Abstract
This is the introduction chapter of A Companion to the Philosophy of Time, which tackles the historical development of the philosophy of time. This volume brings together experts in the various branches of the philosophy of time from around the world. Part I of this volume features essays on the philosophy of time from the pre‐Socratic period through the twentieth century. Parts II and III reflect, respectively, on the physics and metaphysics of time, and on the study of the experience of time. Together, Parts II and III address the fundamental question of contemporary time studies: distinguishing between time as it is in itself, and time as humans perceive and experience it; between the scientific and manifest images of time.
