PART II CRITIQUE OF THE TELEOLOGICAL JUDGEMENT (continued 2)

Just as Reason in the theoretical consideration of nature must assume the Idea of an unconditioned necessity of its original ground, so also it presupposes in the practical [sphere] its own (in respect of nature) unconditioned causality, or freedom, in that it is conscious of its own moral command. Here the objective necessity of the act, as a duty, is opposed to that necessity which it would have as an event, if its ground lay in nature and not in freedom (i.e. in the causality of Reason). The morally absolutely necessary act is regarded as physically quite contingent, since that which ought necessarily to happen often does not happen. It is clear then that it is owing to the subjective constitution of our practical faculty that the moral laws must be represented as commands, and the actions conforming to them as duties; and that Reason expresses this necessity not by an “is” (happens), but by an “ought to be.” This would not be the case were Reason considered as in its causality independent of sensibility (as the subjective condition of its application to objects of nature), and so as cause in an intelligible world entirely in agreement with the moral law. For in such a world there would be no distinction between “ought to do” and “does,” between a practical law of that which is possible through us, and the theoretical law of that which is actual through us. Though, therefore, an intelligible world in which everything would be actual merely because (as something good) it is possible, together with freedom as its formal condition, is for us a transcendent concept, not available as a constitutive principle to determine an Object and its objective reality; yet, because of the constitution of our (in part sensuous) nature and faculty it is, so far as we can represent it in accordance with the constitution of our Reason, for us and for all rational beings that have a connexion with the world of sense, a universal regulative principle. This principle does not objectively determine the constitution of freedom, as a form of causality, but it makes the rule of actions according to that Idea a command for every one, with no less validity than if it did so determine it.

In the same way we may concede thus much as regards the case in hand. Between natural mechanism and the Technic of nature, i.e. its purposive connexion, we should find no distinction, were it not that our Understanding is of the kind that must proceed from the universal to the particular. The Judgement then in respect of the particular can cognise no purposiveness and, consequently, can form no determinant judgements, without having a universal law under which to subsume that particular. Now the particular, as such, contains something contingent in respect of the universal, while yet Reason requires unity and conformity to law in the combination of particular laws of nature. This conformity of the contingent to law is called purposiveness; and the derivation of particular laws from the universal, as regards their contingent element, is impossible a priori through a determination of the concept of the Object. Hence, the concept of the purposiveness of nature in its products is necessary for human Judgement in respect of nature, but has not to do with the determination of Objects. It is, therefore, a subjective principle of Reason for the Judgement, which as regulative (not constitutive) is just as necessarily valid for our human Judgement as if it were an objective principle.

§ 77. Of the peculiarity of the human Understanding, by means of which the concept of a natural purpose is possible

We have brought forward in the Remark peculiarities of our cognitive faculties (even the higher ones) which we are easily led to transfer as objective predicates to the things themselves. But they concern Ideas, no object adequate to which can be given in experience, and they could only serve as regulative principles in the pursuit of experience. This is the case with the concept of a natural purpose, which concerns the cause of the possibility of such a predicate, which cause can only lie in the Idea. But the result corresponding to it (i.e. the product) is given in nature; and the concept of a causality of nature as of a being acting according to purposes seems to make the Idea of a natural purpose into a constitutive principle, which Idea has thus something different from all other Ideas.

This difference consists, however, in the fact that the Idea in question is not a rational principle for the Understanding but for the Judgement. It is, therefore, merely the application of an Understanding in general to possible objects of experience, in cases where the judgement can only be reflective, not determinant, and where, consequently, the object, although given in experience, cannot be determinately judged in conformity with the Idea (not to say with complete adequacy), but can only be reflected on.

There emerges, therefore, a peculiarity of our (human) Understanding in respect of the Judgement in its reflection upon things of nature. But if this be so, the Idea of a possible Understanding different from the human must be fundamental here. (Just so in the Critique of Pure Reason we must have in our thoughts another possible [kind of] intuition, if ours is to be regarded as a particular species for which objects are only valid as phenomena.) And so we are able to say: Certain natural products, from the special constitution of our Understanding, must be considered by us, in regard to their possibility, as if produced designedly and as purposes. But we do not, therefore, demand that there should be actually given a particular cause which has the representation of a purpose as its determining ground; and we do not deny that an Understanding, different from (i.e. higher than) the human, might find the ground of the possibility of such products of nature in the mechanism of nature, i.e. in a causal combination for which an Understanding is not explicitly assumed as cause.

We have now to do with the relation of our Understanding to the Judgement; viz. we seek for a certain contingency in the constitution of our Understanding, to which we may point as a peculiarity distinguishing it from other possible Understandings.

This contingency is found, naturally enough, in the particular, which the Judgement is to bring under the universal of the concepts of Understanding. For the universal of our (human) Understanding does not determine the particular, and it is contingent in how many ways different things which agree in a common characteristic may come before our perception. Our Understanding is a faculty of concepts, i.e. a discursive Understanding, for which it obviously must be contingent of what kind and how very different the particular may be that can be given to it in nature and brought under its concepts. But now intuition also belongs to knowledge, and a faculty of a complete spontaneity of intuition would be a cognitive faculty distinct from sensibility, and quite independent of it, in other words, an Understanding in the most general sense. Thus we can think an intuitive Understanding [negatively, merely as not discursive118], which does not proceed from the universal to the particular, and so to the individual (through concepts). For it that contingency of the accordance of nature in its products according to particular laws with the Understanding would not be met with; and it is this contingency that makes it so hard for our Understanding to reduce the manifold of nature to the unity of knowledge. This reduction our Understanding can only accomplish by bringing natural characteristics into a very contingent correspondence with our faculty of concepts, of which an intuitive Understanding would have no need.

Our Understanding has then this peculiarity as concerns the Judgement, that in cognition by it the particular is not determined by the universal and cannot therefore be derived from it; but at the same time this particular in the manifold of nature must accord with the universal (by means of concepts and laws) so that it may be capable of being subsumed under it. This accordance under such circumstances must be very contingent and without definite principle as concerns the Judgement.

In order now to be able at least to think the possibility of such an accordance of things of nature with our Judgement (which accordance we represent as contingent and consequently as only possible by means of a purpose directed thereto), we must at the same time think of another Understanding, by reference to which and apart from any purpose ascribed to it, we may represent as necessary that accordance of natural laws with our Judgement, which for our Understanding is only thinkable through the medium of purposes.

In fact our Understanding has the property of proceeding in its cognition, e.g. of the cause of a product, from the analytical-universal (concepts) to the particular (the given empirical intuition). Thus as regards the manifold of the latter it determines nothing, but must await this determination by the Judgement, which subsumes the empirical intuition (if the object is a natural product) under the concept. We can however think an Understanding which, being, not like ours, discursive, but intuitive, proceeds from the synthetical-universal (the intuition of a whole as such) to the particular, i.e. from the whole to the parts. The contingency of the combination of the parts, in order that a definite form of the whole shall be possible, is not implied by such an Understanding and its representation of the whole. Our Understanding requires this because it must proceed from the parts as universally conceived grounds to different forms possible to be subsumed under them, as consequences. According to the constitution of our Understanding a real whole of nature is regarded only as the effect of the concurrent motive powers of the parts. Suppose then that we wish not to represent the possibility of the whole as dependent on that of the parts (after the manner of our discursive Understanding), but according to the standard of the intuitive (original) Understanding to represent the possibility of the parts (according to their constitution and combination) as dependent on that of the whole. In accordance with the above peculiarity of our Understanding it cannot happen that the whole shall contain the ground of the possibility of the connexion of the parts (which would be a contradiction in discursive cognition), but only that the representation of a whole may contain the ground of the possibility of its form and the connexion of the parts belonging to it. Now such a whole would be an effect (product) the representation of which is regarded as the cause of its possibility; but the product of a cause whose determining ground is merely the representation of its effect is called a purpose. Hence it is merely a consequence of the particular constitution of our Understanding, that it represents products of nature as possible, according to a different kind of causality from that of the natural laws of matter, namely, that of purposes and final causes. Hence also this principle has not to do with the possibility of such things themselves (even when considered as phenomena) according to the manner of their production, but merely with the judgement upon them which is possible to our Understanding. Here we see at once why it is that in natural science we are not long contented with an explanation of the products of nature by a causality according to purposes. For there we desire to judge of natural production merely in a manner conformable to our faculty of judging, i.e. to the reflective Judgement, and not in reference to things themselves on behalf of the determinant Judgement. It is here not at all requisite to prove that such an intellectus archetypus is possible, but only that we are led to the Idea of it,—which contains no contradiction,—in contrast to our discursive Understanding which has need of images (intellectus ectypus) and to the contingency of its constitution.

