If one book can be said to have introduced C. S. Lewis to the world on a wide scale, it would be The Screwtape Letters. They are witty and full of insight, as a senior devil gives advice to a junior devil on how to tempt his human into disobedience to God—who was termed “the Enemy” in the book.
Lewis, though, says it was the hardest book he ever wrote, and I can understand why. He explained it this way:
Of all my books, there was only one I did not take pleasure in writing. . . . The Screwtape Letters. They were dry and gritty going. At the time, I was thinking of objections to the Christian life, and decided to put them into the form, “That’s what the devil would say.” But making goods “bad” and bads “good” gets to be fatiguing.
Although he vowed never to repeat that exercise, he did, later, write another little treatise that is now commonly included in newer editions of Screwtape. He imagined Screwtape giving a speech at the “Annual Dinner of the Tempters’ Training College for Young Devils” and called it “Screwtape Proposes a Toast.” In it, it’s obvious he still had the flair that produced the original. Take, for instance, Screwtape’s gloating on how mankind’s real enemy has subverted man’s desire for liberty:
Hidden in the heart of this striving for Liberty there was also a deep hatred of personal freedom. That invaluable man Rousseau first revealed it. In his perfect democracy, you remember, only the state religion is permitted, slavery is restored, and the individual is told that he has really willed (though he didn’t know it) whatever the Government tells him to do. From that starting point, via Hegel (another indispensable propagandist on our side) we easily contrived both the Nazi and the Communist state.
If you’ve never given The Screwtape Letters a try, why not now? Valuable insights await.
