The Foundations of Personality.

by Abraham Myerson.

INTRODUCTION

Man's interest in character is founded on an intensely practical need. In whatsoever relationship we deal with our fellows, we base our intercourse largely on our understanding of their characters. The trader asks concerning his customer, "Is he honest?" and the teacher asks about the pupil, "Is he earnest?"

The friend bases his friendship on his good opinion of his friend; the foe seeks to know the weak points in the hated one's make-up; and the maiden yearning for her lover whispers to, herself, "Is he true?" Upon our success in reading the character of others, upon our understanding of ourselves hangs a good deal of our life's success or failure.

Because the feelings are in part mirrored on the face and body, the experience of mankind has become crystallized in beliefs, opinions and systems of character reading which are based on physiognomy, shape of head, lines of hand, gait and even the method of dress and the handwriting. Some of these all men believe in, at least in part. For example, every one judges character to a certain extent by facial expression, manner, carriage and dress. A few of the methods used have become organized into specialties, such as the study of the head or phrenology, and the study of the hand or palmistry. All of these systems are really "materialistic" in that they postulate so close a union of mind and body as to make them inseparable.

But there are grave difficulties in the way of character-judging by these methods. Take, for example, the study of the physiognomy as a means to character understanding. All the physiognomists, as well as the average man, look upon the high, wide brow as related to great intelligence. And so it is--sometimes. But it is also found in connection with disease of the brain, as in hydrocephalus, and in old cases of rickets. You may step into hospitals for the feeble-minded or for the insane and find here and there a high, n.o.ble brow. Conversely you may attend a scientific convention and find that the finest paper of the meeting will be read not by some Olympian-browed member, but by a man with a low, receding forehead, who nevertheless possesses a high-grade intellect.

So for centuries men have recognized in the large aquiline nose a sign of power and ability. Napoleon's famous dictum that no man with this type of proboscis is a fool has been accepted by many, most of whom, like Napoleon probably, have large aquiline noses.

The number of failures with this facial peculiarity has never been studied, nor has any one remarked that many a highly successful man has a snub nose. And in fact the only kind of a nose that has a real character value is the one presenting no obstruction to breathing. The a.s.signed value given to a "pretty"

nose has no relation to character, except as its owner is vain because of it.

One might go on indefinitely discussing the various features of the face and discovering that only a vague relationship to character existed. The thick, moist lower lip is the sensual lip, say the physiognomists, but there are saints with sensual lips and chaste thoughts. Squinty eyes may indicate a shifty character, but more often they indicate conjunctivitis or some defect of the optical apparatus. A square jaw indicates determination and courage, but a study of the faces of men who won medals in war for heroism does not reveal a preponderance of square jaws. In fact, man is a mosaic of characters, and a fine nature in one direction may be injured by a defect in another; even if one part of the face really did mean something definite, no one could figure out its character value because of the influence of other features--contradictory, inconsistent, supplementary. Just as the wisest man of his day took bribes as Lord Chancellor, so the finest face may be invalidated by some disharmony, and a fatal weakness may disintegrate a splendid character. Moreover, no one really studies faces disinterestedly, impartially, without prejudice. We like or dislike too readily, we are blinded by the race, s.e.x and age of the one studied, and, most fatal of all, we judge by standards of beauty that are totally misleading. The sweetest face may hide the most arrant egoist, for facial beauty has very little to do with the nature behind the face. In fact, facial make-up is more influenced by diet, disease and racial tendency than by character.

It would be idle to take up in any detail the claims of phrenologist and palmist. The former had a very respectable start in the work of Broca and Gall[1] in that the localization of function in the various parts of the brain made at least partly logical the belief that the conformation of the head also indicated functions of character. But there are two fatal flaws in the system of phrenological claims. First, even if there were an exact cerebral localization of powers, which there is not, it would by no means follow that the shape of the head outlined the brain. In fact, it does not, for the long-headed are not long-brained, nor are the short-headed short-brained. Second, the size and disposal of the sinuses, the state of nutrition in childhood have far more to do with the "b.u.mps" of the head than brain or character. The b.u.mp of philoprogenitiveness has in my experience more often been the result of rickets than a sign of parental love.

