Which paper argues for checks and balances; ambition counteracts ambition?

• A. Federalist 39
• B. Federalist 51
• C. Brutus 3
• D. Federalist 10

Answer: (B)

The idea being tested is that powers should be separated and each branch should have enough authority to check the others, so no one part of government can dominate. Federalist 51 makes this explicit: it argues that government is made stronger and liberty safer when ambition within each branch counteracts ambition in the others. Madison explains that by giving each branch its own powers and checks—like vetoes, appointments, oversight, and judicial review—the political fight over power becomes a safeguard rather than a threat to liberty. The famous line about ambition counteracting ambition captures the whole mechanism: the drive for power in one branch acts as a counterweight to the drive for power in the others, preventing tyranny. Other writings touch on related themes but not this specific mechanism. Brutus 3 critiques centralized authority, Federalist 10 analyzes factions, and Federalist 39 discusses federal structure, but Federalist 51 is the one that directly and explicitly argues for checks and balances driven by competing ambitions.
