“When a man has everything and does not know what more to do, he tries to teach his donkey to talk.”

“Man, who thinks he knows everything. But what does man know...Man cares only for himself, in his fear and hate.”

“In his own life, then, a man is not to expect happiness, only to profit by it gladly when it shall arise; he is on duty here; he knows not how or why, and does not need to know; he knows not for what hire, and must not ask. Somehow or other, though he does not know what goodness is, he must try to be good; somehow or other, though he cannot tell what will do it, he must try to give happiness to others.”

“At the beginning of human history, man lost some of the basic animal instincts in which an animal's behavior is embedded and by which it is secured. Such security, like paradise, is closed to man forever; man has to make choices. In addition to this, however, man has suffered another loss in his more recent development inasmuch as the traditions which buttressed his behavior are now rapidly diminishing. No instinct tells him what he has to do, and no tradition tells him what he ought to do; sometimes he does not even know what he wishes to do. Instead, he either wishes to do what other people do (conformism) or he does what other people tell him to do (totalitarianism).”

“Knowing yourself means knowing, first, what it is to be a person; secondly, knowing what it is to be the kind of person you are; and thirdly, knowing what it is to be the person you are and nobody else is. Knowing yourself means knowing what you can do; and since nobody knows what they can do until they try, The only clue to what man can do is what man has done. The value of history, then, is that it teaches us what man has done and thus what man is.”

“The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.”
