This book is exactly what it says it includes, the basic (and essential) writings of moral philosophy. It offers the most central and important articles/books/arguments for ethical theories such as Utilitarianism, Deontological Ethics, Cultural Relativism, etc. It ranges from Plato to Peter Singer and beyond. Normally, you'd have to buy numerous books to get all this philosophy, but it's all compiled together for a very low price. This book could easily be used for an introductory ethics class since it offers so much, and even more advance classes since many works can be exhaustively studied in their own courses. Once I saw this in my campus bookstore I knew I had to purchase it.
