The groans of lovers as they make love are more real than the greatest lyric poetry ever written. But they cannot be preserved. Art is not a means of pickling. […] What separates my hands when working from my direct experience of my subject is not a barrier in space like a curtain. It is more like a barrier in time. Between the idea I have and the work I produce, there is the same difference as between my action yesterday and its final consequence tomorrow. Intentions, good or bad, are no more important in art than in life. Any action is judged by its consequences.
