Nothing outside the will can hinder or harm the will; it can only harm itself. If then we accept this, and, when things go amiss, are inclined to blame ourselves, remembering that judgment alone can disturb our peace and constancy, I swear to you by all the gods that we have made progress.
EpictetusIf 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?
Epictetus
