The present constitution of the Union was formed at a later period than those of the majority of the states, and it may have derived some melioration from past experience. But we shall be led to acknowledge that this is only a secondary cause of its superiority, when we recollect that eleven new states have been added to the American confederation since the promulgation of the federal constitution, and that these new republics have always rather exaggerated than avoided the defects which existed in the former constitutions. The chief cause of the superiority of the federal constitution lay in the character of the legislators who composed it. At the time when it was formed the dangers of the confederation were imminent, and its ruin seemed inevitable. In this extremity the people chose the men who most deserved the esteem, rather than those who had gained the affections of the country. I have already observed, that distinguished as almost all the legislators of the Union were for their intelligence, they were still more so for their patriotism. They had all been nurtured at a time when the spirit of liberty was braced by a continual struggle against a powerful and predominant authority. When the contest was terminated, while the excited passions of the populace persisted in warring with dangers which had ceased to threaten them, these men stopped short in their career; they cast a calmer and more penetrating look upon the country which was now their own; they perceived that the war of independence was definitely ended, and that the only dangers which America had to fear were those which might result from the abuse of the freedom she had won. They had the courage to say what they believed to be true, because they were animated by a warm and sincere love of liberty; and they ventured to propose restrictions, because they were resolutely opposed to destruction.[153] The greater number of the constitutions of the states assign one year for the duration of the house of representatives, and two years for that of the senate; so that members of the legislative body are constantly and narrowly tied down by the slightest desires of their constituents. The legislators of the Union were of opinion that this excessive dependence of the legislature tended to alter the nature of the main consequences of the representative system, since it vested the source not only of authority, but of government, in the people. They increased the length of the time for which the representatives were returned, in order to give them freer scope for the exercise of their own judgment.
