“If a person had delivered up your body to some passer-by, you would certainly be angry. And do you feel no shame in delivering up your own mind to any reviler, to be disconcerted and confounded?”
—The Enchiridion of Epictetus
Even this English translation is difficult to parse. I read it like this: if we wouldn't want others to physically control us, why do we allow others to control our minds by getting under our skin?
