Purpose is not necessary to make a building beautiful.

How does an artist know when the line that he just painted is good or not good? That's the catch. De Kooning was the greatest of my contemporaries in art, and he knew when he'd done a good line. When he didn't, he threw it away. I wish I'd thrown away some of mine.

I like to be buttoned onto tradition. The thing is to improve it, twist it and mold it; to make something new of it; not to deny it. The riches of history can be plucked at any point.

The practice of architecture is the most delightful of all pursuits. Also, next to agriculture, it is the most necessary to man. One must eat, one must have shelter. Next to religious worship itself, it is the spiritual handmaiden of our deepest convictions.

In my own work, I'd say I'm a classicist, but I look everywhere for my solutions. I don't study the toilet-living habits of my clients, although that's a popular approach. First, I think of every building in history that has been similar in purpose. Then I think of the functional program - that's a major part of the study.

To me, the drive for monumentality is as inbred as the desire for food and sex, regardless of how we denigrate it. Monuments differ in different periods. Each age has its own.

I get between nine and ten hours of sleep. Go to bed at 8:30 and get up at 6:00 or 6:30 if I oversleep.
