The paint for the grey paintings was mixed beforehand and then applied with different implements - sometimes a roller, sometimes a brush. It was only after painting them that I sometimes felt that the grey was not yet satisfactory and that another layer of paint was needed.

I began in 1976, with small abstract paintings that allowed me to do what I had never let myself do: put something down at random. And then, of course, I realized that it never can be random. It was all a way of opening a door for me. If I don't know what's coming - that is, if I have no hard-and-fast image, as I have with a photographic original - then arbitrary choice and chance play an important part.

Since there is no such thing as absolute rightness and truth, we always pursue the artificial, leading, human truth. We judge and make a truth that excludes other truths. Art plays a formative part in this manufacture of truth.

I choose depending on the way I feel; randomly, in other words. When I haven't done anything for a long time, I always start small, on paper.

I wanted to say something different: the pictures are also a leave-taking, in several respects. Factually: these specific persons are dead; as a general statement, death is leave-taking. And then ideologically: a leave-taking from a specific doctrine of salvation and, beyond that, from the illusion that unacceptable circumstances of life can be changed by this conventional expedient of violent struggle.

But I would like to reach the point where I could cut up an illustrated magazine at random and see to it that the parts would each become a painting. I cannot properly explain it right now. Already now I am searching for the most boring and irrelevant photo material that I can find. And I would like to get to the point soon where this determined irrelevance could be retained, in favor of something that would be covered up otherwise by artifice.

The Atlas belongs to the Lenbachhaus in Munich - it's long since ceased to belong to me. Occasionally I run across it somewhere, and I think it's interesting because it looks different each time.
