The Center for Bioethics at the University of Pennsylvania is the internationally recognized leader in bioethical education and research. Its interdisciplinary faculty is drawn from the fields of medicine, law, nursing, education, philosophy, psychology, and religious studies. Arthur L. Caplan, the Center's founding director, is recognized as one of the most influential experts in bioethics. He has authored numerous books and articles, and served as the Chair of the Advisory Committee to the United Nations on human cloning. The Penn Center's leading fellows, Autumn Fiester and Vardit Ravitsky, have combined their expertise with Dr. Caplan and over 80 other contributors to create The Penn Center Guide to Bioethics--the foremost authority on both traditional and cutting-edge bioethical issues. The Penn Guide navigates uncharted ethical terrains, undoubtedly shaping both academic and public discourses on the challenging controversies generated by new technologies, theories, and medical advances. This volume represents the Penn Center's distinct, pioneering approach to bioethics, one that emphasizes empirical treatment of bioethical issues, and the integration of bioethical scholarship with practical application. The Penn Guide will be the definitive text for policy makers, health practitioners, researchers, and students. This book will also inform the general public, patients, and family members as they seek answers to the bioethical issues of the day.
