Read throughout the world, H. G. Wells was one of the most famous political thinkers of the early twentieth century. During the first half of the 1900s, he elaborated a bold and idiosyncratic cosmopolitan socialist vision. In this article, I offer a new reading of Wells's political thought. I argue that he developed a distinctivepragmatistphilosophical orientation, which he synthesized with his commitments to Darwinian evolutionary theory. His pragmatism had four main components: a nominalist metaphysics; a verificationist theory of truth; a Jamesian “will to believe”; and a conception of philosophy as an intellectual exercise dedicated to improving practice. His political thought was shaped by this philosophical orientation. Wells, I contend, was the most high-profile pragmatist political thinker of the opening decades of the twentieth century. Acknowledging this necessitates a re-evaluation of both Wells and the history of pragmatism.
