Note 141 — PART II CRITIQUE OF THE TELEOLOGICAL JUDGEMENT (continued 3)

Analogy (in a qualitative signification) is the identity of the relation between reasons and consequences (causes and effects), so far as it is to be found, notwithstanding the specific difference of the things or those properties in them which contain the reason for like consequences (i.e. considered apart from this relation). Thus we conceive of the artificial constructions of beasts by comparing them with those of men; by comparing the ground of those effects brought about by the former, which we do not know, with the ground of similar effects brought about by men (reason), which we do know; i.e. we regard the ground of the former as an analogon of reason. We then try at the same time to show that the ground of the artisan faculty of beasts, which we call instinct, specifically different as it is in fact from reason, has yet a similar relation to its effect (the buildings of the beaver as compared with those of men).—But then I cannot therefore conclude that because man uses reason for his building, the beaver must have the like, and call this a conclusion according to analogy. But from the similarity of the mode of operation of beasts (of which we cannot immediately perceive the ground) to that of men (of which we are immediately conscious), we can quite rightly conclude according to analogy, that beasts too act in accordance with representations (not as Descartes has it, that they are machines), and that despite their specific distinction they are yet (as living beings) of the same genus as man. The principle of our right so to conclude consists in the sameness of the ground for reckoning beasts in respect of the said determination in the same genus with men, regarded as men, so far as we can externally compare them with one another in accordance with their actions. There is par ratio. Just so I can conceive, according to the analogy of an Understanding, the causality of the supreme World-Cause, by comparing its purposive products in the world with the artificial works of men; but I cannot conclude according to analogy to those properties in it [which are in man], because here the principle of the possibility of such a method of reasoning entirely fails, viz. the paritas rationis for counting the Supreme Being in one and the same genus with man (in respect of the causality of both). The causality of the beings of the world, which is always sensibly conditioned (as is causality through Understanding) cannot be transferred to a Being which has in common with them no generic concept save that of Thing in general.
