...if it is our wish, by greatness of mind, to pass beyond the narrow limits of human weakness, there is a great stretch of time through which we may roam. We may argue with Socrates, we may doubt with Carneades, find peace with Epicurus, overcome human nature with the Stoics, exceed it with the Cynics.… We may fairly say that they alone are engaged in the true duties of life who shall wish to have Zeno, Pythagoras, Democritus, and all the other high priests of liberal studies, and Aristotle and Theophrastus, as their most intimate friends every day. No one of these will be ‘not at home,’ no one of these will fail to have his visitor leave more happy and more devoted to himself than when he came, no one of these will allow anyone to leave him with empty hands; all mortals can meet with them by night or by day.
...No one of these will force you to die, but all will teach you how to die; no one of these will wear out your years, but each will add his own years to yours; conversations with no one of these will bring you peril, the friendship of none will endanger your life, the courting of none will tax your purse. From them you will take whatever you wish; it will be no fault of theirs if you do not draw the utmost that you can desire. What happiness, what a fair old age awaits him who has offered himself as a client to these! He will have friends from whom he may seek counsel on matters great and small, whom he may consult every day about himself, from whom he may hear truth without insult, praise without flattery, and after whose likeness he may fashion himself.
