Book Description
"How do we know what happened in the past? We cannot go back, and no amount of historical data can enable us to understand with absolute certainty what life was like then. It is easy to demolish the very idea of historical knowing, but it is impossible to demolish the importance of historical knowing. In an age of cable television pundits and anonymous bloggers dueling over history, the value of owning history increases at the same time as our confidence in history as a way of knowing crumbles. Historical knowledge thus presents a paradox - the more it is required, the less reliable it has become. To reconcile this paradox - that history is impossible but necessary - Peter Charles Hoffer proposes a practical, workable philosophy of history for our times, one that is robust and realistic, and that speaks to anyone who reads, writes and teaches history. The philosophy of history that Hoffer supports in The Historians' Paradox is driven by a continual and careful search for the authentic, but without confining the real to a finite or closed set of facts. Hoffer urges us to think and live with a keen awareness that history is everywhere, to accept the impossibility of measuring its reliability, but to never approach it unquestioningly. Covering a sweeping range of philosophies (from ancient history to game theory), methodological approaches to writing history, and the advantages and disadvantages of different strategies of argument, Hoffer constructs a philosophy of history that is reasonable, free of fallacy, and supported by appropriate evidence that is itself tenable. The Historians' Paradox brings together accounts of actual historical events, anecdotes about historians, insights from philosophers of history, and the personal experience of a long time scholar and teacher. Throughout, Hoffer liberally spices the mixture with humor to create a philosophy of history for our times."--publisher.

A Brief History of the Paradox
Author: Roy Sorensen
Publisher: Oxford University Press
ISBN: 0199728577
Category : Philosophy
Languages : en
Pages : 413
Book Description
Can God create a stone too heavy for him to lift? Can time have a beginning? Which came first, the chicken or the egg? Riddles, paradoxes, conundrums--for millennia the human mind has found such knotty logical problems both perplexing and irresistible. Now Roy Sorensen offers the first narrative history of paradoxes, a fascinating and eye-opening account that extends from the ancient Greeks, through the Middle Ages, the Enlightenment, and into the twentieth century. When Augustine asked what God was doing before He made the world, he was told: "Preparing hell for people who ask questions like that." A Brief History of the Paradox takes a close look at "questions like that" and the philosophers who have asked them, beginning with the folk riddles that inspired Anaximander to erect the first metaphysical system and ending with such thinkers as Lewis Carroll, Ludwig Wittgenstein, and W.V. Quine. Organized chronologically, the book is divided into twenty-four chapters, each of which pairs a philosopher with a major paradox, allowing for extended consideration and putting a human face on the strategies that have been taken toward these puzzles. Readers get to follow the minds of Zeno, Socrates, Aquinas, Ockham, Pascal, Kant, Hegel, and many other major philosophers deep inside the tangles of paradox, looking for, and sometimes finding, a way out. Filled with illuminating anecdotes and vividly written, A Brief History of the Paradox will appeal to anyone who finds trying to answer unanswerable questions a paradoxically pleasant endeavor.

People of Paradox
Author: Terryl L. Givens
Publisher: Oxford University Press
ISBN: 0198037368
Category : Religion
Languages : en
Pages : 433
Book Description
In People of Paradox, Terryl Givens traces the rise and development of Mormon culture from the days of Joseph Smith in upstate New York, through Brigham Young's founding of the Territory of Deseret on the shores of Great Salt Lake, to the spread of the Latter-Day Saints around the globe. Throughout the last century and a half, Givens notes, distinctive traditions have emerged among the Latter-Day Saints, shaped by dynamic tensions--or paradoxes--that give Mormon cultural expression much of its vitality. Here is a religion shaped by a rigid authoritarian hierarchy and radical individualism; by prophetic certainty and a celebration of learning and intellectual investigation; by existence in exile and a yearning for integration and acceptance by the larger world. Givens divides Mormon history into two periods, separated by the renunciation of polygamy in 1890. In each, he explores the life of the mind, the emphasis on education, the importance of architecture and urban planning (so apparent in Salt Lake City and Mormon temples around the world), and Mormon accomplishments in music and dance, theater, film, literature, and the visual arts. He situates such cultural practices in the context of the society of the larger nation and, in more recent years, the world. Today, he observes, only fourteen percent of Mormon believers live in the United States. Mormonism has never been more prominent in public life. But there is a rich inner life beneath the public surface, one deftly captured in this sympathetic, nuanced account by a leading authority on Mormon history and thought.

