There are two qualities of nervous tissues (possibly of all living tissue) that are basic in all nervous and mental processes. They are dependent upon the modificability of nerve cells and fibers by stimuli, e. g., a light flashing through the pupil and passing along the optical tracts to the occipital cortex produces changes which constitute the basis of visual memory. Experience modifies nervous tissue in definite manner, and SOMETHING remembers. Who remembers? Who is conscious? Believe what you please about that, call it ego, soul, call it consciousness dipped out of a cosmic consciousness; and I have no quarrel with you.
Memory has its mechanics, in the association of ideas, which preoccupied the early English psychologists and philosophers; it is the basis of thought and also of action, and it is a prime mystery. We know its pathology, we think that memories for speech have loci in the brain, the so-called motor memories in Broca's area.[1] We know that a hemorrhage in these areas or in the fibers passing from them, or a tumor pressing on them may destroy or temporarily abolish these memories, so that a man may KNOW what he wishes to say, understand speech and be unable to say it, though he may write it (motor aphasia). In sensory aphasia the defect is a loss of the capacity to understand spoken speech, though the patient may be able to say what he himself wishes. (It is fair to say that the definite location of these capacities in definite areas has been challenged by Marie, Moutier and others, but this denial does not deny the organic brain location of speech memories; it merely affirms that they are scattered rather than concentrated in one area.)

In its widest phases memory alters with the state of the brain. In childhood impressibility is high, but until the age or four or five the duration of impression is low, and likewise the power of voluntary recall. In youth (eighteen-twenty) all these capacities are perhaps at their highest. As time goes on impressibility seems first of all to be lost, so that it becomes harder and harder to learn new things, to remember new faces, new names.
The typical difficulty of middle age is to remember names, because these have no real relationship or logical value and must be arbitrarily remembered. The typical senile defect is the dropping out of the recent memories, though the past may be preserved in its entirety. With any disease of the brain, temporary or permanent, amnesia or memory loss may and usually is present (e. g., general paresis, tumor, cerebral arteriosclerosis, etc.). As the result of Carbon monoxide poisoning, as after accidental or attempted suicidal gas inhalation, the memory, especially for the most recent events, is impaired and the patient cannot remember the events as they occur; he passes from moment to moment unconnected to the recent past, though his remote past is clear. Since memory is the basis of certainty, of the feeling of reality, these unfortunates are afflicted with an uncertainty, a sense of unreality, that is almost agonizing. As the effects of the poison wear off, which even in favorable cases takes months, the impressibility returns but never reaches normality again.
Unquestionably there is an inherent congenital difference in memory capacity. There are people who are prodigies of memory as there are those who are prodigies of physical strength,--and without training. The IMPRESSIBILITY for memories can in no way be increased except through the stimulation of interest and a certain heightening of attention through emotion. For the man or woman concerned with memory the first point of importance is to find some value in the fact or thing to be learned. Before a subject is broached to students the teacher should make clear its practical and theoretic value to the students. Too often that is the last thing done and it is only when the course is finished that its practical meaning is stressed or even indicated. In fact, throughout, teaching the value of the subject should constantly be emphasized, if possible, by illustrations from life. There are only a few who love knowledge for its own sake, but there are many who become eager for learning when it is made practical.
The number of associations given to a fact determines to a large extent its permanence in memory and the power of recalling it. In my own teaching I always instruct my students in the technique of memorizing, as follows:
1. Listen attentively, making only as many notes as necessary to recall the leading facts. The auditory memories are thus given the first place.
2. Go home and read up the subject in your textbooks, again making notes. Thus is added the visual associations.
3. Write out in brief form the substance of the lecture, deriving your knowledge from both the lecture and the book. You thus add another set of associations to your memories of the subject.
4. Teach the subject to or discuss it with a fellow student. By this you vitalize the memories you have, you link them firmly together, you lend to them the ardor of usefulness and of victory. You are forced to realize where the gaps, the lacunae of your knowledge come, and are made to fill them in.
Thus the best way to remember a fact is to find a use for it and to link it to your interests and your purposes. Unrelated it has no value; related it becomes in fact a part of you. After that the mechanics of memory necessitate the making of as many pathways to that fact as possible, and this means deliberately to associate the fact by sound, by speech and by action. The advertised schemes of memory training are simply association schemes, old as the hills, and having value indeed, but too much is claimed for them. A splendid memory is born, not made; but any memory, except where disease has entered, can be improved by training.
