286 THE WORLD AS IDEA. bk. iii.
of nature, from which the will must always first extort and win back the matter that belongs to all its manifestations. Further, the phenomenon of will at its higher grades always has multiplicity in its form. Even the tree is only a systematic aggregate of innumerably repeated sprouting fibres. This combination assumes greater complexity in higher forms, and the human body is an exceedingly complex system of different parts, each of which has a peculiar life of its own, vita propria, subordinate to the whole. Now that all these parts are in the proper fashion subordinate to the whole, and co-ordinate to each other, that they all work together harmoniously for the expression of the whole, nothing superfluous, nothing restricted; all these are the rare conditions, whose result is beauty, the completely expressed character of the species. So is it in nature. But how in art? One would suppose that art achieved the beautiful by imitating nature. But how is the artist to recognise the perfect work which is to be imitated, and distinguish it from the failures, if he does not anticipate the beautiful before experience? And besides this, has nature ever produced a human being perfectly beautiful in all his parts? It has accordingly been thought that the artist must seek out the beautiful parts, distributed among a number of different human beings, and out of them construct a beautiful whole; a perverse and foolish opinion. For it will be asked, how is he to know that just these forms and not others are beautiful? We also see what kind of success attended the efforts of the old German painters to achieve the beautiful by imitating nature. Observe their naked figures. No knowledge of the beautiful is possible purely a posteriori, and from mere experience; it is always, at least in part, a priori, although quite different in kind, from the forms of the principle of sufficient reason, of which we are conscious a priori. These concern the universal form of phenomena as such, as it constitutes the possi-
