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.
