Based on the latest research in philosophy and physics, this collection of original essays by eminent philosophers proposes novel answers to complex questions. Why does time seem to flow in one direction? Can we influence the past? Is only the present real? Does relativity conflict with our common understanding of time? Could science do away with time? These questions and others about time are among the most puzzling problems in philosophy and science.
