in which all men, rich and poor, magistrates and subjects, officers and people, masters and servants, the first citizen and the last, are equally subject to the laws." Virtue versus commerce The open question, as Pocock suggested, of the conflict between personal economic interest (grounded in Lockean liberalism) and classical republicanism, troubled Americans. Jefferson and Madison roundly denounced the Federalists for creating a national bank as tending to corruption and monarchism; Alexander Hamilton staunchly defended his program, arguing that national economic strength was necessary for the protection of liberty. Jefferson never relented but by 1815 Madison switched and announced in favor of a national bank, which he set up in 1816. John Adams often pondered the issue of civic virtue. Writing Mercy Otis Warren in 1776, he agreed with the Greeks and the Romans, that, "Public Virtue cannot exist without private, and public Virtue is the only Foundation of Republics." Adams insisted, "There must be a positive Passion for the public good, the public Interest, Honor, Power, and Glory, established in the Minds of the People, or there can be no Republican Government, nor any real Liberty. And this public Passion must be Superior to all private Passions. Men must be ready, they must pride themselves, and be happy to sacrifice their private Pleasures, Passions, and Interests, nay their private Friendships and dearest connections, when they Stand in Competition with the Rights of society." Adams worried that a businessman might have financial interests that conflicted with republican duty; indeed, he was especially suspicious of banks. He decided that history taught that "the Spirit of Commerce ... is incompatible with that purity of Heart, and Greatness of soul which is necessary for a happy Republic." But so much of that spirit of commerce had infected America. In New England, Adams noted, "even the Farmers and Tradesmen are addicted to Commerce." As a result, there was "a great Danger that a Republican Government would be very factious and turbulent there." Other influences A second stream of thought growing in significance was the classical liberalism of John Locke, including his theory of the "social contract". This had a great influence on the revolution as it implied the inborn right of the people to overthrow their leaders should those leaders betray the agreements implicit in the sovereign-follower relationship. Historians find little trace of Jean-Jacques Rousseau's influence in America. In terms of writing state and
