Last year, I reviewed Ken Goffman/RU Sirius' excellent Counterculture through the Ages for the Wash Post, calling it "an unabashed defense of Enlightenment ideas about individualism, science and material progress" (whole review here).
The book's now out in paperback, so it's cheaper than ever to pick up here.
Sirius interviewed me a while back for his webzine NeoFiles. That's online here.
And he had Reason's Tim Cavanaugh on his radio show here.
