The Glands Regulating Personality Part 18

Natural ability grows in an endocrine soil of a particular kind, perhaps affected by the internal secretions much as natural soil is by fertilizers like phosphates or nitrates. Increased production follows increased fertilization. Natural disability must vary similarly with a perversion or improper mixture, deficiency or absence of the hormones that combine in natural ability.

It is a.s.sumed as a matter of course that the brain itself is there, which, to carry out our a.n.a.logy, means that the crude soil or earth is there. Sufficient quant.i.ty and adequate quality of nerve tissue must be regarded as prerequisite. If the brain has been damaged in any way during development or birth, if it has been smashed up in any way, or if it has failed to evolve the minimum number of healthy nerve cells, the endocrine influence becomes negligible. It is like attempting to insert a key into a door which has no lock.

It is among the specimens of normality of the brain cells that we may look for our examples of endocrine mental deficiency. Included are all sorts of examples of feeble-mindedness varying from the moron to the imbecile and idiot, arrested brain life. The cretin is the cla.s.sic type of mental deficiency due to endocrine insufficiency, curable or improvable by the proper handling.

Insanity, degeneration of the normal brain life, may be caused by an upset of the endocrine balance. Among the commonest manifestations of insanity are excitements and depressions, apathies and manias, hallucinations, delusions and obsessions, all of which are reproducible under known conditions of internal secretion excess or failure. Alternating states of mania and depression are caused in some instances by extreme hyperthyroidism. The critical periods of life, when a profound revolution is overturning the endocrine equilibrium, p.u.b.erty, pregnancy, and the menopause, are the periods of most frequent occurrence of insanity, when mental instability reveals endocrine instability (Dementia praec.o.x, pregnancy psychosis, menopause neurosis). Actual insanity need not be the only manifestation. By far the greater number of mental disturbances due to aberrations of the internal secretions never see an asylum or a doctor. They live more or less close to the borderline of insanity as persons who have spells, eccentricities and peculiarities, hysteria, tics or just "nervousness."

About two-thirds of mental deficiency is definitely inherited, about one-third acquired. It is the opinion of a number of psychologists that it is inherited as what the Mendelians call a recessive, that is as a trait which will be overshadowed, if there is admixture of normal mentality, but will crop up by breeding with another mental defective.

What we know of the endocrine factors in heredity leads us to suppose that it is the mating of one marked endocrine insufficiency with another that is often responsible for the inherited tendency to feeble-mindedness and insanity. The effect of the hormone system upon the vegetative apparatus may create the more obscure insanities and quasi-insanities. The direct action of the internal secretions upon the brain cells, producing a sort of hair trigger situation within them, may cause the explosive discharges from them which appear as overpowering impulses or uncontrollable conduct. The waves of feeling which precede them are unquestionably endocrine determined. The wave of fear a cat experiences upon seeing a dog is accompanied and indeed preceded by an increase of the amount of adrenalin in the blood. The picture of fright, as observed in a so-called normal person, staring eyes, trembling hands, dry lips and mouth, corresponds to the portrait of the appearance in hyperthyroidism. In persons afflicted with uncontrollable impulses, the inhibiting hormones may not be present in sufficient quant.i.ty.

Feeble-mindedness, ranging from stupidity to imbecility, may also be a direct effect of insufficient endocrine supply to the brain cells.

When there is not enough of the thyroid secretion in the blood, the tissue between the cells in the brain become clogged and thickened, so that a gross barrier to the pa.s.sage of the nerve impulses is created.

We have here an ill.u.s.tration of internal secretion lack actually producing gross changes in the brain. But without a doubt, most endocrine influences upon the brain, at work every minute and second of its life, are the subtle ones of molecular chemistry and atomic energetics. We know that such mental qualities as irritability and stupidity, fatigability, and the power to recover quickly or slowly from fatigue, s.e.xual potency and impotence, apathy and enthusiasm are endocrine qualities. We know also that the thyroid dominant tends to be irritable and excitable, the pituitary deficient to be placid and gentle, the adrenal dominant to be a.s.sertive and pugnacious, the thymus-centered to be childish and easy-go-lucky and the gonad deficient to be secretive and shy. This brings us to the relation of the internal secretions to the type of personality as a whole.

