressed, and without them he would not be man. The
+differences between no two terms in a series can be total. If the
+successive steps in a train of thought must be related, so that no two
+notions will be wholly distinct from each other, these notions will
+constitute a series, each term of which will, in a measure, determine
+the next, so soon as the law of the series is discovered; and if this
+train of thought be objectively presented, it will afford a
+corresponding series of physical terms, each one of which will in like
+manner determine the next. But thought is impossible unless by a train
+of ideas so related. Its physical expression will therefore be equally
+impossible except by a series of physical terms similarly related, each
+one of which in some manner determines the next. There must then be a
+perfect continuity in the line that reaches from the simplest form of
+matter through all grades of organic life up to man, the highest
+expression of the divine idea. There can be no break in the chain of
+thought, because the law of the logical process forbids it: there can be
+no break in the series of material symbols for the conditions of
+concrete expression equally forbid it. A symbol is nothing except as it
+represents that which is to be symbolized. So the symbols form a
+physical series, because the thoughts symbolized form a logical series.
+
+If the creator has fully revealed his thought, it must be by a series of
+physical terms arranged in such a manner as to indicate the logical
+series of ideas symbolized. Every form of matter is a symbol of thought,
+and challenges interpretation. Every change in form corresponds to an
+antecedent change in idea, and must be intended to reveal it. As
+thought, then, begins its evolution with the general and proceeds to the
+individual by a series of terms each of which is similarly related to
+both extremes, we must find the material enunciation of this process
+assuming the form of a series of terms, beginning with mere nebulous
+matter, grading into organic life, and organic life presenting us with a
+similar series beginning with the mere cell and ending with man. So
+rigid and invariable must this serial arrangement be that if a term in
+either series be wanting, we are authorized to hypothetically
+interpolate it.
+
+"Nature never makes a leap," says the scientific investigator, as he
+studies the material symbols of thought. "Thought never makes a leap,"
+says the metaphysician, as he studies the necessary laws of rational
+action: and both have uttered the same truth. We prove a proposition by
+determining the steps by which it was educed from a more generic
+statement. Science must proceed in the same manner, for science only
+discovers the track of mind--it does not make the track, it only follows
+it. If then we find the chain of evolution broken at any point, science
+must either stop there, or assume the wanting term in the series. We
+have the right to interpolate these missing terms, for we must assume
+that the thoughts of God communicated to us in material forms constitute
+a continuous revelation, beginning with Himself, the final
+generalization, and ending with man the highest individualization. These
+limits are fixed--the one by the nature of God, and the other by the
+nature of man. Between these two extremes we must find a series of
+intermediate terms. Any other conception of their relation than that of
+a determinate series is impossible and irrational; and a series, so far
+as it means anything, means evolution of some sort. Finding the relation
+between these terms--distinguishing the _same_ which reproduces itself,
+and the _different_ which introduces a new term--that is, determining
+the law of apparent evolution--is the problem presented to science.
+
+The astronomer found Bode's law to all appearance violated by the
+omission of a planet between Mars and Jupiter. He could see no reason
+for the law, but if the planets had been placed by an intelligent
+Creator, some order of arrangement must be discoverable according to
+which their position was determined. The Creator being intelligent, it
+is impossible to conceive them placed fortuitously. There must then be a
+link between Mars and Jupiter, because the law once established cannot
+be broken. The same law may be observed in the arrangement of leaves
+around the axis of a plant. If intelligence arranged them they must be
+arranged in some order, for intelligence never performs the least act
+without a purpose. Each leaf or pair of leaves is not a mere duplication
+of the previous leaf or pair of leaves. The relation which subsists
+between any two sets in the series expresses the idea of the Creator,
+and this must be constant. Completing the series as indicated by
+different plants, we may assume that if any term is apparently wanting,
+it is only because it has not been discovered. In neither of these cases
+would it be asserted that any physical evolution had taken place--the
+terms form a series of which each term is equally determined by the
+operation of a fixed law; and yet it is an operation precisely analogous
+to that which in the case of animals presents every appearance of a real
+evolution. Take, for instance, a series of animals, presenting at one
+period of time the simplest and most rudimentary forms, and at another
+the most complex and highly organized; we cannot do otherwise than
+conceive these two extremes as related by intermediate terms, through
+the operation of some law which holds good throughout the series. The
+relation subsisting between any two, must be the same as that subsisting
+between any other two similarly situated, or a departure from that
+relation which is itself governed by a definite law discoverable from a
+comparison of two sets of terms. The application of this law is so
+universal and so rigid that we need not hesitate to interpolate a
+missing term, and confidently assert that it either does exist or has
+existed. To deny this principle is to deny the necessity of continuity
+in reasoning. This continuity of thought is represented in matter by the
+persistence of generic forms under specific differences. But just as the
+specific is the generic with certain additions, so the individual is
+this same generic with still further additions; and these additions,
+whether considered solely in space, as given in the symbols of physical
+science, or in time as in the conceptions of intellectual science, must
+be determined by the same unvarying law. The persistence of the same
+form furnishes us the means of identifying this relation, while the
+differences reveal to us the successive steps by which the generic was
+differentiated into the individual.
