Liberalism is one of the most frequently used—and most misunderstood—ideas in political thought. Often celebrated as the foundation of freedom and equality, and just as often criticized as the cause of moral and social decline, its true history is far more complex than popular narratives suggest. This excerpt explores the origins and evolution of liberalism, tracing its roots to the French Revolution, its intellectual development in France and Germany, and its later transformation in America. It challenges common assumptions and reveals liberalism as a tradition deeply concerned with morality, civic duty, social justice, and the common good.
