Suppose the moral facts depend on the attitudes or opinions of a particular group or individual (e.g., “X is good” means “Caesar approves of X,” or “The Supreme Court rules in favor of X,” etc.), and thus moral truth is an entirely mind-dependent affair. Since, in this case, all speakers' moral utterances are made true or false by the same mental activity, then this is not strictly speaking a version of relativism, but is, rather, a relation-designating account of moral terms (see Stevenson 1963: 74 for this distinction)."

Moral relativism is sometimes thought of as a version of anti-realism, but (short of stipulating usage) there is no basis for this classification; it is better to say that some versions of relativism may be anti-realist and others may be realist."

"A subjectivist ethical theorist is a theory according to which moral judgements about men or their actions are judgements about the way people react to these men and actions - that is, the way they think or feel about them."

"No single description is likely to capture all realist views, but a reasonably accurate rule is to understand moral realism as the conjunction of three theses: The semantic thesis: The primary semantic role of moral predicates (such as "right" and "wrong") is to refer to moral properties (such as rightness and wrongness), so that moral statements (such as "honesty is good" and "slavery is unjust") purport to represent moral facts, and express propositions that are true or false (or approximately true, largely false and so on). The alethic thesis: Some moral propositions are in fact true. The metaphysical thesis: Moral propositions are true when actions and other objects of moral assessment have the relevant moral properties (so that the relevant moral facts obtain), where these facts and properties are robust: their metaphysical status, whatever it is, is not relevantly different from that of (certain types of ordinary non-moral facts and properties)."
