ient is in a light hypnotic trance, under the influence of certain drugs, or has been debilitated by illness, starvation, or any kind of physical or emotional stress. But what is true for suggestions above the threshold of consciousness is also true for suggestions beneath that threshold. In a word, the lower the level of a person's psychological resistance, the greater will be the effectiveness of strobonically injected suggestions. The scientific dictator of tomorrow will set up his whispering machines and subliminal projectors in schools and hospitals (children and the sick are highly suggestible), and in all public places where audiences can be given a preliminary softening up by suggestibility-increasing oratory or rituals.
From the conditions under which we may expect subliminal suggestion to be effective we now pass to the suggestions themselves. In what terms should the propagandist address himself to his victims' subconscious minds? Direct commands ("Buy popcorn" or "Vote for Jones") and unqualified statements ("Socialism stinks" or "X's toothpaste cures halitosis") are likely to take effect only upon those minds that are already partial to Jones and popcorn, already alive to the dangers of body odors and the public ownership of the means of production. But to strengthen existing faith is not enough; the propagandist, if he is worth his salt, must create new faith, must know how to bring the indifferent and the undecided over to his side, must be able to mollify and perhaps even convert the hostile. To subliminal assertion and command he knows that he must add subliminal persuasion.
Above the threshold of awareness, one of the most effective methods of non-rational persuasion is what may be called persuasion-by-association. The propagandist arbitrarily associates his chosen product, candidate or cause with some idea, some image of a person or thing which most people, in a given culture, unquestioningly regard as good. Thus, in a selling campaign female beauty may be arbitrarily associated with anything from a bulldozer to a diuretic; in a political campaign patriotism may be associated with any cause from apartheid to integration, and with any kind of person, from a Mahatma Gandhi to a Senator McCarthy. Years ago, in Central America, I observed an example of persuasion-by-association which filled me with an appalled admiration for the men who had devised it. In the mountains of Guatemala the only imported art works are the colored calendars distributed free of charge by the foreign companies whose products are sold to the Indians. The American calendars showed pictures of dogs, of landscapes, of young women in a state of partial nudity. But to the Indian, dogs are merely utilitarian objects, landscapes are what he sees only too much of, every day of his life, and half-naked blondes are uninteresting, perhaps a little repulsive. American calendars were, in consequence, far less popular than German calendars; for the German advertisers had taken the trouble to find out what the Indians valued and were interested in. I remember in particular one masterpiece of commercial propaganda. It was a calendar put out by a manufacturer of aspirin. At the bottom of the picture one saw the familiar trademark on the familiar bottle of white tablets. Above it were no snow scenes or autumnal woods, no cocker spaniels or bosomy chorus girls. No--the wily Germans had associated their pain-relievers with a brightly colored and extremely lifelike picture of the Holy Trinity sitting on a cumulus cloud and surrounded by St. Joseph, the Virgin Mary, assorted saints and a large number of angels. The miraculous virtues of acetyl salicylic acid were thus guaranteed, in the Indians' simple and deeply religious minds, by God the Father and the entire heavenly host.
This kind of persuasion-by-association is something to which the techniques of subliminal projection seem to lend themselves particularly well. In a series of experiments carried out at New York University, under the auspices of the National Institute of Health, it was found that a person's feelings about some consciously seen image could be modified by associating it, on the subconscious level, with another image, or, better still, with value-bearing words. Thus, when associated, on the subconscious level, with the word "happy," a blank expressionless face would seem to the observer to smile, to look friendly, amiable, outgoing. When the same face was associated, also on the subconscious level, with the word "angry," it took on a forbidding expression, and seemed to the observer to have become hostile and disagreeable. (To a group of young women, it also came to seem very masculine--whereas when it was associated with "happy," they saw the face as belonging to a member of their own sex. Fathers and husbands, please take note.) For the commercial and political propagandist, these findings, it is obvious, are highly significant. If he can put his victims into a state of abnormally high suggestibility, if he can show them, while they are in that state, the thing, the person or, through a symbol, the cause he has to sell, and if, on the subconscious level, he can associate this thing, person or symbol with some value-bearing word or image, he may be able to modify their feelings and opinions without their having any idea of what he is doing. It should be possible, according to an enterprising commercial group in New Orleans, to enhance the entertainment value of films and television plays by using this technique. People like to feel strong emotions and therefore enjoy tragedies, thrillers, murder mysteries and tales of passion. The dramatization of a fight or an embrace produces strong emotions in the spectators. It might produce even stronger emotions if it were associated, on the subconscious level, with appropriate words or symbols. For example, in the film version of A Farewell to Arms, the death of the heroine in childbirth might be made even more distressing than it already is by subliminally flashing upon the screen, again and again, during the playing of the scene, such ominous words as "pain," "blood" and "death." Consciously, the words would not be seen; but their effect upon the subconscious mind might be very great and these effects might powerfully reinforce the emotions evoked, on the conscious level, by the acting and the dialogue. If, as seems pretty certain, subliminal projection can consistently intensify the emotions felt by moviegoers, the motion picture industry may yet be saved from bankruptcy--that is, if the producers of television plays don't get there first.
