Kant's Critique of Judgement PDF complete
--"All technically-practical rules (i.e., those of art and skill generally, or even of prudence, as a skill in exercising an influence over men and their wills) must, so far as their principles rest upon concepts, be reckoned only as corollaries to theoretical philosophy. For they only touch the possibility of things according to concepts of nature, and this embraces, not alone the means discoverable in nature for the purpose, but even the will itself (as a faculty of desire, and consequently a natural faculty), so far as it is determinable on these rules by natural motives. Still these practical rules are not called laws (like physical laws), but only precepts."
