Upon these considerations, the importance of unconscious cerebration is brought home to the physician. It is impossible for a great many people to keep their minds inactive, and this is particularly true of two cla.s.ses of people: those who have superabundant mental energy and those who lack self-control. To both of these cla.s.ses of men and women, the physician must point out the dangers of unconscious cerebration--the occupation of mind with some subject, even at times while they imagine they are occupied with something else, or even during sleep. Such continuous occupation with a single subject is dangerous. Physicians must emphasize that many supposed {140} mental occupations are really so superficial that they allow other more exhausting processes to continue below them in the sphere of consciousness. As a consequence, the mind, instead of being relaxed, is really more tense than before, because occupied with two sets of thoughts. Very often it would be better for such people to continue with the more serious problem until its solution came, or until they realized that they must divert themselves.

MENTAL RELAXATION

What is important for mental relaxation, apparently, is not that a man shall try to set his mind at absolute rest, for that seems to be impossible, if a man really has a mind; nor that he shall occupy it with trivial things (because his interest will not be caught by them and will revert to the last serious thing that he was doing), but that he shall have an outlet for mental activity in entirely another direction from that to which he usually devotes himself. In other words, it is important that a man shall have a hobby, and that he shall ride that hobby whenever his ordinary business, whatever that may be, will permit him, and the more interesting the hobby, the better.

REMEDIAL MEASURES

The most important general remedy for over-prolonged mental occupation with a single subject, is some outdoor sport or form of exercise that requires all the attention. Horseback exercise is particularly valuable; boating, especially where the man has charge of the boat himself and where he has to have his wits about him, and the various sports. It is particularly important that men should not be alone during the taking of their exercise and diversion of mind. Above all, human interests take a man outside of himself and keep him from disturbing his mental equipoise by too much devotion to a single subject.

CHAPTER VII

DISTANT MENTAL INFLUENCE

There is a very general impression that it is possible, at least under certain circ.u.mstances, for one human mind to influence another at a distance without any of the ordinary known means of communication.

Many people have had the experience of thinking about a friend whom they have not seen for a long while, and shortly after meeting him.

Sometimes it is found that the friend was making up his mind to bring about the meeting just about the time that the thought of him came.

Many have had the experience of writing a letter and having it cross in the mails with another from their correspondent, evidently written within a few hours, though there had perhaps been no communication for weeks or months before. There are people who insist that they can, by concentrating the mind and fixing their eyes on the head of a {141} person some distance in front of them in a theater, or a railway car, cause the person to turn around. There are others who say that by thinking strongly of some person in a distant part of a large room, that person can be made to think of them. In general, there are many persons who are quite sure that there is evidence enough to indicate the possibility of distant mental influence, or, as it has come to be called learnedly, telepathy.

Telepathy, from the two Greek words, _tele_, at a distance, and _pathos_, feeling, has been much discussed in recent years. Many people who use the word glibly are inclined to think they know much about it. A long word, however, is not an explanation, and, just here, George Eliot's expression "we map out our ignorance in long Greek names" is worth recalling. There are a number of phenomena that seem to require some such theory as that of telepathy, but the phenomena are still under discussion and their significance is by no means clear. As we understand it, telepathy may mean either thought transference or mind reading, that is, either the active process by which we communicate our thought to someone at a distance, or the pa.s.sive process by which we receive communications from others. These thoughts include the idea of mental influence at a distance; that is, we can by willing influence the wills, or at least the motives to action, of people at a distance and they may, in turn, influence ours.

The further thought has come, that since the mind largely influences the body in matters of health, so mental influence from a distance by affecting mind, may either improve or injure health.

Some sensitive people are disturbed by the thought that they may be influenced from a distance by others, or at least that suggestions that come to them, may be due to telepathic influence. Investigation would probably show that there are at least as many persons disturbed by real or supposed telepathic influences as there are of those who have hallucinations. Sometimes it is said that such persons are not quite sane, but the more experience a physician has with them, the more he dismisses the thought of insanity and proceeds to use contrary suggestion and frank discussion, in order to counteract the mental influences. Insane persons think they are being influenced from a distance just as they hear voices and see visions, but such hallucinations may occur to the sane, as apparent telepathic experiences may also.

