Insanity Part 10

The truth is, that religious ideas and beliefs are innate in man. We find them in some form or other among all tribes and races, from the lowest South Sea Islander up to the representative types of the race; all alike realize, imperfectly it may be, and yet distinctly, that they are both feeble and ignorant, in the midst of the infinite variety and extent of the universe about them, and they instinctively look, in their feebleness, toward a Power above and superior to them, as naturally as the child looks to the parent for support and protection.

There is a law operative among all creatures, that every instinct of the being has something answering to it from without, toward which it turns in its periods of need and helplessness. The breast of the mother answers to the instinctive action of the hungry infant; the strength of parents to the feeble clinging of the child; the atmosphere to the outstretched moving wing of the bird; the water to the waving fin of the newly hatched fish; and these instincts would not exist except for the answering reality outside and about them, which calls them into activity.

So it must ever be, as to religious belief in the human race. Man realizes at times, and will always continue to do so, that he is a very helpless being in the midst of a stupendous system, a relentless on-going of nature, silent as the tomb and terrible as fate, and from which there come to him no voices of a.s.surance and no gleams of hope. It cannot otherwise be, than that he should feel, even in the fulness of his strength and the highest realization of his powers, that he stands as on a grain of sand only; that the longest ranges of his vision are soon enveloped in darkness; that his knowledge is as ignorance when compared with that wisdom which is manifested by the greatness of worlds which look down upon him from the depths of s.p.a.ce. He must always realize how feeble are his highest conceptions or imaginations, when he tries to push them out among the systems of worlds which are so much larger and grander than his own, or when he undertakes to change or regulate a movement or operation of nature.

This being so, it must be that man will, in the future as in the past, look toward and seek help from some Power above and beyond himself. The instinct is and must be as true to the reality as is that of the hungry child when it turns to its mother, or that of the fish which leads it to move when in the water; and, as the water answers to the instinct of the fish, as the breast of the mother to the calling of the child, and the atmosphere to the wing of the bird, so, too, must there exist a Being responsive to that instinct which leads man to pray and trust.

That this quality or faculty of his nature has been unwisely used, that it has been greatly abused; that it has been mis-educated, and often mis-directed, and too often turned into an instrument for inflicting suffering and ill, history, alas! makes only too clear; but so have other faculties of man's mind, and so will they continue to be, except they are trained and educated toward higher and better purposes; and the problem in reference to religious belief is, not how to ignore or blot it out, or ridicule it as a monument of superst.i.tious belief, or explain it away, but rather how to so educate and strengthen it, that it shall conduce toward endurance and stability of the brain, and thus render it better able to bear up under the strain, labors, and hara.s.sing disappointments of life. It appears to me that religious belief may be made one of the most potent of agencies in this direction, and the following suggestions would seem to strengthen this view.

First, the laws of health and those of religion go hand in hand; the two fundamentally agree. There exists a broad basis in the very nature of man's system, on which to build up religious belief and practice.

Temperance, honesty, obedience to parents, truthfulness, chast.i.ty, recognition of sacred times, and brotherly kindness are no less in accordance with the laws of bodily and mental health, than they are with the laws and ordinances of the Christian religion, and when man sins against one he does also against the other. The two are in harmony with the const.i.tution of his system, and their observance can conduce only toward his highest health and consequent happiness. On the other hand, a failure in their observance, or intemperance, licentiousness, and dishonesty, no less surely war against the nature of his mental const.i.tution, and tend toward ill-health.

Again, a religious belief and practice conduce largely toward sustaining the mind in the experience of suffering and misfortune, and thus are indirectly of very essential service toward securing and preserving integrity of mental action.

Account for the fact as we may, the conditions of society are sadly out of gear. The vast majority of the human race now are, always have been, and are always likely to be, in a condition largely of dependence. The most sanguine optimist must admit that long ages will pa.s.s, ere that time shall come when the superior in physical and mental ability shall not use that superiority for his own advantage, as against that of his less-favored brother. In the later phases of civilization, this has pa.s.sed somewhat from the manifestation of muscular force, but it has only gone over into that of mental force. Brain now rules where formerly muscle did; and the man of superior brain, to-day, under the forms and protection of law, and by virtue of his intelligence, rules over others, and secures his purposes, as surely as formerly the man of greater physical strength did.

