I just heard the two candidates speak at the Alfred Smith annual dinner, where notables (and the two presidential candidates) are expected to deliver humorous, self-deprecating speeches. Both were funny, but I sensed an overflow of bile in Obama’s contribution to the evening. McCain’s by contrast was funny and gracious (with a couple barbs). The evening’s remarks reinforced why Aristotle made wittiness literally his ultimate moral virtue.
Some representative quotes here.
