Hugo Grotius

Hugo Grotius appears as a major theorist of political authority whose arguments give Jean-Jacques Rousseau a recurring test case: can a fact such as conquest, obedience, or enslavement establish a right to rule? The account places Grotius within the history of social-contract theory, then follows Rousseau’s objections to the use of force and submission as foundations of legitimate government. Its portrait is therefore less a biography than an intellectual and political critique, attentive both to the reasoning attributed to Grotius and to the circumstances in which his arguments were advanced.

Place in Social-Contract Theory

The account distinguishes two broad forms of social-contract theory. In the first, society rests on an agreement between a people and its government; in the second, it originates in an agreement among the individuals who compose it. The first form has medieval roots and appears in political writing from the sixteenth century into the seventeenth. Grotius belongs to this history, though his position is not always straightforward: his work has sometimes been read as admitting both forms, while the account argues that he is thinking of a contract between people and government that can authorize either democratic or monarchical rule.

That distinction matters because the first form could support opposing political claims. A contract might be interpreted as surrendering the people’s freedom once and for all, or, as theologian-lawyers more commonly maintained, as imposing reciprocal obligations on the ruler. Under the latter view, the people could appeal to the agreement to demand constitutional government. The account compares this appeal with earlier demands that rulers respect the established customs of the realm, and identifies the 1689 Convention Parliament’s charge against James II as a clear later instance: it accused him of breaking the original contract between king and people. Rousseau’s refutation, set out in the third book of The Social Contract and also directed in part at Thomas Hobbes, challenges this first form of contract.

A different theory makes the agreement one among individuals forming a society. This version appears in varying forms in Richard Hooker, John Milton, Hobbes, John Locke, and Rousseau. Its best-known practical expression, as the account presents it, is the Mayflower declaration of 1620, in which its signers covenant to form themselves into a civil body politic. Such an agreement seems to lead naturally to popular sovereignty, but before Rousseau it had also supported conflicting political views. The distinction between the two theories is thus not merely historical: it determines whether a contract is understood as an exchange between rulers and ruled or as the act by which the people itself is constituted.

Fact, Force, and Political Right

Rousseau’s disagreement with Grotius rests on a methodological distinction. The Social Contract does not set out to describe the actual institutions of existing states in the manner associated with Montesquieu; it seeks principles that can ground every legitimate society. Historical facts may inform political inquiry, but, in Rousseau’s formulation, they cannot by themselves create a right. The account accordingly characterizes Grotius’s habitual reasoning as establishing right by fact, a method it regards as especially favorable to tyrants.

The objection becomes sharper in Rousseau’s examination of force. If strength creates right, then a stronger power can always inherit the supposed right of the one it defeats. Whenever disobedience becomes possible without penalty, the defeated authority loses its claim, leaving strength—not obligation—as the only operative standard. On this account, calling submission a duty adds nothing to the fact of compulsion. Grotius’s arguments matter here because they exemplify the danger Rousseau sees in moving from what has happened to what is justified: political obedience cannot be made legitimate merely by pointing to the power that secured it.

Submission, Slavery, and War

Grotius’s comparison between an individual who may alienate his liberty and a people that may submit to a king is one of Rousseau’s principal targets. Rousseau asks what a people could receive in exchange for surrendering itself. A ruler does not provide for subjects from an independent source; the ruler’s support comes from them. Nor does a promise of tranquillity settle the matter, since a government’s wars, demands, and ministers may burden its subjects more heavily than the conflicts from which it claims to protect them. Quiet alone cannot establish the justice of a political arrangement.

Rousseau extends the argument across generations. Even if an individual could surrender his own liberty, he could not irrevocably surrender his children’s: they are born free, and their liberty belongs to them. A parent may make arrangements for their preservation before they can decide for themselves, but cannot give them away without conditions. For arbitrary government to be legitimate on this reasoning, each generation would have to remain able to accept or reject it; a government subject to that choice would no longer be arbitrary. The critique therefore treats political submission not as a valid inheritance but as a claim that must continually be justified to those who are governed.

The same dispute reaches the supposed right of slavery through conquest. Grotius and other writers, as Rousseau reports their argument, maintain that a victor entitled to kill the defeated may instead accept their liberty in exchange for sparing their lives; the arrangement is then represented as beneficial to both parties. Rousseau rejects the premise. In his account, people in primitive independence lack the stable relations necessary for a state of war, while in civil society relations fall under law. War is a relation between things, not a natural enmity between persons. Individual combats and duels cannot establish a state of war, and private wars authorized under Louis IX are described as feudal abuses, incompatible with natural right and sound political order. The alleged bargain of conquest therefore cannot supply the legitimate foundation its defenders claim for it.

Political Position and Critical Reception

The account also links Grotius’s argument to the political situation surrounding his work. It describes him as a refugee in France, dissatisfied with his own country and seeking the favor of Louis XIII, to whom his book was dedicated. It accuses him of using elaborate arguments to deprive peoples of rights and assign those rights to kings. His translator Barbeyrac, who dedicated his translation to George I of England, faces a different political difficulty: following the expulsion of James II, which he calls an abdication, he must avoid depicting William as a usurper. The account presents both writers as caught between political principles and the interests their writing might offend.

Its criticism is pointedly institutional as well as philosophical. Had Grotius and Barbeyrac adopted what the account calls the true principles, it argues, their difficulties and inconsistencies would have disappeared; but the result would have been an unwelcome truth for political patrons and a position advantageous only to the people. It underscores this pressure by observing that truth offers no path to ambassadorships, professorships, or pensions from the people. Grotius thus functions in the discussion both as a theorist whose arguments Rousseau contests and as an example of how political dependence can shape the presentation of political right.
