This constitution, which may at first sight be confounded with the federal constitutions which preceded it, rests upon a novel theory, which may be considered as a great invention in modern political science. In all the confederations which had been formed before the American constitution of 1789, the allied states agreed to obey the injunctions of a federal government: but they reserved to themselves the right of ordaining and enforcing the execution of the laws of the Union. The American states which combined in 1789 agreed that the federal government should not only dictate the laws, but it should execute its own enactments. In both cases the right is the same, but the exercise of the right is different; and this alteration produced the most momentous consequences.
In all the confederations which have been formed before the American Union, the federal government demanded its supplies at the hands of the separate governments; and if the measure it prescribed was onerous to any one of those bodies, means were found to evade its claims: if the state was powerful, it had recourse to arms; if it was weak, it connived at the resistance which the law of the Union, its sovereign, met with, and resorted to inaction under the plea of inability. Under these circumstances one of two alternatives has invariably occurred: either the most preponderant of the allied peoples has assumed the privileges of the federal authority, and ruled all the other states in its name,[154] or the federal government has been abandoned by its natural supporters, anarchy has arisen between the confederates, and the Union has lost all power of action.[155]
In America the subjects of the Union are not states, but private citizens: the national government levies a tax, not upon the state of Massachusetts, but upon each inhabitant of Massachusetts. All former confederate governments presided over communities, but that of the Union rules individuals; its force is not borrowed, but self-derived; and it is served by its own civil and military officers, by its own army, and its own courts of justice. It cannot be doubted that the spirit of the nation, the passions of the multitude, and the provincial prejudices of each state, tend singularly to diminish the authority of a federal authority thus constituted, and to facilitate the means of resistance to its mandates; but the comparative weakness of a restricted sovereignty is an evil inherent in the federal system. In America, each state has fewer opportunities of resistance, and fewer temptations to non-compliance; nor can such a design be put in execution (if indeed it be entertained), without an open violation of the laws of the Union, a direct interruption of the ordinary course of justice, and a bold declaration of revolt; in a word, without a decisive step, which men hesitate to adopt.
