He believes in science, but only magic can help his mom. Twelve-year-old Finn is used to people in his family disappearing. His twin sister, Faith, drowned when they were three years old. A few months ago, his mom abandoned him and his dad with no explanation. Finn clings to the concrete facts in his physics books—and to his best friend, Gabi—to ward off his sadness. But then his grandmother tells him a secret: the women in their family are Travelers, able to move back and forth in time. Finn's mom is trapped somewhere in the timeline, and she's left Finn a portal to find her. But to succeed, he'll have to put his trust in something bigger than logic. "This is an incredible book, no matter which time universe you're in. I couldn't put it down. One of my favorite debut novels of the year."—Erin Entrada Kelly, New York Times bestselling author and 2018 Newbery Medal winner

"The most important debate among twentieth-century philosophers of time has been whether events that have happened, are happening, or will happen are equally real (the tenseless theory of time) or whether there is a fundamental distinction between past, present, and future, with only present events possessing full existence (the tensed theory). In the 1980s a new version of the tenseless theory of time emerged. While advocates still posit that all events are equally real, they depart from the old tenseless theory by conceding that tensed expressions cannot be translated into tenseless ones, and support their view of time using other arguments." "This anthology offers the latest turns in the debate over the new theory of time, with essays written by many of the most prominent contemporary thinkers in the philosophy of time. There are discussions on the role - or nonrole - of language in determining which theory is true; McTaggart's paradox and the logical difficulties that defenders of the tenseless theory say are inherent in tensed theory; and the nature of our experience of time, which proponents of both theories claim can now be explained. The Preface and the General Introduction to the book set the debate within the wider philosophical context and show why the subject of temporal becoming is a perennial concern of science, religion, language, logic, and the philosophy of mind."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

"An accessible and engaging exploration of the mysteries of time." -Brian Greene, author of The Elegant Universe Twenty years ago, Stephen Hawking tried to explain time by understanding the Big Bang. Now, Sean Carroll says we need to be more ambitious. One of the leading theoretical physicists of his generation, Carroll delivers a dazzling and paradigm-shifting theory of time's arrow that embraces subjects from entropy to quantum mechanics to time travel to information theory and the meaning of life. From Eternity to Here is no less than the next step toward understanding how we came to exist, and a fantastically approachable read that will appeal to a broad audience of armchair physicists, and anyone who ponders the nature of our world.

Should you care less about your distant future? What about events in your life that have already happened? How should the passage of time affect your planning and assessment of your life? Most of us think it is irrational to ignore the future but completely harmless to dismiss the past. But this book argues that rationality requires temporal neutrality: if you are rational you don't engage in any kind of temporal discounting. The book draws on puzzles about real-life planning to build the case for temporal neutrality. How much should you save for retirement? Does it make sense to cryogenically freeze your brain after death? How much should you ask to be compensated for a past injury? Will climate change make your life meaningless? Meghan Sullivan considers what it is for you to be a person extended over time, how time affects our ability to care about ourselves, and all of the ways that our emotions might bias our rational planning. Drawing substantially from work in social psychology, economics and the history of philosophy, the book offers a systematic new theory of rational planning.

he present book and its companion volume The Tenseless Theory of Time: a T Critical Examination are an attempt to adjudicate what one recent discussant has called "the most fundamental question in the philosophy of time," namely, "whether a static or a dynamic conception of the world is correct. "! I had originally intended to treat this question in the space of a single volume; but the study swelled into two. I found that an adequate appraisal of these two of time requires a wide-ranging discussion of issues in competing theories metaphysics, philosophy of language, phenomenology, philosophy of science, philosophy of space and time, and even philosophy of religion, and that this simply could not be done in one volume. If these volumes succeed in making a contribution to the debate, it will be precisely because of the synoptic nature of the discussion therein. Too often the question of the nature of time has been prematurely answered by some philosopher or physicist simply because he is largely ignorant of relevant discussions outside his chosen field of expertise. In these two complementary but independent volumes I have attempted to appraise what I take to be the most important arguments drawn from a variety of fields for and against each theory of time.
