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).
