workers, business and professional folk of all sorts, the kind of persons the world needs most—laid off for months or years of treatment, on account of some kind of nervous disorder.

Various Types of Nervousness. The psychoneuroses

are of many forms. [3] To some people "nerves" means nervous prostration, breakdown, fatigue, weakness, insomnia, the blues, upset stomach, or unsteady heart,—all signs of so-called neurasthenia or nerve-weakness. To others the word "nerves" calls up memories of strange, emotional storms that seem to rise out of nowhere, to sweep the sky clear of everything else, and to pass as they came, leaving the victim and the family equally mystified as to their meaning. These strange alterations of personality are but one manifestation of hysteria, that myriad-faced disorder which is able to mimic so successfully the symptoms of almost every known disease, from tumors and fevers to paralysis and blindness.

To still other people nervous trouble means fear,—just terrible fear without object or meaning or reason (anxiety neuroses); or a definite fear of some harmless object (phobia); or a strange, persistent, recurrent idea, quite foreign to the personality and beyond the reach of reason (obsession); or an insistent desire to perform some absurd act (compulsion); or perhaps, a deadly and pall-like depression (the blues).

As a matter of fact, the neuroses include all these varieties, and various shades and combinations of each. There are, however, certain mental characteristics which recur with surprising regularity in most of the various phases—dissatisfaction, lack of confidence, a sense of being alone and shut in to oneself, doubt, anxiety, fear, worry, self-depreciation, lack of interest in outside affairs, pessimism, fixed belief in one's powerlessness, along whatever line it may be.

Underneath all these differing forms of nervousness are the same mechanisms and the same kind of difficulty. To understand one is to understand all, and to understand normal people as well; for in the last analysis we are one and all built on the same lines and governed by the same laws. The only difference is, that, as Jung says, "the nervous person falls ill of the conflicts with which the well person battles successfully."

Summary

Since at least seventy-five per cent. of all the people who apply to physicians for help are nervous patients; and since these thousands of patients are not among the mental incompetents, but are as a rule among the highly organized, conscientious folk who have most to contribute to the leadership of the world, it is obviously of vital importance to society that its citizens should be taught how to solve their inner conflicts and

keep well. In this strategic period of reconstruction, the world that is being remodeled cannot afford to lose one leader because of an unnecessary breakdown.

There is greater need than ever for people who can keep at their tasks without long enforced rests; people who can think deeply and continuously without brain-fag; people who can concentrate all their powers on the work in hand without wasting time or energy on unnecessary aches and pains; people whose bodies are kept up to the top notch of vitality by well-digested food, well-slept sleep, well-forgotten fatigue, and well-used reserve energy. That such a state of affairs is no Utopian dream, but is merely a matter of knowing how, will appear more clearly in later chapters.

CHAPTER II

In which we learn what "nerves" are not, and get a hint of what they are

THE DRAMA OF NERVES

An Exploded Theory

"Nerves" not Nerves. Pick up any newspaper, turn over a few pages, and you will be sure to come to an advertisement something like this:

No wonder people have believed this kind of thing. It has been dinned into their ears for many years. They have read it with their breakfast coffee and gazed at it in the street cars and even heard it from their family physicians, until it has become part and parcel of their thinking; yet all the time the fundamental idea has been false, and now, at last, the theory is exploded.

So far as the modern laboratory can discover, the

nerves of the most confirmed neurotic are perfectly healthy. They are not starved, nor depleted, nor exhausted; the fat-sheath is not wanting, there is no inflammation, there is nothing lacking in the cell itself, and there is no accumulation of fatigue products. Paradoxical as it may sound, there is nothing the matter with a nervous person's nerves. The faithful messengers have borne the blame for so long that their name has gotten itself woven into the very language as symbolic of disease. When we speak of nervous prostration, neurasthenia, neuroses, nervousness, and "nerves" we mean that body and mind are behaving badly because of functional disorder. These terms are good enough as figures of speech, so long as we are not fooled by them; but accepting them in their literal sense has been a costly procedure.

Thanks to the investigations of physiologist and psychologist, usually combined in the person of a physician, "nervousness" has been found to be not an organic disease but a functional one. This is a very important distinction, for an organic disease implies impairment of the tissues of the organ, while a functional disorder means only a disturbance of its action. In a purely nervous disorder there seems to be no trouble with what the nerves and organs are, but only with what they do; it is behavior and not tissue that is at fault. Of course, in real life, things are seldom as

clear-cut as they are in books, and so it happens that often there is a combination of organic and functional disease that is puzzling even to a skilled diagnostician. The first essential is a diagnosis as to whether it be an organic disease, with accompanying nervous symptoms, or a functional disturbance complicated by some minor organic trouble. If the main cause is organic, only physical means can cure it, but if the trouble is functional, no amount of medicine or surgery, diet or rest, will touch it; yet the symptoms are so similar and the dividing line is so elusive, that great skill is sometimes required to determine whether a given symptom points to a disturbance of physical tissue or only to behavior.

If the physician is sometimes fooled, how much more the sufferer himself! Nausea from a healthy stomach is just as sickening as nausea from a diseased one. A fainting-spell is equally uncomfortable, whether it come from an impaired heart or simply from one that is behaving badly for the moment. It must be remembered that in functional nervousness the trouble is very real. The organs are really "acting up." Sometimes
