Rousseau tries to do this by an adaptation of the doctrine of the “three powers.” But instead of three independent powers sharing the supreme authority, he gives only two, and makes one of these wholly dependent on the other. He substitutes for the coordination of the legislative, the executive, and the judicial authorities, a system in which the legislative power, or Sovereign, is always supreme, the executive, or government, always secondary and derivative, and the judicial power merely a function of government. This division he makes, naturally, one of will and power. The government is merely to carry out the decrees, or acts of will, of the Sovereign people. Just as the human will transfers a command to its members for execution, so the body politic may give its decisions force by setting up authority which, like the brain, may command its members. In delegating the power necessary for the execution of its will, it is abandoning none of its supreme authority. It remains Sovereign, and can at any moment recall the grants it has made. Government, therefore, exists only at the Sovereign’s pleasure, and is always revocable by the sovereign will.
It will be seen, when we come to discuss the nature of the General Will, that this doctrine really contains the most valuable part of Rousseau’s theory. Here, we are concerned rather with its limitations. The distinction between legislative and executive functions is in practice very hard to draw. In Rousseau’s case, it is further complicated by the presence of a second distinction. The legislative power, the Sovereign, is concerned only with what is general, the executive only with what is particular. This distinction, the full force of which can only be seen in connection with the General Will, means roughly that a matter is general when it concerns the whole community equally, and makes no mention of any particular class; as soon as it refers to any class or person, it becomes particular, and can no longer form the subject matter of an act of Sovereignty. However just this distinction may seem in the abstract, it is clear that its effect is to place all the power in the hands of the executive: modern legislation is almost always concerned with particular classes and interests. It is not, therefore, a long step from the view of Rousseau to the modern theory of democratic government, in which the people has little power beyond that of removing its rulers if they displease it. As long, however, as we confine our view to the city-state of which Rousseau is thinking, his distinction is capable of preserving for the people a greater actual exercise of will. A city can often generalise where a nation must particularise.
It is in the third book of the Social Contract, where Rousseau is discussing the problem of government, that it is most essential to remember that his discussion has in view mainly the city-state and not the nation. Broadly put, his principle of government is that democracy is possible only in small States, aristocracy in those of medium extent, and monarchy in great States (Book III, chap. III). In considering this view, we have to take into account two things. First, he rejects representative government; will being, in his theory, inalienable, representative Sovereignty is impossible. But, as he regards all general acts as functions of Sovereignty, this means that no general act can be within the competence of a representative assembly. In judging this theory, we must take into account all the circumstances of Rousseau’s time. France, Geneva and England were the three States he took most into account. In France, representative government was practically nonexistent; in Geneva, it was only partially necessary; in England, it was a mockery, used to support a corrupt oligarchy against a debased monarchy. Rousseau may well be pardoned for not taking the ordinary modern view of it. Nor indeed is it, even in the modern world, so satisfactory an instrument of the popular will that we can afford wholly to discard his criticism. It is one of the problems of the day to find some means of securing effective popular control over a weakened Parliament and a despotic Cabinet.
The second factor is the immense development of local government. It seemed to Rousseau that, in the nation-state, all authority must necessarily pass, as it had in France, to the central power. Devolution was hardly dreamed of; and Rousseau saw the only means of securing effective popular government in a federal system, starting from the small unit as Sovereign. The nineteenth century has proved the falsehood of much of his theory of government; but there are still many wise comments and fruitful suggestions to be found in the third book of the Social Contract and in the treatise on the Government of Poland, as well as in his adaptation and criticism of the Polysynodie of the Abbé de Saint-Pierre, a scheme of local government for France, born out of its due time.
The point in Rousseau’s theory of Sovereignty that offers most difficulty is his view (Book II, chap. VII) that, for every State, a Legislator is necessary. We shall understand the section only by realising that the legislator is, in fact, in Rousseau’s system, the spirit of institutions personified; his place, in a developed society, is taken by the whole complex of social custom,
