 However, the desire-based case for the possibility of posthumous harm remains controversial. It will be rejected by theorists who doubt that people are harmed by events that do not modify their intrinsic features, and by theorists who think that it hinges on the possibility of backwards causation, of course. Velleman (1991, p. 339) rejects the desire-based case on the grounds that “we think of a person's current well-being as a fact intrinsic to the present, not as a relation that he currently bears to his future.” Some theorists echo a criticism that was offered by Partridge (1981, p. 246). Consider an event that thwarts one of a person's desires. To harm her by virtue of thwarting that desire, Partridge claims, the event must occur while she still has that desire, while she still cares about whether it is fulfilled, but she and her desire are gone by the time a posthumous event occurs. For some theorists (Vorobej, 1998, Suits 2001), the point is that we have no reason to care whether our desires are fulfilled by events that occur once we no longer have those desires, and we no longer have desires after we die. Parfit resisted this charge by noting that while some of our desires are conditional on their own persistence (we want them fulfilled at a time only on condition that we will still have them at that time), others are not.