If we consider a material whole, according to its form, as a product of the parts with their powers and faculties of combining with one another (as well as of bringing in foreign materials), we represent to ourselves a mechanical mode of producing it. But in this way no concept emerges of a whole as purpose, whose internal possibility presupposes throughout the Idea of a whole on which depend the constitution and mode of action of the parts, as we must represent to ourselves an organised body. It does not follow indeed, as has been shown, that the mechanical production of such a body is impossible; for to say so would be to say that it would be impossible (contradictory) for any Understanding to represent to itself such a unity in the connexion of the manifold, without the Idea of the unity being at the same time its producing cause, i.e. without designed production. This, however, would follow in fact if we were justified in regarding material beings as things in themselves. For then the unity that constitutes the ground of the possibility of natural formations would be simply the unity of space. But space is no real ground of the products, but only their formal condition, although it has this similarity to the real ground which we seek that in it no part can be determined except in relation to the whole (the representation of which therefore lies at the ground of the possibility of the parts). But now it is at least possible to consider the material world as mere phenomenon, and to think as its substrate something like a thing in itself (which is not phenomenon), and to attach to this a corresponding intellectual intuition (even though it is not ours). Thus there would be, although incognisable by us, a supersensible real ground for nature, to which we ourselves belong. In this we consider according to mechanical laws what is necessary in nature regarded as an object of Sense; but we consider according to teleological laws the agreement and unity of its particular laws and its forms—which in regard to mechanism we must judge contingent—regarded as objects of Reason (in fact the whole of nature as a system). Thus we should judge nature according to two different kinds of principles without the mechanical way of explanation being shut out by the teleological, as if they contradicted one another.

From this we are enabled to see what otherwise, though we could easily surmise it, could with difficulty be maintained with certainty and proved, viz. that the principle of a mechanical derivation of purposive natural products is consistent with the teleological, but in no way enables us to dispense with it. In a thing that we must judge as a natural purpose (an organised being) we can no doubt try all the known and yet to be discovered laws of mechanical production, and even hope to make good progress therewith; but we can never get rid of the call for a quite different ground of production for the possibility of such a product, viz. causality by means of purposes. Absolutely no human Reason (in fact no finite Reason like ours in quality, however much it may surpass it in degree) can hope to understand the production of even a blade of grass by mere mechanical causes. As regards the possibility of such an object, the teleological connexion of causes and effects is quite indispensable for the Judgement, even for studying it by the clue of experience. For external objects as phenomena an adequate ground related to purposes cannot be met with; this, although it lies in nature, must only be sought in the supersensible substrate of nature, from all possible insight into which we are cut off. Hence it is absolutely impossible for us to produce from nature itself grounds of explanation for purposive combinations; and it is necessary by the constitution of the human cognitive faculties to seek the supreme ground of these purposive combinations in an original Understanding as the cause of the world.

§ 78. Of the union of the principle of the universal mechanism of matter with the teleological principle in the Technic of nature

It is infinitely important for Reason not to let slip the mechanism of nature in its products, and in their explanation not to pass it by, because without it no insight into the nature of things can be attained. Suppose it admitted that a supreme Architect immediately created the forms of nature as they have been from the beginning, or that He predetermined those which in the course of nature continually form themselves on the same model. Our knowledge of nature is not thus in the least furthered, because we cannot know the mode of action of that Being and the Ideas which are to contain the principles of the possibility of natural beings, and we cannot by them explain nature as from above downwards (a priori). And if, starting from the forms of the objects of experience, from below upwards (a posteriori), we wish to explain the purposiveness, which we believe is met with in experience, by appealing to a cause working in accordance with purposes, then is our explanation quite tautological and we are only mocking Reason with words. Indeed when we lose ourselves with this way of explanation in the transcendent, whither natural knowledge cannot follow, Reason is seduced into poetical extravagance, which it is its peculiar destination to avoid.

On the other hand, it is just as necessary a maxim of Reason not to pass by the principle of purposes in the products of nature. For, although it does not make their mode of origination any more comprehensible, yet it is a heuristic principle for investigating the particular laws of nature; supposing even that we wish to make no use of it for explaining nature itself,—in which we still always speak only of natural purposes, although it apparently exhibits a designed unity of purpose,—i.e. without seeking beyond nature the ground of the possibility of these particular laws. But since we must come in the end to this latter question, it is just as necessary to think for nature a particular kind of causality which does not present itself in it, as the mechanism of natural causes which does. To the receptivity of several forms, different from those of which matter is susceptible by mechanism, must be added a spontaneity of a cause (which therefore cannot be matter), without which no ground can be assigned for those forms. No doubt Reason, before it takes this step, must proceed with caution, and not try to explain teleologically every Technic of nature, i.e. every productive faculty of nature which displays in itself (as in regular bodies) purposiveness of figure to our mere apprehension; but must always regard such as so far mechanically possible. But on that account to wish entirely to exclude the teleological principle, and to follow simple mechanism only—in cases where, in the rational investigation of the possibility of natural forms through their causes, purposiveness shows itself quite undeniably as the reference to a different kind of causality—to do this must make Reason fantastic, and send it wandering among chimeras of unthinkable natural faculties; just as a mere teleological mode of explanation which takes no account of natural mechanism makes it visionary.

In the same natural thing both principles cannot be connected as fundamental propositions of explanation (deduction) of one by the other, i.e. they do not unite for the determinant Judgement as dogmatical and constitutive principles of insight into nature. If I choose, e.g. to regard a maggot as the product of the mere mechanism of nature (of the new formation that it produces of itself, when its elements are set free by corruption), I cannot derive the same product from the same matter as from a causality that acts according to purposes. Conversely, if I regard the same product as a natural purpose, I cannot count on any mechanical mode of its production and regard this as the constitutive principle of my judgement upon its possibility, and so unite both principles. One method of explanation excludes the other; even supposing that objectively both grounds of the possibility of such a product rested on a single ground, to which we did not pay attention. The principle which should render possible the compatibility of both in judging of nature must be placed in that which lies outside both (and consequently outside the possible empirical representation of nature), but yet contains their ground, i.e. in the supersensible; and each of the two methods of explanation must be referred thereto. Now of this we can have no concept but the indeterminate concept of a ground, which makes the judging of nature by empirical laws possible, but which we cannot determine more nearly by any predicate. Hence the union of both principles cannot rest upon a ground of explanation of the possibility of a product according to given laws, for the determinant Judgement, but only upon a ground of its exposition for the reflective Judgement.—To explain is to derive from a principle, which therefore we must clearly know and of which we can give an account. No doubt the principle of the mechanism of nature and that of its causality in one and the same natural product must coalesce in a single higher principle, which is their common source, because otherwise they could not subsist side by side in the observation of nature. But if this principle, objectively common to the two, which therefore warrants the association of the maxims of natural investigation depending on both, be such that, though it can be pointed to, it cannot be determinately known nor clearly put forward for use in cases which arise, then from such a principle we can draw no explanation, i.e. no clear and determinate derivation of the possibility of a natural product in accordance with those two heterogeneous principles. But now the principle common to the mechanical and teleological derivations is the supersensible, which we must place at the basis of nature, regarded as phenomenon. And of this, in a theoretical point of view, we cannot form the smallest positive determinate concept. It cannot, therefore, in any way be explained how, according to it as principle, nature (in its particular laws) constitutes for us one system, which can be cognised as possible either by the principle of physical development or by that of final causes. If it happens that objects of nature present themselves which cannot be thought by us, as regards their possibility, according to the principle of mechanism (which always has a claim on a natural being), without relying on teleological propositions, we can only make an hypothesis. Namely, we suppose that we may hopefully investigate natural laws with reference to both (according as the possibility of its product is cognisable by our Understanding by one or the other principle), without stumbling at the apparent contradiction which comes into view between the principles by which they are judged. For at least the possibility is assured that both may be united objectively in one principle, since they concern phenomena that presuppose a supersensible ground.

Mechanism, then, and the teleological (designed) Technic of nature, in respect of the same product and its possibility, may stand under a common supreme principle of nature in particular laws. But since this principle is transcendent we cannot, because of the limitation of our Understanding, unite both principles in the explanation of the same production of nature even if the inner possibility of this product is only intelligible [verständlich] through a causality according to purposes (as is the case with organised matter). We revert then to the above fundamental proposition of Teleology. According to the constitution of the human Understanding, no other than designedly-working causes can be assumed for the possibility of organised beings in nature; and the mere mechanism of nature cannot be adequate to the explanation of these its products. But we do not attempt to decide anything by this fundamental proposition as to the possibility of such things themselves.

