Words Matter
A plain-language glossary for the words that shape public life.
Political Systems & Ideologies
Government structures and political philosophies that shape how power is distributed, who makes decisions, and how authority is justified. These terms are often used loosely. This section pins down their actual meanings and explains how they function in practice.
Libertarian
A political ideology that emphasizes individual freedom, limited government, and strong protections for personal and economic choice. Libertarianism prioritizes restricting state power, favoring free markets and narrowly defined government functions.
Liberalism
A political philosophy centered on individual rights, civil liberties, the rule of law, and limits on concentrated power. While modern partisan uses of “liberal” vary widely, the underlying liberal tradition seeks to ensure that governments protect personal freedoms and remain accountable to the public.
Conservatism
A political philosophy that emphasizes preserving established institutions, traditions, and social order. It generally favors cautious, incremental change over rapid transformation. While its specific policy positions vary by country and period, its core purpose is to maintain continuity and stability in public life.
Communism
A political and economic ideology envisioning a classless society with collective ownership of the means of production. In theory, wealth and power would be distributed based on need rather than market forces or private property. In practice, regimes identifying as communist have often centralized authority in a single party-state.
