Chapter 9

Then in the physiology of these children of men, with their expanding brains, their great sensitive hands and diminishing bodies, great changes were necessarily worked. "We see now," says the Professor, "in the more intellectual sections of humanity an increasing sensitiveness to stimulants, a growing inability to grapple with such a matter as alcohol, for instance. No longer can men drink a bottleful of port; some cannot drink tea; it is too exciting for their highly-wrought nervous systems. The process will go on, and the Sir Wilfrid Lawson of some near generation may find it his duty and pleasure to make the silvery spray of his wisdom tintinnabulate against the tea-tray. These facts lead naturally to the comprehension of others. Fresh raw meat was once a dish for a king. Now refined persons scarcely touch meat unless it is cunningly disguised. Again, consider the case of turnips; the raw root is now a thing almost uneatable, but once upon a time a turnip must have been a rare and fortunate find, to be torn up with delirious eagerness and devoured in ecstasy. The time will come when the change will affect all the other fruits of the earth. Even now, only the young of mankind eat apples raw--the young always preserving ancestral characteristics after their disappearance in the adult. Some day even boys will regard apples without emotion. The boy of the future, one must believe, will gaze on an apple with the same unspeculative languor with which he now regards a flint"--in the absence of a cat.

"Furthermore, fresh chemical discoveries came into action as modifying influences upon men. In the prehistoric period even, man's mouth had ceased to be an instrument for grasping food; it is still growing continually less prehensile, his front teeth are smaller, his lips thinner and less muscular; he has a new organ, a mandible not of irreparable tissue, but of bone and steel--a knife and fork. There is no reason why things should stop at partial artificial division thus afforded; there is every reason, on the contrary, to believe my statement that some cunning exterior mechanism will presently masticate and insalivate his dinner, relieve his diminishing salivary glands and teeth, and at last altogether abolish them."

Then what is not needed disappears. What use is there for external ears, nose, and brow ridges now? The two latter once protected the eye from injury in conflict and in falls, but in these days we keep on our legs, and at peace. Directing his thoughts in this way, the reader may presently conjure up a dim, strange vision of the latter-day face: "Eyes large, lustrous, beautiful, soulful; above them, no longer separated by rugged brow ridges, is the top of the head, a glistening, hairless dome, terete and beautiful; no craggy nose rises to disturb by its unmeaning shadows the symmetry of that calm face, no vestigial ears project; the mouth is a small, perfectly round aperture, toothless and gumless, jawless, unanimal, no futile emotions disturbing its roundness as it lies, like the harvest moon or the evening star, in the wide firmament of face." Such is the face the Professor beholds in the future.

Of course parallel modifications will also affect the body and limbs. "Every day so many hours and so much energy are required for digestion; a gross torpidity, a carnal lethargy, seizes on mortal men after dinner. This may and can be avoided. Man's knowledge of organic chemistry widens daily. Already he can supplement the gastric glands by artificial devices. Every doctor who administers physic implies that the bodily functions may be artificially superseded. We have pepsine, pancreatine, artificial gastric acid--I know not what like mixtures. Why, then, should not the stomach be ultimately superannuated altogether? A man who could not only leave his dinner to be cooked, but also leave it to be masticated and digested, would have vast social advantages over his food-digesting fellow. This is, let me remind you here, the calmest, most passionless, and scientific working out of the future forms of things from the data of the present. At this stage the following facts may perhaps stimulate your imagination. There can be no doubt that many of the Arthropods, a division of animals more ancient and even now more prevalent than the Vertebrata, have undergone more phylogenetic modification"--a beautiful phrase--"than even the most modified of vertebrated animals. Simple forms like the lobsters display a primitive structure parallel with that of the fishes. However, in such a form as the degraded 'Chondracanthus,' the structure has diverged far more widely from its original type than in man. Among some of these most highly modified crustaceans the whole of the alimentary canal--that is, all the food-digesting and food-absorbing parts--form a useless solid cord: the animal is nourished--it is a parasite--by absorption of the nutritive fluid in which it swims. Is there any absolute impossibility in supposing man to be destined for a similar change; to imagine him no longer dining, with unwieldy paraphernalia of servants and plates, upon food queerly dyed and distorted, but nourishing himself in elegant simplicity by immersion in a tub of nutritive fluid?

"There grows upon the impatient imagination a building, a dome of crystal, across the translucent surface of which flushes of the most glorious and pure prismatic colours pass and fade and change. In the centre of this transparent chameleon-tinted dome is a circular white marble basin filled with some clear, mobile, amber liquid, and in this plunge and float strange beings. Are they birds?

"They are the descendants of man--at dinner. Watch them as they hop on their hands--a method of progression advocated already by Bjornsen--about the pure white marble floor. Great hands they have, enormous brains, soft, liquid, soulful eyes. Their whole muscular system, their legs, their abdomens, are shrivelled to nothing, a dangling, degraded pendant to their minds."

