The 20 Greatest Books of Political Philosophy

Machiavelli stripped the moral pretense from political power and produced the founding text of modern political realism — read every century, denied every century, applied every century.

Adam Smith's eighteenth-century anatomy of how markets work — the founding text of modern economics and the intellectual scaffolding of every capitalist economy on earth.

Forty pages that reshaped the twentieth century — Marx and Engels wrote the most consequential political pamphlet in modern history, for better and for worse.

Hobbes built modern political philosophy from a single brutal premise — life without government is nasty, brutish, and short, and the state exists to prevent it.

Locke's founding text of liberal democratic theory — natural rights to life, liberty, and property, and the right to overthrow governments that violate them.

Tocqueville's nineteenth-century French analysis of the young American republic — still the most penetrating book ever written about how democracy actually works.

Marx's thousand-page anatomy of capitalism — surplus value, commodity fetishism, class struggle — the foundational text of every socialist movement since 1867.

Montesquieu's 1748 treatise introduced the separation of powers — the constitutional principle every liberal democracy since has borrowed from it.

Rousseau's 1762 treatise — "Man is born free, and everywhere he is in chains" — set the intellectual charge that detonated in the French Revolution twenty-seven years later.

Mill's 1859 treatise gave liberalism its core argument — the harm principle, and the claim that free speech and free thought are the only reliable engines of human progress.

Hayek's 1944 warning — that central planning leads inevitably to totalitarianism — became the intellectual foundation of postwar classical liberalism and the Thatcher–Reagan revolution.

Rawls's 1971 treatise — the veil of ignorance, justice as fairness — the most important work of political philosophy since Marx and the foundational text of postwar liberalism.

Cicero articulated the concept of natural law — the Roman political vocabulary that shaped medieval legal thought, the Enlightenment, and the American founding.

Weber's 1905 thesis — that Calvinist anxiety over predestination created the psychological conditions for capitalism — one of the founding works of sociology and still endlessly debated.

Schmitt's treatise — politics reduced to the friend/enemy distinction — the twentieth century's most penetrating critique of liberal democracy, whose influence on the authoritarian right remains undiminished.

Mazzini's treatise and the ideological architecture of Italian unification — the most influential theorist of nineteenth-century democratic nationalism and a shaping influence on everyone from Weizmann to Gandhi.

Gramsci's fragmentary Marxist theory, written in Italian prison to evade Mussolini's censors — the origin of "hegemony" and the theoretical grounding of Western Marxism and cultural studies.

Sorel's 1908 treatise — politics as driven by myth, not rational programs; the intellectual bridge between revolutionary socialism and fascism, and a book whose influence exceeds its readership.

Jünger's 1932 treatise — total mobilization, the Worker-Soldier figure; the work that shaped Heidegger's thinking and remains a central document of the European conservative revolution.

Fo's political farces — commedia dell'arte and medieval giullare traditions fused with radical leftist satire; the 1997 Nobel and Italy's most inventive postwar dramatist.
