The philosophers, who have examined the foundations of society, have, every one of them, perceived the necessity of tracing it back to a state of nature, but not one of them has ever arrived there. Some of them have not scrupled to attribute to man in that state the ideas of justice and injustice, without troubling their heads to prove, that he really must have had such ideas, or even that such ideas were useful to him: others have spoken of the natural right of every man to keep what belongs to him, without letting us know what they meant by the word belong; others, without further ceremony ascribing to the strongest an authority over the weakest, have immediately struck out government, without thinking of the time requisite for men to form any notion of the things signified by the words authority and government. All of them, in fine, constantly harping on wants, avidity, oppression, desires and pride, have transferred to the state of nature ideas picked up in the bosom of society. In speaking of savages they described citizens. Nay, few of our own writers seem to have so much as doubted, that a state of nature did once actually exist; though it plainly appears by Sacred History, that even the first man, immediately furnished as he was by God himself with both instructions and precepts, never lived in that state, and that, if we give to the books of Moses that credit which every Christian philosopher ought to give to them, we must deny that, even before the deluge, such a state ever existed among men, unless they fell into it by some extraordinary event: a paradox very difficult to maintain, and altogether impossible to prove. Let us begin therefore, by laying aside facts, for they do not affect the question. The researches, in which we may engage on this occasion, are not to be taken for historical truths, but merely as hypothetical and conditional reasonings, fitter to illustrate the nature of things, than to show their true origin, like those systems, which our naturalists daily make of the formation of the world. Religion commands us to believe, that men, having been drawn by God himself out of a state of nature, are unequal, because it is his pleasure they should be so; but religion does not forbid us to draw conjectures solely from the nature of man, considered in itself, and from that of the beings which surround him, concerning the fate of mankind, had they been left to themselves. This is then the question I am to answer, the question I propose to examine in the present discourse. As mankind in general have an interest in my subject, I shall endeavour to use a language suitable to all nations; or rather, forgetting the circumstances of time and place in order to think of nothing but the men I speak to, I shall suppose myself in the Lyceum of Athens, repeating the lessons of my masters before the Platos and the Xenocrates of that famous seat of philosophy as my judges, and in presence of the whole human species as my audience.
