A symposium on Samantha Frost's Lessons from a Materialist Thinker: Hobbesian Reflections on Ethics andPolitics offers an opportunity to revisit one of the most original contributions to Hobbes scholarship in the last few decades. The book's originality resides not only in recuperating Hobbes's materialist metaphysics for contemporary ethics and politics, but in making Hobbes's take on matter inform novel conceptual approaches to social and non-social reality, such as new materialism- a philosophical school that conceives matter as vibrant and agentic, rather than inert.
