What is Madison's thesis?

Madison's thesis, primarily articulated in his writings such as "Federalist No. 10," argues for the importance of a large republic to control factions and prevent tyranny. He posits that a diverse population will lead to a greater variety of interests, making it difficult for any single faction to dominate. By extending the sphere of representation, Madison believes that a well-structured government can balance competing interests and uphold democracy. This framework is foundational to his vision of a functional, balanced government.
