The character of the artist doesn't enter into the nature of the art. Eliot said that art is the escape from personality, which I think is right. We know that Velรกzquez embezzled money from the Spanish court and wanted power and so on, but you can't see this in his art.
Lucian FreudA painter's tastes must grow out of what so obsesses him in life that he never has to ask himself what it is suitable for him to do in art.
