The Foundations of Personality Part 5

The simple reflex, immediate response to a stimulus, has only a limited field in human life or adult life. Sherrington points out in his notable book, "The Integrative Action of the Nervous System," that there is a play of the entire organism on each responding element, and there is also a compet.i.tion throughout each pathway to action. Let us examine this a little closer.

A man is hungry, let us say; i. e., there arise from his gastro-intestinal tract and from the tissues stimuli which arouse motor mechanisms to action and the man seeks food. The need of the body arouses desire in the form of an organic sensation and this arouses mechanisms whose function is to satisfy that desire.

Let us a.s.sume that he finds something that looks good and he is about to seize it when an odor, called disagreeable, a.s.sails his nostrils from the food, which stops him. Then there arises a compet.i.tion for action between the desire for food and the visual stimulus, a.s.sociated memories, etc., on the one hand, and the odor, the awakened fear, memories, disgust, etc., on the other hand. This struggle for action, for use of the mechanisms of action, is the struggling of choosing, one of the fundamental phenomena of life. In order for a choice to become manifest, what is known as inhibition must come into play; an impulse to action must be checked in order that an opposing action can be effective. The movement of rejection uses muscles that oppose the movement of acquirement; e. g., one uses the triceps and the other the biceps, muscles situated in opposite sides of the upper arm and having antagonistic action. In order for triceps to act, biceps must be inhibited from action, and in that inhibition is a fundamental function of the organism. In every function of the body there are opposing groups of forces; for every dilator there is a contractor, for every accelerator of action there is inhibition. Nature drives by two reins, and one is a checkrein.

This function of inhibition, then, delays, r.e.t.a.r.ds or prevents an action and is in one sense a higher function than the response to stimulation. Its main seat is the cerebrum, the "highest" nervous tissue, whereas reflex and instinctive actions usually are in the vegetative nervous system, the spinal cord, the bulbar regions and the mid-brain, all of which are lower centers. Choice, which is intimately a.s.sociated with inhibition, is par excellence a cerebral function and in general is a.s.sociated with intense consciousness. The act of choosing brings to the circ.u.mstances the whole past history of the individual; it marshals his resources of judgment, intelligence, will, purposes and desires.

In choice lies the fate of the personality, for it is basically related to habit formation. Further, in the dynamics of life a right, proper choice, an appropriate choice, opens wide the door of opportunity, whereas an unfortunate choice may commit one to the mercies of wrecking forces. Education should aim to teach proper choosing and then proper action.

The capacity for perceiving and responding to stimuli, for inhibiting or delaying action and for choosing, are of cardinal importance in our study. But there is another phase of life and character without which everything else lacks unity and is unintelligible. From the beginning of life to the end there is choice. Who and what chooses? From infancy one sees the war of purposes and desires and the gradual rise of one purpose or set of purposes into dominance,--in short, the growth of unity, the growth of personality. The common man calls this unity his soul, the philosopher speaks of the ego and implies some such thing as this organizing energy of character.

But a naturalistic view of character must reject such a metaphysical ent.i.ty, for one sees the organizing energy increase and diminish with the rest of character through health, age, environment, etc. Further, there is at work in all living things a similar something that organizes the action of the humblest bit of protoplasm. This organizing energy of character will be, for us, that something inherent in all life which tends to individualize each living thing. It is as if all life were originally of one piece and then, spreading itself throughout the world, it tended to differentiate and develop (according to the Spencerian formula) into genera, species, groups and individuals.

This organizing energy works up the experiences of the individual so that new formulae for action develop, so that what is experienced becomes the basis of future reaction.

It must be remembered that the world we live in has its great habits. Night follows day in a cycle that never fails, the seasons are repeated each year, and there is a periodicity in the lives of plants and animals that is manifested in growth, nutrition, mating and resting. Things happen again and again, though in slightly altered form, and our desires, satisfied now, soon repeat their urge. The great organic needs and sensations repeat themselves and with the periodic world of outer experience must be dealt with according to a more or less settled policy. It is the organizing energy that works out the policy, that learns, inhibits, chooses and acts,--and it is the essential character-developing principle. For like our bodily organs which are whipped into line by the nervous system, our impulses, instincts, and reflexes[1] have their own policy of action and therefore need, for the good of the entire organism, discipline and coordination. It may sound as if the body were made up of warring ent.i.ties and states and that there gradually arose a centralized good, and though the a.n.a.logy may lead to error, it offers a convenient method of thinking.