This is only a maxim of the reflective, not of the determinant Judgement; consequently only subjectively valid for us, not objectively for the possibility of things themselves of this kind (in which both kinds of production may well cohere in one and the same ground). Further, without any concept,—besides the teleologically conceived method of production,—of a simultaneously presented mechanism of nature, no judgement can be passed on this kind of production as a natural product. Hence the above maxim leads to the necessity of an unification of both principles in judging of things as natural purposes in themselves, but does not lead us to substitute one for the other either altogether or in certain parts. For in the place of what is thought (at least by us) as possible only by design we cannot set mechanism, and in the place of what is cognised as mechanically necessary we cannot set contingency, which would need a purpose as its determining ground; but we can only subordinate the one (Mechanism) to the other (designed Technic), which may quite well be the case according to the transcendental principle of the purposiveness of nature.

For where purposes are thought as grounds of the possibility of certain things, we must assume also means, whose law of working requires for itself nothing presupposing a purpose,—a mechanical law—and yet can be a subordinate cause of designed effects. Thus—in the organic products of nature, and specially when prompted by their infinite number, we assume (at least as a permissible hypothesis) design in the combination of natural causes by particular laws as a universal principle of the reflective Judgement for the whole of nature (the world),—we can think a great and indeed universal combination of mechanical with teleological laws in the productions of nature, without interchanging the principles by which they are judged or putting one in the place of the other. For, in a teleological judgement, the matter, even if the form that it assumes be judged possible only by design, can also, conformably to the mechanical laws of its nature, be subordinated as a means to the represented purpose. But, since the ground of this compatibility lies in that which is neither one nor the other (neither mechanism nor purposive combination), but is the supersensible substrate of nature of which we know nothing, the two ways of representing the possibility of such Objects are not to be blended together by our (human) Reason. However, we cannot judge of their possibility otherwise than by judging them as ultimately resting on a supreme Understanding by the connexion of final causes; and thus the teleological method of explanation is not eliminated.

Now it is quite indeterminate, and for our Understanding always indeterminable, how much the mechanism of nature does as a means towards each final design in nature. However, on account of the above-mentioned intelligible principle of the possibility of a nature in general, it may be assumed that it is possible throughout according to the two kinds of universally accordant laws (the physical and those of final causes), although we cannot see into the way how this takes place. Hence we do not know how far the mechanical method of explanation which is possible for us may extend. So much only is certain that, so far as we can go in this direction, it must always be inadequate for things that we once recognise as natural purposes; and therefore we must, by the constitution of our Understanding, subordinate these grounds collectively to a teleological principle.

Hereon is based a privilege, and on account of the importance which the study of nature by the principle of mechanism has for the theoretical use of our Reason, also an appeal. We should explain all products and occurrences in nature, even the most purposive, by mechanism as far as is in our power (the limits of which we cannot specify in this kind of investigation). But at the same time we are not to lose sight of the fact that those things which we cannot even state for investigation except under the concept of a purpose of Reason, must, in conformity with the essential constitution of our Reason, mechanical causes notwithstanding, be subordinated by us finally to causality in accordance with purposes.

METHODOLOGY OF THE TELEOLOGICAL JUDGEMENT.119

§ 79. Whether teleology must be treated as if it belonged to the doctrine of nature

Every science must have its definite position in the encyclopaedia of all the sciences. If it is a philosophical science its position must be either in the theoretical or practical part. If again it has its place in the former of these, it must be either in the doctrine of nature, so far as it concerns that which can be an object of experience (in the doctrine of bodies, the doctrine of the soul, or the universal science of the world), or in the doctrine of God (the original ground of the world as the complex of all objects of experience).

Now the question is, what place is due to Teleology? Does it belong to Natural Science (properly so called) or to Theology? One of the two it must be; for no science belongs to the transition from one to the other, because this transition only marks the articulation or organisation of the system, and not a place in it.

That it does not belong to Theology as a part thereof, although it may be made of the most important use therein, is self-evident. For it has as its objects, natural productions, and their cause, and although it refers at the same time to the latter as to a ground lying outside of and beyond nature (a Divine Author), yet it does not do this for the determinant but only for the reflective Judgement in the consideration of nature (in order to guide our judgement on things in the world by means of such an Idea as a regulative principle, in conformity with the human Understanding).

But it appears to belong just as little to Natural Science, which needs determinant and not merely reflective principles in order to supply objective grounds for natural effects. In fact, nothing is gained for the theory of nature or the mechanical explanation of its phenomena by means of its effective causes, by considering them as connected according to the relation of purposes. The exhibition of the purposes of nature in its products, so far as they constitute a system according to teleological concepts, properly belongs only to a description of nature which is drawn up in accordance with a particular guiding thread. Here Reason, no doubt, accomplishes a noble work, instructive and practically purposive in many points of view; but it gives no information as to the origin and the inner possibility of these forms, which is the special business of theoretical Natural Science. Teleology, therefore, as science, belongs to no Doctrine, but only to Criticism; and to the criticism of a special cognitive faculty, viz. Judgement. But so far as it contains principles a priori, it can and must furnish the method by which nature must be judged according to the principle of final causes. Hence its Methodology has at least negative influence upon the procedure in theoretical Natural Science, and also upon the relation which this can have in Metaphysic to Theology as its propaedeutic.

§ 80. Of the necessary subordination of the mechanical to the teleological principle in the explanation of a thing as a natural purpose

The privilege of aiming at a merely mechanical method of explanation of all natural products is in itself quite unlimited; but the faculty of attaining thereto is by the constitution of our Understanding, so far as it has to do with things as natural purposes, not only very much limited but also clearly bounded. For, according to a principle of the Judgement, by this process alone nothing can be accomplished towards an explanation of these things; and consequently the judgement upon such products must always be at the same time subordinated by us to a teleological principle.

It is therefore rational, even meritorious, to pursue natural mechanism, in respect of the explanation of natural products, so far as can be done with probability; and if we give up the attempt it is not because it is impossible in itself to meet in this path with the purposiveness of nature, but only because it is impossible for us as men. For there would be required for that an intuition other than sensuous, and a determinate knowledge of the intelligible substrate of nature from which a ground could be assigned for the mechanism of phenomena according to particular laws, which quite surpasses our faculties.

Hence if the naturalist would not waste his labour he must in judging of things, the concept of any of which is indubitably established as a natural purpose (organised beings), always lay down as basis an original organisation, which uses that very mechanism in order to produce fresh organised forms or to develop the existing ones into new shapes (which, however, always result from that purpose and conformably to it).

It is praiseworthy by the aid of comparative anatomy to go through the great creation of organised natures, in order to see whether there may not be in it something similar to a system and also in accordance with the principle of production. For otherwise we should have to be content with the mere principle of judgement (which gives no insight into their production) and, discouraged, to give up all claim to natural insight in this field. The agreement of so many genera of animals in a certain common schema, which appears to be fundamental not only in the structure of their bones but also in the disposition of their remaining parts,—so that with an admirable simplicity of original outline, a great variety of species has been produced by the shortening of one member and the lengthening of another, the involution of this part and the evolution of that,—allows a ray of hope, however faint, to penetrate into our minds, that here something may be accomplished by the aid of the principle of the mechanism of nature (without which there can be no natural science in general). This analogy of forms, which with all their differences seem to have been produced according to a common original type, strengthens our suspicions of an actual relationship between them in their production from a common parent, through the gradual approximation of one animal-genus to another—from those in which the principle of purposes seems to be best authenticated, i.e. from man, down to the polype, and again from this down to mosses and lichens, and finally to the lowest stage of nature noticeable by us, viz. to crude matter. And so the whole Technic of nature, which is so incomprehensible to us in organised beings that we believe ourselves compelled to think a different principle for it, seems to be derived from matter and its powers according to mechanical laws (like those by which it works in the formation of crystals).

Here it is permissible for the archaeologist of nature to derive from the surviving traces of its oldest revolutions, according to all its mechanism known or supposed by him, that great family of creatures (for so we must represent them if the said thoroughgoing relationship is to have any ground). He can suppose the bosom of mother earth, as she passed out of her chaotic state (like a great animal), to have given birth in the beginning to creatures of less purposive form, that these again gave birth to others which formed themselves with greater adaptation to their place of birth and their relations to each other; until this womb becoming torpid and ossified, limited its births to definite species not further modifiable, and the manifoldness remained as it was at the end of the operation of that fruitful formative power.—Only he must still in the end ascribe to this universal mother an organisation purposive in respect of all these creatures; otherwise it would not be possible to think the possibility of the purposive form of the products of the animal and vegetable kingdoms.120 He has then only pushed further back the ground of explanation and cannot pretend to have made the development of those two kingdoms independent of the condition of final causes.

