Meditations 8.56

To my own free will the free will of my neighbor is just as indifferent as his poor breath and flesh. For though we are made especially for the sake of one another, still the ruling power of each of us has its own office, for otherwise my neighbor's wickedness would be my harm, which God has not willed, in order that my unhappiness may not depend on another.

Marcus Aurelius, Meditations 8.56, translated by George Long

To my power of choice the power of choice of my neighbour is as much a matter of indifference as is his vital breath and his flesh. For however much we may have been made for one another, yet our ruling Reason is in each case master in its own house. Else might my neighbour's wickedness become my bane; and this was not God s will, that another might not have my unhappiness in his keeping.

Marcus Aurelius, Meditations 8.56, translated by C. R. Haines
