Abstract: It has been argued powerfully by Alvin Plantinga that naturalism suffers a kind of epistemic self-refutation, for it cannot provide appropriately for the very possibility of its being accepted rationally and known to be true. This argument is explained carefully, and its merits assessed, by reference to the epistemology of apt belief and reflective knowledge.
