“Between falsehood and useless truth there is little difference. As gold which he cannot spend will make no man rich, so knowledge which cannot apply will make no man wise.”

“The trouble about man is twofold. He cannot learn truths which are too complicated; he forgets truths which are too simple.”

“A wise man is cured of ambition by ambition itself; his aim is so exalted that riches, office, fortune, and favor cannot satisfy him.”

“There is no man...however wise, who has not at some period in his youth said things, or lived a life, the memory of which is so unpleasant to him that he would gladly expunge it. And yet he ought not entirely to regret it, because he cannot be certain that he has indeed become a wise man...”

“I mean that man is ruled by a tyrant whose name is Ignorance, and that is the tyrant I sought to overthrow. That is the tyrant which gave birth to monarchy, and monarchy is authority based on falsehood, whereas knowledge is authority based on truth. Man should be ruled by knowledge.”

“there is little difference between man and beast, but what ambition and glory makes.”
