No area of practical philosophy receives stronger or more sustained attention than bioethics. It has been established as a staple course on university curricula across the world, influences the practice of professions within and beyond health care, and increasingly features in the public consciousness. This anthology gathers together original works from some of bioethics' most celebrated scholars. Focused on and around the works of John Harris, the book addresses the most debated issues in contemporary bioethics, and will serve as an excellent text and resource for students, scholars, and practitioners interested in bioethics. It includes chapters from some of the field's most noted scholars, such as Margaret Brazier, Raanan Gillon, Jonathan Glover, Ruth Macklin, as well as John Harris himself. The book offers Professor Harris's own reflections on the field of bioethics, to which he has contributed so much. It then, in two series of eight chapters, examines first theoretical issues in philosophical bioethics, and second practical issues and problems in the application of philosophical argument. The book closes with a chapter where Professor Harris responds critically to the book's contributors. Whilst challenging, the chapters are accessible to a broad international readership, providing fundamental insights into the nature and limitations of ethical argument.The book will serve as an excellent resource for students, scholars and practitioners interested in bioethics.
