Marcus Aurelius
Meditations 7.14
Let there fall externally what will on the parts which can feel the effects of this fall. For those parts which have felt will complain, if they choose. But I, unless I think that what has happened is an evil, am not injured. And it is in my power not to think so.
Marcus Aurelius, Meditations 7.14, translated by George Long
Let any external thing, that will, be incident to whatever is able to feel this incidence. For that which feels can, if it please, complain. But I, if I do not consider what has befallen me to be an evil, am still unhurt. And I can refuse so to consider it.
Marcus Aurelius, Meditations 7.14, translated by C. R. Haines
