The Social Contract, then, may be regarded either as a document of the French Revolution, or as one of the greatest books dealing with political philosophy. It is in the second capacity, as a work of permanent value containing truth, that it finds a place among the world's great books. It is in that capacity also that it will be treated in this introduction. Taking it in this aspect, we have no less need of historical insight than if we came to it as historians pure and simple. To understand its value we must grasp its limitations; when the questions it answers seem unnaturally put, we must not conclude that they are meaningless; we must see if the answer still holds when the question is put in a more up-to-date form.

First, then, we must always remember that Rousseau is writing in the eighteenth century, and for the most part in France. Neither the French monarchy nor the Genevese aristocracy loved outspoken criticism, and Rousseau had always to be very careful what he said. This may seem a curious statement to make about a man who suffered continual persecution on account of his subversive doctrines; but, although Rousseau was one of the most daring writers of his time, he was forced continually to moderate his language and, as a rule, to confine himself to generalisation instead of attacking particular abuses. Rousseau's theory has often been decried as too abstract and metaphysical. This is in many ways its great strength; but where it is excessively so, the accident of time is to blame. In the eighteenth century it was, broadly speaking, safe to generalise and unsafe to particularise. Scepticism and discontent were the prevailing temper of the intellectual classes, and a short-sighted despotism held that, as long as they were confined to these, they would do little harm. Subversive doctrines were only regarded as dangerous when they were so put as to appeal to the masses; philosophy was regarded as impotent. The intellectuals of the eighteenth century therefore generalised to their hearts' content, and as a rule suffered little for their lèse-majesté: Voltaire is the typical example of such generalisation. The spirit of the age favoured such methods, and it was therefore natural for Rousseau to pursue them. But his general remarks had such a way of bearing very obvious particular applications, and were so obviously inspired by a particular attitude towards the government of his day, that even philosophy became in his hands unsafe, and he was attacked for what men read between the lines of his works. It is owing to this faculty of giving his generalisations content and actuality that Rousseau has become the father of modern political philosophy. He uses the method of his time only to transcend it; out of the abstract and general he creates the concrete and universal.

Secondly, we must not forget that Rousseau's theories are to be studied in a wider historical environment. If he is the first of modern political theorists, he is also the last of a long line of Renaissance theorists, who in turn inherit and transform the concepts of mediæval thought. So many critics have spent so much wasted time in proving that Rousseau was not original only because they began by identifying originality with isolation: they studied first the Social Contract by itself, out of relation to earlier works, and then, having discovered that these earlier works resembled it, decided that everything it had to say was borrowed. Had they begun their study in a truly historical spirit, they would have seen that Rousseau's importance lies just in the new use he makes of old ideas, in the transition he makes from old to new in the general conception of politics. No mere innovator could have exercised such an influence or hit on so much truth. Theory makes no great leaps; it proceeds to new concepts by the adjustment and renovation of old ones. Just as theological writers on politics, from Hooker to Bossuet, make use of Biblical terminology and ideas; just as more modern writers, from Hegel to Herbert Spencer, make use of the concept of evolution, Rousseau uses the ideas and terms of the Social Contract theory. We should feel, throughout his work, his struggle to free himself from what is lifeless and outworn in that theory, while he develops out of it fruitful conceptions that go beyond its scope. A too rigid literalism in the interpretation of Rousseau's thought may easily reduce it to the possession of a merely "historical interest": if we approach it in a truly historical spirit, we shall be able to appreciate at once its temporary and its lasting value, to see how it served his contemporaries, and at the same time to disentangle from it what may be serviceable to us and for all time.

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 of view, but as partial and preliminary studies, in which his aim was far more destructive than constructive. It is clear that in first conceiving the plan of a work on Political Institutions, Rousseau cannot have meant to regard all society as in essence bad. It is indeed evident that he meant, from the first, to study human society and institutions in their rational aspect, and that he was rather diverted from his main purpose by the Academy of Dijon's competition than first induced by it to think about political questions. It need, therefore, cause no surprise that a work probably written before the Discourse on Inequality should contain the germs of the theory given in full in the Social Contract. The Discourse on Political Economy is important as giving the first sketch of the theory of the "General Will." It will readily be seen that Rousseau does not mean by "political economy" exactly what we mean nowadays. He begins with a discussion of the fundamental nature of the State, and the possibility of reconciling its existence with human liberty, and goes on with an admirable short study of the principles of taxation. He is thinking throughout of "political" in the sense of "public" economy, of the State as the public financier, and not of the conditions governing industry. He conceives the State as a body aiming at the well-being of all its members and subordinates all his views of taxation to that end. He who has only necessaries should not be taxed at all; superfluities should be supertaxed; there should be heavy imposts on every sort of luxury. The first part of the article is still more interesting. Rousseau begins by demolishing the exaggerated parallel so often drawn between the State and the family; he shows that the State is not, and cannot be, patriarchal in nature, and goes on to lay down his view that its real being consists in the General Will of its members. The essential features of the Social Contract are present in this Discourse almost as if they were commonplaces, certainly not as if they were new discoveries on which the author had just hit by some happy inspiration. There is every temptation, after reading the Political Economy, to suppose that Rousseau's political ideas really reached maturity far earlier than has generally been allowed.

The Social Contract finally appeared, along with Emile, in 1762. This year, therefore, represents in every respect the culmination of Rousseau's career. Henceforth, he was to write only controversial and confessional works; his theories were now developed, and, simultaneously, he gave to the world his views on the fundamental problems of politics and education. It is now time to ask what Rousseau's system, in its maturity, finally amounted to. The Social Contract contains practically the whole of his constructive political theory; it requires to be read, for full understanding, in connection with his other works, especially Emile and the Letters on the Mount (1764), but in the main it is self-contained and complete. The title sufficiently defines its scope. It is called The Social Contract or Principles of Political Right, and the second title explains the first. Rousseau's object is not to deal, in a general way, like Montesquieu, with the actual institutions of existing States, but to lay down the essential principles which must form the basis of every legitimate society. Rousseau himself, in the fifth book of the Emile, has stated the difference clearly. "Montesquieu," he says, "did not intend to treat of the principles of political right; he was content to treat of the positive right (or law) of established governments; and no two studies could be more different than these." Rousseau then conceives his object as being something very different from that of the Spirit of the Laws, and it is a wilful error to misconstrue his purpose. When he remarks that "the facts," the actual history of political societies, "do not concern him," he is not contemptuous of facts; he is merely asserting the sure principle that a fact can in no case give rise to a right. His desire is to establish society on a basis of pure right, so as at once to disprove his attack on society generally and to reinforce his criticism of existing societies.

Round this point centres the whole dispute about the methods proper to political theory. There are, broadly speaking, two schools of political theorists, if we set aside the psychologists. One school, by collecting facts, aims at reaching broad generalisations about what actually happens in human societies! the other tries to penetrate to the universal principles at the root of all human combination. For the latter purpose facts may be useful, but in themselves they can prove nothing. The question is not one of fact, but one of right.
