C.S. Lewis, in his book "Screwtape Letters" pictures an experienced demon (Screwtape) mentoring his nephew, Wormwood, in how to be an effective demon... He does this through writing letters... this one on how to keep a new Christian from following “The Enemy” (who for demons is the living God).
“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 the High Command. Our policy, for the moment, is to conceal ourselves…. I do not think you will have much difficulty in keeping the patient in the dark. The fact that ‘devils’ are 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.”
In The Problem with Pain, C.S. Lewis states that people will “enjoy forever the horrible freedom they have demanded, and are therefore self-enslaved.”
