Marcus Aurelius
Meditations 1.9
From Sextus, a benevolent disposition, and the example of a family governed in a fatherly manner, and the idea of living conformably to nature; and gravity without affectation, and to look carefully after the interests of friends, and to tolerate ignorant persons, and those who form opinions without consideration: he had the power of readily accommodating himself to all, so that intercourse with him was more agreeable than any flattery; and at the same time he was most highly venerated by those who associated with him: and he had the faculty both of discovery and ordering, in an intelligent and methodical way, the principles necessary for life; and he never showed anger or any other passion, but was entirely free from passion, and also most affectionate; and he could express approbation without noisy display, and he possessed much knowledge without ostentation.
Marcus Aurelius, Meditations 1.9, translated by George Long
From Sextus, kindliness, and the example of a household patriarchally governed; and the conception of life in accordance with Nature; and dignity without affectation; and an intuitive consideration for friends; and a toleration of the unlearned and the unreasoning.
And his tactful treatment of all his friends, so that simply to be with him was more delightful than any flattery, while at the same time those who enjoyed this privilege looked up to him with the utmost reverence; and the grasp and method which he shewed in discovering and marshalling the essential axioms of life.
And never to exhibit any symptom of anger or any other passion, but to be at the same time utterly impervious to all passions and full of natural affection; and to praise without noisy obtrusiveness, and to possess great learning but make no parade of it.
Marcus Aurelius, Meditations 1.9, translated by C. R. Haines
