Rousseau's Emile, the greatest of all works on education, has already been issued in this series. In this volume are contained the most important of his political works. Of these the Social Contract, by far the most significant, is the latest in date. It represents the maturity of his thought, while the other works only illustrate his development. Born in 1712, he issued no work of importance till 1750; but he tells us, in the Confessions, that in 1743, when he was attached to the Embassy at Venice, he had already conceived the idea of a great work on Political Institutions, "which was to put the seal on his reputation." He seems, however, to have made little progress with this work, until in 1749 he happened to light on the announcement of a prize offered by the Academy of Dijon for an answer to the question, "Has the progress of the arts and sciences tended to the purification or to the corruption of morality?" His old ideas came thronging back, and sick at heart of the life he had been leading among the Paris lumières, he composed a violent and rhetorical diatribe against civilisation generally. In the following year, this work, having been awarded the prize by the Academy, was published by its author. His success was instantaneous; he became at once a famous man, the "lion" of Parisian literary circles. Refutations of his work were issued by professors, scribblers, outraged theologians and even by the King of Poland. Rousseau endeavoured to answer them all, and in the course of argument his thought developed. From 1750 to the publication of the Social Contract and Emile in 1762 he gradually evolved his views: in those twelve years he made his unique contribution to political thought.
The Discourse on the Arts and Sciences, the earliest of the works reproduced in this volume, is not in itself of very great importance. Rousseau has given his opinion of it in the Confessions. "Full of warmth and force, it is wholly without logic or order; of all my works it is the weakest in argument and the least harmonious. But whatever gifts a man may be born with, he cannot learn the art of writing in a moment." This criticism is just. The first Discourse neither is, nor attempts to be, a reasoned or a balanced production. It is the speech of an advocate, wholly one-sided and arbitrary, but so obviously and naively one-sided, that it is difficult for us to believe in its entire seriousness. At the most, it is only a rather brilliant but flimsy rhetorical effort, a sophistical improvisation, but not a serious contribution to thought. Yet it is certain that this declamation made Rousseau's name, and established his position as a great writer in Parisian circles. D'Alembert even devoted the preface of the Encyclopædia to a refutation. The plan of the first Discourse is essentially simple: it sets out from the badness, immorality and misery of modern nations, traces all these ills to the departure from a "natural" state, and then credits the progress of the arts and sciences with being the cause of that departure. In it, Rousseau is already in possession of his idea of "nature" as an ideal; but he has at present made no attempt to discriminate, in what is unnatural, between good and bad. He is merely using a single idea, putting it as strongly as he can, and neglecting all its limitations. The first Discourse is important not for any positive doctrine it contains, but as a key to the development of Rousseau's mind. Here we see him at the beginning of the long journey which was to lead on at last to the theory of the Social Contract.
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.
Rousseau is often blamed, by modern critics, for pursuing in the Discourses a method apparently that of history, but in reality wholly unhistorical. But it must be remembered that he himself lays no stress on the historical aspect of his work; he gives himself out as constructing a purely ideal picture, and not as depicting any actual stages in human history. The use of false historical concepts is characteristic of the seventeenth and eighteenth centuries, and Rousseau is more to be congratulated on having escaped from giving them too much importance than criticised for employing them at all.
It is doubtful whether the Discourse on Political Economy, first printed in the great Encyclopædia in 1755, was composed before or after the Discourse on Inequality. At first sight the former seems to be far more in the manner of the Social Contract and to contain views belonging essentially to Rousseau's constructive period. It would not, however, be safe to conclude from this that its date is really later. The Discourse on Inequality still has about it much of the rhetorical looseness of the prize essay; it aims not so much at close reasoning as at effective and popular presentation of a case. But, by reading between the lines, an attentive student can detect in it a great deal of the positive doctrine afterwards incorporated in the Social Contract. Especially in the closing section, which lays down the plan of a general treatment of the fundamental questions of politics, we are already to some extent in the atmosphere of the later works. It is indeed almost certain that Rousseau never attempted to put into either of the first two Discourses any of the positive content of his political theory. They were intended, not as final expositions of his point
