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 can not 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 the 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 thought 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
