This is the third edition of Cahn and Markie's successful anthology for introductory ethics course. In some ways it is three books under one cover: first, a chronologically arranged history of ethics;second, a recent ethical theory collection; and third, a contemporary moral problems reader. The book's comprehensiveness and flexibility have made it attractive to a wide range of professors, allowing them to choose each semester how much emphasis to give to history, theory and moral problems. The edition includes added selections on issues such as euthanasia, abortion and the death penalty.
