Since it is possible that thou mayest depart from life this very moment, regulate every act and thought accordingly. But to go away from among men, if there are gods, is not a thing to be afraid of, for the gods will not involve thee in evil; but if indeed they do not exist, or if they have no concern about human affairs, what is it to me to live in a universe devoid of gods or devoid of Providence? But in truth they do exist, and they do care for human things, and they have put all the means in man's power to enable him not to fall into real evils. And as to the rest, if there was anything evil, they would have provided for this also, that it should be altogether in a man's power not to fall into it. Now that which does not make a man worse, how can it make a man's life worse? But neither through ignorance, nor having the knowledge, but not the power to guard against or correct these things, is it possible that the nature of the universe has overlooked them; nor is it possible that it has made so great a mistake, either through want of power or want of skill, that good and evil should happen indiscriminately to the good and the bad. But death certainly, and life, honour and dishonour, pain and pleasure, all these things equally happen to good men and bad, being things which make us neither better nor worse. Therefore they are neither good nor evil.
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.
