The best part of a Reg Hartt presentation is what he has to say.

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

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.

In our American cities, we need all kinds of diversity.

Does anyone suppose that, in real life, answers to any of the great questions that worry us today are going to come out of homogeneous settlements?

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.

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.
