A standard reading of modern political theory, or one could arguably say the standard reading, lays the greatest emphasis upon the state of nature theories and their attendant arguments concerning the social contract. Beginning with Hobbes, this standard reading continues on through Locke and Rousseau, emphasizing along the way the influence of Locke upon Jefferson. Given the revolutions of the late 18th century, especially in light of the social contract justifications given by Jefferson in the Declaration of Independence, it is perhaps not surprising that this has become the standard reading.
What I would like to argue is that it is precisely the importance of the social contract theorists for the intellectuals who sought a justificatory ground for revolution that has resulted in the great stress that has been laid upon this aspect of modern political theory. Lurking beneath this standard reading of political theory we can find a deeper tension at play, and a tension that provides for a more comprehensive and illuminating account of political and economic processes as they have actually unfolded since the late 17th century. This is the tension between the thought of Spinoza and Leibniz.
