But what shows the principle of the Ideality of the purposiveness in the beauty of nature, as that which we always place at the basis of an aesthetical judgement, and which allows us to employ, as a ground of explanation for our representative faculty, no realism of purpose, is the fact that in judging beauty we invariably seek its gauge in ourselves a priori, and that our aesthetical Judgement is itself legislative in respect of the judgement whether anything is beautiful or not. This could not be, on the assumption of the Realism of the purposiveness of nature; because in that case we must have learned from nature what we ought to find beautiful, and the aesthetical judgement would be subjected to empirical principles. For in such an act of judging the important point is not, what nature is, or even, as a purpose, is in relation to us, but how we take it.
