Taught by experience that the love of well-being is the sole motive of human actions, he found himself in a position to distinguish the few cases, in which mutual interest might justify him in relying upon the assistance of his fellows; and also the still fewer cases in which a conflict of interests might give cause to suspect them. In the former case, he joined in the same herd with them, or at most in some kind of loose association, that laid no restraint on its members, and lasted no longer than the transitory occasion that formed it. In the latter case, every one sought his own private advantage, either by open force, if he thought himself strong enough, or by address and cunning, if he felt himself the weaker.
In this manner, men may have insensibly acquired some gross ideas of mutual undertakings, and of the advantages of fulfilling them: that is, just so far as their present and apparent interest was concerned: for they were perfect strangers to foresight, and were so far from troubling themselves about the distant future, that they hardly thought of the morrow. If a deer was to be taken, every one saw that, in order to succeed, he must abide faithfully by his post: but if a hare happened to come within the reach of any one of them, it is not to be doubted that he pursued it without scruple, and, having seized his prey, cared very little, if by so doing he caused his companions to miss theirs.
It is easy to understand that such intercourse would not require a language much more refined than that of rooks or monkeys, who associate together for much the same, purpose. Inarticulate cries, plenty of gestures and some imitative sounds, must have been for a long time the universal language; and by the addition, in every country, of some conventional articulate sounds (of which, as I have already intimated, the first institution is not too easy to explain) particular languages were produced; but these were rude and imperfect, and nearly such as now to be found among some savage nations.
Hurried on by the rapidity of time, by the abundance of things I have to say, and by the almost insensible progress of things in their beginnings, I pass over in an instant a multitude of ages; for the slower the events were in their succession, the more rapidly may they be described.
These first advances enabled men to make others with greater rapidity. In proportion as they grew enlightened, they grew industrious. They ceased to fall asleep under the first tree, or in the first cave that afforded them shelter; they invented several kinds of implements of hard and sharp stones, which they used to dig up the earth, and to cut wood; they then made huts out of branches, and afterwards learnt to plaster them over with mud and clay. This was the epoch of a first revolution, which established and distinguished families, and introduced a kind of property, in itself the source of a thousand quarrels and conflicts. As, however, the strongest were probably the first to build themselves huts which they felt themselves able to defend, it may be concluded that the weak found it much easier and safer to imitate, than to attempt to dislodge them: and of those who were once provided with huts, none could have any inducement to appropriate that of his neighbour; not indeed so much because it did not belong to him, as because it could be of no use, and he could not make himself master of it without exposing himself to a desperate battle with the family which occupied it.
The first expansions of the human heart were the effects of a novel situation, which united husbands and wives, fathers and children, under one roof. The habit of living together soon gave rise to the finest feelings known to humanity, conjugal love and paternal affection. Every family became a little society, the more united because liberty—and reciprocal attachment were the only bonds of its union. The sexes, whose manner of life had been hitherto the same, began now to adopt different ways of living. The women became more sedentary, and accustomed themselves to mind the hut and their children, while the men went abroad in search of their common subsistence. From living a softer life, both sexes also began to lose something of their strength and ferocity: but, if individuals became to some extent less able to encounter wild beasts separately, they found it, on the other hand, easier to assemble and resist in common.
The simplicity and solitude of man's life in this new condition, the paucity of his wants, and the implements he had invented to satisfy them, left him a great deal of leisure, which he employed to furnish himself with many conveniences unknown to his fathers: and this was the first yoke he inadvertently imposed on himself, and the first source of the evils he prepared for his descendants. For, besides continuing thus to enervate both body and mind, these conveniences lost with use almost all their power to please, and even degenerated into real needs, till the want of them became far more disagreeable than the possession of them had been pleasant. Men would have been unhappy at the loss of them, though the possession did not make them happy.
We can here see a little better how the use of speech became established, and insensibly improved in each family, and we may form a conjecture also concerning the manner in which various causes may have extended and accelerated the progress of language, by making it more and more necessary. Floods or earthquakes surrounded inhabited districts with precipices or waters: revolutions of the globe tore off portions from the continent, and made them islands. It is readily seen that among men thus collected and compelled to live together, a common idiom must have arisen much more easily than among those who still wandered through the forests of the continent. Thus it is very possible that after their first essays in navigation the islanders brought over the use of speech to the continent: and it is at least very probable that communities and languages were first established in islands, and even came to perfection there before they were known on the mainland.
Everything now begins to change its aspect. Men, who have up to now been roving in the woods, by taking to a more settled manner of life, come gradually together, form separate bodies, and at length in every country arises a distinct nation, united in character and manners, not by regulations or laws, but by uniformity of life and food, and the common influence of climate. Permanent neighbourhood could not fail to produce, in time, some connection between different families. Among young people of opposite sexes, living in neighbouring huts, the transient commerce required by nature soon led, through mutual intercourse, to another kind not less agreeable, and more permanent. Men began now to take the difference between objects into account, and to make comparisons; they acquired imperceptibly the ideas of beauty and merit, which soon gave rise to feelings of preference. In consequence of seeing each other often, they could not do without seeing each other constantly. A tender and pleasant feeling insinuated itself into their souls, and the least opposition turned it into an impetuous fury: with love arose jealousy; discord triumphed, and human blood was sacrificed to the gentlest of all passions.
As ideas and feelings succeeded one another, and heart and head were brought into play, men continued to lay aside their original wildness; their private connections became every day more intimate as their limits extended. They accustomed themselves to assemble before their huts round a large tree; singing and dancing, the true offspring of love and leisure, became the amusement, or rather the occupation, of men and women thus assembled together with nothing else to do. Each one began to consider the rest, and to wish to be considered in turn; and thus a—value came to be attached to public esteem. Whoever sang or danced best, whoever was the handsomest, the strongest, the most dexterous, or the most eloquent, came to be of most consideration; and this was the first step towards inequality, and at the same time towards vice. From these first distinctions arose on the one side vanity and contempt and on the other shame and envy: and the fermentation caused by these new leavens ended by producing combinations fatal to innocence and happiness.
