Architecture is art. I don't think you should say that too much, but it is art. I mean, architecture is many, many things. Architecture is science, is technology, is geography, is typography, is anthropology, is sociology, is art, is history. You know all this comes together. Architecture is a kind of bouillabaisse, an incredible bouillabaisse. And, by the way, architecture is also a very polluted art in the sense that it's polluted by life, and by the complexity of things.
