Hence beauty is freedom in the appearance. In a letter of February 23, 1793, he applies his dogma to an exposition of the relation between nature and art. The problem of the artist in the representation of an object, so the theory runs, is to convey a suggestion of freedom, that is, of not-being-determined-from-without. This he can only do by making the object appear to be determined from within, in other words, to follow its own law. It must have a law and obey it, while seeming to be free. The law of the object is what is disclosed by technique, which is thus the basis of our impression of freedom. Starting from Kant's saying that nature is beautiful when it looks like art, and art beautiful when it looks like nature, Schiller gives a large number of concrete illustrations of his theory. Thus a vase is beautiful when, without prejudice to the vase-idea, it looks like a free play of nature. A birch is beautiful when it is tall and slender, an oak when it is crooked; the shape in either case expressing the nature of the tree when it follows nature's law. 'Therefore', he concludes his illustrations, 'the empire of taste is the empire of freedom; the beautiful world of sense being the happiest symbol of what the moral world should be, and every beautiful object about me being a happy citizen who calls out: Be free like me.' It did not escape our theorist that his hard-won criterion of beauty was after all, apparently, an idea of the reason. He was however prepared to meet this difficulty and promised to do so in a future letter. But the aesthetic correspondence with Körner was not continued beyond February. The project of the 'Kallias' continued for some time longer to occupy Schiller's mind, but a fresh attack of illness intervened, and when he was again able to work he turned his mind to an essay upon 'Winsomeness and Dignity' (_Anmut und Würde_). It was written in May and June, 1793, and printed soon afterwards in the _New Thalia_. In this essay we can observe a growing independence of thought and an amazing gift for the analysis of subtle impressions. In the main it is lucid enough, especially when one calls in the aid of the preceding letters to Körner; but portions are hard reading. To give the gist of it in a few words is next to impossible, because it is so largely taken up with superfine distinctions in the meaning of words for which our language has at best but rough equivalents.
