Against this Professor Max Müller contends that we can know nothing of what goes on in the mind of any lower animal, inasmuch as we are not lower animals ourselves. “We can imagine anything we like about what passes in the mind of an animal,” he writes, “we can know absolutely nothing.” [{234}] It is something to have it in evidence that he conceives animals as having a mind at all, but it is not easy to see how they can be supposed to have a mind, without being able to acquire ideas, and having acquired, to read, mark, learn and inwardly digest them. Surely the mistake of requiring too much evidence is hardly less great than that of being contented with too little. We, too, are animals, and can no more refuse to infer reason from certain visible actions in their case than we can in our own. If Professor Max Müller’s plea were allowed, we should have to deny our right to infer confidently what passes in the mind of anyone not ourselves, inasmuch as we are not that person. We never, indeed, can obtain irrefragable certainty about this or any other matter, but we can be sure enough in many cases to warrant our staking all that is most precious to us on the soundness of our opinion. Moreover, if the Professor denies our right to infer that animals reason, on the ground that we are not animals enough ourselves to be able to form an opinion, with what right does he infer so confidently himself that they do not reason? And how, if they present every one of those appearances which we are accustomed to connect with the communication of an idea from one mind to another, can we deny that they have a language of their own, though it is one which in most cases we can neither speak nor understand? How can we say that a sentinel rook, when it sees a man with a gun and warns the other rooks by a concerted note which they all show that they understand by immediately taking flight, should not be credited both with reason and the germs of language?
After all, a professor, whether of philology, psychology, biology, or any other ology, is hardly the kind of person to whom we should appeal on such an elementary question as that of animal intelligence and language. We might as well ask a botanist to tell us whether grass grows, or a meteorologist to tell us if it has left off raining. If it is necessary to appeal to anyone, I should prefer the opinion of an intelligent gamekeeper to that of any professor, however learned. The keepers, again, at the Zoological Gardens, have exceptional opportunities for studying the minds of animals—modified, indeed, by captivity, but still minds of animals. Grooms, again, and dog-fanciers, are to the full as able to form an intelligent opinion on the reason and language of animals as any University Professor, and so are cat’s-meat men. I have repeatedly asked gamekeepers and keepers at the Zoological Gardens whether animals could reason and converse with one another, and have always found myself regarded somewhat contemptuously for having even asked the question. I once said to a friend, in the hearing of a keeper at the Zoological Gardens, that the penguin was very stupid. The man was furious, and jumped upon me at once. “He’s not stupid at all,” said he; “he’s very intelligent.”
Who has not seen a cat, when it wishes to go out, raise its fore paws on to the handle of the door, or as near as it can get, and look round, evidently asking someone to turn it for her? Is it reasonable to deny that a reasoning process is going on in the cat’s mind, whereby she connects her wish with the steps necessary for its fulfilment, and also with certain invariable symbols which she knows her master or mistress will interpret? Once, in company with a friend, I watched a cat playing with a house-fly in the window of a ground-floor room. We were in the street, while the cat was inside. When we came up to the window she gave us one searching look, and, having satisfied herself that we had nothing for her, went on with her game. She knew all about the glass in the window, and was sure we could do nothing to molest her, so she treated us with absolute contempt, never even looking at us again.
The game was this. She was to catch the fly and roll it round and round under her paw along the window-sill, but so gently as not to injure it nor prevent it from being able to fly again when she had done rolling it. It was very early spring, and flies were scarce, in fact there was not another in the whole window. She knew that if she crippled this one, it would not be able to amuse her further, and that she would not readily get another instead, and she liked the feel of it under her paw. It was soft and living, and the quivering of its wings tickled the ball of her foot in a manner that she found particularly grateful; so she rolled it gently along the whole length of the window-sill. It then became the fly’s turn. He was to get up and fly about in the window, so as to recover himself a little; then she was to catch him again, and roll him softly all along the window-sill, as she had done before.
