What makes action right or wrong? Why is something good or bad? How does one make moral decisions about what is right and good? These are among the main questions in ethics that are the subject of moral theory. This book explores some of the most historically important and currently debated moral theories about the nature of the right and good. After an introduction to the main aims and methods of evaluating a moral theory, the remaining chapters in this book are devoted to an examination of various moral theories, including the divine command theory, moral relativism, natural law theory, Kant's moral theory, moral pluralism, virtue ethics and moral particularism. Providing an introduction to moral theory that explains and critically examines the theories of such classic moral philosophers as Aristotle, Aquinas, Kant, Bentham, Mill and Ross, this book acquaints students with the work of contemporary moral philosophers.
