Following the guiding thread of the categories, he declares that the aesthetical judgement about Beauty is according to quality disinterested; a point which had been laid down by such different writers as Hutcheson and Moses Mendelssohn. As to quantity, the judgement about beauty gives universal satisfaction, although it is based on no definite concept. The universality is only subjective; but still it is there. The maxim Trahit sua quemque voluptas does not apply to the pleasure afforded by a pure judgement about beauty. As to relation, the characteristic of the object called beautiful is that it betrays a purposiveness without definite purpose. The pleasure is a priori, independent on the one hand of the charms of sense or the emotions of mere feeling, as Winckelmann had already declared; and on the other hand is a pleasure quite distinct from that taken which we feel when viewing perfection, with which Wolff and Baumgarten had identified it. By his distinction between free and dependent beauty, which we also find in the pages of Hutcheson, Kant further develops his doctrine of the freedom of the pure judgement of taste from the thraldom of concepts.
Finally, the satisfaction afforded by the contemplation of a beautiful object is a necessary satisfaction. This necessity is not, to be sure, theoretical like the necessity attaching to the Law of Causality; nor is it a practical necessity as is the need to assume the Moral Law as the guiding principle of conduct. But it may be called exemplary; that is, we may set up our satisfaction in a beautiful picture as setting an example to be followed by others. It is plain, however, that this can only be assumed under certain presuppositions. We must presuppose the idea of a sensus communis or common sense in which all men share. As knowledge admits of being communicated to others, so also does the feeling for beauty. For the relation between the cognitive faculties requisite for Taste is also requisite for Intelligence or sound Understanding, and as we always presuppose the latter to be the same in others as in ourselves, so may we presuppose the former.
The analysis of the Sublime which follows that of the Beautiful is interesting and profound; indeed Schopenhauer regarded it as the best part of the Critique of the Aesthetical Judgement. The general characteristics of our judgements about the Sublime are similar to those already laid down in the case of the Beautiful; but there are marked differences in the two cases. If the pleasure taken in beauty arises from a feeling of the purposiveness of the object in its relation to the subject, that in sublimity rather expresses a purposiveness of the subject in respect of the object. Nothing in nature is sublime; and the sublimity really resides in the mind and there alone. Indeed, as true Beauty is found, properly speaking, only in beauty of form, the idea of sublimity is excited rather by those objects which are formless and exhibit a violation of purpose.
A distinction not needed in the case of the Beautiful becomes necessary when we proceed to further analyse the Sublime. For in aesthetical judgements about the Beautiful the mind is in restful contemplation; but in the case of the Sublime a mental movement is excited (pp. 105 and 120). This movement, as it is pleasing, must involve a purposiveness in the harmony of the mental powers; and the purposiveness may be either in reference to the faculty of cognition or to that of desire. In the former case the sublime is called the Mathematically Sublime—the sublime of mere magnitude—the absolutely great; in the latter it is the sublime of power, the Dynamically Sublime. Gioberti, an Italian writer on the philosophy of Taste, has pushed this distinction so far as to find in it an explanation of the relation between Beauty and Sublimity. “The dynamical Sublime,” he says, “creates the Beautiful; the mathematical Sublime contains it,” a remark with which probably Kant would have no quarrel.
In both cases, however, we find that the feeling of the Sublime awakens in us a feeling of the supersensible destination of man. “The very capacity of conceiving the sublime,” he tells us, “indicates a mental faculty that far surpasses every standard of sense.” And to explain the necessity belonging to our judgements about the sublime, Kant points out that as we find ourselves compelled to postulate a sensus communis to account for the agreement of men in their appreciation of beautiful objects, so the principle underlying their consent in judging of the sublime is “the presupposition of the moral feeling in man.” The feeling of the sublimity of our own moral destination is the necessary prerequisite for forming such judgements. The connexion between Beauty and Goodness involved to a Greek in the double sense of the word καλόν is developed by Kant with keen insight. To feel interest in the beauty of Nature he regards as a mark of a moral disposition, though he will not admit that the same inference may be drawn as to the character of the art connoisseur (§ 42). But it is specially with reference to the connexion between the capacity for appreciating the Sublime, and the moral feeling, that the originality of Kant’s treatment becomes apparent.
The objects of nature, he continues, which we call sublime, inspire us with a feeling of pain rather than of pleasure; as Lucretius has it—
Me quaedam divina voluptas
Percipit atque horror.
But this “horror” must not inspire actual fear. As no extraneous charm must mingle with the satisfaction felt in a beautiful object, if the judgement about beauty is to remain pure; so in the case of the sublime we must not be afraid of the object which yet in certain aspects is fearful.
This conception of the feelings of sublimity excited by the loneliness of an Alpine peak or the grandeur of an earthquake is now a familiar one; but it was not so in Kant’s day. Switzerland had not then become the recreation-ground of Europe; and though natural beauty was a familiar topic with poets and painters it was not generally recognised that taste has also to do with the sublime. De Saussure’s Travels, Haller’s poem Die Alpen, and this work of Kant’s mark the beginning of a new epoch in our ways of looking at the sublime and terrible aspects of Nature. And it is not a little remarkable that the man who could write thus feelingly about the emotions inspired by grand and savage scenery, had never seen a mountain in his life. The power and the insight of his observations here are in marked contrast to the poverty of some of his remarks about the characteristics of beauty. For instance, he puts forward the curious doctrine that colour in a picture is only an extraneous charm, and does not really add to the beauty of the form delineated, nay rather distracts the mind from it. His criticisms on this point, if sound, would make Flaxman a truer artist than Titian or Paolo Veronese. But indeed his discussion of Painting or Music is not very appreciative; he was, to the end, a creature of pure Reason.
Upon the analysis he gives of the Arts, little need be said here. Fine Art is regarded as the Art of Genius, “that innate mental disposition through which Nature gives the rule to Art” (§ 46). Art differs from Science in the absence of definite concepts in the mind of the artist. It thus happens that the great artist can rarely communicate his methods; indeed he cannot explain them even to himself. Poeta nascitur, non fit; and the same is true in every form of fine art. Genius is, in short, the faculty of presenting aesthetical Ideas; an aesthetical Idea being an intuition of the Imagination, to which no concept is adequate. And it is by the excitation of such ineffable Ideas that a great work of art affects us. As Bacon tells us, “that is the best part of Beauty which a picture cannot express; no, nor the first sight of the eye.” This characteristic of the artistic genius has been noted by all who have thought upon art; more is present in its productions than can be perfectly expressed in language. As Pliny said of Timanthus the painter of Iphigenia, “In omnibus ejus operibus intelligitur plus super quam pingitur.” But this genius requires to be kept in check by taste; quite in the spirit of the σωφροσύνη of the best Greek art, Kant remarks that if in a work of art some feature must be sacrificed, it is better to lose something of genius than to violate the canons of taste. It is in this self-mastery that “the sanity of true genius” expresses itself.
The main question with which the Critique of Judgement is concerned is, of course, the question as to the purposiveness, the Zweckmässigkeit, exhibited by nature. That nature appears to be full of purpose is mere matter of fact. It displays purposiveness in respect of our faculties of cognition, in those of its phenomena which we designate beautiful. And also in its organic products we observe methods of operation which we can only explain by describing them as processes in which means are used to accomplish certain ends, as processes that are purposive. In our observation
