The international growth and influence of bioethics has led some to identify it as a decisive shift in the location and exercise of 'biopower'. This book provides an in-depth study of how philosophers, lawyers and other 'outsiders' came to play a major role in discussing and helping to regulate issues that used to be left to doctors and scientists. It discusses how club regulation stemmed not only from the professionalising tactics of doctors and scientists, but was compounded by the 'hands-off' approach of politicians and professionals in fields such as law, philosophy and theology. The book outlines how theologians such as Ian Ramsey argued that 'transdisciplinary groups' were needed to meet the challenges posed by secular and increasingly pluralistic societies. It also examines their links with influential figures in the early history of American bioethics. The book centres on the work of the academic lawyer Ian Kennedy, who was the most high-profile advocate of the approach he explicitly termed 'bioethics'. It shows how Mary Warnock echoed governmental calls for external oversight. Many clinicians and researchers supported her calls for a 'monitoring body' to scrutinise in vitro fertilisation and embryo research. The growth of bioethics in British universities occurred in the 1980s and 1990s with the emergence of dedicated centres for bioethics. The book details how some senior doctors and bioethicists led calls for a politically-funded national bioethics committee during the 1980s. It details how recent debates on assisted dying highlight the authority and influence of British bioethicists.
