At a time when ethical and political philosophy were thought passé, John Rawls gave serious attention to ethical questions, providing them with a renewed academic legitimacy. This helped fields of practical ethics such as bioethics become established in higher education and in public affairs. This essay addresses the influence Rawls has had on bioethics through both the style and the substance of his ethical argumentation. The essay argues that his distinctive rhetorical strategy and tone attempted to rein in the scope (...) of normative commitments in order to make an equilibrium between refined understandings of freedom and equality possible and sustainable. Bioethics has been strongly influenced by this approach to maintaining social stability in a liberal society that has become highly stratified and culturally diverse. Bioethics continues to echo the Rawlsian call for a calmly reasoned political life but finds that call increasingly difficult to answer. (shrink)
