In order to be able to understand yourself, you must study not merely the tape-worm which you see, but also microscopic animalcules which you cannot see, and the transformation from one set of things into another, which neither you nor anybody else has ever seen, and which you certainly will never see. The same holds good with art. Wherever a true science has existed, it has been expressed by art. Since men have existed they have always separated out of all their activities, from their varied information, the chief expression of science, the knowledge of man's destination and welfare; and art, in the strict sense of the word, has been the expression of this. Since men have existed, there have always been persons particularly sensitive to the teaching of man's welfare and destiny, who have expressed in word, and upon psaltery and cymbals, their human struggle with deceit which led them aside from their true destiny, and their sufferings in this struggle, their hopes about the victory of good, their despair about the triumph of evil, and their raptures in expectation of coming welfare. Since men have existed, the true art, that which has been valued most highly by men, had no other destiny than to be the expression of science on man's destiny and welfare. Always down to the present time art has served the teaching of life (afterwards called religion), and it has only been this art which men have valued so highly. But contemporaneously with the fact that in place of the science of man's destiny and welfare appears the science of universal knowledge,--since science lost its own sense and meaning, and true science has been scornfully called religion,--true art, as an important activity of men, has disappeared. As long as the church existed, and taught men's calling and welfare, art served the church, and was true; but from the moment it left the church, and began to serve a science which served everything it met, art lost its meaning, and, notwithstanding its old-fashioned claims, and a stupid assertion that art serves merely art itself, and nothing else, it has turned out to be a trade which procures luxuries for men, and unavoidably mixes itself with choreography, culinary art, hair-dressing, and cosmetics, the producers of which may call themselves artists with as much right as the poets, painters, and musicians of our day. Looking back, we see that during thousands of years, from among thousands of millions of men who have lived, there came forth a few like Confucius, Buddha, Solon, Socrates, Solomon, Homer, Isaiah, David. True artist-producers of spiritual food seem to appear seldom among men, notwithstanding the fact that they appear, not from one caste only, but from among all men; and it is not without cause that mankind have always so highly valued them. And now it turns out that we have no longer any need of all these former great factors of art and science.