CHAPTER X

THE TYPES OF PERSONALITY

THE ENDOCRINE PERSONALITY

If a single gland can dominate the life history of an individual it becomes possible to speak of _endocrine types_, the result of the _endocrine a.n.a.lysis_ of the individual. Studying endocrine traits of physique, life reactions, disease tendencies, hereditary history and blood chemistry, one may gain an insight into the composition or const.i.tution of an individual. The endocrine type of an individual is a summary of these, his behaviour in the past, and is also a prediction of his reactions in the future, much as a chemical formula outlines what we believe to be the skeleton of a compound substance as deducible from its properties under varying conditions. Only, admittedly, as yet the endocrine label is but roughly qualitative and most crudely quant.i.tative, whereas the chemical formula is the essence of the exact.

However, the fact remains that though we are only upon the first rungs of the ladder, we are upon the ladder. The horizon undoubtedly broadens. We possess a new way of looking upon humanity, a fresh transforming light upon those strange phenomena, ourselves. Of the ugly achievements of that dreadful century, the nineteenth, the most illuminating was the discovery of itself as the _ape-parvenu._ Yes, we are all animals now, it said to itself, and set its teeth in the cut-throat game of survival. But there was no understanding in that evil motto of a disillusioned heart. The ape-parvenu, desperately lonely and secretive, has still to understand himself.

Let us be clear if we can. There is perhaps a certain presumption in the phrase, the endocrine type. It is ambitious, and perhaps will not fulfill its promise. But it is useful because it points a parallel and an ideal. As Wilhelm Ostwald never tired of repeating, H_{2}O is a complete shorthand record for the bundle of qualities commonly known as water. It is an example of that highest task of mind, synthesis.

It is the highest synthesis of the studies of the internal secretions that certain combinations of them, permutations and blendings of them, are responsible for those unique wonders of the universe, personalities.

The riddle of personality! Are we at last upon the track of its uncovering? That elusive mystery, which philosophers have wrapped in the thousand veils of Greek and Latin words, and psychologists, even unto the third and fourth generation of Freudians, have floundered about in, moles before a dazzling sun, is it to be unwound for our inspection? Think of the human soul. What an invisible, intangible chameleon is its true reality! Watch it, and you see something that seems to uncurl and expand like a feather with exultation and delight and joy, to contract and stiffen into a billiard ball with fear and pride, shrewd caution and vigilant malevolence, to rear back and spark fire like lightning with anger and temper, and to crawl and slither with abjection and smirking slyness, when it needs to. This multiplex Thing-Behind-Life, are we really about to dissect it into its elements?

Personality embraces much more than merely the psychic attributes. It is not the least important of the lessons of endocrine a.n.a.lysis that there is no soul, and no body, either. Rather a soul-body, or body-soul, or the patterns of the living flame. The closer tracking of the internal secretions leads us into the secrets of the living flame, why it lives, and how it lives, the strange diversities of its colorings and music and the odd variations in its energy, vitality and longevity. Why it flickers, why it flares and glares, spurts, flutters, burns hard or soft, orange-blue or yellow.

The medieval scholiasts, who fought as fiercely about names as nations about territories, divided men into the sanguine, the bilious, the lymphatic and the nervous. It was a pretty crude cla.s.sification of different const.i.tutions. The endocrine criteria, more exact and concrete, divide them into the adrenal centered, the thyroid centered, the thymus centered, the pituitary centered, the gonad centered, and their combinations.

THE ADRENAL PERSONALITIES

An adrenal personality is one dominated by the ups and downs of his adrenal gland. In the large, the curve of his life is the curve of secretion by this gland, both of its Cortex and medulla. Such an adrenal personality is entirely normal, within the definition of the normal as something not threatening the duration of life, nor comfortable adaptation to it. So are the other glandular types. No sharp line can be drawn between the normal and the abnormal in any case, the borderland is wide, the transitions many.

The skin is one of the chief clues to the adrenal personality. The relation between the adrenal and the skin dates way back in the evolutionary scale, for adrenalin has been isolated directly from pigment deposits in the epidermis of frogs. Skin pigment bears a direct relation to the reaction of the organism to light, especially the ultraviolet rays, to the radiation of heat, and hence to the fundamental productions and consumptions of energy by the cells. So the gland of energy for emergencies writes its signature always all over the skin.

