Guesses at the undiscovered must necessarily be vague, but my antic.i.p.ations fall into two groups, and first I am disposed to expect a great systematic increment in individual human power. We probably have no suspicion as yet of what may be done with the human body and mind by way of enhancing its effectiveness I remember talking to the late Sir Michael Foster upon the possibilities of modern surgery, and how he confessed that he did not dare for his reputation"s sake tell ordinary people the things he believed would some day become matter-of-fact operations. In that respect I think he spoke for very many of his colleagues. It is already possible to remove almost any portion of the human body, including, if needful, large sections of the brain; it is possible to graft living flesh on living flesh, make new connections, mould, displace, and rearrange. It is also not impossible to provoke local hypertrophy, and not only by knife and physical treatment but by the subtler methods of hypnotism, profound changes can be wrought in the essential structure of a human being. If only our knowledge of function and value were at all adequate, we could correct and develop ourselves in the most extraordinary way. Our knowledge is not adequate, but it may not always remain inadequate.
We have already had some very astonishing suggestions in this direction from Doctor Metchnikoff. He regards the human stomach and large intestine as not only vestigial and superfluous in the human economy, but as positively dangerous on account of the harbour they afford for those bacteria that accelerate the decay of age. He proposes that these viscera should be removed. To a layman like myself this is an altogether astounding and horrifying idea, but Doctor Metchnikoff is a man of the very greatest scientific reputation, and it does not give him any qualm of horror or absurdity to advance it. I am quite sure that if a gentleman called upon me "done up" in the way I am dimly suggesting, with most of the contents of his abdomen excavated, his lungs and heart probably enlarged and improved, parts of his brain removed to eliminate harmful tendencies and make room for the expansion of the remainder, his mind and sensibilities increased, and his liability to fatigue and the need of sleep abolished, I should conceal with the utmost difficulty my inexpressible disgust and terror. But, then, if M. Bleriot, with his flying machine, ear-flaps and goggles, had soared down in the year 54 B.C., let us say, upon my woad-adorned ancestors--every family man in Britain was my ancestor in those days--at Dover, they would have had entirely similar emotions. And at present I am not discussing what is beautiful in humanity, but what is possible--and what, being possible, is likely to be attempted.
It does not follow that because men will some day have this enormous power over themselves, physically and mentally, that they will necessarily make themselves horrible--even by our present standards quite a lot of us would be all the slenderer and more active and graceful for "Metchnikoffing"--nor does surgery exhaust the available methods. We are still in the barbaric age, so far as our use of food and drugs is concerned. We stuff all sorts of substances into our unfortunate interiors and blunder upon the most various consequences.
Few people of three score and ten but have spent in the aggregate the best part of a year in a state of indigestion, stupid, angry or painful indigestion as the case may be. No one would be so careless and ignorant about the fuel he burnt in his motor-car as most of us are about the fuel we burn in our bodies. And there are all sort of stimulating and exhilarating things, digesting things, fatigue-suppressing things, exercise economising things, we dare not use because we are afraid of our ignorance of their precise working. There seems no reason to suppose that human life, properly understood and controlled, could not be a constant succession of delightful and for the most part active bodily and mental phases. It is sheer ignorance and bad management that keep the majority of people in that disagreeable system of states which we indicate by saying we are "a bit off colour" or a little "out of training." It may seem madly Utopian now to suggest that practically everyone in the community might be clean, beautiful, incessantly active, "fit," and long-lived, with the marks of all the surgery they have undergone quite healed and hidden, but not more madly Utopian than it would have seemed to King Alfred the Great if one had said that practically everyone in this country, down to the very swineherds, should be able to read and write.
Metchnikoff has speculated upon the possibility of delaying old age, and I do not see why his method should not be applied to the diurnal need of sleep. No vital process seems to be absolutely fated in itself; it is a thing conditioned and capable of modification. If Metchnikoff is right--and to a certain extent he must be right--the decay of age is due to changing organic processes that may be checked and delayed and modified by suitable food and regimen. He holds out hope of a new phase in the human cycle, after the phase of struggle and pa.s.sion, a phase of serene intellectual activity, old age with all its experience and none of its infirmities. Still more are fatigue and the need for repose dependent upon chemical changes in the body. It would seem we are unable to maintain exertion, partly through the exhaustion of our tissues, but far more by the loading of our blood with fatigue products--a recuperative interlude must ensue. But there is no reason to suppose that the usual food of to-day is the most rapidly a.s.similable nurture possible, that a rapidly digestible or injectable substance is not conceivable that would vastly accelerate repair, nor that the elimination and neutralisation of fatigue products might not also be enormously hastened. There is no inherent impossibility in the idea not only of various glands being induced to function in a modified manner, but even in the insertion upon the circulation of interceptors and artificial glandular structures. No doubt that may strike even an adventurous surgeon as chimerical, but consider what people, even authoritative people, were saying of flying and electric traction twenty years ago. At present a man probably does not get more than three or four hours of maximum mental and physical efficiency in the day. Few men can keep at their best in either physical or intellectual work for so long as that. The rest of the time goes in feeding, digesting, sleeping, sitting about, relaxation of various kinds. It is quite possible that science may set itself presently to extend systematically that proportion of efficient time. The area of maximum efficiency may invade the periods now demanded by digestion, sleep, exercise, so that at last nearly the whole of a man"s twenty-four hours will be concentrated on his primary interests instead of dispersed among these secondary necessary matters.
