His removal to Jena in 1791, and acquaintance with Reinhold, familiarized him with the Kantian philosophy, but he only appreciated it by halves. The bare and bald dealing with fundamental principles was at this time equally repulsive to Goethe and Schiller, the man of the world and the man of life. But Schiller did not find anywhere at that time justice done to the dignity of art, or honor to the substantial value of beauty.
The Aesthetical Essays in this volume appeared for the most part since 1792, in the "Thalia" and the "Hours" periodicals. The first "On the Ground of our Pleasure in Tragic Subjects" (1792), applies Kantian principles of the sublime to tragedy, and shows Schiller's lofty estimate of this class of poetry. With Kant he shows that the source of all pleasure is suitableness; the touching and sublime elicit this feeling, implying the existence of unsuitableness. In this article he makes the aim and source of art to consist in giving enjoyment, in pleasing. To nature pleasure is a mediate object, to art its main object. The same proposition appears in Schiller's paper on Tragic Art (1792), closely connected with the former. This article contains views of the affection of pity that seem to approximate the Aristotelian propositions about tragedy.
His views on the sublime are expressed in two papers, "The Sublime" and "The Pathetic," in which we trace considerable influence of Lessing and Winckelmann. He is led especially to strong antagonism against the French tragedy, and he indulges in a lengthy consideration of the passage of Virgil on Laocoon, showing the necessity of suffering and the pathetic in connection with moral adaptations to interest us deeply.
All these essays bespeak the poet who has tried his hand at tragedy, but in his next paper, "On Grace and Dignity," we trace more of the moralist. Those passages where he takes up a medium position between sense and reason, between Goethe and Kant, are specially attractive. The theme of this paper is the conception of grace, or the expression of a beautiful soul and dignity, or that of a lofty mind. The idea of grace has been developed more deeply and truly by Schiller than by Wieland or Winckelmann, but the special value of the paper is its constantly pointing to the ideal of a higher humanity. In it he does full justice to the sensuous and to the moral, and commencing with the beautiful nature of the Greeks, to whom sense was never mere sense, nor reason mere reason, he concludes with an image of perfected humanity in which grace and dignity are united, the former by architectonic beauty (structure), the last supported by power.
The following year, 1795, appeared his most important contribution to aesthetics, in his Aesthetical Letters.
In these letters he remarks that beauty is the work of free contemplation, and we enter with it into the world of ideas, but without leaving the world of sense. Beauty is to us an object, and yet at the same time a state of our subjectivity, because the feeling of the conditional is under that which we have of it. Beauty is a form because we consider it, and life because we feel it; in a word, it is at once our state and our art. And exactly because it is both it serves us as a triumphant proof that suffering does not exclude activity, nor matter form, nor limitation the infinite, for in the enjoyment of beauty both natures are united, and by this is proved the capacity of the infinite to be developed in the finite, and accordingly the possibility of the sublimest humanity.
The free play of the faculty of cognition which had been determined by Kant is also developed by Schiller. His representation of this matter is this: Man, as a spirit, is reason and will, self-active, determining, form-giving; this is described by Schiller as the form-instinct; man, as a sensuous being, is determinable, receptive, termed to matter; Schiller describes this as the material instinct, "Stofftrieb." In the midst between these two is situated the beautiful, in which reason and the sensuous penetrate each other, and their enjoyable product is designated by Schiller the play instinct. This expression is not happily chosen. Schiller means to describe by it the free play of the forces, activity according to nature, which is at once a joy and a happiness; he reminds us of the life of Olympus, and adds: "Man is only quite a man when he plays." Personality is that which lasts, the state of feeling is the changeable in man; he is the fixed unity remaining eternally himself in the floods of change. Man in contact with the world is to take it up in himself, but to unite with it the highest freedom and independence, and, instead of being lost in the world, to subject it to his reason. It is only by his being independent that there is reality out of him; only by being susceptible of feeling that there is reality in him. The object of sensuous instinct is life; that of the purer instinct figure; living figure or beauty is the object of the play instinct.
Only inasmuch as life is formed in the understanding and form in feeling does life win a form and form win life, and only thus does beauty arise. By beauty the sensuous man is led up to reason, the one-sided tension of special force is strung to harmony, and man made a complete whole.
Schiller adds that beauty knits together thought and feeling; the fullest unity of spirit and matter. Its freedom is not lack, but harmony, of laws; its conditions are not exclusions, inclusion of all infinity determined in itself. A true work of art generates lofty serenity and freedom of mind. Thus the aesthetic disposition bestows on us the highest of all gifts, that of a disposition to humanity, and we may call beauty our second creator.
In these letters Schiller spoke out the mildest and highest sentiments on art, and in his paper on Simple and Sentimental Poetry (1795) he constructs the ideal of the perfect poet. This is by far the most fruitful of Schiller's essays in its results. It has much that is practically applicable, and contains a very able estimate of German poetry. The writing is also very pointed and telling, because it is based upon actual perceptions, and it is interesting because the contrast drawn out throughout it between the simple and the sentimental has been referred to his own contrast with Goethe. He also wished to vindicate modern poetry, which Goethe seemed to wish to sacrifice to the antique.
The sentimental poetry is the fruit of quiet and retirement; simple poetry the child of life. One is a favor of nature; the sentimental depends on itself, the simple on the world of experience. The sentimental is in danger of extending the limits of human nature too far, of being too ideal, too mystical. Neither character exhausts the ideal of humanity, but the intimate union of both. Both are founded in human nature; the contradictions lying at their basis, when cleared in thought from the poetical faculty, are realism and idealism. These also are sides of human nature, which, when unconnected, bring forth disastrous results. Their opposition is as old as the beginning of culture, and till its end can hardly be set aside, save in the individual. The idealist is a nobler but a far less perfect being; the realist appears far less noble, but is more perfect, for the noble lies in the proof of a great capacity, but the perfect in the general attitude of the whole and in the real facts.
On the whole it may be said, taking a survey of these labors, that if Schiller had developed his ideas systematically and the unity of his intuition of the world, which were present in his feelings, and if he had based them scientifically, a new epoch in philosophy might have been anticipated. For he had obtained a view of such a future field of thought with the deep clairvoyance of his genius.
A few words may be desirable on Schiller's religious standpoint, especially in connection with his philosophical letters.
Schiller came up ten years later than Goethe, and concluded the cyclus of genius that Goethe had inaugurated. But as he was the last arrival of that productive period of tempestuous agitation, he retained more of its elements in his later life and poetry than any others who had passed through earlier agitations, such as Goethe. For Goethe cast himself free in a great measure from the early intoxication of his youthful imagination, devoting himself partly to nobler matter and partly to purer forms.
Schiller derived from the stormy times of his youth his direction to the ideal, to the hostility against the narrow spirit of civil relations, and to all given conditions of society in general. He derived from it his disposition, not to let himself be moulded by matter, but to place his own creative and determining impress on matter, not so much to grasp reality poetically and represent it poetically as to cast ideas into reality, a disposition for lively representation and strong oratorical coloring. All this he derived from the genial period, though later on somewhat modified, and carried it over into his whole life and poetry; and for this very reason he is not only together with Goethe, but before Goethe,
