Moral epistemology

Meta-ethics is the branch of ethics that seeks to understand the nature of ethical properties, statements, attitudes, and judgments. Meta-ethics is one of the four branches of ethics generally recognized by philosophers, the others being descriptive ethics, normative ethics and applied ethics.

While normative ethics addresses such questions as "What should I do?", thus endorsing some ethical evaluations and rejecting others, meta-ethics 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 actual moral theories and for making practical moral decisions; others reason from opposite premises and suggest that we must impart ideas of moral intuition onto proper action before we can give a proper account of morality's metaphysics.

According to Richard Garner and Bernard Rosen, there are three kinds of meta-ethical problems, or three general questions:

A question of the first type might be, "What do the words 'good', 'bad', 'right' and 'wrong' mean?" (see value theory). The second category includes questions of whether moral judgments are universal or relative, of one kind or many kinds, etc. Questions of the third kind ask, for example, how we can know if something is right or wrong, if at all. Garner and Rosen say that answers to the three basic questions "are not unrelated, and sometimes an answer to one will strongly suggest, or perhaps even entail, an answer to another."

A meta-ethical theory, unlike a normative ethical theory, does not attempt to evaluate specific choices as being better, worse, good, bad, or evil; although it may have profound implications as to the validity and meaning of normative ethical claims. An answer to any of the three example questions above would not itself be a normative ethical statement.

These theories mainly put forward a position on the first of the three questions above, "What is the meaning of moral terms or judgments?" They may however imply or even entail answers to the other two questions as well.
