What is the one thelse beliefs of social contract theory?

The essence of the theory is believed to be the following: to live in society, human beings agree to an implicit social contract, which grants them certain rights in exchange for abandoning the complete freedom they would have in a state of nature. Thus, the rights and duties of individuals constitute the clauses of the social contract. The State is the entity created to enforce the contract. Similarly, those who sign it can change the terms of the contract if they wish; rights and duties are not immutable or natural. On the other hand, a greater number of rights implies greater duties; and less rights, less duties.
