David Wallace - Böcker

Very Short Introductions: Brilliant, Sharp, InspiringPhilosophy of physics is concerned with the deepest theories of modern physics - notably quantum theory, our theories of space, time and symmetry, and thermal physics - and their strange, even bizarre conceptual implications. A deeper understanding of these theories helps both physics, through pointing the way to new theories and new applications, and philosophy, through seeing how our worldview has to change in the light of what we learn from physics.This Very Short Introduction explores the core topics in philosophy of physics through three key themes. The first - the nature of space, time, and motion - begins by considering the philosophical puzzles that led Isaac Newton to propose the existence of absolute space, and then discusses how those puzzles change - but do not disappear - in the context of the revolutions in our understanding of space and time that came first from special, and then from general, relativity. The second - the emergence of irreversible behavior in statistical mechanics - considers how the microscopic laws of physics, which know of no distinction between past and future, can be compatible with the melting of ice, the cooling of coffee, the passing of youth, and all the other ways in which the large-scale world distinguishes past from future. The last section discusses quantum theory - the foundation of most of modern physics, yet mysterious to this day. It explains just why quantum theory is so difficult to make sense of, how we might nonetheless attempt to do it, and why the question has been highly relevant to the development of physics, and continues to be so.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

The Emergent Multiverse presents a striking new account of the 'many worlds' approach to quantum theory. The point of science, it is generally accepted, is to tell us how the world works and what it is like. But quantum theory seems to fail to do this: taken literally as a theory of the world, it seems to make crazy claims: particles are in two places at once; cats are alive and dead at the same time. So physicists and philosophers have often been led either to give up on the idea that quantum theory describes reality, or to modify or augment the theory. The Everett interpretation of quantum mechanics takes the apparent craziness seriously, and asks, 'what would it be like if particles really were in two places at once, if cats really were alive and dead at the same time'? The answer, it turns out, is that if the world were like that--if it were as quantum theory claims--it would be a world that, at the macroscopic level, was constantly branching into copies--hence the more sensationalist name for the Everett interpretation, the 'many worlds theory'. But really, the interpretation is not sensationalist at all: it simply takes quantum theory seriously, literally, as a description of the world. Once dismissed as absurd, it is now accepted by many physicists as the best way to make coherent sense of quantum theory.David Wallace offers a clear and up-to-date survey of work on the Everett interpretation in physics and in philosophy of science, and at the same time provides a self-contained and thoroughly modern account of it--an account which is accessible to readers who have previously studied quantum theory at undergraduate level, and which will shape the future direction of research by leading experts in the field.

Originally writing over 600 years ago, Geoffrey Chaucer is today enjoying a global renaissance. Why do poets, translators, and audiences from so many cultures, from the mountains of Iran to the islands of Japan, find Chaucer so inspiring? In part this is down to the character and sheer inventiveness of Chaucer's work. At the time Chaucer's writings were not just literary adventures, but also a means of convincing the world that poetry and science, tragedy and astrology, could all be explored through the English language. French was still England's aristocratic language of choice when Chaucer was born; Latin was used for university education, theological discussion, and for burying the dead. Could a hybrid tongue such as English ever generate great writing to compare with French and Latin? Chaucer, miraculously, believed that it could, through gradual expansion of expressiveness and scientific precision. He was never paid to do this; he was valued, rather, as a capable civil servant, regulating the export of wool and the building of seating for royal tournaments. Such experiences, however, fed his writing, leading him to achieve a range of social registers, from noble tragedy to barnyard farce, unrivalled for centuries. His tale-telling geography is vast, his fascination with varieties of religious belief endless, and his desire to voice female experience especially remarkable. Many Chaucerian poets and performers, today, are women. In this Very Short Introduction David Wallace introduces the life, performance, and poetry of Chaucer, and analyses his astonishing and enduring appeal.Previously published in hardback as Geoffrey Chaucer: A New IntroductionABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

This collaborative two-volume literary history of Europe, the first yet attempted, unfolds through ten sequences of places linked by trade, travel, topography, language, pilgrimage, alliance, disease, and artistic exchange. The period covered, 1348-1418, provides deep context for understanding current developments in Europe, particularly as initiated by the destruction and disasters of World War II. We begin with the greatest of all European catastrophes: the 1348 bubonic plague, which killed one person in three. Literary cultures helped speed recovery from this unprecedented 'ground zero' experience, providing solace, distraction, and new ideals to live by. Questions of where Europe begins and ends, then as now, and disputes over whom truly 'belongs' on European soil are explored, if not solved, through writing. A war that would last for a century convulsed much of western Europe. Divisions between Orthodox and Roman Catholic Christianities endured, and in 1378 the West divided again between popes of Avignon and Rome. Arabic literary cultures linked Fes and Granada to Jerusalem and Damascus; Persian and Turkish writings began to flourish south and west of Constantinople; Jewish intellectuals treasured Arabic texts as well as Hebrew writings; Armenian colophons proved unique. From 1414-18 western nations gathered to heal their papal schism while also exchanging literary, humanist, and musical ideas; visitors from the East hoped for commitment to wider European peace. Freed from nation state historiography, as bequeathed by the nineteenth century, these 82 chapters freshly assess the free movement of European literature in all its variety, local peculiarity, and regenerative power.

