Many questions bearing on art and relating to the beautiful had been propounded before, even as far back as Plotinus, Plato, and Socrates, but recent times have been the real cradle of aesthetics as a science. Modern philosophy was the first to recognize that beauty in art is one of the means by which the contradictions can be removed between mind considered in its abstract and absolute existence and nature constituting the world of sense, bringing back these two factors to unity.
Kant was the first who felt the want of this union and expressed it, but without determining its conditions or expressing it scientifically. He was impeded in his efforts to effect this union by the opposition between the subjective and the objective, by his placing practical reason above theoretical reason, and he set up the opposition found in the moral sphere as the highest principle of morality. Reduced to this difficulty, all that Kant could do was to express the union under the form of the subjective ideas of reason, or as postulates to be deduced from the practical reason, without their essential character being known, and representing their realization as nothing more than a simple you ought, or imperative "Du sollst."
In his teleological judgment applied to living beings, Kant comes, on the contrary, to consider the living organism in such wise that, the general including the particular, and determining it as an end, consequently the idea also determines the external, the compound of the organs, not by an act springing from without but issuing from within. In this way the end and the means, the interior and exterior, the general and particular, are confounded in unity. But this judgment only expresses a subjective act of reflection, and does not throw any light on the object in itself. Kant has the same view of the aesthetic judgment. According to him the judgment does not proceed either from reason, as the faculty of general ideas, or from sensuous perception, but from the free play of the reason and of the imagination. In this analysis of the cognitive faculty, the object only exists relatively to the subject and to the feeling of pleasure or the enjoyment that it experiences.
The characteristics of the beautiful are, according to Kant:—
1. The pleasure it procures is free from interest.
2. Beauty appears to us as an object of general enjoyment, without awakening in us the consciousness of an abstract idea and of a category of reason to which we might refer our judgment.
3. Beauty ought to embrace in itself the relation of conformity to its end, but in such a way that this conformity may be grasped without the idea of the end being offered to our mind.
4. Though it be not accompanied by an abstract idea, beauty ought to be acknowledged as the object of a necessary enjoyment.
A special feature of all this system is the indissoluble unity of what is supposed to be separated in consciousness. This distinction disappears in the beautiful, because in it the general and the particular, the end and the means, the idea and the object, mentally penetrate each other completely. The particular in itself, whether it be opposed to itself or to what is general, is something accidental. But here what may be considered as an accidental form is so intimately connected with the general that it is confounded and identified with it. By this means the beautiful in art presents thought to us as incarnate. On the other hand, matter, nature, the sensuous as themselves possessing measure, end, and harmony, are raised to the dignity of spirit and share in its general character. Thought not only abandons its hostility against nature, but smiles in her. Sensation and enjoyment are justified and sanctified, so that nature and liberty, sense and ideas, find their justification and their sanctification in this union. Nevertheless this reconciliation, though seemingly perfect, is stricken with the character of subjectiveness. It cannot constitute the absolutely true and real.
Such is an outline of the principal results of Kant's criticism, and Hegel passes high praise on the profoundly philosophic mind of Schiller, who demanded the union and reconciliation of the two principles, and who tried to give a scientific explanation of it before the problem had been solved by philosophy. In his "Letters on Aesthetic Education," Schiller admits that man carries in himself the germ of the ideal man which is realized and represented by the state. There are two ways for the individual man to approach the ideal man; first, when the state, considered as morality, justice, and general reason, absorbs the individualities in its unity; secondly, when the individual rises to the ideal of his species by the perfecting of himself. Reason demands unity, conformity to the species; nature, on the other hand, demands plurality and individuality; and man is at once solicited by two contrary laws. In this conflict, aesthetic education must come in to effect the reconciliation of the two principles; for, according to Schiller, it has as its end to fashion and polish the inclinations and passions so that they may become reasonable, and that, on the other hand, reason and freedom may issue from their abstract character, may unite with nature, may spiritualize it, become incarnate, and take a body in it. Beauty is thus given as the simultaneous development of the rational and of the sensuous, fused together, and interpenetrated one by the other, an union that constitutes in fact true reality.
