If you think that only which is your own to be your own, and if you think that what is another's, as it really is, belongs to another, no man will ever compel you, no man will hinder you, you will never blame any man, you will accuse no man, you will do nothing involuntarily, no man will harm you, you will have no enemy, for you will not suffer any harm.
-Epictetus, The Handbook
