Nowhere in my collection do I, say, have a Auguste Renoir painting. Because everybody knows that this is a good painter without me having to demonstrate it.

No one who looks at my paintings can see whether a painting is upside down or not anymore. I've made or developed so many image models that some people have given up trying to keep track of me. But others have only one or two ways of doing things and are successful with that.

I don't paint over my paintings with black paint. I paint black paintings. It isn't because I'm sad, just as I didn't paint red paintings yesterday because I was happy. Nor will I paint yellow paintings tomorrow because I'm jealous.

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.

A citizen sticks to conventions, does whatever is social. Artists, of course, must reject all conventions. I see no differently in reconciling the best of both of these worlds.

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.

I became an artist because of the possibility it gave me to develop in another way, because I didn't want to follow the same lines the others around me did. I was educated in the former German Democratic Republic, which meant that an individual figure had to be... like a soldier in the army.
