XIV Neptune
1. BIRD’S-EYE VIEW
I have told man’s story up to a point about half-way from his origin to his annihilation. Behind lies the vast span which includes the whole Terrestrial and Venerian ages, with all their slow fluctuations of darkness and enlightenment. Ahead lies the Neptunian age, equally long, equally tragic perhaps, but more diverse, and in its last phase incomparably more brilliant. It would not be profitable to recount the history of man on Neptune on the scale of the preceding chronicle. Very much of it would be incomprehensible to terrestrials, and much of it repeats again and again, in the many Neptunian modes, themes that we have already observed in the Terrestrial or the Venerian movements of the human symphony. To appreciate fully the range and subtlety of the great living epic, we ought, no doubt, to dwell on its every movement with the same faithful care. But this is impossible to any human mind. We can but attend to significant phrases, here and there, and hope to capture some fragmentary hint of its vast intricate form. And for the readers of this book, who are themselves tremors in the opening bars of the music, it is best that I should dwell chiefly on things near to them, even at the cost of ignoring much that is in fact greater.
Before continuing our long flight let us look around us. Hitherto we have passed over time’s fields at a fairly low altitude, making many detailed observations. Now we shall travel at a greater height and with speed of a new order. We must therefore orientate ourselves within the wider horizon that opens around us; we must consider things from the astronomical rather than the human point of view. I said that we were half-way from man’s beginning to his end. Looking back to that remote beginning we see that the span of time which includes the whole career of the First Men from Pithecanthropus to the Patagonian disaster is an unanalysable point. Even the preceding and much longer period between the first mammal and the first man, some twenty-five millions of terrestrial years, seems now inconsiderable. The whole of it, together with the age of the First Men, may be said to lie half-way between the formation of the planets, two thousand million years earlier, and their final destruction, two thousand million years later. Taking a still wider view, we see that this aeon of four thousand million years is itself no more than a moment in comparison with the sun’s age. And before the birth of the suns the stuff of this galaxy had already endured for aeons as a nebula. Yet even these aeons look brief in relation to the passage of time before the myriad great nebulae themselves, the future galaxies, condensed out of the all-pervading mist in the beginning. Thus the whole duration of humanity, with its many sequent species and its incessant downpour of generations, is but a flash in the lifetime of the cosmos.
Spatially, also, man is inconceivably minute. If in imagination we reduce this galaxy of ours to the size of an ancient terrestrial principality, we must suppose it adrift in the void with millions of other such principalities, very remote from one another. On the same scale the all-embracing cosmos would bulk as a sphere whose diameter was some twenty times greater than that of the lunar orbit in your day; and somewhere within the little wandering asteroid-like principality which is our own universe, the solar system would be an ultra-microscopic point, the greatest planet incomparably smaller.
We have watched the fortunes of eight successive human species for a thousand million years, the first half of that flicker which is the duration of man. Ten more species now succeed one another, or are contemporary, on the plains of Neptune. We, the Last Men, are the Eighteenth Men. Of the eight pre-Neptunian species, some, as we have seen, remained always primitive; many achieved at least a confused and fleeting civilization, and one, the brilliant Fifth, was already wakening into true humanity when misfortune crushed it. The ten Neptunian species show an even greater diversity. They range from the instinctive animal to modes of consciousness never before attained. The definitely subhuman degenerate types are confined mostly to the first six hundred million years of man’s sojourn on Neptune. During the earlier half of this long phase of preparation, man, at first almost crushed out of existence by a hostile environment, gradually peopled the huge north; but with beasts, not men. For man, as man, no longer existed. During the latter half of the preparatory six hundred million years, the human spirit gradually awoke again, to undergo the fluctuating advance and decline characteristic of the pre-Neptunian ages. But subsequently, in the last four hundred million years of his career on Neptune, man has made an almost steady progress toward full spiritual maturity.
Let us now look rather more closely at these three great epochs of man’s history.
2. DA CAPO
It was in desperate haste that the last Venerian men had designed and fashioned the new species for the colonization of Neptune. The mere remoteness of the great planet, moreover, had prevented its nature from being explored at all thoroughly, and so the new human organism was but partially adapted to its destined environment. Inevitably it was a dwarf type, limited in size by the necessity of resisting an excessive gravitation. Its brain was so cramped that everything but the bare essentials of humanity had to be omitted from it. Even so, the Ninth Men were too delicately organized to withstand the ferocity of natural forces on Neptune. This ferocity the designers had seriously underestimated; and so they were content merely to produce a miniature copy of their own type. They should have planned a hardy brute, lustily procreative, cunning in the struggle for physical existence, but above all tough, prolific, and so insensitive as to be scarcely worthy of the name man. They should have trusted that if once this crude seed could take root, natural forces themselves would in time conjure from it something more human. Instead, they produced a race cursed with the inevitable fragility of miniatures, and designed for a civilized environment which feeble spirits could not possibly maintain in a tumultuous world. For it so happened that the still youthful giant, Neptune, was slowly entering one of his phases of crustal shrinkage, and therefore of earthquake and eruption. Thus the frail colonists found themselves increasingly in danger of being swallowed in sudden fiery crevasses or buried under volcanic dust. Moreover, their squat buildings, when not actually being trampled by lava streams, or warped and cracked by their shifting foundations, were liable to be demolished by the battering-ram thrust of a turbulent and massive atmosphere. Further, the atmosphere’s unwholesome composition killed all possibility of cheerfulness and courage in a race whose nature was doomed to be, even in favourable circumstances, neurotic.
Fortunately this agony could not last indefinitely. Little by little, civilization crumbled into savagery, the torturing vision of better things was lost, man’s consciousness was narrowed and coarsened into brute-consciousness. By good luck the brute precariously survived.
Long after the Ninth Men had fallen from man’s estate, nature herself, in her own slow and blundering manner, succeeded where man had failed. The brute descendants of this human species became at length well adapted to their world. In time there arose a wealth of subhuman forms in the many kinds of environment afforded by the lands and seas of Neptune. None of them penetrated far towards the Equator, for the swollen sun had rendered the tropics at this time far too hot to support life of any kind. Even at the pole the protracted summer put a great strain on all but the most hardy creatures.
Neptune’s year was at this time about one hundred and sixty-five times the length of the old terrestrial year. The slow seasonal change had an important effect on life’s own rhythms. All but the most ephemeral organisms tended to live through at least one complete year, and the higher mammals survived longer. At a much later stage this natural longevity