Even as concerns the variation to which certain individuals of organised genera are accidentally subjected, if we find that the character so changed is hereditary and is taken up into the generative power, then we cannot pertinently judge the variation to be anything else than an occasional development of purposive capacities originally present in the species with a view to the preservation of the race. For in the complete inner purposiveness of an organised being, the generation of its like is closely bound up with the condition of taking nothing up into the generative power which does not belong, in such a system of purposes, to one of its undeveloped original capacities. Indeed, if we depart from this principle, we cannot know with certainty whether several parts of the form which is now apparent in a species have not a contingent and unpurposive origin; and the principle of Teleology, to judge nothing in an organised being as unpurposive which maintains it in its propagation, would be very unreliable in its application and would be valid solely for the original stock (of which we have no further knowledge).

Hume121 takes exception to those who find it requisite to assume for all such natural purposes a teleological principle of judgement, i.e. an architectonic Understanding. He says that it may fairly be asked: how is such an Understanding possible? How can the manifold faculties and properties that constitute the possibility of an Understanding, which has at the same time executive force, be found so purposively together in one Being? But this objection is without weight. For the whole difficulty which surrounds the question concerning the first production of a thing containing in itself purposes and only comprehensible by means of them, rests on the further question as to the unity of the ground of the combination in this product of the various elements [des Mannichfaltigen] which are external to one another. For if this ground be placed in the Understanding of a producing cause as simple substance, the question, so far as it is teleological, is sufficiently answered; but if the cause be sought merely in matter as an aggregate of many substances external to one another, the unity of the principle is quite wanting for the internally purposive form of its formation, and the autocracy of matter in productions which can only be conceived by our Understanding as purposes is a word without meaning.

Hence it comes to pass that those who seek a supreme ground of possibility for the objectively-purposive forms of matter, without attributing to it Understanding, either make the world-whole into a single all-embracing substance (Pantheism), or (which is only a more determinate explanation of the former) into a complex of many determinations inhering in a single simple substance (Spinozism); merely in order to satisfy that condition of all purposiveness—the unity of ground. Thus they do justice indeed to one condition of the problem, viz. the unity in the purposive combination, by means of the mere ontological concept of a simple substance; but they adduce nothing for the other condition, viz. the relation of this substance to its result as purpose, through which relation that ontological ground is to be more closely determined in respect of the question at issue. Hence they answer the whole question in no way. It remains absolutely unanswerable (for our Reason) if we do not represent that original ground of things, as simple substance; its property which has reference to the specific constitution of the forms of nature grounded thereon, viz. its purposive unity, as the property of an intelligent substance; and the relation of these forms to this intelligence (on account of the contingency which we ascribe to everything that we think possible only as a purpose) as that of causality.

§ 81. Of the association of mechanism with the teleological principle in the explanation of a natural purpose as a natural product

According to the preceding paragraphs the mechanism of nature alone does not enable us to think the possibility of an organised being; but (at least according to the constitution of our cognitive faculty) it must be originally subordinated to a cause working designedly. But, just as little is the mere teleological ground of such a being sufficient for considering it and judging it as a product of nature, if the mechanism of the latter be not associated with the former, like the instrument of a cause working designedly, to whose purposes nature is subordinated in its mechanical laws. The possibility of such a unification of two quite different kinds of causality,—of nature in its universal conformity to law with an Idea which limits it to a particular form, for which it contains no ground in itself—is not comprehended by our Reason. It lies in the supersensible substrate of nature, of which we can determine nothing positively, except that it is the being in itself of which we merely know the phenomenon. But the principle, “all that we assume as belonging to this nature (phenomenon) and as its product, must be thought as connected therewith according to mechanical laws,” has none the less force, because without this kind of causality organised beings (as purposes of nature) would not be natural products.

Now if the teleological principle of the production of these beings be assumed (as is inevitable), we can place at the basis of the cause of their internally purposive form either Occasionalism or Pre-established Harmony. According to the former the Supreme Cause of the world would, conformably to its Idea, furnish immediately the organic formation on the occasion of every union of intermingling materials. According to the latter it would, in the original products of its wisdom, only have supplied the capacity by means of which an organic being produces another of like kind, and the species perpetually maintains itself; whilst the loss of individuals is continually replaced by that nature which at the same time works towards their destruction. If we assume the Occasionalism of the production of organised beings, all nature is quite lost, and with it all employment of Reason in judging of the possibility of such products; hence we may suppose that no one will adopt this system, who has anything to do with philosophy.

[The theory of] Pre-established Harmony may proceed in two different ways. It regards every organised being as generated by one of like kind, either as an educt or a product. The system which regards generations as mere educts is called the theory of individual preformation or the theory of evolution: that which regards them as products is entitled the system of epigenesis. This latter may also be entitled the system of generic preformation, because the productive faculty of the generator and consequently the specific form would be virtually performed according to the inner purposive capacities which are part of its stock. In correspondence with this the opposite theory of individual preformations would be better entitled the theory of involution.

The advocates of the theory of evolution, who remove every individual from the formative power of nature, in order to make it come immediately from the hand of the Creator, would, however, not venture to regard this as happening according to the hypothesis of Occasionalism. For according to this the copulation is a mere formality, à propos of which a supreme intelligent Cause of the world has concluded to form a fruit immediately by his hand, and only to leave to the mother its development and nourishment. They declare themselves for preformation; as if it were not all the same, whether a supernatural origin is assigned to these forms in the beginning or in the course of the world. On the contrary, a great number of supernatural arrangements would be spared by occasional creation, which would be requisite, in order that the embryo formed in the beginning of the world might not be injured throughout the long period of its development by the destructive powers of nature, and might keep itself unharmed; and there would also be requisite an incalculably greater number of such preformed beings than would ever be developed, and with them many creations would be made without need and without purpose. They would, however, be willing to leave at least something to nature, so as not to fall into a complete Hyperphysic which can dispense with all natural explanations. It is true, they hold so fast by their Hyperphysic that they find even in abortions (which it is quite impossible to take for purposes of nature) an admirable purposiveness; though it be only directed to the fact that an anatomist would take exception to it as a purposeless purposiveness, and would feel a disheartened wonder thereat. But the production of hybrids could absolutely not be accommodated with the system of preformation; and to the seeds of the male creature, to which they had attributed nothing but the mechanical property of serving as the first means of nourishment for the embryo, they must attribute in addition a purposive formative power, which in the case of the product of two creatures of the same genus they would concede to neither parent.

On the other hand, even if we do not recognise the great superiority which the theory of Epigenesis has over the former as regards the empirical grounds of its proof, still prior to proof Reason views this way of explanation with peculiar favour. For in respect of the things which we can only represent as possible originally according to the causality of purposes, at least as concerns their propagation, this theory regards nature as self-producing, not merely as self-evolving: and so with the least expenditure of the supernatural leaves to nature all that follows after the first beginning (though without determining anything about this first beginning by which Physic generally is thwarted, however it may essay its explanation by a chain of causes).

As regards this theory of Epigenesis, no one has contributed more either to its proof or to the establishment of the legitimate principles of its application,—partly by the limitation of a too presumptuous employment of it,—than Herr Hofr. Blumenbach.122 In all physical explanations of these formations he starts from organised matter. That crude matter should have originally formed itself according to mechanical laws, that life should have sprung from the nature of what is lifeless, that matter should have been able to dispose itself into the form of a self-maintaining purposiveness—this he rightly declares to be contradictory to Reason. But at the same time he leaves to natural mechanism under this to us indispensable principle of an original organisation, an undeterminable but yet unmistakeable element, in reference to which the faculty of matter in an organised body is called by him a formative impulse (in contrast to, and yet standing under the higher guidance and direction of, that merely mechanical formative power universally resident in matter).

§ 82. Of the teleological system in the external relations of organised beings

By external purposiveness I mean that by which one thing of nature serves another as means to a purpose. Now things which have no internal purposiveness and which presuppose none for their possibility, e.g. earth, air, water, etc., may at the same time be very purposive externally, i.e. in relation to other beings. But these latter must be organised beings, i.e. natural purposes, for otherwise the former could not be judged as means to them. Thus water, air, and earth cannot be regarded as means to the raising of mountains, because mountains contain nothing in themselves that requires a ground of their possibility according to purposes, in reference to which therefore their cause can never be represented under the predicate of a means (as useful therefor).

