When I first painted a number of canvases grey all over (about eight years ago), I did so because I did not know what to paint, or what there might be to paint: so wretched a start could lead to nothing meaningful. As time went on, however, I observed differences of quality among the grey surfaces – and also that these betrayed nothing of the destructive motivation that lay behind them. The pictures began to teach me. By generalizing a personal dilemma, they resolved it.
