In all these discussions of the sublime and the pathetic, et cetera, Schiller exhibits a pathetically sublime faith in the possibility of settling the questions at issue by the analytic method. He writes as if the human mind were composed of air-tight compartments, wherein the various operations of reason, understanding, taste, feeling and what not, are carried on under immutable laws growing out of the nature of man. His philosophy is also dualistic. He regards 'man' as consisting of two parts joined like the Siamese twins. The one part, sensuous man, which is like unto the animals, is a part of 'nature'; the other part, the rational man, which is dowered with the birth-right of 'freedom', is outside of nature and above it. The untenableness of this conception has become since Schiller's time increasingly evident. Moreover, we have learned to look upon all things under the aspect of development and to know that man's reason, like the rest of him, is very much the creature of time and place. This being so, one finds it difficult, nowadays, to read the philosophic lucubrations of Schiller with that patience which their well-meant seriousness really deserves. Indeed he himself seems to have felt all along that there was some danger of his being carried too far away into the region of barren speculation; wherefore it was necessary, as he thought, not only to present his ideas in a popular form, but also to prove their relevancy to the practical concerns of human life. It was with this thought in mind that he finally began, instead of the 'Kallias', a series of letters to his benefactor, the Prince of Augustenburg. In a long letter of July 13, 1793, he explained his point of view. The political dream of the century, he declared, that is, the dream of recreating society upon a foundation of pure reason, had come to naught. 'Man' had shown himself unfit for freedom. His chains removed, he stood revealed as a barbarian and a slave,--the slave of unruly passion. And this notwithstanding all that the century had done for the enlightenment of his mind! Evidently the need of the hour and of the future was not so much enlightenment of the mind as discipline of the feelings. In a number of subsequent letters, admirable in style and spirit, Schiller set forth his theory of aesthetic education and his vision of the great good to be accomplished by it in the redemption of mankind from the dominion of the grosser passions. Objections were duly considered, especially the discouraging fact that, historically, aesthetic refinement has too often coincided with supineness of character and moral degeneracy. This consideration made it an important part of the problem to show how the dangers of aesthetic culture could best be counteracted.
