In the beginning I tried to accommodate everything there that was somewhere between art and garbage and that somehow seemed important to me and a pity to throw away. After a while, some sheets in the Atlas acquired another value, after all - that is, it seemed to me that they could stand on their own terms, not only under the protection of the Atlas.

I go to the studio every day, but I dont paint every day. I love playing with my architectural models. I love making plans. I could spend my life arranging things.

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.

The urge to break with a tradition is only appropriate when you're dealing with an outdated, troublesome tradition: I never really thought about that because I take the old-fashioned approach of equating tradition with value (which may be a failing). But whatever the case, positive tradition can also provoke opposition if it's too powerful, too overwhelming, too demanding. That would basically be about the human side of wanting to hold your own.

Based on mixtures of the three primary colours, along with black and white, I come up with a certain number of possible colours and, by multiplying these by two or four, I obtain a definite number of colour fields that I multiply yet again by two, etc. But the complete realization of this project demands a great deal of time and work.

There was no special event that made me decide. I had collected some photos and the idea was in the back of my mind for a long time. It was growing and growing, so finally I said, 'I must paint this.' I come from East Germany and am not a Marxist, so of course at the time I had no sympathy for the ideas, or for the ideology that these people represented. I couldn't understand, but I was still impressed. Like everyone, I was touched. It was an exceptional moment for Germany.

Art is the pure realization of religious feeling, capacity for faith, longing for God. ... The ability to believe is our outstanding quality, and only art adequately translates it into reality. But when we assuage our need for faith with an ideology we court disaster.
