This is an interesting, accessible and helpful introduction to ethics. It is a nicely written introduction to the topic of ethics, of use to both students and someone just interested in the topic. I liked the ordering of the chapters and the way the subject is introduced, and found the inclusion of Marxist and Nietzschian criticisms of ethics helpful. My only criticism, which is minor but just shaded me off giving the book 5 stars is that the first few chapters whilst helpful do sometimes pose too many questions. I know this is to stimulate the reader's thinking, but it did irritate me a tiny bit. If you want to study ethics seriously you will very soon get beyond this book, but it is a good place to start.
