But there were, as I have said, one or two facts of previous history, which gave the advocates of a national government a great advantage over their opponents, and went far towards settling the real merits of the two opposite systems. A federal system had been tried, and had broken down in complete prostration of all the appropriate energies and functions of government. The advocates of the opposite system, therefore, could point to all the failures and all the defects of the Confederation, in proof of the reasoning which they employed. In addition to this, they could adduce the same general tendency in all former confederacies of the same nature. But no experiment had been made by the people of the American States, of a government founded expressly on the national character and relations of their inhabitants; and if the merits of such a government were now only to be maintained by theoretical reasoning, on the other hand it had not suffered the injury of acknowledged defeat. The difficulty in the way of its adoption was its supposed tendency to absorb, and perhaps to annihilate, the sovereignties of the States. The advocates of the Virginia plan were called upon to show how the general sovereignty and jurisdiction which they proposed to give to their system could consist with a considerable, though subordinate, jurisdiction in the States. One of its moderate and candid opponents[71] declared that, if this could be shown, the objections to it ought to be surrendered; but if not, he thought that those objections must have their full force. But, from the very nature of the case, that which had not been demonstrated by experience could rest only upon opinion; and while the Virginia system made no other provision for State defence against encroachments of the general government than such as might be found in the election by the State legislatures of the national Senate, the apprehensions of the smaller States could not be satisfied, however admirable the theory, and however able might be the reasoning by which it was supported.