Witchcraft.--It used to be a common belief that people could be influenced, even at a distance, by the mere evil wishes or intentions of others. After all, the old beliefs in witchcraft that were so common in Europe and in America until well into the eighteenth century represent the conviction of mankind that at least certain people might, from a distance, seriously influence them for evil. Always the fear of malign influence was uppermost in people's minds and literally hundreds of thousands of witches were prosecuted, and many thousands of them put to death, because of this belief in the possibility of their working evil to others at a distance, merely by willing it.

Occasionally some such material auxiliary to malign purpose as an image in wax of the one to whom the evil was to be done was used. Into this the ill wisher stuck pins according to the part that he or she would want to be affected in the enemy, but as a rule the will, and nothing more, was used.

Absent Treatment.--In our own time a system of healing, that has attracted many followers, has taken up the idea of beneficent mental influence at a distance. "Absent treatment" has now become a familiar expression. {142} That those who believe in such favorable influence at a distance should also believe in unfavorable influence seems inevitable. As a matter of fact, we know that the founder of this special sect always insisted on the power for evil over herself and her followers of those who want to exert the injurious influence of animal magnetism--malicious animal magnetism as it is called. A very definite attempt was made to bring a case of this kind before the courts, the subject matter of which exactly resembled some of the old witchcraft trials in New England! And in spite of the insistence and emphatic a.s.sertion that no such thing is intended, from the principles that are accepted the necessary logical conclusion is a return to the belief in witchcraft.

Malignant Magnetism.--As a number of persons are likely to fear such evil influence of others upon them, the question of the possibility of it must come up for discussion in order that its status may be clear in the physician's mind, for by just as much as he can make certain to the patient that modern psychology refuses to accept distant influence, will he be able to rea.s.sure his patient. Of course, the patients who come with such complaints have usually some element of mental trouble. The alienist sees any number of people who are sure that enemies at a distance are working spells upon them, some by electrical, some by magnetic means, and some by telepathic absent treatment, or absent ill-wishing. Such notions are the delusions of the disequilibrated and these persons often cannot be reasoned with.

Yet very often a distinct delusion may be reasoned out of even a subrational person, if it is taken seriously, and some striking expression of its irrationality and of its total disagreement with scientific views can be shown to the patient.

Action Without a Medium.--The medieval scholastic philosophers quoted as an absolutely accepted principle the Latin axiom, _"actio in distans repugnat."_ Literally translated this means action at a distance is repugnant to reason. Expressed less technically, the principle declares that any action of one body on another, where there is no medium connecting them, no link that in some way places them in contact with one another, is absurd. The expression _in distans_ means that the two bodies are separated from one another and stand in two places having no connection of any kind. This principle would ordinarily seem to preclude the possibility of one person acting on another, unless there is some mode of communication.

Crookes' Theory.--Sir William Crookes, at a meeting of the British a.s.sociation for the Advancement of Science about ten years ago, in discussing telepathy, directed attention to the fact that there exists by scientific hypothesis, generally accepted, a definite medium of communication by which minds at a distance might influence one another. The medium is the ether which, according to physical theories, besides carrying light, also carries heat and electrical waves, and in recent years is recognized as transmitting the impulses of wireless telegraphy. It is possible that when the cells of certain human minds are stimulated to a particular phase of vibration, they may, even at long distances, affect the cells of other individuals that resemble them, or are attuned to them, that is, have the same moment of vibration. This is the principle which underlies wireless telegraphy. Whether the vibrations of living nerve cells can be made thus to radiate out over the ether and arouse in any way other cells, especially to the extent of communicating ideas, is a matter still open for investigation. The possibility of this occurring {143} cannot be denied. We are, however, still in the presence of a condition and not a theory. The question is whether minds are thus influenced at a distance--whether we have data enough to establish the occurrence of telepathy or mental communications of any kind at a distance.

