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 in Austin’s famous definition. The Sovereign is “a determinate human superior, not in a habit of obedience to a like superior, but receiving habitual obedience from the bulk of a given society.” Where Sovereignty is placed is, on this view, a question purely of fact, and never of right. We have only to seek out the determinate human superior in a given society, and we shall have the Sovereign. In answer to this theory, it is not enough, though it is a valuable point, to show that such a determinate superior is rarely to be found. Where, for instance, is the Sovereign of England or of the British Empire? Is it the King, who is called the Sovereign? Or is it the Parliament, which is the legislature (for Austin’s Sovereign is regarded as the source of law)? Or is it the electorate, or the whole mass of the population, with or without the right of voting? Clearly all these exercise a certain influence in the making of laws. Or finally, is it now the Cabinet? For Austin, one of these bodies would be ruled out as indeterminate (the mass of the population) and another as responsible (the Cabinet). But are we to regard the House of Commons or those who elect it as forming part of the Sovereign? The search for a determinate Sovereign may be a valuable legal conception; but it has evidently nothing to do with political theory.
It is, therefore, essential to distinguish between the legal Sovereign of jurisprudence, and the political Sovereign of political science and philosophy. Even so, it does not at once become clear what this political Sovereign may be. Is it the body or bodies of persons in whom political power in a State actually resides? Is it merely the complex of actual institutions regarded as embodying the will of the society? This would leave us still in the realm of mere fact, outside both right and philosophy. The Sovereign, in the philosophical sense, is neither the nominal Sovereign, nor the legal Sovereign, nor the political Sovereign of fact and common sense: it is the consequence of the fundamental bond of union, the restatement of the doctrine of Social Contract, the foreshadowing of that of General Will. The Sovereign is that body in the State in which political power ought always to reside, and in which the right to such power does always reside.
The idea at the back of the philosophical conception of Sovereignty is, therefore, essentially the same as that we found to underlie the Social Contract theory. It is the view that the people, whether it can alienate its right or not, is the ultimate director of its own destinies, the final power from which there is no appeal. In a sense, this is recognised even by Hobbes, who makes the power of his absolute Sovereign, the predecessor of Austin’s “determinate human superior,” issue first of all from the Social Contract, which is essentially a popular act. The difference between Hobbes and Rousseau on this point is solely that Rousseau regards as inalienable a supreme power which Hobbes makes the people alienate in its first corporate action. That is to say, Hobbes in fact accepts the theory of popular supremacy in name only to destroy it in fact; Rousseau asserts the theory in its only logical form, and is under no temptation to evade it by means of false historical assumptions. In Locke, a distinction is already drawn between the legal and the actual Sovereign, which Locke calls “supreme power”; Rousseau unites the absolute Sovereignty of Hobbes and the “popular consent” of Locke into the philosophic doctrine of popular Sovereignty, which has since been the established form of the theory. His final view represents a return from the perversions of Hobbes to a doctrine already familiar to medieval and Renaissance writers; but it is not merely a return. In its passage the view has fallen into its place in a complete system of political philosophy.
In a second important respect Rousseau differentiates himself from Hobbes. For Hobbes, the Sovereign is identical with the government. He is so hot for absolutism largely because he regards revolution, the overthrow of the existing government, as at the same time the dissolution of the body politic, and a return to complete anarchy or to the “state of nature.” Rousseau and, to some extent, Locke meet this view by sharp division between the supreme power and the government. For Rousseau, they are so clearly distinct that even a completely democratic government is not at the same time the Sovereign; its members are sovereign only in a different capacity and as a different corporate body, just as two different societies may exist for different purposes with exactly the same members. Pure democracy, however, the government of the State by all the people in every detail, is not, as Rousseau says, a possible human institution. All governments are really mixed in character; and what we call a democracy is only a more or less democratic government. Government, therefore, will always be to some extent in the hands of selected persons. Sovereignty, on the other hand, is in his view absolute, inalienable,
