An artist is a deception.. ..an artist is only an artist at certain times, by an effort of will.. ..the study of nature is a cliché; isn't Manet the living proof? For although he prided himself on slavishly copying nature, he was the most inadequate painter in the world, not making a single brushstroke without reference to the old masters; for instance, he refrained from drawing fingernails because Frans Hals did not draw them.
