Revolution

Plato gives the Western tradition its first systematic theory of political revolution. In Books VIII and IX of the Republic, he traces a descending sequence: aristocracy degenerates into timocracy when the guardians begin to value honor over wisdom, timocracy into oligarchy when honor gives way to wealth, oligarchy into democracy when the poor revolt against the rich, and democracy into tyranny when the demagogue rises from the chaos of unlimited freedom. Each transition is a revolution, and each is driven by the corruption of the class that rules.

The mechanism is psychological as much as political. Each regime corresponds to a type of soul: the timocratic man is ruled by spiritedness, the oligarchic by appetite for money, the democratic by appetite without hierarchy, the tyrant by the worst of all appetites. Revolution happens when a city's ruling principle can no longer sustain its authority, when the contradictions in its way of life become unbearable. The children of the guardians grow soft; the children of the oligarchs grow poor; the democratic man's children grow lawless.

What makes Plato's account distinctive is its fatalism. Revolution is not a choice but a cycle. The question is not whether a regime will fall, but when and into what. Only the philosopher-king, who rules by knowledge and not by interest, can arrest the descent, and Plato is not confident that such a ruler will appear.

Plato's cycle of regimes became the framework against which every later thinker on revolution had to argue. Aristotle accepted the premise that constitutions change but rejected the fixed sequence. The modern revolutionaries had to explain why their revolutions could escape the wheel.

Aristotle devotes the entirety of Politics Book V to the causes, varieties, and prevention of revolution (stasis). Where Plato described a single descending cycle, Aristotle insists that revolutions follow no fixed order. They occur in every type of constitution. Democracies, oligarchies, and mixed regimes all face the threat of overthrow, and the causes differ in each case.

The general cause is always inequality, but it takes two forms. In democracies, the many demand absolute equality and resent any distinction. In oligarchies, the few demand superiority and resent any sharing of power. Revolution breaks out when either party feels that it has less than it deserves. The methods are force and fraud: sometimes a faction seizes the government directly, sometimes it manipulates institutions from within until the constitution is changed without anyone noticing. Aristotle catalogs the specific triggers with empirical precision: insults to honor, disproportionate gains, fear of prosecution, contempt, territorial disputes.

His prescription is the mixed constitution, the politeia that balances the claims of wealth and number, giving each faction enough to prevent desperation. Moderate regimes, those with a large middle class and laws that distribute office fairly, are the most stable. The legislator's art is not to build a perfect city but to build one that can endure.

Aristotle's empirical approach to revolution became the foundation for later constitutional thinking. His insight that stability depends on a large middle class and proportional justice runs from Aquinas through Montesquieu to the Federalists.

Aquinas takes on the question that Aristotle left largely practical and gives it a moral framework. In the Summa Theologica, he defines sedition as a special sin against the common good, a mortal sin because it tears apart the unity of the community. But then he makes a decisive distinction: resistance to a tyrannical government is not sedition. The tyrant, by oppressing his subjects for private advantage, is the one who disrupts the common good. Those who resist him defend it.

This argument rests on Aquinas's broader political theology. Government exists to serve the common good; its authority derives from God through the natural law. When a ruler governs well, obedience is a duty. When he governs tyrannically, he forfeits his claim to authority. Aquinas is cautious about the practical implications. In On Kingship, he warns that rebellion can produce worse evils than the tyranny it opposes. The community, not private individuals, must judge when resistance is warranted. And passive endurance of a moderate tyranny is preferable to the risks of civil war.

Still, the principle is established: political authority is conditional. A ruler who violates the common good has, in a moral sense, already overthrown the legitimate order. The people who resist him are restoring it. This becomes the seed of the right of resistance that Locke would later develop into full constitutional theory.

Aquinas established the moral vocabulary of justified resistance that would echo through the Reformation, the English Civil War, and the American founding. Locke's argument that a tyrant puts himself in a state of war with the people is a secularized version of Aquinas's claim that the tyrant is the true seditious one.

Machiavelli breaks with the classical tradition by refusing to treat political upheaval as a disease. In the Discourses on Livy, he argues that the tumults between the Roman Senate and the plebs were not signs of corruption but the source of Roman liberty. Every republic contains two opposed humors: the great desire to dominate, and the people desire not to be dominated. When institutions force these humors into productive conflict, the result is good laws and political vitality.

This does not mean Machiavelli endorses all revolutions. In The Prince, he is brutally clear about what happens when a new order is founded: "There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things." The innovator has enemies in all who profited from the old order and only lukewarm defenders in those who might profit from the new. Founding requires virtù, the combination of boldness, foresight, and ruthlessness that allows a leader to impose form on chaotic matter.

