Abstract
There exists no isolated branch of learning. Kant's theory of beauty must also be related to some other branch of learning. In his book "Critique of Judgement" (1790) his theory of beauty is put in relation to that of nature and moral. The form of this type of relation is the systematization. On the other hand his theory of beauty in the 1770's is essentially connected with the logic. The form of this relation is the equivalence. The latter form of the relation which his theory of beauty has to the logic secretly comes into his discourse in his "Critique of Judgement" which adopts the former structure of the relation. Thus Kant's thery of beauty in 1790 contains a double structure of the discourse.
