14. Whatever man thou meetest with, immediately say to thyself: What opinions has this man about good and bad? For if with respect to pleasure and pain and the causes of each, and with respect to fame and ignominy, death and life, he has such and such opinions, it will seem nothing wonderful or strange to me if he does such and such things; and I shall bear in mind that he is compelled to do so. 15. Remember that as it is a shame to be surprised if the fig-tree produces figs, so it is to be surprised if the world produces such and such things of which it is productive; and for the physician and the helmsman it is a shame to be surprised if a man has a fever, or if the wind is unfavorable. 16. Remember that to change thy opinion and to follow him who corrects thy error is as consistent with freedom as it is to persist in thy error. For it is thy own, the activity which is exerted according to thy own movement and judgment, and indeed according to thy own understanding too. 17. If a thing is in thy own power, why dost thou do it? but if it is in the power of another, whom dost thou blame,—the atoms [chance] or the gods? Both are foolish. Thou must blame nobody. For if thou canst, correct [that which is the cause]; but if thou canst not do this, correct at least the thing itself; but if thou canst not do even this, of what use is it to thee to find fault? for nothing should be done without a purpose. 18. That which has died falls not out of the universe. If it stays here, it also changes here, and is dissolved into its proper parts, which are elements of the universe and of thyself. And these too change, and they murmur not. 19. Everything exists for some end,—a horse, a vine. Why dost thou wonder? Even the sun will say, I am for some purpose, and the rest of the gods will say the same. For what purpose then art thou,—to enjoy pleasure? See if common sense allows this. 20. Nature has had regard in everything no less to the end than to the beginning and the continuance, just like the man who throws up a ball. What good is it then for the ball to be thrown up, or harm for it to come down, or even to have fallen? and what good is it to the bubble while it holds together, or what harm when it is burst? The same may be said of a light also. 21. Turn it [the body] inside out, and see what kind of thing it is; and when it has grown old, what kind of thing it becomes, and when it is diseased. Short lived are both the praiser and the praised, and the rememberer and the remembered: and all this in a nook of this part of the world; and not even here do all agree, no, not any one with himself: and the whole earth too is a point. 22. Attend to the matter which is before thee, whether it is an opinion or an act or a word. Thou sufferest this justly: for thou choosest rather to become good to-morrow than to be good to-day.
