Moral realism is the meta-ethical view which claims that:
- Ethical sentences express propositions.
- Some such propositions are true.
- Those propositions are made true by objective features of the world, independent of subjective opinion.
This makes moral realism a non-nihilist form of cognitivism. Moral realism stands in opposition to all forms of moral anti-realism, including ethical subjectivism (which denies that moral propositions refer to objective facts), error theory (which denies that any moral propositions are true), and non-cognitivism (which denies that moral sentences express propositions at all). Within moral realism, the two main subdivisions are ethical naturalism and ethical non-naturalism.
- Moral absolutism
- Moral relativism
- Moral skepticism
