"C. S. Lewis wrote that belief in Christianity was the only viable option if one thought honestly and rationally, and famously challenged nonbelievers by writing. "I am not asking anyone to accept Christianity if his best reasoning tells him the weight of the evidence is against it." Philosopher John Beversluis accepts Lewis's challenge in his new edition of C. S. Lewis and the Search for Rational Religion, subjecting each of Lewis's arguments for Christianity to the rigors of logical argument and finding them wanting. Beversluis also investigates C. S. Lewis's crisis of faith and asks whether Lewis lost his faith after the tragic death of his wife. Finally, he argues that Lewis's popularity is largely the result of his effective rhetorical style rather than the validity of his logical arguments."--BOOK JACKET.
