Meditations 11.9

As those who try to stand in thy way when thou art proceeding according to right reason will not be able to turn thee aside from thy proper action, so neither let them drive thee from thy benevolent feelings toward them, but be on thy guard equally in both matters, not only in the matter of steady judgment and action, but also in the matter of gentleness to those who try to hinder or otherwise trouble thee. For this also is a weakness, to be vexed at them, as well as to be diverted from thy course of action and to give way through fear; for both are equally deserters from their post,—the man who does it through fear, and the man who is alienated from him who is by nature a kinsman and a friend.

Marcus Aurelius, Meditations 11.9, translated by George Long

As those who withstand thy progress along the path of right reason will never be able to turn thee aside from sound action, so let them not wrest thee from a kindly attitude towards them; but keep a watch over thyself in both directions alike, not only in steadfastness of judgment and action but also in gentleness towards those who endeavour to stand in thy path or be in some other way a thorn in thy side. For in fact it is a sign of weakness to be wroth with them, no less than to shrink from action and be terrified into surrender. For they that do the one or the other are alike deserters of their post, the one as a coward, the other as estranged from a natural kinsman and friend.

Marcus Aurelius, Meditations 11.9, translated by C. R. Haines