The distinction is between revolutionary violence that founds or renews a republic, and violence that merely destroys. Moses, Romulus, and Theseus used force to establish new orders that outlasted them. A revolution that serves only private ambition is not a founding but a crime. Machiavelli judges the act by its results over generations, not by its morality in the moment.

Machiavelli's rehabilitation of political conflict as a source of freedom rather than a symptom of decay influenced Rousseau's theory of the general will and, more directly, Marx's insistence that class struggle is the engine of history.

Hobbes writes the Leviathan in the shadow of the English Civil War, and his theory of sovereignty is designed to make revolution logically impossible. The argument runs as follows: in the state of nature, life is "solitary, poor, nasty, brutish, and short." To escape this condition, individuals covenant with one another to transfer their right of self-governance to a sovereign. Once this transfer is made, it is irrevocable. The sovereign cannot be accused of injustice because justice itself is defined by the sovereign's law. Subjects who rebel dissolve the covenant and return themselves to the state of nature, which is to say, to war.

Hobbes identifies the causes of rebellion with clinical precision in Chapter 29: seditious doctrines, appeals to private conscience, the division of sovereign power, and the reading of Greek and Roman authors who praised tyrannicide. He treats these as diseases of the body politic. The classical tradition's approval of resistance to tyrants is, for Hobbes, one of the primary causes of civil dissolution. People read Aristotle and Cicero and convince themselves that killing a king is virtuous. The result is not liberty but slaughter.

The only exception Hobbes allows is the right of self-preservation. A subject condemned to death may resist, because the right to preserve one's own life cannot be transferred. But this is individual self-defense, not collective revolution. There is no right of the people as a body to judge or overthrow the sovereign.

Hobbes forced every subsequent theorist of revolution to answer a hard question: if political authority is the only alternative to anarchy, on what grounds can the overthrow of that authority be anything other than a return to chaos? Locke's entire Second Treatise is, in many ways, a reply to this challenge.

Locke's Second Treatise is the philosophical charter of the right of revolution. Against Hobbes, he argues that political authority rests on trust, not on an irrevocable transfer of rights. The people establish government for the preservation of their lives, liberties, and estates. When the legislature or the executive acts contrary to this trust, by making arbitrary laws, seizing property without consent, or delivering the people into subjection, the government dissolves itself. It is the ruler, not the people, who has committed the first act of rebellion.

Locke is careful to distinguish between the dissolution of government and the dissolution of society. When a government is overthrown, the community does not return to the state of nature. It retains its capacity to reconstitute political authority. The people are the judge of when the trust has been violated, and their judgment is final, not because they are always right, but because there is no earthly authority above them to which they can appeal. "Where the body of the people, or any single man, is deprived of their right, or is under the exercise of a power without right, and have no appeal on earth, then they have a liberty to appeal to heaven."

This is not an invitation to perpetual instability. Locke argues that people are slow to rebel and will endure considerable misgovernment before taking action. "Great mistakes in the ruling part, many wrong and inconvenient laws, and all the slips of human frailty will be borne by the people without mutiny or murmur." It is only a long train of abuses, a pattern that reveals systematic intent, that justifies revolution.

Locke's theory of the right of revolution became the direct intellectual foundation of the American Declaration of Independence. Jefferson's "long train of abuses" echoes Locke almost verbatim, and the Federalists built their constitutional architecture on the premise that government is a revocable trust.

Montesquieu shifts the question of revolution from right to prevention. He is less interested in whether rebellion is justified than in how a political order can be designed so that rebellion becomes unnecessary. The answer is structural: the separation of legislative, executive, and judicial powers. When these functions are concentrated in the same hands, whether of one, a few, or many, liberty is destroyed and tyranny follows. When they are distributed, each power checks the others, and the system sustains itself through its own internal tensions.

His analysis in Book XI of The Spirit of the Laws draws on the English constitution, which Montesquieu idealizes as a government whose "direct end" is political liberty. The king executes, the parliament legislates, the courts judge. None can dominate the others. This produces a moderate government, one that governs by fixed laws rather than by arbitrary will. Moderate government does not eliminate political conflict, but it channels conflict into institutional forms that prevent the accumulation of grievances that produces revolution.

Montesquieu also attends to the social and cultural conditions that sustain or undermine political stability. In Book XIX, he argues that the "spirit" of a nation, its manners, customs, and character, shapes its institutions as much as formal laws do. A constitution that does not fit the temper of its people will not hold. Revolutions occur not only when institutions fail but when the relationship between laws and manners breaks down.

