Leading scholars debate politically progressive perspectives on bioethics and the implications for society, politics, and science in the twenty-first century. Bioethics has become increasingly politicized over the past decade. Conservative voices dominated the debate at first, but the recent resurgence of progressivism and the application of its fundamental values (social justice, critical optimism, practical problem solving) to bioethical issues have helped correct this ideological imbalance. Progress in Bioethics is the first book to debate the meaning of progressive bioethics and to offer perspectives on the topic both from bioethicists who consider themselves progressive and from bioethicists who do not. It aims to begin a dialogue and to provide a foothold for readers interested in understanding the field. The chapter authors, leading scholars in the field, discuss the meaning of progressive bioethics, the rise of conservative bioethics, the progressive stance toward biotechnology, the interplay of progressive bioethics and religion, and progressive approaches to such specific policy issues as bioethics commissions, stem cell research, and health-care reform.
