Abstract

How much understanding should be required of a person with respect to her actions and their implications for her to be autonomous with respect to her decisions to perform them? I defend a thin approach to the question of how much understanding of her acts a person should possess for her possibly to be autonomous with respect to her decisions to perform them: That a person could be autonomous with respect to her decision to perform a certain action if she understood both the nature of the act and its expected implications under the intensional description under which she intentionally performed it. This paper is divided into three sections. First, I argue that a concern for the moral value of autonomy does not undergird the ethical requirement to secure a person’s informed consent to her medical treatment. Second, I respond to several objections that have been leveled against this argument that focus on its implicit premise that only a thin understanding of one’s actions is required for one to be autonomous with respect to one’s decisions to perform them. I conclude by indicating why this minimalist account of autonomy that I defend is preferable to its more robust competitors.
