I found some relevant insights into our current political climate in Letter 7 of Screwtape Letters, a fictional correspondence between a senior level Demon (Uncle Screwtape) and his lower-level demon in training (Wormwood). C.S. Lewis wrote these in Great Britain during or just following World War II.
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. We are really faced with a cruel dilemma. When the humans disbelieve in our existence we lose all he pleasing results of direct terrorism and we make no magicians. On the other hand, when they believe in us, we cannot make them materialists and sceptics. At least, not yet …
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.
I had not forgotten my promise to consider whether we should make the patient an extreme patriot or an extreme pacifist. All extremes, except extreme devotion to the Enemy, are to be encouraged. Not always, of course, but at this period. Some ages are lukewarm and complacent, and then it is our business to soothe them yet faster asleep.
Other ages, of which the present is one, are unbalanced and prone to faction, and it is our business to inflame them. Any small coterie, bound together by some interest which other men dislike or ignore, tends to develop inside itself a hothouse of mutual admiration, and towards the outer world, a great deal of pride and hatred which is entertained without shame because the “Cause” is its sponsor and it is thought to be impersonal. Even when the little group exists originally for the Enemy’s [God’s] own purposes, this remains true …
Whichever he adopts, [patriotism or pacifism] your main task will be the same. Let him begin by treating the Patriotism or the Pacifism as a part of his religion. Then let him, under the influence of partisan spirit, come to regard it as the most important part. Then quietly and gradually nurse him on to the stage at which the religion becomes merely part of the “cause”, in which Christianity is valued chiefly because of the excellent arguments it can produce in favour of the British war-effort or of Pacifism.
The attitude which you want to guard against is that in which temporal affairs are treated primarily as material for obedience. Once you have made the World an end, and faith a means, you have almost won your man, and it makes very little difference what kind of worldly end he is pursuing. Provided that meetings, pamphlets, policies, movements, causes, and crusades, matter more to him than prayers and sacraments and charity, he is ours-and the more “religious” (on those terms) the more securely ours. I could show you a pretty cage full down here.
Your affectionate uncle
