Abstract pictures are fictive models, because they make visible a reality that we can neither see nor describe, but whose existence we can postulate.

Maybe we didn't even have a chance. The message of American Pop Art was so powerful and so optimistic. But it was also very limited, and that led us to believe that we could somehow distance ourselves from it and communicate a different intention.

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.

The photograph is the only picture that can truly convey information, even if it is technically faulty and the object can barely be identified. A painting of a murder is of no interest whatever; but a photograph of a murder fascinates everyone.

I believe I am looking for rightness. My work has so much to do with reality that I wanted to have a corresponding rightness. That excludes painting in imitation. In nature everything is always right: the structure is right, the proportions are good, the colours fit the forms. If you imitate that in painting, it becomes false.

Pictures are the idea in visual or pictorial form; and the idea has to be legible, both in the individual picture and in the collective context - which presupposes, of course, that words are used to convey information about the idea and the context. However, none of this means that pictures function as illustrations of an idea: ultimately, they are the idea. Nor is the verbal formulation of the idea a translation of the visual: it simply bears a certain resemblance to the meaning of the idea. It is an interpretation, literally a reflection.

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.
