"Someone might say, 'Socrates, can you not go away from us and live quietly, without talking?' Now this is the hardest thing to make some of you believe. For if I say that such conduct would be disobedience to the god and therefore I cannot keep quiet, you will think I am jesting and will not believe me; and if again I say that to talk every day about virtue (ἀρετῆς) and the other things about which you hear me talking and examining myself and others is the greatest good to man, and that the unexamined life is not worth living [or: the unexamined life is not to be lived by man (ὁ δὲ ἀνεξέταστος βίος οὐ βιωτὸς ἀνθρώπῳ)], you will believe me still less. This is as I say, gentlemen, but it is not easy to convince you" (Apology 37e-38a).
