There's a legal term for a problem in public space: something that might draw people to an area-say, across train tracks-where they might be caused harm. It's called a 'public nuisance.' I wouldn't mind being called that for my life's work.

When a building is so complete within itself, I always think, "Why do I even have to go inside it?" I would love to do architecture that people can have a free hand in the making of it. We've done spaces where things are hinged and they can go out or in, but that's not freedom. That's supermarket freedom, or the notion that you can have anything you want as long as the supermarket carries it. We would love to do a space where you go inside and there's nothing there. You might have a seat and when you don't need it anymore you get up and it disappears.

Yeah, it's not that I wanted to do a painting, I wanted to do writing like that. What jolted me about Jasper Johns was how important it is to start with a convention, how important it is to start with what everybody knows and everybody takes for granted, whether it's a number, an alphabet letter, a set of alphabet letters, a target.

I wanted to be involved with the making of some kind of parallel world. I thought, there's no reason to go to different parts of our world, because you can write them. You can stay home, stay in a little room, and imagine all these worlds. And I wanted to do that. Why did I want to do that, I'm not sure if I can tell.

I came from the time of so-called New Criticism - the poem in itself, the writing in itself - but around that time I had come across a critic called Kenneth Burke, who wrote a book called A Rhetoric of Motives, and it seemed to talk about another way, and gradually I realized that other way was that the reader made a difference.

If something's public then it seems like the important thing is the person in that public. And the notion of rhetoric. I went to Jesuit schools that focused on first there's grammar, then there's rhetoric, and rhetoric's usually seen as a kind of degraded method, because you're trying to persuade.

What connects architecture and music is that neither one is really an object. It's more like an ambience, a surrounding and a context. You can do other things while you're listening to music and of course, you can do other things while you're in the middle of architecture. The notion of multi-attention seems to me like it's the keynote to the beginning of the 21st century.
