“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.”

“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.”

“Creationists eagerly seek a gap in present-day knowledge or understanding. If an apparent gap is found, it is assumed that God, by default, must fill it.”

“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.”

“To understand an issue or someone’s argument about anything,one needs to understand the very nature of the issue, which is thefoundational question concerning anything.”

“Selection is both revolutionary and disturbing for the same reason: it explains apparent design in nature by a purely materialistic process that doesn't require creation or guidance by supernatural forces.”
