I still have a lot of family in America. I still have a lot of friends there. There is a lot that I admire there very much. When I find America getting too much criticized outside America, I want to tell them how many things are good about it.

There is no logic that can be superimposed on the city; people make it, and it is to them, not buildings, that we must fit our plans.

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.

Reactions [on my 1979 Massey lectures] were from Anglophones. I'm one. But I'm terrible at French. In fact, there was practically no reaction.

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.

The first fundamental of successful city life: People must take a modicum of responsibility for each other even if they have no ties to each other. This is a lesson no one learns by being told. It is learned from the experience of having other people without ties of kinship or close friendship or formal responsibility to you take a modicum of responsibility for you.