External purposiveness is a quite different concept from that of internal purposiveness, which is bound up with the possibility of an object irrespective of its actuality being itself a purpose. We can ask about an organised being the question: What is it for? But we cannot easily ask this about things in which we recognise merely the working of nature’s mechanism. For in the former, as regards their internal possibility, we represent a causality according to purposes, a creative Understanding, and we refer this active faculty to its determining ground, viz. design. There is only one external purposiveness which is connected with the internal purposiveness of organisation, and yet serves in the external relation of a means to a purpose, without the question necessarily arising, as to what end this being so organised must have existed for. This is the organisation of both sexes in their mutual relation for the propagation of their kind; since here we can always ask, as in the case of an individual, why must such a pair exist? The answer is: This pair first constitutes an organising whole, though not an organised whole in a single body.

If we now ask, wherefore anything is, the answer is either: Its presence and its production have no reference at all to a cause working according to design, and so we always refer its origin to the mechanism of nature, or: There is somewhere a designed ground of its presence (as a contingent natural being). This thought we can hardly separate from the concept of an organised thing; for, since we must place at the basis of its internal possibility a causality of final causes and an Idea lying at the ground of this, we cannot think the existence of this product except as a purpose. For the represented effect, the representation of which is at the same time the determining ground of the intelligent cause working towards its production, is called a purpose. In this case therefore we can either say: The purpose of the existence of such a natural being is in itself; i.e. it is not merely a purpose but a final purpose, or: This is external to it in another natural being, i.e. it exists purposively not as a final purpose, but necessarily as a means.

But if we go through the whole of nature we find in it, as nature, no being which could make claim to the eminence of being the final purpose of creation; and we can even prove a priori that what might be for nature an ultimate purpose, according to all the thinkable determinations and properties wherewith one could endow it, could yet as a natural thing never be a final purpose.

If we consider the vegetable kingdom we might at first sight, on account of the immeasurable fertility with which it spreads itself almost on every soil, be led to take it for a mere product of that mechanism which nature displays in the formations of the mineral kingdom. But a more intimate knowledge of its indescribably wise organisation does not permit us to hold to this thought, but prompts the question: What are these things created for? If it is answered: For the animal kingdom, which is thereby nourished and has thus been able to spread over the earth in genera so various, then the further question comes: What are these plant-devouring animals for? The answer would be something like this: For beasts of prey, which can only be nourished by that which has life. Finally we have the question: What are these last, as well as the first-mentioned natural kingdoms, good for? For man, in reference to the manifold use which his Understanding teaches him to make of all these creatures. He is the ultimate purpose of creation here on earth, because he is the only being upon it who can form a concept of purposes, and who can by his Reason make out of an aggregate of purposively formed things a system of purposes.

We might also with the chevalier Linnaeus123 go the apparently opposite way and say: The herbivorous animals are there to moderate the luxurious growth of the vegetable kingdom, by which many of its species are choked. The carnivora are to set bounds to the voracity of the herbivora. Finally man, by his pursuit of these and his diminution of their numbers, preserves a certain equilibrium between the producing and the destructive powers of nature. And so man, although in a certain reference he might be esteemed a purpose, yet in another has only the rank of a means.

If an objective purposiveness in the variety of the genera of creatures and their external relations to one another, as purposively constructed beings, be made a principle, then it is conformable to Reason to conceive in these relations a certain organisation and a system of all natural kingdoms according to final causes. Only here experience seems flatly to contradict the maxims of Reason, especially as concerns an ultimate purpose of nature, which is indispensable for the possibility of such a system and which we can put nowhere else but in man. For regarding him as one of the many animal genera, nature has not in the least excepted him from its destructive or its productive powers, but has subjected everything to a mechanism thereof without any purpose.

The first thing that must be designedly prepared in an arrangement for a purposive complex of natural beings on the earth would be their place of habitation, the soil and the element on and in which they are to thrive. But a more exact knowledge of the constitution of this basis of all organic production indicates no other causes than those working quite undesignedly, causes which rather destroy than favour production, order, and purposes. Land and sea not only contain in themselves memorials of ancient mighty desolations which have confounded them and all creatures that are in them; but their whole structure, the strata of the one and the boundaries of the other, have quite the appearance of being the product of the wild and violent forces of a nature working in a state of chaos. Although the figure, the structure, and the slope of the land might seem to be purposively ordered for the reception of water from the air, for the welling up of streams between strata of different kinds (for many kinds of products), and for the course of rivers—yet a closer investigation shows that they are merely the effects of volcanic eruptions or of inundations of the ocean, as regards not only the first production of this figure, but, above all, its subsequent transformation, as well as the disappearance of its first organic productions.124 Now if the place of habitation of all these creatures, the soil (of the land) or the bosom (of the sea), indicates nothing but a quite undesigned mechanism of its production, how and with what right can we demand and maintain a different origin for these latter products? The closest examination, indeed (in Camper’s125 judgement), of the remains of the aforesaid devastations of nature seems to show that man was not comprehended in these revolutions; but yet he is so dependent on the remaining creatures that, if a universally directing mechanism of nature be admitted in the case of the others, he must also be regarded as comprehended under it; even though his Understanding (for the most part at least) has been able to deliver him from these devastations.

But this argument seems to prove more than was intended by it. It seems to prove not merely that man cannot be the ultimate purpose of nature, and that on the same grounds the aggregate of the organised things of nature on the earth cannot be a system of purposes; but also that the natural products formerly held to be natural purposes have no other origin than the mechanism of nature.

But in the solution given above of the Antinomy of the principles of the mechanical and teleological methods of production of organic beings of nature, we have seen that they are merely principles of the reflective Judgement in respect of nature as it produces forms in accordance with particular laws (for the systematic connexion of which we have no key). They do not determine the origin of these beings in themselves; but only say that we, by the constitution of our Understanding and our Reason, cannot conceive it in this kind of being except according to final causes. The greatest possible effort, even audacity, in the attempt to explain them mechanically is not only permitted, but we are invited to it by Reason; notwithstanding that we know from the subjective grounds of the particular species and limitations of our Understanding (not e.g. because the mechanism of production would contradict in itself an origin according to purposes) that we can never attain thereto. Finally, the compatibility of both ways of representing the possibility of nature may lie in the supersensible principle of nature (external to us, as well as in us); whilst the method of representation according to final causes may be only a subjective condition of the use of our Reason, when it not merely wishes to form a judgement upon objects as phenomena, but desires to refer these phenomena together with their principles to their supersensible substrate, in order to find certain laws of their unity possible, which it cannot represent to itself except through purposes (of which the Reason also has such as are supersensible).

§ 83. Of the ultimate purpose of nature as a teleological system

We have shown in the preceding that, though not for the determinant but for the reflective Judgement, we have sufficient cause for judging man to be, not merely like all organised beings a natural purpose, but also the ultimate purpose of nature here on earth; in reference to whom all other natural things constitute a system of purposes according to fundamental propositions of Reason. If now that must be found in man himself, which is to be furthered as a purpose by means of his connexion with nature, this purpose must either be of a kind that can be satisfied by nature in its beneficence; or it is the aptitude and skill for all kinds of purposes for which nature (external and internal) can be used by him. The first purpose of nature would be man’s happiness, the second his culture.

The concept of happiness is not one that man derives by abstraction from his instincts and so deduces from his animal nature; but it is a mere Idea of a state, that he wishes to make adequate to the Idea under merely empirical conditions (which is impossible). This Idea he projects in such different ways on account of the complication of his Understanding with Imagination and Sense, and changes so often, that nature, even if it were entirely subjected to his elective will, could receive absolutely no determinate, universal and fixed law, so as to harmonise with this vacillating concept and thus with the purpose which each man arbitrarily sets before himself. And even if we reduce this to the true natural wants as to which our race is thoroughly agreed, or on the other hand, raise ever so high man’s skill to accomplish his imagined purposes; yet, even thus, what man understands by happiness, and what is in fact his proper, ultimate, natural purpose (not purpose of freedom), would never be attained by him. For it is not his nature to rest and be contented with the possession and enjoyment of anything whatever. On the other side, too, there is something wanting. Nature has not taken him for her special darling and favoured him with benefit above all animals. Rather, in her destructive operations,—plague, hunger, perils of waters, frost, assaults of other animals great and small, etc.,—in these things has she spared him as little as any other animal. Further, the inconsistency of his own natural dispositions drives him into self-devised torments, and also reduces others of his own race to misery, by the oppression of lordship, the barbarism of war, and so forth; he, himself, as far as in him lies, works for the destruction of his own race; so that even with the most beneficent external nature, its purpose, if it were directed to the happiness of our species, would not be attained in an earthly system, because our nature is not susceptible of it. Man is then always only a link in the chain of natural purposes; a principle certainly in respect of many purposes, for which nature seems to have destined him in her disposition, and towards which he sets himself, but also a means for the maintenance of purposiveness in the mechanism of the remaining links. As the only being on earth which has an Understanding and, consequently, a faculty of setting arbitrary purposes before itself, he is certainly entitled to be the lord of nature; and if it be regarded as a teleological system he is, by his destination, the ultimate purpose of nature. But this is subject to the condition of his having an Understanding and the Will to give to it and to himself such a reference to purposes, as can be self-sufficient independently of nature, and, consequently, can be a final purpose; which, however, must not be sought in nature itself.

