SCIENCE is weak about these prehistoric things in a way that has hardly been noticed. The science whose modern marvels we all admire succeeds by incessantly adding to its data. In all practical inventions, in most natural discoveries, it can always increase evidence by experiment. But it cannot experiment in making men; or even in watching to see what the first men make. An inventor can advance step by step in the construction of an airplane even if he is only experimenting with sticks and scraps of metal in his own backyard. But he cannot watch the Missing Link evolving in his own backyard. If he has made a mistake in his calculations, the airplane will correct it by crashing to the ground. But if he has made a mistake about the arboreal habitat of his ancestor, he cannot see his arboreal ancestor falling off the tree. He cannot keep a caveman like a cat in the backyard and watch him to see whether he does really practice cannibalism or carry off his mate on the principles of marriage by capture. He cannot keep a tribe of primitive men like a pack of hounds and notice how far they are influenced by the herd instinct. If he sees a particular bird behave in a particular way, he can get other birds and see if they behave in that way; but if be finds a skull, or the scrap of a skull in the hollow of a hill, he cannot multiply it into a vision of the valley of dry bones. In dealing with a past that has almost entirely perished he can only go by evidence and not by experiment. And there is hardly enough evidence to be even evidential. Thus while most science moves in a sort of curve, being constantly corrected by new evidence, this science flies off into space in a straight line uncorrected by anything.

But the habit of forming conclusions, as they can really be formed in more fruitful fields, is so fixed in the Scientific mind that it cannot resist talking like this. It talks about the idea suggested by one scrap of bone as if it were something like the airplane which is constructed at last out of whole scrapheaps of scraps of metal. The trouble with the professor of the prehistoric is that he cannot scrap his scrap. The marvelous and triumphant airplane is made out of a hundred mistakes. The student of origins can only make one mistake and stick to it. We talk very truly of the patience of science; but in this department it would be truer to talk of the impatience of science. Owing to the difficulty above described, the theorist is in far too much of a hurry. We have a series of hypotheses so hasty that they may well be called fancies, and cannot in any case be further corrected by facts. The most empirical anthropologist is here as limited as an antiquary. He can only cling to a fragment of the past and has no way of increasing it for the future. He can only clutch his fragment of fact, almost as the primitive man clutched his fragment of flint. And indeed he does deal with it in much the same way and for much the same reason. It is his tool and his only tool. It is his weapon and his only weapon. He often wields it with a fanaticism far in excess of anything shown by men of science when they can collect more facts from experience and even add new facts by experiment. Sometimes the professor with his bone becomes almost as dangerous as a dog with his bone. And the dog at least does not deduce a theory from it, proving that mankind is going to the dogs-or that it came from them. For instance, I have pointed out the difficulty of keeping a monkey and watching it evolve into a man. Experimental evidence of such an evolution being impossible, the professor is not content to say (as most of us would be ready to say) that such an evolution is likely enough anyhow. He produces his little bone, or little collection of bones, and deduces the most marvelous things from it. He found in Java a piece of a skull, seeming by its contour to be smaller than the human. Somewhere near it he found an upright thigh-bone and in the same scattered fashion some teeth that were not human. If they all form part of one creature, which is doubtful, our conception of the creature would be almost equally doubtful. But the effect on popular science was to produce a complete and even complex figure, finished down to the last details of hair and habits. He was given a name as if he were an ordinary historical character. People talked of Pithecanthropus as of Pitt or Fox or Napoleon. Popular histories published portraits of ‘him like the portraits of Charles the First and George the Fourth. A detailed drawing was reproduced, carefully shaded, to show that the very hairs of his head were all numbered. No uninformed person looking at its carefully lined face and wistful eyes would imagine for a moment that this was the portrait of a thigh bone; or of a few teeth and a fragment of a cranium. In the same way people talked about him as if he were an individual whose influence and character were familiar to us all. I have just read a story in a magazine about Java and how modern white inhabitants of that island are prevailed on to misbehave themselves by the personal influence of poor old Pithecanthropus. That the modern inhabitants of Java misbehave themselves I can very readily believe; but I do not imagine that they need any encouragement from the discovery of a few highly doubtful bones. Anyhow, those bones are far too few and fragmentary and dubious to fill up the whole of the vast void that does in reason and in reality lie between man and his bestial ancestors, if they were his ancestors. On the assumption of that evolutionary connection (a connection which I am not in the least concerned to deny), the really arresting and remarkable fact is the comparative absence of any such remains recording that connection at that point. The sincerity of Darwin really admitted this; and that is how we came to use such a term as the Missing Link. But the dogmatism of Darwinian has been too strong for agnosticism of Darwin; and men have fallen into turning this entirely negative term into a positive image. They talk of searching for the habits and habitat of the Missing Link; as if one were to talk of being on friendly terms with the gap in a narrative or the hole in an argument, of taking a walk with a nonsequitur or dining with an undistributed middle. In this sketch, therefore, of man in his relation to certain religious and historical problems, I shall waste no further space on these speculations on the nature of man before he became man. His body may have been evolved from the brutes; but we know nothing of any such transition that throws the smallest light upon his soul as it has shown itself in history.
Unfortunately the same school of writers pursue the same style of reasoning when they come to the first real evidence about the first real men. Strictly speaking of course we know nothing about prehistoric man, for the simple reason that he was prehistoric. The history of the prehistoric man is a very obvious contradiction in terms. It is the sort of unreason in which only rationalists are allowed to indulge. If a parson had casually observed that the Flood was antediluvian, it is possible that be might be a little chaffed about his logic. If a bishop were to say that Adam was Pre-Adamite, we might think it a little odd. But we are not supposed to notice such verbal trifles when skeptical historians talk of the part of history that is prehistoric. The truth is that they are using the terms historic and prehistoric without any clear test or definition in their minds. What they mean is that there are traces of human lives before the beginning of human stories; and in that sense we do at least know that humanity was before history.

