“What greater wealth is there than to own your life and to spend it on growing? Every living thing must grow. It can't stand still. It must grow or perish.”

“Man—every man—is an end in himself, not a means to the ends of others; he must live for his own sake, neither sacrificing himself to others nor sacrificing others to himself; he must work for his rational self-interest, with the achievement of his own happiness as the highest moral purpose of his life.”

“It's easy to run to others. It's so hard to stand on one's own record. You can fake virtue for an audience. You can't fake it in your own eyes. Your ego is your strictest judge. They run from it. They spend their lives running. It's easier to donate a few thousand to charity and think oneself noble than to base self-respect on personal standards of personal achievement. It's simple to seek substitutes for competence--such easy substitutes: love, charm, kindness, charity. But there is no substitute for competence.”

“Before you can do things for people, you must be the kind of man who can get things done. But to get things done, you must love the doing, not the secondary consequences. The work, not the people. Your own action, not any possible object of your charity.”

“Power-lust is a weed that grows only in the vacant lots of an abandoned mind. ”

“Have you ever looked for the root of production? Take a look at an electric generator and dare tell yourself that it was created by the muscular effort of unthinking brutes. Try to grow a seed of wheat without the knowledge left to you by men who had to discover it for the first time. Try to obtain your food by means of nothing but physical motions--and you'll learn that man's mind is the root of all the goods produced and of all the wealth that has ever existed on earth.”

“In order to live, man must act; in order to act, he must make choices; in order to make choices, he must define a code of values; in order to define a code of values, he must know what he is and where he is – i.e. he must know his own nature (including his means of knowledge) and the nature of the universe in which he acts – i.e. he needs metaphysics, epistemology, ethics, which means: philosophy. He cannot escape from this need; his only alternative is whether the philosophy guiding him is to be chosen by his mind or by chance.”
