Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody.

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.

poverty has no causes. Only prosperity has causes. Analogically, heat is a result of active processes; it has causes. But cold is not the result of any processes; it is only the absence of heat. Just so, the great cold of poverty and economic stagnation is merely the absence of economic development.

Credentialing, not education, has become the primary business of North American universities.

Unity, like so many good things, is good only in moderation.

Lots of things are not possible for municipalities, suburbs, or collections of them now. They are not possible and they would become possible, because they would have more authority. They would have the same authority as a province now.

The more successfully a city mingles everyday diversity of uses and users in its everyday streets, the more successfully, casually (and economically) its people thereby enliven and support well-located parks that can thus give back grace and delight to their neighborhoods instead of vacuity.
