EY has commented that his MetaEthics sequence is one of his least successful. Can anyone else do better? The 'official' ethical position here seems to be a kind of utilitarianism, but we ought (for some values of 'ought') to also know something about competing approaches to ethics, including deontological ethics, virtue ethics, and naturalistic ethics (Nozick, Gauthier, and Binmore, for example).

We have deontological ethics covered. At least one post by Alicorn and the actual direct moral assertions around here are usually significantly deontological in nature.
