I think the role of artists in the past was very different. Artists had less responsibility in many ways.

The public is in need of experiences that are not just voyeuristic. Our society is in a mess of losing its spiritual centre.

I'm talking about intellectually and emotionally challenging, but at the same time it's actually not that challenging. So there's this dichotomy.

I just want to create situations where people forget time.

From the very early stage when I started doing performance art in the '70s, the general attitude - not just me, but also my colleagues - was that there should not be any documentation, that the performance itself is artwork and there should be no documentation.

Performance has to be mainstream art. This is what I'm fighting for.

I say we don't need art in nature, because it's so perfect without us. We need it in the cities. But the cities have absolutely lost their own center. They think having ten cars and a big bridge is the way to happiness. It's not.
