Why obey? Why this government, and not another? Who owns the world? Six answers across four centuries — and the standing arguments, still in print, against each.
All modern political philosophy begins with a thought experiment: what would human life be like without political authority? Three answers, three regimes.
A war of all against all. "Solitary, poor, nasty, brutish, and short." (Leviathan, ch. XIII) Without a sovereign to keep us in awe, life is unbearable. Therefore: covenant; absolute sovereign; Leviathan.
A state of equality under natural law, generally peaceful but with "inconveniences" — no impartial judge. Therefore: limited government, by consent, to protect life, liberty, and estate. (Second Treatise on Government)
Originally a state of innocence: solitary, peaceful, free. Civilisation introduces inequality, vanity, dependence. The chains of property and society are forged before the chains of government. (Discourse on Inequality)
The state of nature is rarely meant as history. It is a normative device: by stripping away the institutions we have, we ask what they are for — and so why we should accept the ones we have. Different starting pictures yield different conclusions. Hobbes ends with sovereignty; Locke with limited government; Rousseau with the general will.
Thomas Hobbes · 1588 — 1679 · Malmesbury · Paris · London
Hobbes wrote Leviathan in exile in Paris during the English Civil War — a war in which both king and parliament had lost the power to keep the peace. The book is the first great work of modern political theory: materialist, individualist, geometric in ambition.
Hobbes's book is famous for its title page: a giant king, sword in one hand, crozier in the other, towering over a landscape. His body is composed of small figures — the citizens whose covenant he embodies. Above: Non est potestas Super Terram quae Comparetur ei. ("There is no power on earth comparable to him." — Job 41:24)
Hobbes's authoritarianism is unfashionable; his analysis of why we need authority remains the foundation. Schmitt, Oakeshott, Skinner — the great twentieth-century commentators — read Hobbes as the first to take political artifice seriously. The state, on Hobbes's view, is a human creation answerable for its work.
John Locke · 1632 — 1704 · Wrington · Oxford · Holland
The famous argument of Chapter V. The earth is given to mankind in common. But every person owns themselves and the labour of their body. By mixing labour with what is held in common, one makes it one's own — provided "enough, and as good" is left for others, and that nothing spoils.
Money loosens the spoilage proviso — gold does not rot. Locke is sometimes read as licensing inequality; sometimes (by C. B. Macpherson) as the theorist of "possessive individualism."
Government's authority derives from the consent of the governed. Tacit consent — using roads, trading under laws — counts. So does, controversially, the right of revolution: when government violates its trust, "the people are at liberty to provide for themselves by erecting a new legislative." (§220)
Locke's vocabulary — "life, liberty, and the pursuit of happiness" (Locke wrote "estate") — runs straight into the Declaration of Independence (1776). The Federalist Papers cite him by name. The Bill of Rights, the Fifth Amendment's protection of property, the very habit of justifying state action in terms of consent — all are, in part, Lockean.
Locke also held shares in the Royal African Company; the chapter "Of Slavery" in the Second Treatise is uncomfortable reading. Modern interpreters (Bernasconi, Mehta) have argued that Lockean liberalism was, from the beginning, entangled with empire and racial hierarchy. The argument is alive.
Jean-Jacques Rousseau · 1712 — 1778 · Geneva · Paris · Ermenonville
Rousseau is the most contradictory of the great moderns. Composer, novelist, autodidact, exile, paranoid, friend then enemy of every philosophe in Paris. The Social Contract is the political manifesto; Émile the book on education; the Discourses the historical-anthropological vision; the Confessions the first modern autobiography.
Not the will of all (the sum of private interests), but the will the citizens have when they aim at the common good. Legitimate law expresses the general will. To be forced to obey it is to be "forced to be free" (I.7) — the most contested phrase in the book; read either as Kantian autonomy or as totalitarian seed, depending on the reader.
Rousseau died eleven years before the French Revolution. The Jacobins read him devotionally; Robespierre kept a copy of The Social Contract in his pocket. The terror was carried out partly in his name — though Rousseau, who hated cities and crowds, would have been appalled.
Karl Marx · 1818 — 1883 · Trier · Paris · Brussels · London
Under capitalism, the worker is alienated from: (a) the product of their labour, (b) the act of labour itself, (c) their species-being (productive cooperation), and (d) other workers, who become competitors. Alienation is the key category of the early Marx; it links his philosophical anthropology to his political economy.
