You know, Darwin said through natural selection things go gradually, and he was talking about pigeon's evolution or horses evolving, getting faster. But in fact if you look at evolution on a bigger scale, cosmic evolution and you look at culture evolution you see it jumps, it goes through phase changes, and that's very exciting.

But I do believe architecture, and all art, should be content-driven. It should have something to say beyond the sensational.

What is the most interesting thing to people? Other people.

I've been a lucky man. I've only faced one real tragedy: the death of my wife, Maggie, from cancer in 1995.

Beautiful people are always with us, as evolutionary psychologists and a trip to the news-stand confirm.

I'd been to Stourhead and was inspired by the perfect parity between architecture and art; in fact, the architecture is the art. I wrote a piece called 'Not Sculpture Park,' because most of these things become car parks for bought-in sculpture. The artists should be working with the site, not just plonking pieces down.
