Many take the claim that you cannot ‘get’ an ‘ought’ from an ‘is’ to imply that non-moral beliefs are by themselves incapable of justifying moral beliefs. I argue that this is a mistake and that the position that moral beliefs are justified exclusively by non-moral beliefs—a view that I call moral inferentialism—presents an attractive non-sceptical moral epistemology.
