Not TV or illegal drugs but the automobile has been the chief destroyer of American communities.

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.

You don't get new products and services out of sameness.

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.

There were lots of programs over the course of the two referendums and the general tenor of them was that if Quebec were to separate, then Canada would disintegrate.

Dull, inert cities, it is true, do contain the seeds of their own destruction and little else. But lively, diverse, intense cities contain the seeds of their own regeneration, with energy enough to carry over for problems and needs outside themselves.

Does anyone suppose that, in real life, answers to any of the great questions that worry us today are going to come out of homogeneous settlements?
