“Every form of happiness if one, every desire is driven by the same motor--by our love for a single value, for the highest potentiality of our own existence--and every achievement is an expression of it.”

“By the grace of reality and the nature of life, man–every man–is an end in himself, he exists for his own sake, and the achievement of his own happiness is his highest moral purpose”

“Love is our response to our highest values, and can be nothing else.”

“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.”

“Love should be treated like a business deal, but every business deal has its own terms and its own currency. And in love, the currency is virtue. You love people not for what you do for them or what they do for you. You love them for the values, the virtues, which they have achieved in their own character.”

“The course led them to the moment when, in answer to the highest of one's values, one's spirit makes one's body become the tribute, recasting it--as proof, as sanction, as reward--into a single sensation of such intensity of joy that no other sanction of one's existence is necessary.”

“Rules?" said Roark. "Here are my rules: what can be done with one substance must never be done with another. No two materials are alike. No two sites on earth are alike. No two buildings have the same purpose. The purpose, the site, the material determine the shape. Nothing can be reasonable or beautiful unless it's made by one central idea, and the idea sets every detail. A building is alive, like a man. Its integrity is to follow its own truth, its one single theme, and to serve its own single purpose. A man doesn't borrow pieces of his body. A building doesn't borrow hunks of its soul. Its maker gives it the soul and every wall, window and stairway to express it.”
