Everything now begins to wear a new aspect. Those who heretofore wandered through the woods, by taking to a more settled way of life, gradually flock together, coalesce into several separate bodies, and at length form in every country distinct nations, united in character and manners, not by any laws or regulations, but by an uniform manner of life, a sameness of provisions, and the common influence of the climate. A permanent neighborhood must at last infallibly create some connection between different families. The transitory commerce required by nature soon produced, among the youth of both sexes living in contiguous cabins, another kind of commerce, which besides being equally agreeable is rendered more durable by mutual intercourse. Men begin to consider different objects, and to make comparisons; they insensibly acquire ideas of merit and beauty, and these soon produce sentiments of preference. By seeing each other often they contract a habit, which makes it painful not to see each other always. Tender and agreeable sentiments steal into the soul, and are by the smallest opposition wound up into the most impetuous fury: Jealousy kindles with love; discord triumphs; and the gentlest of passions requires sacrifices of human blood to appease it. In proportion as ideas and sentiments succeed each other, and the head and the heart exercise themselves, men continue to shake off their original wildness, and their connections become more intimate and extensive. They now begin to assemble round a great tree: singing and dancing, the genuine offspring of love and leisure, become the amusement or rather the occupation of the men and women, free from care, thus gathered together. Every one begins to survey the rest, and wishes to be surveyed himself; and public esteem acquires a value. He who sings or dances best; the handsomest, the strongest, the most dexterous, the most eloquent, comes to be the most respected: this was the first step towards inequality, and at the same time towards vice. From these first preferences there proceeded on one side vanity and contempt, on the other envy and shame; and the fermentation raised by these new leavens at length produced combinations fatal to happiness and innocence.
