Much recent thought on the ethics of new biomedical technologies, and work in ethics and political philosophy more generally, is committed to hidden and contestable views about the nature of biological reality. This selection of essays by Tim Lewens, a leading expert in the field, teases out these biological foundations of bioethical writing and subjects them to scrutiny. The topics covered include human enhancement, the risks of technical progress, the alleged moral threat of synthetic biology, the reality of human nature, the relevance of evolutionary psychology to social policy, the nature of the distinction between health and disease, and justice in healthcare decision-making.

This collection of essays focuses on the connection between biology and questions in ethics.

This new, thoroughly recast Second Edition has been acclaimed as "the most important book written since the beginning of that strange project called bioethics" (Stanley Hauerwas, Duke University). Its philosophical exploration of the foundations of secular bioethics has been substantially expanded. The book challenges the values of much of contemporary bioethics and health care policy by confronting their failure to secure the moral norms they seek to apply. The nature of health and disease, the definition of death, the morality of abortion, infanticide, euthanasia, physician-assisted suicide, germline genetic engineering, triage decisions and distributive justice in health care are all addressed within an integrated reconsideration of bioethics as a whole. New material has been added regarding social justice, health care reform and environmental ethics. The very possibility and meaning of a secular bioethics are re-explored.

There has been much attention devoted in recent years to the question of whether our moral principles can be related to our biological nature. This collection of new essays focuses on the connection between biology and foundational questions in ethics. The book asks such questions as whether humans are innately selfish, and whether there are particular facets of human nature that bear directly on social practices. This is the first book to offer this historical perspective on the relation of biology and ethics, and has been written by some of the leading figures in the history and philosophy of science, whose work stands very much at the cutting edge of these disciplines.

The aim of this book is to introduce and discuss bioethics in a three-synergistic way: from the foundations to the current debates in relation to healthcare and social bioethics, and thereafter the possible future challenges. In this sense, the target audience can be from diverse disciplines: life and medical sciences, law, philosophy, psychology, and education. The book will be useful to high school students, in their first contacts with bioethics, college students, teachers and researchers, and the general public interested in these controversial debates of the past, present and future of bioethics.

What is Bioethics? What are its goals and theoretical assumptions? Is it a unique discipline? Must medical ethics be grounded in clinical experience? How can ethical inquiry inform medicine's theory and practice? Must one have a definition of medicine before one can have a medical ethic? Does medicine have a unique or demarcating body of knowledge, methodology, or philosophy? These troubling questions are addressed by a distinguished roster of philosophers, theologians, lawyers, social scientists, physicians and scientists. The unifying theme of this text is a philosophical exploration of the history, nature, scope and foundations of bioethics. There is a critical evaluation of principled, communitarian, legal, narrative and feminist approaches. The book's interdisciplinary focus allows for a lively dialogue which includes papers and accompanying commentaries. Audience: Philosophers of science and medical ethicists, physicians, lawyers, policy makers.
