I thought of one of Dan's Slog obsessions when I watched this TED Talk the other night. It argues a few things: 1) There's no politics without moral judgment. 2) Moral judgment is an evolutionary adaptation. 3) What makes a person "liberal" or "conservative" has more to do with that person's particular form of evolutionary hard-wiring than with what we normally call morality.

Which means, if true and taken to an extreme, that there's really no Morality at all, never mind where it comes from. There's just moral psychology.
