But he hesitated for ten years, because, as has been said, he could not kill his affection for Wagner, the man. It takes courage to wound one's nearest and dearest, and Nietzsche, for all his lack of sentiment, was still no more than human. In the end, however, he brought himself to the heroic surgery that confronted him, and the result was "_Der Fall Wagner_". In this book all friendship and pleasant memories were put aside. Wagner was his friend of old? Very well: that was a reason for him to be all the more exact and all the more unpitying. "What does a philosopher firstly and lastly require of himself?" he asks. "To overcome his age in himself; to become timeless! With what, then, has he to fight his hardest fight? With those characteristics and ideas which most plainly stamp him as the child of his age." Herein we perceive Nietzsche's fundamental error. Deceived by Wagner's enthusiasm for Schopenhauer and his early, amateurish dabbling in philosophy, he regarded; the composer as a philosopher. But Wagner, of course, was first of all an artist, and it is the function of an artist, not to reform humanity, but to depict it as he sees it, or as his age sees it--fallacies, delusions and all. George Bernard Shaw, in his famous criticism of Shakespeare, shows us how the Bard of Avon made just such a compromise with the prevailing opinion of his time. Shakespeare, he says, was too intelligent a man to regard Rosalind as a plausible woman, but the theatre-goers of his day so regarded her and he drew her to their taste.[3] An artist who failed to make such a concession to convention would be an artist without an audience. Wagner was no Christian, but he knew that the quest of the holy grail was an idea which made a powerful appeal to nine-tenths of civilized humanity, and so he turned it into a drama. This was not conscious lack of sincerity, but merely a manifestation of the sub-conscious artistic feeling for effectiveness.[4] Therefore, it is plain that Nietzsche's whole case against Wagner is based upon a fallacy and that, in consequence, it is not to be taken too seriously. It is true enough that his book contains some remarkably acute and searching observations upon art, and that, granting his premises, his general conclusions would be correct, but we are by no means granting his premises. Wagner may have been a traitor to his philosophy, but if he had remained loyal to it, his art would have been impossible. And in view of the sublime beauty of that art we may well pardon him for not keeping the faith.