In an adrenal personality, the epidermis is always slightly, somewhat, or deeply pigmented. The pigmentation is due to a dark brown deposit lightly or thickly scattered over the skin. With the general diffuse pigmentation or darkening there are often the black spots, the pigmented birth marks, or the lighter ones of freckles. The latter signify some permanent or transitory adrenal inadequacy in the past, ante-natal or post-natal, of the individual, and presage the same in his future. These spots have been frequently observed to appear after an attack of diphtheria or influenza. There seems to be more tuberculosis among those who have them than those who do not. We therefore say that diphtheria, influenza and tuberculosis stand out as adrenal-attacking diseases, which have a greater power to kill, cripple or hurt those with defective adrenal const.i.tutions than others.

The hair of the adrenal type is characteristic: ubiquitous, thick, coa.r.s.e and dry. It is prominent over the chest, abdomen and back, and has a tendency to kink. Often its color is not the expected: an Italian's will be yellow, a Norwegian's jet black. It has been stated that most red-haired persons are adrenal types. Such persons also have well-marked canine teeth which is another adrenal trait. They also have a low hair line.

When the adrenal type has a properly co-operating pituitary and thyroid, he possesses a striking vigor, energy and persistence. With a fortunate combination, he develops into a progressive winning fighter, arriving at the top in the long run every time.

Brain work is pretty well lubricated in the well-compensated adrenal type. Brain f.a.g is closely a.s.sociated with, if not dependent upon, adrenal f.a.g, particularly of the cortex. Brain tissue and adrenal cortex tissue are near relatives, and a normal human brain never develops without a normal adrenal cortex. The adrenal type with an hypertrophied adrenal cortex is always efficient.

Among women, the adrenal type is always masculinoid. If physically feminine--due to adequate feminine reactions on the part of the other endocrines--she will at least show the qualities of a psychic virilism. A generation ago, such a woman had to repress her inherent trends and instincts in the face of public opinion and law, and so suffered from a feeling of inferiority. Nowadays, these women are striding forward and will attain a good many of the masculine heights, commanding responsible executive positions and high salaries. An adrenal type will probably be the first woman president of the United States.

However, that presupposes a normal range of action of the other endocrines. Let there be some quirk or weakness elsewhere in the chain of hormones, and instead of the successful woman, behold the spinsters, the maiden aunts, the prudes and cranks who never satisfactorily adapt themselves in society. To them must be given a good deal of credit for the suffrage revolution. These unadapted adrenals, as we may call them, once sowed the seeds, expending their masculinism in the struggles of the pioneers' martyrdoms, preparing the harvest their sisters, the more adequate adrenal types, will now reap. The unadapted adrenals of today will have to look for new worlds to conquer.

So much for the compensated adrenal types. They are the good workers, the efficients, the kinetic successes of the driven world. They make, at a certain level, good slave drivers because they feel within themselves a driving force. But suppose the adrenal type becomes uncompensated, or perhaps is inadequate to the demands of life to start with. Then the story becomes different. The perfect efficient superman of business or profession begins to lag. Though he is himself in the morning, he begins to lag in the afternoon. That is when he tires. In the evening he is all in. More sleep, recreational trips, vacations slip into the rank of necessities, whereas previously they had been laughed at as luxuries. More minute or large moles emerge in the skin, especially if the individual is of a fair type. If a strenuous effort is not made to give the adrenals an opportunity to recuperate, or if adjustment on the part of the other glands does not occur, this stage of intermittent and remittent adrenal inadequacy gives way in turn to the state of permanent adrenal insufficiency.

The adrenal insufficient is important because he is to be seen everywhere. Built along the same lines as the adrenal adequate and apt to be taken for him, he differs and contrasts vividly below the surface. One may sum him up by saying that he is one variety of neurasthenic, perhaps the most frequent variety. Cold hands and feet plague him, cold feet psychically as well as physically, for a chronic and obsessive indecision is one of his most prominent complaints.

A fatigability, that goes with a low blood pressure, lowered body temperature and a disturbed ability to utilize sugar for fuel purposes, is another of his chief complaints. The skin often presents an instability of the blood vessels, so that they now react to stroking with a blanched instead of a reddened effect. Irritability, a liability to go off the handle at the slightest provocation, and a consequent complete exhaustion that, after an outburst, sends him to bed, is conspicuous. Dismissed sometimes contemptuously as weaklings, they are accused of laziness, craziness, and haziness. In their psychic attempts to compensate, they land into all kinds of hot water, from which friends, relatives or luck extricate them sometimes. The other times they go to the wall.

