Social Contract Theory
The Enlightenment political theory that legitimate government rests not on divine right or force but on an implicit agreement between citizens and rulers: citizens surrender some freedoms in exchange for protection of their natural rights. The three competing versions, Hobbes, Locke, and Rousseau, produce radically different political conclusions.
Social contract theory was the dominant Enlightenment framework for justifying political authority without appealing to God or tradition. The core idea: individuals in a 'state of nature' (without government) rationally choose to surrender some freedoms to a sovereign authority in exchange for protection of their remaining rights. The terms of this hypothetical agreement determine the legitimate limits of government power.
Thomas Hobbes (Leviathan, 1651): the state of nature is a 'war of all against all', life is 'solitary, poor, nasty, brutish, and short.' Rational individuals surrender almost all freedoms to an absolute sovereign (the Leviathan) in exchange for peace and security. The sovereign's authority is near-unlimited because any government, however bad, is better than the alternative. Hobbes justifies strong, centralized authority.
John Locke (Second Treatise, 1689): the state of nature is not war but inconvenience, peaceful but lacking enforcement of natural rights (life, liberty, property). The contract is limited: citizens surrender only enforcement rights to a government that is obligated to protect natural rights. Government that violates these rights forfeits its legitimacy; citizens retain the right of revolution. Locke directly inspired the American Declaration of Independence.
Jean-Jacques Rousseau (Social Contract, 1762): the contract must reflect the 'general will', not the sum of individual preferences but what is genuinely best for the collective. Rousseau distrusts private property and inequality as corruptions of natural human goodness. His theory leans collectivist and suspicious of representative institutions, influencing the French Revolution's radical egalitarianism.
Application: the US founding documents (Declaration of Independence, Constitution) are essentially Lockean social contract documents. The ongoing debate about government's proper scope (protecting individual rights vs. serving collective welfare) maps onto the Locke vs. Rousseau tension.

Frequently asked questions
What are the three main social contract theories? ＋
Hobbes: state of nature is brutal war; we surrender almost all freedoms to an absolute sovereign for peace. Locke: state of nature is inconvenient but peaceful; we surrender only enforcement rights to a limited government obligated to protect life, liberty, and property, with a right of revolution if it fails. Rousseau: the contract must reflect the general will (collective good, not individual preferences); private property and inequality corrupt natural human goodness.
How did social contract theory influence the American founding? ＋
The Declaration of Independence is almost directly Lockean: 'We hold these truths to be self-evident, that all men are created equal, endowed with unalienable rights, Life, Liberty, and the pursuit of Happiness' mirrors Locke's natural rights (life, liberty, property). 'That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or abolish it' is Locke's right of revolution verbatim.