The further visions of the Professor are less alluring.

"The animals and plants die away before men, except such as he preserves for his food or delight, or such as maintain a precarious footing about him as commensals and parasites. These vermin and pests must succumb sooner or later to his untiring inventiveness and incessantly growing discipline. When he learns (the chemists are doubtless getting towards the secret now) to do the work of chlorophyll without the plant, then his necessity for other animals and plants upon the earth will disappear. Sooner or later, where there is no power of resistance and no necessity, there comes extinction. In the last days man will be alone on the earth, and his food will be won by the chemist from the dead rocks and the sunlight.

"And--one may learn the full reason in that explicit and painfully right book, the _Data of Ethics_--the irrational fellowship of man will give place to an intellectual co-operation, and emotion fall within the scheme of reason. Undoubtedly it is a long time yet, but a long time is nothing in the face of eternity, and every man who dares think of these things must look eternity in the face."

Then the earth is ever radiating away heat into space, the Professor reminds us. And so at last comes a vision of earthly cherubim, hopping heads, great unemotional intelligences, and little hearts, fighting together perforce and fiercely against the cold that grips them tighter and tighter. For the world is cooling--slowly and inevitably it grows colder as the years roll by. "We must imagine these creatures," says the Professor, "in galleries and laboratories deep down in the bowels of the earth. The whole world will be snow-covered and piled with ice; all animals, all vegetation vanished, except this last branch of the tree of life. The last men have gone even deeper, following the diminishing heat of the planet, and vast metallic shafts and ventilators make way for the air they need."

So with a glimpse of these human tadpoles, in their deep close gallery, with their boring machinery ringing away, and artificial lights glaring and casting black shadows, the Professor's horoscope concludes. Humanity in dismal retreat before the cold, changed beyond recognition. Yet the Professor is reasonable enough, his facts are current science, his methods orderly. The contemplative man shivers at the prospect, starts up to poke the fire, and the whole of this remarkable book that is not written vanishes straightway in the smoke of his pipe. This is the great advantage of this unwritten literature: there is no bother in changing the books. The contemplative man consoles himself for the destiny of the species with the lost portion of Kubla Khan.

THE EXTINCTION OF MAN

It is part of the excessive egotism of the human animal that the bare idea of its extinction seems incredible to it. "A world without _us_!" it says, as a heady young Cephalaspis might have said it in the old Silurian sea. But since the Cephalaspis and the Coccostëus many a fine animal has increased and multiplied upon the earth, lorded it over land or sea without a rival, and passed at last into the night. Surely it is not so unreasonable to ask why man should be an exception to the rule. From the scientific standpoint at least any reason for such exception is hard to find.

No doubt man is undisputed master at the present time--at least of most of the land surface; but so it has been before with other animals. Let us consider what light geology has to throw upon this. The great land and sea reptiles of the Mesozoic period, for instance, seem to have been as secure as humanity is now in their pre-eminence. But they passed away and left no descendants when the new orders of the mammals emerged from their obscurity. So, too, the huge Titanotheria of the American continent, and all the powerful mammals of Pleistocene South America, the sabre-toothed lion, for instance, and the Machrauchenia suddenly came to a finish when they were still almost at the zenith of their rule. _And in no case does the record of the fossils show a really dominant species succeeded by its own descendants._ What has usually happened in the past appears to be the emergence of some type of animal hitherto rare and unimportant, and the extinction, not simply of the previously ruling species, but of most of the forms that are at all closely related to it. Sometimes, indeed, as in the case of the extinct giants of South America, they vanished without any considerable rivals, victims of pestilence, famine, or, it may be, of that cumulative inefficiency that comes of a too undisputed life. So that the analogy of geology, at anyrate, is against this too acceptable view of man's certain tenure of the earth for the next few million years or so.

And, after all, even now man is by no means such a master of the kingdoms of life as he is apt to imagine. The sea, that mysterious nursery of living things, is for all practical purposes beyond his control. The low-water mark is his limit. Beyond that he may do a little with seine and dredge, murder a few million herrings a year as they come in to spawn, butcher his fellow air-breather, the whale, or haul now and then an unlucky king-crab or strange sea-urchin out of the deep water, in the name of science; but the life of the sea as a whole knows him not, plays out its slow drama of change and development unheeding him, and may in the end, in mere idle sport, throw up some new terrestrial denizens, some new competitor for space to live in and food to live upon, that will sweep him and all his little contrivances out of existence, as certainly and inevitably as he has swept away auk, bison, and dodo during the last two hundred years.

