Yesterday, I posted with some fury about one of Joe Biden’s lines. He said, “These times require more than a good soldier, they require a wise leader.” I thought that was pretty disgusting. You could interpret Biden to mean, “McCain may be good enough to go off to Vietnam and get himself tortured. Good for him. But he just ain’t smart enough to be president.”

Anyway, a reader wrote in with a well-known quote from Thucydides: “The society that separates its scholars from its warriors will have its thinking done by cowards and its fighting done by fools.” I don’t know if we can go all the way with that — but ol’ T. has certainly given us something to think about.
