A presentation of the most important classical and contemporary theories in normative and metaethics, including utilitarianism (act and rule), egoism, the categorical imperative, social contract theory, formalism, relativism (belief and conceptual), naturalism and non-naturalism, emotivism and prescriptive. This chapter begins with the question “What is Morality?” Feldman continues by outlining various kinds of moral philosophy and then argues as to why moral philosophy is valuable. He offers that the most useful aspect of moral philosophy is that it may demonstrate which moral principles are false, rather than which moral principles are wholly true.
