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.
