When museums are left with so little money that their future is in the hands of private donors, then they are unable to develop their own signatures by collecting themselves. On the other hand, though, I think we should also celebrate the fact that there is a lot of art that lives outside of, or on the outskirts of, the art market - and it is doing quite well.

In the past Berlin was much more radical and extreme and now it's becoming much more of a conventional European city.

There are 1.3 billion people today who have no access to electricity. Many of them rely on kerosene lanterns for light, but kerosene is both expensive and hazardous to the health.

I do not think making art alone makes it any better than making it with a team of people.

Over the years, in making art, I have constantly explored issues dealing with space, time, light, and society. I am particularly interested in how the light of a space determines how we see that space and similarly, in how light and color are actually phenomena within us, within our own eyes.

For the sake of sanity, the brain and the eyes keep things simple. But take away the sense of sight and suddenly things are not so simple.

I see the artist as a participant, a co-producer of reality.
