In 1840 there were in Europe 3,000 kilometres of railway; in 1891 there were 218,000 kilometres. The number of travellers in 1840, in Germany, France and England, amounted to 2-1/2 millions; in 1891 it was 614 millions. In Germany every inhabitant received, in 1840, 85 letters; in 1888, 200 letters. In 1840 the post distributed in France 94 millions of letters; in England, 277 millions; in 1881, 595 and 1,299 millions respectively. The collective postal intercourse between all countries, without including the internal postage of each separate country, amounted, in 1840, to 92 millions; in 1889, to 2,759 millions. In Germany, in 1840, 305 newspapers were published; in 1891, 6,800; in France, 776 and 5,182; in England (1846), 551 and 2,255. The German book trade produced, in 1840, 1,100 new works; in 1891, 18,700. The exports and imports of the world had, in 1840, a value of 28, in 1889 of 74, milliards of marks. The ships which, in 1840, entered all the ports of Great Britain contained 9-1/2, in 1890 74-1/2, millions of tons. The whole British merchant navy measured, in 1840, 3,200,000; in 1890, 9,688,000 tons.

Let us now consider how these formidable figures arise. The 18,000 new publications, the 6,800 newspapers in Germany, desire to be read, although many of them desire in vain; the 2,759 millions of letters must be written; the larger commercial transactions, the numerous journeys, the increased marine intercourse, imply a correspondingly greater activity in individuals. The humblest village inhabitant has to-day a wider geographical horizon, more numerous and complex intellectual interests, than the prime minister of a petty, or even a second-rate state a century ago. If he do but read his paper, let it be the most innocent provincial rag, he takes part, certainly not by active interference and influence, but by a continuous and receptive curiosity, in the thousand events which take place in all parts of the globe, and he interests himself simultaneously in the issue of a revolution in Chili, in a bush-war in East Africa, a massacre in North China, a famine in Russia, a street-row in Spain, and an international exhibition in North America. A cook receives and sends more letters than a university professor did formerly, and a petty tradesman travels more and sees more countries and people than did the reigning prince of other times.

All these activities, however, even the simplest, involve an effort of the nervous system and a wearing of tissue. Every line we read or write, every human face we see, every conversation we carry on, every scene we perceive through the window of the flying express, sets in activity our sensory nerves and our brain centres. Even the little shocks of railway travelling, not perceived by consciousness, the perpetual noises, and the various sights in the streets of a large town, our suspense pending the sequel of progressing events, the constant expectation of the newspaper, of the postman, of visitors, cost our brains wear and tear. In the last fifty years the population of Europe has not doubled, whereas the sum of its labours has increased tenfold, in part even fifty-fold. Every civilized man furnishes, at the present time, from five to twenty-five times as much work as was demanded of him half a century ago.

This enormous increase in organic expenditure has not, and cannot have, a corresponding increase of supply. Europeans now eat a little more and a little better than they did fifty years ago, but by no means in proportion to the increase of effort which to-day is required of them. And even if they had the choicest food in the greatest abundance, it would do nothing towards helping them, for they would be incapable of digesting it. Our stomachs cannot keep pace with the brain and nervous system. The latter demand very much more than the former are able to perform. And so there follows what always happens if great expenses are met by small incomes; first the savings are consumed, then comes bankruptcy.

Its own new discoveries and progress have taken civilized humanity by surprise. It has had no time to adapt itself to its changed conditions of life. We know that our organs acquire by exercise an ever greater functional capacity, that they develop by their own activity, and can respond to nearly every demand made upon them; but only under one condition—that this occurs gradually, that time be allowed them. If they are obliged to fulfil, without transition, a multiple of their usual task, they soon give out entirely. No time was left to our fathers. Between one day and the next, as it were, without preparation, with murderous suddenness, they were obliged to change the comfortable creeping gait of their former existence for the stormy stride of modern life, and their heart and lungs could not bear it. The strongest could keep up, no doubt, and even now, at the most rapid pace, no longer lose their breath, but the less vigorous soon fell out right and left, and fill to-day the ditches on the road of progress.