[1] It is to be remembered that phrenology had a good standing at one time, though it has since lapsed into quackdom. This is the history of many a "short cut" into knowledge. Thus the wisest men of past centuries believed in astrology. Paracelsus, who gave to the world the use of Hg in therapeutics, relied in large part for his diagnosis and cures upon alchemy and astrology.

Without meaning to pun, we may dismiss the claims of palmistry offhand. Normally the lines of the hand do not change from birth to death, but character does change. The hand, its shape and its texture are markedly influenced by illness,[1] toil and care. And gait, carriage, clothes and the dozen and one details by which we judge our fellows indicate health, strength, training and culture, all of which are components of character, or rather are characters of importance but give no clue to the deeper-lying traits.

[1] Notably is the shape of the hand changed by chronic heart and lung disease and by arthritis. But the influence of the endocrinal secretions is very great.

As a matter of fact, judgment of character will never be attained through the study of face, form or hand. As language is a means not only of expressing truth but of disguising it, so these surface phenomena are as often masks as guides. Any sober-minded student of life, intent on knowing himself or his fellows, will seek no royal road to this knowledge, but will endeavor to understand the fundamental forces of character, will strive to trace the threads of conduct back to their origins in motive, intelligence, instinct and emotion.

We have emphasized the practical value of some sort of character a.n.a.lysis in dealing with others. But to know himself has a hugely practical value to every man, since upon that knowledge depends self-correction. For "man is the only animal that deliberately undertakes while reshaping his outer world to reshape himself also."[1] Moreover, man is the only seeker of perfection; he is a deep, intense critic of himself. To reach n.o.bility of character is not a practical aim, but is held to be an end sufficient in itself. So man constantly probes into himself--"Are my purposes good; is my will strong--how can I strengthen my control, how make righteous my instincts and emotions?" It is true that there is a worship--and always has been--of efficiency and success as against character; that man has tended to ask more often, "What has he done?" or, "What has he got?" rather than, "What is he?"

and that therefore man in his self-a.n.a.lysis has often asked, "How shall I get?" or, "How shall I do?" In the largest sense these questions are also questions of character, for even if we discard as inadequate the psychology which considers behavior alone as important, conduct is the fruit of character, without which it is sterile.

[1] Hocking.

This book does not aim at any short cuts by which man may know himself or his neighbor. It seeks to a.n.a.lyze the fundamentals of personality, avoiding metaphysics as the plague. It does not define character or seek to separate it from mind and personality. Written by a neurologist, a physician in the active practice of his profession, it cannot fail to bear more of the imprint of medicine, of neurology, than of psychology and philosophy. Yet it has also laid under contribution these fields of human effort. Mainly it will, I hope, bear the marks of everyday experience, of contact with the world and with men and women and children as brother, husband, father, son, lover, hater, citizen, doer and observer. For it is this plurality of contact that vitalizes, and he who has not drawn his universals of character out of the particulars of everyday life is a cloistered theorist, aloof from reality.

CHAPTER I. THE ORGANIC BASIS OF CHARACTER

The history of Man's thought is the real history of mankind. Back of all the events of history are the curious systems of beliefs for which men have lived and died. Struggling to understand himself, Man has built up and discarded superst.i.tions, theologies and sciences.

Early in this strange and fascinating history he divided himself into two parts--a body and a mind. Working together with body, mind somehow was of different stuff and origin than body and had only a mysterious connection with it. Theology supported this belief; metaphysics and philosophy debated it with an ac.u.men that was practically sterile of usefulness. Mind and body "interacted"

in some mysterious way; mind and body were "parallel" and so set that thought-processes and brain-processes ran side by side without really having anything to do with one another.[1] With the development of modern anatomy, physiology and psychology, the time is ripe for men boldly to say that applying the principle of causation in a practical manner leaves no doubt that mind and character are organic, are functions of the organism and do not exist independently of it. I emphasize "practical" in relation to causation because it would be idle for us here to enter into the philosophy of cause and effect. Such discussion is not taken seriously by the very philosophers who most earnestly enter into it.

