“I don't build in order to have clients. I have clients in order to build!":”

“I told them that the form of a building must follow its function".”

“A building has integrity, just as a man and just as seldom! It must be true to its own idea, have its own form, and serve its own purpose!".”

“A building has integrity just like a man. And just as seldom.”

“If a drought strikes them, animals perish--man builds irrigation canals; if a flood strikes them, animals perish--man builds dams; if a carnivorous pack attacks them, animals perish--man writes the Constitution of the United States.”

“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.”
