Is Mackie a moral anti realist?

Essentially, Mackie argues that the moral realist is correct about morality conceptually speaking—we are moral realists—but the moral realist is incorrect about how the world actually is. Moral facts place demands upon us, but (Mackie asks) how could such demands exist objectively?

How is moral disagreement a problem for realism?

Others beg the question against the moral realist, and yet others raise serious objections to realism, but ones that – when carefully stated – can be seen not to be essentially related to moral disagreement.

Is ethical supervenience a problem for the realist?

Given that Moore and Sidgwick were both ethical realists, it is perhaps striking that the most influential philosophical use of ethical supervenience has been in arguments against ethical realism.

What does the principle of moral supervenience state?

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.
