Implications of fission, fusion and teletransportation to a view of personal identity through psychological continuity

Giving a robust account of personal identity has been a major metaphysical goal. There have been numerous accounts of exactly what constitutes personal identity, including theories of physical and psychological continuity. In this essay, I shall focus on the view of identity as psychological continuity and on how the recent ideas of teletransportation, fission and fusion affect such a view. I shall explore several new consequences of these ideas and show how the psychological continuity approach to identity can address these challenges in interesting – if initially unintuitive – ways.
