fear of death

“For I tell you, Athenians, the fear of death is simply this, thinking yourself wise when you are not; it’s thinking you know what you don’t know. Death may even be the greatest of all good things for a human being – no one knows, yet people fear it as if they knew for sure that it’s the greatest of bad things. And how is this kind of ignorance not reprehensible – thinking one knows what one doesn’t?”
