"We are perhaps nearing an understanding of the meaning of chance in art. It would, of course, be unbearable if our intentions were regularly frustrated. Yet there is something terribly arid, not to say mechanistic, in the idea of a world where all our purposes results in predictable consequences, where we are completely transparent to ourselves and where intentions always result in expected actions. We value the degree of interference and human intentional activity offered by the unconscious, by language, by the apparatus of the camera or computer, by the instruction performed 'blind.' In short we desire to see what will happen.
