I am very generous with my dealers in terms of the art that they have of mine. They all have a very good selection of work that they can work with. And it is up to them to find the dealers. I don't interfere with their selling.

But artistically, my art I kept very separate from my political beliefs, deliberately and very, very rarely would I allow that kind of thing into it.

I always had a fairly decent income, coming in just from the art.

I may have a lot of political opinions but it doesn't necessarily come into my work. I keep the two worlds separate.

How does any idea come to your mind? I don't know.

The idea of, say, the compressed space between the floor and the object hanging over it and then the long space between the object and the ceiling was a kind of interesting idea for me - the idea of compressing and expanding. That was an idea that I worked with, which you could only do sculpturally. You can't really do with a painting on the wall.

Any artwork is part of something larger, grander and, you know, the situation that it's in is very important.
