work in every legitimate society, but which will be in abeyance in all forms of despotism. He clearly means by it no more and no less than the fundamental principle of political association, the basis of the unity which enables us, in the State, to realise political liberty by giving up lawlessness and license. The presentation of this doctrine in the quasi-historical form of the Social Contract theory is due to the accident of the time and place in which Rousseau wrote. At the same time, the importance of the conception is best to be seen in the hard death it dies. Though no one, for a hundred years or so, has thought of regarding it as historical, it has been found so hard to secure any other phrase explaining as well or better the basis of political union that, to this day, the phraseology of the contract theory largely persists. A conception so vital cannot have been barren.
It is indeed, in Rousseau’s own thought, only one of the three different ways in which the basis of political union is stated, according to the preoccupation of his mind. When he is thinking quasi-historically, he describes his doctrine as that of the Social Contract. Modern anthropology, in its attempts to explain the complex by means of the simple, often strays further from the straight paths of history and reason. In a semi-legal aspect, using the terminology, if not the standpoint, of jurisprudence, he restates the same doctrine in the form of popular Sovereignty. This use tends continually to pass over into the more philosophical form which comes third. “Sovereignty is the exercise of the general will.” Philosophically, Rousseau’s doctrine finds its expression in the view that the State is based not on any original convention, not on any determinate power, but on the living and sustaining rational will of its members. We have now to examine first Sovereignty and then the General Will, which is ultimately Rousseau’s guiding conception.
Sovereignty is, first and foremost, a legal term, and it has often been held that its use in political philosophy merely leads to confusion. In jurisprudence, we are told, it has the perfectly plain meaning given to it
