The space program caused so much future-thinking in culture. People who couldn't go to the Moon were building space-fantasy chairs and corsets and hairdos and anything that they could put their hands on.

I wouldn't say the anthropologists were making art, but they were definitely justifying their practices with very personal reasoning, passion, and they were also experimenting with form. There was a sense of trying to be as sincere as possible, whether you were investigating something far away from you or very close.

National parks, zoos, protected areas, polluted seas - using the whole world as a readymade, I thought about it as a stage set. To activate a stage set you need a drama, an actor to offset it.

I'm neither shy nor impressed by media and press. It's just another industry to me. My response to the criticism was, "I work with a steel factory. Why can't I work with the media?"

Of course, I'd welcome protest. Good criticism is hard to find.

The Stonehenge proposal got a lot of interesting criticism. One of the best - or worst - said something like, "Go home to Las Vegas." I think this project could possibly be realized at a very late part of my career. Right now, I don't have the authority, the budget, the credibility.

My purpose isn't to be confrontational. My purpose is to find out about the world and play myself against it to the extent that it is even conceivable.