In the light of what has been said about persuasion-by-association and the enhancement of emotions by subliminal suggestion, let us try to imagine what the political meeting of tomorrow will be like. The candidate (if there is still a question of candidates), or the appointed representative of the ruling oligarchy, will make his speech for all to hear. Meanwhile the tachistoscopes, the whispering and squeaking machines, the projectors of images so dim that only the subconscious mind can respond to them, will be reinforcing what he says by systematically associating the man and his cause with positively charged words and hallowed images, and by strobonically injecting negatively charged words and odious symbols whenever he mentions the enemies of the State or the Party. In the United State brief flashes of Abraham Lincoln and the words "government by the people" will be projected upon the rostrum. In Russia the speaker will, of course, be associated with glimpses of Lenin, with the words "people's democracy," with the prophetic beard of Father Marx. Because all this is still safely in the future, we can afford to smile. Ten or twenty years from now, it will probably seem a good deal less amusing. For what is now merely science fiction will have become everyday political fact.
Poetzl was one of the portents which, when writing Brave New World, I somehow overlooked. There is no reference in my fable to subliminal projection. It is a mistake of omission which, if I were to rewrite the book today, I should most certainly correct.

Hypnopaedia
In the late autumn of 1957 the Woodland Road Camp, a penal institution in Tulare County, California, became the scene of a curious and interesting experiment. Miniature loud-speakers were placed under the pillows of a group of prisoners who had volunteered to act as psychological guinea pigs. Each of these pillow speakers was hooked up to a phonograph in the Warden's office. Every hour throughout the night an inspirational whisper repeated a brief homily on "the principles of moral living." Waking at midnight, a prisoner might hear this still small voice extolling the cardinal virtues or murmuring, on behalf of his own Better Self, "I am filled with love and compassion for all, so help me God."
After reading about the Woodland Road Camp, I turned to the second chapter of Brave New World. In that chapter the Director of Hatcheries and Conditioning for Western Europe explains to a group of freshman conditioners and hatchers the workings of that state-controlled system of ethical education, known in the seventh century After Ford as hypnopaedia. The earliest attempts at sleep-teaching, the Director told his audience, had been misguided, and therefore unsuccessful. Educators had tried to give intellectual training to their slumbering pupils. But intellectual activity is incompatible with sleep. Hypnopaedia became successful only when it was used for moral training--in other words, for the conditioning of behavior through verbal suggestion at a time of lowered psychological resistance. "Wordless conditioning is crude and wholesale, cannot inculcate the more complex courses of behavior required by the State. For that there must be words, but words without reason" ... the kind of words that require no analysis for their comprehension, but can be swallowed whole by the sleeping brain. This is true hypnopaedia, "the greatest moralizing and socializing force of all time." In the Brave New World, no citizens belonging to the lower castes ever gave any trouble. Why? Because, from the moment he could speak and understand what was said to him, every lower-caste child was exposed to endlessly repeated suggestions, night after night, during the hours of drowsiness and sleep. These suggestions were "like drops of liquid sealing wax, drops that adhere, incrust, incorporate themselves with what they fall on, till finally the rock is all one scarlet blob. Till at last the child's mind is these suggestions and the sum of these suggestions is the child's mind. And not the child's mind only. The adult's mind too--all his life long. The mind that judges and desires and decides--made up of these suggestions. But these suggestions are our suggestions--suggestions from the State...."
To date, so far as I know, hypnopaedic suggestions have been given by no state more formidable than Tulare County, and the nature of Tulare's hypnopaedic suggestions to lawbreakers is unexceptionable. If only all of us, and not only the inmates of the Woodland Road Camp, could be effectively filled, during our sleep, with love and compassion for all! No, it is not the message conveyed by the inspirational whisper that one objects to; it is the principle of sleep teaching by governmental agencies. Is hypnopaedia the sort of instrument that officials, delegated to exercise authority in a democratic society, ought to be allowed to use at their discretion? In the present instance they are using it only on volunteers and with the best intentions. But there is no guarantee that in other cases the intentions will be good or the indoctrination on a voluntary basis. Any law or social arrangement which makes it possible for officials to be led into temptation is bad. Any law or arrangement which preserves them from being tempted to abuse their delegated power for their own advantage, or for the benefit of the State or of some political, economic or ecclesiastical organization, is good. Hypnopaedia, if it is effective, would be a tremendously powerful instrument in the hands of anyone in a position to impose suggestions upon a captive audience. A democratic society is a society dedicated to the proposition that power is often abused and should therefore be entrusted to officials only in limited amounts and for limited periods of time. In such a society, the use of hypnopaedia by officials should be regulated by law--that is, of course, if hypnopaedia is genuinely an instrument of power. But is it in fact an instrument of power? Will it work now as well as I imagined it working in the seventh century A.F.? Let us examine the evidence.