+
+If the creative thought has been expressed by the forms of matter, the
+laws of thought must be thus expressed in the relative forms of matter.
+Anything less than this, while it might interpret isolated ideas, would
+not communicate the method of the creative process, and science is
+nothing but the discovery of this method. If the terms of the logical
+process must be arranged in a series, the physical symbols rendering
+this logical process cognizable, must be arranged in a similar series,
+for science becomes impossible when the logical process becomes
+undiscoverable.
+
+The differences between the terms in this series must be cognizable. Two
+terms which are indistinguishable are practically identical; and two
+terms which are not identical vary by a difference which is cognizable
+by itself apart from either term. The steps in the logical evolution of
+the final term. _Being_ must be separable to be cognizable, and the
+material forms interpreting these steps to the senses must also be
+distinguishable. A species differs from the genus by the addition of at
+least one attribute. Now, if the species is distinguishable from the
+genus, the attribute which differentiates it, must be separately
+cognizable--so also the individual differs from the species by the
+addition of attributes, which must in like manner be separately
+cognizable, or the species will never be conceived independently of the
+individuals. A thought cannot proceed by insensible steps, nor can its
+material expression vary otherwise than by determinate and
+distinguishable differences. The distinction of species is thus a
+logical necessity. The addition of distinct attributes to the genus
+gives origin to distinct species; variation in attributes not affecting
+their substantial identity gives rise to varieties. One species, then,
+cannot become another, except by the assumption of a new specific
+attribute, so that one species passes into another precisely as the
+genus passes into the species, and that is just as, and not otherwise,
+than one thought passes into another.
+
+The fundamental law of the logical process is that we pass from the
+generic towards the individual; from the simple to the complex.
+Induction can proceed only by assuming a genus at the outset--that is,
+by assuming certain attributes in the individual to be generic.
+Translate this law into material forms, and we have each higher--that is
+more complex--species evolved from the lower by the addition of some new
+characteristic. This new attribute cannot be added by the functional
+activity of the lower organism; that can only reproduce itself. A
+thought does not change merely through repeated expression. We pass to
+the conclusion of a syllogism, not from each term, but from a comparison
+of the premises--and this requires an intellectual operation entirely
+distinct from a mere apprehension of the terms. It is one thing to
+comprehend the premises; it is quite another to deduce a conclusion from
+them. It may necessarily follow, but it requires a separate act of the
+mind to reach it. Premises will not of themselves reach a conclusion.
+
+Reading this same truth in the forms of matter, we may say that species
+will not pass into higher species without the intervention of a force
+distinct from either. The impulse which adds a new attribute must be
+intellectually separable from all those pre-existing, and its material
+representation must be physically distinct from pre-existing forms. This
+complete separability precludes the possibility of mere physical
+genesis. The added attribute is presented by a new form of matter,
+revealing the presence of a new thought--a new effect, requiring the
+agency of a new cause. In accordance with the usual economy of nature,
+who never duplicates her forces, change will be made only so far as may
+be necessary to communicate the additional idea. Organisms representing
+previous thoughts will be added to, in order to express the expansion of
+the thought, instead of a creation _de novo_ in each instance. Thus an
+identical cellular structure will be found in all organic beings, from
+the lowest to the highest, each higher type carrying forward the idea
+and its physical expression found in the lower. The differences between
+no two terms in the series can be total, nor can any two terms be
+identical, as each higher species will embrace all the attributes of the
+lower, differing only by the addition of others. This is simply the
+physical expression of the logical truth that whatever can be predicated
+of the genus can be predicated of every individual contained under it.
+As the individual is only the expansion of the genus, so higher physical
+types must also be similar expansions of lower.
+
+Here, then, is evolution, or development: primarily an evolution of the
+generic into the individual, the continued differentiation of a generic
+idea through successive individualizations, each adding to the previous
+group of attributes, thus rendering the idea increasingly complex; and,
+secondly, an apparent physical evolution or development, interpreting
+this logical process by a series of physical forms so related as to
+reveal the relation existing between the thoughts thus interpreted. In
+the physical representation of the ideas so related, there must be an
+apparent physical evolution--that is, the process of evolution logically
+must, like the ideas thus evolved, have a physical expression, and the
+successive steps in this logical evolution must be revealed by material
+forms bearing an analogous relation, and thereby expressing the logical
+process. Matter is nothing, so far as we are now concerned, but the
+condition necessary to the objective expression of thought. Every phase
+of matter is simply an objective formulation of a corresponding phase of
+thought. Every addition to form implies an antecedent increase of
+thought, as there can be no formal expression until there is something
+to be expressed. There can, then, be no such thing as mere material
+evolution, for whatever is material is only symbolical.
