This volume of new essays brings together leading philosophers to examine what physics, psychology, and cognitive science reveal about one of the deepest questions in metaphysics: does time genuinely pass, and what does temporal experience tell us about reality? Unified by a shared naturalistic methodology, the essays insist that theorising about time must be answerable to empirical science rather than grounded solely in a priori reflection. They engage directly with a range of topics including the passage problem and its rivals, the evidential weight of temporal phenomenology, entropy and the asymmetry of memory, predictive processing models of temporal experience, and the limits of transcendental argument. Taken together, they demonstrate that the naturalistic philosophy of time is not merely a methodological orientation but a genuinely productive research programme. This will be a valuable resource for researchers and graduate students in metaphysics, philosophy of mind, and philosophy of science.
