Paul Krugman recently did a Five Books interview with The Browser, talking about his five favorite books. The books are: Asimov’s Foundation series, Hume’s An Enquiry Concerning Human Understanding, two books by Lord Keynes, and a book of essays by economist James Tobin, one of Krugman’s old teachers. Of Foundation he says:
This is a very unusual set of novels from Isaac Asimov, but a classic. It’s not about gadgets. Although it’s supposed to be about a galactic civilisation, the technology is virtually invisible and it’s not about space battles or anything like that. The story is about these people, psychohistorians, who are mathematical social scientists and have a theory about how society works. The theory tells them that the galactic empire is failing, and they then use that knowledge to save civilisation. It’s a great image. I was probably 16 when I read it and I thought, “I want to be one of those guys!” Unfortunately we don’t have anything like that and economics is the closest I could get.
