A region is an area safely larger than the last one to whose problems we found no solution.

But look what we have built low-income projects that become worse centers of delinquency, vandalism and general social hopelessness than the slums they were supposed to replace. Cultural centers that are unable to support a good bookstore. Civic centers that are avoided by everyone but bums. Promenades that go from no place to nowhere and have no promenaders. Expressways that eviscerate great cities. This is not the rebuilding of cities. This is the sacking of cities.

Cities never flourish alone. They have to be trading with other cities. My new hypothesis shows why. But also in trading with each other they can't be in too different stages of development, and they can't copy one another.

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.

Cities never flourish alone. They have to be trading with other cities.

The notion - and I tell you this one even worries me that it extends into New Urbanism - the notion of the shopping center [as] a valid kind of downtown. That's taken over. It's very hard for architects of this generation even to think in terms of a downtown or a center that is owned by all different people, with different ideas.

Expanding the Toronto Island Airport will undermine the downtown's economy and liveability and intensify pollution and smog from Oshawa to Oakville. I urge Torontonians to close down this dangerous Trojan horse and get on with planning constructive and delightful ways of using our magnificent lakeside assets.
