Oxford Studies in Metaphysics is dedicated to the timely publication of new work in metaphysics, broadly construed. These volumes provide a forum for the best new work in this flourishing field. They offer 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. This book is the sixth volume in the series. It contains essays by Jason Turner, Ross P. Cameron, Gabriel Uzquiano, Raul Saucedo, Elizabeth Barnes and J. Robert G. Williams, Matti Eklund, Richard Woodward, and Rory Madden.