It takes a strong woman to secure bookish remembrance in future times; to see her life becoming a life. David Wallace explores the lives of four Catholic women - Dorothea of Montau (1347-1394) and Margery Kempe of Lynn (c. 1373-c. 1440); Mary Ward of Yorkshire (1585-1645) and Elizabeth Cary of Drury Lane (c. 1585-1639) and and the fate of their writings. All four shock, surprise, and court historical danger. Dorothea of Montau punishes her body and spends all day in church; eight of her nine neglected children die. Kempe, mother of fourteen, empties whole churches with a piercing cry learned at Jerusalem. Ward, living holily but un-immured, is denounced as an Amazon, a chattering hussy, an Apostolic Virago, and a galloping girl. Cary, having left her husband torturing Catholics in Dublin castle, converts to Roman Catholicism in Irish stables in London. Each of these women is mulier fortis, a strong woman: had she been otherwise, Wallace argues, her life would never have been written. The earliest texts of these lives are mostly near-contemporaneous with the women they represent, but their public reappearances have been partial and episodic, with their own complex histories.The lives of these strong women continue to be rewritten long after this premodern period. Incipient European war determines what Kempe must represent between her first discovery in 1934 and full publication in 1940. Dorothea of Montau, first promoted to counter eastern paganism, becomes a bastion against Bolshevism in the 1930s; her cult's meaning is fought out between Günter Grass and Josef Ratzinger. Cary's Catholic daughters, Benedictine nuns, must write of their mother as if she were a saint. Ward's work is not yet done: her followers, having won the right not to be enclosed, must now enter the closed spaces of Roman clerical power.

What would it mean to apply quantum theory, without restriction and without involving any notion of measurement and state reduction, to the whole universe? What would realism about the quantum state then imply? This book brings together an illustrious team of philosophers and physicists to debate these questions. The contributors broadly agree on the need, or aspiration, for a realist theory that unites micro- and macro-worlds. But they disagree on what this implies. Some argue that if unitary quantum evolution has unrestricted application, and if the quantum state is taken to be something physically real, then this universe emerges from the quantum state as one of countless others, constantly branching in time, all of which are real. The result, they argue, is many worlds quantum theory, also known as the Everett interpretation of quantum mechanics. No other realist interpretation of unitary quantum theory has ever been found.Others argue in reply that this picture of many worlds is in no sense inherent to quantum theory, or fails to make physical sense, or is scientifically inadequate. The stuff of these worlds, what they are made of, is never adequately explained, nor are the worlds precisely defined; ordinary ideas about time and identity over time are compromised; no satisfactory role or substitute for probability can be found in many worlds theories; they can't explain experimental data; anyway, there are attractive realist alternatives to many worlds.Twenty original essays, accompanied by commentaries and discussions, examine these claims and counterclaims in depth. They consider questions of ontology - the existence of worlds; probability - whether and how probability can be related to the branching structure of the quantum state; alternatives to many worlds - whether there are one-world realist interpretations of quantum theory that leave quantum dynamics unchanged; and open questions even given many worlds, including the multiverse concept as it has arisen elsewhere in modern cosmology. A comprehensive introduction lays out the main arguments of the book, which provides a state-of-the-art guide to many worlds quantum theory and its problems.

What does realism about the quantum state imply? What follows when quantum theory is applied without restriction, if need be, to the whole universe? These are the questions which an illustrious team of philosophers and physicists debate in this volume. All the contributors are agreed on realism, and on the need, or the aspiration, for a theory that unites micro- and macroworlds, at least in principle. But the further claim argued by some is that if you allow the Schrödinger equation unrestricted application, supposing the quantum state to be something physically real, then this universe is one of countlessly many others, constantly branching in time, all of which are real. The result is the many worlds theory, also known as the Everett interpretation of quantum mechanics.The contrary claim sees this picture of many worlds as in no sense inherent in quantum mechanics, even when the latter is allowed unrestricted scope and even given that the quantum state itself is something physically real. For this picture of branching worlds fails to make physical sense, let alone common sense, even on its own terms. The status of these worlds, what they are made of, is never adequately explained. Ordinary ideas about time and identity over time become hopelessly compromised. The concept of probability itself is brought into question. This picture of many branching worlds is inchoate, it is a vision, an error. There are realist alternatives to many worlds, some even that preserve the Schrödinger equation unchanged. Twenty specially written essays, accompanied by commentaries and discussions, examine these claims and counterclaims in depth. They focus first on the question of ontology, the existence of worlds (Part 1 and 2), second on the interpretation of probability (Parts 3 and 4), and third on alternatives or additions to many worlds (Parts 5 and 6). The introduction offers a helpful guide to the arguments for the Everett interpretation, particularly as they have been formulated in the last two decades.

