 Josiah Royce (1855–1916) was the leading American proponent of absolute idealism, the metaphysical view (also maintained by G. W. F. Hegel and F. H. Bradley) that all aspects of reality, including those we experience as disconnected or contradictory, are ultimately unified in the thought of a single all-encompassing consciousness. Royce also made original contributions in ethics, philosophy of community, philosophy of religion and logic. His major works include The Religious Aspect of Philosophy (1885), The World and the Individual (1899–1901), The Philosophy of Loyalty (1908), and The Problem of Christianity (1913). Royce’s friendly but longstanding dispute with William James, known as “The Battle of the Absolute,” deeply influenced both philosophers’ thought. In his later works, Royce reconceived his metaphysics as an “absolute pragmatism” grounded in semiotics. This view dispenses with the Absolute Mind of previous idealism and instead characterizes reality as a universe of ideas or signs which occur in a process of being interpreted by an infinite community of minds. These minds, and the community they constitute, may themselves be understood as signs. Royce’s ethics, philosophy of community, philosophy of religion, and logic reflect this metaphysical position.
