In 1998 I left everything I'd ever known behind and began a journey that would last a lifetime.I strapped on a backpack and hit the road with no particular destination in mind. I was looking for something that made sense in a world of confusion and lies. I wanted to witness a different perspective on life and find somewhere to belong. From the gutters of New Orleans to the mountains of Colorado, and beyond, an unexplicable desire forced me to keep a detailed journal of the events that transpied. This is that journal. Heralded as "On the Road' for the New Millenium" by Daniel Quinn, best-selling author of Ishmael.
This two-volume collection of folktales represents some of the finest examples of American oral tradition. Drawn from the largest archive of American folk culture, the American Folklife Center at the Library of Congress, this set comprises magic tales, legends, jokes, tall tales and personal narratives, many of which have never been transcribed before, much less published, in a sweeping survey. Eminent folklorist and award-winning author Carl Lindahl selected and transcribed over 200 recording sessions - many from the 1920s and 1930s - that span the 20th century, including recent material drawn from the September 11 Project. Included in this varied collection are over 200 tales organized in chapters by storyteller, tale type or region, and representing diverse American cultures, from Appalachia and the Midwest to Native American and Latino traditions. Each chapter begins by discussing the storytellers and their oral traditions before presenting and introducing each tale, making this collection accessible to high school students, general readers or scholars.
Drawing on a deep understanding of the shades and structures of the blues, Steven C. Tracy elucidates the vital relationship between this musical form and the art of Langston Hughes, preeminent poet of the Harlem Renaissance. Tracy provides a cultural context for the poet's work and shows how Hughes mined African-American oral and literary traditions to create his blues-inspired poetry. Through a detailed comparison of Hughes's poems to blues texts, Tracy demonstrates how the poetics, structures, rhythms, and musical techniques of the blues are reflected in Hughes's experimental forms. The volume also includes a discography of recordings by the blues artists--Bessie Smith, Ma Rainey, Blind Lemon Jefferson, and others-who most influenced Hughes, updated in a new introduction by the author.
For more than six decades, and for thousands of students, Introduction to Logic has been the gold standard in introductory logic texts. In this fifteenth edition, Carl Cohen and Victor Rodych update Irving M. Copi’s classic text, improving on its many strengths and introducing new and helpful material that will greatly assist both students and instructors. In particular, chapters 1, 8, and 9 have been greatly enhanced without disturbing the book’s clear and gradual pedagogical approach. Specifically: Chapter 1 now uses a simpler and better definition of "deductive validity," which enhances the rest of the book (especially chapters 1 and 8-10, and their new components). Chapter 8 now has: Simpler definitions of "simple statement" and "compound statement" More and more detailed examples of the Complete Truth-Table Method. Chapter 9 now has: A detailed, step-by-step account of the Shorter Truth-Table Method (with detailed step-by-step examples for conclusions of different types) A more complete and detailed account of Indirect Proof A detailed justification for Indirect Proof treating each of the three distinct ways in which an argument can be valid A new section on Conditional Proof, which complements the 19 Rules of Inference and Indirect Proof Explications of proofs of tautologies using both Indirect Proof and Conditional Proof A new section at the end of the chapter explaining the important difference between sound and demonstrative arguments. The Appendices now include: A new appendix on making the Shorter Truth-Table Technique (STTT) more efficient by selecting the most efficient sequence of STTT steps A new appendix on Step 1 calculations for multiple-line shorter truth tables A new appendix on unforced truth-value assignments, invalid arguments, and Maxims III-V. In addition, a Companion Website will offer: for Students: A Proof Checker Complete Truth Table Exercises Shorter Truth-Table Exercises A Truth-Table Video Venn Diagram Testing of Syllogisms Hundreds of True/False and Multiple Choice Questions for Instructors: An Instructor’s Manual A Solutions Manual www.routledge.com/cw/9781138500860
The twentieth century has seen the rise of modern central banking. At its close, it is also witnessing the first steps in the decline of the role of some of the most famous of these institutions. In this volume, some of the world’s best known specialists examine the process whereby central banks emerged and asserted themselves within the economic and political spheres of their respective countries. Although the theory and the political economy that presided over their creation did not show great divergence across borders, a considerable institutional variety was nevertheless the result. Among the many factors responsible for this diversity, attention is drawn here not only to the idiosyncrasies of domestic financial systems and to the occurrence of political shocks with major monetary repercussions, such as wars, but also to the peculiarities of each economy and of the political and social climate reigning at the time when central banks were created or formalized. The twelve essays cover European, Asian and American experiences and many of them use a comparative approach.
Named a Best Book of the Year by The New Yorker and The Boston Globe An authoritative, illuminating, and deeply humane history of addiction—a phenomenon that remains baffling and deeply misunderstood despite having touched countless lives—by an addiction psychiatrist striving to understand his own family and himself “Carl Erik Fisher’s The Urge is the best-written and most incisive book I’ve read on the history of addiction. In the midst of an overdose crisis that grows worse by the hour and has vexed America for centuries, Fisher has given us the best prescription of all: understanding. He seamlessly blends a gripping historical narrative with memoir that doesn’t self-aggrandize; the result is a full-throated argument against blaming people with substance use disorder. The Urge is a propulsive tour de force that is as healing as it is enjoyable to read.” —Beth Macy, author of Dopesick Even after a decades-long opioid overdose crisis, intense controversy still rages over the fundamental nature of addiction and the best way to treat it. With uncommon empathy and erudition, Carl Erik Fisher draws on his own experience as a clinician, researcher, and alcoholic in recovery as he traces the history of a phenomenon that, centuries on, we hardly appear closer to understanding—let alone addressing effectively. As a psychiatrist-in-training fresh from medical school, Fisher was soon face-to-face with his own addiction crisis, one that nearly cost him everything. Desperate to make sense of the condition that had plagued his family for generations, he turned to the history of addiction, learning that the current quagmire is only the latest iteration of a centuries-old story: humans have struggled to define, treat, and control addictive behavior for most of recorded history, including well before the advent of modern science and medicine. A rich, sweeping account that probes not only medicine and science but also literature, religion, philosophy, and public policy, The Urge illuminates the extent to which the story of addiction has persistently reflected broader questions of what it means to be human and care for one another. Fisher introduces us to the people who have endeavored to address this complex condition through the ages: physicians and politicians, activists and artists, researchers and writers, and of course the legions of people who have struggled with their own addictions. He also examines the treatments and strategies that have produced hope and relief for many people with addiction, himself included. Only by reckoning with our history of addiction, he argues—our successes and our failures—can we light the way forward for those whose lives remain threatened by its hold. The Urge is at once an eye-opening history of ideas, a riveting personal story of addiction and recovery, and a clinician’s urgent call for a more expansive, nuanced, and compassionate view of one of society’s most intractable challenges.
