If two men ride on one horse, one of them must ride in front, and this sober physical truth is equally applicable to the realm of politics. No paper constitution, however deserving of veneration, can prevent there being some force in every nation capable of making itself supreme if it chooses to do so. It may be the constituencies, as in England at the end of the nineteenth century; the people consulted in mass, as in the United States; or the army, as in England in the middle of the seventeenth century. Such supremacy may be subjected to the checks of written or unwritten constitutions, and may be thus thrust into the background till called forth by some special crisis; but in the long run it is impossible to prevent supreme power from exerting itself. The defect of Oliver's fourth fundamental was that it sought to divide the control of the army, or, in other words, Sovereignty, between Protector and Parliament, at a time when the Protector was powerless to act in defiance of the army. It is useless to deny that he was perfectly in the right in hesitating to hand over supreme power to a Parliament uncontrolled by the nation, and capable of using its financial authority to demolish any system of government that might stand in the way of the ambitions of its members. It is equally undeniable that, as he was unable to depend on the nation as a whole, he had nothing to fall back upon except a Protectorate which, in reality, was controlled by the will of the leading officers, who found in the provisions of the Instrument which they had themselves originated the means of perpetuating their own power by securing--irrespective of the concurrence of Parliament or nation--the levy of taxes, the amount of which was fixed by the Protector and Council alone.
