INSANITY AND CIVILIZATION.

Information in reference to the character of the diseases which formerly existed among the aborigines of North America, or among uncivilized peoples of other countries, in the past, is both meagre and indefinite. Legends concerning widespread epidemics of some forms of disease, especially the yellow fever and small-pox, among those tribes which formerly lived on the territory which now constitutes New England, have been handed down, and there must have occurred cases of insanity, to a greater or less extent, among all savage nations, arising from injuries to some portion of the nervous system; but, for the most part, those conditions and experiences of life which appear to predispose or excite the nervous system into diseased action, were probably absent.

Those who were born with weakened or defective organizations, either physical or mental, would, under the exposed conditions and the rude experiences of uncivilized life, hardly attain to adult age, even if they were not intentionally left to perish, so that the vast majority of those who did arrive at those periods of life during which insanity generally manifests itself, would probably possess such nervous organizations as would be little liable to become insane.

Their modes of living, also, being for the most part in the open air, and without excessive labor or exertion, except on occasions, and during short periods; and living in comparative freedom concerning those uncertainties of business and property which exist so generally among some classes, and even nations, under the conditions of civilized life; having few needs, and those of such a nature as to be easily supplied, would all be unfavorable to the development of insanity.

Again, uncivilized persons have but little sensitiveness, and are easily satisfied in reference to that long range of sentiment and feeling which holds so large a sway, and wields so strong an influence, in the lives of their brethern and sisters in civilized life; and, moreover, experience few of the annoyances, disappointments, and vexations which result from the habits and customs of our forms of domestic and business conditions.

Yet it appears to be a humiliating admission to make, that, with all the increase of mental power and range of thought, with acquired power over the forces of nature, with ability to convert the hidden treasures and forces of nature, into the means of supplying wants and ministering to comfort, and, with the vast storehouse of mental wealth which comes into the possession of mankind through the influences of civilization, there should, somehow, necessarily come with them, greater liability to such a calamity as insanity. This is, however, but one of many evils which invariably come into existence under the changed relations and circumstances of life, not only while passing from the habits of uncivilized life to those of a high state of civilization, but especially while living in the latter condition.

It is exceedingly difficult to differentiate, and accurately state in few words, what is signified by either insanity or civilization. Both are terms, the general signification of which, for practical purposes, is supposed to be well enough understood, but when we are called upon to give a clear and at the same time a fully comprehensive definition of them, there is much difficulty in doing it.

As has been very clearly shown by Dr. Arthur Mitchell,[2] civilizations may differ in different countries, as well as at different periods of time in the same country; they may be old or new, high or low, one thing in this century, and another in the next. That of the ancient Greek certainly differed widely from that of the Roman, while both differed largely from the European civilization of the present time.

In one view of the subject, that which regards it as something separate and distinct from those unfavorable conditions which always accompany its progress, we may say that civilization may be considered as the measure of perfection reached by society as a whole, toward living in harmony with its environments, in a civil condition.

But, inasmuch as no civilization has yet appeared among any people, so far as we know, or is soon likely to appear, free from those imperfections which affect even large numbers, some other more practical idea of its character will be necessary. For my present purpose it may be considered as the sum of results, which follow from the total of activities in operation among any people, while living under those conditions which always have pertained to civil life.

These results will vary even largely from one period of time to another, and will be partly good and partly bad. Indeed, I think it will be found that, in the degree in which nations have passed from those conditions which pertain to life in the savage state, upward toward those which abound in civilized life, in that measure has the sum total of diseased conditions, in both body and mind, increased; in this measure have there resulted degenerations of nerve element, and consequent failure to attain to and live in harmony with those artificial arrangements and conditions with which society in the civil state has, thus far in its history, uniformly surrounded itself.

