“Really great moral teachers never do introduce new moralities: it is quacks and cranks who do that.... The real job of every moral teacher is to keep on bringing us back, time after time, to the old simple principles which we are all so anxious not to see; like bringing a horse back and back to the fence it has refused to jump or bringing a child back and back to the bit in its lesson that it wants to shirk.”

British author, literary scholar, and Anglican lay theologian

C. S. Lewis was a British author, literary scholar, and Anglican lay theologian. He held posts in English literature at Magdalen College, Oxford, and later at Magdalene College, Cambridge. He is best known for The Chronicles of Narnia. Lewis also wrote The Screwtape Letters and the Space Trilogy, along with Christian apologetic works such as Mere Christianity, Miracles, and The Problem of Pain. His writing ranges from imaginative fiction to religious argument, and much of it reflects his interest in Christian belief and moral questions.
