“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.”

“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.”

“Because the beauty of the human body is that it hasn't a single muscle which doesn't serve its purpose; that there's not a line wasted; that every detail of it fits one idea, the idea of a man and the life of a man.”

“Every honest man lives for himself. Every man worth calling a man lives for himself. The one who doesn't - doesn't live at all.”

“Do you think integrity is the monopoly of the artist? And what, incidentally, do you think integrity is? The ability not to pick a watch out of your neighbor's pocket? No, it's not as easy as that. If that were all, I'd say ninety-five percent of humanity were honest, upright men. Only, as you can see, they aren't. Integrity is the ability to stand by an idea. That presupposes the ability to think. Thinking is something one doesn't borrow or pawn.”

“It's because...you see, if we had souls, which we haven't, and if our souls met--yours and mine--they'd fight to the death. But after they had torn each other to pieces, to the very bottom, they'd see that they had the same root.”

“They have taught man that he is a hopeless misfit made of two elements, both symbols of death. A body without a soul is a corpse, a soul without a body is a ghost- yet such is their image of man's nature: the battleground of a struggle between a corpse and a ghost, (john Galt)”
