Kant's Critique of Judgement

The following important remark occurs here: There are three kinds of Antinomies of pure Reason, which, however, all agree in this, that they compel us to give up the otherwise very natural hypothesis that objects of sense are things in themselves, and force us to regard them merely as phenomena, and to supply to them an intelligible substrate (something supersensible of which the concept is only an Idea, and supplies no proper knowledge). Without such antinomies Reason could never decide upon accepting a principle narrowing so much the field of its speculation, and could never bring itself to sacrifices by which so many otherwise brilliant hopes must disappear. For even now when, by way of compensation for these losses, a greater field in a practical aspect opens out before it, it appears not to be able without grief to part from those hopes, and disengage itself from its old attachment.

That there are three kinds of antinomies has its ground in this, that there are three cognitive faculties,—Understanding, Judgement, and Reason; of which each (as a superior cognitive faculty) must have its a priori principles. For Reason, in so far as it judges of these principles and their use, inexorably requires, in respect of them all, the unconditioned for the given conditioned; and this can never be found if we consider the sensible as belonging to things in themselves, and do not rather supply to it, as mere phenomenon, something supersensible (the intelligible substrate of nature both external and internal) as the reality in itself [Sache an sich selbst]. There are then: (1) For the cognitive faculty an antinomy of Reason in respect of the theoretical employment of the Understanding extended to the unconditioned; (2) for the feeling of pleasure and pain an antinomy of Reason in respect of the aesthetical employment of the Judgement; and (3) for the faculty of desire an antinomy in respect of the practical employment of the self-legislative Reason; so far as all these faculties have their superior principles a priori, and, in conformity with an inevitable requirement of Reason, must judge and be able to determine their Object, unconditionally according to those principles.

As for the two antinomies of the theoretical and practical employment of the superior cognitive faculties, we have already shown their unavoidableness, if judgements of this kind are not referred to a supersensible substrate of the given Objects, as phenomena; and also the possibility of their solution, as soon as this is done. And as for the antinomies in the employment of the Judgement, in conformity with the requirements of Reason, and their solution which is here given, there are only two ways of avoiding them. Either: we must deny that any a priori principle lies at the basis of the aesthetical judgement of taste; we must maintain that all claim to necessary universal agreement is a groundless and vain fancy, and that a judgement of taste only deserves to be regarded as correct because it happens that many people agree about it; and this, not because we assume an a priori principle behind this agreement, but because (as in the taste of the palate) of the contingent similar organisation of the different subjects. Or: we must assume that the judgement of taste is really a disguised judgement of Reason upon the perfection discovered in a thing and the reference of the manifold in it to a purpose, and is consequently only called aesthetical on account of the confusion here attaching to our reflection, although it is at bottom teleological.

In the latter case we could declare the solution of the antinomies by means of transcendental Ideas to be needless and without point, and thus could harmonise these laws of taste with Objects of sense, not as mere phenomena but as things in themselves. But we have shown in several places in the exposition of judgements of taste how little either of these expedients will satisfy.

However, if it be granted that our deduction at least proceeds by the right method, although it be not yet plain enough in all its parts, three Ideas manifest themselves. First, there is the Idea of the supersensible in general, without any further determination of it, as the substrate of nature. Secondly, there is the Idea of the same as the principle of the subjective purposiveness of nature for our cognitive faculty. And thirdly, there is the Idea of the same as the principle of the purposes of freedom, and of the agreement of freedom with its purposes in the moral sphere.