[1] Roux, the great French biologist, has shown that each tissue and each cell competes with the other tissues and the other cells. The organism, though it reaches a practical working unity as viewed by consciousness, is nevertheless no ent.i.ty; it is a collection, an aggregate of living cells which are organized on a cooperation basis just as men are, but maintain individuality and compet.i.tion nevertheless.

Moreover, the organizing energy seems often to be at work when consciousness itself is at rest, as in sleep. Often enough a man debates and debates on lines of conduct and wakes up with his problem solved. Or he works hard to learn and goes to bed discouraged, because the matter is a jumble, and wakes up in the morning with an orderly and useful arrangement of the facts. A writer seeks to find the proper opening,--and gives up in a frenzy of despair. He is perhaps walking or driving when suddenly he lifts his head as one does who is listening to a longed-for voice, and in himself he finds the phrases that he longs for.

Something within has set itself, so it seems, the task of bringing the right a.s.sociations into consciousness. What we call quickness of mind, energy of mind, is largely this function.

It is this which adapts us to different situations, different groups, by calling into play organized modes of talking or acting. We pa.s.s from a group of ladies in whose presence we have been friendly but decorous, perhaps unconventionally formal, to a group of business intimates, men of long acquaintance. Without even being conscious of it we lounge around, feet on the table, carelessly dropping cigarette ash to the floor, using language chosen for force rather than elegance; we discuss sports, women, business and a whole group of different emotions, habits and purposes come to the surface, though we were not at all conscious of having repressed them while in the presence of the ladies. A faux pas is where the organizer has "slipped" on his job; lack of tact implies in part a rigid organizing energy, neither plastic nor versatile enough.

We are now ready to face certain developments of these three main factors, viz., the response to stimuli; choice and inhibition, and the organizing energy. Largely we might cla.s.sify people according to the type of vigor of their reactions to stimuli, the quality and vigor of choice and of inhibition, and the quality and vigor of the organizing energy. We note that there are people who have, as it were, exquisitely sensitive feelers for the stimuli of one kind or another and who react vigorously, perhaps excessively; that there are others of a duller, less reactive nature, largely because they are stimuli-proof. Others are under-inhibited, follow desire or outer stimulus without heed, without a brake; others are over-inhibited, too cautious, too full of doubt, unable to choose the reaction that seems appropriate. The organizing energy of some is low; they never seem to unify their experiences into a code of life and living; they are like a string of beads loosely strung together with disharmonious emotions, desires, purposes. In others this energy is high, they chew the cud of every experience and (to change the metaphor) they weld life's happenings, their memories, their emotions and purposes into a more unified ego, a real I, harmonious, self-enlightened; clearly conscious of aim and end and striving bravely towards it. Or there is over-unification and fanaticism, with narrow aim and little sympathy for other aims.

Sketched in this very broad way we see ma.s.ses of people, rather than individuals, and we are not finely adjusted to our subject.

Psychologists rarely concern themselves to any extent with these matters; they deal mainly with their outgrowths,--emotions, instinct, intelligence and will. We are at once beset with difficulties which are resolved mainly by ignoring them. In such a book as this we are not concerned with the fundamental nature of these divisions of the mental life, we must omit such questions as the relation of instinct to racial habit, or the evolution of instinct from habit, if that is really its origin.

Again I must repeat that we shall deal with these as organic, as arising in the sensitized individual as a result of environmental forces, as manifestations of a life which is as yet--and perhaps always will be--mysterious to us. We shall best consider these manifestations of mental activity as an interplay of the reactions of stimulation, inhibition, choice, organizing energy, and not as separate and totally different matters. We shall see that probably emotion is one aspect of reaction to the world, while instinct is merely another aspect; that intelligence is a cerebral s.h.i.+ft of instinct, and that will is no unity but the energy of instincts and purposes.