No Practical Thought Transfer.--At the beginning, it is of the greatest importance to recall that, while many people think there must be something in telepathy and presume that the investigations of recent years have shown not only the possibility of the communication of ideas from mind to mind and of the mental influence of one person over another, even at long distances, but also its actual occurrence, yet all our ordinary life is founded on the absolute negation of any such phenomenon. For instance, our courts of law are conducted in direct contradiction of the possibility of anything like telepathy.

Juries are summoned of twelve good men and true who, as far as possible, know nothing about the prisoner and as little as may be about the case. They are supposed to get all their information in the court room. We do not believe that any of them by any wonderful process might be able to know what was going on in the prisoner's mind in spite of his plea. Nor do we think for a moment that they can know what is going on, apart from what he communicates in evidence, in the mind of any witness. Neither is there the slightest presumption that the judge or any of our lawyers can know anything about what is in the minds of any of the persons present, except as they reveal it by outward signs.

A lawyer who could employ telepathy with success would be simply invaluable. Before a month had pa.s.sed, he would have all the business of the criminal courts in his hands.

Mental Retention.--In answer to this it may be said that these represent conditions in which determined effort is made to keep all possible information that may be in the minds of all concerned from pa.s.sing to others. Everyone concedes the power of such absolute self retention of our thoughts, when we deliberately wish to keep them from being known to others. When people wish to communicate their thoughts to others, then it may be different. In that case the sending and receiving minds are both active and the conditions for interaction, if it were at all possible, would be favorable. Just this condition obtains in the court room every day. An innocent prisoner wants with all his heart and soul to communicate the idea of his innocence to the judge and jury. Of course, he does not succeed by telepathic means in transferring to them any inkling of the truth. On the contrary, his very nervousness and anxiety to set himself right before them will sometimes actually cause prejudice.

The rule that has thus been exemplified in our courts of law holds for all business transactions. The ordinary customs of business presume that the buyer does not know what the seller paid for the particular article that is being exchanged, and it is on the strength of this that profit becomes possible. A few telepathic merchants or customers would work serious havoc in business life.

What thus holds for important affairs in life is just as strikingly exemplified in the trivial round of social existence and in our intercourse with friends. Suppose one woman knew what another woman thought of her!

That charming, old-fashioned inst.i.tution "courting" would go entirely by {144} the board, if there were any such thing as real telepathy. In general, social life in all its features would become very, very different to what it is.

How Much Slight External Expression Conveys.--Mrs. Coventry Patmore, the English poet's wife, once told a little story of some people who lived in a distant island where the inhabitants possessed tails. These tails were, as they are on the animals, organs of expression, but of involuntary and quite unconscious expression. It was utterly impossible for the people there to say nice things to one another when they had quite other things in mind, because if they did not like the person their tails hung down behind; if they did like them they wagged rather vigorously, no matter what their owner might be saying. This simple revelation of feelings, so much less than even the slightest degree of telepathy would occasion, was quite enough to work a revolution in the social affairs of this romantic island. It made the people truthful and candid in their relations with one another.

Negation of Telepathy.--There is, perhaps, some evidence of the occurring of telepathy in special cases, but all of our present-day life is organized on a firm basis of complete negation of the existence or occurrence of telepathy to even the slightest degree.

Every-day experiences teach us that husbands and wives, even those who have the greatest love and confidence toward each other, do not really know their life partners, for it frequently happens that something turns up which reveals an unsuspected side of character even after many years of intimate union.

We human beings are "infinitely repellent particles," to use the phrase, of Matthew Arnold. We never get close enough to one another to have a real glimpse into the depths of other minds. The information that is supposed to pa.s.s by telepathy from one person to another is so often just the kind that we would most sedulously conceal. There is extreme unlikelihood then that any such pa.s.sage of information takes place. The cases cited, as proof of this transference of thought, are much more likely to be coincidences than any evidence of true telepathy.

