I was interested in how we engage the world. How do we use our skin as our eyes? If you read a cityscape or a landscape with just your mind, and not your body, it becomes like a picture or representation, not something you really engage with.

I myself have already spent a third of my life in Germany, first in Cologne and then, since 1994, in Berlin.

Artists are valuable to public discussion: They show the correlation between doing and thinking.

Every city is always changing, on its own trajectory.

If I have the choice of traveling to Russia, India or New Zealand alone for a week for preliminary discussions or to spend that week with my family, I routinely choose my family.

I am not opposed to the art market. I have lots of friends who are collectors. But the whole idea of the art market is complex. Sadly we have a situation where auction houses and secondary market dealers are creating a lot of confusion and unnecessary pollution.

I don't know a single collector or museum director who says: 'Oh, he's on a list, so I think I'll buy something of his.' The people who buy my art put a little more thought into it than that.
