Yet even at this remarkably early stage H. was found to be in some degree receptive to certain Suggestions conveyed by repeated stimulation under uniform conditions. In the first place, the suggestions of sleep began to tell upon her before the end of the first month. Her nurse put her to sleep by laying her face down and patting gently upon the end of her spine. This position soon became itself not only suggestive to the child of sleep, but sometimes necessary to sleep, even when she was laid across the nurse's lap in what seemed to be an uncomfortable position.

This case ill.u.s.trates what may be called Physiological Suggestion. It shows the law of physiological habit as it borders on the conscious.

The same sort of phenomena appear also in adult life. Positions given to the limbs of a sleeper lead to movements ordinarily a.s.sociated with these positions. The sleeper defends himself, withdraws himself from cold, etc. Children learn gradually to react upon conditions of position, lack of support, etc., of the body, with those actions necessary to keep from falling, which adults have so perfectly. All secondary automatic reactions may be cla.s.sed here; the sensations coming from one action, as in walking, being suggestions to the next movement, unconsciously acted upon. The consciousness at any stage in the chain of movements, if present at all, must be similar to the baby's in the case above--a mere internal glimmering. The most we can say of such physiological suggestion is, that there is probably some consciousness, and that the ordinary reflexes seem to be abbreviated and improved.

_Subconscious Adult Suggestion._--There are certain phenomena of a rather striking kind coming under this head whose cla.s.sification is so evident that we may enumerate them without discussion of the general principles which they involve.

_Tune Suggestion._--It has been pointed out recently that dream states are largely indebted for their visual elements--what we see in our dreams--to accidental lines, patches, etc., in the field of vision when the eyes are shut, due to the distended blood vessels of the cornea and lids, to changes in the external illumination, to the presence of dust particles of different configuration, etc. The other senses also undoubtedly contribute to the texture of our dreams by equally subconscious suggestions. There is no doubt, further, that our waking life is constantly influenced by such trivial stimulations.

I have tested in detail, for example, the conditions of the rise of so-called "internal tunes"--we speak of "tunes in our head" or "in our ears"--and find certain suggestive influences which in most cases cause these tunes to rise and take their course. Often, when a tune springs up "in my head," the same tune has been lately sung or whistled in my hearing, though quite unnoticed at the time. Often the tunes are those heard in church the previous day or earlier. Such a tune I am entirely unable to recall voluntarily; yet when it comes into the mind's ear, so to speak, I readily recognise it as belonging to an earlier day's experience. Other cases show various accidental suggestions, such as the tune Mozart suggested by the composer's name, the tune Gentle Annie suggested by the name Annie, etc. In all these cases it is only after the tune has taken possession of consciousness and after much seeking that the suggesting influence is discovered.

Closer a.n.a.lysis reveals certain additional facts: The "time" of such internal tunes is usually dictated by some rhythmical subconscious occurrence. After hearty meals it is always the time of the heart beat, unless there be "in the air" some more impressive stimulus; as, for example, when on shipboard, the beat is with me invariably that of the engine throbs. When walking it is the rhythm of the footfall. On one occasion a knock of four beats on the door started the Ma.r.s.eillaise in my ear; following up this clew, I found that at any time different divisions of musical time being struck on the table at will by another person, tunes would spring up and run on, getting their cue from the measures suggested. Further, when a tune dies away, its last notes often suggest, some time after, another having a similar movement--just as we pa.s.s from one tune to another in a "medley." It may also be noted that in my case the tune memories are auditive: they run in my head when I have no words for them and have never sung them--an experience which is consistent with the fact that these "internal tunes" arise in childhood before the faculty of speech. They also have distinct pitch. For example, I once found a tune "in my head" which was perfectly familiar, but for which I could find no words. Tested on the piano, the pitch was F-sharp and the time was my heart beat. Finally, after much effort, I got the unworthy words "Wait till the clouds roll by" by humming the tune over repeatedly. The pitch is determined probably by the accidental condition of the auditory centre in the brain or by the pitch of the external sound which serves as stimulus to the tune.

