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 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 medieval 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, 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 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 medieval 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