Montesquieu's institutional approach to the prevention of revolution became the blueprint for the American Founders. The Federalists adopted his separation of powers as the structural core of the Constitution, designing a government that would make the question of revolutionary right as nearly academic as possible.

Rousseau radicalizes the right of revolution by grounding it in the concept of the general will. The social contract, as Rousseau conceives it, is not a deal between the people and a ruler. It is an act by which individuals unite into a collective moral body whose sovereign authority is the general will. The government is merely an agent, an "intermediate body" that executes the sovereign's commands. When the government usurps sovereignty, when it substitutes its own particular will for the general will, the social pact is dissolved and the people return to their natural liberty.

This dissolution is not a catastrophe but a reclaiming. In Book III of The Social Contract, Rousseau argues that every government tends naturally toward degeneration: it concentrates power, serves its own interests, and gradually separates itself from the people it was created to serve. Periodic assemblies in which the people reaffirm or withdraw their consent are the proper remedy. Revolution, in this light, is the people's reassertion of a sovereignty they never surrendered, only delegated.

The implications are sweeping. If sovereignty is inalienable and indivisible, if it can never be transferred to a representative, then every government rules on sufferance. Rousseau provides no institutional mechanism (no separation of powers, no checks and balances) to prevent the corruption he describes. The remedy is always the same: the people must act directly. This makes his theory both the most democratic and the most volatile in the tradition.

Rousseau's theory became the philosophical engine of the French Revolution. His insistence that sovereignty belongs to the people as a collective body, not to any institution or representative, gave revolutionary movements a vocabulary they had not possessed before, and a logic whose consequences extended far beyond what Locke had imagined.

The Federalists write as men who have just completed a revolution and are determined to make the next one unnecessary. The Federalist acknowledges the right of revolution, Hamilton states in No. 28 that the people possess an "original right of self-defense" against usurpation, but its entire purpose is to design a government that renders the exercise of that right practically superfluous. The Constitution is, in this sense, a machine for the prevention of revolution.

The key mechanisms are familiar from Montesquieu: separation of powers, checks and balances, federalism. But the Federalists add something new. In Federalist 10, Madison argues that the extended republic, by multiplying factions, prevents any one group from forming a tyrannical majority. In Federalist 43, he defends the provision for constitutional amendment as a controlled channel for the energies that would otherwise seek expression in revolutionary violence. The Constitution can be changed, but only through deliberate, supermajority processes that slow passion and force compromise.

Federalist 51 gives the classic formulation: "If men were angels, no government would be necessary." Since they are not, the structure of government must supply "the defect of better motives." Ambition is set against ambition, interest against interest, branch against branch, state against nation. The result is a system that absorbs political conflict without breaking. Revolution remains a theoretical right, but the Constitution's design is intended to ensure that the conditions requiring it never arise.

The Federalists' achievement was to translate the philosophical right of revolution into constitutional engineering. The tension they leave open is whether constitutional design can truly displace the conditions that produce revolution, or whether it merely channels them. Marx will argue that it cannot: as long as the economic foundations remain unchanged, no constitutional structure will prevent the class conflict that drives history forward regardless of the institutional forms built above it.

Marx transforms revolution from a political right into a historical necessity. The Communist Manifesto opens with the declaration that "the history of all hitherto existing society is the history of class struggles." Freeman and slave, lord and serf, bourgeois and proletarian: in every epoch, an oppressing class and an oppressed class stand in constant opposition. Political revolutions are the surface expression of deeper economic transformations. When the productive forces of a society outgrow the relations of production that contain them, the old order shatters.

The bourgeois revolution, which overthrew feudalism and established capitalist society, was itself progressive in its time. It "created more massive and more colossal productive forces than have all preceding generations together." But capitalism generates its own gravedigger: the proletariat, a class that owns nothing but its labor power and has no stake in the existing order. As capital concentrates and the working class grows, the contradictions of capitalism become unbearable. The proletarian revolution differs from all previous revolutions in that it does not replace one ruling class with another. It abolishes class distinctions altogether.

In Capital, Marx traces the historical process by which capitalism was born through "primitive accumulation," the violent expropriation of peasants from their land, enclosure of the commons, colonial plunder. The system that presents itself as the natural order of things was itself founded on revolutionary violence. The proletarian revolution is the negation of that negation, the expropriation of the expropriators.

Marx closes the tradition's debate on revolution by claiming to have made it scientific. But the question he cannot answer from within his own framework is why the proletariat, whose class interest points toward revolution, so rarely acts on it — why, that is, ideology is so effective at binding people to a system that exploits them. That question, which Marx names but defers, is the one the twentieth century will argue about most bitterly.
