“So is man's heart. The desire to perform a work which will endure, which will survive him, is the origin of his superiority over all other living creatures here below. It is this which has established his dominion, and this it is which justifies it, over all the world.”

“True religion is that relationship, in accordance with reason and knowledge which man establishes with the infinite world around him, and which binds his life to that infinity and guides his actions.”

“All this is a preface to the fear and uncertainties which clamber over a man so that in his silly work he thinks he must be crazy because he is so alone.”

“Conversation is an art in which a man has all mankind for his competitors, for it is that which all are practising every day while they live.”

“Every human occupation has it repertoire of stock phrases, within which every man twists and turn until his death. His vocabulary, which seems so lavish, reduces itself to a hundred routine formulas at most, which he repeats over and over.”

“You will never have a greater or lesser dominion than that over yourself...the height of a man's success is gauged by his self-mastery; the depth of his failure by his self-abandonment. ...And this law is the expression of eternal justice. He who cannot establish dominion over himself will have no dominion over others.”
