Themes & patterns

Rousseau argues that legitimate political authority rests on the 'general will' of the people, which aims at the common good and is distinct from the sum of individual wills, forming the basis of the social contract.

The book posits that society is founded on a voluntary agreement where individuals collectively alienate their natural liberty to the community, creating a sovereign body that protects their civil liberty and equality.

Rousseau identifies liberty and equality as the twin ends of every good legislative system, arguing that civil liberty is achieved through obedience to self-prescribed law, and equality is necessary to prevent dependence and oppression.

The text distinguishes between the sovereign (the people expressing the general will) and the government (an executive body), warning that government tends to degenerate and usurp sovereignty, leading to tyranny or anarchy.

Rousseau systematically refutes arguments for absolute rule and slavery, asserting that no person or people can legitimately alienate their freedom, and that force alone cannot create a right to govern.

The book contrasts the primitive independence of the state of nature with the moral and legal order of civil society, where justice replaces instinct and man gains civil liberty and property rights.

Rousseau introduces the figure of a wise legislator who frames laws suited to a people's character and circumstances, emphasizing that laws must align with natural relations to ensure a stable and lasting constitution.

The text explores the inevitable tendency of governments to degenerate—from democracy to aristocracy to monarchy, and finally to despotism—and the dissolution of the body politic through usurpation of sovereignty.
