Abstract

According to Parfit’s assessment of fission, the fissioner can have prudential concern for each of the post-fission people and that concern will be rational in virtue of some relation he bears to those post-fission people. Parfit suggests that it is plausible that the relation that grounds rational prudential concern is not identity, but some other relation. This argument can be challenged by reference to Velleman’s account of anticipating having an experience on the reasonable assumption that prudential concern with respect to a person P consists, in part, in the ability to anticipate having certain experiences of P. According to Velleman, the fissioner cannot anticipate having the experiences of the fission products. In this paper, I suggest, first, that even if we accept Velleman’s account of anticipating having an experience, there are variants of fission in which his account is satisfied and, second, that his account may have the implication that prudential concern does not require anticipatory concern.
