Why is the future so different from the past? Why does the past affect the future and not the other way around? What does quantum mechanics really tell us about the world? In this important and accessible book, Huw Price throws fascinating new light on some of the great mysteries of modern physics, and connects them in a wholly original way. Price begins with the mystery of the arrow of time. Why, for example, does disorder always increase, as required by the second law of thermodynamics? Price shows that, for over a century, most physicists have thought about these problems the wrong way. Misled by the human perspective from within time, which distorts and exaggerates the differences between past and future, they have fallen victim to what Price calls the "double standard fallacy": proposed explanations of the difference between the past and the future turn out to rely on a difference which has been slipped in at the beginning, when the physicists themselves treat the past and future in different ways. To avoid this fallacy, Price argues, we need to overcome our natural tendency to think about the past and the future differently. We need to imagine a point outside time -- an Archimedean "view from nowhen" -- from which to observe time in an unbiased way. Offering a lively criticism of many major modern physicists, including Richard Feynman and Stephen Hawking, Price shows that this fallacy remains common in physics today -- for example, when contemporary cosmologists theorize about the eventual fate of the universe. The "big bang" theory normally assumes that the beginning and end of the universe will be very different. But if we are to avoid the double standard fallacy, we need to consider time symmetrically, and take seriously the possibility that the arrow of time may reverse when the universe recollapses into a "big crunch." Price then turns to the greatest mystery of modern physics, the meaning of quantum theory. He argues that in missing the Archimedean viewpoint, modern physics has missed a radical and attractive solution to many of the apparent paradoxes of quantum physics. Many consequences of quantum theory appear counterintuitive, such as Schrodinger's Cat, whose condition seems undetermined until observed, and Bell's Theorem, which suggests a spooky "nonlocality," where events happening simultaneously in different places seem to affect each other directly. Price shows that these paradoxes can be avoided by allowing that at the quantum level the future does, indeed, affect the past. This demystifies nonlocality, and supports Einstein's unpopular intuition that quantum theory describes an objective world, existing independently of human observers: the Cat is alive or dead, even when nobody looks. So interpreted, Price argues, quantum mechanics is simply the kind of theory we ought to have expected in microphysics -- from the symmetric standpoint. Time's Arrow and Archimedes' Point presents an innovative and controversial view of time and contemporary physics. In this exciting book, Price urges physicists, philosophers, and anyone who has ever pondered the mysteries of time to look at the world from the fresh perspective of Archimedes' Point and gain a deeper understanding of ourselves, the universe around us, and our own place in time.

This volume brings together fourteen major essays by one of contemporary philosophy's most challenging thinkers. Huw Price links themes from Quine, Carnap, Wittgenstein and Rorty, to craft a powerful critique of contemporary naturalistic metaphysics. He offers a new positive program for philosophy, cast from a pragmatist mould.

In Your Brain Is a Time Machine, leading neuroscientist Dean Buonomano embarks on an "immensely engaging" exploration of how time works inside the brain (Barbara Kiser, Nature). The human brain, he argues, is a complex system that not only tells time, but creates it; it constructs our sense of chronological movement and enables "mental time travel"--simulations of future and past events. These functions are essential not only to our daily lives but to the evolution of the human race: without the ability to anticipate the future, mankind would never have crafted tools or invented agriculture. This virtuosic work of popular science will lead you to a revelation as strange as it is true: your brain is, at its core, a time machine.

Expressivism Pragmatism And Representationalism

Pragmatists have traditionally been enemies of representationalism but friends of naturalism, when naturalism is understood to pertain to human subjects, in the sense of Hume and Nietzsche. In this volume Huw Price presents his distinctive version of this traditional combination, as delivered in his René Descartes Lectures at Tilburg University in 2008. Price contrasts his view with other contemporary forms of philosophical naturalism, comparing it with other pragmatist and neo-pragmatist views such as those of Robert Brandom and Simon Blackburn. Linking their different 'expressivist' programmes, Price argues for a radical global expressivism that combines key elements from both. With Paul Horwich and Michael Williams, Brandom and Blackburn respond to Price in new essays. Price replies in the closing essay, emphasising links between his views and those of Wilfrid Sellars. The volume will be of great interest to advanced students of philosophy of language and metaphysics.

An enjoyable and compelling ride through one of life’s most fascinating enigmas “What, then, is time? If no one ask of me, I know,” St. Augustine of Hippo lamented. “But if I wish to explain to him who asks, I know not.” Who wouldn’t sympathize with Augustine’s dilemma? Time is at once intimately familiar and yet deeply mysterious. It is thoroughly intangible: We say it flows like a river — yet when we try to examine that flow, the river seems reduced to a mirage. No wonder philosophers, poets, and scientists have grappled with the idea of time for centuries. The enigma of time has also captivated science journalist Dan Falk, who sets off on an intellectual journey In Search of Time. The quest takes him from the ancient observatories of stone-age Ireland and England to the atomic clocks of the U.S. Naval Observatory; from the layers of geological “deep time” in an Arizona canyon to Albert Einstein’s apartment in Switzerland. Along the way he talks to scientists and scholars from California to New York, from Toronto to Oxford. He speaks with anthropologists and historians about our deep desire to track time’s cycles; he talks to psychologists and neuroscientists about the mysteries of memory; he quizzes astronomers about the beginning and end of time. Not to mention our latest theories about time travel — and the paradoxes it seems to entail. We meet great minds from Aristotle to Kant, from Newton to Einstein — and we hear from today’s most profound thinkers: Roger Penrose, Paul Davies, Julian Barbour, David Deutsch, Lee Smolin, and many more. As usual, Dan Falk’s style combines exhaustive research with a lively, accessible, and often humorous style, making In Search of Time a delightful tour through a most curious dimension.
