[Footnote 1: The universal laws springing from the understanding, to which every nature must conform to become an object of experience for us, determine nothing concerning the particular form of the given reality; we cannot deduce the special laws of nature from them. Nevertheless the nature of our cognitive faculty does not allow us to accept the empirical manifoldness of our world as contingent, but impels us to regard it as purposive or adapted to our knowledge, and to look upon these special laws as if an intelligence had given them in order to make a system of experience possible.]

This, in turn, is of two kinds. An object is really or objectively purposive (perfect) when it corresponds to its nature or its determination, formally or subjectively purposive (beautiful) when it is conformed to the nature of our cognitive faculty. The perception of purpose is always accompanied by a feeling of pleasure; in the first case, where the pleasure is based on a concept of the object, it is a logical satisfaction, in the second, where it springs only from the harmony of the object with our cognitive powers, aesthetic satisfaction. The objects of the teleological and the aesthetic judgment, the purposive and the beautiful products of nature and art, constitute the desired intermediate field between nature and freedom; and here again the critical question comes up, How, in relation to these, synthetic judgments a priori are possible?

%(a) Esthetic Judgment.%—The formula holds of Kant's aesthetics as well as of his theoretical and practical philosophy, that his aim is to overcome the opposition between the empirical and the rationalistic theories, and to find a middle course of his own between the two extremes. Neither Burke nor Baumgarten satisfied him. The English aesthetics was sensational, the German, i.e., that of the Wolffian school, rationalistic. The former identified the beautiful with the agreeable, the latter identified it with the perfect or with the conformity of the object to its concept; in the one case, aesthetic appreciation is treated as sensuous pleasure, in the other, it is treated as a lower, confused kind of knowledge, its peculiar nature being in both cases overlooked. In opposition to the sensualization of aesthetic appreciation, its character as judgment must be maintained; and in opposition to its rationalization, its character as feeling. This relation of the Kantian aesthetics to that of his predecessors explains both its fundamental tendency and the elements in it which appear defective and erroneous. In any case, Kant shows himself in this field also an unapproachable master of careful analysis.

The first task of aesthetics is the careful distinction of its object from related phenomena. The beautiful has points of contact with the agreeable, the good, the perfect, the useful, and the true. It is distinguished from the true by the fact that it is not an object of knowledge, but of satisfaction. If we inquire further into the difference between the satisfaction in the beautiful and the satisfaction in the agreeable, in the good (in itself), and in the (good for something, as a means, or in the) useful, which latter three have this in common, that they are objects of appetition—of sensuous want, of moral will, of prudential desire—it becomes evident that the beautiful pleases through its mere representation (that is, independently of the real existence of the object), and that the delight in the beautiful is a contemplative pleasure. It is for contemplation only, not to be sensuously enjoyed nor put to practical use; and, further, its production is not a universal duty. Sensuous, prudential, or moral appetition has always an "interest" in the actual existence of the object; the beautiful, on the other hand, calls forth a disinterested satisfaction.

According to quality the beautiful is the object of a disinterested, free (bound by no interest), and sportive satisfaction. According to quantity and modality the judgment of taste claims universal and necessary validity, without this being based upon concepts. This posits further differences between the beautiful and the agreeable and the good. The good also pleases universally, but it pleases through concepts; the agreeable as well as the beautiful pleases without a concept, but it does not please universally.

That which pleases the reason through the concept is good; that which pleases the senses in sensation is agreeable. That which pleases universally and necessarily without a concept is beautiful. Moral judgment demands the assent of all, and its universal validity is demonstrable. The judgment concerning the agreeable is not capable of demonstration, but neither does it pretend to possess universal validity; we readily acknowledge that what is pleasant to one need not be so to every other man. In regard to the beautiful, on the contrary, we do not content ourselves with saying that tastes differ, but we expect it to please all. We expect everyone to assent to our judgment of taste, although it is able to support itself by no proofs.

Here there is a difficulty: since the judgment of taste does not express a characteristic of the object, but a state of mind in the observer, a feeling, a satisfaction, it is purely subjective; and yet it puts forth a claim to be universally communicable. The difficulty can be removed only on the assumption of a common aesthetic sense, of a corresponding organization of the powers of representation in all men, which yields the common standard for the pleasurableness of the impression. The agreeable appeals to that in man which is different in different individuals, the beautiful to that which functions alike in all; the former addresses itself to the passive sensibility, the latter to the active judgment. The agreeable—because of the non-calculable differences in our sensuous inclinations, which are in part conditioned by bodily states—possesses no universality whatever, the good possesses an objective, and the beautiful a subjective universality. The judgment concerning the agreeable has an empirical, that concerning the beautiful an a priori, determining ground: in the former case, the judgment follows the feeling, in the latter, it precedes it.

An object is considered beautiful (for, strictly speaking, we may say only this, not that it is beautiful) when its form puts the powers of the human mind in a state of harmony, brings the intuitive and rational faculties into concordant activity, and produces an agreeable proportion between the imagination and the understanding. In giving the occasion for an harmonious play of the cognitive activities (that is, for an easy combination of the manifold into unity) the beautiful object is purposive for us, for our function of apprehension; it is—here we obtain a determination of the judgment of taste from the standpoint of relation—purposive without a definite purpose. We know perfectly well that a landscape which attracts us has not been specially arranged for the purpose of delighting us, and we do not wish to find in a work of art anything of an intention to please. An object is perfect when it is purposive for itself (corresponds to its concept); useful when it is purposive for our desire (corresponds to a practical intention of man); beautiful when the arrangement of its parts is purposive for the relation between the fancy and understanding of the beholder (corresponds in an unusual degree to the conditions of our apprehension). Perfection is internal (real, objective) purposiveness, and utility is external purposiveness, both for a definite purpose; beauty, on the other hand, is purposiveness without a purpose, formal, subjective purposiveness. The beautiful pleases by its mere form. The satisfaction in the perfect is of a conceptual or intellectual kind, the satisfaction in the beautiful, emotional or aesthetic in character.

The combination of these four determinations yields an exhaustive definition of the beautiful: The beautiful is that which universally and necessarily arouses disinterested satisfaction by its mere form (purposiveness without the representation of a purpose).

Since the pleasurableness of the beautiful rests on the fact that it establishes a pleasing harmony between the imagination and the understanding, hence between sensuous and intellectual apprehension, the aesthetic attitude is possible only in sensuous-rational beings. The agreeable exists for the animal as well, and the good is an object of approval for pure spirits; but the beautiful exists for humanity alone. Kant succeeded in giving very delicate and felicitous verbal expression to these distinctions: the agreeable gratifies (vergnügt) and excites inclination (Neigung); the good is approved (gebilligt) and arouses respect (Achtung); the beautiful "pleases" (gefällt) and finds "favor" (Gunst).
