   “Is it not enough, at any rate, to strike the thing called ‘Fame’ into total silence for a wise man? For fools and unreflective persons, she is and will be very noisy, this ‘Fame’, and talks of her ‘immortals’ and so forth: but if you will consider it, what is she?”

   “But perhaps, too, it is worth recalling where hasty, unreflective action has taken us in recent years.”