So long as such conditions continue, so long will ignorance, disease, and misery exist, and consequently there will exist in the human system needs of the consolation and hope which can come to man only from the teachings of religion. And he will not only require the teachings of religion by which to be guided and its admonitions to influence, but also such hopes and antic.i.p.ations as it alone can offer as to a higher and better condition of existence hereafter. The expectation that, some time in the ages of the world, some of those who are to come after him may possibly be in a more favored condition of existence on earth, will afford too little comfort to him in his ofttimes-condition of suffering and ignorance. If the present is to end all, and there may be no to-morrow for him in which he may hope for some adjustment and antic.i.p.ate a higher plane of existence, then the darkness and mystery of life itself become profoundly inexplicable. But the expectation of a condition of existence hereafter, wherein he shall be released from the companions of disease and want, which now so often haunt his every year of life, will stimulate hope, and consequently tend toward health of mind.

Again, man requires that which religion alone can bring to him to satisfy the aspirations of his higher nature. The press and throng of daily life, in its many-sided avocations, satisfy only as to material things and for a brief present. Science, in its numerous phases and advancing strides, has done something, and there can be no doubt will in the future do still more, for man's happiness and material gain; but these are not all, nor sufficient for his greatest needs. They deal only with things observable and physical.

Science unfolds some of the mysterious processes which are constantly going on in man's system; it demonstrates or photographs for the eye the approximate structure of nerve-cells or globules of blood; it has traced out some of the mysterious mechanism of cerebration, and delineated with more or less exact.i.tude some of the great chemical activities which are forever going on in organic bodies. It has gone farther, and revealed some of the hitherto wonderful mysteries in the earth and in the worlds above.

But, after all, its sphere is circ.u.mscribed, and mystery still surrounds us with an impa.s.sable wall. The greatest and wisest of its votaries have at last to confess with confusion of face that they have arrived only on the brink of an ocean which is infinite--that they know but little.

Science is good and its study enn.o.bling, but it does not suffice for man's highest aspirations, nor for the development of his moral nature. It has never explained the mystery of a single act of his will, and can never ascend into the region of the spiritual. Man may press onward and upward in its paths never so far, and there still remains the infinite beyond.

His imaginations may invade the furthest circle of planetary motion, and yet we know there remain system after system of worlds, and suns s.h.i.+ning with ineffable light, still beyond. His questions are never answered; his longings are never satisfied, and never can be until they reach The Infinite One--the object of his wors.h.i.+p,--the Source of light and all knowledge.

His questions have ever been, whence am I? and whither do I go? and it can never satisfy his aspirations, to reply that he is from the ape, and goes to the ground, and that this ends all. There still remains to him a longing for immortality; a craving for something above and beyond what he now sees and knows, and only in the hope of this something hereafter, does he have a realization of his highest possibilities.

I believe that thus far in man's experience he has been the loser, not by too much religion, but rather by his unbelief and misconceptions as to its true nature and the extent of its obligations. The plan should therefore be, for a broader, higher, and more pervading religious influence, which can come only from an intelligence educated as to his relations toward and responsibility to G.o.d, and his fellow-men. As the tendency of the laws of health and religion are in the same direction, it is not easy to understand how a religious belief, or the influences which legitimately flow from it, can be otherwise than for the highest interests of society, and the mental health of its individual members.

CHAPTER XV.

INSUFFICIENT SLEEP.

We learn the most important lessons from observing the facts and studying the operations of nature, and it is largely by such a course that we may hope to learn the true method of either understanding or practising such courses in life as will conduce to health.

From the time of birth until the body finally rests in its last sleep, the human system requires periods of repose under the conditions of sleep. The child, during the first few months of its existence, pa.s.ses the larger portion of the time in this state. While in it, the brain and nervous system develop more rapidly, grow in stability, and attain capacity for activity more surely than is possible in any other.

It is true that we do not yet understand precisely in what the phenomenon of sleep consists; we do not know fully what change in the operation of the brain occurs for its induction. It may be from deviated or lessened currents of blood in certain portions, or from the opposite condition.

Both these theories have been advocated by men more or less eminent as physiologists; some maintaining that while in sleep the brain contains a larger amount of blood, that there exists a diminished action of the vaso-motor nerves which control the coats of the vessels of the brain, and that in consequence they become more fully distended than when the brain is in a conscious state of activity.

On the other hand, others become equally positive, from observations made on portions of the brain which have become exposed through the effects of injuries to the skull, that these vessels contain less blood during sleep than when in other conditions. I think these observations are conclusive, and that there can be no doubt as to the fact that there exists a diminished quant.i.ty of blood in the vessels of the brain in sleep; but that this is the cause of the occurrence of that condition of the brain which const.i.tutes sleep does not appear to be so certain. It is quite possible that this diminished quant.i.ty of blood is rather a _consequence_ than a _cause_. I am more inclined to think that sleep is primarily caused by a diminution, or cessation, of some of the electrical currents which constantly are pa.s.sing through portions of the brain while in a state of consciousness, and which are probably necessary to a condition of consciousness, and that the anaemic condition of the brain which is observed during sleep is a result of such change in these currents.

