But the state system born of the social contract was also anarchic (without direction). Just as individuals were sovereign in the state of nature and thus let themselves be guided by their own interests and by the absence of rights, States now act in their own interest in competition. Thus, like the state of nature, states had inevitably come into conflict because there was no sovereign who went beyond the (more powerful) state, capable of imposing on everyone a system such as the laws on social contracts by force. In fact, Hobbes`s work served as the basis for the theories of realism advanced by E. H. Carr and Hans Morgenthau. Hobbes wrote in Leviathan that people (“we”) need the “terrour of a certain power,” otherwise people will not respect the law of reciprocity, “(on the whole) do to others as we would.”  While M is deliberative; rules, principles or institutions R; I the (hypothetical) people in the original position or the state of nature who enter into the social contract; and I are the individuals in the real world who follow the social contract.  Pierre-Joseph Proudhon (1809-1865) favours a conception of social treaties that does not imply that one individual hands over sovereignty to others. According to him, the social contract did not exist between individuals and the state, but between individuals who did not impose or govern each other, each retaining full sovereignty over himself: the concept of social contract was originally laid down by Glaucon, as Plato described in the Republic, Book II. 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.” John Locke`s conception of the social contract was fundamentally different from Hobbes`s, for only the central idea that people in a state of nature would willingly come together to form a state was maintained.