Before we go farther we must squarely face a problem of human thought. Man, since he started reflecting about himself, has been puzzled about his consciousness. How can a person be aware of himself, and what identifies and links together each phase of consciousness? There is an enormous range of thought on this subject: from those who identified consciousness as the only reality and considered what the average person holds as realities--things and people--as only phases of consciousness, to those who, like Huxley, regard consciousness as an "epi-pbenomenon," a sort of overture to brain activity and having nothing whatever to do with action, nothing to do with choice and plan, so that, as Lloyd Morgan points out, "An unconscious Shakespeare writes plays acted by an unconscious troupe of actors to an unconscious audience." The first extreme view, that of Berkeley and the idealists, nullifies all other realities save that of the individual thinker and reduces one to the absurdities of Solipsism where a man writes books to convince persons conjured up by himself and having no existence outside of himself; the other view nullifies that which seems to each of us the very essence of himself.

I shall take a very simple view of consciousness,[1] simply because I shall deliberately dodge the great difficulties.

Consciousness is the result of the activities of a group of more or less permanently excited areas of the brain--areas having to do with positions of the head, eyes and shoulders; areas having to do with vision, hearing and smell; areas having to do with speech,--these const.i.tuting extremely mobile, extremely active parts of the organism. From these consciousness may irradiate to the activities of almost every part of the organism, in different degrees. We are often extremely conscious of the activities of the hands, in less degree of the legs; we may become wrapped up almost completely in a sensation emanating from the s.e.x organs, and under fear or excitement the heart may pound so that we feel and are conscious of it as ordinarily we can never be. The state of consciousness called interest may s.h.i.+ft our feeling of self to any part of our body (as in pain, when a part usually out of consciousness swings into it, or when the hand of a lover grips our own so that the great reality of our life at the moment seems to be the consciousness of the hand) or it may fasten us to an outside object until our world narrows to that object, nothing else having any conscious value. This latter phenomenon is very striking in children; they become fascinated by something they hear or see and project themselves, as it were, into that object; they become the "soapiness of soap, or the wetness of water" (to use Chesterton's phrase), and when they listen to a story they hold nothing in reserve. Consciousness may busy itself with its past phases, with the preceding thought, emotion, sensation --how, I do not know--or it may occupy itself mainly with the world of things which are hereby declared to have a reality in our theory. In the first instances we have introspection and subjectiveness, and in the second we have extroversion and objectivity.

[1] For discussion of consciousness read Berkeley, Locke, Hume, Spencer, Lotze, Moyan, James, Wundt, Munsterberg and every other philosopher and psychologist. I have not attempted to discuss the matter from the philosopher's point of view for the very obvious reason that I am no philosopher.

Since consciousness is most intense when the new or unfamiliar is seen, heard, felt or attempted, we may a.s.sume it has a chief function in acquainting the individual with the new and unfamiliar and in the establishment of habitual reactions, We are extraordinarily conscious of a queer, unexplainable thing on the horizon, we bring into the limelight (or IT brings into the limelight) all our possible reactions,--fear, flight, anger, fight, circ.u.mvention, curiosity and the movements of investigation; we are thrown into the maelstrom of choice. Choice and consciousness, doubt and consciousness, are directly related; it is only when conduct becomes established as habit, with choosing relegated to the background, that consciousness, in so far as the act is concerned, becomes diminished.

A moderate constant sensation tends to disappear from consciousness, as when we keep our hand in warm water. It then takes a certain increase of the stimulus to keep the sensation from lapsing out of consciousness. This lapsing out of consciousness of the steady stimulus, in its ramifications, is responsible for a good deal of the activity of man, since sensation is a goal of effort.[1] Under emotion we become aware of two sets of things,--the reaction of our body in its sum total of pleasure or the reverse, and second the object that sets up this reaction. Consciousness fastens itself on the body and on the world, and the bodily reaction becomes a guide for future action. Extreme bodily reactions are painful and may result in the abolis.h.i.+ng of consciousness.

[1] The physiologists speak of this phenomenon under the heading of the Weber-Fechner law, after the two physiologists who gave it prominence. James pokes a good deal of fun at the "law," which is expressed mathematically. Perhaps the mathematics should have been eliminated as too "scientific" for our present attainment, but it does remain true that it is not the ACTUAL stimulus increase that is important in sensation or perception, but the RELATIVE stimulus increase. This is behind all of "getting used to things"; it removes the pain from humiliation and also the novelty from joy. It is the reason behind all of the searching for novelty and excitement.

