Is Naturalism Self-Defeating?
In a review of Richard Dawkin’s The God Delusion for Christianity Today, Notre Dame philosopher Alvin Plantinga argues that naturalism is “self-defeating and cannot rationally be believed.” If, as naturalists claim, there’s no god guiding the evolutionary process, then there’s no reason to think our cognitive faculties are reliable in giving us true beliefs about the world. Since we can’t trust our cognitive faculties, any conclusion we reach about the world is untrustworthy, including the claim that evolution is unguided. Therefore naturalism about evolution (and everything else) is self-defeating and must be given up. For us to trust our own beliefs (and we must, mustn’t we?) God must exist, and must have guided evolution.
