In addressing the Lucretian symmetry problem, the content-based approach attends to the difference between the contents of the actual life and those of relevant possible lives of a person. According to this approach, the contents of a life with an earlier beginning would substantially differ from, and thus be discontinuous with, the contents of the actual life, whereas the contents of a life with the same beginning but a later death would be continuous with the contents of the actual life. (...) In this paper, I examine two versions of the content-based approach: the identity account and the preference account. The identity account holds that, in the sense of identity which is relevant to the evil of nonexistence, the subject of the actual life, though identical to the person in the life with a later death, is distinct from the subject of the life with an earlier beginning. The preference account maintains that, given one’s attachments to actual particulars, a life with an earlier beginning is not rationally preferable to one’s actual life, whereas a life with a later death is. I argue that each version of the content-based approach is implausible, while discussing some of the complications that face each of them. (shrink)

If earlier-than-necessary death is bad because it deprives individuals of additional good life, then why isn't later-than-necessary conception bad for the same reason? Deprivationists have argued that prenatal non-existence is not bad because it is impossible to be conceived earlier, but postmortem non-existence is bad because it is possible to live longer. Call this the Impossibility Solution. In this paper, I demonstrate that the Impossibility Solution does not work by showing how it is possible to be conceived earlier in the (...) same senses it is possible to live longer. I then offer a solution to the Asymmetry Problem by suggesting a novel way to separate the badness of each type of non-existence from the type, and frequency, of attitudes we should have towards each type of non-existence. Even if both types of non-existence are equally bad, certain contingent facts about our postmortem non-existence provide reason for the badness of early deaths to be more frequently salient than the badness of late conceptions.

Why do we wish to die later but do not wish to have been created earlier? There is no puzzle here. It is false that if we had been created earlier we would have lived longer lives. Why don’t we wish to have been created earlier but with our actual times of death? That wish simply is not mandated by the more general wish to have lived a longer life. Furthermore, one might prefer one’s actual life to the better, but (...) considerably different, life one would have lived at an earlier time. (shrink)

It seems that people typically prefer dying later to dying earlier. It also seems that people typically do not prefer having been created earlier to having been created later. Lucretius’ Puzzle is the question whether anything typically rationally recommends having a preference for dying later to dying earlier over having a preference for having been created earlier to having been created later. In this paper, I distinguish among three ways in which Lucretius’ Puzzle can be understood and say how I (...) think they ought to be answered. (shrink)