The Paradox of Tar Heel Politics
Author: Rob Christensen
Publisher: Univ of North Carolina Press
ISBN: 0807899631
Category : History
Languages : en
Pages : 372
Book Description
How can a state be represented by Jesse Helms and John Edwards at the same time? Journalist Rob Christensen answers that question and navigates a century of political history in North Carolina, one of the most politically vibrant and competitive southern states, where neither conservatives nor liberals, Democrats nor Republicans, have been able to rest easy. It is this climate of competition and challenge, Christensen argues, that enabled North Carolina to rise from poverty in the nineteenth century to become a leader in research, education, and banking in the twentieth. In this new paperback edition, Christensen provides updated coverage of recent changes in North Carolina's political landscape, including the scandals surrounding John Edwards and Mike Easley, the defeat of U.S. senator Elizabeth Dole, the election of the state's first woman governor, and voters' approval of an African American candidate for president. The book provides an overview of the run-up to the 2010 elections and explains how North Carolina has become, arguably, the most politically competitive state in the South.

The American Paradox
Author: Steven M. Gillon
Publisher: Wadsworth Publishing Company
ISBN: 9780618660865
Category : History
Languages : en
Pages : 480
Book Description
This narrative text for courses in recent American history emphasizes political participation and popular culture. Its main theme is the relationship of Americans to their government—for example, how Americans as a people remain skeptical of big government even as they expect it to facilitate large programs such as Social Security. The Second Edition features a range of content enhancements, including increased coverage of events from 1970 to the present. In addition to the author's vivid, accessible writing style, the text maintains its focus on the tension between popular culture and social realities, the dynamics of minority groups and their place in American society, and the ambivalent feelings of many Americans concerning the U.S.'s role in the world during the postwar period. New! Coverage of the 1960s has been reorganized to include separate chapters on the Great Society and Vietnam. These new chapters bring clarity to a chaotic decade. New! The author has included more coverage of women—particularly their role in the rise of the New Left and in the development of Feminism—and more information about U.S. involvement in the Middle East as a foundation for understanding the war on terrorism. New! Each chapter contains up to three primary sources. New documents include excerpts from Betty Friedan's The Feminine Mystique; Martin Luther King, Jr.'s Montgomery bus boycott speech; and excerpts from the 9/11 Commission's final report. Unlike most postwar American history books that tend to emphasize the 50s and 60s, The American Paradox includes extensive coverage of the 1960s to the present.

Plagues and the Paradox of Progress
Author: Thomas J. Bollyky
Publisher: MIT Press
ISBN: 0262038455
Category : Medical
Languages : en
Pages : 277
Book Description
Why the news about the global decline of infectious diseases is not all good. Plagues and parasites have played a central role in world affairs, shaping the evolution of the modern state, the growth of cities, and the disparate fortunes of national economies. This book tells that story, but it is not about the resurgence of pestilence. It is the story of its decline. For the first time in recorded history, virus, bacteria, and other infectious diseases are not the leading cause of death or disability in any region of the world. People are living longer, and fewer mothers are giving birth to many children in the hopes that some might survive. And yet, the news is not all good. Recent reductions in infectious disease have not been accompanied by the same improvements in income, job opportunities, and governance that occurred with these changes in wealthier countries decades ago. There have also been unintended consequences. In this book, Thomas Bollyky explores the paradox in our fight against infectious disease: the world is getting healthier in ways that should make us worry. Bollyky interweaves a grand historical narrative about the rise and fall of plagues in human societies with contemporary case studies of the consequences. Bollyky visits Dhaka—one of the most densely populated places on the planet—to show how low-cost health tools helped enable the phenomenon of poor world megacities. He visits China and Kenya to illustrate how dramatic declines in plagues have affected national economies. Bollyky traces the role of infectious disease in the migrations from Ireland before the potato famine and to Europe from Africa and elsewhere today. Historic health achievements are remaking a world that is both worrisome and full of opportunities. Whether the peril or promise of that progress prevails, Bollyky explains, depends on what we do next. A Council on Foreign Relations Book

The PKU Paradox
Author: Diane B. Paul
Publisher: JHU Press
ISBN: 1421411318
Category : Medical
Languages : en
Pages : 316
Book Description
Named one of the "Ten must-read science histories" by Science Magazine In a lifetime of practice, most physicians will never encounter a single case of PKU. Yet every physician in the industrialized world learns about the disease in medical school and, since the early 1960s, the newborn heel stick test for PKU has been mandatory in many countries. Diane B. Paul and Jeffrey P. Brosco’s beautifully written book explains this paradox. PKU (phenylketonuria) is a genetic disorder that causes severe cognitive impairment if it is not detected and treated with a strict and difficult diet. Programs to detect PKU and start treatment early are deservedly considered a public health success story. Some have traded on this success to urge expanded newborn screening, defend basic research in genetics, and confront proponents of genetic determinism. In this context, treatment for PKU is typically represented as a simple matter of adhering to a low-phenylalanine diet. In reality, the challenges of living with PKU are daunting. In this first general history of PKU, a historian and a pediatrician explore how a rare genetic disease became the object of an unprecedented system for routine testing. The PKU Paradox is informed by interviews with scientists, clinicians, policymakers, and individuals who live with the disease. The questions it raises touch on ongoing controversies about newborn screening and what happens to blood samples collected at birth.
