Every minute everything is different everywhere. It is all flowing... The duty or beauty of a painting is that there is no reason to do it nor any reason not to. It can be done as a direct act or contact with the moment and that is the moment you are awake and moving. It all passes and is never true literally as the present again leaving more work to be done.

Rauschenberg (1961), quoted in Introduction, Roberta Bernstein, catalogue The White and Black Paintings
