A priest and a boy entered some time ago a hollow in the hills and passed into a sort of subterranean tunnel that led into a labyrinth of such sealed and secret corridors of rock. They crawled through cracks that seemed almost impassable, they crept through tunnels that might have been made for moles, they dropped into holes as hopeless as wells, they seemed to be burying themselves alive seven times over beyond the hope of resurrection. This is but the commonplace of all such courageous exploration; but what is needed here is some one who shall put such stories in the primary light, in which they are not commonplace. There is, for instance, something strangely symbolic in the accident that the first intruders into that sunken world were a priest and a boy, the types of the antiquity and of the youth of the world. But here I am even more concerned with the symbolism of the boy than with that of the priest. Nobody who remembers boyhood needs to be told what it might be to a boy to enter like Peter Pan under a roof of the roots of all the trees and go deeper and deeper, till he reach what William Morris called the very roots of the mountains. Suppose somebody, with that simple and unspoilt realism that is a part of innocence, to pursue that journey to its end, not for the sake of what he could deduce or demonstrate in some dusty magazine controversy, but simply for the sake of what he could see. What he did see at last was a cavern so far from the light of day that it might have been the legendary Domdaniel cavern that was under the floor of the sea. This secret chamber of rock, when illuminated after its long night of unnumbered ages, revealed on its walls large and sprawling outlines diversified with coloured earths; and when they followed the lines of them they recognised, across that vast and void of ages, the movement and the gesture of a man’s hand. They were drawings or paintings of animals; and they were drawn or painted not only by a man but by an artist. Under whatever archaic limitations, they showed that love of the long sweeping or the long wavering line which any man who has ever drawn or tried to draw will recognise; and about which no artist will allow himself to be contradicted by any scientist. They showed the experimental and adventurous spirit of the artist, the spirit that does not avoid but attempt difficult things; as where the draughtsman had represented the action of the stag when he swings his head clean round and noses towards his tail, an action familiar enough in the horse. But there are many modern animal-painters who would set themselves something of a task in rendering it truly. In this and twenty other details it is clear that the artist had watched animals with a certain interest and presumably a certain pleasure. In that sense it would seem that he was not only an artist but a naturalist; the sort of naturalist who is really natural.

Now it is needless to note, except in passing, that there is nothing whatever in the atmosphere of that cave to suggest the bleak and pessimistic atmosphere of that journalistic cave of the winds, that blows and bellows about us with countless echoes concerning the cave-man. So far as any human character can be hinted at by such traces of the past, that human character is quite human and even humane. It is certainly not the ideal of an inhuman character, like the abstraction invoked in popular science. When novelists and educationists and psychologists of all sorts talk about the cave-man, they never conceive him in connection with anything that is really in the cave. When the realist of the sex novel writes, ‘Red sparks danced in Dagmar Doubledick’s brain; he felt the spirit of the cave-man rising within him,’ the novelist’s readers would be very much disappointed if Dagmar only went off and drew large pictures of cows on the drawing-room wall. When the psychoanalyst writes to a patient, ‘The submerged instincts of the cave-man are doubtless prompting you to gratify a violent impulse,’ he does not refer to the impulse to paint in water-colours; or to make conscientious studies of how cattle swing their heads when they graze. Yet we do know for a fact that the cave-man did these mild and innocent things; and we have not the most minute speck of evidence that he did any of the violent and ferocious things. In other words, the cave-man as commonly presented to us is simply a myth or rather a muddle; for a myth has at least an imaginative outline of truth. The whole of the current way of talking is simply a confusion and a misunderstanding, founded on no sort of scientific evidence and valued only as an excuse for a very modern mood of anarchy. If any gentleman wants to knock a woman about, he can surely be a cad without taking away the character of the cave-man, about whom we know next to nothing except what we can gather from a few harmless and pleasing pictures on a wall.

