The Screwtape Letters: Letters from a Senior to a Junior Devil. C. S. Lewis

characteristics of a faction; but subordinate factions within her have often produced admirable results, from the parties of Paul and of Apollos at Corinth down to the High and Low parties in the Church of England.

      If your patient can be induced to become a conscientious objector he will automatically find himself one of a small, vocal, organised, and unpopular society, and the effects of this, on one so new to Christianity, will almost certainly be good. But only almost certainly. Has he had serious doubts about the lawfulness of serving in a just war before this present war began? Is he a man of great physical courage—so great that he will have no half-conscious misgivings about the real motives of his pacifism? Can he, when nearest to honesty (no human is ever very near), feel fully convinced that he is actuated wholly by the desire to obey the Enemy? If he is that sort of man, his pacifism will probably not do us much good, and the Enemy will probably protect him from the usual consequences of belonging to a sect. Your best plan, in that case, would be to attempt a sudden, confused, emotional crisis from which he might emerge as an uneasy convert to patriotism. Such things can often be managed. But if he is the man I take him to be, try Pacifism.

      Whichever he adopts, 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 cageful down here,

      My dear Wormwood,

      So you ‘have great hopes that the patient’s religious phase is dying away’, have you? I always thought the Training College had gone to pieces since they put old Slubgob at the head of it, and now I am sure. Has no one ever told you about the law of Undulation?

      Humans are amphibians—half spirit and half animal. (The Enemy’s determination to produce such a revolting hybrid was one of the things that determined Our Father to withdraw his support from Him.) As spirits they belong to the eternal world, but as animals they inhabit time. This means that while their spirit can be directed to an eternal object, their bodies, passions, and imaginations are in continual change, for to be in time means to change. Their nearest approach to constancy, therefore, is undulation—the repeated return to a level from which they repeatedly fall back, a series of troughs and peaks. If you had watched your patient carefully you would have seen this undulation in every department of his life—his interest in his work, his affection for his friends, his physical appetites, all go up and down. As long as he lives on earth periods of emotional and bodily richness and liveliness will alternate with periods of numbness and poverty. The dryness and dullness through which your patient is now going are not, as you fondly suppose, your workmanship; they are merely a natural phenomenon which will do us no good unless you make a good use of it.

      To decide what the best use of it is, you must ask what use the Enemy wants to make of it, and then do the opposite. Now it may surprise you to learn that in His efforts to get permanent possession of a soul, He relies on the troughs even more than on the peaks; some of His special favourites have gone through longer and deeper troughs than anyone else. The reason is this. To us a human is primarily food; our aim is the absorption of its will into ours, the increase of our own area of selfhood at its expense. But the obedience which the Enemy demands of men is quite a different thing. One must face the fact that all the talk about His love for men, and His service being perfect freedom, is not (as one would gladly believe) mere propaganda, but an appalling truth. He really does want to fill the universe with a lot of loathsome little replicas of Himself—creatures whose life, on its miniature scale, will be qualitatively like His own, not because He has absorbed them but because their wills freely conform to His. We want cattle who can finally become food; He wants servants who can finally become sons. We want to suck in, He wants to give out. We are empty and would be filled; He is full and flows over. Our war aim is a world in which Our Father Below has drawn all other beings into himself: the Enemy wants a world full of beings united to Him but still distinct.

      And that is where the troughs come in. You must have often wondered why the Enemy does not make more use of His power to be sensibly present to human souls in any degree He chooses and at any moment. But you now see that the Irresistible and the Indisputable are the two weapons which the very nature of His scheme forbids Him to use. Merely to override a human will (as His felt presence in any but the faintest and most mitigated degree would certainly do) would be for Him useless. He cannot ravish. He can only woo. For His ignoble idea is to eat the cake and have it; the creatures are to be one with Him, but yet themselves; merely to cancel them, or assimilate them, will not serve. He is prepared to do a little overriding at the beginning. He will set them off with communications of His presence which, though faint, seem great to them, with emotional sweetness, and easy conquest over temptation. But He never allows this state of affairs to last long. Sooner or later He withdraws, if not in fact, at least from their conscious experience, all those supports and incentives. He leaves the creature to stand up on its own legs—to carry out from the will alone duties which have lost all relish. It is during such trough periods, much more than during the peak periods, that it is growing into the sort of creature He wants it to be. Hence the prayers offered in the state of dryness are those which please Him best. We can drag our patients along by continual tempting, because we design them only for the table, and the more their will is interfered with the better. He cannot ‘tempt’ to virtue as we do to vice. He wants them to learn to walk and must therefore take away His hand; and if only the will to walk is really there He is pleased even with their stumbles. Do not be deceived, Wormwood. Our cause is never more in danger than when a human, no longer desiring, but still intending, to do our Enemy’s will, looks round upon a universe from which every trace of Him seems to have vanished, and asks why he has been forsaken, and still obeys.

      But of course the troughs afford opportunities to our side also. Next week I will give you some hints on how to exploit them,

      Your affectionate uncle

      My dear Wormwood,

      I hope my last letter has convinced you that the trough of dullness or ‘dryness’ through which your patient is going at present will not, of itself, give you his soul, but needs to be properly exploited. What forms the exploitation should take I will now consider.

      In the first place I have always found that the trough periods of the human undulation provide excellent opportunity for all sensual temptations, particularly those of sex. This may surprise you, because, of course, there is more physical energy, and therefore more potential appetite, at the peak periods; but you must remember that the powers of resistance are then also at their highest. The health and spirits which you want to use in producing lust can also, alas, be very easily used for work or play or thought or innocuous merriment. The attack has a much better chance of success when the man’s whole inner world is drab and cold and empty. And it is also to be noted that the trough sexuality is subtly different in quality from that of the peak—much less likely to lead to the milk and water phenomenon which the humans call ‘being in love’, much more easily drawn into perversions, much less contaminated by those generous and imaginative and even spiritual concomitants which often render human sexuality so disappointing. It is the same with other desires of the flesh. You
