It would be wrong to say that the city of Berlin is not regulated. What I think is more interesting is to what extent a city creates a sort of safe haven for its users, so that people feel confident that the city works on their behalf.

Light has an evident, functional and aesthetic impact on our lives.

Having an experience is taking part in the world. Taking part in the world is really about sharing responsibility.

In many rural areas of the world, local communities use kerosene for indoor lighting, which leads to asthma, poor quality of light, and the desperate cycle of oil-based products that continually degrade the environment.

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

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.

I see the artist as a participant, a co-producer of reality. I do not see the artist as a person who sits at a distance and evaluates.
