Love her or hate her, you can’t deny that Ayn Rand, the 20th century’s most bellicose/eloquent (select adjective based on political persuasion) defender of laissez-faire capitalism, is experiencing a revival. Sales of her 50-year-old magnum opus, Atlas Shrugged, for years second only to the Bible, are soaring even more this year. Two major publishing houses have rushed to release new Rand biographies—by academics, no less—this fall. And there is nary a tea party protest that doesn’t prominently splash banners alluding to John Galt, Atlas Shrugged’s ubermensch hero.
