Moral supervenience

The principle of moral supervenience states that moral predicates supervene upon non-moral predicates, and hence that moral facts involving these predicates supervene upon non-moral facts. The moral facts are hence said to be supervenient facts, and the non-moral facts the supervenience base of the former. Moral facts could be about actions, character traits, or situations, e.g., stealing is wrong, Alice is virtuous, or Shane's suffering was morally bad.