_Normal Auto-Suggestion._--A further cla.s.s of Suggestions, which fall under the general phrase Auto-suggestion, or Self-suggestion of a normal type, may be ill.u.s.trated. In experimenting upon the possibility of suggesting sleep to another I have found certain strong reactive influences upon my own mental condition. Such an effort, which involves the picturing of another as asleep, is a strong Auto-suggestion of sleep, taking effect in my own case in about five minutes if the conditions be kept constant. The more clearly the patient's sleep is pictured the stronger becomes the subjective feeling of drowsiness. After about ten minutes the ability to give strong concentration seems to disintegrate, attention is renewed only by fits and starts and in the presence of great, mental inertia, and the oncoming of sleep is almost overpowering. An unfailing cure for insomnia, speaking for myself, is the persistent effort to put some one else asleep by hard thinking of the end in view, with a continued gentle movement, such as stroking the other with the hand.

On the other hand, it is impossible to bring on a state of drowsiness by imagining myself asleep. The first effort at this, indeed, is promising, for it leads to a state of restfulness and ease akin to the mental composure which is the usual preliminary to sleep; but it goes no further. It is succeeded by a state of steady wakefulness, which effort of attention or effort not to attend only intensifies. If the victim of insomnia could only forget that he is thus afflicted, could forget himself altogether, his case would be more hopeful. The contrast between this condition and that already described shows that it is the Self-idea, with the emotions it awakens,[11] which prevents the suggestion from realizing itself and probably accounts for many cases of insomnia.

[Footnote 11: A friend informs me that when he pictures himself dead he can not help feeling gratified that he makes so handsome a corpse.]

_Sense Exaltation._--Recent discussions of Hypnotism have shown the remarkable "exaltation" which the senses may attain in somnambulism, together with a corresponding refinement in the interpretative faculty. This is described more fully below. Events, etc., quite subconscious, usually become suggestions of direct influence upon the subject. Unintended gestures, habitual with the experimenter, may suffice to hypnotize his accustomed subject. The possibility of such training of the senses in the normal state has not had sufficient emphasis. The young child's subtle discriminations of facial and other personal indications are remarkable. The prolonged experience of putting H. to sleep--extending over a period of more than six months, during which I slept beside her bed--served to make me alive to a certain cla.s.s of suggestions otherwise quite beyond notice. It is well known that mothers are awake to the needs of their infants when they are asleep to everything else.

In the first place, we may note the intense auto-suggestion of sleep already pointed out, under the stimulus of repeated nursery rhymes or other regular devices regularly resorted to in putting the child asleep. Second, surprising progressive exaltation of the hearing and interpretation of sounds coming from her in a dark room. At the end of four or five months, her movements in bed awoke me or not according as she herself was awake or not. Frequently after awaking I was distinctly aware of what movements of hers had awaked me.[12] A movement of her head by which it was held up from the pillow was readily distinguished from the restless movements of her sleep. It was not so much, therefore, exaltation of hearing as exaltation of the function of the recognition of sounds heard and of their discrimination.

[Footnote 12: This fact is a.n.a.logous to our common experience of being awaked by a loud noise and then hearing it after we awake; yet the explanation is not the same.]

Again, the same phenomenon to an equally marked degree attended the sound of her breathing. It is well enough known that the smallest functional bodily changes induce changes in both the rapidity and the quality of the respiration. In sleep the muscles of inhalation and exhalation are relaxed, inhalation becomes long and deep, exhalation short and exhaustive, and the rhythmic intervals of respiration much lengthened. Now degrees of relative wakefulness are indicated with surprising delicacy by the slight respiration sounds given forth by the sleeper. Professional nurses learn to interpret these indications with great skill. This exaltation of hearing became very p.r.o.nounced in my operations with the child. After some experience the peculiar breathing of advancing or actual wakefulness in her was sufficient to wake me. And when awake myself the change in the infant's respiration sounds to those indicative of oncoming sleep was sufficient to suggest or bring on sleep in myself. In the dark, also, the general character of her breathing sounds was interpreted with great accuracy in terms of her varied needs, her comfort or discomfort, etc. The same kind of suggestion from the respiration sounds now troubles me whenever one of the children is sleeping within hearing distance.[13]

[Footnote 13: This is an unpleasant result which is confirmed by professional infants' nurses. They complain of loss of sleep when off duty. Mrs. James Murray, an infants' nurse in Toronto, informs me that she finds it impossible to sleep when she has no infant in hearing distance, and for that reason she never asks for a vacation.

