It has become something of a cliché for contemporary scholars to assert that Madison turned Montesquieu on his head and thereafter give little thought to the Frenchman’s theory that republics must remain limited in territorial size. Madison did indeed present a formidable challenge to Montesquieu’s theory, but I will demonstrate in this dissertation that the authors of the Federalist Papers arrived at the extended sphere by following a theoretical pathway already cemented by the French philosopher. I will also show that Madison’s “practical sphere” ultimately concedes to Montesquieu that excessive territorial size and high levels of heterogeneity will overwhelm the citizens of a republic and enable the few to oppress the many. The importance of this dissertation is its finding that the principal mechanism devised by the Federalists for dealing with factions—the enlargement of the sphere—was crafted specifically for the purpose of moderating interests, classes, and sects within an otherwise relatively homogeneous nation. Consequently, the diverse republic that is America today may be exposed to the existential threat anticipated by Montesquieu’s theory of size—the plutocratic oppression of society by an elite class that employs the strategy of divide et impera.

Francis Bacon (1561-1626) is recognized as a founder of the modern scientific project and a forerunner of the modern era of political thought. He advocated the development of an active science that would enable human beings to control nature in order to relieve man's estate. To accomplish this, Bacon argues that we must reconstruct all arts and sciences upon a more solid foundation. In reconstructing the arts and sciences, Bacon subtly changes the meaning of foundational religious, political, and scientific notions in order to better suit his project of progress. As the inheritors of his vision, turning to Bacon helps recover foundational considerations that have been forgotten as a result of his success. This dissertation approaches Bacon's thought through an analysis of his New Atlantis, a fable that envisions the completion of his project. I also turn to his other political, scientific, and religious works as appropriate to supply what is omitted in the fable. I find that although his revision of religious, scientific, and political foundations is conducted subtly they are nevertheless revolutionary, and essential for preparing the various outlooks that characterize the modern world.
