This reader contains 72 classical and contemporary articles organized around 13 crucial issues in ethical theory: the nature of ethics, ethical relativism, ethical egoism and evolutionary ethics, value, utilitarianism, deontological ethics, virtue ethics, the fact/value problem, moral realism and skepticism, morality and self-interest, ethics and religion, justice, and rights. The articles are arranged within a coherent, teachable framework in which presentation of each problem progresses from the classical to the contemporary, usually treating it in a dialectic (pro and con) format.