Her normal sleep has evidently come to depend upon continuous soporific suggestions from a child. In another point, also, her experience confirms my observations, viz., the child's movements, preliminary to waking, awake her, when no other movements of the child do so--the consequence being that she is ready for the infant when it gets fully awake and cries out.]

The reactions in movement upon these suggestions are very marked and appropriate, in customary or habitual lines, although the stimulations are quite subconscious. The clearest ill.u.s.trations in this body of my experiences were afforded by my responses in crude songs to the infant's waking movements and breathing sounds. I have often waked myself by myself singing one of two nursery rhymes, which by endless repet.i.tion night after night had become so habitual as to follow in an automatic way upon the stimulus from the child. It is certainly astonishing that among the things which one may get to do automatically, we should find singing; but writers on the subject have claimed that the function of musical or semi-musical expression may be reflex.

The principle of subconscious suggestion, of which these simple facts are less important ill.u.s.trations, has very interesting applications in the higher reaches of social, moral, and educational theory.

_Inhibitory Suggestion._--An interesting cla.s.s of phenomena which figure perhaps at all the levels of nervous action now described, may be known as Inhibitory Suggestions. The phrase, in its broadest use, refers to all cases in which the suggesting stimulus tends to suppress, check, or inhibit movement. We find this in certain cases just as strongly marked as the positive movement--bringing kind of suggestion. The facts may be put under certain heads which follow.

_Pain Suggestion._--Of course, the fact that pain inhibits movement occurs at once to the reader. So far as this is general, and is a native inherited thing, it is organic, and so falls under the head of Physiological Suggestion of a negative sort. The child shows contracting movements, crying movements, starting and jumping movements, shortly after birth, and so plainly that we need not hesitate to say that these pain responses belong purely to his nervous system; and that, in general, they are inhibitory and contrary to those other native reactions which indicate pleasure.

The influence of pain extends everywhere through mental development, however. Its general effect is to dampen down or suppress the function which brings the pain; and in this its action is just the contrary to that of pleasure, which furthers the pleasurable function.

_Control Suggestion._--This covers all cases which show any kind of restraint set upon the movements of the body short of that which comes from voluntary intention. The infant brings the movements of his legs, arms, head, etc., gradually into some sort of order and system. It is accomplished by a system of organic checks and counter-checks, by which a.s.sociations are formed between muscular sensations on the one hand and certain other sensations, as of sight, touch, hearing, etc., on the other hand. The latter serve as suggestions to the performance of these movements, and these alone. The infant learns to balance his head and trunk, to direct his hands, to grasp with thumb opposite the four fingers--all largely by such control suggestions, aided, of course, by his native reflexes.

_Contrary Suggestion._--By this is meant a tendency of a very striking kind observable in many children, no less than in many adults, to do the contrary when any course is suggested. The very word "contrary" is used in popular talk to describe an individual who shows this type of conduct. Such a child or man is rebellious whenever rebellion is possible; he seems to kick const.i.tutionally against the p.r.i.c.ks.

The fact of "contrariness" in older children--especially boys--is so familiar to all who have observed school children with any care that I need not cite further details. And men and women often become so enslaved to suggestions of the contrary that they seem only to wait for indications of the wishes of others in order to oppose and thwart them.

Contrary suggestions are to be explained as exaggerated instances of control. It is easy to see that the checks and counter-checks already spoken of as const.i.tuting the method of control of muscular movement may themselves become so habitual and intense as to dominate the reactions which they should only regulate. The a.s.sociations between the muscular series and the visual series, let us say, which controls it, comes to work backward, so that the drift of the organic processes is toward certain contrary reverse movements.