For instance, there are the Crustacea. As a group the crabs and lobsters are confined below the high-water mark. But experiments in air-breathing are no doubt in progress in this group--we already have tropical land-crabs--and as far as we know there is no reason why in the future these creatures should not increase in size and terrestrial capacity. In the past we have the evidence of the fossil _Paradoxides_ that creatures of this kind may at least attain a length of six feet, and, considering their intense pugnacity, a crab of such dimensions would be as formidable a creature as one could well imagine. And their amphibious capacity would give them an advantage against us such as at present is only to be found in the case of the alligator or crocodile. If we imagine a shark that could raid out upon the land, or a tiger that could take refuge in the sea, we should have a fair suggestion of what a terrible monster a large predatory crab might prove. And so far as zoological science goes we must, at least, admit that such a creature is an evolutionary possibility.

Then, again, the order of the Cephalopods, to which belong the cuttle-fish and the octopus (sacred to Victor Hugo), may be, for all we can say to the contrary, an order with a future. Their kindred, the Gastropods, have, in the case of the snail and slug, learnt the trick of air-breathing. And not improbably there are even now genera of this order that have escaped the naturalist, or even well-known genera whose possibilities in growth and dietary are still unknown. Suppose some day a specimen of a new species is caught off the coast of Kent. It excites remark at a Royal Society soirée, engenders a Science Note or so, "A Huge Octopus!" and in the next year or so three or four other specimens come to hand, and the thing becomes familiar. "Probably a new and larger variety of _Octopus_ so-and-so, hitherto supposed to be tropical," says Professor Gargoyle, and thinks he has disposed of it. Then conceive some mysterious boating accidents and deaths while bathing. A large animal of this kind coming into a region of frequent wrecks might so easily acquire a preferential taste for human nutriment, just as the Colorado beetle acquired a new taste for the common potato and gave up its old food-plants some years ago. Then perhaps a school or pack or flock of _Octopus gigas_ would be found busy picking the sailors off a stranded ship, and then in the course of a few score years it might begin to stroll up the beaches and batten on excursionists. Soon it would be a common feature of the watering-places--possibly at last commoner than excursionists. Suppose such a creature were to appear--and it is, we repeat, a possibility, if perhaps a remote one--how could it be fought against? Something might be done by torpedoes; but, so far as our past knowledge goes, man has no means of seriously diminishing the numbers of any animal of the most rudimentary intelligence that made its fastness in the sea.

Even on land it is possible to find creatures that with a little modification might become excessively dangerous to the human ascendency. Most people have read of the migratory ants of Central Africa, against which no man can stand. On the march they simply clear out whole villages, drive men and animals before them in headlong rout, and kill and eat every living creature they can capture. One wonders why they have not already spread the area of their devastations. But at present no doubt they have their natural checks, of ant-eating birds, or what not. In the near future it may be that the European immigrant, as he sets the balance of life swinging in his vigorous manner, may kill off these ant-eating animals, or otherwise unwittingly remove the checks that now keep these terrible little pests within limits. And once they begin to spread in real earnest, it is hard to see how their advance could be stopped. A world devoured by ants seems incredible now, simply because it is not within our experience; but a naturalist would have a dull imagination who could not see in the numerous species of ants, and in their already high intelligence, far more possibility of strange developments than we have in the solitary human animal. And no doubt the idea of the small and feeble organism of man, triumphant and omnipresent, would have seemed equally incredible to an intelligent mammoth or a palæolithic cave bear.

And, finally, there is always the prospect of a new disease. As yet science has scarcely touched more than the fringe of the probabilities associated with the minute fungi that constitute our zymotic diseases. But the bacilli have no more settled down into their final quiescence than have men; like ourselves, they are adapting themselves to new conditions and acquiring new powers. The plagues of the Middle Ages, for instance, seem to have been begotten of a strange bacillus engendered under conditions that sanitary science, in spite of its panacea of drainage, still admits are imperfectly understood, and for all we know even now we may be quite unwittingly evolving some new and more terrible plague--a plague that will not take ten or twenty or thirty per cent., as plagues have done in the past, but the entire hundred.

No; man's complacent assumption of the future is too confident. We think, because things have been easy for mankind as a whole for a generation or so, we are going on to perfect comfort and security in the future. We think that we shall always go to work at ten and leave off at four, and have dinner at seven for ever and ever. But these four suggestions, out of a host of others, must surely do a little against this complacency. Even now, for all we can tell, the coming terror may be crouching for its spring and the fall of humanity be at hand. In the case of every other predominant animal the world has ever seen, I repeat, the hour of its complete ascendency has been the eve of its entire overthrow. But if some poor story-writing man ventures to figure this sober probability in a tale, not a reviewer in London but will tell him his theme is the utterly impossible. And, when the thing happens, one may doubt if even then one will get the recognition one deserves.