Supposed Examples of Telepathy.--In the first place, though there are opportunities for the exhibition of the phenomena of telepathy every day and every hour of existence, the cases in which it is supposed to occur are extremely rare and are distant from one another, both in time and place. Even the people who claim to have had the phenomena of telepathy happen to them once or twice, do not pretend that it is at all a common occurrence with them, and as for the supposed exhibitions of telepathy upon the stage, these have been exposed over and over again as the simplest fakes.

As to the cases of telepathy that have been reported, with careful collection of evidence, to the psychic research societies, and which are few in number, though some of them are very difficult to explain, there is no reason why they should not be striking coincidences rather than startling examples of telepathy. An example will ill.u.s.trate what I mean:

A few years ago what seemed to be a complete case of telepathy was reported in connection with a railroad accident. A Western man about to take an express train for the East was the object of a good deal of solicitude. There had previously been a series of accidents to this very fast train which he was to take. This fact had been discussed in the family, and did not tend to allay the fears of those who remained at home. During the night the {145} train actually left the track, and the car in which the subject of the story was asleep rolled down the bank.

At the moment his train went down the bank the thought of his wife and daughter came very vividly to his mind. For a moment the awful position in which they would be placed if anything serious happened to him occupied his mind to the exclusion of all other thoughts. As soon as he could, he telegraphed home that he was unhurt, with the understanding that the telegram should not be delivered before the following morning.

During the night mother and daughter sleeping in adjoining rooms were wakened at the same moment, and very seriously disturbed, by something, they knew not quite what. They rose at once to go to each other and met at the door. They felt vaguely that father was in some way connected with their awakening and disturbance of mind. After they received his telegram they were sure that what disturbed them during the night was the telepathic communication of father's danger. Each had, however, deliberately kept from speaking of her impression. When they found that he had pa.s.sed through the danger unhurt, they were sure that it was a call from him that each had heard.

This bears most of the ear-marks of a genuine case of telepathy. Here are minds whose cells by custom and inheritance are finely attuned to those of a distant mind that is suddenly very much disturbed. If the perturbations of that first mind were carried through the ether by a sort of wireless telegraphy, it would apparently not be very surprising. So carried, they woke the receptive cells of similar minds at a long distance, and mother and daughter felt the thrill at the same instant. Vague though it was, there was a telepathic message.

But there were other pa.s.sengers in this train who had near and dear relatives, yet none of them received communications. There have been literally hundreds of thousands of other accidents in the past fifty years of railroading in which pa.s.sengers who have been put in very serious danger, have thought intensely of their loved ones, and yet, there has been at most only a dozen or so examples of vague telepathy of this cla.s.s. Similar cases to this are extremely rare, though accidents in America are very frequent. At most, then, we are in the presence of a very exceptional case. Such cases would mean nothing as evidence for a scientific law, since they occur so rarely as to aptly exemplify the old adage that the exception proves the rule. The rule evidently is that there is no communication at a distance, hence the surprise when there seems to be some reason for thinking that a communication has actually taken place. Instead of proving that telepathy occurs, such cases make it clear, to the limit of demonstration, that telepathy does not occur unless some extremely special conditions intervene to make it possible.

How much more easy it is to explain such a case on the score of coincidence! Of course, mother and daughter, with father absent, and absent in the midst of what they thought was danger, would go to bed anxiously thinking of him. They would sleep lightly because of the worry. Any slight unusual noise would wake them, and at once the thought of father and his danger would occur to them. If the noise was sudden, and not repeated, and therefore inexplicable to one awakened out of sleep, they would probably be so disturbed that it is easy to understand that they would arise at once and seek each other's company. Their meeting, therefore, in the doorway between their rooms would be readily explicable. Neither would say much {146} about the subject uppermost in her thoughts in order to shield the other. The telegram in the morning would throw a glow of retrospective light on the events and seem to give an entirely new significance to their thoughts. The whole affair, though only a coincidence, would seem to be a demonstration of telepathy.