But in order to find out where in man we have to place that ultimate purpose of nature, we must seek out what nature can supply to prepare him for what he must do himself in order to be a final purpose, and we must separate it from all those purposes whose possibility depends upon things that one can expect only from nature. Of the latter kind is earthly happiness, by which is understood the complex of all man’s purposes possible through nature, whether external nature or man’s nature; i.e. the matter of all his earthly purposes, which, if he makes it his whole purpose, renders him incapable of positing his own existence as a final purpose, and being in harmony therewith. There remains therefore of all his purposes in nature only the formal subjective condition; viz. the aptitude of setting purposes in general before himself, and (independent of nature in his purposive determination) of using nature, conformably to the maxims of his free purposes in general, as a means. This nature can do in regard to the final purpose that lies outside it, and it therefore may be regarded as its ultimate purpose. The production of the aptitude of a rational being for arbitrary purposes in general (consequently in his freedom) is culture. Therefore, culture alone can be the ultimate purpose which we have cause for ascribing to nature in respect to the human race (not man’s earthly happiness or the fact that he is the chief instrument of instituting order and harmony in irrational nature external to himself).

But all culture is not adequate to this ultimate purpose of nature. The culture of skill is indeed the chief subjective condition of aptitude for furthering one’s purposes in general; but it is not adequate to furthering the will126 in the determination and choice of purposes, which yet essentially belongs to the whole extent of an aptitude for purposes. The latter condition of aptitude, which we might call the culture of training (discipline), is negative, and consists in the freeing of the will from the despotism of desires. By these, tied as we are to certain natural things, we are rendered incapable even of choosing, while we allow those impulses to serve as fetters, which Nature has given us as guiding threads that we should not neglect or violate the destination of our animal nature—we being all the time free enough to strain or relax, to extend or diminish them, according as the purposes of Reason require.

Skill cannot be developed in the human race except by means of inequality among men; for the great majority provide the necessities of life, as it were, mechanically, without requiring any art in particular, for the convenience and leisure of others who work at the less necessary elements of culture, science and art. In an oppressed condition they have hard work and little enjoyment, although much of the culture of the higher classes gradually spreads to them. Yet with the progress of this culture (the height of which is called luxury, reached when the propensity to what can be done without begins to be injurious to what is indispensable), their calamities increase equally in two directions, on the one hand through violence from without, on the other hand through internal discontent; but still this splendid misery is bound up with the development of the natural capacities of the human race, and the purpose of nature itself, although not our purpose, is thus attained. The formal condition under which nature can alone attain this its final design, is that arrangement of men’s relations to one another, by which lawful authority in a whole, which we call a civil community, is opposed to the abuse of their conflicting freedoms; only in this can the greatest development of natural capacities take place. For this also there would be requisite,—if men were clever enough to find it out and wise enough to submit themselves voluntarily to its constraint,—a cosmopolitan whole, i.e. a system of all states that are in danger of acting injuriously upon each other.127 Failing this, and with the obstacles which ambition, lust of dominion, and avarice, especially in those who have the authority in their hands, oppose even to the possibility of such a scheme, there is, inevitably, war (by which sometimes states subdivide and resolve themselves into smaller states, sometimes a state annexes other smaller states and strives to form a greater whole). Though war is an undesigned enterprise of men (stirred up by their unbridled passions), yet is it [perhaps]128 a deep-hidden and designed enterprise of supreme wisdom for preparing, if not for establishing, conformity to law amid the freedom of states, and with this a unity of a morally grounded system of those states. In spite of the dreadful afflictions with which it visits the human race, and the perhaps greater afflictions with which the constant preparation for it in time of peace oppresses them, yet is it (although the hope for a restful state of popular happiness is ever further off) a motive for developing all talents serviceable for culture, to the highest possible pitch.129

As concerns the discipline of the inclinations,—for which our natural capacity in regard of our destination as an animal race is quite purposive, but which render the development of humanity very difficult,—there is manifest in respect of this second requirement for culture a purposive striving of nature to a cultivation which makes us receptive of higher purposes than nature itself can supply. We cannot strive against the preponderance of evil, which is poured out upon us by the refinement of taste pushed to idealisation, and even by the luxury of science as affording food for pride, through the insatiable number of inclinations thus aroused. But yet we cannot mistake the purpose of nature—ever aiming to win us away from the rudeness and violence of those inclinations (inclinations to enjoyment) which belong rather to our animality, and for the most part are opposed to the cultivation of our higher destiny, and to make way for the development of our humanity. The beautiful arts and the sciences which, by their universally-communicable pleasure, and by the polish and refinement of society, make man more civilised, if not morally better, win us in large measure from the tyranny of sense-propensions, and thus prepare men for a lordship, in which Reason alone shall have authority; whilst the evils with which we are visited, partly by nature, partly by the intolerant selfishness of men, summon, strengthen, and harden the powers of the soul not to submit to them, and so make us feel an aptitude for higher purposes, which lies hidden in us.130

§ 84. Of the final purpose of the existence of a world, i.e. of creation itself

A final purpose is that purpose which needs no other as condition of its possibility.

If the mere mechanism of nature be assumed as the ground of explanation of its purposiveness, we cannot ask: what are things in the world there for? For according to such an idealistic system it is only the physical possibility of things (to think which as purposes would be mere subtlety without any Object) that is under discussion; whether we refer this form of things to chance or to blind necessity, in either case the question would be vain. If, however, we assume the purposive combination in the world to be real and to be [brought about] by a particular kind of causality, viz. that of a designedly-working cause, we cannot stop at the question: why have things of the world (organised beings) this or that form? why are they placed by nature in this or that relation to one another? But once an Understanding is thought that must be regarded as the cause of the possibility of such forms as are actually found in things, it must be also asked on objective grounds: Who could have determined this productive Understanding to an operation of this kind? This being is then the final purpose in reference to which such things are there.

I have said above that the final purpose is not a purpose which nature would be competent to bring about and to produce in conformity with its Idea, because it is unconditioned. For there is nothing in nature (regarded as a sensible being) for which the determining ground present in itself would not be always conditioned; and this holds not merely of external (material) nature, but also of internal (thinking) nature—it being of course understood that I only am considering that in myself which is nature. But a thing that is to exist necessarily, on account of its objective constitution, as the final purpose of an intelligent cause, must be of the kind that in the order of purposes it is dependent on no further condition than merely its Idea.

Now we have in the world only one kind of beings whose causality is teleological, i.e. is directed to purposes and is at the same time so constituted that the law according to which they have to determine purposes for themselves is represented as unconditioned and independent of natural conditions, and yet as in itself necessary. The being of this kind is man, but man considered as noumenon; the only natural being in which we can recognise, on the side of its peculiar constitution, a supersensible faculty (freedom) and also the law of causality, together with its Object, which this faculty may propose to itself as highest purpose (the highest good in the world).

Now of man (and so of every rational creature in the World) as a moral being it can no longer be asked: why (quem in finem) he exists? His existence involves the highest purpose to which, as far as is in his power, he can subject the whole of nature; contrary to which at least he cannot regard himself as subject to any influence of nature.—If now things of the world, as beings dependent in their existence, need a supreme cause acting according to purposes, man is the final purpose of creation; since without him the chain of mutually subordinated purposes would not be complete as regards its ground. Only in man, and only in him as subject of morality, do we meet with unconditioned legislation in respect of purposes, which therefore alone renders him capable of being a final purpose, to which the whole of nature is teleologically subordinated.131

§ 85. Of Physico-theology

Physico-theology is the endeavour of Reason to infer the Supreme Cause of nature and its properties from the purposes of nature (which can only be empirically known). Moral theology (ethico-theology) would be the endeavour to infer that Cause and its properties from the moral purpose of rational beings in nature (which can be known a priori).

The former naturally precedes the latter. For if we wish to infer a World Cause teleologically from the things in the world, purposes of nature must first be given, for which we afterwards have to seek a final purpose, and for this the principle of the causality of this Supreme Cause.

