The public realm in America has two roles: it is the dwelling place of our civilization and our civic life, and it is the physical manifestation of the common good. When you degrade the public realm, you will automatically degrade the quality of your civic life and the character of all the enactments of your public life and communal life that take place there.

Government at all levels in the USA right now is engaged in a quixotic campaign to sustain the unsustainable. We're determined to run WalMart, Disney World, the Interstate Highways, suburbia, and an imperial military by other means than oil. We'll squander a lot of dwindling resources in the process.

The economy of the 21st century will come to center on agriculture. Life will be intensely and profoundly local in ways that we can't conceive of today. Economic growth, as we have known it in a cheap energy industrial paradigm, will cease.

For instance, the most common type of "affordable housing" in the world comes in the form of apartments over stores.

Most of suburbia will end up in three ways: ruins, slums, salvage yards for materials.

The ideas of [ Le Corbusier ] that actually found their way into practice were deeply destructive - for instance, the tower-in-a-park, which mutated into the vertical slums of the late 20th century.

My beef with the alt-fuel people is not the renewable or alt-fuel ideas themselves. Sooner or later, there's no question we're going to have to rely on them. For me, it's an issue of scale.
