The future of architecture is culture.

Faith? Haven't any. I'm not a nihilist or a relativist. I don't believe in anything but change. I'm a Heraclitean - you can't step in the same river twice.

Houston is undoubtedly my showcase city. I saved all my best buildings for Houston.

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 sum up the state of architecture in America: ninety percent of the buildings we live in and around aren't architecture. No, that's not right - 98 percent.

There's no worse feeling than seeing my buildings and realizing the mistakes.

In our greatest universities, naturalism - the doctrine that nature is all there is - is the virtually unquestioned assumption that underlies not only natural science but intellectual work of all kinds.
