“Can anything be imagined so ridiculous, that this miserable and wretched creature [man], who is not so much as master of himself, but subject to the injuries of all things, should call himself master and emperor of the world, of which he has not power to know the least part, much less to command the whole?”

“God has entrusted me with myself. No man is free who is not master of himself. A man should so live that his happiness shall depend as little as possible on external things. The world turns aside to let any man pass who knows where he is going.”

“He who controls others may be powerful, but he who has mastered himself is mightier still.”

“The Servant who really studies his Master gradually becomes like his master; gradually learns that he himself is the one who in the end does all the work and has all the power.”

“No man is free who is not master of himself.”

“Just as primitive man believed himself to stand face to face with demons and believed that could he but know their names he would become their master, so is contemporary man faced by this incomprehensible, which disorders his calculations. "If I can but grasp it, if I can but cognise it", so he thinks, "I can make it my servant.”