It is because lectures on the whole do not supply enough associations or arouse enough interest that the lecture is the poorest method of teaching or learning. Man's mind sticks easily to things, but with difficulty to words about things. To maintain attention for an hour or so, while sitting, is a task, and there develops a tendency either to a hypnoidal state in which the mind follows uncritically, or to a restless uneasiness with wandering mind and fatigue of body. A demonstration, on the other hand, a laboratory experiment with short, personal instruction, a bodily contact with the problem calls into play interest, enthusiasm, curiosity, motor images, the use of the hands, and is THE method of teaching.
There are at present excellent psychological methods of testing out the memory capacity. Every one engaged in any responsible work, or troubled about his memory, should be so tested. While there are other qualities of mind of great importance, memory is basic, and no one can really understand himself who is in doubt about his memory. In such diseases as neurasthenia one of the commonest complaints is the "loss of memory," which greatly troubles the patient. As a matter of fact, what is impaired is interest and attention, and when the patient realizes this he is usually quite relieved. The man who has a poor memory may become very successful if he develops systems of recording, filing, indexing, but his possibilities of knowledge are greatly reduced by his defect.[1]
[1] It is the growth of the subject matter of knowledge that makes necessary the elaborate systems of indexing, etc., now so important. It is as much as man can do to follow the places where the men work, let alone what they are doing. This growth of knowledge is getting to be an extra-human phenomenon. Of this Graham Wallas has written entertainingly.
A second fundamental ability of living tissue, and of particular importance in character, is habit formation. Habit resides in the fact that once living tissue has been traversed by a stimulus and has responded by an act, three things result:
1. The pathway for that stimulus becomes more permeable; becomes, as it were, grooved or like a track laid across the living structure of the nervous system.
2. The responding element is more easily stirred into activity, responds with more vigor and with less effort.
3. Consciousness, at first invoked, recedes more and more, until the habit-action of whatever type tends to become automatic. There is in this last peculiarity a tendency for the habit to establish itself as independent of the personality, and if an injurious or undesired habit, to set up the worst of the conflicts of life,--a conflict between one's intention and an automaton in the shape of a powerfully entrenched habit.
Habits are economical of thought and energy, generally speaking; that is their main recommendation. A dozen examples present themselves at once as illustrative: piano playing, with its intense concentration on each note, with consciousness attending to the action of each muscle, and then practice, habit formation, and the ease and power of execution with the mind free to wander off in the moods suggested by the music, or to busy itself with improvisations, flourishes and the artistic touches. Before true artistry can come, technique must be relegated to habit. So with typewriting, driving an automobile, etc.
More fundamental than these, which are largely skill habits, are the organic habits. One of the triumphs of pediatrics depends upon the realization that the baby's welfare hangs on regular habits of feeding, that he is not to be fed except at stated intervals; as a result processes of digestion are set going in a regular, harmonious manner. In other words, these processes may be said to "get to know" what is expected of them and act accordingly. The mother's time is economized and the strain of nursing is lessened. In adults, regular hours of eating make it possible for the juices of digestion to be secreted as the food is ingested; in other words, an habitual adjustment takes place.
If there were one single health habit that I would have inculcated above all others, it would be the habit of regularly evacuating the bowels. While constipation is not the worst ill in the world, it causes much trouble, annoyance and a considerable degree of ill health, and, in my opinion, a considerable degree of unhappiness. A physician may be pardoned for frank advice: all the matters concerning the bowels, such as coarse foods, plenty of water and exercise, are secondary compared to the habit of going to the stool at the same time each day, whether there be desire or not. A child should be trained in this matter as definitely as he is trained to brush his teeth. In fact, I think that the former habit is more important than the latter. The mood of man is remarkably related to the condition of his gastro-intestinal tract and the involuntary muscle of that tract is indirectly under the control of the will through habit formation.
