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.

It is a danger to wait around for an idea to occur to you. You have to find the idea.

Art is the pure realization of religious feeling, capacity for faith, longing for God. ... The ability to believe is our outstanding quality, and only art adequately translates it into reality. But when we assuage our need for faith with an ideology we court disaster.

Architecture was, or is, a kind of hobby, an inclination I have to fiddling around and building things. Putting up shelves or cupboards, or making tools, or designing houses ... it always has a functional or social motivation. If social changes are in the air, I am gripped immediately by the desire to build, and I think that I accelerate or anticipate changes in my life by doing so, at least in draft. In the case of my house, that was anticipation: in other words, first build, then change one's life.

I want pictorial content without sentiment, but I want it as human as possible

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

And then the work bears a strong sense of leave-taking for me personally. It ends the work I began in the 1960s (paintings from black-and-white photographs), with a compressed summation that precludes any possible continuation. And so it is a leave-taking from thoughts and feelings of my own on a very basic level. Not that this is a deliberate act, of course; it is a quasi-automatic sequence of disintegration and reformation which I can perceive, as always, only in retrospect.
