Death: The asymmetry mystery.

As the Roman philosopher Lucretius asked, why do we fear and regret death, but do not regret not having been born earlier, when death and prenatal nonexistence are mirror images? Both deprive us of goods we might have had, and this deprivation most plausibly explains the badness of death. This paper first considers and rejects explanations other than the deprivation of goods. It then suggests an explanation in terms of a state of which death deprives us, and which is itself asymmetrical in regard to the future and the past.
