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

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

New ideas must use old buildings

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.

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

...frequent streets and short blocks are valuable because of the fabric of intricate cross-use that they permit among the users of a city neighbouhood.

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.
