Metaethics is a branch of moral philosophy that examines the nature, meaning, and foundations of ethical concepts and judgments. Unlike normative ethics, which asks what actions are right or wrong, or applied ethics, which addresses specific moral issues, metaethics investigates deeper questions such as: What does “good” mean? Are moral values objective or subjective? Can moral claims be true or false? Through these inquiries, metaethics seeks to clarify the logical structure, epistemological status, and metaphysical grounding of moral discourse. The major branches of metaethics include moral realism and anti-realism, cognitivism and non-cognitivism, naturalism and non-naturalism, subjectivism and objectivism, and moral skepticism. One of the central branches of metaethics is the debate between moral realism and moral anti-realism. Moral realism holds that moral facts or truths exist independently of human beliefs, feelings, or attitudes. According to this view, statements such as “honesty is good” or “cruelty is wrong” are true or false in virtue of objective moral facts. Realists argue that moral properties are part of the fabric of reality, and ethical statements aim to describe these properties. In contrast, moral anti-realism denies the existence of such objective moral facts. Anti-realists maintain that moral values are not independent features of the world but are instead constructed by individuals or societies. This debate addresses the ontological status of morality and raises questions about whether ethical truths are discovered or created. Closely related to realism and anti-realism is the distinction between cognitivism and non-cognitivism. Cognitivism asserts that moral statements are propositions that can be true or false. When someone says, “Stealing is wrong,” a cognitivist interprets this as expressing a belief about a moral fact. Cognitivism is often associated with moral realism, though it can also be compatible with some forms of anti-realism. Non-cognitivism, on the other hand, claims that moral statements do not express beliefs but rather emotions, prescriptions, or attitudes. According to this view, saying “Stealing is wrong” may simply express disapproval or function as a command, similar to saying “Do not steal!” Non-cognitivist theories include emotivism,