But from whatever primary cause it may occur, we know that it is only when there are frequent periods for this condition of the brain in the case of the child, that its nervous system develops and becomes strong in the largest measure. And on the other hand, when, for any cause, whether it be pain or artificial excitement, sleep is prevented, the whole system speedily becomes deranged, and manifests its sense of indignation by irregular or imperfect development and suffering.

The necessity of sleep for the system might be ill.u.s.trated by the presentation of many remarkable and curious facts, such as those of persons who are greatly exhausted sleeping during surgical operations; of physicians sleeping while walking to or from visits to their patients, or while sitting beside them when in conditions of great suffering. I have myself, when greatly fatigued from excessive professional labor, slept through a considerable portion of a disagreeable and somewhat painful dental operation. The torture resulting from the deprivation of sleep for long periods is said to be greater than that of hunger or thirst, or from the infliction of the severest bodily injury.

Accounts received from persons who have been s.h.i.+pwrecked, or exposed in open boats upon the water in situations of great personal danger, and where, in consequence, no sleep could be indulged, go to confirm this view; and, though these accounts may have been somewhat exaggerated, and reporters have drawn somewhat upon their imagination in their efforts to depict these experiences, yet those who have been long deprived of sleep, and have been obliged to struggle against its mastery day after day, may easily imagine how terrible must be the suffering under such circ.u.mstances. And yet, how little this imperative demand of nature and the importance of this great necessity of the brain have been understood, especially in reference to children.

When a young man and a student, I well remember hearing some lectures from a person calling himself a physician, in which he took the ground that fifteen minutes was ample time in which to take a regular meal, and that all time spent in sleep in excess of four or five hours at most, was so much lost time; that if persons slept only five hours instead of eight, they would gain more than six years of time in the course of fifty; therefore, every person who was so much of a sluggard as to sleep eight hours instead of five, was responsible for wasting six years in fifty.

That ambitious insect, the ant, was held up by the doctor as an example of industry and lofty enterprise, worthy the imitation of everybody who expects to do much in life--as if he knew how many hours that creature is in the habit of sleeping every year.

He might almost as well have put his case stronger, and argued that it was everybody's duty to sleep only two of the twenty-four hours, because, forsooth, we would gain more than twelve years in the fifty by so doing.

Unfortunately for society, this man has not been alone in advocating such views. There have been others who, in their teachings, have greatly underestimated the importance of an abundance of sleep as a means of securing and maintaining a high standard of health. I think that most persons, especially of the laboring cla.s.ses, in cities as also in the country, sleep too little. This is true as to adult persons, but to a much larger extent of children, and it is hardly possible to over-estimate the good effects arising from an abundance of sleep upon the brain of the child.

There are certain physiological and anatomical conditions existing which tend to show why this is true.

1. The brain at an early age attains a size out of proportion to other organs and members of the body. This is especially true of that portion of the brain supposed to be concerned in mental operations, while those portions whose office is connected with the organic life of the system are less advanced. After twelve or fourteen years of age, the relative rapidity of development as to size becomes changed, and other portions of the system increase more rapidly.

2. The cells of the hemispheres of the brain contain a considerably larger amount of water during the younger periods of life than they do during the adult period. One of the results of this condition of the brain is that of less stability of character, and a larger measure of susceptibility. It is more sensitive and easily disturbed by external surroundings, while the influences which act upon it, in connection with its daily experiences, tend to create a much more rapid metamorphosis of its tissues.

The nerve tissue of the brain in adult life is the most unstable in its elemental composition of that of any organ, but in childhood and youth the change resulting in degeneration and restoration of tissue is much more rapid than at any other period. Hence the importance of frequent and considerably long-continued periods of sleep and inactivity of this organ.

Now, my observation and experience lead me to believe that young children in our cities sleep far too little to enable the brain to receive the largest benefit from it; that they are out on the streets, or employed at tasks, long after they should have been in bed. In many portions of our large cities there exist excitement and noise, which are quite sufficient to prevent sleep, until the system is very greatly fatigued, and the nervous elements exhausted. Parents are frequently thoughtless and careless in this respect, and the children are left out on the street or visiting at neighbors' houses until too late an hour.

