 A proxy approach also raises the difficult question of how the trustee can acquire the moral and epistemic authority to speak for an individual with radical cognitive disabilities. Legal systems assign trustees or guardians to represent the “best interests” of individuals too immature or impaired to make, or to have made, their own judgments. But it is not clear how someone gets “appointed” as a trustee for purposes of securing moral status. Moreover, even those closest and most committed to an individual with radical cognitive impairments may find it hard to discern his interests, and distinguish them from their own “judgment-sensitive” attitudes.
