“It must have been then that I began to lose faith in reasonable argument as the sole measure of truth.”

“I have always been faithful to you if faithful means the experience against which everything else has been measured.”

“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.”

“The medievals loved to say that God wrote two books: nature and Scripture. And since he is the author of both books, and since this Teacher never contradicts himself, these two books never contradict each other. And since this God who never contradicts himself also gave us the two truth detectors, faith and reason, it follows that faith and reason, properly used, never contradict each other. Therefore, all heresies are contrary to reason. Not all the truths of faith can be proved by reason, but all arguments against the truths of faith can be disproved by reason.”

“As soon as man began considering himself the source of the highest meaning in the world and the measure of everything, the world began to lose its human dimension, and man began to lose control of it.”

“There are things which must cause you to lose your reason or you have none to lose”
