In The Social Contract, Rousseau establishes that a “just” social organization is based on a pact guaranteeing equality and freedom between all citizens. This pact is contracted between all the participants, that is to say the exhaustive set of citizens. In the social compact, everyone gives up their natural freedom to gain civil freedom. Popular sovereignty is the fundamental principle of the social contract. The indivisibility of this sovereignty is another fundamental principle, by which it must be understood that the power of the Sovereign cannot be divided (Rousseau uses this term to designate the sovereign people) and he cannot separate himself from it by particular interest, because particular interest is contrary to the search for the general interest, the only objective of the social contract. Rousseau sees this social contract as following the state of nature in which the right of the strongest reigns.
