 Now imagine a Corpse Reanimator, a device that moves molecules back to where they were prior to the death of the creature that left the corpse, and restarts its vital activities. Some theorists say that I continue my existence as a corpse if it remains in good shape; they will assume that I remain in existence after losing my life, and continue my existence after the Corpse Reanimator does its work. On their view the Corpse Reanimator restores my life--it gives me back the capacity to engage in vital activities.
