in themselves they can prove nothing. The question is not one of fact, but one of right.

Rousseau belongs essentially to this philosophical school. He is not, as his less philosophic critics seem to suppose, a purely abstract thinker generalising from imaginary historical instances; he is a concrete thinker trying to get beyond they inessential and changing to the permanent and invariable basis of human society. Like Green, he is in search of the principle of political obligation, and beside this quest all others fall into their place as secondary and derivative. It is required to find a form of association able to defend and protect with the whole common force the person and goods of every associate, and of such a nature, that each, uniting himself with all, may still obey only himself, and remain as free as before. This is the fundamental problem of which the Social Contract provides the solution. The problem of political obligation is seen as including all other political problems, which fall into place in a system based upon it. How, Rousseau asks, can the will of the State help being for me a merely external will, imposing itself upon my own? How can the existence of the State be reconciled with human freedom? How can man, who is born free, rightly come to be everywhere in chains?

No-one could help understanding the central problem of the Social Contract immediately, were it not that its doctrines often seem to be strangely formulated. We have seen that this strangeness is due to Rousseau's historical position, to his use of the political concepts current in his own age, and to his natural tendency to build on the foundations laid by his predecessors. There are a great many people whose idea of Rousseau consists solely of the first words of the opening chapter of the Social Contract, "Man is born free, and everywhere he is in chains." But, they tell you, man is not born free, even if he is everywhere in chains. Thus at the very outset we are faced with the great difficulty in appreciating Rousseau. When we should naturally say "man ought to be free," or perhaps "man is born for freedom," he prefers to say "man is born free," by which he means exactly the same thing. There is doubtless, in his way of putting it, an appeal to a "golden age"; but this golden age is admittedly as imaginary as the freedom to which men are born is bound, for most of them, to be. Elsewhere Rousseau puts the point much as we might put it ourselves. "Nothing is more certain than that every man born in slavery is born for slavery.... But if there are slaves by nature, it is because there have been slaves against nature" (Social Contract, Book I, chap. ii).

We have seen that the contrast between the "state of nature" and the "state of society" runs through all Rousseau's work. The Emile is a plea for "natural" education; the Discourses are a plea for a "naturalisation" of society; the New Héloïse is the romantic's appeal for more "nature" in human relationships. What then is the position of this contrast in Rousseau's mature political thought? It is clear that the position is not merely that of the Discourses. In them, he envisaged only the faults of actual societies; now, he is concerned with the possibility of a rational society. His aim is to justify the change from "nature" to "society," although it has left men in chains. He is in search of the true society, which leaves men "as free as before." Altogether, the space occupied by the idea of nature in the Social Contract is very small. It is used of necessity in the controversial chapters, in which Rousseau is refuting false theories of social obligation; but when once he has brushed aside the false prophets, he lets the idea of nature go with them, and concerns himself solely with giving society the rational sanction he has promised. It becomes clear that, in political matters at any rate, the "state of nature" is for him only a term of controversy. He has in effect abandoned, in so far as he ever held it, the theory of a human golden age; and where, as in the Emile, he makes use of the idea of nature, it is broadened and deepened out of all recognition. Despite many passages in which the old terminology cleaves to him, he means by "nature" in this period not the original state of a thing, nor even its reduction to the simplest terms: he is passing over to the conception of "nature" as identical with the full development of capacity, with the higher! idea of human freedom. This view may be seen in germ even in the Discourse on Inequality, where, distinguishing self-respect (amour de soi) from egoism (amour-propre), Rousseau makes the former, the property of the "natural" man, consist not in the desire for self-aggrandisement, but in the seeking of satisfaction for reasonable desire accompanied by benevolence; whereas egoism is the preference of our own interests to those of others, self-respect merely puts us on an equal footing with our fellows. It is true that in the Discourse Rousseau is pleading against the development of many human faculties; but he is equally advocating the fullest development of those he regards as "natural," by which he means merely "good." The "state of society," as envisaged in the Social Contract, is no longer in contradiction to the "state of nature" upheld in the Emile, where indeed the social environment is of the greatest importance, and, though the pupil is screened from it, he is none the less being trained for it. Indeed the views given in the Social Contract are summarised in the fifth book of the Emile, and by this summary the essential unity of Rousseau's system is emphasised.

Rousseau's object, then, in the first words of the Social Contract, "is to inquire if, in the civil order, there can be any sure and certain, rule of administration, taking men as they are and laws as they might be." Montesquieu took laws as they were, and saw what sort of men they made: Rousseau, founding his whole system on human freedom, takes man as the basis, and regards him as giving himself what laws he pleases. He takes his stand on the nature of human freedom: on this he bases his whole system, making the will of the members the sole basis of every society.

In working out his theory, Rousseau makes use throughout of three general and, to some extent, alternative conceptions. These are the Social Contract, Sovereignty and the General Will. We shall now have to examine each of these in turn.

The Social Contract theory is as old as the sophists of Greece (see Plato, Republic, Book II and the Gorgias), and as I elusive. It has been adapted to the most opposite points of view, and used, in different forms, on both sides of every question to which it could conceivably be applied. It is frequent in mediæval writers, a commonplace with the theorists of the Renaissance, and in the eighteenth century already nearing its fall before a wider conception. It would be a long, as well as a thankless, task to trace its history over again: it may be followed best in D. G. Ritchie's admirable essay on it in Darwin and Hegel and Other Studies. For us, it is important only to regard it in its most general aspect, before studying the special use made of it by Rousseau. Obviously, in one form or another, it is a theory very easily arrived at. Wherever any form of government apart from the merest tyranny exists, reflection on the basis of the State cannot but lead to the notion that, in one sense or another, it is based on the consent, tacit or expressed, past or present, of its members. In this alone, the greater part of the Social Contract theory is already latent. Add the desire to find actual justification for a theory in facts, and, especially in an age possessed only of the haziest historical sense, this doctrine of consent will inevitably be given a historical setting. If in addition there is a tendency to regard society as something unnatural to humanity, the tendency will become irresistible. By writers of almost all schools,
