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.

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

If you look at Gothic detailing right down to the bottom of a column or the capital of a column, it's a small version of the whole building; that's why, like dating the backbones of a dinosaur, a good historian can look at a detail of a Gothic building and tell you exactly what the rest of the building was, and infer the whole from the parts.

You have to believe in a placebo or it wont work, but if it works, its obviously working in some indirect way, through feedback in the immune system, let us say, or in the willpower of the patient to take a more strenuous exercise in their own therapy.

The cell is a city of production centres, each part working away like mad, and it's co-ordinated. Six trillion cells in a body - you can't help but be moved.
