There is no new world that you make without the old world.

Whenever and wherever societies have flourished and prospered rather than stagnated and decayed, creative and workable cities have been at the core of the phenomenon. Decaying cities, declining economies, and mounting social troubles travel together. The combination is not coincidental.

My husband was a hospital architect and he was working on some hospitals in Alberta, and I told him to try to find out what they thought about separatism. He would come back on weekends. He said "well, I think I found out how they feel about separatism. I brought it up at lunch in the cafeteria, and everybody at the table was silent and then somebody said 'Let's change the subject'."

Everybody's got a worldview, whether they know they have it or they don't. They might even get it when they are little tiny kids. Suppose they get it when they are in college, which is often the case, or in high school, whatever. Everything they learn after that or every thing they see after that, they fit it into that worldview. And they are making coherence of what's good, what's bad, what will work, what won't work, what's noble, what's ignoble, and so on... all through this filter.

observation of realities has never, to put it mildly, been one of the strengths of economic development theory.

But look what we have built low-income projects that become worse centers of delinquency, vandalism and general social hopelessness than the slums they were supposed to replace. Cultural centers that are unable to support a good bookstore. Civic centers that are avoided by everyone but bums. Promenades that go from no place to nowhere and have no promenaders. Expressways that eviscerate great cities. This is not the rebuilding of cities. This is the sacking of cities.

New ideas often need old buildings.
