Wittgenstein and Wittgenstein and Wittgenstein

As if geniuses weren't bad enough on their own, they occur in families! And in the case of the philosopher Ludwig Wittgenstein, his was a family of (mostly) geniuses.

Who's more brilliant? Who's more neurotic? Who's the dummy of the lot? Alexander Waugh, son of the comic genius, is a promising biographer for the Wittgenstein family. His book about the whole luminous lot of 'em is reviewed in the New York Times.
