 Although the above assumptions rule out the possibility of posthumous harm, they are entirely consistent, we have seen, with the possibility of mortal harm, the possibility that people are harmed by dying. (We might think otherwise if, as some theorists do, we assume that a person no longer exists at the time she dies. Joel Feinberg 1984, following Barbara Levenbook 1984, defined death as “the first moment of the subject’s nonexistence,” which makes death something that occurs after a person has ceased to exist, and suggests that by ruling out the possibility that a person is harmed by things that occur after she ceases to exist we rule out the possibility of mortal harm.)
