New Urbanism: A new kind of city where people walk, rather than rely on cars, which have so long been a symbol of egoism that I believe it will be hard to have them quit their addiction. I'm not sure how much a planned city will be popular, because the best dynamism, I think, is when a great city is built in the "nexus" between absolute regulation and capitalist incoherence.

Ephemeral City: "In the past, achievement in the arts grew in the wake of economic or political dynamism. Athens first emerged as a great bustling mercantile center and military power before it astounded the world in other fields. The extraordinary cultural production of other great cities—Alexandria, Venice, Amsterdam, London, New York—rested upon similar nexuses between the aesthetic and the mundane."

San Francisco, New York, and Chicago rebuild their cities for the restless youth, the idle rich, and the bohemians, but they cannot sustain themselves as long as the standards of living grow higher than the income of the middle-class, therefore driving them away. In sum, it's a very beautiful language.
