„If, I say now, when, as I conceive and imagine, God orders me to fulfill the philosopher's mission of searching into myself and other men, I were to desert my post through fear of death, or any other fear; that would indeed be strange, and I might justly be arraigned in court for denying the existence of the gods… then I would be fancying that I was wise when I was not wise. For this fear of death is indeed the pretense of wisdom, and not real wisdom, being the appearance of knowing the unknown; since no one knows whether death, which they in their fear apprehend to be the greatest evil, may not be the greatest good. …this is the point in which, as I think, I am superior to men in general, and in which I might perhaps fancy myself wiser than other men — that whereas I know but little of the world below, I do not suppose that I know: but I do know that injustice and disobedience to a better, whether God or man, is evil and dishonorable, and I will never fear or avoid a possible good rather than a certain evil.“
Plato, Apology, 29a–b 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."
