C. S. Lewis continues to fascinate scholars and non-scholars alike. He was a scholar of abiding significance who was widely read, was highly knowledgeable, and did not hesitate to take positions that put him at odds with his contemporaries. He was also a writer of great skill, so that he was able to write not just works of great erudition but works of great popularity. Lewis is probably best remembered today for his The Chronicles of Narnia stories, but he also wrote science fiction and imaginative allegories and even poetry that merit attention. But Lewis probably continues to be as popular and widely read as he is because of his Christian faith that pervaded his life and as a result permeates the wide variety of writings that he left as a legacy. Lewis’s Christian faith was not easily gained and is not facilely understood. His was a complex faith born out of deep thinking about fundamental questions. His faith was also tested by significant human and spiritual challenges to which he responded, often outwardly and publicly in his writings. This volume addresses many of the issues surrounding Lewis through incisive essays on his theology, his fiction, and his scholarship.