+
+Matter being thus wholly inert, the origin of the impulse towards
+greater complexity must be sought for outside of that which undergoes
+the change. The movement by which one species becomes a higher is not an
+elaboration, an extension or a differentiation of existing attributes,
+but involves the positive addition of a new attribute, different and
+distinct from any or all previously existing. One species cannot pass
+into another by an innate impulse, for a species is an entity composed
+of a determinate number of attributes, and all attributes potentially
+present must be considered as actually present. We cannot say that the
+child is a different species from the man, and that one passes into the
+other by a process of evolution, because all the essential attributes of
+the man are potentially present in the child. If the polyp, by the
+action of innate forces, operating through a series of ages, however
+extended, can, without any impulse from without, develop itself into a
+man, then the polyp is as much a man as a boy is, differing only in the
+time required for development: and the data for the final deduction of
+the highest types of creation must be furnished in the most elementary
+forms of life.
+
+The force manifesting itself in organic life is readily distinguishable
+from the organism by which it is manifested. Life and organization are
+not synonyms; one is the condition of the other, but a condition is not
+a cause. We can consider force apart from organism, and this possible
+separation in thought proves that the same form may not represent both,
+but that life can absolutely exist apart from organs which serve to give
+it a physical manifestation.[3] Physical life being conditioned upon
+organization, whenever the organism varies, the vital force thus
+manifested must also vary, such variation being necessarily antecedent
+to its manifestation. The organism varies, because it must, in order to
+express the added thought. Change in organism, therefore, is not induced
+by simple organic action, because the organs and the force acting
+through them can be distinguished. Assuming that matter is the objective
+or formal representation of thought, there can be no change in the
+material expression without a corresponding change in the antecedent
+conception. There can, then, be physical evolution, only as there is
+antecedent logical evolution, and then only because of this logical
+evolution and not because of the operation of an innate organic force.
+Force, whatever may be its genesis, is only the exertion of power, not
+the increase of it. Exertion limits the view to the force immediately in
+operation. We may replace one manifestation by another, but the quantity
+is neither increased nor diminished by this change. Change in form
+implies the operation of force: and apart from such manifestation in
+matter, it escapes the tests of science, and passes into the purely
+metaphysical notion of cause. And unless the operation of force be
+constant, or, if different forces are blended, variable according to
+some determinate law, the action of which is constant and discoverable,
+so that the different units of force are separately measurable, the
+force thus irregular in its action can never be placed in any scientific
+category. Evolution, then, cannot proceed from any innate organic
+impulse, unless the force that tends to exact reproduction, and the
+force that induces a change be equally and separately cognizable. Change
+must proceed according to some law which accounts for the change, and
+distinguishes between the normal exertion of power and that exertion
+which causes a deviation. Science, to be science, must explain apparent
+exceptions as fully as the regular operation of forces, and that which
+causes the irregularity must be as distinctly cognizably by itself as
+the force which acts regularly. Anything less than this is not science.
+The discovery of Neptune was the result of the application of this
+principle; it was a successful attempt to discriminate the force which
+caused variation from the force which operated regularly.
+
+Each species represents the operation of certain vital forces, and one
+cannot physically pass into another except by the increase of this
+force, or at least by a change in the manner of its manifestation; and
+this increase in amount or this change in direction must separately be
+accounted for. Nor does it matter, for the purposes of this discussion,
+as to the genesis of this added increment, further than to show that its
+origin must be exterior to the organism by which its presence is
+manifested; for vital energy acting through an organism is a unit, and
+cannot, even in thought, be separated into distinguishable portions.
+Change in the direction of vital energy indicates that the original
+impulse has been modified in its action by encountering another force,
+for nothing but force can change the direction of force. It does not
+fall within the range of this paper to determine the nature of this
+exterior force which is thus distinguishable from that acting through
+the vital organization, and therefore capable of separate objective
+representation. Metaphysically we may say that force is resolvable into
+will, but will being purely personal is incapable of material
+representation, and thus cannot enter into the determinations of
+physical science, which does not seek to discover the origin of force,
+but deals solely with its presence.
+
+As the logician must assume his premises, and, as a logician, cannot
+question their truth, so the physicist must assume a force in operation,
+and, as a physicist, cannot examine its genesis. The physical or the
+metaphysical method of inquiry is valid only so long as restricted to
+physical or metaphysical processes: a mixture of the two methods will
+give results satisfactory neither to science nor to philosophy. As logic
+furnishes no criterion by which to test the absolute truth of
+propositions, but deals wholly with conclusions drawn from given
+premises, so science furnishes no data by which to determine the
+absolute genesis of force, but restricts its enquiries to the phenomena
+resulting from a force given. For the student of physical science cause
+and effect is only the transference of a given and determined force from
+one material form to another. If this idea is to be traced further, it
+must be studied outside the limits of physics. This study belongs to
+metaphysics.
