This thesis attempts to articulate how Rousseau’s implicit view of history deeply influenced his perspective towards the General Will and the Legislator, through the way he defended the “coherent system” for the consistency of his texts. In this thesis, I contend that the aim of both The Social Contract and The Second Discourse is to resolve the inevitable corruption in the history of human nature. Specifically speaking, the main idea of The Social Contract is to overcome the false contract emerged in history development described in the Second Discourse. In addition, the role of Legislator is to direct the self-enslaved social men to become the citizens who are able to establish Social Contract on their own. Finally, I conclude that in the reforming projects for Geneva, Poland and Corsica, as a legislator, Rousseau provides the remedy for certain social impediment, based on his judgment of history.
