The first language of mankind, the most universal and vivid, in a word the only language man needed, before he had occasion to exert his eloquence to persuade assembled multitudes, was the simple cry of nature
But as this was excited only by a sort of instinct on urgent occasions, to implore assistance in case of danger, or relief in case of suffering, it could be of little use in the ordinary course of life, in which more moderate feelings prevail. When the ideas of men began to expand and multiply, and closer communication took place among them, they strove to invent more numerous signs and a more copious language. They multiplied the inflections of the voice, and added gestures, which are in their own nature more expressive, and depend less for their meaning on a prior determination. Visible and movable objects were therefore expressed by gestures, and audible ones by imitative sounds: but, as hardly anything can be indicated by gestures, except objects actually present or easily described, and visible actions; as they are not universally useful-for darkness or the interposition of a material object destroys their efficacy-and as besides they rather request than secure our attention; men at length bethought themselves of substituting for them the articulate sounds of the voice, which, without bearing the same relation to any particular ideas, are better calculated to express them all, as conventional signs. Such an institution could only be made by common consent, and must have been effected in a manner not very easy for men whose gross organs had not been accustomed to any such exercise. It is also in itself still more difficult to conceive, since such a common agreement must have had motives, and speech seems to have been highly necessary to establish the use of it.
Every object at first received a particular name without regard to genus or species, which these primitive originators were not in a position to distinguish; every individual presented itself to their minds in isolation, as they are in the picture of nature
It is reasonable to suppose that the words first made use of by mankind had a much more extensive signification than those used in languages already formed, and that ignorant as they were of the division of discourse into its constituent parts, they at first gave every single word the sense of a whole proposition. When they began to distinguish subject and attribute, and noun and verb, which was itself no common effort of genius, substantives were at first only so many proper names; the present infinitive was the only tense of verbs; and the very idea of adjectives must have been developed with great difficulty; for every adjective is an abstract idea, and abstractions are painful and unnatural operations.
If one oak was called A, another was called B; for the primitive idea of two things is that they are not the same, and it often takes a long time for what they have in common to be seen: so that, the narrower the limits of their knowledge of things, the more copious their dictionary must have been. The difficulty of using such a vocabulary could not be easily removed; for, to arrange beings under common and generic denominations, it became necessary to know their distinguishing properties: the need arose for observation and definition, that is to say, for natural history and metaphysics of a far more developed kind than men can at that time have possessed.
Add to this, that general ideas cannot be introduced into the mind without the assistance of words, nor can the understanding seize them except by means of propositions. This is one of the reasons why animals cannot form such ideas, or ever acquire that capacity for self-improvement which depends on them. When a monkey goes from one nut to another, are we to conceive that he entertains any general idea of that kind of fruit, and compares its archetype with the two individual nuts? Assuredly he does not; but the sight of one of these nuts recalls to his memory the sensations which he received from the other, and his eyes, being modified after a certain manner, give information to the palate of the modification it is about to receive. If you endeavour to trace in your mind the image of a tree in general, you never attain to your end. In spite of all you can do, you will have to see it as great or little, bare or leafy, light or dark, and were you capable of seeing nothing in it but what is common to all trees, it would no longer be like a tree at all. Purely abstract beings are perceivable in the same manner, or are only conceivable by the help of language. The definition of a triangle alone gives you a true idea of it: the moment you imagine a http://maxloan.org/payday-loans-or/ triangle in your mind, it is some particular triangle and not another, and you cannot avoid giving it sensible lines and a coloured area. We must then make use of propositions and of language in order to form general ideas. For no sooner does the imagination cease to operate than the understanding proceeds only by the help of words. If then the first inventors of speech could give names only to ideas they already had, it follows that the first substantives could be nothing more than proper names.
