6. The Average Man Grows Older and Wiser
The numbers and the quality of the human population have changed very greatly in the past two centuries. Always these things have varied; every animal and vegetable species fluctuates continually in the numbers and quality of its individuals; but it is only recently that these movements have been recorded and examined systematically. The anti-progressives of the early twentieth century loved to assert that “human nature” never altered; to imagine that the men of the Stone Age felt and thought like bank clerks picnicking in a cave, and that the ideas of Confucius and Buddha were easily interchangeable with the ideas of Rousseau, Karl Marx or De Windt. They were not simply ignorant but misinformed about almost every essential fact in the past experiences and present situation of the race. Only when the twenty-first century was well under way did any consciousness of the primary operating forces in human biology appear in the discussion and conduct of world affairs.
In the year 1800 the total population of the world was under 900 millions, and the average age was about 22. In 1900 the population had doubled and the average age had risen by nearly ten years. In 1935 a maximum was attained of 2000 millions and the average age had mounted to nearly 40. In a hundred years the facilities for intercommunication and physical reaction had increased beyond all measure. But the statesmen, educators and lawyers of that age, as we have shown very plainly in this history, were unaware of any of these differences that had occurred since their methods were developed. They drooled along according to precedent. A set-back for adjustment was therefore inevitable. We have told the broad facts of the crash that began with the war massacres of 1914-18 and culminated in the cycle of pestilences before 1957. In thirty years the population of the earth fell to about one thousand millions or less, and the average age receded to something about 23. This was a stupendous recession, not merely in numbers but in the maturity of the average mind.
Then came the Air and Sea Control and the First and the Second Council with their restoration of hygienic conditions and their scientific planning. The increase of population was watched and restrained for a century, but the average age extended until now it is 62 and still rising. The population total crept back to 1500 millions in 2060 and reached 2000 millions again in 2085. It has become manifest that such a population is no longer unwieldy, and that with the scientific education and behaviour control we now possess a considerable further increase can be contemplated without dismay.
The population of the earth is now 2500 millions, and it will probably be let up to 4000 millions as rapidly as the world is keyed up for its full support and happiness. The danger of such a population swarming dangerously or getting into panics, mental jams, crushes and insanitary congestions grows less and less. The opinion of contemporary authorities is that 4000 millions is an optimum, and that before many decades have passed it will be possible to keep most of those born actively and happily alive to something like 90 years of age. But the question of the possibility and advisability of prolonging the individual life more than three or four decades beyond the “threescore and ten” of the Biblical barbarian is still an open one. It is possible that there is a limit to the memories a brain can carry and to its power of taking new interest in fresh events. There may be a natural death for most people in the future about the age of a hundred or a little more, as painless and acceptable as going to bed and sleeping after a long and interesting day.
These quantitative biological alterations involve the profoundest differences in the quality of every life concerned. It is not simply that each individual has now a justifiable faith that he will live out his life to the end, but that the conditions in which he lives call out quite a different reaction system from that evoked in the past. Before the Middle Ages people thought of their grandparents as older and mightier people, but we think of our ancestors as younger and feebler people. Those earlier generations were like fresh-water fish, living in shallow, saline and readily dried-up water, in comparison with others of the same species living in a deep, abundant, well-aerated and altogether congenial lake. They were continually uncomfortable, constantly stranded by circumstances; they flapped about wildly and died early. Although they were the same in essence, their behaviour, their very movements, were like the behaviour of a different species of being.
Consider the existence of a young man in Shakespeare’s time. If he did not die young he aged rapidly. He would be heavy, old and pompous at forty. A swarm of ailments lay in wait for him to emphasize and accelerate his decay. Youth was stuff that would not endure. The beauty and vitality of women were even more evanescent. So they snatched at love and adventure. The world was full of Romeos and Juliets at the crest of their passionate lives in their teens, who nowadays would be in the college stage of education, a score of years away from any conclusive drama. The literature of the time witnesses to a universal normal swift transitoriness. The simple precipitate love story, the jealousy, the headlong revenge and so on makes the substances of drama, romance and poem. That and the grab at spendable wealth: El Dorado, treasure trove or robbery attempted and defeated. A career was made or marred by a week’s folly, and there was little time to recover it before the end. It is extraordinarily interesting to note all the things in life that are left out by the Elizabethan literature, and so to measure that smaller brighter circle of interest in that age.
The changing biological conditions between 1840 and 1940 mirror themselves faithfully in the art and reading of the decades. The novel, which is at first pervaded by a gay hello to life, which accepts everything as cheerfully as a young animal, which laughs, caricatures and incites, becomes reflective, analytical, purposeful. Life no longer ends at the first rush. The proportion of novels to other books diminishes. The penetration of the individual consciousness by the great social and economic processes that were going on becomes more and more evident. When literature revived at the close of the twentieth century it was an adult literature, expressing the mentality of readers and writers who were fully grown men and women in a planning world that had ceased to be accidental and incoherent. In the novel as it then reappeared there is much more about personal love and the interplay of character, but far less (and the proportion continues to diminish) about the primary love adventure.
That diminution of haste and avidity, of the quick egotism and swift uncritical judgment of youth, still continues. The deliberation, serenity and breadth of reference in the normal life increase. The years from thirty to seventy were formerly a sort of dump for the consequences of the first three decades; now they are the main part of life, the years of work, expression and complete self-discovery, to which these earlier stages are the bright, delightful prelude. There was a time when the man or woman over forty felt something of a survivor; he was “staying on”; relatively the world swarmed with youth, with the swiftness, rivalries and shallowness of youth: the fitness of the ill-protected body had gone already; the elderly people who were “getting on for fifty” moved slowly and had duller if sounder apprehensions. But now most of us are in the graver years with our bodies and apprehensions unimpaired, and there is no longer the same effect of being rather in the way of a juvenile treat. The juvenile treat, the age when even the old aped the young, ended in the World War and the economic collapse. After that came a struggle, at first unconscious and then open and declared, between youth and mental maturity.
In the bad years after the World War for a couple of generations there was a very unhappy relapse towards youthful predominance. The old people had failed to avert the collapse, the legitimate seniors for the new period were dead and broken and morally disorganized, and there was a sort of poetic justice in the stormy release of puerility that ensued. Italy was scourged by its hobbledehoys in black shirts; Russia was ruled by the blue-chinned Young; Ireland was devastated by hooligan patriots; presently Germany, after brooding over its defeat for ten years, had a convulsive relapse to fiercely crazy boyishness in the Nazis. Indian patriotism had a kindred immaturity. The tender years of many of the young revolutionaries executed by the