Many investigations of nature can and must be conducted according to the teleological principle, without our having cause to inquire into the ground of the possibility of purposive working with which we meet in various products of nature. But if we wish to have a concept of this we have absolutely no further insight into it than the maxim of the reflective Judgement affords: viz. if only a single organic product of nature were given to us, by the constitution of our cognitive faculty we could think no other ground for it than that of a cause of nature itself (whether the whole of nature or only this bit of it) which contains the causality for it through Understanding. This principle of judging, though it does not bring us any further in the explanation of natural things and their origin, yet discloses to us an outlook over nature, by which perhaps we may be able to determine more closely the concept, otherwise so unfruitful, of an Original Being.

Now I say that Physico-theology, however far it may be pursued, can disclose to us nothing of a final purpose of creation; for it does not even extend to the question as to this. It can, it is true, justify the concept of an intelligent World Cause, as a subjective concept (only available for the constitution of our cognitive faculty) of the possibility of things that we can make intelligible to ourselves according to purposes; but it cannot determine this concept further, either in a theoretical or a practical point of view. Its endeavour does not come up to its design of being the basis of a Theology, but it always remains only a physical Teleology; because the purposive reference therein is and must be always considered only as conditioned in nature, and it consequently cannot inquire into the purpose for which nature itself exists (for which the ground must be sought outside nature),—notwithstanding that it is upon the determinate Idea of this that the determinate concept of that Supreme Intelligent World Cause, and the consequent possibility of a Theology, depend.

What the things in the world are mutually useful for; what good the manifold in a thing does for the thing; how we have ground to assume that nothing in the world is in vain, but that everything in nature is good for something,—the condition being granted that certain things are to exist (as purposes), whence our Reason has in its power for the Judgement no other principle of the possibility of the Object, which it inevitably judges teleologically, than that of subordinating the mechanism of nature to the Architectonic of an intelligent Author of the world—all this the teleological consideration of the world supplies us with excellently and to our extreme admiration. But because the data, and so the principles, for determining that concept of an intelligent World Cause (as highest artist) are merely empirical, they do not enable us to infer any of its properties beyond those which experience reveals in its effects. Now experience, since it can never embrace collective nature as a system, must often (apparently) happen upon this concept (and by mutually conflicting grounds of proof); but it can never, even if we had the power of surveying empirically the whole system as far as it concerns mere nature, raise us above nature to the purpose of its existence, and so to the determinate concept of that supreme Intelligence.

If we lessen the problem with the solution of which Physico-theology has to do, its solution appears easy. If we reduce the concept of a Deity to that of an intelligent being thought by us, of which there may be one or more, which possesses many and very great properties, but not all the properties which are requisite for the foundation of a nature in harmony with the greatest possible purpose; or if we do not scruple in a theory to supply by arbitrary additions what is deficient in the grounds of proof, and so, where we have only ground for assuming much perfection (and what is “much” for us?), consider ourselves entitled to presuppose all possible perfection; thus indeed physical Teleology may make weighty claims to the distinction of being the basis of a Theology. But if we are desired to point out what impels and moreover authorises us to add these supplements, then we shall seek in vain for a ground of justification in the principles of the theoretical use of Reason, which is ever desirous in the explanation of an Object of experience to ascribe to it no more properties than those for which empirical data of possibility are to be found. On closer examination we should see that properly speaking an Idea of a Supreme Being, which rests on a quite different use of Reason (the practical use), lies in us fundamentally a priori, impelling us to supplement, by the concept of a Deity, the defective representation, supplied by a physical Teleology, of the original ground of the purposes in nature; and we should not falsely imagine that we had worked out this Idea, and with it a Theology by means of the theoretical use of Reason in the physical cognition of the world—much less that we had proved its reality.

One cannot blame the ancients much, if they thought of their gods as differing much from each other both as regards their faculties and as regards their designs and volitions, but yet thought of all of them, the Supreme One not excepted, as always limited after human fashion. For if they considered the arrangement and the course of things in nature, they certainly found ground enough for assuming something more than mechanism as its cause, and for conjecturing behind the machinery of this world designs of certain higher causes, which they could not think otherwise than superhuman. But because they met with good and evil, the purposive and the unpurposive, mingled together (at least as far as our insight goes), and could not permit themselves to assume nevertheless that wise and benevolent purposes of which they saw no proof lay hidden at bottom, on behalf of the arbitrary Idea of a supremely perfect original Author, their judgement upon the supreme World Cause could hardly have been other than it was, so long as they proceeded consistently according to maxims of the mere theoretical use of Reason. Others, who wished to be theologians as well as physicists, thought to find contentment for the Reason by providing for the absolute unity of the principle of natural things which Reason demands, the Idea of a Being of which as sole Substance the things would be all only inherent determinations. This Substance would not be Cause of the World by means of intelligence, but in it all the intelligences of the beings in the world would be comprised. This Being consequently would produce nothing according to purposes; but in it all things, on account of the unity of the subject of which they are mere determinations, must necessarily relate themselves purposively to one another, though without purpose and design. Thus they introduced the Idealism of final causes, by changing the unity (so difficult to explain) of a number of purposively combined substances, from being the unity of causal dependence on one Substance to be the unity of inherence in one. This system—which in the sequel, considered on the side of the inherent world beings, becomes Pantheism, and (later) on the side of the Subject subsisting by itself as Original Being, becomes Spinozism,—does not so much resolve as explain away into nothing the question of the first ground of the purposiveness of nature; because this latter concept, bereft of all reality, must be taken for a mere misinterpretation of a universal ontological concept of a thing in general.

Hence the concept of a Deity, which would be adequate for our teleological judging of nature, can never be derived from mere theoretical principles of the use of Reason (on which Physico-theology alone is based). For as one alternative we may explain all Teleology as a mere deception of the Judgement in its judging of the causal combination of things, and fly to the sole principle of a mere mechanism of nature, which merely seems to us, on account of the unity of the Substance of whose determinations nature is but the manifold, to contain a universal reference to purposes. Or if, instead of this Idealism of final causes, we wish to remain attached to the principle of the Realism of this particular kind of causality, we may set beneath natural purposes many intelligent original beings or only a single one. But so far as we have for the basis of this concept [of Realism] only empirical principles derived from the actual purposive combination in the world, we cannot on the one hand find any remedy for the discordance that nature presents in many examples in respect of unity of purpose; and on the other hand, as to the concept of a single intelligent Cause, so far as we are authorised by mere experience, we can never draw it therefrom in a manner sufficiently determined for any serviceable Theology whatever (whether theoretical or practical).

Physical Teleology impels us, it is true, to seek a Theology; but it cannot produce one, however far we may investigate nature by means of experience and, in reference to the purposive combination apparent in it, call in Ideas of Reason (which must be theoretical for physical problems). What is the use, one might well complain, of placing at the basis of all these arrangements a great Understanding incommensurable by us, and supposing it to govern the world according to design, if nature does not and cannot tell us anything of the final design? For without this we cannot refer all these natural purposes to any common point, nor can we form any teleological principle, sufficient either for cognising the purposes collected in a system, or for forming a concept of the Supreme Understanding, as Cause of such a nature, that could serve as a standard for our Judgement reflecting teleologically thereon. I should thus have an artistic Understanding for scattered purposes, but no Wisdom for a final purpose, in which final purpose nevertheless must be contained the determining ground of the said Understanding. But in the absence of a final purpose which pure Reason alone can supply (because all purposes in the world are empirically conditioned, and can contain nothing absolutely good but only what is good for this or that regarded as a contingent design), and which alone would teach me what properties, what degree, and what relation of the Supreme Cause to nature I have to think in order to judge of nature as a teleological system; how and with what right do I dare to extend at pleasure my very limited concept of that original Understanding (which I can base on my limited knowledge of the world), of the Might of that original Being in actualising its Ideas, and of its Will to do so, and complete this into the Idea of an Allwise, Infinite Being? If this is to be done theoretically, it would presuppose omniscience in me, in order to see into the purposes of nature in their whole connexion, and in addition the power of conceiving all possible plans, in comparison with which the present plan would be judged on [sufficient] grounds as the best. For without this complete knowledge of the effect I can arrive at no determinate concept of the Supreme Cause, which can only be found in the concept of an Intelligence infinite in every respect, i.e. the concept of a Deity, and so I can supply no foundation for Theology.

Hence, with every possible extension of physical Teleology, according to the propositions above laid down we may say: By the constitution and the principles of our cognitive faculty we can think of nature, in its purposive arrangements which have become known to us, in no other way than as the product of an Understanding to which it is subject. But the theoretical investigation of nature can never reveal to us whether this Understanding may not also, with the whole of nature and its production, have had a final design (which would not lie in the nature of the sensible world). On the contrary, with all our knowledge of nature it remains undecided whether that Supreme Cause is its original ground according to a final purpose, or not rather by means of an Understanding determined by the mere necessity of its nature to produce certain forms (according to the analogy of what we call the art-instinct in animals); without it being necessary to ascribe to it even wisdom, much less the highest wisdom combined with all other properties requisite for the perfection of its product.