But this is not the point about the pictures or the particular moral here to be drawn from them. That moral is something much larger and simpler, so large and simple that when it is first stated it will sound childish. And indeed it is in the highest sense childish; and that is why I have in this apologue in some sense seen it through the eyes of a child. It is the biggest of all the facts really facing the boy in the cavern; and is perhaps too big to be seen. If the boy was one of the flock of the priest, it may be presumed that he had been trained in a certain quality of common sense; that common sense that often comes to us in the form of tradition. In that case he would simply recognise the primitive man’s work as the work of a man, interesting but in no way incredible in being primitive. He would see what was there to see; and he would not be tempted into seeing what was not there, by any evolutionary excitement or fashionable speculation. If he had heard of such things he would admit, of course, that the speculations might be true and were not incompatible with the facts that were true. The artist may have had another side to his character besides that which he has alone left on record in his works of art. The primitive man may have taken a pleasure in beating women as well as in drawing animals; all we can say is that the drawings record the one but not the other. It may be true that when the cave-man’s finished jumping on his mother, or his wife as the case may be, he loves to hear the little brook a-gurgling, and also to watch the deer as they come down to drink at the brook. These things are not impossible, but they are irrelevant. The common sense of the child could confine itself to learning from the facts what the facts have to teach; and the pictures in the cave are very nearly all the facts there are. So far as that evidence goes, the child would be justified in assuming that a man had represented animals with rock and red ochre for the same reason as he himself was in the habit of trying to represent animals with charcoal and red chalk. The man had drawn a stag just as the child had drawn a horse; because it was fun. The man had drawn a stag with his head turned as the child had drawn a pig with his eyes shut; because it was difficult. The child and the man, being both human, would be united by the brotherhood of men; and the brotherhood of men is even nobler when it bridges the abyss of ages than when it bridges only the chasm of class. But anyhow he would see no evidence of the cave-man of crude evolutionism; because there is none to be seen. If somebody told him that the pictures had all been drawn by St. Francis of Assisi out of pure and saintly love of animals, there would be nothing in the cave to contradict it.

Indeed I once knew a lady who half-humorously suggested that the cave was a crèche, in which the babies were put to be specially safe, and that coloured animals were drawn on the walls to amuse them; very much as diagrams of elephants and giraffes adorn a modern infant school. And though this was but a jest, it does draw attention to some of the other assumptions that we make only too readily. The pictures do not prove even that the cave-men lived in caves, any more than the discovery of a wine-cellar in Balham (long after that suburb had been destroyed by human or divine wrath) would prove that the Victorian middle classes lived entirely underground. The cave might have had a special purpose like the cellar; it might have been a religious shrine or a refuge in war or the meeting-place of a secret society or all sorts of things. But it is quite true that its artistic decoration has much more of the atmosphere of a nursery than of any of these nightmares of anarchical fury and fear. I have conceived a child as standing in the cave; and it is easy to conceive any child, modern or immeasurably remote, as making a living gesture as if to pat the painted beasts upon the wall. In that gesture there is a foreshadowing, as we shall see later, of another cavern and another child.

But suppose the boy had not been taught by a priest but by a professor, by one of the professors who simplify the relation of men and beasts to a mere evolutionary variation. Suppose the boy saw himself, with the same simplicity and sincerity, as a mere Mowgli running with the pack of nature and roughly indistinguishable from the rest save by a relative and recent variation. What would be for him the simplest lesson of that strange stone picture-book? After all, it would come back to this; that he had dug very deep and found the place where a man had drawn a picture of a reindeer. But he would dig a good deal deeper before he found a place where a reindeer had drawn a picture of a man. That sounds like a truism, but in this connection it is really a very tremendous truth. He might descend to depths unthinkable, he might sink into sunken continents as strange as remote stars, he might find himself in the inside of the world as far from men as the other side of the moon; he might see in those cold chasms or colossal terraces of stone, traced in the faint hieroglyphic of the fossil, the ruins of lost dynasties of biological life, rather like the ruins of successive creations and separate universes than the stages in the story of one. He would find the trail of monsters blindly developing in directions outside all our common imagery of fish and bird; groping and grasping and touching life with every extravagant elongation of horn and tongue and tentacle; growing a forest of fantastic caricatures of the claw and the fin and the finger. But nowhere would he find one finger that had traced one significant line upon the sand; nowhere one claw that had even begun to scratch the faint suggestion of a form. To all appearance, the thing would be as unthinkable in all those countless cosmic variations of forgotten aeons as it would be in the beasts and birds before our eyes. The child would no more expect to see it than to see the cat scratch on the wall a vindictive caricature of the dog. The childish common sense would keep the most evolutionary child from expecting to see anything like that; yet in the traces of the rude and recently evolved ancestors of humanity he would have seen exactly that. It must surely strike him as strange that men so remote from him should be so near, and that beasts so near to him should be so remote. To his simplicity it must seem at least odd that he could not find any trace of the beginning of any arts among any animals. That is the simplest lesson to learn in the cavern of the coloured pictures; only it is too simple to be learnt. It is the simple truth that man does differ from the brutes in kind and not in degree; and the proof of it is here; that it sounds like a truism to say that the most primitive man drew a picture of a monkey, and that it sounds like a joke to say that the most intelligent monkey drew a picture of a man. Something of division and disproportion has appeared; and it is unique. Art is the signature of man.

