Though the constitution of the people is congenital, like the constitution of an individual, and cannot be radically changed without the destruction of the state, it must not be supposed that it is wholly withdrawn from the action of the reason and free-will of the nation, nor from that of individual statesmen. All created things are subject to the law of development, and may be developed either in a good sense or in a bad; that is, may be either completed or corrupted. All the possibilities of the national constitution are given originally in the birth of the nation, as all the possibilities of mankind were given in the first man. The germ must be given in the original constitution. But in all constitutions there is more than one element, and the several elements maybe developed pari passu, or unequally, one having the ascendency and suppressing the rest. In the original constitution of Rome the patrician element was dominant, showing that the patriarchal organization of society still retained no little force. The king was only the presiding officer of the senate and the leader of the army in war. His civil functions corresponded very nearly to those of a mayor of the city of New York, where all the effective power is in the aldermen, common council, and heads of departments. Except in name he was little else than a pageant. The kings, no doubt, labored to develop and extend the royal element of the constitution. This was natural; and it was equally natural that they should be resisted by the patricians. Hence when the Tarquins, or Etruscan dynasty, undertook to be kings in fact as well as in name, and seemed likely to succeed, the patricians expelled them, and supplied their place by two consuls annually elected. Here was a modification, but no real change of the constitution. The effective Power, as before, remained in the senate.
But there was from early times a plebeian element in the population of the city, though forming at first no part of the political people. Their origin is not very certain, nor their original position in the city. Historians give different accounts of them. But that they should, as they increased in numbers, wealth, and importance, demand admission into the political society, religious or solemn marriage, a voice in the government, and the faculty of holding civil and military offices, was only in the order of regular development. At first the patricians fought them, and, failing to subdue them by force, effected a compromise, and bought up their leaders. The concession which followed of the tribunitial veto was only a further development. By that veto the plebeians gained no initiative, no positive power, indeed, but their tribunes, by interposing it, could stop the proceedings of the government. They could not propose the measures they liked, but they could prevent the legal adoption of measures they disliked--a faculty Mr. Calhoun asserted for the several States of the American Union in his doctrine of nullification, or State veto, as he called it. It was simply an obstructive power.
