Remark
This Deduction is thus easy, because it has no need to justify the objective reality of any concept, for Beauty is not a concept of the Object and the judgement of taste is not cognitive. It only maintains that we are justified in presupposing universally in every man those subjective conditions of the Judgement which we find in ourselves; and further, that we have rightly subsumed the given Object under these conditions. The latter has indeed unavoidable difficulties which do not beset the logical Judgement. There we subsume under concepts, but in the aesthetical Judgement under a merely sensible relation between the Imagination and Understanding mutually harmonising in the representation of the form of the Object,—in which case the subsumption may easily be fallacious. Yet the legitimacy of the claim of the Judgement in counting upon universal assent is not thus annulled; it reduces itself merely to the correctness of the principle of judging validly for every one from subjective grounds. For as to the difficulty or doubt concerning the correctness of the subsumption under that principle, it makes the legitimacy of the claim of an aesthetical judgement in general to such validity and the principle of the same, as little doubtful, as the like faulty (though neither so commonly nor readily faulty) subsumption of the logical Judgement under its principle can make the latter, an objective principle, doubtful. But if the question were to be, how is it possible to assume nature a priori to be a complex of objects of taste? this problem has reference to Teleology, because it must be regarded as a purpose of nature essentially belonging to its concept to exhibit forms that are purposive for our Judgement. But the correctness of this latter assumption is very doubtful, whereas the efficacy of natural beauties is patent to experience.
§ 39. Of the communicability of a Sensation
If sensation, as the real in perception, is related to knowledge, it is called sensation of the senses; and its specific quality may be represented as generally communicable in a uniform way, if we assume that every one has senses like our own. But this cannot at all be presupposed of any single sensation. To a man who is deficient in the sense of smell, this kind of sensation cannot be communicated; and even if it is not wholly deficient, we cannot be certain that he gets exactly the same sensation from a flower that we have. But even more must we represent men as differing in respect of the pleasantness or unpleasantness involved in the sensation from the same object of sense; and it is absolutely not to be required that every man should take pleasure in the same objects. Pleasure of this kind, because it comes into the mind through the senses, in respect of which therefore we are passive, we may call the pleasure of enjoyment.
Satisfaction in an action because of its moral character is on the other hand not the pleasure of enjoyment, but of spontaneity and its accordance with the Idea of its destination. But this feeling, called moral, requires concepts, and presents not free purposiveness, but purposiveness that is conformable to law; it therefore admits of being universally communicated only by means of Reason, and, if the pleasure is to be homogeneous for every one, by very definite practical concepts of Reason.
Pleasure in the Sublime in nature, regarded as a pleasure of rational contemplation, also makes claim to universal participation; but it presupposes, besides, a different feeling, viz. that of our supersensible destination, which, however obscurely, has a moral foundation. But that other men will take account of it, and will find a satisfaction in the consideration of the wild greatness of nature (that certainly cannot be ascribed to its aspect, which is rather terrifying), I am not absolutely justified in supposing. Nevertheless, in consideration of the fact that on every suitable occasion regard should be had to these moral dispositions, I can impute such satisfaction to every man, but only by means of the moral law which on its side again is based on concepts of Reason.
On the contrary, pleasure in the Beautiful is neither a pleasure of enjoyment nor of a law-abiding activity, nor even of rational contemplation in accordance with Ideas, but of mere reflection. Without having as rule any purpose or fundamental proposition, this pleasure accompanies the ordinary apprehension of an object by the Imagination, as faculty of intuition, in relation with the Understanding, as faculty of concepts, by means of a procedure of the Judgement which it must also exercise on behalf of the commonest experience; only that in the latter case it is in order to perceive an empirical objective concept, in the former case (in aesthetical judgements) merely to perceive the accordance of the representation with the harmonious (subjectively purposive) activity of both cognitive faculties in their freedom, i.e. to feel with pleasure the mental state produced by the representation. This pleasure must necessarily depend for every one on the same conditions, for they are subjective conditions of the possibility of a cognition in general; and the proportion between these cognitive faculties requisite for Taste is also requisite for that ordinary sound Understanding which we have to presuppose in every one. Therefore he who judges with taste (if only he does not go astray in this act of consciousness and mistake matter for form or charm for beauty) may impute to every one subjective purposiveness, i.e. his satisfaction in the Object, and may assume his feeling to be universally communicable and that without the mediation of concepts.
§ 40. Of Taste as a kind of sensus communis
We often give to the Judgement, if we are considering the result rather than the act of its reflection, the name of a sense, and we speak of a sense of truth, or of a sense of decorum, of justice, etc. And yet we know, or at least we ought to know, that these concepts cannot have their place in Sense, and further, that Sense has not the least capacity for expressing universal rules; but that no representation of truth, fitness, beauty, or justice, and so forth, could come into our thoughts if we could not rise beyond Sense to higher faculties of cognition. The common Understanding of men, which, as the mere sound (not yet cultivated) Understanding, we regard as the least to be expected from any one claiming the name of man, has therefore the doubtful honour of being given the name of common sense (sensus communis); and in such a way that by the name common (not merely in our language, where the word actually has a double signification, but in many others) we understand vulgar, that which is everywhere met with, the possession of which indicates absolutely no merit or superiority.
But under the sensus communis we must include the Idea of a communal sense, i.e. of a faculty of judgement, which in its reflection takes account (a priori) of the mode of representation of all other men in thought; in order as it were to compare its judgement with the collective Reason of humanity, and thus to escape the illusion arising from the private conditions that could be so easily taken for objective, which would injuriously affect the judgement. This is done by comparing our judgement with the possible rather than the actual judgements of others, and by putting ourselves in the place of any other man, by abstracting from the limitations which contingently attach to our own judgement. This, again, is brought about by leaving aside as much as possible the matter of our representative state, i.e. sensation, and simply having respect to the formal peculiarities of our representation or representative state. Now this operation of reflection seems perhaps too artificial to be attributed to the faculty called common sense; but it only appears so, when expressed in abstract formulae. In itself there is nothing more natural than to abstract from charm or emotion if we are seeking a judgement that is to serve as a universal rule.
