De Cive is the first full expositon of the political thought of Thomas Hobbes,the greatest English political philosper.Professors Tuck and Siverthorne have undertaken the first complete translation sice 1651,a rendition long thought to be at least sanctioned by Hobbes himself.

On the Citizen is written in a clear,straightforward,expository style,and in many ways offers students a more digestible account of Hobbes's political thought than the Leviathan itself.This new transltaion is both accurate and accessible,and is itself a significant schology,a bebliography and an expository introduction.Throughout,the editors have emphasized consistency in the translation and usage of Hobbes's basic conceptual vocabulary,trspceting Hobbes's own concern for accurate definition of tens.
