Among them, as in every society, a particular person would be more sensitive and intelligent than the rest. Suddenly, on some occasion of interest (at the approach of a wild beast, shall we say?), he first, they following him, utter a cry which resounds through the forest. The cry is almost or quite involuntary, and may be an imitation of the roar of the animal. Thus far we have not speech, but only the inarticulate expression of feeling or emotion in no respect differing from the cries of animals; for they too call to one another and are answered. But now suppose that some one at a distance not only hears the sound, but apprehends the meaning: or we may imagine that the cry is repeated to a member of the society who had been absent; the others act the scene over again when he returns home in the evening. And so the cry becomes a word. The hearer in turn gives back the word to the speaker, who is now aware that he has acquired a new power. Many thousand times he exercises this power; like a child learning to talk, he repeats the same cry again, and again he is answered; he tries experiments with a like result, and the speaker and the hearer rejoice together in their newly-discovered faculty. At first there would be few such cries, and little danger of mistaking or confusing them.
For the mind of primitive man had a narrow range of perceptions and feelings; his senses were microscopic; twenty or thirty sounds or gestures would be enough for him, nor would he have any difficulty in finding them.
Naturally he broke out into speech--like the young infant he laughed and babbled; but not until there were hearers as well as speakers did language begin. Not the interjection or the vocal imitation of the object, but the interjection or the vocal imitation of the object understood, is the first rudiment of human speech.
After a while the word gathers associations, and has an independent existence. The imitation of the lion's roar calls up the fears and hopes of the chase, which are excited by his appearance. In the moment of hearing the sound, without any appreciable interval, these and other latent experiences wake up in the mind of the hearer. Not only does he receive an impression, but he brings previous knowledge to bear upon that impression.
Necessarily the pictorial image becomes less vivid, while the association of the nature and habits of the animal is more distinctly perceived. The picture passes into a symbol, for there would be too many of them and they would crowd the mind; the vocal imitation, too, is always in process of being lost and being renewed, just as the picture is brought back again in the description of the poet. Words now can be used more freely because there are more of them. What was once an involuntary expression becomes voluntary. Not only can men utter a cry or call, but they can communicate and converse; they can not only use words, but they can even play with them. The word is separated both from the object and from the mind; and slowly nations and individuals attain to a fuller consciousness of themselves.
Parallel with this mental process the articulation of sounds is gradually becoming perfected. The finer sense detects the differences of them, and begins, first to agglomerate, then to distinguish them. Times, persons, places, relations of all kinds, are expressed by modifications of them.
The earliest parts of speech, as we may call them by anticipation, like the first utterances of children, probably partook of the nature of interjections and nouns; then came verbs; at length the whole sentence appeared, and rhythm and metre followed. Each stage in the progress of language was accompanied by some corresponding stage in the mind and civilisation of man. In time, when the family became a nation, the wild growth of dialects passed into a language. Then arose poetry and literature. We can hardly realize to ourselves how much with each improvement of language the powers of the human mind were enlarged; how the inner world took the place of outer; how the pictorial or symbolical or analogical word was refined into a notion; how language, fair and large and free, was at last complete.
So we may imagine the speech of man to have begun as with the cries of animals, or the stammering lips of children, and to have attained by degrees the perfection of Homer and Plato. Yet we are far from saying that this or any other theory of language is proved by facts. It is not difficult to form an hypothesis which by a series of imaginary transitions will bridge over the chasm which separates man from the animals.
Differences of kind may often be thus resolved into differences of degree.
But we must not assume that we have in this way discovered the true account of them. Through what struggles the harmonious use of the organs of speech was acquired; to what extent the conditions of human life were different; how far the genius of individuals may have contributed to the discovery of this as of the other arts, we cannot say: Only we seem to see that language is as much the creation of the ear as of the tongue, and the expression of a movement stirring the hearts not of one man only but of many, 'as the trees of the wood are stirred by the wind.' The theory is consistent or not inconsistent with our own mental experience, and throws some degree of light upon a dark corner of the human mind.
