Wars are fought to make the world safe for artists. It is never quite put in those terms but it is a useful way of grasping what civilized ideals are all about. The easiest way of knowing whether good has triumphed over evil is to examine the freedom of the artist.
Revolution in art is in no way connected with class revolution. Artists are members of a privileged class. Art is absurdly overrated by artists, which is understandable, but what is strange is that it is absurdly overrated by everyone else.
