Together, Pierre Dardot and Chrisitan Laval are one of the great intellectual partnerships of our time. In this exhaustive account, they show how the common has become the defining principle of alternative political movements in the 21st century. In a feat of analytic clarity, Dardot and Laval dissect and synthesize a vast repository on the concept of the commons, from the fields of philosophy, political theory, economics, legal theory, history, theology, and sociology.