In the higher reaches of conduct and life we find interesting cases of very refined contrary suggestion. In the man of ascetic temperament, the duty of self-denial takes the form of a regular contrary suggestion in opposition to every invitation to self-indulgence, however innocent. The over-scrupulous mind, like the over-precise, is a prey to the eternal remonstrances from the contrary which intrude their advice into all his decisions. In matters of thought and belief also cases are common of stubborn opposition to evidence, and persistence in opinion, which are in no way due to the cogency of the contrary arguments or to real force of conviction.

_Hypnotic Suggestion._--The facts upon which the current theories of hypnotism are based may be summed up under a few headings, and the recital of them will serve to bring this cla.s.s of phenomena into the general lines of cla.s.sification drawn out in this chapter.

_The Facts._--When by any cause the attention is held fixed upon an object, say a bright b.u.t.ton, for a sufficient time without distraction, the subject begins to lose consciousness in a peculiar way. Generalizing this simple experiment, we may say that any method or device which serves to secure undivided and prolonged attention to any sort of Suggestion--be it object, idea, anything that is clear and striking--brings on what is called Hypnosis to a person normally const.i.tuted.

The Paris school of interpreters find three stages of progress in the hypnotic sleep: First, Catalepsy, characterized by rigid fixity of the muscles in any position in which the limbs may be put by the experimenter, with great Suggestibility on the side of consciousness, and Anaesthesia (lack of sensation) in certain areas of the skin and in certain of the special senses; second, Lethargy, in which consciousness seems to disappear entirely; the subject not being sensitive to any stimulations by eye, ear, skin, etc., and the body being flabby and pliable as in natural sleep; third, Somnambulism, so called from its a.n.a.logies to the ordinary sleep-walking condition to which many persons are subject. This last covers the phenomena of ordinary mesmeric exhibitions at which travelling mesmerists "control"

persons before audiences and make them obey their commands. While other scientists properly deny that these three stages are really distinct, they may yet be taken as representing extreme instances of the phenomena, and serve as points of departure for further description.

On the mental side the general characteristics of hypnotic Somnambulism are as follows:

1. _The impairment of memory_ in a peculiar way. In the hypnotic condition all affairs of the ordinary life are forgotten; on the other hand, after waking the events of the hypnotic condition are forgotten.

Further, in any subsequent period of Hypnosis the events of the former similar periods are remembered. So a person who is frequently hypnotized has two continuous memories: one for the events of his normal life, exercised only when he is normal; and one for the events of his hypnotic periods, exercised only when he is hypnotized.

2. _Suggestibility_ to a remarkable degree. By this is meant the tendency of the subject to have in reality any mental condition which is suggested to him. He is subject to Suggestions both on the side of his sensations and ideas and also on the side of his actions. He will see, hear, remember, believe, refuse to see, hear, etc., anything, with some doubtful exceptions, which may be suggested to him by word or deed, or even by the slightest and perhaps unconscious indications of those about him. On the side of conduct his suggestibility is equally remarkable. Not only will he act in harmony with the illusions of sight, etc., into which he is led, but he will carry out, like an automaton, the actions suggested to him. Further, pain and pleasure, with their organic accompaniments may be produced by Suggestion. The skin may be actually scarred with a lead pencil if the patient be told that it is red-hot iron. The suggested pain brings about vasomotor and other bodily changes that prove, as similar tests in the other cases prove, that simulation is impossible and the phenomena are real. These truths and those given below are no longer based on the mere reports of the "mesmerists," but are the recognised property of legitimate psychology.

Again, such suggestions may be for a future time, and be performed only when a suggested interval has elapsed; they are then called Deferred or Post-hypnotic Suggestions. Post-hypnotic Suggestions are those which include the command not to perform them until a certain time after the subject has returned to his normal condition; such suggestions--if of reasonably trifling character--are actually carried out afterward in the normal state, although the person is conscious of no reason why he should act in such a way, having no remembrance whatever that he has received the suggestion when hypnotized. Such post-hypnotic performances may be deferred by suggestion for many months.

