What is the social contract? A citizen`s agreement with the government? No, it would just mean the continuation of [Roussau`s] idea. The social contract is a man`s agreement with man; An agreement that must follow through on what we call society. In this one, the notion of communist justice, first presented by the primitive fact of the exchange, … is replaced by that of fair distribution … These words, these treaties, communal justice, which are the language of the law, to translate into the language of the economy, and you have trade, that is, in their utmost importance, the action by which man and man declare themselves essentially producers, and abdicate all the advantages to govern each other. The social contract was considered an “event” in which individuals came together and some of their individual rights were ceded so that others would delece up their rights.  This led to the creation of the state, a sovereign entity, as individuals were today under their rule, which would create laws to regulate social interactions. Human life is no longer “a war of all against all.” A social contract is an unofficial agreement, shared by all in a society where they renounce a certain freedom for security. You say that it is naturally good to do injustice; To suffer injustice, evil; but that evil is greater than good. And if people have done wrong and suffered wrongs and experienced both, have not been able to avoid one and get the other, they think they better agree with each other that they have neither; As a result, laws and mutual alliances are emerging; and what is ordered by law is described by them as legitimate and just. They confirm it as the origin and nature of justice; – it is one way or another, between the best of all, which is to do injustice and not be punished, and the worst of all which is to suffer injustice without the power of retaliation; and justice, which is at the centre of both, is not tolerated as a good, but as a lesser evil and honored by the inability of men to do harm.
For no one worthy of being called a human being would ever submit to such an arrangement if he could resist; He would be crazy if he did. This is the Socrates report on the nature and origin of justice.  Quentin Skinner argued that several critical modern innovations in contract theory are found in the writings of French Calvinists and Huguenots, whose work was in turn led by writers in the Netherlands who opposed their submission to Spain and later to Catholics in England.  Francisco Suarez (1548-1617), of the Salamanca school, could be considered a former social contract theorist, who theorized natural law by trying to limit the divine right of absolute monarchy. All these groups have been led to articulate conceptions of popular sovereignty through a confederation or social treaty, and all these arguments began with proto-“State of Nature” arguments that the basis of the policy is that everyone is inherently free from submission to any government. The theory of the social contract also appears in Crito, another dialogue of Plato. Over time, the theory of the social contract became more and more widespread, after Epicurus (341-270 BC), the first philosopher, who regarded justice as a social contract and which did not exist in nature because of divine intervention (see below and also epicurean ethics), decided to place theory at the top of his society.
