A great resource for beginning ethics courses. The book is short and yet it richly embodies the methods of ethical thinking about practical moral problems that are hard for students to learn unless they see them in action. McGinn perspicuously sets out a small set of basic principles and then attacks the problems of our treatment of animals, abortion, sex, censorship, and so on, with a masterful blend of attention to real-life cases and imaginary thought experiments. McGinn hardly claims to have the last word on the complex issues he discusses, and students will find many exciting problems and points to take up.--Owen Flanagan, Duke University
