Robert Kraynak offers a radical reinterpretation of the political thought of Thomas Hobbes and a new assessment of Hobbes's contribution to the origins and problems of modernity. The author argues that it is necessary to examine a neglected facet of Hobbes's thought—his writings on history, especially Behemoth, his lengthy study of the English Civil War. Through a close reading of these works, Kraynak shows how Hobbes came to consider the possibility of a new kind of political science, one that is supremely confident of the power of critical reason to overcome the authorities of the past to build a new form of civilization yet uncertain about reason's foundations.
