This first-rate introduction to ethical theory contains sections on various forms of ethical theory, such as egoism, virtue ethics, divine command theory, and consequentialism. Each section includes two or three of the most important contributions to the field, together with brief introductions by the editors. The second edition contains an improved approach to applied ethics. 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 edition also contains an improved section on feminist ethical theory.