Marx is not, strictly, a political philosopher in the Locke or Rawls sense — he says little about institutional design after the revolution. But his critique reframed the question. After Marx, no liberal theorist could ignore the question: do formal liberties matter when material inequalities make them unusable?
Lenin, Stalin, Mao — each is a chapter; none uncontested. The Frankfurt School (Adorno, Horkheimer, Marcuse) developed Marxian critique of culture without revolutionary politics. Analytical Marxism (Cohen, Roemer, Elster) re-tooled Marx with formal methods. He remains a rolling argument.
In 1971 the Harvard professor John Rawls published A Theory of Justice, reviving political philosophy after a generation of analytic neglect. Three years later, his colleague Robert Nozick published Anarchy, State, and Utopia — a libertarian rebuttal so elegant it became a standard.
Behind the veil of ignorance — not knowing your gender, race, talents, wealth, or conception of the good — what principles would you choose for your society?
Lexical priority: liberty first, then opportunity, then the difference principle.
A distribution is just if it arose from a just past — by:
"Liberty upsets patterns." (Wilt Chamberlain) Any pattern of distribution will be disrupted by free choices, and to maintain it requires constant interference. Therefore: minimal state, restricted to protection.
Nozick's most famous thought experiment, designed to break "patterned" theories of justice (including Rawls's).
The Marxist philosopher G. A. Cohen, in Self-Ownership, Freedom and Equality (1995), argued that the choice scenario assumes background institutions — money, property, contracts — that already encode controversial distributive principles. The exchange "consents" to those institutions only after they are in place.
Politics happens at a scale no individual can take in. Hobbes saw the multitude as a danger; Rousseau hoped to discipline it through the general will; Marx looked for in it the agent of history; Rawls modelled it as a committee of strangers behind a veil. Photographs of the crowd remind us that the abstractions answer to a body, breathing and tired and angry, in a particular street.
The Sexual Contract (1988): the social contract presupposes a prior, unwritten contract by which men gain political control over women. The "individuals" of contract theory are gendered.
The Racial Contract (1997): a parallel argument. The social contract was, in fact, a racial contract — granting full personhood only to whites; reading it neutrally hides this.
With Amartya Sen: ask not what people have but what they can do and be. A list of central capabilities (life, bodily health, affiliation, play...) as the metric of justice.
Republicanism (1997): freedom is not non-interference (liberalism) but non-domination — not living at the mercy of another's will, even a benign one.
Legitimacy comes from the "ideal speech situation" — public reasoning under conditions free of coercion. Between Facts and Norms (1992).
The Wretched of the Earth (1961): colonialism's psychology, and the politics of decolonisation. A different starting point for thinking about the state.

Every news headline of the early twenty-first century is, when traced down, a quarrel one of these authors framed. Sovereignty, borders, war powers, the relation of the state of emergency to the rule of law — Hobbes saw the bones of those debates clearly in 1651.
Property, taxation, who has standing to revolt, on what occasion — Locke's Second Treatise still governs much of the rhetoric of American constitutional argument, even when his name is not invoked. He is a presence in every dispute over the just acquisition of resources, including the disputes over restitution he helped, in his own day, to obscure.
Equality of what? The Rawls–Sen–Nussbaum debate set the terms in which we now ask whether to measure progress by income, by capabilities, by happiness, by carbon. International institutions (the UN, the World Bank, the OECD) borrow from this vocabulary daily.
The Marxist questions about labour, surplus, ownership, and class have been driven out of polite economic discourse and back in again at least three times since 1970. They are unlikely to leave for good while the technologies that intensify the wage relation continue to develop.
And the Nozickean question — by what right does the state coerce me? — is the question to which every theory of taxation, conscription, regulation, and prohibition is, in the end, an answer.
Political philosophy is not a luxury. It is what we are doing badly when we stop doing it well.
Michael Sandel's Harvard "Justice" lectures, free on YouTube, are the best public introduction to the field — Aristotle, Kant, Mill, Locke, Rawls, all in succession. The In Our Time on the social contract is also worth an hour.

All political theory is the heir of the Greek polis. The disagreement is about who counts as a citizen.
