This Book
The Social Contract, Or Principles of Political Right by Jean-Jacques Rousseau, is the book in which Rousseau theorized about the best way in which to set up a political community in the face of the problems of commercial society which he had already identified in his Discourse on Inequality. The Social Contract was a progressive work that helped inspire political reforms or revolutions in Europe, especially in France. The Social Contract argued against the idea that monarchs were divinely empowered to legislate; as Rousseau asserts, only the people, in the form of the sovereign, have that all powerful right.
