Hence it is only under the presupposition that there is a common sense (by which we do not understand an external sense, but the effect resulting from the free play of our cognitive powers)—it is only under this presupposition, I say, that the judgement of taste can be laid down.
§ 21. Have we ground for presupposing a common sense?
Cognitions and judgements must, along with the conviction that accompanies them, admit of universal communicability; for otherwise there would be no harmony between them and the Object, and they would be collectively a mere subjective play of the representative powers, exactly as scepticism would have it. But if cognitions are to admit of communicability, so must also the state of mind,—i.e. the accordance of the cognitive powers with a cognition generally, and that proportion of them which is suitable for a representation (by which an object is given to us) in order that a cognition may be made out of it—admit of universal communicability. For without this as the subjective condition of cognition, knowledge as an effect could not arise. This actually always takes place when a given object by means of Sense excites the Imagination to collect the manifold, and the Imagination in its turn excites the Understanding to bring about a unity of this collective process in concepts. But this accordance of the cognitive powers has a different proportion according to the variety of the Objects which are given. However, it must be such that this internal relation, by which one mental faculty is excited by another, shall be generally the most beneficial for both faculties in respect of cognition (of given objects); and this accordance can only be determined by feeling (not according to concepts). Since now this accordance itself must admit of universal communicability, and consequently also our feeling of it (in a given representation), and since the universal communicability of a feeling presupposes a common sense, we have grounds for assuming this latter. And this common sense is assumed without relying on psychological observations, but simply as the necessary condition of the universal communicability of our knowledge, which is presupposed in every Logic and in every principle of knowledge that is not sceptical.
§ 22. The necessity of the universal agreement that is thought in a judgement of taste is a subjective necessity, which is represented as objective under the presupposition of a common sense
In all judgements by which we describe anything as beautiful, we allow no one to be of another opinion; without however grounding our judgement on concepts but only on our feeling, which we therefore place at its basis not as a private, but as a communal feeling.[40] Now this common sense cannot be grounded on experience; for it aims at justifying judgements which contain an ought. It does not say that every one will agree with my judgement, but that he ought. And so common sense, as an example of whose judgement I here put forward my judgement of taste and on account of which I attribute to the latter an exemplary validity, is a mere ideal norm, under the supposition of which I have a right to make into a rule for every one a judgement that accords therewith, as well as the satisfaction in an Object expressed in such judgement. For the principle, which concerns the agreement of different judging persons, although only subjective, is yet assumed as subjectively universal (an Idea necessary for every one); and thus can claim universal assent (as if it were objective) provided we are sure that we have correctly subsumed [the particulars] under it.
This indeterminate norm of a common sense is actually presupposed by us; as is shown by our claim to lay down judgements of taste. Whether there is in fact such a common sense, as a constitutive principle of the possibility of experience, or whether a yet higher principle of Reason makes it only into a regulative principle for producing in us a common sense for higher purposes: whether therefore Taste is an original and natural faculty, or only the Idea of an artificial one yet to be acquired, so that a judgement of taste with its assumption of a universal assent in fact, is only a requirement of Reason for producing such harmony of sentiment; whether the “ought,” i.e. the objective necessity of the confluence of the feeling of any one man with that of every other, only signifies the possibility of arriving at this accord, and the judgement of taste only affords an example of the application of this principle: these questions we have neither the wish nor the power to investigate as yet; we have now only to resolve the faculty of taste into its elements in order to unite them at last in the Idea of a common sense.
EXPLANATION OF THE BEAUTIFUL RESULTING FROM THE FOURTH MOMENT
The beautiful is that which without any concept is cognised as the object of a necessary satisfaction.
GENERAL REMARK ON THE FIRST SECTION OF THE ANALYTIC
If we seek the result of the preceding analysis we find that everything runs up into this concept of Taste, that it is a faculty for judging an object in reference to the Imagination’s free conformity to law. Now if in the judgement of taste the Imagination must be considered in its freedom, it is in the first place not regarded as reproductive, as it is subject to the laws of association, but as productive and spontaneous (as the author of arbitrary forms of possible intuition). And although in the apprehension of a given object of sense it is tied to a definite form of this Object, and so far has no free play (such as that of poetry) yet it may readily be conceived that the object can furnish it with such a form containing a collection of the manifold, as the Imagination itself, if it were left free, would project in accordance with the conformity to law of the Understanding in general. But that the imaginative power should be free and yet of itself conformed to law, i.e. bringing autonomy with it, is a contradiction. The Understanding alone gives the law. If, however, the Imagination is compelled to proceed according to a definite law, its product in respect of form is determined by concepts as to what it ought to be. But then, as is above shown, the satisfaction is not that in the Beautiful, but in the Good (in perfection, at any rate in mere formal perfection); and the judgement is not a judgement of taste. Hence it is a conformity to law without a law; and a subjective agreement of the Imagination and Understanding,—without such an objective agreement as there is when the representation is referred to a definite concept of an object,—can subsist along with the free conformity to law of the Understanding (which is also called purposiveness without purpose) and with the peculiar feature of a judgement of taste.
