Marcus Aurelius
Meditations 11.13
Suppose any man shall despise me. Let him look to that himself. But I will look to this, that I be not discovered doing or saying anything deserving of contempt. Shall any man hate me? Let him look to it. But I will be mild and benevolent towards every man, and ready to show even him his mistake, not reproachfully, nor yet as making a display of my endurance, but nobly and honestly, like the great Phocion, unless indeed he only assumed it. For the interior [parts] ought to be such, and a man ought to be seen by the gods neither dissatisfied with anything nor complaining. For what evil is it to thee, if thou art now doing what is agreeable to thy own nature, and art satisfied with that which at this moment is suitable to the nature of the universe, since thou art a human being placed at thy post in order that what is for the common advantage may be done in some way?
Marcus Aurelius, Meditations 11.13, translated by George Long
What if a man think scorn of me? That will be his affair. But it will be mine not to be found doing or saying anything worthy of scorn. But what if he hate me? That will be his affair. But I will be kindly and goodnatured to everyone, and ready to shew even my enemy where he has seen amiss, not by way of rebuke nor with a parade of forbearance, but genuinely and chivalrously like the famous Phocion, unless indeed he was speaking ironically. For such should be the inner springs of a man's heart that the Gods see him not wrathfully disposed at any thing or counting it a hardship. What evil can happen to thee if thou thyself now doest what is congenial to thy nature, and welcomest what the Universal Nature now deems well-timed, thou who art a man intensely eager that what is for the common interest should by one means or another be brought about?
Marcus Aurelius, Meditations 11.13, translated by C. R. Haines
