Abstract

This article attempts to clarify an “argument from reason” set forth by C. S. Lewis in his Miracles. While there are various contemporary interpretations of the argument, Lewis intended to expose the “cardinal difficulty of naturalism.” First, this article seeks to clarify both Lewis’s argument and the understanding of naturalism that it presupposes. Second, philosophers of religion—especially, William Hasker and Alvin Plantinga—have significantly contributed to the argument’s contemporary discussion, and so their views are addressed with the intent to show how they differ from Lewis’s contribution. C. S. Lewis’s argument from reason was and is remains to this day philosophically timely and deserving of serious consideration.
