Thou sayest, Men cannot admire the sharpness of thy wits.- Be it so: but there are many other things of which thou canst not say, I am not formed for them by nature. Show those qualities then which are altogether in thy power, sincerity, gravity, endurance of labour, aversion to pleasure, contentment with thy portion and with few things, benevolence, frankness, no love of superfluity, freedom from trifling magnanimity. Dost thou not see how many qualities thou art immediately able to exhibit, in which there is no excuse of natural incapacity and unfitness, and yet thou still remainest voluntarily below the mark? Or art thou compelled through being defectively furnished by nature to murmur, and to be stingy, and to flatter, and to find fault with thy poor body, and to try to please men, and to make great display, and to be so restless in thy mind? No, by the gods: but thou mightest have been delivered from these things long ago. Only if in truth thou canst be charged with being rather slow and dull of comprehension, thou must exert thyself about this also, not neglecting it nor yet taking pleasure in thy dulness.
Be not disgusted, nor discouraged, nor dissatisfied, if thou dost not succeed in doing everything according to right principles; but when thou bast failed, return back again, and be content if the greater part of what thou doest is consistent with man's nature, and love this to which thou returnest; and do not return to philosophy as if she were a master, but act like those who have sore eyes and apply a bit of sponge and egg, or as another applies a plaster, or drenching with water. For thus thou wilt not fail to obey reason, and thou wilt repose in it. And remember that philosophy requires only the things which thy nature requires; but thou wouldst have something else which is not according to nature.- It may be objected, Why what is more agreeable than this which I am doing?- But is not this the very reason why pleasure deceives us? And consider if magnanimity, freedom, simplicity, equanimity, piety, are not more agreeable. For what is more agreeable than wisdom itself, when thou thinkest of the security and the happy course of all things which depend on the faculty of understanding and knowledge?
When thou hast assumed these names, good, modest, true, rational, a man of equanimity, and magnanimous, take care that thou dost not change these names; and if thou shouldst lose them, quickly return to them. And remember that the term Rational was intended to signify a discriminating attention to every several thing and freedom from negligence; and that Equanimity is the voluntary acceptance of the things which are assigned to thee by the common nature; and that Magnanimity is the elevation of the intelligent part above the pleasurable or painful sensations of the flesh, and above that poor thing called fame, and death, and all such things.
Acquire the contemplative way of seeing how all things change into one another, and constantly attend to it, and exercise thyself about this part of philosophy. For nothing is so much adapted to produce magnanimity. Such a man has put off the body, and as he sees that he must, no one knows how soon, go away from among men and leave everything here, he gives himself up entirely to just doing in all his actions, and in everything else that happens he resigns himself to the universal nature.
