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).
_Hume_[121] 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 _Linnaeus_[123] 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’s_[125] 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
