Paul Krugman on Isaac Asimov's Foundation trilogy. I was a huge Asimov fan as a child; I loved these books, and read them at a young enough age (9? 10?) that I did not really know - I mean, I knew, but I didn't understand - that psychohistory was not a "real" discipline. I imagined that when I grew older I would be able to learn such mastery myself of the complex workings of societies and the future! I like psychogeography too but it's got nothing on the appeal of psychohistory, I think....