It was plain that the cat knew the rules of her game perfectly well, and enjoyed it keenly. It was equally plain that the fly could not make head or tail of what it was all about. If it had been able to do so it would have gone to play in the upper part of the window, where the cat could not reach it. Perhaps it was always hoping to get through the glass, and escape that way; anyhow, it kept pretty much to the same pane, no matter how often it was rolled. At last, however, the fly, for some reason or another, did not reappear on the pane, and the cat began looking everywhere to find it. Her annoyance when she failed to do so was extreme. It was not only that she had lost her fly, but that she could not conceive how she should have ever come to do so. Presently she noted a small knot in the woodwork of the sill, and it flashed upon her that she had accidentally killed the fly, and that this was its dead body. She tried to move it gently with her paw, but it was no use, and for the time she satisfied herself that the knot and the fly had nothing to do with one another. Every now and then, however, she returned to it as though it were the only thing she could think of, and she would try it again. She seemed to say she was certain there had been no knot there before—she must have seen it if there had been; and yet, the fly could hardly have got jammed so firmly into the wood. She was puzzled and irritated beyond measure, and kept looking in the same place again and again, just as we do when we have mislaid something. She was rapidly losing temper and dignity when suddenly we saw the fly reappear from under the cat’s stomach and make for the window-pane, at the very moment when the cat herself was exclaiming for the fiftieth time that she wondered where that stupid fly ever could have got to. No man who has been hunting twenty minutes for his spectacles could be more delighted when he suddenly finds them on his own forehead. “So that’s where you were,” we seemed to hear her say, as she proceeded to catch it, and again began rolling it very softly without hurting it, under her paw.
My friend and I both noticed that the cat, in spite of her perplexity, never so much as hinted that we were the culprits. The question whether anything outside the window could do her good or harm had long since been settled by her in the negative, and she was not going to reopen it; she simply cut us dead, and though her annoyance was so great that she was manifestly ready to lay the blame on anybody or anything with or without reason, and though she must have perfectly well known that we were watching the whole affair with amusement, she never either asked us if we had happened to see such a thing as a fly go down our way lately, or accused us of having taken it from her—both of which ideas she would, I am confident, have been very well able to convey to us if she had been so minded.
Now what are thought and reason if the processes that were going through this cat’s mind were not both one and the other? It would be childish to suppose that the cat thought in words of its own, or in anything like words. Its thinking was probably conducted through the instrumentality of a series of mental images. We so habitually think in words ourselves that we find it difficult to realize thought without words at all; our difficulty, however, in imagining the particular manner in which the cat thinks has nothing to do with the matter. We must answer the question whether she thinks or no, not according to our own ease or difficulty in understanding the particular manner of her thinking, but according as her action does or does not appear to be of the same character as other action that we commonly call thoughtful. To say that the cat is not intelligent, merely on the ground that we cannot ourselves fathom her intelligence—this, as I have elsewhere said, is to make intelligence mean the power of being understood, rather than the power of understanding. This nevertheless is what, for all our boasted intelligence, we generally do. The more we can understand an animal’s ways, the more intelligent we call it, and the less we can understand these, the more stupid do we declare it to be. As for plants—whose punctuality and attention to all the details and routine of their somewhat restricted lines of business is as obvious as it is beyond all praise—we understand the working of their minds so little that by common consent we declare them to have no intelligence at all.
Before concluding I should wish to deal a little more fully with Professor Max Müller’s contention that there can be no reason without language, and no language without reason. Surely when two practised pugilists are fighting, parrying each other’s blows, and watching keenly for an unguarded point, they are thinking and reasoning very subtly the whole time, without doing so in words. The machination of their thoughts, as well as its expression, is actual—I mean, effectuated and expressed by action and deed, not words. They are unaware of any logical sequence of thought that they could follow in words as passing through their minds at all. They may perhaps think consciously in words now and again, but such thought will be intermittent, and the main part of the fighting will be done without any internal concomitance of articulated phrases. Yet we cannot doubt that their action, however much we may disapprove of it, is guided by intelligence and reason; nor should we doubt that a reasoning process of the same character goes on in the minds of two dogs or fighting-cocks when they are striving to master their opponents.
Do we think in words, again, when we wind up our watches, put on our clothes, or eat our breakfasts? If we do, it is generally about something else. We do these things almost as much without the help of words as we wink or yawn, or perform any of those other actions that we call reflex, as it would almost seem because they are done without reflection. They are not, however, the less reasonable because wordless.
Even when we think we are thinking in words, we do so only in half measure. A running accompaniment of words no doubt frequently attends our thoughts; but, unless we are writing or speaking, this accompaniment is of the vaguest and most fitful kind, as we often find out when we try to write down or say what we are thinking about, though we have a fairly definite notion of it, or fancy that we have one, all the time. The thought is not steadily and coherently governed by and moulded in words, nor does it steadily govern them. Words and thought interact upon and help one another, as any other mechanical appliances interact on and help the invention that first hit upon them; but reason or thought, for the most part, flies along over the heads of words, working its own mysterious way in paths that are beyond our ken, though whether some of our departmental personalities are as unconscious of what is passing, as that central government is which we alone dub with the name of “we” or “us,” is a point on which I will not now touch.
