It has been a pleasure to read these papers and to contemplate their importance for what I believe to be a useful and provocative prism though which to view the field of bioethics: the nature of moral consensus. In my own most extended contribution to this literature, Deciding Together, I did not attempt to prescribe so much as to understand the role of moral consensus in the practice of bioethics. At the end of the book, I expressed the hope that it might help trigger an examination of bioethics and moral consensus. Though a few others shared my interest at that time (in particular Tris Engelhardt, for whose early encouragement I remain deeply grateful), with this set of stimulating papers the conversation has finally begun in earnest.