Sleep[1] the mysterious, the death in life which we all seek each night, is likewise regulated by habit. Arising from the need of relief from consciousness and bodily exertion, the mechanism of sleep is still not well understood. Is there a toxic influence at work? is the body poisoned by itself, as it were, as has been postulated; is there a toxin of fatigue, or is there a "vaso-motor" reaction, a shift of the blood supply causing a cerebral anaemia and thus creating the "sleepy" feeling? The capacity to sleep is a factor of great importance and we shall deal with it later under a separate heading as part of the mechanism of success and failure. At present we shall simply point out that each person builds up a set of habits regarding sleep,--as to hour, kind of place, warmth, companionship, ventilation and even the side of the body he shall lie on, and that a change in these preliminary matters is often attended by insomnia. Moreover, a change from the habitual in the general conduct of life--a new city or town, a strange bed, a disturbance in the moods and emotions--may upset the sleep capacity. Those in whom excitement persists, or whose emotions are persistent, become easily burdened with the dreaded insomnia. Sleep is dependent on an exclusion of excitement and exciting influences. If, however, exciting influences become habitual they lose their power over the organism and then the individual can sleep on a battle field, in a boiler factory, or almost anywhere. Conversely, many a New Yorker is lulled to sleep by the roar of the great city who, finds that the quiet of the country keeps him awake.
[1] As good a book as any on the subject of sleep is Boris Sidis's little monograph.
Sleeplessness often enough is a habit. Something happens to a man that deeply stirs him, as an insult, or a falling out with a friend, or the loss of money,--something which disturbs what we call his poise or peace of mind. He becomes sleepless because, when he goes to bed and the shock-absorbing objects of daily interest are removed, his thoughts revert back to his difficulty; he becomes again humiliated or grieved or thrown into an emotional turmoil that prevents sleep. After the first night of insomnia a new factor enters,--the fear of sleeplessness and the conviction that one will not sleep. After a time the insult has lost its sting, or the difficulty has been adjusted, there is no more emotional distress, but there is the established sleeplessness, based on habitual emotional reaction to sleep. I know one lady whose fear reached the stage where she could not even bear the thought of night and darkness. It is in these cases that a powerful drug used two or three nights in succession breaks up the sleepless habit and reestablishes the power to sleep.
People differ in their capacity to form habits and in their love of habits. The normal habits, thoroughness, neatness and method come easily to some and are never really acquired by others. People of an impetuous, explosive or reckless character, keenly alive to every shade of difference in things, find it hard to be methodical, to carry on routine. The impatient person has similar difficulties. Whereas others take readily to the same methods of doing things day by day; and these are usually non-explosive, well inhibited, patient persons, to whom the way a thing is done is as important as the goal itself.
Here comes a very entertaining problem, the question of the value of habits. Good habits save time and energy, tend to eliminate useless labor and make for peace and quiet. But there is a large body of persons who come to value habits for themselves and, indeed, this is true to a certain extent of all of us. Once an accustomed way of doing things is established it becomes not only a path of least resistance, but a sort of fixed point of view, and, if one may mix metaphors a trifle, a sort of trunk for the ego to twine itself around. There is uneasiness in the thought of breaking up habits, an uneasiness that grows the more as we become older and is deepened into agony if the habit is tinged with our status in life, if it has become a sort of measure of our respectability. Thus a good housekeeper falls into the habits of doing things which were originally a mark of her ability, which she holds as sacred and values above her health and energy. There are people who fiercely resent a new way of doing things; they have woven their most minor habits into their ego feeling and thus make a personal issue of innovations. These are the upholders of the established; they hate change as such; they are efficient but not progressive. In its pathological form this type becomes the "health fiends" who never vary in their diet or in their clothing, who arise at a certain time, take their "plunge" regardless, take their exercise and their breakfasts alike as a health measure without real enjoyment, etc., who grow weary if they stay up half an hour or so beyond their ordinary bedtime; they are the individuals who fall into health cults, become vegetarians, raw food exponents, etc.
Opposed to the group that falls into habits very readily is the group that finds it difficult to acquire habitual ways of working and living. All of us seek change and variety, as well as stability. Some cannot easily form habits because they are quickly bored by the habitual. These restless folk are the failures or the great successes, according to their intelligence and good fortune. There is a low-grade intelligence type, without purpose and energy, and there is a high-grade intelligence type, seeking the ideal, restless under imperfection and restraint, disdaining the commonplace and the habits that go with it. Is their disdain of habit-forming and customs the result of their unconventional ways, or do their unconventional ways result because they cannot easily form habits? It is very probable that the true wanderer and Bohemian finds it difficult, at least in youth, to form habits, and that the pseudo-Bohemian is merely an imitation.