A teacher in a public school informs me that one of the greatest hindrances in the advancement of some of her scholars, lies in the fact that one or two nights of every week these children are out at musical or dancing parties, or attending some place of public amus.e.m.e.nt, so that the period of sleep is greatly abridged, and the brain has not recuperated its energy so as to be able to study. The sensitive tissue is in a condition of too great weakness to be much used, and in consequence the difficulty of learning lessons is greatly increased.

Again, children are often called in the morning, long before enough sleep has been secured to refresh the brain, and employed in different ways, perhaps in attending to some piece of machinery in a large factory, which is filled with dust and the noise of thousands of wheels, and kept there ten or twelve hours a day; and the brain is not allowed to sleep for sixteen or seventeen hours.

Now, one of the effects of these long periods of wakefulness and over-activity is to check the normal development of the brain, to stint its growth, and give it a twist from which it never recovers. This habit, formed in childhood, frequently extends into adult life, and becomes so fixed that it is difficult for the brain afterward to change its custom.

The period of wakefulness tends to increase so that sleep is limited to six or seven instead of eight or nine hours.

That man who regularly and soundly sleeps his eight or nine hours a day should be the man capable of large physical or mental work; moreover, he is the man who lasts longest; his system becomes daily recuperated, and he has the largest prospect of reaching his threescore and ten, while yet his system is in a degree of health; while his neighbor, less favored in this respect, becomes old at sixty if he chances to live so long.

It is not intended to imply that there may not be exceptions to this rule.

There have been some who could do with four or five hours' sleep for many years and do good work, and there are probably such men to-day, but they are using up the nervous energy and strength with which they have been endowed far too rapidly; and they are exceptions to the ma.s.s of people, who require much more sleep in order to enjoy good mental health.

Sleep is to the brain what rest is to the body:

"Sleep, that knits up the ravelled sleeve of care, The death of each day's life, sore labor's bath, Balm of hurt minds, great Nature's second course, Chief nourisher in life's feast."

No words could paint more beautifully or effectively the office of sleep, than these of England's greatest poet. But we need not turn to the writers of prose or poetry in the past for instruction in this matter; all nature teaches the importance of sleep. Every tree, and shrub, and vine, has its period of sleep, and, if stimulated into ceaseless activity, would soon die; and every portion of the human system is subject to the same great law of necessity.

The stomach must have its periods of inactivity and rest; and there are periods during every twenty-four hours when the kidneys secrete very little, if any, urine. It is sometimes said the heart is an exception to this rule; that its beat never ceases from more than six months before birth until nature's last great debt is paid in death. But, in truth, it is at entire rest nearly if not quite one third of the whole time. Its action consists of a _first_ and a _second_ sound, covering the contraction of right and left auricles and ventricles, and then a rest,--and so far as we know a perfect one. Reckoning this at one third the time occupied in each full action of the heart, and we have more than twenty years of perfect quiet out of the threescore and ten.

The same is true to even a larger extent of other involuntary processes and movements; for instance, that of respiration. The muscles concerned in this operation are at entire rest during more than one third of the time, and if the process of respiration be much quickened in frequency for any considerable period of time, weariness and languor ensue.

Now the brain is no exception to this same law. During every moment of consciousness this is in ceaseless activity. The peculiar process of cerebration, whatever that may consist in, is taking place; thought after thought comes forth, with no volition on our part; long trains of meditation come forth unbidden, one after another, from the hidden recesses of the brain; sometimes things supposed to be long since forgotten, which have for years been consigned to the rubbish lumber-heap of dead plans and disappointed expectations, rise up suddenly, like a frightened bird before the hunter. Then, again, the sound of some voice, or the strain of some music long unheard, or the glance of an eye, will call up the memories of some bitter and suffering experience with its ten thousand harrowing a.s.sociations, which go marching forward and backward through the trackless channels of the brain like a vast army of ghosts.

All this when the brain has no set task to perform, no intent purpose to follow out, and the body is at ease; and it is only when the peculiar connection or chain of connection of one brain-cell with another is broken, and consciousness fades away into the dreamless land of perfect sleep, that the brain is at rest. In this state it recuperates its exhausted energy and power, and stores them up for future need.

The period of wakefulness is one of constant wear; every thought is generated at the expense of brain-cells, which can be fully re-energized only by periods of properly regulated repose. It not unfrequently happens, however, that sleep is only partial; that the brain still continues in some degree of activity, and when we wake, we have dim memories of sub-conscious thought, which has been moving through the brain. Such rest, for the brain, is imperfect, and we are conscious of the conditions of fatigue, which shows how imperative is the necessity for sound, healthy sleep; and if this is not secured, if the brain, through over-stimulation and thought, is not left to recuperate, its energy becomes rapidly exhausted; debility, disease, and finally, loss of power supervene.
