Savage man, left by nature solely to the direction of instinct, or rather indemnified for what he may lack by faculties capable at first of supplying its place, and afterwards of raising him much above it, must accordingly begin with purely animal functions: thus seeing and feeling must be his first condition, which would be common to him and all other animals. To will, and not to will, to desire and to fear, must be the first, and almost the only operations of his soul, till new circumstances occasion new developments of his faculties.

Whatever moralists may hold, the human understanding is greatly indebted to the passions, which, it is universally allowed, are also much indebted to the understanding. It is by the activity of the passions that pur reason is improved; for we desire knowledge only because we wish to enjoy; and it is impossible to conceive any reason why a person who has neither fears nor desires should give himself the trouble of reasoning. The passions, again, originate in our wants, and their progress depends on that of our knowledge; for we cannot desire or fear anything, except from the idea we have of it, or from the simple impulse of nature. Now savage man, being destitute of every species of intelligence, can have no passions save those of the latter kind: his desires never go beyond his physical wants. The only goods he recognises in the universe are food, a female, and sleep: the only evils he fears are pain and hunger. I say pain, and not death: for no animal can know what it is to die; the knowledge of death and its terrors being one of the first acquisitions made by man in departing from an animal state.

It would be easy, were it necessary, to support this opinion by facts, and to show that, in all the nations of the world, the progress of the understanding has been exactly proportionate to the wants which the peoples had received from nature, or been subjected to by circumstances, and in consequence to the passions that induced them to provide for those necessities. I might instance the arts, rising up in Egypt and expanding with the inundation of the Nile. I might follow their progress into Greece, where they took root afresh, grew up and towered to the skies, among the rocks and sands of Attica, without being able to germinate on the fertile banks of the Eurotas: I might observe that in general, the people of the North are more industrious than those of the South, because they cannot get on so well without being so: as if nature wanted to equalise matters by giving their understandings the fertility she had refused to their soil.

But who does not see, without recurring to the uncertain testimony of history, that everything seems to remove from savage man both the temptation and the means of changing his condition? His imagination paints no pictures; his heart makes no demands on him. His few wants are so readily supplied, and he is so far from having the knowledge which is needful to make him want more, that he can have neither foresight nor curiosity. The face of nature becomes indifferent to him as it grows familiar. He sees in it always the same order, the same successions: he has not understanding enough to wonder at the greatest miracles; nor is it in his mind that we can expect to find that philosophy man needs, if he is to know how to notice for once what he sees every day. His soul, which nothing disturbs, is wholly wrapped up in the feeling of its present existence, without any idea of the future, however near at hand; while his projects, as limited as his views, hardly extend to the close of day. Such, even at present, is the extent of the native Caribean's foresight: he will improvidently sell you his cotton-bed in the morning, and come crying in the evening to buy it again, not having foreseen he would want it again the next night.

The more we reflect on this subject, the greater appears the distance between pure sensation and the most simple knowledge: it is impossible indeed to conceive how a man, by his own powers alone, without the aid of communication and the spur of necessity, could have bridged so great a gap. How many ages may have elapsed before mankind were in a position to behold any other Are than that of the heavens. What a multiplicity of chances must have happened to teach them the commonest uses of that element! How often must they have let it out before they acquired the art of reproducing it? and how often may not such a secret have died with him who had discovered it? What shall we say of agriculture, an art which requires so much labour and foresight, which is so dependent on others that it is plain it could only be practised in a society which had at least begun, and which does not serve so much to draw the means of subsistence from the earth —for these it would produce of itself—but to compel it to produce what is most to our taste? But let us suppose that men had so multiplied that the natural produce of the earth was no longer sufficient for their support; a supposition, by the way, which would prove such a life to be very advantageous for the human race; let us suppose that, without forges or workshops, the instruments of husbandry had dropped from the sky into the hands of savages; that they had overcome their natural aversion to continual labour; that they had learnt so much foresight for their needs; that they had divined how to cultivate the earth, to sow grain and plant trees; that they had discovered the arts of grinding corn, and of setting the grape to ferment—all being things that must have been taught them by the gods, since it is not to be conceived how they could discover them for themselves—yet after all this, what man among them would be so absurd as to take the trouble of cultivating a field, which might be stripped of its crop by the first comer, man or beast, that might take a liking to it; and how should each of them resolve to pass his life in wearisome labour, when, the more necessary to him the reward of his labour might be, the surer he would be of not getting it? In a word, how could such a situation induce men to cultivate the earth, till it was regularly parcelled out among them; that is to say, till the state of nature had been abolished?

