My own general thesis was somewhat to this effect: that Artists have worried the world by being wantonly, needlessly, and gratuitously progressive. Politicians have to be progressive; that is, they have to live in the future, because they know they have done nothing but evil in the past. But Artists, who have been right from the beginning of the world, who were, perhaps, the only people who were right even in the beginning of the world, decorating pottery or designing rude frescoes on the rock when other people were fighting or offering human sacrifice, they have no right to despise their own past.
