The Foundations of Personality [24]
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
