the State will be represented as having arisen, in some remote age, out of a compact or, in more legal phrase, contract between two or more parties. The only class that will be able to resist the doctrine is that which maintains the divine right of kings, and holds that all existing governments were were imposed on the people by the direct interposition of God. All who are not prepared to maintain that will be partisans of some form or other of the Social Contract theory.

It is, therefore, not surprising that we find among its advocates writers of the most opposite points of view. Barely stated, it is a mere formula, which may be filled in with any content from absolutism to pure republicanism. And, in the hands of some at least of its supporters, it turns out to be a weapon that cuts both ways. We shall be in a better position to judge of its usefulness when we have seen its chief varieties at work.

All Social Contract theories that are at all definite fall under one or other of two heads. They represent society as based on an original contract either between the people and the government, or between all the individuals composing the State. Historically, modern theory passes from the first to the second of these forms.

The doctrine that society is founded on a contract between the people and the government is of mediæval origin. It was often supported by references to the Old Testament, which contains a similar view in an unreflective form. It is found in most of the great political writers of the sixteenth century; in Buchanan, and in the writings of James I: it persists into the seventeenth in the works of Grotius and Puffendorf. Grotius is sometimes held to have stated the theory so as to admit both forms of contract; but it is clear that he is only thinking of the first form as admitting democratic as well as monarchical government. We find it put very clearly by the Convention Parliament of 1688, which accuses James II of having "endeavoured to subvert the constitution of the kingdom by breaking the original contract between king and people." While Hobbes, on the side of the royalists, is maintaining the contract theory in its second form, the Parliamentarian Algernon Sidney adheres to the idea of a contract between the people and the government.

In this form, the theory clearly admits of opposite interpretations. It may be held that the people, having given itself up once for all to its rulers, has nothing more to ask of them, and is bound to submit to any usage they may choose to inflict. This, however, is not the implication most usually drawn from it. The theory, in this form, originated with theologians who were also lawyers. Their view of a contract implied mutual obligations; they regarded the ruler as bound, by its terms, to govern constitutionally. The old idea that a king must not violate the sacred customs of the realm passes easily into the doctrine that he must not violate the terms of the original contract between himself and his people. Just as in the days of the Norman kings, every appeal on the part of the people for more liberties was couched in the form of a demand that the customs of the "good old times" of Edward the Confessor should be respected, so in the seventeenth century every act of popular assertion or resistance was stated as an appeal to the king not to violate the contract. The demand was a good popular cry, and it seemed to have the theorists behind it. Rousseau gives his refutation of this view, which he had, in the Discourse on Inequality, maintained in passing, in the sixteenth chapter of the third book of the Social Contract. (See also Book I, chap, iv, init.) His attack is really concerned also with the theory of Hobbes, which in some respects resembles, as we shall see, this first view; but, in form at least, it is directed against this form of contract. It will be possible to examine it more closely, when the second view has been considered.

The second view, which may be called the Social Contract theory proper, regards society as originating in, or based on, an agreement between the individuals composing it. It seems to be found first, rather vaguely, in Richard Hooker's Ecclesiastical Polity, from which Locke largely borrowed: and it reappears, in varying forms, in Milton's Tenure of Kings and Magistrates, in Hobbes's Leviathan, in Locke's Treatises on Civil Government, and in Rousseau. The best-known instance of its actual use is by the Pilgrim Fathers on the Mayflower in 1620, in whose declaration occurs the phrase, "We do solemnly and mutually, in the presence of God and of one another, covenant and combine ourselves together into a civil body politic." The natural implication of this view would seem to be the corollary of complete popular Sovereignty which Rousseau draws. But before Rousseau's time it had been used to support views as diverse as those which rested on the first form. We saw that, in Grotius's great work, De Jure Belli et Pacis, it was already possible to doubt which of the two theories was being advocated. The first theory was, historically, a means of popular protest against royal aggression. As soon as popular government was taken into account, the act of contract between people and government became in effect merely a contract between the individuals composing the society, and readily passed over into the second form.

The second theory, in its ordinary form, expresses only the view that the people is everywhere Sovereign, and that, in the phrase of Milton's treatise, "the power of kings and magistrates is only derivative." Before, however, this view had been worked up into a philosophical theory, it had already been used by Hobbes to support precisely opposite principles. Hobbes agrees that the original contract is one between all the individuals composing the State, and that the government is no party to it; but he regards the people as agreeing, not merely to form a State, but to invest a certain person or certain persons with the government of it. He agrees that the people is naturally supreme, but regards it as alienating its Sovereignty by the contract itself, and delegating its power, wholly and for ever, to the government. As soon, therefore, as the State is set up, the government becomes for Hobbes the Sovereign; there is no more question of popular Sovereignty, but only of passive obedience: the people is bound, by the contract, to obey its ruler, no matter whether he governs well or ill. It has alienated all its rights to the Sovereign, who is, therefore, absolute master. Hobbes, living in a time of civil wars, regards the worst government as better than anarchy, and is, therefore, at pains to find arguments in support of any form of absolutism. It is easy to pick holes in this system, and to see into what difficulties a conscientious Hobbist might be led by a revolution. For as soon as the revolutionaries get the upper hand, he will have to sacrifice one of his principles: he will have to side against either the actual or the legitimate Sovereign. It is easy also to see that alienation of liberty, even if possible for an individual, which Rousseau denies, cannot bind his posterity. But, with all its faults, the view of Hobbes is on the whole admirably, if ruthlessly, logical, and to it Rousseau owes a great deal.

The special shape given to the second Social Contract theory by Hobbes looks, at first sight, much like a combination, into a single act, of both the contracts. This, however, is not the view he adopts. The theory of a contract between government and people had, as we have seen, been used mainly as a support for popular liberties, a means of assertion against the government. Hobbes, whose whole aim is to make his government Sovereign, can only do this by leaving the government outside the contract: he thus avoids the necessity of submitting it to any obligation whatsoever, and leaves it absolute and irresponsible. He secures, in fact, not merely a State which has unbounded rights against the individual, but a determinate authority with the