+
+Now, if physical science does not deal with the origin of the initial
+force, but assumes at the outset its presence, no more does it fall
+within its province to examine into the origin of the increments which
+give to physical forms that variety which renders science possible.
+Science deals with results, not antecedents; and after having determined
+results, it is not authorized to affirm that one species has produced
+another by evolution, or has produced it at all. If there are agreements
+between different organisms by which they are brought into relation,
+there are also differences by which they are discriminated, and these
+differences imply increments of force; and to assert that one organism
+has evolved another is to determine not merely the presence of this new
+increment, but also to determine its origin. Scientific investigation
+deals with phenomena which give evidence to the senses of a
+_transference_ of force from one form or from one manifestation to
+another. Transference is not increase--an effect can be no more than the
+evolution of what was potentially present in the cause; it cannot add to
+it. The origin of the force must be investigated according to
+intellectual laws.
+
+
+It has been argued that a Supreme Intelligence in manifesting his
+thought will, according to the necessary laws of rational activity, pass
+from the universal and general to the particular and individual, or from
+concepts involving few attributes to those involving these and others;
+and that these steps in the rational process must be represented in a
+corresponding physical series; and that the communication of thought is
+conditioned upon this physical representation. If the logical series
+comprises one thousand terms, each related to the preceding according to
+logical law the physical series must comprise one thousand terms, each
+physically related in such a manner as to reveal this law. As the
+highest generalization comprises the fewest attributes, the concrete
+expression of this idea will present the simplest possible physical form
+and the least complexity of organization, and thus will present the
+lowest types of life; and as the individual comprises the greatest
+number of attributes, its concrete expression will present the greatest
+complexity, and consequently the highest type of life. We have seen
+that the logical process begins with the general and ends with the
+individual; its material expression must therefore begin with the lowest
+orders and end with the highest. But the individual cannot be
+immediately derived from the general without the intervention of
+intermediate generalizations. No more in the concrete expression of this
+deduction can we pass from the lowest types to the highest without the
+intervention of an intermediate series. These intermediate terms are not
+capable of independent interpretation; they find their full explanation
+only in the extremes of the series--God and Man.
+
+If, then, in the intellectual process from the abstract and universal
+towards the concrete and individual, we find a constant evolution of
+idea, each advance being an addition to the previous conception, each
+new term in the series embracing all the attributes of the preceding,
+and differing only by addition; and if thought is possible only on this
+condition; it necessarily follows that the material representation of
+this thought must present physical forms similarly related, so that,
+leaving out of view the intellectual genesis of this relation, the
+observer might conclude that these forms compose a series evolved from a
+primordial cell in accordance with an organic law. But such we find to
+be the universal law of intellectual procedure: this apparent
+development or evolution must, therefore, be the condition of the
+communication of such intellectual process, and the physical terms are
+brought into this relation by the fact that they symbolize the logical
+process. If the material symbols of thought were unrelated physically,
+the thoughts thus expressed would also be unrelated and independent. But
+such a supposition readers Science impossible, for its one aim is to
+find the _same_ in the _different_. If there be no _same_, there can be
+no science: if there be no _different_, there can be no science. Thought
+proceeds by adding the _different_ to the _same_ in an endless series,
+and this addition of the _different_ to the _same_ expressed in concrete
+forms is what is called evolution. If no evolution were apparent in
+Nature, there could be no Science; for those steps which to the
+naturalist indicate evolution, being only the physical expression--the
+formulation--of the logical process, afford the means by which the
+student reaches the highest generalization. If these steps be wanting,
+he cannot proceed.
+
+Admitting then to its fullest extent the fact that, judged from a purely
+physical point of view, all organic forms seem to have been derived each
+from its immediate predecessor, by a mere functional impulse; and
+admitting that science is possible upon no other condition; we claim
+that these material forms are brought into such relation by intellectual
+evolution, and not by physical genesis; they represent an evolution of
+Thought and not an evolution of Matter. We know from consciousness that
+this process of evolution is the method of our thinking. We know also
+that the divine thought can be rendered intelligible to us upon no other
+hypothesis than that which supposes it to be governed by the laws which
+control human thought. Translating the physical symbols which we see
+about us, and which present this appearance of evolution, we infer that
+this is the method according to which the divine mind proceeded. Science
+will not materially err in its physical results, if it adopt the
+hypothesis of physical evolution, but it must confine its attention to
+physics; it is only as we attempt higher generalizations that the
+insufficiency of the hypothesis becomes manifest in its failure to
+satisfy the conditions of the problem as presented to philosophy.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.

+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate

+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
