We will argue here that after more than 30 years of talk, theory, and clinical practice, we bioethicists still know far too little about what patients, subjects, and healthcare professionals are up to, morally. Bioethics is still near the beginning in grasping what it means to understand, much less to honor fully, the moral power and perspicacity of those bioethics is designed to serve. This is, of course, a serious charge, but one we will endeavor to show has merit. However, we want to be clear from the start that we do not gainsay the important work that has been done in and through the influence of bioethics, both as a field of practical engagement and as a cultural movement, in improving how healthcare is delivered and how human subjects are treated. Thirty or 40 years—depending on how one marks the beginning point—is a very short time, and it is hard to imagine that wholesale changes, all of them in the right direction, could be the outcome for a field this young. Hence, we do not intend the title, “One Cheer for Bioethics,” as a wholesale indictment, but as an indication that there is a great deal of work yet to be done, and that following the currently dominant direction of the field is not likely to get us there. Our aim is to indicate just where future work should be focused, and to do so we will need to be critical of some of the preoccupations of the last three decades.The authors thank Lida Anestidou, Mark Bliton, Ellen Clayton, Stuart Finder, Elizabeth Heitman, Joshua Perry, Annabeth Schenck, and Lucia Tanassi for helpful comments on earlier presentations and drafts of the ideas in this paper.