In other words, while man has largely gained in some directions; while his mind has become more active and far-reaching in its range of thought, and many-sided in its activities; while the comforts and luxuries of life have become many times larger, by abandoning those conditions of life which pertain to the savage state, and assuming others of a vastly higher and more complex nature, yet, thus far in his history, he has not succeeded in surrounding society by such regulations, and in securing obedience to such laws, as will suffice to preserve and retain the health and strength of body which existed while in the savage state, except among the few.

That many of the conditions pertaining to modern civilization prove to be highly conducive to physical diseases, needs hardly to be said, and that they are no less productive of insanity and other diseases of the nervous system, will be evident from some considerations to be alluded to in connection with this discussion.

1. At first thought it might appear that the development and extension of civilization, which carries with it so many and great advantages in many other respects, should also be favorable to mental health. It is a law of the human system that the various organs become strong and maintain a high standard of health, only while under a considerable degree of activity, and this is especially true of the muscular and nervous systems. Inactivity and disuse tend toward degeneration, therefore, such circumstances and surroundings of life as will conduce to harmonious activity of these organs and parts, would, ceteris paribus, be most favorable to health.

Now the various portions and faculties of the human brain are brought into a state of full development and activity only under the conditions and influences of civilization; all of those higher and finer manifestations of thought, sentiment, and feeling, which pertain only to man; the satisfaction which comes from the results of mental activities both in relation to mechanics, education, governments, and the social amenities; the increase of strength pertaining to thought, and consequent self-reliance, and ability to rise above the adverse circumstances and experiences of life; freedom from the conditions of uncertain and limited supply, with attainment of those of a fairly certain and abundant character; the results which come from travel, and intercourse with persons of other nationalities; from trade, commerce, and intellectual pursuits; together with the possession of knowledge, which is power—all come only from the conditions and influences of civilization, and should rather have a tendency to confirm and make strong mental health.

And this would undoubtedly be the result, if these were all, or indeed mainly, the effects attendant on living under the influences of civilization.

But, unfortunately, these are only some of the beneficent results of this change. Other influences, customs, and practices, and those of a character highly adverse to the maintenance of healthy mentality, have also come into operation, to a greater or less extent, and are especially potent in modern civilization.

With the increase of mental activity alluded to, there have come into a fuller range of activity those portions of the brain which are concerned with thought, and which, in the narrow limits and simple conditions before experienced, had been comparatively inactive. Consequently, a larger supply of blood has been summoned to these parts of the brain to repair the loss incurred by this increased activity. This change and consequent disturbance in the relative blood-supply, as between the brain and other parts of the system, would be of little importance if sufficient care be exercised that it comes in the right degree, and does not cause too great activity in the organ of the mind; indeed, there might be expected favorable results from a larger exercise of function, or at least not unfavorable ones.

In the experience of modern times, however, this has not proved to be the case. With the measure of mental power and scope which attends the change, there has been a large tendency to over-stimulate the intellectual faculties, which has been aided and thought to be necessary, in consequence of the immense competitions and business activities of modern civilization.

This tendency to stimulation has been manifest even to a much larger extent than formerly, first, in the matter of education. The new conditions and employments of life, rendered prominent by some of the discoveries which pertain to science, agriculture, commerce, and the general conduct of business pursuits, have developed requirements on the part of those who are called upon to conduct them, which have been heretofore unknown. To meet these requirements it has been thought necessary to pursue such courses of education, and to present such special incentives to study on the part of the young, by the use of prizes and grades of scholarship, and public exhibitions, as will bring into operation the largest possible activity, and secure the highest discipline of the brain, even at a very early period of life. At this time all the forces of vitality and physical growth are in the fullest activity, so that the strain comes upon the brain at the period when it has the least of ability to bear it, and at expense to other portions of the system.

And again, in the use of stimulants, especially alcohol, in some of its forms, and tobacco, during the period of growth and early manhood. The use of these substances, as well as the subject of education, in their effects upon the nervous system, will be discussed more fully in future chapters, and are only mentioned, in this connection, as causes of nerve degeneration, which have come into operation more fully through the influence of modern civilization.
