This volume meets the increasing interest in a range of philosophical issues connected with the nature and significance of life and death, and the ethics of killing. What is it to be alive and to die? What is it to be a person? What must time be like if we are to persist? What makes one life better than another? May death or posthumous events harm the dead? The chapters in this volume address these questions, and also discuss topical issues such as abortion, euthanasia, and suicide. They explore the interrelation between the metaphysics, significance, and ethics of life and death, and they discuss the moral significance of killing both people and animals, and the extent to which death harms them. The volume is for all those studying the philosophy of life and death, for readers taking applied ethics courses, and for those studying ethics and metaphysics more generally.
