A passage from Marcus Aurelius
Marcus Aurelius, Meditations 4.36
✱
Let us try to persuade men of it. But act even against their will, when the principles of justice lead thee. If however any one by using force stands in thy way, betake thyself to contentment and tranquility, and at the same time employ the hindrance towards the exercise of some other virtue.
