C. S. Lewis' argument from reason is perhaps his most famous argument because of the legendary debate that it inspired. In a response to it at Oxford University's Socratic Club, G. E. M. Anscombe reputedly demolished the argument, causing Lewis to withdraw from contributing to apologetics ever again. Many disagree that Anscombe actually demolished Lewis' central point, but grant that the encounter destroyed Lewis' confidence as a philosopher. In this paper (originally presented as a talk) David Kyle Johnson argues that Lewis' encounter with Anscombe should have reduced his confidence as an apologist because his argument rests on an embarrassing fundamental misunderstanding. In particular, after outlining the exchange between Lewis and Anscombe, Johnson aims to show that Lewis severely misunderstood both naturalism and evolution, and that this misunderstanding permeated Lewis' argument from reason.
In this article David Kyle Johnson argues that both the diversity of religious experiences and natural explanations for them entail that religious experiences cannot provide justification for religious beliefs. Johnson first considers the supposed role of religious experiences in justifying religious belief, then shows how the diversity of religious experiences raises an inductive problem that negates the ability of religious experience to justify religious belief. Finally, he shows that available natural explanations for religious experiences have the same end result by providing better explanations of religious experiences than religious explanations of them.
