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.
