 Metaethics is the branch of ethics that seeks to understand the nature of ethical properties, statements, attitudes, and judgments. Metaethics is one of the three branches of ethics generally studied by philosophers, the others being normative ethics and applied ethics. While normative ethics addresses such questions as what should I do? Thus endorsing some ethical evaluations and rejecting others, Metaethics addresses questions such as what is goodness? And how can we tell what is good from what is bad? Seeking to understand the nature of ethical properties and evaluations. Some theorists argue that a metaphysical account of morality is necessary for the proper evaluation of actually moral theories and for making practical moral decisions. Others reason from opposite premises and suggest that studying moral judgments about proper actions can guide us to a true account of the nature of morality.
