This anthology is designed for use as a brief introduction to ethical theory. Included are sections on various forms of ethical theory: Ethical Relativism; Divine Command Theory; Egoism; Consequentialism; Deontology; Justice; Virtue Ethics; Feminist Ethics; and, new to the second edition, Pluralism. Each section includes two or three of the most important and interesting contributions to the field, together with brief introductions by the editors.

The second edition contains an improved approach to applied ethics. Whereas in the first edition the authors included a chapter at the end of the book that contained selections that dealt with moral problems, in the second edition they have dropped that chapter in favour of an approach that ties moral issues more closely to the moral theories. Each chapter on moral theories now includes a selection that deals with a moral problem, such as human cloning, abortion, and global warming. The selection illustrates how the relevant theoretical approach is put to use. There is therefore a much tighter integration between theory and practice than before. The new structural approach should make the book significantly more effective in the classroom. The new edition also contains an improved section on feminist ethical theory.
