While the expression “moral relativism” means different things to different people, I offer the following characterization of it. By “moral relativism,” I understand a normative view that explains people’s incommensurable moral judgments based on their subjective preferences or on different action-guiding contexts. Moral relativists deny that value judgments can be universally justified. Therefore, for them, value judgments have neither objective universal truth-value nor universal moral import. That is, these judgments are neither true nor false, nor right or wrong for everyone. For some moral relativists even to raise the possibility of moral disagreement across different cultures or communities would be simply moot.
Moral relativists can assume a subjective or a contextual point of view. If they assume a subjective point of view, one might describe their theories or hypotheses as nihilistic. Nihilists recognize no transcendent moral values and no moral facts. According to them, predicates, such as right or wrong, or good or bad, have no independent reference. So nihilists recognize no significant moral difference between, for example, the deliberate killing of the objectively innocent, which is considered murder by most civilized people, and killing in self-defense. For them, even the principle of the presumption of innocence would be vacuous.