The congenital adrenal deficient is a special problem. If the history of such an individual is followed from birth, one gets a pretty typical story. The genealogy is nervous. Nervous is a word of many meanings. But when parents confess themselves nervous, it generally means a mental and emotional instability of some sort. Sometimes the idea is camouflaged as high strung. In the feeding narrative of the child, one finds not occasional incidents or episodes, but continued trouble, difficulties, adventures. Even after the first year or two, the nutritional chronicle is not satisfactory. Lack of appet.i.te, lack of energy, lack of response to stimuli are its keynotes and the motifs of the later years of childhood.

Growth is a strain. It becomes a task to make these children grow and gain. Chronically below the average weight and height, herculean efforts are made by the conscientious parents, but with small success.

With the entry of school life and compet.i.tion, the curtain rises upon the real tragedy, a tragedy in which the avenging Fates are the usual ignorance, stupidity and misunderstanding. If the teachers alone are duty-obsessed, or perhaps s.a.d.i.s.tic, the child endures the agonies of repeated admonitions, demotions, and punishments. However, a certain thick-skinned indifference may develop to protect the sufferer.

If the parents are in addition ambitious, or proud, or compet.i.tive, then woe betide the victim. With their nervous dispositions, it is the school and the tutor who are to be blamed, if not the child. From school to school, from system to system, from novelty to fad, from doctor to doctor, from fakir to charlatan, from pillar to post, they wander in search of an education. Educational cults by the dozen have sprouted and grown fat around these unfortunates.

The chief defect of the congenital adrenal inadequate is an insufficiently developed adrenal cortex. That means an insufficiently developed brain and nervous system. For we have seen how closely all these are related in development. Now education can never be the education of a vacuum. And we have to deal here with a relative vacuum. When there are no potentialities, there can be no education.

Where the potentialities are limited, education must be limited.

The congenital adrenal inadequate is defined in physical and mental energy. Hence educators cannot drive him. Up to a certain point he can be led, but no farther. He should not be expected to go to a college, and waste the opportunity of some one financially unlucky, but whose endocrine system is more generously endowed.

Not that the outlook is absolutely hopeless. p.u.b.erty, with its tremendous changes in the glands of internal secretion, when one can almost hear the clicks and the whirring of the wheels in the internal machinery, may transform. The unfathomed possibilities of gland therapy are still to be probed. But the general rule remains.

THE REACTIONS TO MODERNISM

The adrenal personalities in all their variations must be safeguarded and carefully looked after in the strained complexities of modern post-bellum civilization. In a sense, the adrenal type is the Atlas of the twentieth century world, and small wonder that he and his descendants stagger beneath the burden. The adrenals are organs for the mobilization of energy, physical and mental, for emergencies. They are the glands which meet shocks and neutralize the effects of shock.

In the solitary animal, the everyday producers of shock are pain, fright and wounds. The adrenal mechanisms oversecrete to encounter the enemy, and then there is a period of rest and recuperation. Man, however, with the growth of his imagination and the increase in number and density of his surrounding herd, has become the subject of continuous stimulation. In the past, this was balanced by the almost universal dominance of some religious belief, as an effective opiate.

Concepts like Fate, Predestination, an all-guiding and all-wise Providence, relieved and shielded the adrenals, and acted as valuable adjuvants for the preservation of normality.

The nineteenth century witnessed the birth and expansion of a great number of new stimulant reagents, the discoveries of physics and chemistry, which, with the climax of the World War of 1914-1918, have made for a more or less complete deliquescence of accepted religion.

For the great majority there was no faith to take its place. War, pre-war, and post-war shocks have continued with their incessant pounding upon the reserves of energy. Under these conditions the adrenal personalities are bound to suffer. The other endocrine types suffer, too, but quite differently.

Today, anti-adrenal, anti-religious ideas are epidemic. Of these, first prize belongs to a cult of egotism fathered by the Napoleonic Idea, consciously a.s.sertive and self-conscious in Max Stirner's "The Ego and His Own," which engendered a swarm of imitators and plagiarists. Human beings are all incorrigible egoists more or less, furtive or frank. But social and religious codes curbed the most narcissistic of kings and conquerors. Before Napoleon, all of them vowed allegiance and expressed submission to some sort of deity, confessed some fear of the Lord in their hearts. But the ideas of Napoleon flouted all that. The unscrupulous predatory who put effectual scheming for the self plainly above every other consideration and rode rough shod over all his fellows appealed powerfully to the latent animality of the adrenal types. Then came the dawning awareness of capital and labor of themselves as cla.s.ses fiercely opposed forever in the policy of cut-throat versus cut-throat. The labor organizations and the commercial companies and corporations pitted themselves against each other consciously.

