Art is the process of evoking pity and terror, which is not abstract at all but very human. What the self-styled modern artists are doing is a sort of unemotional pseudointellectual masturbation . . . whereas creative art is more like intercourse, in which the artist must seduce -- render emotional -- his audience, each time.
