I try to do everything from thinking about big issues like how a building fits into the larger stream of architectural history to practical issues such as how it feels to navigate your way through its interior.

On New York subways in the 1980s: Riding on the IRT is usually a matter of serving time in one of the city's most squalid environments-noisy, smelly, crowded and overrun with a ceaseless supply of graffiti.

New York remains what it has always been : a city of ebb and flow, a city of constant shifts of population and economics, a city of virtually no rest. It is harsh, dirty, and dangerous, it is whimsical and fanciful, it is beautiful and soaring - it is not one or another of these things but all of them, all at once, and to fail to accept this paradox is to deny the reality of city existence.

Right after 9/11 it looked as if the idea of a huge skyscraper might be considered obsolete. It came back, but I think that's more closely connected to the rise of Asian and Middle Eastern cities in the world economy (Dubai, Shanghai, Taipei, etc.) than anything else.

I don't usually go in for reviews of buildings that aren't yet built, since you can tell only so much from drawings and plans, and, besides, has there ever been a building that didn't look great as a model?

Buildings don't exist to be pinned, like brooches, on the front of bigger structures to which they bear only the most distant of relationships.

For most of the nineteen-seventies, the official route map of the New York City subway system was a beautiful thing.
