About: Moral supervenience

The principle of moral supervenience states that moral predicates (e.g., permissible, obligatory, forbidden, etc.) supervene upon non-moral predicates, and hence that moral facts involving these predicates (like stealing is wrong) 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. The principle is sometimes qualified to say that moral facts supervene upon natural facts, i.e., observable, empirical facts within space-time, but a broader conception could allow the supervenience base to include any non-moral facts, including (if there are any) non-natural facts (e.g., divine commands, Platonic truths).
