\nWhy on earth is it that, although we are all deceived by the same things and through the same means, we cannot cease from this folly?\n\nFor this kind of knavery has already occurred many times by many people.\n\nAnd while its success among others is perhaps not surprising, its success among those with whom the very source of such mischief exists [is indeed surprising].\n\nBut the cause is that what was well said by Epicharmus is not ready to hand:\n"Be sober and remember to disbelieve; these are the joints of the mind." —\nMedion, a city near Aetolia.\n\nPolybius in the eighteenth book.
