(6) Thus far we have been endeavouring to strip off from language the false appearances in which grammar and philology, or the love of system generally, have clothed it. We have also sought to indicate the sources of our knowledge of it and the spirit in which we should approach it, we may now proceed to consider some of the principles or natural laws which have created or modified it.
I. The first and simplest of all the principles of language, common also to the animals, is imitation. The lion roars, the wolf howls in the solitude of the forest: they are answered by similar cries heard from a distance. The bird, too, mimics the voice of man and makes answer to him. Man tells to man the secret place in which he is hiding himself; he remembers and repeats the sound which he has heard. The love of imitation becomes a passion and an instinct to him. Primitive men learnt to speak from one another, like a child from its mother or nurse. They learnt of course a rudimentary, half-articulate language, the cry or song or speech which was the expression of what we now call human thoughts and feelings. We may still remark how much greater and more natural the exercise of the power is in the use of language than in any other process or action of the human mind.
II. Imitation provided the first material of language: but it was “without form and void.” During how many years or hundreds or thousands of years the imitative or half-articulate stage continued there is no possibility of determining. But we may reasonably conjecture that there was a time when the vocal utterance of man was intermediate between what we now call language and the cry of a bird or animal. Speech before language was a rudis indigestaque materies, not yet distributed into words and sentences, in which the cry of fear or joy mingled with more definite sounds recognized by custom as the expressions of things or events. It was the principle of analogy which introduced into this “indigesta moles” order and measure. It was Anaxagoras’ ὁμοῦ πάντα χρήματα, εἰτα νοῦς ἐλθὼν διεκόσμησε: the light of reason lighted up all things and at once began to arrange them. In every sentence, in every word and every termination of a word, this power of forming relations to one another was contained. There was a proportion of sound to sound, of meaning to meaning, of meaning to sound. The cases and numbers of nouns, the persons, tenses, numbers of verbs, were generally on the same or nearly the same pattern and had the same meaning. The sounds by which they were expressed were rough-hewn at first; after a while they grew more refined—the natural laws of euphony began to affect them. The rules of syntax are likewise based upon analogy. Time has an analogy with space, arithmetic with geometry. Not only in musical notes, but in the quantity, quality, accent, rhythm of human speech, trivial or serious, there is a law of proportion. As in things of beauty, as in all nature, in the composition as well as in the motion of all things, there is a similarity of relations by which they are held together.
It would be a mistake to suppose that the analogies of language are always uniform: there may be often a choice between several, and sometimes one and sometimes another will prevail. In Greek there are three declensions of nouns; the
