"When you think of your own death, the fact that all the good things in life will come to an end is certainly a reason for regret. But that doesn’t seem to be the whole story. Most people want there to be more of what they enjoy in life, but for some people, the prospect of nonexistence is itself frightening, in a way that isn’t adequately explained by what has been said so far. The thought that the world will go on without you, that you will become nothing, is very hard to take in. It’s not clear why. We all accept the fact that there was a time before we were born, when we didn’t yet exist—so why should we be so disturbed at the prospect of nonexistence after our death? But somehow it doesn’t feel the same. The prospect of nonexistence is frightening, at least to many people, in a way that past nonexistence cannot be. The fear of death is very puzzling, in a way that regret about the end of life is not. It’s easy to understand that we might want to have more life, more of the things it contains, so that we see death as a negative evil. But how can the prospect of your own nonexistence be alarming in a positive way? If we really cease to exist at death, there’s nothing to look forward to, so how can there be anything to be afraid of? If one thinks about it logically, it seems as though death should be something to be afraid of only if we will survive it, and perhaps undergo some terrifying transformation. But that doesn’t prevent many people from thinking that annihilation is one of the worst things that could happen to them."
