Not content, but the road the artist takes, is the interesting part.

Art is difficult. Its not entertainment.

I was interested in transcendence from a very early age. I was interested in what was over there, what was behind life. So when I had my first communion I was very disappointed. I had expected something amazing and surprising and spiritual. Instead all I got was a bicycle. That wasn't what I was after at all.

Art maybe the only space where an indvidual can be utterly free to question himself, as well as his relationship to his God

When, at the end of the 1960s, I became interested in the Nazi era, it was a taboo subject in Germany. No one spoke about it anymore, no more in my house than anywhere else.

As a child I had no toys; our house was bombed, but there were lots of bricks. Ruins are wonderful because they are the beginning of something new, you can do something with them.

I believe art has to take responsibility but it should not give up being art.
