New ideas often need old buildings.

Neighborhoods built up all at once change little physically over the years as a rule...[Residents] regret that the neighborhood has changed. Yet the fact is, physically it has changed remarkably little. People's feelings about it, rather, have changed. The neighborhood shows a strange inability to update itself, enliven itself, repair itself, or to be sought after, out of choice, by a new generation. It is dead. Actually it was dead from birth, but nobody noticed this much until the corpse began to smell.

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.

Let's see in those indictments you can't level at Sweden, they never tried to ban the constitution or undermine the settlement that they wanted. Well you can't say that of Canada. Any indication of revolt on the part of Quebec was either bought off, with a good deal of corruption.

All my life I have been hearing that the oil was going to run out. It never happens. They keep discovering new oil fields. The world is apparently floating in oil fields.

In trading with each other cities can't be in too different stages of development, and they can't copy one another. Backward cities, or younger cities, or newly forming cities in supply regions, have to develop to a great extent on one another's shoulders. This is one of the terrible things about empires. Empires want them only to trade with the empire, which doesn't help them at all. It's just a way of exploiting them.

Virtually all ideologues, of any variety, are fearful and insecure, which is why they are drawn to ideologies that promise prefabricated answers for all circumstances.