That is the sort of simple truth with which a story of the beginnings ought really to begin. The evolutionist stands staring in the painted cavern at the things that are too large to be seen and too simple to be understood. He tries to deduce all sorts of other indirect and doubtful things from the details of the pictures, because he cannot see the primary significance of the whole; thin and theoretical deductions about the absence of religion or the presence of superstition; about tribal government and hunting and human sacrifice and heaven knows what. In the next chapter I shall try to trace in a little more detail the much disputed question about these prehistoric origins of human ideas and especially of the religious idea. Here I am only taking this one case of the cave as a sort of symbol of the simpler sort of truth with which the story ought to start. When all is said, the main fact that the record of the reindeer men attests, along with all other records, is that the reindeer man could draw and the reindeer could not. If the reindeer man was as much an animal as the reindeer, it was all the more extraordinary that he could do what all other animals could not. If he was an ordinary product of biological growth, like any other beast or bird, then it is all the more extraordinary that he was not in the least like any other beast or bird. He seems rather more supernatural as a natural product than as a supernatural one.

But I have begun this story in the cave, like the cave of the speculations of Plato, because it is a sort of model of the mistake of merely evolutionary introductions and prefaces. It is useless to begin by saying that everything was slow and smooth and a mere matter of development and degree. For in a plain matter like the pictures there is in fact not a trace of any such development or degree. Monkeys did not begin pictures and men finish them; Pithecanthropus did not draw a reindeer badly and Homo Sapiens draw it well. The higher animals did not draw better and better portraits; the dog did not paint better in his best period than in his early bad manner as a jackal; the wild horse was not an Impressionist and the race-horse a Post-Impressionist. All we can say of this notion of reproducing things in shadow or representative shape is that it exists nowhere in nature except in man; and that we cannot even talk about it without treating man as something separate from nature. In other words, every sane sort of history must begin with man as man, a thing standing absolute and alone. How he came there, or indeed how anything else came there, is a thing for theologians and philosophers and scientists and not for historians. But an excellent test case of this isolation and mystery is the matter of the impulse of art. This creature was truly different from all other creatures; because he was a creator as well as a creature. Nothing in that sense could be made in any other image but the image of man. But the truth is so true that, even in the absence of any religious belief, it must be assumed in the form of some moral or metaphysical principle. In the next chapter we shall see how this principle applies to all the historical hypotheses and evolutionary ethics now in fashion; to the origins of tribal government or mythological belief. But the clearest and most convenient example to start with is this popular one of what the cave-man really did in his cave. It means that somehow or other a new thing had appeared in the cavernous night of nature; a mind that is like a mirror. It is like a mirror because it is truly a thing of reflection. It is like a mirror because in it alone all the other shapes can be seen like shining shadows in a vision. Above all, it is like a mirror because it is the only thing of its kind. Other things may resemble it or resemble each other in various ways; other things may excel it or excel each other in various ways; just as in the furniture of a room a table may be round like a mirror or a cupboard may be larger than a mirror. But the mirror is the only thing that can contain them all. Man is the microcosm; man is the measure of all things; man is the image of God. These are the only real lessons to be learnt in the cave, and it is time to leave it for the open road.

It will be well in this place, however, to sum up once and for all what is meant by saying that man is at once the exception to everything and the mirror and the measure of all things. But to see man as he is, it is necessary once more to keep close to that simplicity that can clear itself of accumulated clouds of sophistry. The simplest truth about man is that he is a very strange being; almost in the sense of being a stranger on the earth. In all sobriety, he has much more of the external appearance of one bringing alien habits from another land than of a mere growth of this one. He has an unfair advantage and an unfair disadvantage. He cannot sleep in his own skin; he cannot trust his own instincts. He is at once a creator moving miraculous hands and fingers and a kind of cripple. He is wrapped in artificial bandages called clothes; he is propped on artificial crutches called furniture. His mind has the same doubtful liberties and the same wild limitations. Alone among the animals, he is shaken with the beautiful madness called laughter; as if he had caught sight of some secret in the very shape of the universe hidden from the universe itself. Alone among the animals he feels the need of averting his thoughts from the root realities of his own bodily being; of hiding them as in the presence of some higher possibility which creates the mystery of shame. Whether we praise these things as natural to man or abuse them as artificial in nature, they remain in the same sense unique. This is realised by the whole popular instinct called religion, until disturbed by pedants, especially the laborious pedants of the Simple Life. The most sophistical of all sophists are Gymnosophists.

