"That a writer of Dr. Lewis's scholarly and literary stature should publish more than a dozen books directly or indirectly defending Christianity is news; that his works should have such wide repercussions is still more significant news and merits a second thought. What does it mean when his books become best-sellers? Does the fact indicate anything about the intellectual currents of the present decade? If so, it seems time to examine more closely the exact kind of Christianity and philosophy presented in Dr. Lewis's writings, and the literary techniques that have brought him into the forefront of authors dealing with religious themes."
"In this book I hope to add something (though not too much) to the scanty supply of biographical information available about Dr. Lewis, but my main concern will be with his ideas, the way he presents them, and the significance of his popularity. "