Habit is so intimately a part of all traits and abilities that we would be anticipating several chapters of this book did we go into all the habit types. Social conditions, desire, fatigue, monotony, purpose, intelligence, inhibition, all enter into habit and habit formation. Youth experiments with habit; old age clings to it. Efficiency is the result of good habits but originality is the reward of some who discard habits. A nation forms habits which seem to be part of its nature, until emigration to another land shows the falsity of this belief. So with individuals: a man feels he must eat or drink so much, gratify his sex appetite so often, sleep so many hours, exercise this or that amount, seek his entertainment in this or that fashion,--until something happens to make the habit impossible and he finds that what he thought a deeply rooted mode of living was a superficial routine. Though good habits may lead to success they may also bar the way to the pleasures of experience; that is their danger. A man who finds that he must do this or that in such a way had better beware; he is getting old, no matter what his age.[1] For we grow older as we lose mobility,--in joints, muscles, skin and our ways of doing, feeling and thinking! It is a transitory stage of the final immobility of Death.
[1] Says the talkative Autocrat of the Breakfast Table: "There is one mark of age that strikes me more than any of the physical ones; I mean the formation of Habits. An old man who shrinks into himself falls into ways that become as positive and as much beyond the reach of outside influences as if they were governed by clock work."
We have not considered the pathological habits, such as alcoholism, excessive smoking and eating, perverse sex habits. The latter, the perverse sex habits, will be studied when discussing the sex feelings and purposes in their entirety. Alcoholism is not yet a dead issue in this country though those who are sincere in wishing their fellows well hope it soon will be. It stands, however, as a sort of paradigm of bad habit- forming and presents a problem in treatment that is typical of such habits.
Not all persons have a liability to the alcoholic habit. For most people lack of real desire or pleasure prevented alcoholism. The majority of those who drank little or not at all were not in the least tempted by the drug. "Will power" rarely had anything to do with their abstinence and the complacency with which they held themselves up as an example to the drunken had all the flavor of Phariseeism. To some the taste is not pleasing, to others the immediate effects are so terrifying as automatically to shut off excess. Many people become dizzy or nauseated almost at once and even lose the power of locomotion or speech.
In many countries and during many centuries most of those who became alcoholic were such largely through the social setting given to alcohol. Because of the psychological effects of this drug in removing restraint, inhibition and formality, in its various forms it became the symbol of good-fellowship; and because it has an apparent stimulation and heat-producing effect there grew up the notion that it aided hard labor and helped resist hardship. As the symbol of good-fellowship it grew into a tradition of the most binding kind, so that no good time, no coming together was complete without it, and its power is celebrated in picturesque songs and picturesque sayings the world over. Hospitality, tolerance, good humor, kindliness and the pleasant breaking down of the barriers between man and man, and also between man and woman, all these lured generation after generation into the alcoholic habit.
There are relatively normal types of the heavy drinker,--the socially minded and the hard manual worker. But there is a large group of those who find in alcohol a relief from the burden of their moods, who find in its real effect, the release from inhibitions, a reason for drinking beyond the reach of reason. Do you feel that the endless monotony of your existence can no longer be borne,--drink deep and you color your life to suit yourself. Do disappointment and despair gnaw at your love of life so that nothing seems worth while,--some bottled "essence of sunshine" will give new, fresh value to existence. Are you a victim of strange, uncaused fluctuations of mood so that periodically you descend to a bottomless pit of melancholy, --well, then, why suffer, when over the bar a man will furnish you a release from agony? And so men of certain types of temperament, or with unhappy experiences, form the alcoholic habit because it gives them surcease from pain; it deals out to them, temporarily, a new world with happier mood, lessened tension and greater success.
Seeking relief[1] from distressing thoughts or moods is perhaps one of the main causes of the narcotic habit. The feeling of inferiority, one of the most painful of mental conditions, is responsible for the use not only of alcohol but also of other drugs, such as cocaine, heroin, morphine, etc. One of the most typical cases of this I have known is of a young man of twenty-five, a tall fellow with a very unattractive face who had this feeling of inferiority almost to the point of agony, especially in the presence of young women, but also in any situation where he would be noticed. He was fast becoming a hermit when he discovered that a few drinks completely removed this feeling. From that time on he became a steady drinker, with now and then a short period when he would try to stop drinking, only to resume when he found himself obsessed again by the dreaded inferiority complex.
