“Reason excludes faith," Alessandro responded, watching the blood-red mite as it made a dash for the rim. "It's deliberately limited. It won't function with the materials of religion. You can come close to proving the existence of God by reason, but you can't do it absolutely. That's because you can't do anything absolutely by reason. That's because reason depends on postulates. Postulates defy proof and yet they are essential to reason. God is a postulate. I don't think God is interested in the verification of His existence, and, therefore, neither am I. Anyway, I have professional reasons to believe. Nature and art pivot faithfully around God. Even dogs know that.”

“. . . you can't do anything absolutely by reason. That's because reason depends on postulates. Postulates defy proof and yet they are essential to reason.”

“You believe in entropy, which postulates that all phenomena tend to sink to lower levels of organization and energy, and in evolution, which postulates that the history of life has been just the opposite. People like you credit both theories. It’s de rigueur. Is that reason rational? I say, f*ck off.”

“You can't expect anyone to trust revelation if he hasn't experienced it himself. Those who haven't only know reason. And since revelation is a thing apart, and cannot be accounted for reasonably, they never will believe you. This is the great division of the world and always has been. When reason and revelation run together, why, then you have something great, a great age.”

“Every argument for God and every attribute ascribed to Him rests on a false metaphysical premise. None can survive for a moment on a correct metaphysics....Existence exists, and only existence exists. Existence is a primary: it is uncreated, indestructible, eternal. So if you are to postulate something beyond existence—some supernatural realm—you must do it by openly denying reason, dispensing with definitions, proofs, arguments, and saying flatly, “To Hell with argument, I have faith.” That, of course, is a willful rejection of reason.Objectivism advocates reason as man’s sole means of knowledge, and therefore, for the reasons I have already given, it is atheist. It denies any supernatural dimension presented as a contradiction of nature, of existence. This applies not only to God, but also to every variant of the supernatural ever advocated or to be advocated. In other words, we accept reality, and that’s all.”

“Guariglia went to his children, who were playing by the brazier. "Look at them," he said. "I know they may not be as beautiful to you as they are to me...""They are," Alessandro interrupted. "No," Guariglia insisted, "they're not beautiful in that way, but to me, Alessandro, they are all that is good and holy. I didn't know God until I saw them. It's funny, as soon as you lose faith, you have children, and life reawakens.”

“You can prove anything you want by coldly logical reason---if you pick the proper postulates.”
