This volume brings together original essays by many of the best and most prominent figures in the emerging field of biomedical ethics and presents them in a dialogue that significantly updates their earlier work. Focusing on the moral dilemmas that recent medical advances have created at both ends of the life course, the contributors discuss such issues as patient autonomy, hospital policies of risk-management, new developments in the abortion debate, genetic counseling and perinatal care, euthanasia and physician-assisted suicide, testing and treatment policies for HIV infection, and fairness in allocating health care and donated organs.
