Which Enlightenment thinker authored The Spirit of Laws and argued that the best government includes a separation of powers?

• A. Voltaire
• B. Montesquieu
• C. Rousseau
• D. Locke

Answer: (B)

The idea being tested is how governing power should be organized to prevent tyranny: separating the tasks of making laws, enforcing laws, and interpreting laws. Montesquieu’s The Spirit of the Laws argues that liberty and political stability come from dividing government into distinct branches—legislative, executive, and judicial—with checks and balances so no one group can dominate. This framework became a cornerstone for modern constitutional design and influenced many democracies, including the United States. Voltaire is known for defending civil liberties and religious tolerance but didn’t author The Spirit of the Laws. Rousseau focused on the social contract and the general will rather than a formal separation of powers. Locke argued for natural rights and government by consent, with limits on authority, but he did not develop the explicit three-branch framework Montesquieu presented.