[1] This is the main theme of De Quincey's "Confessions of an Opium Eater."
Similarly a shameful position, such as that of the prostitute or the chronic criminal, is "relieved" by alcohol and drugs, so that the majority of these types of unfortunates are either drunkards or "dopes." Too often have reformers reversed the relationship, believing that alcohol caused prostitution and crime. Of course that relationship exists, but more often, in my experience, the alcohol is used to keep up the "ego" feeling, without which few can bear life.
Curiously enough, one of the sex perversions, masturbation, has in a few cases a similar genesis. I have known patients who, when under the influence of depression, or humiliated in some way or other, found a compensating pleasure in the act. Here we come to a cardinal truth in the understanding of ourselves and our fellows and one we shall pursue in detail later,--that face to face with mental pain, men seek relief or pleasure or both by alcohol, drugs, sensual pleasures of all kinds, and that the secret explanation of all such habits is that they offer compensation for some pain and are turned to at such times. What one man seeks in work, another man seeks in religion, another finds in self-flagellation, and still others seek in alcohol, morphine, sexual excesses, etc.
With the increasing excitement and tension of our times there is a constant search for relief, and here is the origin of much of the smoking. Most men find in the deliberate puff, in the slow inhalation and in the prolonged exhalation with the formation of the white cloud of smoke, a shifting of consciousness from the major businesses of their mind, from a constant tension to a minor business not requiring concentration and thereby breaking up in a pleasurable, rhythmic fashion the sense of effort. When one is alone the fatigue and even the pain of one's thinking is relieved by shifting the attention to the smoking. Keeping one's attention at a high and constant pitch is apt to produce a restless fatigue and this is often offset to the smoker by his habit. Excessive smoking may cause "nervousness" but as a matter of fact it is more often a means by which the excessively nervous try to relieve themselves. Of course it is not good therapeutics under such conditions, but I believe that in moderation smoking does no harm and is an innocent pleasure.
Some of the pathological motor habits, such as the tics, often have a curious background. The most common tics are snuffing, blinking, shaking of the head, facial contortions of one kind or another. These arise usually under exciting conditions or in the excitable, sometimes in the acutely self-conscious. Frequently they represent a motor outlet for this excitement; they are the motor analogues of crying, shouting, laughing, etc. (Indeed, a common habit is the one so frequently heard,--a little laugh when there is no feeling of merriment and no occasion for it.) Motor activity discharges tension and is pleasurable and these tics furnish a momentary pleasure; they relieve a feeling that some of the victims compare to an itch and the habit thus is based on a seeking of relief, even though that relief is obtained in a way that distresses the more settled purposes of the individual.
In the establishment of good habits, those desirable from the point of view of the important issues of life, training is of course essential. But in the training of children, certain things must be kept in mind: the usefulness, the practical value must be presented to the child's mind in a way he can understand, or else various ways of energizing him to help in the formation of the habit must be used--praise and blame, reward and punishment. Further, these habits are not to be held holy; cleanliness and method are desirable acquisitions but not so desirable as a feeling of freedom to play and experiment with life and things. If the child is constantly worried lest he get too dirty, or fears to play in his room because he may disorder it, he is forming the good habits of cleanliness and method but also the worse one of worry.
In the breaking of a bad habit, its root in desire and difficulty must be discovered. Often enough a man does not face the source of his trouble, preferring not to. I am not at all sure that it is best in all cases for a man to know his own weakness; in fact, I feel convinced to the contrary in some cases. But in the majority of difficulties, self-revelation is salutary and makes an intelligent coping with the situation possible. Here is the value of the good friend, the respected pastor, the wise doctor. The human being will always need a confessor and a confidante, and he who is struggling with a habit is in utmost need of such help.
Shall the struggler with a bad habit break it with its thralldom? Shall he say to his chains, "From this time, nevermore!" To some men it is given to win the victory this way, to rise to the heights of a stubborn resolution and to be free. But not to many is this possible. To others there is a long history of repeated effort and repeated failures and then--one day there comes a feeling of power, perhaps through a great love, a great cause, a sermon heard, a chance sentence, or a bitter experience, and then, like a religious conversion, the tracks of the old habit are obliterated, never to be used again.
