On Shermer on morality

This is my critical commentary on Michael Shermer's paper "Morality is real, objective, and natural." Shermer and I agree that morality is both real and objective. Here I raise serious reservations about both Shermer's account of where morality comes from and his account of what morality tells us to do. His approach to the foundations of morality would allow some very disturbing behaviors to count as moral, and his approach to what morality says does not provide the action guidance we need from a moral theory.