[1] William James in Volume 1 of his "Psychology" gives an interesting resume of the theories that consider the relationship of mind (thought and consciousness) to body. He quotes the "lucky" paragraph from Tyndall, "The pa.s.sage from the physics of the brain to the corresponding facts of consciousness is unthinkable. Granted that a definite thought and a definite molecular action in the brain occur simultaneously; we do not possess the intellectual organ, or apparently any trace of the organ which would enable us to pa.s.s by a process of reasoning from one to the other." This is the "parallel" theory which postulates a hideous waste of energy in the universe and which throws out of count the same kind of reasoning by which Tyndall worked on light, heat, etc. We cannot understand the beginning and the end of motion, we cannot understand causation. Probably when Tyndall's thoughts came slowly and he was fatigued he said--"Well, a good cup of coffee will make me think faster." In conceding this practical connection between mind and body, every "spiritualist" philosopher gives away his case whenever he rests or eats.

The statement that mind is a function of the organism is not necessarily "materialistic." The body is a living thing and as such is as "spiritualistic" as life itself. Enzymes, internal secretions, nervous activities are the products of cells whose powers are indeed drawn from the ocean of life.

To prove this statement, which is a cardinal thesis of this book, I shall adduce facts of scientific and facts of common knowledge.

One might start with the statement that the death of the body brings about the abolition of mind and character, but this, of course, proves nothing, since it might well be that the body was a lever for the expression of mind and character, and with its disappearance as a functioning agent such expression was no longer possible.

It is convenient to divide our exposition into two parts, the first the dependence upon proper brain function and structure, and the second the dependence upon the proper health of other organs. For it is not true that mind and character are functions of the brain alone; they are functions of the entire organism.

The brain is simply the largest and most active of the organs upon which the mental life depends; but there are minute organs, as we shall see, upon whose activity the brain absolutely depends.

Any injury to the brain may destroy or seriously impair the mentality of the individual. This is too well known to need detailed exposition. Yet some cases of this type are fundamental in the exquisite way they prove (if anything can be proven) the dependence of mind upon bodily structure.

In some cases of fracture of the skull, a piece of bone pressing upon the brain may profoundly alter memory, mood and character.

Removal of the piece of bone restores the mind to normality. This is also true of brain tumor of certain types, for example, frontal endotheliomata, where early removal of the growth demonstrates first that a "physical" agent changes mind and character, and second that a "physical" agent, such as the knife of the surgeon, may act to reestablish mentality.

In cases of hydrocephalus (or water on the brain), where there is an abnormal secretion of cerebro-spinal fluid acting to increase the pressure on the brain, the simple expedient of withdrawing the fluid by lumbar puncture brings about normal mental life. As the fluid again collects, the mental life becomes cloudy, and the character alters (irritability, depressed mood, changed purpose, lowered will); another lumbar puncture and presto!--the individual is for a time made over more completely than conversion changes a sinner,--and more easily.

Take the case of the disease known as General Paresis, officially called Dementia Paralytica. This disease is caused by syphilis and is one of its late results. The pathological changes are widespread throughout the brain but may at the onset be confined mostly to the frontal lobes. The very first change may be--and usually is--a change in character! The man hitherto kind and gentle becomes irritable, perhaps even brutal. One whose s.e.x morals have been of the most conventional kind, a loyal husband, suddenly becomes a profligate, reckless and debauched, perhaps even perverted. The man of firm purposes and indefatigable industry may lose his grip upon the ambitions and strivings of his lifetime and become an inert slacker, to the amazement of his a.s.sociates. Many a fine character, many a splendid mind, has reached a lofty height and then crumbled before the a.s.saults of this disease upon the brain. Philosopher, poet, artist, statesman, captain of industry, handicraftsman, peasant, courtesan and housewife,--all are lowered to the same level of dementia and destroyed character by the consequences of the thickened meninges, the altered blood vessels and the injured nerve cells.

