Rene Magritte by Duane Michals. "The mind loves the unknown. It loves images whose meaning is unknown, since the meaning of the mind itself is unknown." . . . "My painting is visible images which conceal nothing... they evoke mystery and indeed when one sees one of my pictures, one asks oneself this simple question 'What does that mean'? It does not mean anything, because mystery means nothing either, it is unknowable."
