Septuagenarian Lewis Lapham's post-Harper's magazine Lapham's Quarterly finally launched last night after a prolonged gestation period. Carnegie Corporation president Vartan Gregorian, who made an appearance in Lapham's "dramatic documentary musical" called The American Ruling Class, did introductions. Lapham, as Lapham does, didn't wear socks. Portfolio's Jeff Bercovici says the "Lapham's Quarterly will change the way you think about thinking." Of course he, like almost everyone else, hadn't actually read the issue.
