A concise, yet engaging introduction to the field of ethics, this volume offers a systematic study of the foundations of moral responsibility. Montague Brown guides the reader on an examination of a wide range of ethical positions, including relativism, emotivism, egoism, utilitarianism, Kantian formalism, and natural law. Brown explains not only the history behind the development of each position, but also the roles science, democracy, and religion play in moral thinking today. Students and teachers of philosophy, ethics, and religion, as well as the general reader, will find that this book tackles the serious issues and offers an insightful, accessible introduction to major ethical positions and the great moral philosophers.