In the Psychological Bulletin for July, 1955, Charles W. Simon and William H. Emmons have analyzed and evaluated the ten most important studies in the field. All these studies were concerned with memory. Does sleep-teaching help the pupil in his task of learning by rote? And to what extent is material whispered into the ear of a sleeping person remembered next morning when he wakes? Simon and Emmons answer as follows: "Ten sleep-learning studies were reviewed. Many of these have been cited uncritically by commercial firms or in popular magazines and news articles as evidence in support of the feasibility of learning during sleep. A critical analysis was made of their experimental design, statistics, methodology and criteria of sleep. All the studies had weaknesses in one or more of these areas. The studies do not make it unequivocally clear that learning during sleep actually takes place. But some learning appears to take place in a special kind of waking state wherein the subjects do not remember later on if they had been awake. This may be of great practical importance from the standpoint of economy in study time, but it cannot be construed as sleep learning.... The problem is partially confounded by an inadequate definition of sleep."
Meanwhile the fact remains that in the American Army during the Second World War (and even, experimentally, during the First) daytime instructions in the Morse Code and in foreign languages was supplemented by instruction during sleep--apparently with satisfactory results. Since the end of World War II several commercial firms in the United States and elsewhere have sold large numbers of pillow speakers and clock-controlled phonographs and tape recorders for the use of actors in a hurry to learn their parts, of politicians and preachers who want to give the illusion of being extemporaneously eloquent, of students preparing for examinations and, finally and most profitably, of the countless people who are dissatisfied with themselves as they are and would like to be suggested or autosuggested into becoming something else. Self-administered suggestion can easily be recorded on magnetic tape and listened to, over and over again, by day and during sleep. Suggestions from the outside may be bought in the form of records carrying a wide variety of helpful messages. There are on the market records for the release of tension and the induction of deep relaxation, records for promoting self-confidence (much used by salesmen), records for increasing one's charm and making one's personality more magnetic. Among the best sellers are records for the achievement of sexual harmony and records for those who wish to lose weight. ("I am cold to chocolate, insensible to the lure of potatoes, utterly unmoved by muffins.") There are records for improved health and even records for making more money. And the remarkable thing is that, according to the unsolicited testimonials sent in by grateful purchasers of these records, many people actually do make more money after listening to hypnopaedic suggestions to that effect, many obese ladies do lose weight and many couples on the verge of divorce achieve sexual harmony and live happily ever after.
In this context an article by Theodore X. Barber, "Sleep and Hypnosis," which appeared in The Journal of Clinical and Experimental Hypnosis for October, 1956, is most enlightening. Mr. Barber points out that there is a significant difference between light sleep and deep sleep. In deep sleep the electroencephalograph records no alpha waves; in light sleep alpha waves make their appearance. In this respect light sleep is closer to the waking and hypnotic states (in both of which alpha waves are present) than it is to deep sleep. A loud noise will cause a person in deep sleep to awaken. A less violent stimulus will not arouse him, but will cause the reappearance of alpha waves. Deep sleep has given place for the time being to light sleep.
A person in deep sleep is unsuggestible. But when subjects in light sleep are given suggestions, they will respond to them, Mr. Barber found, in the same way that they respond to suggestions when in the hypnotic trance.
Many of the earlier investigators of hypnotism made similar experiments. In his classical History, Practice and Theory of Hypnotism, first published in 1903, Milne Bramwell records that "many authorities claim to have changed natural sleep into hypnotic sleep. According to Wetterstrand, it is often very easy to put oneself en rapport with sleeping persons, especially children.... Wetterstrand thinks this method of inducing hypnosis of much practical value and claims to have often used it successfully." Bramwell cites many other experienced hypnotists (including such eminent authorities as Bernheim, Moll and Forel) to the same effect. Today an experimenter would not speak of "changing natural into hypnotic sleep." All he is prepared to say is that light sleep (as opposed to deep sleep without alpha waves) is a state in which many subjects will accept suggestions as readily as they do when under hypnosis. For example, after being told, when lightly asleep, that they will wake up in a little while, feeling extremely thirsty, many subjects will duly wake up with a dry throat and a craving for water. The cortex may be too inactive to think straight; but it is alert enough to respond to suggestions and to pass them on to the autonomic nervous system.
As we have already seen, the well-known Swedish physician and experimenter, Wetterstrand, was especially successful in the hypnotic treatment of sleeping children. In our own day Wetterstrand's methods are followed by a number of pediatricians, who instruct young mothers in the art of giving helpful suggestions to their children during the hours of light sleep. By this kind of hypnopaedia children can be cured of bed wetting and nail biting, can be prepared to go into surgery without apprehension, can be given confidence and reassurance when, for any reason, the circumstances of their life have become distressing. I myself have seen remarkable results achieved by the therapeutic sleep-teaching of small children. Comparable results could probably be achieved with many adults.
For a would-be dictator, the moral of all this is plain. Under proper conditions, hypnopaedia actually works--works, it would seem, about as well as hypnosis. Most of the things that can be done with and to a person in hypnotic trance can be done with and to a person in light sleep. Verbal suggestions can be passed through the somnolent cortext to the midbrain, the brain stem and the autonomic nervous system. If these suggestions are well conceived and frequently repeated, the bodily functions of the sleeper can be improved or interfered with, new patterns of feeling can be installed and old ones modified, posthypnotic commands can be given, slogans, formulas and trigger words deeply ingrained in the memory. Children are bet
