I basically don't think that the way we do things is that dependent on one resource, such as oil. There can be different kinds of engines for cars. I think that solar heating, wind heating can substitute for a lot of uses for oil. I'd like to see those things happen because they are more sustainable in any case. But I do not think that running out of oil is not going to bother us that much. I think we have got to be rescued by something or we really are going down a slippery slope.

As in the pseudoscience of bloodletting, just so in the pseudoscience of city rebuilding and planning, years of learning and a plethora of subtle and complicated dogma have arisen on a foundation of nonsense.

Designing a dream city is easy; rebuilding a living one takes imagination.

All through organized history, if you wanted prosperity you had to have cities. Cities are places that attract new people with new ideas.

The primary conflict, I think, is between people whose interests are with already well-established economic activities, and those whose interests are with the emergence of new economic activities.

Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.

Dull, inert cities, it is true, do contain the seeds of their own destruction and little else. But lively, diverse, intense cities contain the seeds of their own regeneration, with energy enough to carry over for problems and needs outside themselves.
