This book is a discussion of philosophical, legal, and medical issues related to aging, dying, and death. It considers different views about whether and why death is bad for the person who dies, and whether these views bear on why it would be bad if there were no more persons at all. The book looks at how the general public is being asked to think about end-of-life issues by examining some questionnaires and conversation guides that have been developed. It also considers views about the process of dying and whether it might make sense to not resist death, or even to bring about the end of one’s life, given certain views about meaning in life and what things it is worth living on to get and do. Some hold that it is not only serious illness but ordinary aging that may give rise to some of these questions and the book considers various ways in which aging and the distribution of goods and bads in a life could occur. Physician-assisted suicide would be one way to end one’s life and the book examines arguments about its moral permissibility and whether or not it should be legalized as a matter of public policy. This discussion draws on capital punishment debates concerning state action and also on methods of balancing costs and benefits. The book examines the views of such prominent philosophers, doctors, and legal theorists as Shelly Kagan, Susan Wolf, Atul Gawande, Ezekiel Emanuel, Cass Sunstein, Neil Gorsuch, and others.
