"'This work by Stephen Finn turns Hobbes scholarship on its head by arguing that Hobbes's natural philosophy is best understood as a development and elaboration of his political philosophy and not the other way around... Hobbes scholars will find this book penetrating and insightful, even if they disagree with the conclusions of the author. I believe this work is one of the most in-depth studies of Hobbes's thought available in the English speaking world today.' James J. McCartney, Villanova University, PA"
