Imbued with character and independence, strength and articulateness, humor and conviction, abundant biblical knowledge and intense compassion, Katharina Schutz Zell (1498-1562) was an outspoken religious reformer in sixteenth-century Germany who campaigned for the right of clergy to marry and the responsibility of lay people-women as well as men-to proclaim the Gospel. As one of the first and most daring models of the pastor's wife in the Protestant Reformation, Schutz Zell demonstrated that she could be an equal partner in marriage; she was for many years a respected, if unofficial, mother of the established church of Strasbourg in an age when ecclesiastical leadership was dominated by men.Though a commoner, Schtz Zell participated actively in public life and wrote prolifically, including letters of consolation, devotional writings, biblical meditations, catechetical instructions, a sermon, and lengthy polemical exchanges with male theologians. The complete translations of her extant publications, except for her longest, are collected here in Church Mother, offering modern readers a rare opportunity to understand the important work of women in the formation of the early Protestant church.

So certain is this that we may boldly state that it is absurd for human beings even to attempt it, or to hope that perhaps some day another Newton might arise who would explain to us, in terms of natural laws unordered by intention, how even a mere blade of grass is produced．Kant, Critique of Judgment (1790)

Recent battles in Washington over how to fix America's fiscal failures strengthened the widespread impression that economic issues sharply divide average citizens. Indeed, many commentators split Americans into two opposing groups: uncompromising supporters of unfettered free markets and advocates for government solutions to economic problems. But such dichotomies, Benjamin Page and Lawrence Jacobs contend, ring false. In Class Warthey present compelling evidence that most Americans favor free enterprise and practical government programs to distribute wealth more equitably.At every income level and in both major political parties, majorities embrace conservative egalitarianism-a philosophy that prizes individualism and self-reliance as well as public intervention to help Americans pursue these ideals on a level playing field. Drawing on hundreds of opinion studies spanning more than seventy years, including a new comprehensive survey, Page and Jacobs reveal that this worldview translates to broad support for policies aimed at narrowing the gap between rich and poor and creating genuine opportunity for all. They find, for example, that across economic, geographical, and ideological lines, most Americans support higher minimum wages, improved public education, wider access to universal health insurance coverage, and the use of tax dollars to fund these programs.In this surprising and heartening assessment, Page and Jacobs provide our new administration with a popular mandate to combat the economic inequity that plagues our nation.

A timely and multifaceted portrait of the lawyers who serve the diverse constituencies of the conservative movement, Lawyers of the Right explains what unites and divides lawyers for the three major groups-social conservatives, libertarians, and business advocates-that have coalesced in recent decades behind the Republican Party. Drawing on in-depth interviews with more than seventy lawyers who represent conservative and libertarian nonprofit organizations, Ann Southworth explores their values and identities and traces the implications of their shared interest in promoting political strategies that give lawyers leading roles. She goes on to illuminate the function of mediator organizations-such as the Heritage Foundation and the Federalist Society for Law and Public Policy-that have succeeded in promoting cooperation among different factions of conservative lawyers. Such cooperation, she finds, has aided efforts to drive law and the legal profession politically rightward and to give lawyers greater prominence in the conservative movement. Southworth concludes, though, that tensions between the conservative law movement's elite and populist elements may ultimately lead to its undoing.

Seven decades after his death, German Jewish writer, philosopher, and literary critic Walter Benjamin (1892-1940) continues to fascinate and influence. Here Uwe Steiner offers a comprehensive and sophisticated introduction to the oeuvre of this intriguing theorist.Acknowledged only by a small circle of intellectuals during his lifetime, Benjamin is now a major figure whose work is essential to an understanding of modernity. Steiner traces the development of Benjamin's thought chronologically through his writings on philosophy, literature, history, politics, the media, art, photography, cinema, technology, and theology. Walter Benjamin reveals the essential coherence of its subject's thinking while also analyzing the controversial or puzzling facets of Benjamin's work. That coherence, Steiner contends, can best be appreciated by placing Benjamin in his proper context as a member of the German philosophical tradition and a participant in contemporary intellectual debates.As Benjamin's writing attracts more and more readers in the English-speaking world, Walter Benjamin will be a valuable guide to this fascinating body of work.

Over the past half-century, bookselling, like many retail industries, has evolved from an arena dominated by independent bookstores to one in which chain stores have significant market share. And as in other areas of retail, this transformation has often been a less-than-smooth process. This has been especially pronounced in bookselling, argues Laura J. Miller, because more than most other consumer goods, books are the focus of passionate debate. What drives that debateAnd why do so many people believe that bookselling should be immune to questions of profit?In Reluctant Capitalists, Miller looks at a century of book retailing, demonstrating that the independent/chain dynamic is not entirely new. It began one hundred years ago when department stores began selling books, continued through the 1960s with the emergence of national chain stores, and exploded with the formation of "e;superstores"e; in the 1990s. The advent of the Internet has further spurred tremendous changes in how booksellers approach their business. All of these changes have met resistance from book professionals and readers who believe that the book business should somehow be "e;above"e; market forces and instead embrace more noble priorities.Miller uses interviews with bookstore customers and members of the book industry to explain why books evoke such distinct and heated reactions. She reveals why customers have such fierce loyalty to certain bookstores and why they identify so strongly with different types of books. In the process, she also teases out the meanings of retailing and consumption in American culture at large, underscoring her point that any type of consumer behavior is inevitably political, with consequences for communities as well as commercial institutions.