Even more marvelous instances of coincidence, in which there was no question of anything more than coincidence, have been related. The English Psychical Research Society reported the case of a young man sent to find some trace of his brother who had disappeared mysteriously from a steamer sailing from Plymouth to Lisbon. On board the steamer late at night he stood by the rail thinking of his lost brother and wondering what could possibly have become of him. Suddenly as he looked down into the ocean a body came bobbing up out of the waves almost directly under his gaze. He reported it to the officers of the vessel and it was grappled for and lifted aboard. It proved to be the body of his brother. Is this an example of telepathy, that is, of the mental influence of the perturbed spirit of the live brother upon the dead brother's body floating below the surface? No one would stretch supposed telepathy to that extent. The steamer disturbed the body which had been floating below the surface, as bodies do, gradually developing within themselves the gases of decomposition.

After a time any slight disturbance, as, for instance, the booming of a cannon or the pa.s.sage of even a small boat, will bring a body up. It so happened that the brother was on the spot, and actually thinking of the body, but that was the merest coincidence. There was no connection of cause and effect.

Most of the cases of so-called telepathy can be explained in this way.

As we have said, no source of error is so copious as that of concluding that because one thing happens after another therefore the second is caused by the first. People who are so inclined will still continue to accept such a notion of connection of cause and effect, however, and we shall have many cases of supposed telepathy exploited for us on no better grounds than this.

Twins and Telepathy.--There is a definite popular impression that twins are gifted with the power of telepathic communication much more than others. Accepting Sir Wm. Crookes' theory, the possibility of mental reciprocal influence, even at a distance, is greater for them, since their brain cells must be considered as having corresponding moments of vibration. Twins of the same s.e.x, especially those who resemble one another closely, are usually born from a single ovum. The intimate relations of two such beings to each other can be readily understood, so that we have many stories of mental communication at long distances and curious warnings, forebodings and communications of danger, and especially of sickness and death.

Especially does one find stories of wraith-like appearances of one to the other of such persons at the moment of death. A series of these stories, apparently well authenticated, is published by the Psychic Research Society. There are also a number of tales, seemingly well attested, of cloud-like shapes of other persons at the moment of death. As a consequence, there has been developed an idea that there is some evidence of the distinct possibility of such appearances when the soul leaves the body. It, however, seems very doubtful whether these are anything more than a very striking coincidence. Twins are likely to be almost constantly in one another's minds, so there is abundant {147} room for coincidences. But any number of twins have died at a distance from each other without there being any such warning. Occasionally such startling appearances occur in connection with people who are so slightly related, or whose existence bears such slight importance to each other, that it is hard to understand why the appearance may have come. Whether they are anything more than the figment of an excited imagination remains to be seen, for, while we have a little positive evidence, this only emphasizes the possibility of coincidental day-dreaming in nervous persons.

Negative Tests.--We hear much of the possibility of reading minds at a distance, or of getting definite information from sealed doc.u.ments and the like, but it must not be forgotten that whenever definite conditions have been set down, so that all the actions of the supposed clairvoyant could be controlled, then telepathy has always failed to be manifested. Sir James Simpson, for instance, publicly offered to give a five-hundred-pound note, which he had placed in a safe deposit vault, to anyone who could read its number which he had carefully impressed on his own mind. Needless to say, no one got it. In the days when Bishop, the exhibiting mind reader, was creating such a furore in New York and London by supposedly reading people's minds, Labouchere, the editor of London _Truth_, offered a similar opportunity to Bishop, but advantage of it was not taken. Bishop's power was entirely due to muscle reading. People make involuntary movements of muscles that are very slight, but sufficient for a trained observer to notice, especially if his hand is on the individual experiencing the emotions, and the consequent muscle reflexes. [Footnote 19] About the middle of the last century, the French Academy made a labored investigation of telepathy and found that whatever there seemed to be in it, when control was not properly kept, it at once was demonstrated to be impossible when conditions were planned so as to prevent deception.
