I'm not saying the 1970s was a golden age - I don't believe such a thing exists in art . . . It would be like talking about a golden age of science. But it's true that those were slightly more ideological times, and the relevance of artists wasn't established by their CVs but by their work.

My ideas are all the same but look different.

It's in our nature. If you are a plumber, there is an objective way to establish whether you put together a great piping system or not. Art is a bit more slippery than that. So, when you fill a gallery with dirt and someone comes along waving wads of bills, it's difficult not to take them because they become a tangible acknowledgement that what you've been doing actually makes sense.

I don't design. I don't paint. I absolutely never touch my works.

I do not know exactly why, but it seems to me that images do not belong to anybody but are instead there, at the disposal of all.

I tend not to work with a specific person in mind. Art is a matter of statistics. It's not about individuals. It's about people.

I'm criticizing the way they are perceived. I was going through a book of Marina Abramovic and Ulay's 1970s performance work the other day. These people did two, even three Documentas or Venice Biennales over the course of a decade without any fuss. They would just treat it as any of their other engagements, with the same level of dignity and commitment they'd reserve for a one-day event in a small gallery on the Austrian mountains.