The Arkansas Gazette was born in a log cabin November 20, 1819, on a bank of the Arkansas River. A local establishment donated a barrel of whiskey to celebrate the event. The first issue carried a complaint from a citizen that the town had too many lawyers. When the paper died 167 years later, the problem was not lawyers but corporate executives who had found themselves, to their confusion, in charge of the oldest newspaper west of the Mississippi and not knowing what to do with it.

William Gilmore Simms's (1806-1870) body of work, a sweeping fictional portrait of the colonial and antebellum South in all its regional diversity, with its literary and intellectual issues, is probably more comprehensive than any other nineteenth-century southern author. Simms's career began with a short novel, Martin Faber, published in 1833. This Gothic tale is reminiscent of James Hogg's Confessions of a Sinner and was written four years before Edgar Allan Poe's "e;William Wilson."e; Narrated in the first person, it is considered a pioneering examination of criminal psychology. Martin seduces then murders Emily so that he might marry another woman, Constance. Martin confesses to his friend and is killed after attempting to stab Constance when she visits him in jail. The book was immediately successful and was well received by the northern media, thus starting Simms's successful career as a writer, one that would rank him as the only major southern literary figure besides Poe before the Civil War. As with other volumes in the Arkansas Edition of Simms's work, this volume includes a critical introduction by the editor and a Simms chronology, as well as appendices dealing with textual matters. This edition also includes Simms's 1829 story, "e;Confessions of a Murderer,"e; which was the germ for his first book of fiction.

Worthy of the Cause for Which They Fight chronicles the experiences of a well-educated and articulate Confederate officer from Arkansas who witnessed the full evolution of the Civil War in the Trans-Mississippi Department and western theater. Daniel Harris Reynolds, a community leader with a thriving law practice in Chicot County, entered service in 1861 as a captain in command of Company A of the First Arkansas Mounted Rifles. Reynolds saw action at Wilson's Creek and Pea Ridge before the regiment was dismounted and transferred to the Army of Tennessee, the primary Confederate force in the western theater. As Reynolds fought through the battles of Chickamauga, Atlanta, Nashville, and Bentonville, he consistently kept a diary in which he described the harsh realities of battle, the shifting fortunes of war, and the personal and political conflicts that characterized and sometimes divided the soldiers. The result is a significant testimonial offering valuable insights into the nature of command from the company to brigade levels, expressed by a committed Southerner coming to grips with the realities of defeat and the ultimate demoralization of surrender.

A Documentary History of Arkansas provides a comprehensive look at Arkansas history from the state's earliest events to the present. Here are newspaper articles, government bulletins, legislative acts, broadsides, letters, and speeches that, taken collectively, give a firsthand glimpse at how the twenty-fifth state's history was made. Enhanced by additional documents and brought up to date since its original publication in 1984, this new edition is the standard source for essential primary documents illustrating the state's political, social, economic, educational, and environmental history.

Not Without Honor threads together the stories of three American POWs-Carano; his buddy Bill Blackmon, who was also at Stalag 17 b; and John C. Bitzer, who survived the brutal "e;Death March"e; from northern Germany to liberation in April 1945. At times the journal reads like a thriller as he records air battles and escape attempts. Yet in their most gripping accounts, these POWs ruminate on psychological survival. The sense of community they formed was instrumental to their endurance. This compelling book allows the reader to journey with these young men as they bore firsthand witness to the best and worst of human nature.

With the arrival of the transcontinental railroad in the 1880s came the emergence of a modern and profoundly multicultural New Mexico. Native Americans, working-class Mexicans, elite Hispanos, and black and white newcomers all commingled and interacted in the territory in ways that had not been previously possible. But what did it mean to be white in this multiethnic milieuAnd how did ideas of sexuality and racial supremacy shape ideas of citizenry and determine who would govern the region?Coyote Nation considers these questions as it explores how New Mexicans evaluated and categorized racial identities through bodily practices. Where ethnic groups were numerous and-in the wake of miscegenation-often difficult to discern, the ways one dressed, bathed, spoke, gestured, or even stood were largely instrumental in conveying one's race. Even such practices as cutting one's hair, shopping, drinking alcohol, or embalming a deceased loved one could inextricably link a person to a very specific racial identity.A fascinating history of an extraordinarily plural and polyglot region, Coyote Nation will be of value to historians of race and ethnicity in American culture.
