Thirty-four contributors reflect the interdisciplinarity that is characteristic of bioethics, and its increasingly international character. Thirty topics are covered in original essays written by some of the world's leading figures in the field, as well as by some newer 'up-and-comers'. The essays address both perennial issues, such as the methodology of bioethics, autonomy, justice, death, and moral status, and newer issues, such as biobanking, stem cell research, cloning, pharmacogenomics, and bioterrorism. Other topics concern mental illness and moral agency, the rule of double effect, justice and the elderly, the definition of death, organ transplantation, feminist approaches to commodification of the body, life extension, advance directives, physician-assisted death, abortion, genetic research, population screening, enhancement, research ethics, and the implications of public and global health for bioethics. Anyone who wants to know how the central debates in bioethics have developed in recent years, and where the debates are going, will want to consult this book. It will be an invaluable resource not only for scholars and graduate students in bioethics, but also for those in philosophy, medicine, law, theology, social science, public policy, and public health who wish to keep abreast of developments in bioethics.
