Do You Believe in Demons?

“MY DEAR WORMWOOD, I wonder you should ask me whether it is essential to keep the patient in ignorance of your own existence. That question, at least for the present phase of the struggle, has been answered for us by the High Command. Our policy, for the moment, is to conceal ourselves. Of course this has not always been so. … But in the meantime we must obey our orders. I do not think you will have much difficulty in keeping the patient in the dark. The fact that "devils" are predominantly comic figures in the modern imagination will help you. If any faint suspicion of your existence begins to arise in his mind, suggest to him a picture of something in red tights, and persuade him that since he cannot believe in that (it is an old textbook method of confusing them) he therefore cannot believe in you.” - C.S. Lewis, The Screwtape Letters
