Intricate minglings of different uses in cities are not a form of chaos. On the contrary, they represent a complex and highly developed form of order.

Streets and their sidewalks-the main public places of a city-are its most vital organs.

Everyone is aware that tremendous numbers of people concentrate in city downtowns and that, if they did not, there would be no downtown to amount to anything--certainly not one with much downtown diversity.

I think it is fatal to specialize. And all kinds of things show us that and that the more diverse we are in what we can do, the better.

There are still an awful lot of intelligent, clever constructive Americans and they are still doing clever constructive things.

observation of realities has never, to put it mildly, been one of the strengths of economic development theory.

Reformers have long observed city people loitering on busy corners, hanging around in candy stores and bars and drinking soda popon stoops, and have passed a judgment, the gist of which is: "This is deplorable! If these people had decent homes and a more private or bosky outdoor place, they wouldn't be on the street!" That judgment represents a profound misunderstanding of cities. It makes no more sense than to drop in at a testimonial banquet in a hotel and conclude that if these people had wives who could cook, they would give their parties at home.
