We are Humeans about morality, for in practice morality is an aesthetic. We approve what we approve, and disapprove what we do, and if something does not look or feel right, it's wrong. Don't kid yourself about what you think--you think with you eyes most of the time. You have the possibility to be other than Humean if you notice this, but not if you do it from a theoretical perspective. You must do it from a practical perspective, from what you do rather than what you think.