Were we to suppose savage man as trained in the art of thinking as philosophers make him; were we, like them, to suppose him a very philosopher capable of investigating the sublimest truths, and of forming, by highly abstract chains of reasoning, maxims of reason and justice, deduced from the love of order in general, or the known will of his Creator; in a word, were we to suppose him as intelligent and enlightened, as he must have been, and is in fact found to have been, dull and stupid, what advantage Would accrue to the species, from all such metaphysics, which could not be communicated by one to another, but must end with him who made them? What progress could be made by mankind, while dispersed in the woods among other animals? and how far could men improve or mutually enlighten one another, when, having no fixed habitation, and no need of one another's assistance, the same persons hardly met twice in their lives, and perhaps then, without knowing one another or speaking together?

Let it be considered how many ideas we owe to the use of speech; how far grammar exercises the understanding and facilitates its operations. Let us reflect on the inconceivable pains and the infinite space of time that the first invention of languages must have cost. To these reflections add what preceded, and then judge how many thousand ages must have elapsed in the successive development in the human mind of those operations of which it is capable.

I shall here take the liberty for a moment, of considering the difficulties of the origin of languages, on which subject I might content myself with a simple repetition of the Abbé Condillac's investigations, as they fully confirm my system, and perhaps even first suggested it. But it is plain, from the manner in which this philosopher solves the difficulties he himself raises, concerning the origin of arbitrary signs, that he assumes what I question, viz. that a kind of society, must already have existed among the first inventors of language. While I refer, therefore, to his observations on this head, I think it right to give my own, in order to exhibit the same difficulties in a light adapted to my subject. The first which presents itself is to conceive how language can have become necessary; for as there was no communication among men and no need for any, we can neither conceive the necessity of this invention, nor the possibility of it, if it was not somehow indispensable. I might affirm, with many others, that languages arose in the domestic intercourse between parents and their children. But this expedient would not obviate the difficulty, and would besides involve the blunder made by those who, in reasoning on the state of nature, always import into it ideas gathered in a state of society. Thus they constantly consider families as living together under one roof, and the individuals of each as observing among themselves a union as intimate and permanent as that which exists among us, where so many common interests unite them: whereas, in this primitive state, men had neither houses, nor huts, nor any kind of property whatever; every one lived where he could, seldom for more than a single night; the sexes united without design, as accident, opportunity or inclination brought them together, nor had they any great need of words to communicate their designs to each other; and they parted with the same indifference. The mother gave suck to her children at first for her own sake; and afterwards, when habit had made them dear, for theirs: but as soon as they were strong enough to go in search of their own food, they forsook her of their own accord; and, as they had hardly any other method of not losing one another than that of remaining continually within sight, they soon became quite incapable of recognising one another when they happened to meet again. It is farther to be observed that the child, having all his wants to explain, and of course more to say to his mother than the mother could have to say to him, must have borne the brunt of the task of invention, and the language he used would be of his own device, so that the number of languages would be equal to that of the individuals speaking them, and the variety would be increased by the vagabond and roving life they led, which would not give time for any idiom to become constant. For to say that the mother dictated to her child the words he was to use in asking her for one thing or another, is an explanation of how languages already formed are taught, but by no means explains how languages were originally formed.

We will suppose, however, that this first difficulty is obviated. Let us for a moment then take ourselves as being on this side of the vast space which must lie between a pure state of nature and that in which languages had become necessary, and, admitting their necessity, let us inquire how they could first be established. Here we have a new and worse difficulty to grapple with; for if men need speech to learn to think, they must have stood in much greater need of the art of thinking, to be able to invent that of speaking. And though we might conceive how the articulate sounds of the voice came to be taken as the conventional interpreters of our ideas, it would still remain for us to inquire what could have been the interpreters of this convention for those ideas, which, answering to no sensible objects, could not be indicated either by gesture or voice; so that we can hardly form any tolerable conjectures about the origin of this art of communicating our thoughts and establishing a correspondence between minds: an art so sublime, that far distant as it is from its origin, philosophers still behold it at such an immeasurable distance from perfection, that there is none rash enough to affirm it will ever reach it, even though the revolutions time necessarily produces were suspended in its favour, though prejudice should be banished from our academies or condemned to silence, and those learned societies should devote themselves uninterruptedly for whole ages to this thorny question.

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.
