'The philosophy of ethics has been central to understanding human interaction since ancient times. Now Patrick Colm Hogan, the most important researcher in the twenty-first century on the relationships between psychology and worldwide literature, has written a fascinating update. He says that ethical actions typically 'oppose egocentric self-interest' and are often based in empathy. With this beginning, and explorations that range from Shakespeare's plays to Chinese poetry and a German movie, he deepens our understanding of how we might act for the best towards others.' Keith Oatley, author of Our Minds, Our Selves: A Brief History of Psychology