I have in mind two men, both heavy drinkers but differing in everything else. One was a philosopher who saw the world in that dreadful, clear white light of which Jack London[1] spoke, that light which leaves no cozy, pleasant obscurities, in which Truth, the naked, is horrible to look at, when life seems too unreal, when purposes seem most futile. At such times he would get drunk and be happy for the time being, and afterwards find himself bitterly repentant, though even that was a pleasure compared to the hollow world in which his sober self dwelt. Then one day, when all his friends had given him up as hopeless, as destined for disaster, he read a book. "The Varieties of Religious Experience," by William James, came to him as a clear light comes to a man lost in the darkness; he saw himself as a "sick soul," obsessed with the idea that he saw life relentlessly and clearly. There came to him the conviction that he had been arrogant, a conceited ass, bent on ruin, "a sickly soul," he said. Out of that realization grew resolutions that needed no vowing or pledging, for as simply as a man turns from one road to another he turned from his habit into healthy-minded work.
[1] Jack London's "John Barleycorn."
The other was an essentially healthy-minded man but he loved joviality, freedom and good fellowship. Without ever knowing how he came to it, he found himself a confirmed drinker, holding an inferior place, passed by men of lesser caliber. He struggled fitfully but always slipped when the next "good fellow" slapped him on the back and invited him to have a drink. One day he stepped out of a barroom with a group of his cronies, and though he walked straight there was a reckless, happy feeling in him that pushed him on to his folly. A young lady standing on a street corner waiting for a car caught his eye. Signaling to his companions, he walked up to her, put his arms around her and kissed her. The girl stood as if petrified, then she pushed him off and looked him up and down deliberately with cold scorn in her eyes. Then she took off her glove and slapped him across the face with it, as if disdaining to use her hand. With that she walked away.
The man was a gentleman, and he stood there stricken. The laugh of his companions aroused him. He saw them as if they were himself, with a horror and disgust that made him suddenly run away from them.
"From that moment I never again had the slightest desire for drink. The slap sobered me for good."
While these conversions occur now and then there are certain practical points in the breaking of a habit that need attention in each case.
In the first place it is best in the majority of instances to avoid the particular stimuli and associations that set off the habit. The stimulus is a kind of trigger; pull it and the habit can hardly be checked. Whatever the situation is that acts as the temptation, avoid it. Not for nothing do men pray, "Lead us not into temptation." The will needs no such exercise and rarely stands up well against such strain. This may mean a removal for the time being from the source of temptation, a flying away to gain strength.
Further, a substitution of habit, of purpose, is necessary. Some line of activities must be selected to fill in the vacuum. A hobby is needed, a devotion to some larger purpose, whether it be in work or social activity. "Nature abhors a vacuum"; boredom must be avoided, for that is a pain, awakening desire. The gymnasium, golf, sports of all kinds are substitute pleasures of great value.
Third, harness a friend, a superior or a respected equal to the yoke with you. Pull double harness; let him lend his strength to yours. Throw away pride; confess and receive new energy from his sympathy and wisdom. If you are lucky enough to have such a friend, or some wise counselor, thank God for him. For here is where the true friend finds his highest value.
In the analysis of any character the question of the kind of habits formed demands attention. Since almost all traits become matters of habit, such an inquiry would sooner or later lead to a catalogue of qualities. What is here pertinent is this,--that one might inquire into the kind of habits that are easily formed by the individual and the kind that are not. Habits fall into groups such as these:
1. Relating to care of the body: cleanliness, diet, exercise, bowel function, sleep. Here we learn about personal tidiness or the reverse, foppery, dandyism, gluttony, asceticism, etc.
2. Relating to method, efficiency, neatness in work: some people find it almost impossible to become methodical or neat; others become obsessed by these qualities to the exclusion of mobility.
3. Relating to the pursuit of pleasure: type of pleasure sought, time given to it, hobbies.
4. Relating to special habits: alcohol, tobacco, drugs, sex perversions.
5. Relating to study and advancement: love of books, attendance at lectures.
Especially in the study of children is some such scheme essential, for then one gets a definite idea of their defects and takes definite efforts to make habitual the desired practice, or else one sees the special trend, and, if it is good, fosters it. This, of course, is the long and short of character development.
