This perplexity about a principle (whether it is subjective or objective) presents itself mainly in those judgements that we call aesthetical, which concern the Beautiful and the Sublime of Nature or of Art. And, nevertheless, the critical investigation of a principle of Judgement in these is the most important part in a Critique of this faculty. For although they do not by themselves contribute to the knowledge of things, yet they belong to the cognitive faculty alone, and point to an immediate reference of this faculty to the feeling of pleasure or pain according to some principle _a priori_; without confusing this with what may be the determining ground of the faculty of desire, which has its principles _a priori_ in concepts of Reason.--In the logical judging of nature, experience exhibits a conformity to law in things, to the understanding or to the explanation of which the general concept of the sensible does not attain; here the Judgement can only derive from itself a principle of the reference of the natural thing to the unknowable supersensible (a principle which it must only use from its own point of view for the cognition of nature). And so, though in this case such a principle _a priori_ can and must be applied to the _cognition_ of the beings of the world, and opens out at the same time prospects which are advantageous for the practical Reason, yet it has no immediate reference to the feeling of pleasure and pain. But this reference is precisely the puzzle in the principle of Judgement, which renders a special section for this faculty necessary in the Critique; since the logical judging according to concepts (from which an immediate inference can never be drawn to the feeling of pleasure and pain) along with their critical limitation, has at all events been capable of being appended to the theoretical part of Philosophy. The examination of the faculty of taste, as the aesthetical Judgement, is not here planned in reference to the formation or the culture of taste (for this will take its course in the future as in the past without any such investigations), but merely in a transcendental point of view. Hence, I trust that as regards the deficiency of the former purpose it will be judged with indulgence, though in the latter point of view it must be prepared for the severest scrutiny. But I hope that the great difficulty of solving a problem so involved by nature may serve as excuse for some hardly avoidable obscurity in its solution, if only it be clearly established that the principle is correctly stated. I grant that the mode of deriving the phenomena of the Judgement from it has not all the clearness which might be rightly demanded elsewhere, viz. in the case of cognition according to concepts; but I believe that I have attained to it in the second part of this work.
