Meditations 8.46

Nothing can happen to any man which is not a human accident, nor to an ox which is not according to the nature of an ox, nor to a vine which is not according to the nature of a vine, nor to a stone which is not proper to a stone. If then there happens to each thing both what is usual and natural, why shouldst thou complain? For the common nature brings nothing which may not be borne by thee.

Marcus Aurelius, Meditations 8.46, translated by George Long

Nothing can befall a man that is not a contingency natural to man; nor befall an ox, that is not natural to oxen, nor a vine that is not natural to a vine, nor a stone that is not proper to it. If therefore only what is natural and customary befalls each, why be aggrieved? For the common Nature brings thee nothing that thou canst not bear.

Marcus Aurelius, Meditations 8.46, translated by C. R. Haines
