In 1755 appeared the _Discourse on the Origin and Foundation of Inequality among Men_, which is the second of the works given in this volume. With this essay, Rousseau had unsuccessfully competed in 1753 for a second prize offered by the Academy of Dijon, and he now issued it prefaced by a long Dedication to the Republic of Geneva. In this work, which Voltaire, in thanking him for a presentation copy, termed his "second book against the human race," his style and his ideas have made a great advance; he is no longer content merely to push a single idea to extremes: while preserving the broad opposition between the state of nature and the state of society, which runs through all his work, he is concerned to present a rational justification of his views and to admit that a little at any rate may be said on the other side. Moreover, the idea of "nature" has already undergone a great development; it is no longer an empty opposition to the evils of society; it possesses a positive content. Thus half the _Discourse on Inequality_ is occupied by an imaginary description of the state of nature, in which man is shown with ideas limited within the narrowest range, with little need of his fellows, and little care beyond provision for the necessities of the moment. Rousseau declares explicitly that he does not suppose the "state of nature" ever to have existed: it is a pure "idea of reason," a working concept reached by abstraction from the "state of society." The "natural man," as opposed to "man's man," is man stripped of all that society confers upon him, a creature formed by a process of abstraction, and never intended for a historical portrait. The conclusion of the Discourse favours not this purely abstract being, but a state of savagery intermediate between the "natural" and the "social" conditions, in which men may preserve the simplicity and the advantages of nature and at the same time secure the rude comforts and assurances of early society. In one of the long notes appended to the Discourse, Rousseau further explains his position. He does not wish, he says, that modern corrupt society should return to a state of nature: corruption has gone too far for that; he only desires now that men should palliate, by wiser use of the fatal arts, the mistake of their introduction. He recognises society as inevitable and is already feeling his way towards a justification of it. The second Discourse represents a second stage in his political thought: the opposition between the state of nature and the state of society is still presented in naked contrast; but the picture of the former has already filled out, and it only remains for Rousseau to take a nearer view of the fundamental implications of the state of society for his thought to reach maturity.
