The minimum of necessary work was performed, and there was even a certain dreamy zest in the performance, but nothing which would entail extra toil ever seemed worth while. And so, when adjustment to the new circumstances of the world had been achieved, complete stagnation set in. Practical intelligence was easily able to cope with a slowly changing environment, and even with sudden natural upheavals such as floods, earthquakes, and disease epidemics. Man remained in a sense master of his world, but he had no idea what to do with his mastery. It was everywhere assumed that the sane end of living was to spend as many days as possible in indolence, lying in the shade. Unfortunately human beings had, of course, many needs which were irksome if not appeased, and so a good deal of hard work had to be done. Hunger and thirst had to be satisfied. Other individuals beside oneself had to be cared for, since man was cursed with sympathy and with a sentiment for the welfare of his group. The only fully rational behaviour, it was thought, would be general suicide, but irrational impulses made this impossible. Beatific drugs offered a temporary heaven. But, far as the Second Men had fallen, they were still too clear-sighted to forget that such beatitude is outweighed by subsequent misery.
Century by century, epoch by epoch, man glided on in this seemingly precarious, yet actually unshakable equilibrium. Nothing that happened to him could disturb his easy dominance over the beasts and over physical nature; nothing could shock him out of his racial sleep. Long-drawn-out climatic changes made desert, jungle, and grass-land fluctuate like the clouds. As the years advanced by millions, ordinary geological processes, greatly accentuated by the immense strains set up by the Patagonian upheaval, remodelled the surface of the planet. Continents were submerged, or lifted out of the sea, till presently there was little of the old configuration. And along with these geological changes went changes in the fauna and flora. The bacterium which had almost exterminated man had also wrought havoc amongst other mammals. Once more the planet had to be re-stocked, this time from the few surviving tropical species. Once more there was a great remaking of old types, only less revolutionary than that which had followed the Patagonian disaster. And since the human race remained minute, through the effects of its spiritual fatigue, other species were favoured. Especially the ruminants and the large carnivora increased and diversified themselves into many habits and forms.
But the most remarkable of all the biological trains of events in this period was the history of the Martian subvital units that had been disseminated by the slaughter of the Martian colony, and had then tormented men and animals with pulmonary diseases. As the ages passed, certain species of mammals so readjusted themselves that the Martian virus became not only harmless but necessary to their well-being. A relationship which was originally that of parasite and host became in time a true symbiosis, a cooperative partnership, in which the terrestrial animals gained something of the unique attributes of the vanished Martian organisms. The time was to come when Man himself should look with envy on these creatures, and finally make use of the Martian ‘virus’ for his own enrichment.
But meanwhile, and for many million years, almost all kinds of life were on the move, save Man. Like a ship-wrecked sailor, he lay exhausted and asleep on his raft, long after the storm had abated.
But his stagnation was not absolute. Imperceptibly, he was drifting on the oceanic currents of life, and in a direction far out of his original course. Little by little, his habit was becoming simpler, less artificial, more animal. Agriculture faded out, since it was no longer necessary in the luxuriant garden where man lived. Weapons of defence and of the chase became more precisely adapted to their restricted purposes, but at the same time less diversified and more stereotyped. Speech almost vanished; for there was no novelty left in experience. Familiar facts and familiar emotions were conveyed increasingly by gestures which were mostly unwitting. Physically, the species had changed little. Though the natural period of life was greatly reduced, this was due less to physiological change than to a strange and fatal increase of absent-mindedness in middle-age. The individual gradually ceased to react to his environment; so that even if he escaped a violent death, he died of starvation.
Yet in spite of this great change, the species remained essentially human. There was no bestialization, such as had formerly produced a race of submen. These tranced remnants of the second human species were not beasts but innocents, simples, children of nature, perfectly adjusted to their simple life. In many ways their state was idyllic and enviable. But such was their dimmed mentality that they were never clearly aware even of the blessings they had, still less, of course, of the loftier experiences which had kindled and tortured their ancestors.
X The Third Men in the Wilderness
1. THE THIRD HUMAN SPECIES
We have now followed man’s career during some forty million years. The whole period to be covered by this chronicle is about two thousand million. In this chapter, and the next, therefore, we must accomplish a swift flight at great altitude over a tract of time more than three times as long as that which we have hitherto observed. This great expanse is no desert, but a continent teeming with variegated life, and many successive and very diverse civilizations. The myriads of human beings who inhabit it far outnumber the First and Second Men combined. And the content of each one of these lives is a universe, rich and poignant as that of any reader of this book.
In spite of the great diversity of this span of man’s history, it is a single movement within the whole symphony, just as the careers of the First and of the Second Men are each a single movement. Not only is it a period dominated by a single natural human species and the artificial human species into which the natural species at length transformed itself; but, also, in spite of innumerable digressions, a single theme, a single mood of the human will, informs the whole duration. For now at last man’s main energy is devoted to remaking his own physical and mental nature. Throughout the rise and fall of many successive cultures this purpose is progressively clarifying itself, and expressing itself in many tragic and even devastating experiments; until, towards the close of this immense period, it seems almost to achieve its end.
When the Second Men had remained in their strange racial trance for about thirty million years, the obscure forces that make for advancement began to stir in them once more. This reawakening was favoured by geological accident. An incursion of the sea gradually isolated some of their number in an island continent, which was once part of the North Atlantic ocean-bed. The climate of this island gradually cooled from sub-tropical to temperate and sub-arctic. The vast change of conditions caused in the imprisoned race a subtle chemical re-arrangement of the germ-plasm, such that there ensued an epidemic of biological variation. Many new types appeared, but in the long run one, more vigorous and better adapted than the rest, crowded out all competitors and slowly consolidated itself as a new species, the Third Men.
