The meaning of ‘moderate enlightenment’ has been monopolised by Jonathan Israel. In this guise, ‘moderate enlightenment’ is built atop a compromise between authority and innovation, between reason and revelation, and amounts to an intellectually subordinate counterpart to the Radical Enlightenment. This ‘negative’ definition obstructs serious interpretation of what ‘moderate enlightenment’ can mean. This essay progresses instead an enquiry into a ‘positive’ definition of ‘moderate enlightenment’ – an enlightenment defined by moderation. It does so by surveying key lineaments within a century (...) of historiography on the enlightenment, from the 1920s to the present. It focuses on the contributions to that historiography by two titanic figures of twentieth-century scholarship and political thought: Leo Strauss and J.G.A. Pocock. Strauss and Pocock are shown to have advanced equally substantive, if fundamentally distinct, concepts of ‘moderate enlightenment’. Searching for ‘moderate enlightenment’, aided by Strauss and Pocock, raises new vistas in both eighteenth century intellectual history and twentieth century historiography – and the pertinence of both for the history of political thought. It also brings into question the political-philosophical substance of the ‘moderation’ which underpins a positively defined ‘moderate enlightenment’. (shrink)
