In this book, David Edmonds, coauthor of the best-selling Wittgenstein's Poker, tells the riveting story of why and how philosophers have struggled with the ethical dilemma posed by the trolley problem. In the process, he provides an entertaining and informative tour through the history of moral philosophy. "Edmonds should be congratulated on his grand undertaking, and what I take to be his successful illumination of an important problem."---Joel Dittmer, Philosophy in Review
