The grey is certainly inspired by the photo-paintings, and, of course, it's related to the fact that I think grey is an important colour - the ideal colour for indifference, fence-sitting, keeping quiet, despair. In other words, for states of being and situations that affect one, and for which one would like to find a visual expression.

Above all, it's never blind chance: it's a chance that is always planned, but also always surprising. And I need it in order to carry on, in order to eradicate my mistakes, to destroy what I've worked out wrong, to introduce something different and disruptive. I'm often astonished to find how much better chance is than I am.

Form is all we have to help us cope with fundamentally chaotic facts and assaults. Formulating something is a great start. I trust form, trust my feeling or capacity to find the right form for something. Even if that is only by being well organized. That too is form.

There is sorrow, but I hope one can see that it is sorrow for the people who died so young and so crazy, for nothing. I have respect for them, but also for their wishes, or for the power of their wishes. Because they tried to change the stupid things in the world.

The political topicality of my October paintings means almost nothing to me, but in many reviews it is the first or only thing that arouses interest, and the response to the pictures varies according to current political circumstance. I find this rather a distraction.

Now there are no priests or philosophers left, artists are the most important people in the world.

Contact with like-minded painters - a group means a great deal to me: nothing comes in isolation. We have worked out our ideas largely by talking them through. Shutting myself away in the country, for instance, would do nothing for me. One depends on one's surroundings. And so the exchange with other artists - and especially the collaboration with Lueg and Polke - matters a lot to me: it is part of the input that I need.