Now and then one is fortunate enough to treat with success an early case of General Paresis. And then the reversed miracle takes place, unfortunately too rarely! The disordered mind, the altered character, leaps upward to its old place,--after being dosed by the marvelous drug Salvarsan, created by the German Jewish scientist, Paul Ehrlich.

Of extraordinary interest are the rare cases of loss of personal ident.i.ty seen after brain injury, say in war. A man is knocked unconscious by a blow and upon restoration of consciousness is separated from that past in which his ego resides. He does not know his history or his name, and that continuity of the "self"

so deeply prized and held by all religions to be part of his immortality is gone. Then after a little while, a few days or weeks, the disarranged neuronic pathways reestablish themselves as usual,--and the ego comes back to the man.

One might cite the feeble-mindedness that results from meningitis, brain tumor, brain abscess, brain wounds, etc., as further evidence of the dependence of mind upon brain, of its status as a function of brain. No philosopher seriously doubts that equilibrium and movement are functions of the brain, and yet to prove this there is no evidence of any other kind than that cited to prove the relationship of mind to brain.[1] And what applies to the intelligence applies as forcibly to character, for purpose, emotion, mood, instinct and will are altered with these diseases.

[1] Except that equilibrium does not itself judge of its relationship to brain, whereas mind is the sole judge of its relationship and dependence on brain. Since everything in the world is a mental event, mentality cannot be dependent upon anything, and everything depends upon mind for its existence, or at least its recognition. But we get nowhere by such "logic" gone mad. Apply the same kind of reasoning to brain-mind, body-mind relationship which anatomists and physiologists apply to other functions, and one can no longer separate body and mind.

Interesting as is the relationship between mind and character and the brain, it is at the present overshadowed by the fascinating relationship between these psychical activities and the bodily organs. What I am about to cite from medicine and biology is part of the finest achievements of these sciences and hints at a future in which a true science of mind and character will appear.

Certain of the glands of the body are described as glands of internal secretions in that the products of their activity, their secretions, are poured into the blood stream rather than on the surface of the body or into the digestive tract. The most prominent of these glands, all of which are very small and extraordinarily active, are as follows:

The Pituitary Body (Hypophysis)--a tiny structure which is situated at the base of the brain but is not a part of that organ.

The Pineal Body (Epiphysis)--a still smaller structure, located within the brain substance, having, however, no relationship to the brain. This gland has only lately acquired a significance.

Descartes thought it the seat of the soul because it is situated in the middle of the brain.

The Thyroid gland, a somewhat larger body, situated in the front of the neck, just beneath the larynx. We shall deal with this in some detail later on.

The Parathyroids, minute organs, four in number, just behind the thyroid.

The Thymus, a gland placed just within the thorax, which reaches its maximum size at birth and then gradually recedes until at twenty it has almost disappeared.

The Adrenal glands, one on each side of the body, above and adjacent to the kidney. These glands, which are each made up of two opposing structures, stand in intimate relation to the sympathetic nervous system and secrete a substance called adrenalin.

The s.e.x organs, the ovary in the female and the t.e.s.t.i.c.l.e in the male, in addition to producing the female egg (ovum) and the male seed (sperm), respectively, produce substances of unknown character that have hugely important roles in the establishment of mind, temperament and s.e.x character.

Without going into the details of the functions of the endocrine glands, one may say that they are "the managers of the human body." Every individual, from the time he is born until the time he dies, is under the influence of these many different kinds of elements,--some of them having to do with the development of the bones and teeth, some with the development of the body and nervous system, some with the development of the mind, etc. (and character), and later on with reproduction. These glands are not independent of one another but interact in a marvelous manner so that under or overaction of any one of them upsets a balance that exists between them, and thus produces a disorder that is quite generalized in its effects. The work on this subject is a tribute to medicine and one pauses in respect and admiration before the names and labors of Brown, Sequard, Addison, Graves and Basedow, Horsley, King, Schiff, Schafer, Takamine, Marie, Cushing, Kendal, Sajous and others of equal insight and patient endeavor.
