For not only do people envy those of the same trade and manner of life, but the rich envy the learned, and the famous the rich, and advocates sophists, aye, and freemen and patricians admire and think happy comedians starring it at the theatres, and dancers, and the attendants at kings' courts, and by all this envy give themselves no small trouble and annoyance.
§ xiv. But that every man has in himself the magazines of content or discontent, and that the jars containing blessings and evils are not on the threshold of Zeus,26 but lie stored in the mind, is plain from the differences of men's passions. For the foolish overlook and neglect present blessings, through their thoughts being ever intent on the future; but the wise make the past clearly present to them through memory. For the present giving only a moment of time to the touch, and then evading our grasp, does not seem to the foolish to be ours or to belong to us at all.

For as those in the schools, who deny the growth of our bodies by reason of the continual flux of substance, make each of us in theory different from himself and another man, so those who do not keep or recall to their memory former things, but let them drift, actually empty themselves daily, and hang upon the morrow, as if what happened a year ago, or even yesterday and the day before yesterday, had nothing to do with them, and had hardly occurred at all.
