For the Greek Epicurus and the Roman Lucretius, living with our knowledge of mortality requires that “we become aware of our fear of death, then recognize that it is irrational to be afraid of death. Dead people are devoid of all sensations, just as we all were before we were conceived. No one is terrified of the time before they were born, so why fret about death, since it is precisely the same insensate state that prevailed for eons before our time?”