Human civilization is older than human records. That is the sane way of stating our relations to these remote things. Humanity has left examples of its other arts earlier than the art of writing; or at least of any writing that we can read. But it is certain that the primitive arts were arts; and it is in every way probable that the primitive civilizations were civilizations. The man left a picture of the reindeer, but he did not leave a narrative of how he hunted the reindeer; and therefore what we say of him is hypothesis and not history, But the art he did practice was quite artistic; his drawing was quite intelligent and there is no reason to doubt that his story of the hunt would be quite intelligent, only if it exists it is not intelligible. In short, the prehistoric period need not mean the primitive period, in the sense of the barbaric or bestial period. It does not mean the time before civilization or the time before arts and crafts. It simply means the time before any connected narratives that we can read. This does indeed make all the practical difference between remembrance and forgetfulness; but it is perfectly possible that there were all sorts of forgotten forms of civilization, as well as all sorts of forgotten forms of barbarism. And in any case everything indicated that many of these forgotten or half-forgotten social stages were much more civilized and much less barbaric than is vulgarly imagined today. But even about these unwritten histories of humanity, when humanity was quite certainly human, we can only conjecture with the greatest doubt and caution. And unfortunately doubt and caution are the last things commonly encouraged by the loose evolutionism of current culture. For that culture is full of curiosity; and the one thing that it cannot endure is the agony of agnosticism. It was in the Darwinian age that the word first became known and the thing first became impossible.