We a.s.sume that consciousness is organic, though we concede that it may be true that it is borrowed from a great pool of consciousness[1] out of which we all come. Consciousness IS organic because a blow on the head may abolish it as may drugs and disease, or a s.h.i.+fting of the blood supply as in emotion or fatigue in the form of sleep, etc. Where does it go to and how does it come back? The savage answered that question by building up the idea of a soul, a thing that might migrate, had an independent existence, took journeys in the form of dreams and lived and flourished after death. Most of these ideas still persist, perhaps as much through the fear of annihilation as anything else, but as to whether or not they are true this book does not concern itself. We have no proof of these matters, but we can prove that we can play on consciousness as we play on a piano, through the body and brain. A blow injures groups of nerve cells and consciousness disappears; when they recover, it returns. Where does any function go when structure is injured? We have practically the same kind of proof for the position of consciousness as a function of the brain and body that we have for gastric juice as a secretion of gastric cells.

[1] Even if it were true that consciousness is the only reality, n.o.body really believes it in that n.o.body acts as if it were true.

Conversely, everybody acts as if trees, rocks, and people were realities; as if fatigue, sickness, age, etc., affected consciousness. That is why, in this book, we are discarding as irrelevant the "ultimate" truth concerning consciousness. My humble belief is that the ultimate truth in this matter will never concern us because we shall never know it.

However widely we spread the function of consciousness and its domain, we still leave a large field of activities untouched. And so we come to the conception of the subconsciousness. There are two prevailing sets of opinions concerning the subconscious.

The first is quite matter-of-fact. It states that the movements and activities of a large part of the body are outside of the realm of consciousness, such as the activities of the great viscera--heart, lungs, intestines, liver, blood vessels, s.e.x glands--and are largely operated by the vegetative nervous system.[1] There are influences pouring into the brain from these organs, together with influences from muscles, joints, tendons, and these influences, though not consciously itemized, are the subconsciously received stimuli which give us feelings of vigor, energy, courage, hopefulness, or the reverse, according to the state of the organism. In health the ordinary result of these stimuli is good, though people may have health in that no definite disease is present, and yet there is some deficiency in the energy-arousing viscera which brings a lowered coenesthesia, a lessened vigor and lowered mood. In youth the state of the organs brings a state of well feeling; in old age there is a constant feeling of a low balance of energy and mood, and the person is always on the verge of unpleasant feeling. In the great change periods of life--at p.u.b.erty and the climacteric (or the menopause)--the sudden change in the activity of the s.e.x organs may produce great alterations[2] in the coenaesthesia and therefore in the energy and mood of the individual.

[1] This is not the place to describe the vegetative nervous system. (It was formerly called the sympathetic nervous system, but this term is now limited to one part of this system, and the term autonomic to another part, although some writers still use the term sympathetic for the whole, and others [the English] the term autonomic for the whole.) This system is the nervous mechanism of organic life, regulating heart, lungs, blood vessels, intestines, s.e.x organs, acting together with endocrines, etc. A huge amount of work has been done of late years on this system and we know definitely that it stimulates, inhibits and regulates these organs, and also that it records their activities. We are commencing to believe that this system is fully as important, in mental life, as the brain. See Langley, Schaeffer, Higier, etc.

[2] This is especially true of the menopause in women, and often enough of each menstrual period. That there is a climacteric in men is not so clear, but something corresponding to it occurs, at least in the case of some men.

In addition, these activities, which are so all-important, determine the basic conduct by arousing the basic appet.i.tes and desires of the individual. It is the change in the gastro-intestinal tract and in the tissues of the body that starts up the hunger feeling and the impulses which prompt men to seek food; in other words, this type of coenaesthesia has set going all the physical and mental activities relating to food; it is the basic impulse behind agriculture and stock raising, as well as energizing work activities of all kinds. It is the tension in the seminal vessels of the male that wakes up his pa.s.sion, if it is not the sole source of that pa.s.sion. s.e.x desire in the adult male has many elements in it, not pertinent at present, but the coenaesthetic influence of the physical structures is its starting point. In men as well as women there is a cycle of desire, with height due to physical tension and abyss following the discharge or disappearance of tension, that profoundly influences life and conduct. Here the sympathetic nervous system and the internal secretion of the genital glands awaken into s.e.xual activity brain, spinal cord and muscles, so that the individual seeks a mate, plunges into marriage and directs his conduct, conscious of taste and desire, but largely unconscious of the physical condition that is impelling him on.

