The church was always very adept at incorporating all the different artistic disciplines. What we call the church is actually an assemblage of different artistic forms, whether in its Biblical literature, or sculpture, painting, music.

I've always hated the word spirituality, but now I accept the word, and I think it's a useful term. It just means so many things. And actually, most of the things it does connote are beautiful things.

Even after seeing so much bad art in the last few years, it still seems possible that one can be led to the right places. I haven't given up hope because there are always great artists, great minds, and great ideas. New ideas are what give you hope. You have to base your opinions on the quality of the ideas in the artworks.

Museums have traditionally been places that protect the art object. But in the last 40 years, a new type of museum has emerged - the Kunsthalle or alternative space which only presents temporary, contemporary shows. Yet art is not just about the future - it is about the future and the present, but it also can't forget the past.

I've always been leery of comical artists because I think oftentimes they're hiding the fact that they're not that talented. For example, with Martin Kippenberger, I always thought he was a kind of poor man's Sigmar Polke - also a humorist - but Kippenberger used humor to get away with things he couldn't master.

I think what happened in the last 10 or 15 years in the art market is that all the players - and that includes artists, dealers, art advisors, everyone - basically became dealers. We've had old-school collectors morph into speculators, flipping works. We've seen auction houses buying works directly from artists or from sleazy middlemen. The last step before the crash was the artists themselves supplying the auction houses. Dealing themselves, you know? The art world is as unregulated as any financial market there is.

I would say that most serious artists have a pretty complete idea of what they're going to do before they do it.
