Never underestimate the power of a city to regenerate.

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.

In our American cities, we need all kinds of diversity.

I basically don't think that the way we do things is that dependent on one resource, such as oil. There can be different kinds of engines for cars. I think that solar heating, wind heating can substitute for a lot of uses for oil. I'd like to see those things happen because they are more sustainable in any case. But I do not think that running out of oil is not going to bother us that much. I think we have got to be rescued by something or we really are going down a slippery slope.

I have been dwelling upon downtowns. This is not because mixtures of primary uses are unneeded elsewhere in cities. On the contrary they are needed, and the success of mixtures downtown (on in the most intensive portions of cities, whatever they are called) is related to the mixture possible in other part of cities.

Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody.

Why did I become a Canadian citizen? Not because I was rejecting being a U.S. citizen. At the time when I became a Canadian citizen, you couldn't be a dual citizen. Now you can. So I had to be one or the other. But the reason I became a Canadian citizen was because it simply seemed so abnormal to me not to be able to vote.