It is not natural to see man as a natural product. It is not common sense to call man a common object of the country or the seashore. It is not seeing straight to see him as an animal. It is not sane. It sins against the light; against that broad daylight of proportion which is the principle of all reality. It is reached by stretching a point, by making out a case, by artificially selecting a certain light and shade, by bringing into prominence the lesser or lower things which may happen to be similar. The solid thing standing in the sunlight, the thing we can walk round and see from all sides, is quite different. It is also quite extraordinary; and the more sides we see of it the more extraordinary it seems. It is emphatically not a thing that follows or flows naturally from anything else. If we imagine that an inhuman or impersonal intelligence could have felt from the first the general nature of the non-human world sufficiently to see that things would evolve in whatever way they did evolve, there would have been nothing whatever in all that natural world to prepare such a mind for such an unnatural novelty. To such a mind, man would most certainly not have seemed something like one herd out of a hundred herds finding richer pasture; or one swallow out of a hundred swallows making a summer under a strange sky. It would not be in the same scale and scarcely in the same dimension. We might as truly say that it would not be in the same universe. It would be more like seeing one cow out of a hundred cows suddenly jump over the moon or one pig out of a hundred pigs grow wings in a flash and fly. It would not be a question of the cattle finding their own grazing-ground but of their building their own cattle-sheds, not a question of one swallow making a summer but of his making a summer-house. For the very fact that birds do build nests is one of those similarities that sharpen the startling difference. The very fact that a bird can get as far as building a nest, and cannot get any farther, proves that he has not a mind as man has a mind; it proves it more completely than if he built nothing at all. If he built nothing at all, he might possibly be a philosopher of the Quietist or Buddhistic school, indifferent to all but the mind within. But when he builds as he does build and is satisfied and sings aloud with satisfaction, then we know there is really an invisible veil like a pane of glass between him and us, like the window on which a bird will beat in vain. But suppose our abstract onlooker saw one of the birds begin to build as men build. Suppose in an incredibly short space of time there were seven styles of architecture for one style of nest. Suppose the bird carefully selected forked twigs and pointed leaves to express the piercing piety of Gothic, but turned to broad foliage and black mud when he sought in a darker mood to call up the heavy columns of Bel and Ashtaroth; making his nest indeed one of the hanging gardens of Babylon. Suppose the bird made little clay statues of birds celebrated in letters or politics and stuck them up in front of the nest. Suppose that one bird out of a thousand birds began to do one of the thousand things that man had already done even in the morning of the world; and we can be quite certain that the onlooker would not regard such a bird as a mere evolutionary variety of the other birds; he would regard it as a very fearful wild-fowl indeed; possibly as a bird of ill-omen, certainly as an omen. That bird would tell the augurs, not of something that would happen, but of something that had happened. That something would be the appearance of a mind with a new dimension of depth; a mind like that of man. If there be no God, no other mind could conceivably have foreseen it.

Now, as a matter of fact, there is not a shadow of evidence that this thing was evolved at all. There is not a particle of proof that this transition came slowly, or even that it came naturally. In a strictly scientific sense, we simply know nothing whatever about how it grew, or whether it grew, or what it is. There may be a broken trail of stones and bones faintly suggesting the development of the human body. There is nothing even faintly suggesting such a development of this human mind. It was not and it was; we know not in what instant or in what infinity of years. Something happened; and it has all the appearance of a transaction outside time. It has therefore nothing to do with history in the ordinary sense. The historian must take it or something like it for granted; it is not his business as a historian to explain it. But if he cannot explain it as a historian, he will not explain it as a biologist. In neither case is there any disgrace to him in accepting it without explaining it; for it is a reality, and history and biology deal with realities. He is quite justified in calmly confronting the pig with wings and the cow that jumped over the moon, merely because they have happened. He can reasonably accept man as a freak, because he accepts man as a fact. He can be perfectly comfortable in a crazy and disconnected world, or in a world that can produce such a crazy and disconnected thing. For reality is a thing in which we can all repose, even if it hardly seems related to anything else. The thing is there; and that is enough for most of us. But if we do indeed want to know how it can conceivably have come there, if we do indeed wish to see it related realistically to other things, if we do insist on seeing it evolved before our very eyes from an environment nearer to its own nature, then assuredly it is to very different things that we must go. We must stir very strange memories and return to very simple dreams if we desire some origin that can make man other than a monster. We shall have discovered very different causes before he becomes a creature of causation; and invoked other authority to turn him into something reasonable, or even into anything probable. That way lies all that is at once awful and familiar and forgotten, with dreadful faces thronged and fiery arms. We can accept man as a fact, if we are content with an unexplained fact. We can accept him as an animal, if we can live with a fabulous animal. But if we must needs have sequence and necessity, then indeed we must provide a prelude and crescendo of mounting miracles, that ushered in with unthinkable thunders in all the seven heavens of another order, a man may be an ordinary thing.