Please understand I do not consider this concentration of activity and these vast "artificialisations" of the human body as attractive or desirable things. At the first proposal much of this tampering with the natural stuff of life will strike anyone, I think, as ugly and horrible, just as seeing a little child, green-white and still under an anaesthetic, gripped my heart much more dreadfully than the sight of the same child actively bawling with pain. But the business of this paper is to discuss things that may happen, and not to evolve dreams of loveliness. Perhaps things of this kind will be manageable without dreadfulness. Perhaps man will come to such wisdom that neither the knife nor the drugs nor any of the powers which science thrusts into his hand will slay the beauty of life for him. Suppose we a.s.sume that he is not such a fool as to let that happen, and that ultimately he will emerge triumphant with all these powers utilised and controlled.
It is not only that an amplifying science may give mankind happier bodies and far more active and eventful lives, but that psychology and educational and social science, reinforcing literature and working through literature and art, may dare to establish serenities in his soul. For surely no one who has lived, no one who has watched sin and crime and punishment, but must have come to realise the enormous amount of misbehaviour that is mere ignorance and want of mental scope. For my own part I have never believed in the devil. And it may be a greater undertaking but no more impossible to make ways to goodwill and a good heart in men than it is to tunnel mountains and d.y.k.e back the sea. The way that led from the darkness of the cave to the electric light is the way that will lead to light in the souls of men, that is to say, the way of free and fearless thinking, free and fearless experiment, organised exchange of thoughts and results, and patience and persistence and a sort of intellectual civility.
And with the development of philosophical and scientific method that will go on with this great increase in man"s control over himself, another issue that is now a mere pious aspiration above abysses of ignorance and difficulty, will come to be a manageable matter. It has been the perpetual wonder of philosophers from Plato onward that men have bred their dogs and horses and left any man or woman, however vile, free to bear offspring in the next generation of men. Still that goes on. Beautiful and wonderful people die childless and bury their treasure in the grave, and we rest content with a system of matrimony that seems designed to perpetuate mediocrity. A day will come when men will be in possession of knowledge and opportunity that will enable them to master this position, and then certainly will it be a.s.sured that every generation shall be born better than was the one before it. And with that the history of humanity will enter upon a new phase, a phase which will be to our lives as daylight is to the dreaming of a child as yet unborn.
THE HUMAN ADVENTURE
Alone among all the living things this globe has borne, man reckons with destiny. All other living things obey the forces that created them; and when the mood of the power changes, submit themselves pa.s.sively to extinction Man only looks upon those forces in the face, antic.i.p.ates the exhaustion of Nature"s kindliness, seeks weapons to defend himself. Last of the children of Saturn, he escapes their general doom. He dispossesses his begetter of all possibility of replacement, and grasps the sceptre of the world. Before man the great and prevalent creatures followed one another processionally to extinction; the early monsters of the ancient seas, the clumsy amphibians struggling breathless to the land, the reptiles, the theriomorpha and the dinosaurs, the bat-winged reptiles of the Mesozoic forests, the colossal grotesque first mammals, the giant sloths, the mastodons and mammoths; it is as if some idle dreamer moulded them and broke them and cast them aside, until at last comes man and seizes the creative wrist that would wipe him out of being again.
There is nothing else in all the world that so turns against the powers that have made it, unless it be man"s follower fire. But fire is witless; a little stream, a changing breeze can stop it. Man circ.u.mvents. If fire were human it would build boats across the rivers and outmanoeuvre the wind. It would lie in wait in sheltered places, smouldering, husbanding its fuel until the gra.s.s was yellow and the forests sere. But fire is a mere creature of man"s; our world before his coming knew nothing of it in any of its habitable places, never saw it except in the lightning flash or remotely on some volcanic coronet. Man brought it into the commerce of life, a shining, resentful slave, to hound off the startled beasts from his sleeping-place and serve him like a dog.
Suppose that some enduring intelligence watched through the ages the successions of life upon this planet, marked the spreading first of this species and then that, the conflicts, the adaptations, the predominances, the dyings away, and conceive how it would have witnessed this strange dramatic emergence of a rare great ape to manhood. To such a mind the creature would have seemed at first no more than one of several varieties of clambering frugivorous mammals, a little distinguished by a disposition to help his clumsy walking with a stake and reinforce his fist with a stone. The foreground of the picture would have been filled by the rhinoceros and mammoth, the great herds of ruminants, the sabre-toothed lion and the big bears. Then presently the observer would have noted a peculiar increasing handiness about the obscurer type, an unwonted intelligence growing behind its eyes. He would have perceived a disposition in this creature no beast had shown before, a disposition to make itself independent of the conditions of climate and the chances of the seasons. Did shelter fail among the trees and rocks, this curious new thing-began to make itself harbours of its own; was food irregular, it multiplied food. It began to spread out from its original circ.u.mstances, fitting itself to novel needs, leaving the forests, invading the plains, following the watercourses upward and downward, presently carrying the smoke of its fires like a banner of conquest into wintry desolations and the high places of the earth.
