I do not have a philosophy about retrospectives. Of course, I cannot change what I have done. What I am doing today, this I can change, in view of whatever I have done before. My retrospectives are like a series of ghosts.

All German painters have a neurosis with Germany's past: war, the postwar period most of all, East Germany. I addressed all of this in a deep depression and under great pressure. My paintings are battles, if you will.

The reality is the picture, it is most certainly not in the picture.

Spending money on art has always been frowned upon in this country - even earlier, when my and others' paintings cost almost nothing. Something is always more important. The people in charge are always peddling reasons that others seem to accept. Those who don't drink and aren't crazy, or who don't attract attention with how they behave in public, aren't noticed in art.

Unlike the expressionists, I have never been interested in renewing the world through the vehicle of art.

I love my old paintings as postulates as fresh starting points but I have to destroy them. I have to make a new manifesto.

When Michael Werner saw a painting of mine, such as Die grosse Nacht im Eimer, which back then nobody wanted and everybody thought was ridiculous, he realized that this was the right provocation, that it represented the feeling of the times in the right way.
