Leonard Peikoff

“An individual can be hurt in countless ways by other men's irrationality, dishonesty, injustice. Above all, he can be disappointed, perhaps grievously, by the vices of a person he had once trusted or loved. But as long as his property is not expropriated and he remains unmolested physically, the damage he sustains is essentially spiritual, not physical; in such a case, the victim alone has the power and the responsibility of healing his wounds. He remains free: free to think, to learn from his experiences, to look elsewhere for human relationships; he remains free to start afresh and to pursue his happiness.”
― Leonard Peikoff, Objectivism: The Philosophy of Ayn Rand

“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.”
