Before You Were Born
In one line Lucretius asked why we fear the time after death but not the time before birth.
Lucretius was a Roman poet of the first century BCE. His long poem, On the Nature of Things, sets out Epicurus’ teaching in Latin verse. Everything is atoms and void, nothing comes from nothing, and the mind is made of atoms that scatter at death.
From this he drew a comfort. Where death is, we are not, so there is no one left to be harmed. He added a mirror argument. Think of the endless time before you were born. It did not trouble you. The time after death is its mirror, so it should not trouble you either.
Critics reply that the two times differ. Thomas Nagel argued that death can harm a person by taking good years they would have had, while a much earlier birth may not have been possible. The habit worth taking is to ask what exactly in a fear is doing the frightening.
Go deeper
Lucretius also gave atoms a slight swerve, a tiny unpredictable turn in their fall. Without it, he thought, atoms would fall in parallel lines and never collide, and every motion would be fixed by the one before, leaving no room for free choice. Few modern readers accept the swerve, but the worry behind it, how freedom fits a world of causes, is still debated.
The two kinds of fear

Sam lies awake afraid of death. A friend asks him to say what exactly he fears. He lists pain at the end, leaving his daughter, and the thought of the world going on without him.
The friend points out that the first two are about dying and about others. The third is about being dead, and Sam was calm about the world before he was born. Sam still cares about his daughter, but the third fear loosens.
Try this today Write down what you fear about death, and mark which parts are about dying and which about being dead.
