Clive Staples Lewis, better known as C.S. Lewis, was a respected academic, writer, and speaker. While he might be best known for his works of fantasy, especially the Chronicles of Narnia and Space Trilogy series, he also wrote many books on Christian apologetics, including Mere Christianity, Miracles, and The Problem of Pain. While Lewis was a lecturer at Oxford, he became close friends with fellow lecturer J.R.R. Tolkien, future author of The Lord of the Rings trilogy. Bot