In 1962, the philosopher Richard Taylor used six commonly accepted presuppositions to imply that human beings have no control over the future. David Foster Wallace not only took issue with Taylor's method, which, according to him, scrambled the relations of logic, language, and the physical world, but also noted a semantic trick at the heart of Taylor's argument. Fate, Time, and Language presents Wallace's brilliant critique of Taylor's work. Written long before the publication of his fiction and essays, Wallace's thesis reveals his great skepticism of abstract thinking made to function as a negation of something more genuine and real. He was especially suspicious of certain paradigms of thought-the cerebral aestheticism of modernism, the clever gimmickry of postmodernism-that abandoned "the very old traditional human verities that have to do with spirituality and emotion and community." As Wallace rises to meet the challenge to free will presented by Taylor, we witness the developing perspective of this major novelist, along with his struggle to establish solid logical ground for his convictions. This volume, edited by Steven M.Cahn and Maureen Eckert, reproduces Taylor's original article and other works on fatalism cited by Wallace. James Ryerson's introduction connects Wallace's early philosophical work to the themes and explorations of his later fiction, and Jay Garfield supplies a critical biographical epilogue.

This was the first full-scale history of medieval English literature for nearly a century. Thirty-three distinguished contributors offer a collaborative account of literature composed or transmitted in England, Wales, Ireland and Scotland between the Norman conquest and the death of Henry VIII in 1547. The volume has five sections: 'After the Norman Conquest'; 'Writing in the British Isles'; 'Institutional Productions'; 'After the Black Death' and 'Before the Reformation'. It provides information on a vast range of literary texts and the conditions of their production and reception, which will serve both specialists and general readers, and also contains a chronology, full bibliography and a detailed index. This book offers an extensive and vibrant account of the medieval literatures so drastically reconfigured in Tudor England. It will thus prove essential reading for scholars of the Renaissance as well as medievalists, and for historians as well as literary specialists.

The Cambridge Companion to Medieval Women's Writing seeks to recover the lives and particular experiences of medieval women by concentrating on various kinds of texts: the texts they wrote themselves as well as texts that attempted to shape, limit, or expand their lives. The first section investigates the roles traditionally assigned to medieval women (as virgins, widows, and wives); it also considers female childhood and relations between women. The second section explores social spaces, including textuality itself: for every surviving medieval manuscript bespeaks collaborative effort. It considers women as authors, as anchoresses 'dead to the world', and as preachers and teachers in the world staking claims to authority without entering a pulpit. The final section considers the lives and writings of remarkable women, including Marie de France, Heloise, Joan of Arc, Julian of Norwich, Margery Kempe, and female lyricists and romancers whose names are lost, but whose texts survive.

David Wallace's examination of the aims and literary affiliations of Boccaccio's early writings provides an indispensable preface to and context for an informed appraisal of Chaucer's usage of Boccaccio. Previous studies of the relationship between the work of the two poets have tended to consider Chaucer's borrowings without making a thorough study of the traditions which shaped the Italian writer's work. Wallace argues that Boccaccio was not primarily concerned with winning recognition at the Angevin court, but was chiefly concerned with fashioning an identity for himself as an illustrious vernacular author. Chaucer recognised that both the Filostrato and Teseida derived their basic narrative capabilities from popular tradition analogous to that of the English tail-rhyme romance. Following a detailed analysis of Chaucer's translation practice in Troilus and Criseyde, Wallace concludesthat it was Boccaccio's attempt to develop a narrative art occupying the middle ground between popular and illustrious, domestic and European traditions that Chaucer found so uniquely congenial and instructive.

This book, originally published in 1995, examines the evolution of environmental policy in 6 OECD countries. Through numerous examples, it contrasts the widely-varying political and regulatory styles and their consequences for innovation. Two industry-specific case studies provide a transnational perspective on the co-evolution of technology and environmental policy. The book concludes that innovation can be successfully harnessed by setting credible, long-term environmental goals and ensuring that regulatory instruments are grounded in flexibility, dialogue and trust.

This report, first published in 1996, argues that radical changes in industrial organization and its relationship to society tend to arise in rapidly industrializing countries, and that new principles of sustainable production are more likely to bear fruit in developing than in developed countries. The rising tide of investment by multinational firms – who bring managerial, organizational and technological expertise – is a major resource for achieving this. Developing countries could steer such investment towards environmental goals through coherent and comprehensive policies for sustainable development.
