The Western focus on personal autonomy as the normative basis for securing persons’ consent to their treatment renders this autonomy-based approach to informed consent vulnerable to the charge that it is based on an overly atomistic understanding of the person. This leads to a puzzle: how does this generally-accepted atomistic understanding of the person fits with the emphasis on familial consent that occurs when family members are provided with the opportunity to veto a prospective donor’s wish to donate after she (...) has died and her organs are being considered for harvesting? It is argued in this paper that this charge can be met and this puzzle dissolved once it is recognized that autonomy is an inherently social concept. (shrink)
