"He seems to have understood painting as a collaborative process between the artist's hand and the beholder's eye, in which the former laid down suggestive elements and the imaginative observer assembles them in his mind to make a coherent subject. Sometimes he would help the process along, Sometimes not. But he was much taken by the indeterminacy of the exercise, by forms that escaped resolution. The sobriety of the hard edge became, one has to think, a sign of conceptual banality, a weakness in the mind's eye."
Simon Schama on J.M.W. Turner