Hence Physico-theology is a misunderstood physical Teleology, only serviceable as a preparation (propaedeutic) for Theology; and it is only adequate to this design by the aid of a foreign principle on which it can rely, and not in itself, as its name would intimate.

§ 86. Of Ethico-theology

The commonest Understanding, if it thinks over the presence of things in the world, and the existence of the world itself, cannot forbear from the judgement that all the various creatures, no matter how great the art displayed in their arrangement, and how various their purposive mutual connexion,—even the complex of their numerous systems (which we incorrectly call worlds),—would be for nothing, if there were not also men (rational beings in general). Without men the whole creation would be a mere waste, in vain, and without final purpose. But it is not in reference to man’s cognitive faculty (theoretical Reason) that the being of everything else in the world gets its worth; he is not there merely that there may be some one to contemplate the world. For if the contemplation of the world only afforded a representation of things without any final purpose, no worth could accrue to its being from the mere fact that it is known; we must presuppose for it a final purpose, in reference to which its contemplation itself has worth. Again it is not in reference to the feeling of pleasure, or to the sum of pleasures, that we think a final purpose of creation as given; i.e. we do not estimate that absolute worth by well-being or by enjoyment (whether bodily or mental), or in a word, by happiness. For the fact that man, if he exists, takes this for his final design, gives us no concept as to why in general he should exist, and as to what worth he has in himself to make his existence pleasant. He must, therefore, be supposed to be the final purpose of creation, in order to have a rational ground for holding that nature must harmonise with his happiness, if it is considered as an absolute whole according to principles of purposes.—Hence there remains only the faculty of desire; not, however, that which makes man dependent (through sensuous impulses) upon nature, nor that in respect of which the worth of his being depends upon what he receives and enjoys. But the worth which he alone can give to himself, and which consists in what he does, how and according to what principles he acts, and that not as a link in nature’s chain but in the freedom of his faculty of desire—i.e. a good will—is that whereby alone his being can have an absolute worth, and in reference to which the being of the world can have a final purpose.

The commonest judgement of healthy human Reason completely accords with this, that it is only as a moral being that man can be a final purpose of creation; if we but direct men’s attention to the question and incite them to investigate it. What does it avail, one will say, that this man has so much talent, that he is so active therewith, and that he exerts thereby a useful influence over the community, thus having a great worth both in relation to his own happy condition and to the benefit of others, if he does not possess a good will? He is a contemptible Object considered in respect of his inner self; and if the creation is not to be without any final purpose at all, he, who as man belongs to it, must, in a world under moral laws, inasmuch as he is a bad man, forfeit his subjective purpose (happiness). This is the only condition under which his existence can accord with the final purpose.

If now we meet with purposive arrangements in the world and, as Reason inevitably requires, subordinate the purposes that are only conditioned to an unconditioned, supreme, i.e. final, purpose; then we easily see in the first place that we are thus concerned not with a purpose of nature (internal to itself), so far as it exists, but with the purpose of its existence along with all its ordinances, and, consequently, with the ultimate purpose of creation, and specially with the supreme condition under which can be posited a final purpose (i.e. the ground which determines a supreme Understanding to produce the beings of the world).

Since now it is only as a moral being that we recognise man as the purpose of creation, we have in the first place a ground (at least, the chief condition) for regarding the world as a whole connected according to purposes, and as a system of final causes. And, more especially, as regards the reference (necessary for us by the constitution of our Reason) of natural purposes to an intelligent World Cause, we have one principle enabling us to think the nature and properties of this First Cause as supreme ground in the kingdom of purposes, and to determine its concept. This physical Teleology could not do; it could only lead to indeterminate concepts thereof, unserviceable alike in theoretical and in practical use.

From the principle, thus determined, of the causality of the Original Being we must not think Him merely as Intelligence and as legislative for nature, but also as legislating supremely in a moral kingdom of purposes. In reference to the highest good, alone possible under His sovereignty, viz. the existence of rational beings under moral laws, we shall think this Original Being as all-knowing: thus our inmost dispositions (which constitute the proper moral worth of the actions of rational beings of the world) will not be hid from Him. We shall think Him as all-mighty: thus He will be able to make the whole of nature accord with this highest purpose. We shall think Him as all-good, and at the same time as just: because these two properties (which when united constitute Wisdom) are the conditions of the causality of a supreme Cause of the world, as highest good, under moral laws. So also all the other transcendental properties, such as Eternity, Omnipresence, etc. [for goodness and justice are moral properties132], which are presupposed in reference to such a final purpose, must be thought in Him.—In this way moral Teleology supplies the deficiency in physical Teleology, and first establishes a Theology; because the latter, if it did not borrow from the former without being observed, but were to proceed consistently, could only found a Demonology, which is incapable of any definite concept.

But the principle of the reference of the world to a supreme Cause, as Deity, on account of the moral purposive destination of certain beings in it, does not accomplish this by completing the physico-teleological ground of proof and so taking this necessarily as its basis. It is sufficient in itself and directs attention to the purposes of nature and the investigation of that incomprehensible great art lying hidden behind its forms, in order to confirm incidentally by means of natural purposes the Ideas that pure practical Reason furnishes. For the concept of beings of the world under moral laws is a principle (a priori) according to which man must of necessity judge himself. Further, if there is in general a World Cause acting designedly and directed towards a purpose, this moral relation must be just as necessarily the condition of the possibility of a creation, as that in accordance with physical laws (if, that is, this intelligent Cause has also a final purpose). This is regarded a priori by Reason as a necessary fundamental proposition for it in its teleological judging of the existence of things. It now only comes to this, whether we have sufficient ground for Reason (either speculative or practical) to ascribe to the supreme Cause, acting in accordance with purposes, a final purpose. For it may a priori be taken by us as certain that this, by the subjective constitution of our Reason and even of the Reason of other beings as far as we can think it, can be nothing else than man under moral laws: since otherwise the purposes of nature in the physical order could not be known a priori, especially as it can in no way be seen that nature could not exist without such purposes.

Remark

Suppose the case of a man at the moment when his mind is disposed to a moral sensation. If surrounded by the beauties of nature, he is in a state of restful, serene enjoyment of his being, he feels a want, viz. to be grateful for this to some being or other. Or if another time he finds himself in the same state of mind when pressed by duties that he can and will only adequately discharge by a voluntary sacrifice, he again feels in himself a want, viz. to have thus executed a command and obeyed a Supreme Lord. Or, again; if he has in some heedless way transgressed his duty, but without becoming answerable to men, his severe self-reproach will speak to him with the voice of a judge to whom he has to give account. In a word, he needs a moral Intelligence, in order to have a Being for the purpose of his existence, which may be, conformably to this purpose, the cause of himself and of the world. It is vain to assign motives behind these feelings, for they are immediately connected with the purest moral sentiment, because gratitude, obedience, and humiliation (submission to deserved chastisement) are mental dispositions that make for duty; and the mind which is inclined towards a widening of its moral sentiment here only voluntarily conceives an object that is not in the world in order where possible to render its duty before such an one. It is therefore at least possible and grounded too in our moral disposition to represent a pure moral need of the existence of a Being, by which our morality gains strength or even (at least according to our representation) more scope, viz. a new object for its exercise. That is, [there is a need] to assume a morally-legislating Being outside the world, without any reference to theoretical proofs, still less to self-interest, from pure moral grounds free from all foreign influence (and consequently only subjective), on the mere recommendation of a pure practical Reason legislating by itself alone. And although such a mental disposition might seldom occur or might not last long, but be transient and without permanent effect, or might even pass away without any meditation on the object represented in such shadowy outline, or without care to bring it under clear concepts—there is yet here unmistakably the ground why our moral capacity, as a subjective principle, should not be contented in its contemplation of the world with its purposiveness by means of natural causes, but should ascribe to it a supreme Cause governing nature according to moral principles.—In addition, we feel ourselves constrained by the moral law to strive for a universal highest purpose which yet we, in common with the rest of nature, are incapable of attaining; and it is only so far as we strive for it that we can judge ourselves to be in harmony with the final purpose of an intelligent World Cause (if such there be). Thus is found a pure moral ground of practical Reason for assuming this Cause (since it can be done without contradiction), in order that we may no more regard that effort of Reason as quite idle, and so run the risk of abandoning it from weariness.
