A social contact is an implicit agreement among the members of a society to cooperate for social benefits, for example by sacrificing some individual freedom for state protection. Theories of a social contract became popular in the 16th, 17th, and 18th centuries among theorists such as Thomas Hobbes, John Locke, and Jean-Jacques Rousseau, as a means of explaining the origin of government and the obligations of subjects.
Interestingly enough. In France, the definition of freedom contains “my freedom ends where the freedom of others begins”. Freedom is therefore a social contract held by boundaries, as opposed to the individualist unbridled freedom from the USA.
