Marcus Aurelius
Meditations 6.52
It is in our power to have no opinion about a thing, and not to be disturbed in our soul; for things themselves have no natural power to form our judgments.
Marcus Aurelius, Meditations 6.52, translated by George Long
We need not form any opinion about the thing in question or be harassed in soul, for Nature gives the thing itself no power to compel our judgments.
Marcus Aurelius, Meditations 6.52, translated by C. R. Haines
