Alternate translation: "To fear death, is nothing else but to believe ourselves to be wise, when we are not; and to fancy that we know what we do not know. In effect, no body knows death; no body can tell, but it may be the greatest benefit of mankind; and yet men are afraid of it, as if they knew certainly that it were the greatest of evils."
Plato, Apology
