From Rusticus I received the impression that my character required improvement and discipline; and from him I learned not to be led astray to sophistic emulation, nor to writing on speculative matters, nor to delivering little hortatory orations, nor to showing myself off as a man who practises much discipline, or does benevolent acts in order to make a display; and to abstain from rhetoric, and poetry, and fine writing; and not to walk about in the house in my outdoor dress, nor to do other things of the kind; and to write my letters with simplicity, like the letter which Rusticus wrote from Sinuessa to my mother; and with respect to those who have offended me by words, or done me wrong, to be easily disposed to be pacified and reconciled, as soon as they have shown a readiness to be reconciled; and to read carefully, and not to be satisfied with a superficial understanding of a book; nor hastily to give my assent to those who talk overmuch; and I am indebted to him for being acquainted with the discourses of Epictetus, which he communicated to me out of his own collection.
From Maximus I learned self-government, and not to be led aside by anything; and cheerfulness in all circumstances, as well as in illness; and a just admixture in the moral character of sweetness and dignity, and to do what was set before me without complaining. I observed that everybody believed that he thought as he spoke, and that in all that he did he never had any bad intention; and he never showed amazement and surprise, and was never in a hurry, and never put off doing a thing, nor was perplexed nor dejected, nor did he ever laugh to disguise his vexation, nor, on the other hand, was he ever passionate or suspicious. He was accustomed to do acts of beneficence, and was ready to forgive, and was free from all falsehood; and he presented the appearance of a man who could not be diverted from right rather than of a man who had been improved. I observed, too, that no man could ever think that he was despised by Maximus, or ever venture to think himself a better man. He had also the art of being humorous in an agreeable way.
If any have offended against thee, consider first: What is my relation to men, and that we are made for one another... Remember these nine rules, as if thou hadst received them as a gift from the Muses, and begin at last to be a man while thou livest.
