A man who leads a life of tranquillity and reflection, who is not disturbed at home and meddles not with the affairs of the world, may keep his mind … - George Long

The emperor Antoninus was a practical moralist. From his youth he followed a laborious discipline, and though his high station placed him above all want or the fear of it, he lived as frugally and temperately as the poorest philosopher.

According to the subdivision of Cleanthes, Physic and Theology go together, or the study of the nature of Things, and the study of the nature of the Deity, so far as man can understand the Deity, and of his government of the universe. This division or subdivision is not formally adopted by Antoninus, for... there is no method in his book; but it is virtually contained in it.

A man's greatness lies not in wealth and station, as the vulgar believe, not yet in his intellectual capacity, which is often associated with the meanest moral character, the most abject servility to those in high places and arrogance to the poor and lowly; but a man's true greatness lies in the consciousness of an honest purpose in life, founded on a just estimate of himself and everything else, on frequent self-examination, and a steady obedience to the rule which he knows to be right, without troubling himself, as the emperor [Marcus Aurelius] says he should not, about what others may think or say, or whether they do or do not do that which he thinks and says and does.
