Oxford Studies in Metaphysics is the forum for the best new work in this flourishing field. Much of the most interesting work in philosophy today is metaphysical in character: this series is a much-needed focus for it. OSM offers a broad view of the subject, featuring not only the traditionally central topics such as existence, identity, modality, time, and causation, but also the rich clusters of metaphysical questions in neighbouring fields, such as philosophy of mind and philosophy of science. Besides independent essays, volumes will often contain a critical essay on a recent book, or a symposium that allows participants to respond to one another's criticisms and questions. This fifth volume is largely focused on the metaphysics of time, with sections on time travel; persistence through time; and time, space, and location. The final section of the volume is devoted to a neglected topic that is starting to attract philosophical attention: the metaphysics of sounds. Anyone who wants to know what's happening in metaphysics can start here.