The first onset of man must have been comparatively slow, the first advances needed long ages. By small degrees it gathered pace. The stride from the scattered savagery of the earlier stone period to the first cities, historically a vast interval, would have seemed to that still watcher, measuring by the standards of astronomy and the rise and decline of races and genera and orders, a, step almost abrupt. It took, perhaps, a thousand generations or so to make it. In that interval man pa.s.sed from an animal-like obedience to the climate and the weather and his own instincts, from living in small family parties of a score or so over restricted areas of indulgent country, to permanent settlements, to the life of tribal and national communities and the beginnings of cities. He had spread in that fragment of time over great areas of the earth"s surface, and now he was adapting himself to the Arctic circle on the one hand and to the life of the tropics on the other; he had invented the plough and the ship, and subjugated most of the domestic animals; he was beginning to think of the origin of the world and the mysteries of being. Writing had added its enduring records to oral tradition, and he was already making roads. Another five or six hundred generations at most bring him to ourselves. We sweep into the field of that looker-on, the momentary incarnations of this sempiternal being, Man. And after us there comes--
A curtain falls.
The time in which we, whose minds meet here in this writing, were born and live and die, would be to that imagined observer a mere instant"s phase in the swarming liberation of our kind from ancient imperatives.
It would seem to him a phase of unprecedented swift change and expansion and achievement. In this last handful of years, electricity has ceased to be a curious toy, and now carries half mankind upon their daily journeys, it lights our cities till they outshine the moon and stars, and reduces to our service a score of hitherto unsuspected metals; we clamber to the pole of our globe, scale every mountain, soar into the air, learn how to overcome the malaria that barred our white races from the tropics, and how to draw the sting from a hundred such agents of death. Our old cities are being rebuilt in towering marble; great new cities rise to vie with them. Never, it would seem, has man been so various and busy and persistent, and there is no intimation of any check to the expansion of his energies.
And all this continually accelerated advance has come through the quickening and increase of man"s intelligence and its reinforcement through speech and writing. All this has come in spite of fierce instincts that make him the most combatant and destructive of animals, and in spite of the revenge Nature has attempted time after time for his rebellion against her routines, in the form of strange diseases and nearly universal pestilences. All this has come as a necessary consequence of the first obscure gleaming of deliberate thought and reason through the veil of his animal being. To begin with, he did not know what he was doing. He sought his more immediate satisfaction and safety and security. He still apprehends imperfectly the change that comes upon him. The illusion of separation that makes animal life, that is to say, pa.s.sionate competing and breeding and dying, possible, the blinkers Nature has put upon us that we may clash against and sharpen one another, still darken our eyes. We live not life as yet, but in millions of separated lives, still unaware except in rare moods of illumination that we are more than those fellow beasts of ours who drop off from the tree of life and perish alone. It is only in the last three or four thousand years, and through weak and tentative methods of expression, through clumsy cosmogonies and theologies, and with incalculable confusion and discoloration, that the human mind has felt its way towards its undying being in the race. Man still goes to war against himself, prepares fleets and armies and fortresses, like a sleep-walker who wounds himself, like some infatuated barbarian who hacks his own limbs with a knife.
But he awakens. The nightmares of empire and racial conflict and war, the grotesques of trade jealousy and tariffs, the primordial dream-stuff of lewdness and jealousy and cruelty, pale before the daylight which filters between his eyelids. In a little while we individuals will know ourselves surely for corpuscles in his being, for thoughts that come together out of strange wanderings into the coherence of a waking mind.
A few score generations ago all living things were in our ancestry. A few score generations ahead, and all mankind will be in sober fact descendants from our blood. In physical as in mental fact we separate persons, with all our difference and individuality, are but fragments, set apart for a little while in order that we may return to the general life again with fresh experiences and fresh acquirements, as bees return with pollen and nourishment to the fellowship of the hive.
And this Man, this wonderful child of old earth, who is ourselves in the measure of our hearts and minds, does but begin his adventure now.
Through all time henceforth he does but begin his adventure. This planet and its subjugation is but the dawn of his existence. In a little while he will reach out to the other planets, and take that greater fire, the sun, into his service. He will bring his solvent intelligence to bear upon the riddles of his individual interaction, trans.m.u.te jealousy and every pa.s.sion, control his own increase, select and breed for his embodiment a continually finer and stronger and wiser race. What none of us can think or will, save in a disconnected partiality, he will think and will collectively. Already some of us feel our merger with that greater life. There come moments when the thing shines out upon our thoughts. Sometimes in the dark sleepless solitudes of night, one ceases to be so-and-so, one ceases to bear a proper name, forgets one"s quarrels and vanities, forgives and understands one"s enemies and oneself, as one forgives and understands the quarrels of little children, knowing oneself indeed to be a being greater than one"s personal accidents, knowing oneself for Man on his planet, flying swiftly to unmeasured destinies through the starry stillnesses of s.p.a.ce.
