America's finest eighteenth-century student of political science, John Adams is also the least studied of the Revolution's key figures. By the time he became our second president, no American had written more about our government and not even Jefferson or Madison had read as widely about questions of human nature, natural right, political organization, and constitutional construction. Yet this staunch constitutionalist is perceived by many as having become reactionary in his later years and his ideas have been largely disregarded.
