The aim of every political Constitution, is or ought to be first to obtain for rulers men who possess most wisdom to discern, and most virtue to pursue, the common good of society; and in the next place, to take the most effectual precautions for keeping them virtuous whilst they continue to hold their public trust.
James Madisonthere ought always to be a constitutional method of giving efficacy to constitutional provisions. What for instance would avail restrictions on the authority of the state legislatures, without some constitutional mode of enforcing the observance of them? . . . This power must either be a direct negative on the state laws, or an authority in the federal courts, to over-rule such as might be in manifest contravention of the articles of union.
James Madison
