Jefferson wrote that a number of authors exerted a general influence on the words of the Declaration. English political theorist John Locke is usually cited as one of the primary influences, a man whom Jefferson called one of "the three greatest men that have ever lived". In 1922, historian Carl L. Becker wrote, "Most Americans had absorbed Locke's works as a kind of political gospel; and the Declaration, in its form, in its phraseology, follows closely certain sentences in Locke's second treatise on government." The extent of Locke's influence on the American Revolution has been questioned by some subsequent scholars, however. Historian Ray Forrest Harvey argued in 1937 for the dominant influence of Swiss jurist Jean Jacques Burlamaqui, declaring that Jefferson and Locke were at "two opposite poles" in their political philosophy, as evidenced by Jefferson's use in the Declaration of Independence of the phrase "pursuit of happiness" instead of "property". Other scholars emphasized the influence of republicanism rather than Locke's classical liberalism. Historian Garry Wills argued that Jefferson was influenced by the Scottish Enlightenment, particularly Francis Hutcheson, rather than Locke, an interpretation that has been strongly criticized.
