How ought we to understand the sources and limits of the authority of family members to make health care decisions for their decisionally incapacitated relatives? This question is becoming increasingly crucial as the population ages and the power of medical technology waxes. It is also becoming increasingly contested, as faith in advance directives shows signs of waning, and the moral complexities of intimate relationship become more theoretically patent.
This last point—the newly visible moral richness of intimate relationship—provides this paper with its field. I am interested in probing the images of the relationship between self and other, particularly self and intimate other, that seem presupposed by some leading attempts to determine the basis for proxy decision-making authority, and what constraints it must observe. In the light of both recent work in the philosophy of mind and considerations closer to common experience, the reigning images seem too slight to support the weight of current practices and beliefs about proxy authority; supplanting them with images more faithful to our experience will have implications for our practice with proxies.
