From the frontiers of science to crystals and channeling, The Fringes of Reason is devoted to the hundreds of strange and exciting beliefs flourishing in New Age America. 250 photos and illustrations. (Metaphysics/Philosophy)
A collection of articles about fringe science, metaphysics, and New Age spirituality, written in a very nice "friendly but unconvinced" style that's not too credulous but not openly hostile. At worst the author of some article may veer into gentle half-mockery, but only because the idea being discussed is so preposterous... and it is usually the idea at fault, or the person only if they are pretty clearly out to bilk the gullible.
Published in 1989, it's a nice window into the peak of the New Age movement. Plenty of citations/references, too, for more reading (both of the skeptical and the credulous variety). The overall attitude is more of a bemused "Huh, people have a lot of strange beliefs!" which I do appreciate.
Oh, and the Whole Earth Catalog website has a free web version (here: http://wholeearth.com/issue-electroni...) or a pdf version for just 2 bucks. How very nice of them!