It is necessary to say plainly that all this ignorance is simply covered by impudence. Statements are made so plainly and positively that men have hardly the moral courage to pause upon them and find that they are without support. The other day a scientific summary of the state of a prehistoric tribe began confidently with the words ‘They wore no clothes! Not one reader in a hundred probably stopped to ask himself how we should come to know whether clothes had once been worn by people of whom everything has perished except a few chips of bone and stone. It was doubtless hoped that we should find a stone hat as well as a stone hatchet. It was evidently anticipated that we might discover an everlasting pair of trousers of the same substance as the everlasting rock. But to persons of a less sanguine temperament it will be immediately apparent that people might wear simple garments, or even highly ornamental garments, without leaving any more traces of them than these people have left. The plaiting of rushes and grasses, for instance, might have become more and more elaborate without in the least becoming more eternal. One civilisation might specialize in things that happen to be perishable, like weaving and embroidering, and not in things that happen to be more permanent, like architecture and sculpture. There have been plenty of examples of such specialist societies. A man of the future finding the ruins of our factory machinery might as fairly say that we were acquainted with iron and with no other substance; and announce the discovery that the proprietor and manager of the factory undoubtedly walked about naked-or possibly wore iron hats and trousers. It is not contended here that these primitive men did wear clothes any more than they did weave rushes; but merely that we have not enough evidence to know whether they did or not. But it may be worth while to look back for a moment at some of the very few things that we do know and that they did do. If we consider them, we shall certainly not find them inconsistent with such ideas as dress and decoration. We do not know whether they decorated themselves; but we do know that they decorated other things. We do not know whether they had embroideries, and if they had the embroideries could not be expected to have remained. But we do know that they did have pictures; and the pictures have remained. And there remains with them as already suggested the testimony to something that is absolute and unique; that belongs to man and to nothing else except man; that is a difference of kind and not a difference of degree. A monkey does not draw clumsily and a man cleverly; a-monkey does not begin the art of representation and a man carry it to perfection. A monkey does not do it at all; he does not begin to do it at all; he does not begin to begin to do it at all. A line of some kind is crossed before the first faint line can begin.

Another distinguished writer, again, in commenting on the cave drawings attributed to the Neolithic men of the reindeer period, said that none of their pictures appeared to have any religious purpose; and he seemed almost to infer that they had no religion. I can hardly imagine a thinner thread of argument than this which reconstructs the very inmost moods of the prehistoric mind from the fact that somebody who has scrawled a few sketches on a rock, from what motive we do not know, for what purpose we do not know, acting under what customs or conventions we do not know, may possibly have found it easier to draw reindeer than to draw religion. He may have drawn it because it was his religious symbol. He may have drawn it because it was not his religious symbol. He may have drawn anything except his religious symbol, He may have drawn his real religious symbol somewhere else; or it may have been deliberately destroyed when it was drawn. He may have done or not done half a million things; but in any case it is an amazing leap of logic to infer that he had no religious symbol, or even to infer from his having no religious symbol that he had no religion. Now this particular case happens to illustrate the insecurity of these guesses very clearly. For a little while afterwards, people discovered not only paintings but sculptures of animals in the caves. Some of these were said to be damaged with dints or holes supposed to be the marks of arrows; and the damaged images were conjectured to be the remains of some magic rite of killing the beasts in effigy; while the undamaged images were explained in connection with another magic rite invoking fertility upon the herds. Here again there is something faintly humorous about the scientific habit of having it both ways. If the image is damaged it proves one superstition and if it is undamaged it proves another. Here again there is a rather reckless jumping to conclusions; it has hardly occurred to the speculators that a crowd of hunters imprisoned in winter in a cave might conceivably have aimed at a mark for fun, as a sort of primitive parlor game. But in any case, if it was done out of superstition, what has become of the thesis that it had nothing to do with religion? The truth is that all this guesswork has nothing to do with anything. It is not half such a good parlor game as shooting arrows at a carved reindeer for it is shooting them into the air.

Such speculators rather tend to forget, for instance, that men in the modern world also sometimes make marks in caves. When a crowd of trippers is conducted through the labyrinth of the Marvelous Grotto or the Magic Stalactite Cavern, it has been observed that hieroglyphics spring into sight where they have passed; initials and inscriptions which the learned refuse to refer to any remote date. But the time will come when these inscriptions will really be of remote date. And if the professors of the future are anything like the professors of the present, they will be able to deduce a vast number of very vivid and interesting things from these cave writings of the twentieth century. If I know anything about the breed, and if they have not fallen away from the full-blooded
