This is ethical theory

"Professor Narveson distinguishes between a more general subject that may be called ethics and moral theory in particular, the main topic of this book. He gives a clear and precise account of the many explanations of right and wrong recommended by philosophers, covering such points of view as utilitarianism, natural law, egoism, moral relativism, virtue ethics, and religious derivations of ethics, and also explains the metaethical theories such as intuitionism, emotivism, and prescriptivism." "This Is Ethical Theory is both an introduction to ethical theory for those new to the field and a fresh exposition of Narveson's own approach, a form of contractarianism, which he develops after exposing the difficulties that arise with other approaches."--Jacket.
