 [This entry uses the label “non-objectivism” instead of the simple “subjectivism” since there is an entrenched usage in metaethics for using the latter to denote the thesis that in making a moral judgment one is reporting (as opposed to expressing) one’s own mental attitudes (e.g., “Stealing is morally wrong” means “I disapprove of stealing”). So understood, subjectivism is a kind of non-objectivist theory, but there are many other kinds of non-objectivist theory, too.]
