Moral Realism

Moral realism is the metaethical position that moral claims are truth-apt — they can be true or false — and that some moral claims are true independently of anyone's beliefs, desires, or cultural commitments. It stands in opposition to moral anti-realism, which holds that moral claims express attitudes, prescriptions, or social constructions rather than facts about the world.

The central challenge for moral realism is to explain what kind of facts moral facts are and how we could come to know them. Naturalistic moral realism identifies moral facts with natural facts: the claim that suffering is bad is true because suffering is a natural state that rational agents have reason to avoid. Non-naturalistic realism, associated with G.E. Moore, holds that moral facts are sui generis — irreducible to natural or supernatural facts — and knowable through intuition. Both versions face epistemological difficulties: naturalistic realism risks collapsing moral facts into descriptive facts and losing normative force; non-naturalistic realism struggles to explain how humans could have epistemic access to non-natural properties.

From a systems perspective, moral realism can be reframed as the claim that certain system configurations are genuinely better than others — not merely better for some observer but better in terms of the system's capacity to maintain and elaborate its own organization. On this view, moral facts are not transcendent truths but emergent constraints on the dynamics of self-organizing systems. The claim that cruelty is wrong is the claim that cruelty destabilizes the social systems that make cooperation possible, and that this destabilization is not a matter of opinion but a dynamical consequence of the system's structure.
