Book IX · 11
If thou art able, correct by teaching those who do wrong; but if thou canst not, remember that indulgence is given to thee for this purpose. And the gods, too, are indulgent to such persons; and for some purposes they even help them to get health, wealth, reputation; so kind they are. And it is in thy power also; or say, who hinders thee?
Marcus Aurelius, Meditations IX.11. Translated by George Long (1862). The Stoic Library.
