Abstract
Jeff McMahan's impressive recent defence of the embodied mind theory of personal identity in his highly acclaimed work The Ethics of Killing has undoubtedly reawakened belief that physical continuity is a necessary component of the relation that matters in our self-interested concern for the future. My aim in this paper is to resist this belief in a somewhat roundabout way. I want to address this belief in a somewhat roundabout way by revisiting a classic defence of the belief that enormous changes in the contents of a person's psychology does not preclude justified fear of future pain. I have in mind Bernard Williams' The Self and the Future (1970) in which he argues, against the psychological view, that physical continuity is necessary for survival. I examine Williams' second thought experiment which ostensibly supports that intuition and afterwards defend two related claims. First, I argue that a close examination of the second thought experiment reveals that one's prior commitments to a particular criterion of personal identity can influence one's response to that thought experiment. Second, I argue that Williams' second thought experiment is set out in questionbegging terms. I do not claim, however, that the intuition under consideration lacks justification; I only claim that Williams' second thought experiment does not provide the needed support
