other deceivers, when they are lying, try to speak in vague and ambiguous terms, afraid of being convicted; but Demosthenes, when he is cheating you, first adds an oath to his lie, calling down destruction on himself; and secondly, predicting an event that he knows will never happen, he dares to tell the date of it; and he tells the names of men, when he has never so much as seen their faces, deceiving your ears and imitating men who tell the truth. And this is, indeed, another reason why he richly deserves your hatred, that he is not only a scoundrel himself, but destroys your faith even in the signs and symbols of honesty.
