While it may seem indisputable that time flows in a linear fashion (from past to future), there are a number of philosophical and physical objections to this notion. In the quest to make sense of this conundrum, philosophers and physicists confront fascinating and irresistible questions such as whether effects can precede causes, and whether one can travel in time. In this book, eleven eminent scholars who stand at the boundary between physics and philosophy attempt to answer these questions. There are chapters by W. Unruh and H. Price on cosmology; A. Leggett, P. Stamp, and S. McCall on quantum theory; M. Barrett, E. Sober, and L. Sklar on thermodynamics, and P. Horwich and J. Earman on time travel. The book will be enjoyed by anyone of a speculative turn of mind fascinated by the puzzle of time.
'This collection of papers is an exemplary case of the beneficial effects of the interaction of philosophers and scientists in a non-polistical setting. It is also the state of the art on the problem of time's arrow ... Anyone working on the problem of the direction of time or the related issues discussed in the various chapters would be well advised to delve into it.' John Collier, British Journal for the Philosophy of Science 'I heartily recommend this collection to anyone, philosopher or scientist interested in the direction of time. Many of the papers make significant contributions to the field, and I found almost all of them quite interesting, I am confident this book will emerge as a standard text in the philosophy of time.' Craig Callender, Canadian Philosophical Reviews
