"[The Roman philosopher Lucretius] thought it a mistake to find the prospect of my death upsetting. Yes, as the deprivation account points out, after death we can't enjoy life's pleasures. But wait a minute, says Lucretius. The time after I die isn't the only period during which I won't exist. What about the period before my birth? If nonexistence is so bad, shouldn't I be upset by the eternity of nonexistence before I was born? But that's silly, right? Nobody is upset about that. So, he concludes, it doesn't make any sense to be upset about the eternity of nonexistence after you die, either."