In this sense the subconscious activities dominate in life, because the functions of nutrition and reproduction are largely unconscious in their origin, but there is no organized, plotting subconsciousness at work.

Once a thing is experienced, it is stored in memory. What is the basis and position of a memory when we are not conscious of it, when our conscious minds are busy with other matters? What happens when a desire is repressed, inhibited into inaction; when consciousness revolts against part of its own content? Is a "forgotten" memory ever really lost, or a desire that is squelched and thrust out of "mind" really made inactive? Do our inhibitions really inhibit, or do we build up another self or set of selves that rise to the surface under strange forms, under the guise of disease manifestations?

Sigmund Freud and his followers have made definite answers to the foregoing, answers that are incorporated in a doctrine called Freudianism. Freud is an Austrian Jew, a physician, and one that soon specialized in nervous and mental diseases. Early in his career he did some excellent work in the study of the paralysis of childhood (infantile hemiplegia), but his attention and that of an older colleague, Breuer, were soon drawn (as has occurred to almost every neurologist) to the manifestations of that extraordinary disease, hysteria. Hysteria has played so important a role in human history, and Freud's ideas are permeating so deeply into modern thought that I deem it advisable to devote a chapter to them.

CHAPTER V. HYSTERIA, SUBCONSCIOUSNESS AND FREUDIANISM

Hysteria was known to the ancients and in fact is as old as the written history of mankind. Considered essentially a disease of women, it was given its present name which is derived from "hysteron," the Greek name for the womb. We know to-day that men also are victims of this malady, though it arises under somewhat different circ.u.mstances than is the case with the other s.e.x. Men and women, living in the same world and side by side, are placed in greatly different positions in that world, are governed by different traditions and are placed under the influences of differing ambitions, expectations, hopes and fears. Hysteria arises largely out of the emotional and volitional reactions of life, and these reactions differ in the s.e.xes.

It was a group of French neurologists, headed by Charcot--and including very ill.u.s.trious men, such as Janet and Marie, who paid the first scientific attention to the disease. Under their a.n.a.lyses hysteria was defined as a mental disease in which certain symptoms appeared prominently.

1. Charcot especially paid attention to what are known as the attacks. The hysteric patient (usually a woman, and so we shall speak of the patient as "she") under emotional stress and strain, following a quarrel or a disagreement or perhaps some disagreeable, humiliating situation, shows alarming symptoms.

Perhaps she falls (never in a way to injure herself) to the floor and apparently loses consciousness, closes her eyes, rolls her head from side to side, moans, clenches her fists, lifts her body from the floor so that it rests on head and heels (opisthotonic hysteria), shrieks now and then and altogether presents a terrifying spectacle. Or else she twitches all over, weeps, moans, laughs and shouts, and rushes around the room, beating her head on the walls; or she may lie or stand in a very dramatic pose, perhaps indicating pa.s.sion or fear or anger. The attacks are characterized by a few main peculiarities, which are that the patient usually has had an emotional upset or is in some disagreeable situation, that she does not hurt herself by her falls, that consciousness is never completely abolished and fluctuates so that now she seems almost "awake" and then she seems almost in a complete stupor, and that the expression of emotion in the attack is often very prominent. These symptoms are readily differentiated from what is seen in epilepsy.[1]

[1] The French writers of the school of Babinski deny that the above symptom and even the majority of the following have a real existence in hysteria. The English, American and German neurologists and the rest of the French school describe hysteria substantially as I am here describing it.

2. The hysteric paralyses which are featured in all the literatures of the world are curious manifestations and often very stubborn. Following an accident (especially in industry and in war) and after some emotional difficulty there is a paralysis of some part of the body. The arm or some particular part of the arm cannot be moved by the will, is paralyzed; or else the difficulty involves one or both legs. Sometimes speech is gone, or the power of moving the head; occasionally the difficulty is with one side of the face, etc. Usually the paralysis comes on suddenly, but often it comes on gradually. Modern neurology soon discovered that these paralyses were quite unlike those seen when there is "real" injury to the brain, spinal cord or the peripheral nerves. They corresponded to the layman's idea of a part. Thus a paralysis of the arm ends at the shoulder, a paralysis of the feet at the ankle, and in ways not necessary to detail here differ from what occurs when the organic structure of the nervous system is involved. For example, the reflexes in hysteria are unaltered, and stiffness when it occurs is not the stiffness of organic disease. If a neurologist were to have a hysteric paralysis a very interesting problem in diagnosis would be presented.

