Meditations 5.16

Such as are thy habitual thoughts, such also will be the character of thy mind; for the soul is dyed by the thoughts. Dye it then with a continuous series of such thoughts as these: for instance, that where a man can live, there he can also live well. But he must live in a palace; well then, he can also live well in a palace. And again, consider that for whatever purpose each thing has been constituted, for this it has been constituted, and towards this it is carried; and its end is in that towards which it is carried; and where the end is, there also is the advantage and the good of each thing. Now the good for the reasonable animal is society; for that we are made for society has been shown above. Is it not plain that the inferior exists for the sake of the superior? But the things which have life are superior to those which have not life, and of those which have life the superior are those which have reason.

Marcus Aurelius, Meditations 5.16, translated by George Long

The character of thy mind will be such as is the character of thy frequent thoughts, for the soul takes its dye from the thoughts. Dye her then with a continuous succession of such thoughts as these: Where life is possible, there it is possible also to live well.—But the life is life in a Court. Well, in a Court too it is possible to live well. And again: A thing is drawn towards that for the sake of which it has been made, and its end lies in that towards which it is drawn and, where its end lies, there lie also its interest and its good. The Good, then, for a rational creature is fellowship with others. For it has been made clear long ago that we were constituted for fellowship. Or was it not obvious that the lower were for the sake of the higher and the higher for the sake of one another? And living things are higher than lifeless, and those that have reason than those that have life only.

Marcus Aurelius, Meditations 5.16, translated by C. R. Haines
