Editing Metaethics (section)

==== Error theory ====
[[Error theory]], another form of moral anti-realism, holds that although ethical claims do express propositions, all such propositions are false. Thus, both the statement "Murder is morally wrong" and the statement "Murder is morally permissible" are false, according to error theory. [[J. L. Mackie]] is probably the best-known proponent of this view. Since error theory denies that there are moral truths, error theory entails [[moral nihilism]] and, thus, [[moral skepticism]]; however, neither moral nihilism nor moral skepticism conversely entail error theory.