Further, the paralysis yields in spectacular fas.h.i.+on to various procedures or else disappears spontaneously in remarkable fas.h.i.+on overnight. Paralyses of this type have disappeared under hypnosis, violent electric shocks, "magical" liniments, threats, prayers, the healer's, the fakir's, the doctor's personal influence; under circ.u.mstances of danger (a fire, a row, etc.); by pilgrimages to Lourdes, St. Anne de Beaupre, the Temple of Diana, the relic of a saint; by the influence of sudden joy, fear, anger; by the work of the psychoa.n.a.lyst and by that of the osteopath! Every great religious leader and every savage medicine man beating a tom-tom has had to, prove his pretensions to greatness by healing the sick--so intensely practical is man--and he has proved his divinity by curing the hysterics, so that they threw away their crutches, or jumped blithely out of bed, or used their arms, perhaps for the first time in years. Hysteria has caused more talk of the influence of mind over body than all other manifestations of mental peculiarity put together. Wherever there is anything to be gained by hysteric paralyses, these appear in much greater frequency than under ordinary circ.u.mstances. Thus the possibility of recovering damages seems to play a role in bringing about a paralysis that defies treatment until the litigation is settled; similarly the possibility of being removed from the fighting line played a large part in the causation of war hysteric paralysis.

3. A group of sensory phenomena is conspicuous in hysteria, sometimes combined with the paralyses and attacks but often existing alone. A part of the body will become curiously insensitive to stimulation. Thus one may thrust a pin into any part without evoking any pain and APPARENTLY without being felt; one may rub the cornea of the eye, that exquisitely sensitive part, without arousing a reaction; one may push a throat stick against the uvula as it hangs from the palate without arousing the normal and very lively reflex of "gagging." These insensitive areas, known as stigmata, played a very important role in the epidemic of witchcraft hunting of the sixteenth and seventeenth centuries, when the witch was so diagnosed if she felt no pain when a needle was thrust into her. Mankind has often enough wors.h.i.+ped the insane and mentally aberrant and has as often been diabolically cruel to them.

What has been stated of the paralyses is true of the insensitive areas; they correspond to an idea of a part and not to an anatomical unit. Thus a loss of sensation will reach up to the wrist (glove type) all around, front and back, or to the elbow or the shoulder, etc. No organically caused anaesthetic area ever does this, and so the neurologist is able, usually, to separate the two conditions. And the anaesthesias yield as do the hysteric paralyses to a variety of agents, from prayer and persuasion to a bitter tonic or a blow. I confess to a weird feeling in the presence of a hysteric whose arm can be thrust through and through with a needle without apparently suffering any pain, and it seems to me that this may be the explanation of the fort.i.tude of those martyrs who have astonished and sometimes converted their persecutors by their sublime resistance to torture.

There has been described as part of hysteria the hysteric temperament. The characteristics of this temperament are the emotional instability, the strong desire for sympathy, the effort to obtain one's desire through weakness, through the appeal to the sympathy of others, an irritable egoism never satisfied and without firm purpose. It is true that the majority of peace-time hysterics show this peculiar temperament, but it is also true that the war-time hysterics often enough were of "normal"

character, without prior evidence of weakness.

As I before mentioned, Freud became greatly interested in this group of patients and especially in the female patients, since in ordinary neurological practice the male hysteric is not common.

Out of his experience and effort he built up a system of beliefs and treatment, the evolution of which is interesting, but which is not here important.

At the present time the Freudian doctrine hangs on the following beliefs:

1. That from the beginning to the end of life everything in the mental activities of man has a cause and a meaning, and that these causes and meanings may be traced back to infancy. No slip of the tongue is accidental; it has purpose and this purpose can be traced by psychoa.n.a.lysis. So with hysteric phenomena: the paralyses, the sensory changes, all the queer and startling things represent something of importance and of value to the subconscious.
