I was told visionary architect Paolo Soleri had stopped giving interviews. But we got one. At Arcosanti, during a weekly talk to young architects from all over the world, he spoke about the huge waste of energy in urban sprawl and why mixed-use planning is needed. We were served frugal soup. The man has made perfect sense for some 50 years. Has he gotten credit? Not that I know of. Add portfolios by Bella Feldman and James Doolin. Kathleen Cramer's "A Tour with Heidegger." And we talk with Montreal architect and friend of Ivan Illich, Terrence Galvin, about "The Meaning of Proportion." What is it to dwell? To living-exist?
