Painting throughout its history has served many purposes, has been flat and has used perspective, has been framed and has been left borderless, has been explicit and has been mysterious. But one act of faith has remained a constant.... The act of faith consisted in believing that the visible contained hidden secrets, that to study the visible was to learn something more than could be seen in a glance.... Jackson Pollock was driven by a despair which was partly his and partly that of the times which nourished him, to refuse this act of faith: to insist, with all his brilliance as a painter, that there was nothing behind, that there was only that which was done to the canvas on the side facing us.