3. So-called _Exaltation_ of the mental faculties, especially of the senses: increased acuteness of vision, hearing, touch, memory, and the mental functions generally. By reason of this great "exaltation,"

hypnotized patients may get suggestions from the experimenters which are not intended, and discover their intentions when every effort is made to conceal them. Often emotional changes in expression are discerned by them; and if it be admitted that their power of logical and imaginative insight is correspondingly exalted, there is hardly a limit to the patient's ability to read, simply from physical indications, the mental states of those who experiment with him.

4. So-called _Rapport_. This term covers all the facts known, before the subject was scientifically investigated, by such expressions as "personal magnetism," "will power over the subject", etc. It is true that one particular operator alone may be able to hypnotize a particular patient; and in this case the patient is, when hypnotized, open to suggestions from that person only. He is deaf and blind to everything enjoined by anyone else. It is easy to see from what has already been said that this does not involve any occult nerve influence or mental power. A sensitive patient anybody can hypnotize, provided only that the patient have the idea or conviction that the experimenter possesses such power. Now, let a patient get the idea that only one man can hypnotize him, and that is the beginning of the hypnotic suggestion itself. It is a part of the suggestion that a certain personal _Rapport_ is necessary; so the patient must have this _Rapport_. This is shown by the fact that when such a patient is hypnotized, the operator _en rapport_ with him can transfer the so-called control to any one else simply by suggesting to the patient that this third party can also hypnotize him. _Rapport_, therefore, and all the amazing claims of charlatans to powers of charming, stealing another's personality, controlling his will at a distance--all such claims are explained, so far as they have anything to rest upon, by suggestion under conditions of mental hyperaesthesia or exaltation.

I may now add certain practical remarks on the subject.

In general, any method which fixes the attention upon a single stimulus long enough is probably sufficient to produce Hypnosis; but the result is quick and profound in proportion as the patient has the idea that it is going to succeed, i. e., gets the suggestion of sleep. It may be said, therefore, that the elaborate performances, such as pa.s.ses, rubbings, mysterious incantations, etc., often resorted to, have no physiological effect whatever, and only serve to work in the way of suggestion upon the mind of the subject. In view of this it is probable that any person in normal health can be hypnotized, provided he is not too sceptical of the operator's knowledge and power; and, on the contrary, any one can hypnotize another, provided he do not arouse too great scepticism, and is not himself wavering and clumsy. It is probable, however, that susceptibility varies greatly in degree, and that race exerts an important influence. Thus in Europe the French seem to be most susceptible, and the English and Scandinavians least so. The impression that weak-minded persons are most available is quite mistaken. On the contrary, patients in the insane asylums, idiots, etc., are the most refractory. This is to be expected, from the fact that in these cases power of strong, steady attention is wanting. The only cla.s.s of pathological cases which seem peculiarly open to the hypnotic influence is that of the hystero-epileptics, whose tendencies are toward extreme suggestibility.

Further, one may hypnotize himself--what we have called above Auto-suggestion--especially after having been put into the trance more than once by others. When let alone after being hypnotized, the patient usually pa.s.ses into a normal sleep and wakes naturally.

It is further evident that frequent hypnotization is very damaging if done by the same operator, since then the patient contracts a habit of responding to the same cla.s.s of suggestions; and this may influence his normal life. A further danger arises from the possibility that all suggestions have not been removed from the patient's mind before his awaking. Competent scientific observers always make it a point to do this. It is possible also that damaging effects result directly to a man from frequent hypnotizing; and this is in some degree probable, simply from the fact that, while it lasts, the state is abnormal.

Consequently, all general exhibitions in public, as well as all individual hypnotizing by amateurs, should be prohibited by law, and the whole practical application as well as observation of Hypnosis should be left in the hands of physicians or experts who have proved their fitness by an examination and secured a certificate of licence.

In Russia a decree (summer, 1893) permits physicians to practise hypnotism for purposes of cure under official certificates. In France public exhibitions are forbidden.