THE WRITING OF ESSAYS

The art of the essayist is so simple, so entirely free from canons of criticism, and withal so delightful, that one must needs wonder why all men are not essayists. Perhaps people do not know how easy it is. Or perhaps beginners are misled. Rightly taught it may be learnt in a brief ten minutes or so, what art there is in it. And all the rest is as easy as wandering among woodlands on a bright morning in the spring.

Then sit you down if you would join us, taking paper, pens, and ink; and mark this, your pen is a matter of vital moment. For every pen writes its own sort of essay, and pencils also after their kind. The ink perhaps may have its influence too, and the paper; but paramount is the pen. This, indeed, is the fundamental secret of essay-writing. Wed any man to his proper pen, and the delights of composition and the birth of an essay are assured. Only many of us wander through the earth and never meet with her--futile and lonely men.

And, of all pens, your quill for essays that are literature. There is a subtle informality, a delightful easiness, perhaps even a faint immorality essentially literary, about the quill. The quill is rich in suggestion and quotation. There are quills that would quote you Montaigne and Horace in the hands of a trades-union delegate. And those quirky, idle noises this pen makes are delightful, and would break your easy fluency with wit. All the classical essayists wrote with a quill, and Addison used the most expensive kind the Government purchased. And the beginning of the inferior essay was the dawn of the cheap steel pen.

The quill nibs they sell to fit into ordinary pen-holders are no true quills at all, lacking dignity, and may even lead you into the New Humour if you trust overmuch to their use. After a proper quill commend me to a stumpy BB pencil; you get less polish and broader effects, but you are still doing good literature. Sometimes the work is close--Mr. George Meredith, for instance, is suspected of a soft pencil--and always it is blunter than quill work and more terse. With a hard pencil no man can write anything but a graceless style--a kind of east wind air it gives--and smile you cannot. So that it is often used for serious articles in the half-crown reviews.

There follows the host of steel pens. That bald, clear, scientific style, all set about with words like "evolution" and "environment," which aims at expressing its meaning with precision and an exemplary economy of words, is done with fine steel nibs--twelve a penny at any stationer's. The J pen to the lady novelist, and the stylograph to the devil--your essayist must not touch the things. So much for the pen. If you cannot write essays easily, that is where the hitch comes in. Get a box of a different kind of pen and begin again, and so on again and again until despair or joy arrests you.

As for a typewriter, you could no more get an essay out of a typewriter than you could play a sonata upon its keys. No essay was ever written with a typewriter yet, nor ever will be. Besides its impossibility, the suggestion implies a brutal disregard of the division of labour by which we live and move and have our being. If the essayist typewrite, the unemployed typewriter, who is commonly a person of superior education and capacity, might take to essays, and where is your living then? One might as reasonably start at once with the Linotype and print one's wit and humour straight away. And taking the invasion of other trades one step further one might, after an attempt to sell one's own newspaper, even get to the pitch of having to read it oneself. No; even essayists must be reasonable. If its mechanical clitter-clatter did not render composition impossible, the typewriter would still be beneath the honour of a literary man.

Then for the paper. The luxurious, expensive, small-sized cream-laid note is best, since it makes your essay choice and compact; and, failing that, ripped envelopes and the backs of bills. Some men love ruled paper, because they can write athwart the lines, and some take the fly-leaves of their friends' books. But whosoever writes on cheap sermon paper full of hairs should write far away from the woman he loves, lest he offend her ears. It is good, however, for a terse, forcible style.

The ink should be glossy black as it leaves your pen, for polished English. Violet inks lead to sham sentiment, and blue-black to vulgarity. Red ink essays are often good, but usually unfit for publication.

This is as much almost as anyone need know to begin essay writing. Given your proper pen and ink, or pencil and paper, you simply sit down and write the thing. The value of an essay is not its matter, but its mood. You must be comfortable, of course; an easy-chair with arm-rests, slippers, and a book to write upon are usually employed, and you must be fed recently, and your body clothed with ease rather than grandeur. For the rest, do not trouble to stick to your subject, or any subject; and take no thought for the editor or the reader, for your essay should be as spontaneous as the lilies of the field.

So long as you do not begin with a definition you may begin anyhow. An abrupt beginning is much admired, after the fashion of the clown's entry through the chemist's window. Then whack at your reader at once, hit him over the head with the sausages, brisk him up with the poker, bundle him into the wheelbarrow, and so carry him away with you before he knows where you are. You can do what you like with a reader then, if you only keep him nicely on the move. So long as you are happy your reader will be so too. But one law must be observed: an essay, like a dog that wishes to please, must have a lively tail, short but as waggish as possible. Like a rocket, an essay goes only with fizzle and sparks at the end of it. And, know, that to stop writing is the secret of writing an essay; the essay that the public loves dies young.
