The absence of models, in literature as in life, to say nothing of painting, is an occupational hazard for the artist, simply because models in art, in behavior, in growth of spirit and intellect--even if rejected--enrich and enlarge one's view of existence. Deadlier still, to the artist who lacks models, is the curse of ridicule, the bringing to bear on an artist's best work, especially his or her most original, most strikingly deviant, only a fund of ignorance and the presumption that as an artist's critic one's judgement is free of the restrictions imposed by prejudice, and is well informed, indeed, about all the art in the world that really matters.
