Would You Kill the Fat Man?

"Lucid, witty, and beautifully written, this book is a pleasure to read. While providing an introduction to moral philosophy, it also presents engaging portraits of some of the greatest moral philosophers from Thomas Aquinas to the present day, and it makes the case for the relevance to ethics of the new experimental moral psychology. It is a tour de force."--Kwame Anthony Appiah, author of The Honor Code: How Moral Revolutions Happen