Doctrines like "Property is but Robbery," "Everyone for himself and the devil take the hindmost," the "Iron Law of Wages" and the "Facts is Facts" of the Gradgrinds were the phrases of the nineteenth century that a.s.sisted. Finally came the Darwinian revelation of man as the ape-parvenu, which completed the disintegration of the old restraints.

Man seemed to see himself now for the first time stark and naked. But Man consists of many varieties, and all reacted differently to the image in the clouded mirror. There was universal attempt at suppression. But slowly the anti-adrenal forces infiltrated every activity and every soul. Like a hidden focus of infection in the body, it germinated and poisoned. A slow fever crept into life. A febrile quality tinged the acquisition of wealth, the concentration upon s.e.x, and the desperate pursuit of the novel stimulus.

Then, like the hand that appeared at Belshazzar's Feast, came the War, only it was a hand that stayed with a long flashing lightning sword in its grip, sweeping pitilessly among the erstwhile dancing mult.i.tudes to mutilate and destroy. A good many people, with that st.u.r.dy animality George Santayana speaks somewhere of as a trait of mankind, set out to enjoy the War. It was a new sort of good time upon an incredibly large scale. It was an undreamed-of opportunity. The mechanisms of suppression of the mind render it incapable of appreciating horror until encountered. And so thousands with dangerously unstable adrenals were plunged into the most trying conditions possible. Hundreds of them, already shaken, on the borderland of instability, reacted with the phenomena of breakdown of control, lumped with a host of other phenomena, under the general rubric of "sh.e.l.l shock."

That alone was not all. If hundreds collapsed, thousands approached the verge of collapse. They survived and were discharged from the armies as normal. They reappear in civil life as cases of "nerves."

Ordinarily that would mean that they would be cla.s.sed as failures. But such have been the psychologic reactions to the war that all kinds of compensations in the way of dangerous mental states have become frequent in these inadequate adrenal types. A trend to violence and a resentful emotionalism are combined with desperate attempts to spur the jaded adrenals with artificial excitements. Consequent melancholia and depression, the "blues," are inevitable. A survey of drug addicts would probably show a definite percentage of this type. The same applies to certain petty criminals and law breakers.

The adrenal element in the personality must be considered in every disturbance, morbid, personal, or social involving brunette types, Huxley's dark white, Mediterranean-Iberians, red-haired persons, and even pigment-spotted fair people. Historians have traced the earliest civilization to the doings of a brunette people, the Sumerians, the first to build cities in the Euphrates-Tigris region more than five thousand years before Christ was born. An adrenalized people one would, expect to be the first to take advantage of possibilities because of their energy capacity. The earliest Sumerian stone carvings of warriors exhibit an undersized skeleton compared with the large head, broad face, a low hair line and prominent nose that would fit into the ensemble of the adrenal type. Certain other historical aspects of the adrenal personality have yet to be worked out.

THE PITUITARY PERSONALITIES

The presence of two antagonistic elements in the one gland complicates any attempt at even the most abstract a.n.a.lysis of a personality dominated by that gland. The pituitary, composed of an anterior lobe and posterior lobe, supplies two fairly uncomplicated corresponding types, best described as the masculine pituitary type, and the feminine pituitary type. The masculine pituitary type is one determined by the rule of the anterior pituitary, representing superlative brain tone and action, good all-around growth and harmonious general function, the ideal masculine organism. The feminine pituitary type has an excess of post-pituitary, with susceptibility to the tender emotions, sentimentalism, and emotionalism, feminine structural lines. Ante-pituitary dominance in a male reinforces the general masculinity while the post-pituitary depresses it. The post-pituitary in a woman augments her natural trend, ante-pituitary tending to counteract it. In other words, post-pituitary and ovary are conjunctive, ante-pituitary and ovary are disjunctive, post-pituitary and testis are opponents, ante-pituitary and testis are allies.
