„Poverty, ignorance, illness and other problems of that kind are not metaphysical emergencies. By the metaphysical nature of man and of existence, man has to maintain his life by his own effort; the values he needs—such as wealth or knowledge—are not given to him automatically, as a gift of nature, but have to be discovered and achieved by his own thinking and work.“

— Ayn Rand

„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.“
— Ayn Rand
„I think the devil doesn't exist, but man has created him, he has created him in his own image and likeness.“

„A truly humble man is sensible of his natural distance from God; of his dependence on Him; of the insufficiency of his own power and wisdom; and that it is by God's power that he is upheld and provided for, and that he needs God's wisdom to lead and guide him, and His might to enable him to do what he ought to do for Him.“
— Jonathan Edwards
„I believe man suffers from an appalling ignorance of his own nature. I produce my own view in the belief that it may be something like the truth.“
— William Golding
„A man of knowledge lives by acting, not by thinking about acting… Thus a man of knowledge sweats and puffs and if one looks at him he is just like an ordinary man, except that the folly of his life is under his control.“
