The question of whether moral facts exist independently of human beliefs and preferences is central to metaethics. Moral realists argue that some claims like 'torturing children for amusement is wrong' are objectively true, not merely opinions. Anti-realists deny objective moral facts but disagree about what moral language really does—express emotions, prescribe action, or construct meaning relative to perspective.
Examine cases where moral agreement seems universal (harm to innocent) versus cases of persistent disagreement (priority of liberty versus equality) to test realist intuitions against skepticism about objectivity.
Denying objective moral facts doesn't commit you to nihilism or the view that anything goes; many anti-realists defend rigorous, rationally compelling moral standards. Also, agreement alone doesn't establish objectivity—widespread false belief is possible.
You've distinguished normative from metaethical questions. This topic is firmly metaethical: not "what should we do?" but "what kind of thing are moral claims?" When someone says "torturing children for amusement is wrong," are they stating an objective fact that exists independently of human attitudes — like the fact that water is H₂O — or are they doing something else: expressing an attitude, prescribing behavior, or constructing a norm relative to their community? This is the central debate between moral realism and moral anti-realism.
Moral realists hold that there are mind-independent moral facts: truths about what is right or wrong that are not made true by anyone's beliefs, preferences, or social practices. Just as "the Earth is roughly spherical" would be true even if everyone believed it was flat, realists claim "gratuitous cruelty is wrong" is true even if every human believed otherwise. Realism comes in multiple varieties. Non-naturalists (like G.E. Moore) hold that moral properties are real but not reducible to natural properties like pleasure or evolutionary fitness. Naturalists (like Peter Railton) hold that moral facts are real and can be identified with natural facts — "good" means something like "what promotes flourishing." The challenge for realism is epistemological: if moral facts are objective features of reality, how do we access them? We can't observe wrongness through a microscope.
Moral anti-realists deny that there are mind-independent moral facts but disagree about what moral language is doing instead. Expressivists (Hare, Blackburn, Gibbard) say moral statements don't assert facts at all — "gratuitous cruelty is wrong" expresses disapproval or commits the speaker to a norm, rather than describing a state of affairs. Error theorists (Mackie) take a harder line: moral statements do try to assert facts, but those facts don't exist, so all positive moral claims are systematically false. Constructivists (Korsgaard, Rawls) stake out a middle ground: moral facts are constructed through rational procedures or the conditions of agency, making them objective in a procedural sense without requiring mind-independent moral properties in nature.
The debate has practical implications that are easy to miss. If anti-realism is true, cross-cultural moral disagreement is not surprising — it may reflect different constructions or different expressions of attitude, not different responses to the same moral fact. If realism is true, persistent disagreement becomes harder to explain: why do rational people, looking at the same moral reality, persistently disagree about it? One influential realist response is that moral perception, like perceptual experience, can be distorted by bias, limited perspective, or self-interest — moral disagreement is like disagreement about contested empirical questions rather than like disagreement about mathematics. The sophistication of the debate lies in seeing that both sides have genuine resources: anti-realists can defend rigorous moral standards without facts, and realists can explain disagreement without abandoning objectivity. Neither position entails that morality is arbitrary or that it cannot be reasoned about.