To speak without metaphor, statistics indicate in what measure the sum of work of civilized humanity has increased during the half-century. It had not quite grown to this increased effort. It grew fatigued and exhausted, and this fatigue and exhaustion showed themselves in the first generation, under the form of acquired hysteria; in the second, as hereditary hysteria.

The new æsthetic schools and their success are a form of this general hysteria; but they are far from being the only one. The malady of the period shows itself in yet many other phenomena which can be measured and counted, and thus are susceptible of being scientifically established. And these positive and unambiguous symptoms of exhaustion are well adapted to enlighten the ignorant, who might believe at first sight that the specialist acts arbitrarily in tracing back fashionable tendencies in art and literature to states of fatigue in civilized humanity.

It has become a commonplace to speak of the constant increase of crime, madness and suicide. In 1840, in Prussia, out of 100,000 persons of criminally responsible age, there were 714 convictions; in 1888, 1,102 (from a letter communicated by the Prussian bureau of statistics). In 1865, in every 10,000 Europeans there were 63 suicides; in 1883, 109; and since that time the number has increased considerably. In the last twenty years a number of new nervous diseases have been discovered and named.[61] Let it not be believed that they always existed, and were merely overlooked. If they had been met with anywhere they would have been detected, for even if the theories which prevailed in medicine at various periods were erroneous, there have always been perspicacious and attentive physicians who knew how to observe. If, then, the new nervous diseases were not noticed, it is because they did not formerly appear. And they are exclusively a consequence of the present conditions of civilized life. Many affections of the nervous system already bear a name which implies that they are a direct consequence of certain influences of modern civilization. The terms ‘railway-spine’ and ‘railway-brain,’ which the English and American pathologists have given to certain states of these organs, show that they recognise them as due partly to the effects of railway accidents, partly to the constant vibrations undergone in railway travelling. Again, the great increase in the consumption of narcotics and stimulants, which has been shown in the figures above, has its origin unquestionably in the exhausted systems with which the age abounds. There is here a disastrous, vicious circle of reciprocal effects. The drinker (and apparently the smoker also) begets enfeebled children, hereditarily fatigued or degenerated, and these drink and smoke in their turn, because they are fatigued. These crave for a stimulus, for a momentary, artificial invigoration, or an alleviation of their painful excitability, and then, when they recognise that this increases, in the long-run, their exhaustion as well as their excitability, they cannot, through weakness of will, resist those habits.[62]

Many observers assert that the present generation ages much more rapidly than the preceding one. Sir James Crichton-Browne points out this effect of modern circumstances on contemporaries in his speech at the opening of the winter term, 1891, before the medical faculty of the Victoria University.[63] From 1859 to 1863 there died in England, of heart-disease, 92,181 persons; from 1884 to 1888, 224,102. Nervous complaints carried off from 1864 to 1868, 196,000 persons; from 1884 to 1888, 260,558. The difference of figures would have been still more striking if Sir James had chosen a more remote period for comparison with the present, for in 1865 the high pressure under which the English worked was already nearly as great as in 1885. The dead carried off by heart and nerve diseases are the victims of civilization. The heart and nervous system first break down under the overstrain. Sir James in his speech says further on: ‘Men and women grow old before their time. Old age encroaches upon the period of vigorous manhood.... Deaths due exclusively to old age are found reported now between the ages of forty-five and fifty-five....’ Mr. Critchett (an eminent oculist) says: ‘My own experience, which extends now over a quarter of a century, leads me to believe that men and women, in the present day, seek the aid of spectacles at a less advanced period of life than their ancestors.... Previously men had recourse to spectacles at the age of fifty. The average age is now forty-five years.’ Dentists assert that teeth decay and fall out at an earlier age than formerly. Dr. Lieving attests the same respecting the hair, and assures us that precocious baldness is to be specially observed ‘among persons of nervous temperaments and active mind, but of weak general health.’ Everyone who looks round the circle of his friends and acquaintances will remark that the hair begins to turn gray much sooner than in former days. Most men and women show their first white hairs at the beginning of the thirties, many of them at a very much younger age. Formerly white hair was the accompaniment of the fiftieth year.
