This book explores and elaborates three theories of public reason, drawn from Rawlsian political liberalism, natural law theory, and Confucianism. Drawing together academics from these separate approaches, the volume explores how the three theories critique each other, as well as how each one brings its theoretical arsenal to bear on the urgent contemporary debate of medical assistance in dying. The volume is structured in two parts: an exploration of the three traditions, followed by an in-depth overview of the conceptual and historical background. In Part I, the three comprehensive opening chapters are supplemented by six dynamic chapters in dialogue with each other, each author responding to the other two traditions, and subsequently reflecting on the possible deficiencies of their own theories. The chapters in Part II cover a broad range of subjects, from an overview of the history of bioethics to the nature of autonomy and its status as a moral and political value. In its entirety, the volume provides a vibrant and exemplary collaborative resource to scholars interested in the role of public reason and its relevance in bioethical debate.
