9. As those who oppose you in the path of right reason have no power to divert you from sane action, so let them not turn you away from amenity towards themselves. Be watchful alike to persist in stable judgment and action, and in meekness towards those who would hinder or otherwise molest you. It is equally weak to grow angry with them or to desist from action and submit to defeat. Both are equally deserters-- he who runs away, and he who refuses to stand by friend and kinsman.
10. Nature cannot be inferior to Art. The Arts are but imitations of Nature. If this be so, that Nature which is the most perfect and comprehensive of all cannot be inferior to the best artistic skill. Now all Arts use inferior material for higher purposes; so also then does universal Nature. Hence the origin of justice, from which again the other virtues spring. Justice cannot be preserved if we are solicitous about things indifferent, if we are easily deceived, rash, and changeable.
11. If those things, the pursuit and avoidance of which trouble you, come not to you; but, as it happens, you go to them; then let your judgment be at peace concerning them, they will remain motionless, and you will no more be seen pursuing or avoiding them.
12. The sphere of the soul attains to perfect shape when it neither expands to what is without, nor contracts upon what is within; neither wrinkles nor collapses, but shines with a radiance whereby it discerns the truth of all things, both without itself and within.
13. Does any man contemn me? Let him look to that. And let me look to it that I be found doing or saying nothing worthy of his contempt. Does any one hate me? That is his affair. I shall be kind and good-natured to every one, and ready to shew his mistake to him that hates me; not in order to upbraid him, or to make a show of my patience, but from genuine goodness, like Phocion, if he indeed was sincere. Your inward character should be such that the Gods may see you neither angry nor repining at anything. What evil is it for you now to act according to your nature, and to accept now what is seasonable to the nature of the Universe; you, a man appointed to do some service for the common good?
14. Although they despise, yet they flatter one another. Although they desire to overtop, yet they cringe to one another.
