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.

There are two ways you encounter things in the world that are different. One is everything that comes in reinforces what you already believe and everything that you know. The other thing is that you stay flexible enough or curious enough and maybe unsure of yourself enough, or may be you are more sure of yourself - I don't know which it is - that the new things that come in keep reforming your world view.

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

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