In Hobbes’ Kingdom of Light, Devin Stauffer argues that Hobbes was engaged in a struggle on multiple fronts against forces, both philosophic and religious, that he thought had long distorted philosophy and destroyed the prospects of a lasting peace in politics. By exploring the twists and turns of Hobbes’s arguments, not only in his famous Leviathan but throughout his corpus, Stauffer uncovers the details of Hobbes’ critique of an older outlook, rooted in classical philosophy and Christian theology, and reveals the complexity of Hobbes’s war against the “Kingdom of Darkness.”