So-called Criminal Suggestions may be made, with more or less effect, in the hypnotic state. Cases have been tried in the French courts, in which evidence for and against such influence of a third person over the criminal has been admitted. The reality of the phenomenon, however, is in dispute. The Paris school claim that criminal acts may be suggested to the hypnotized subject, which are just as certain to be performed by him as any other acts. Such a subject will discharge a blank-loaded pistol at one, when told to do so, or stab him with a paper dagger. While admitting the facts, the Nancy theorists claim that the subject knows the performance to be a farce; gets suggestions of the unreality of it from the experimenters, and so acquiesces. This is probably true, as is seen in frequent cases in which patients have refused, in hypnotic sleep, to perform suggested acts which shocked their modesty, veracity, etc. This goes to show that the Nancy school are right in saying that while in Hypnosis suggestibility is exaggerated to an enormous degree, still it has limits in the more well-knit habits, moral sentiments, social opinions, etc., of the subject. And it further shows that Hypnosis is probably, as they claim, a temporary disturbance, rather than a pathological condition of mind or body.

There have been many remarkable and sensational cases of cure of disease by hypnotic suggestion, reported especially in France. That hysteria in many of its manifestations has been relieved is certainly true; but that any organic, structural disease has ever been cured by hypnotism is unproved. It is not regarded by medical authorities as an agent of much therapeutic value, and is rarely employed; but it is doubtful, in view of the natural prejudice caused by the pretensions of charlatans, whether its merits have been fairly tested. On the European Continent it has been successfully applied in a great variety of cases; and Bernheim has shown that minor nervous troubles, insomnia, migraines, drunkenness, lighter cases of rheumatism, s.e.xual and digestive disorders, together with a host of smaller temporary causes of pain--corns, cricks in back and side, etc.--may be cured or very materially alleviated by suggestions conveyed in the hypnotic state. In many cases such cures are permanently effected with aid from no other remedies. In a number of great city hospitals patients of recognised cla.s.ses are at once hypnotized, and suggestions of cure made. Liebeault, the founder of the Nancy school, has the credit of having first made use of hypnosis as a remedial agent. It is also becoming more and more recognised as a method of controlling refractory and violent patients in asylums and reformatory inst.i.tutions. It must be added, however, that psychological theory rather than medical practice is seriously concerning itself with this subject.

_Theory._--Two rival theories are held as to the general character of Hypnosis. The Paris school already referred to, led by the late Dr.

Charcot, hold that it is a pathological condition which is most readily induced in patients already mentally diseased or having neuropathic tendencies. They claim that the three stages described above are a discovery of great importance. The so-called Nancy school, on the other hand, led by Bernheim, deny the pathological character of Hypnosis altogether, claiming that the hypnotic condition is nothing more than a special form of ordinary sleep brought on artificially by suggestion. Hypnotic suggestion, say they, is only an exaggeration of an influence to which all persons are normally subject. All the variations, stages, curious phenomena, etc., of the Paris school, they claim, can be explained by this "suggestion" hypothesis. The Nancy school must be considered completely victorious apart from some facts which no theory has yet explained.

Hypnotism shows an intimacy of interaction between mind and body to which current psychology is only beginning to do justice; and it is this aspect of the whole matter which should be emphasized in this connection. The hypnotic condition of consciousness may be taken to represent the working of Suggestion most remarkably.

CHAPTER VIII.

THE TRAINING OF THE MIND--EDUCATIONAL PSYCHOLOGY.

A great deal has been said and written about the physical and mental differences shown by the young; and one of the most oft-repeated of all the charges which we hear brought against the current methods of teaching is that all children are treated alike. The point is carried so far that a teacher is judged from the way he has or has not of getting at the children under him as individuals. All this is a move in the right direction; and yet the subject is still so vague that many of the very critics who declaim against the similar treatment which diverse pupils get at school have no clear idea of what is needed; they merely make demands that the treatment shall suit the child. How each child is to be suited, and the inquiry still back of that, what peculiarity it is in this child or that which is to be "suited"--these things are left to settle themselves.
