“The argument from design, therefore, can be sustained only with the help of a supposedly a priori double-barrelled principle, that mental order (at least in a god) is self-explanatory, but that all material order not only is not self-explanatory, but is positively improbable and in need of further explanation...this double-barrelled principle is recognizable as the core of the cosmological argument...The argument will not take us even as far as Kant seems to allow without borrowing the a priori thesis that there is a vicious metaphysical contingency in all natural things, and, in contrast with this, the 'transcendental' concept of a god who is self-explanatory and necessarily existent. It is only with the help of these borrowings that the design argument can introduce the required asymmetry, that any natural explanation uses data which call for further explanation, but that the theistic explanation terminates the regress. Without this asymmetry, the design argument cannot show that there is any need to go beyond the sort of hypothesis that Hume foreshadowed and that Wallace and Darwin supplied... The dependence of the argument for design on the ideas that are the core of the cosmological one is greater than Kant realized.”

“IDers argue that such traits, involving many parts that must cooperate for that trait to function at all, defy Darwinian explanation. Therefore, by default, they must have been designed by a supernatural agent. This is commonly called the "God of the gaps" argument, and it is an argument from ignorance. What it really says is that if we don't understand everything about how natural selection built a train, that lack of understanding itself is evidence for super-natural creation.”

“You all know the argument from design: everything in the world is made just so that we can manage to live in the world, and if the world was ever so little different, we could not manage to live in it. That is the argument from design. It sometimes takes a rather curious form; for instance, it is argued that rabbits have white tails in order to be easy to shoot. I do not know how rabbits would view that application.”

“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.”

“Family comes first" is indeed a powerful principle, but so is the imperative for your own development. It is not a self-explanatory or self-applying principle, and it can collide with other principles.”

“The argument for liberty is not an argument against organization, which is one of the most powerful tools human reason can employ, but an argument against all exclusive, privileged, monopolistic organization, against the use of coercion to prevent others from doing better.”
