This is a theory of ethics that I think answers all moral questions with a single, universal moral rule. The book has the development of a system using common, universal ideas of what is right and wrong, good and bad. I also compare and contrast with some of the ideas of Immanuel Kant and Aristotle. The first section begins with a discussion of altruism and egoism, as many of the debates that I have heard in the past have been mostly about these positions. The second section is about morality and immorality and what makes actions moral or immoral.
