"e;The fate of our times is characterized by rationalization and intellectualization and, above all, by 'the disenchantment of the world.'"e; Max Weber's statement remains a dominant interpretation of the modern condition: the increasing capabilities of knowledge and science have banished mysteries, leaving a world that can be mastered technically and intellectually. And though this idea seems empowering, many people have become disenchanted with modern disenchantment. Using intimate encounters with works of art to explore disenchantment and the possibilities of re-enchantment, Arts of Wonder addresses questions about the nature of humanity, the world, and God in the wake of Weber's diagnosis of modernity.?Jeffrey L. Kosky focuses on a handful of artists-Walter De Maria, Diller + Scofidio, James Turrell, and Andy Goldworthy-to show how they introduce spaces hospitable to mystery and wonder, redemption and revelation, and transcendence and creation. What might be thought of as religious longings, he argues, are crucial aspects of enchanting secularity when developed through encounters with these works of art. Developing a model of religion that might be significant to secular culture, Kosky shows how this model can be employed to deepen interpretation of the art we usually view as representing secular modernity. A thoughtful dialogue between philosophy and art, Arts of Wonder will catch the eye of readers of art and religion, philosophy of religion, and art criticism.

The ideas of Charles Darwin and his fellow Victorian scientists have had an abiding effect on the modern world. But at the time The Origin of Species was published in 1859, the British public looked not to practicing scientists but to a growing group of professional writers and journalists to interpret the larger meaning of scientific theories in terms they could understand and in ways they could appreciate. Victorian Popularizers of Science focuses on this important group of men and women who wrote about science for a general audience in the second half of the nineteenth century.Bernard Lightman examines more than thirty of the most prolific, influential, and interesting popularizers of the day, investigating the dramatic lecturing techniques, vivid illustrations, and accessible literary styles they used to communicate with their audience. By focusing on a forgotten coterie of science writers, their publishers, and their public, Lightman offers new insights into the role of women in scientific inquiry, the market for scientific knowledge, tensions between religion and science, and the complexities of scientific authority in nineteenth-century Britain.

During the first half of the twentieth century, representatives of the French colonial health services actively strove to expand the practice of Western medicine in the frontier colony of Cambodia. But as the French physicians ventured beyond their colonial enclaves, they found themselves negotiating with the plurality of Cambodian cultural practices relating to health and disease. These negotiations were marked by some success, a great deal of misunderstanding, and much failure.Bringing together colorful historical vignettes, social and anthropological theory, and quantitative analyses, Mixed Medicines examines these interactions between the Khmer, Cham, and Vietnamese of Cambodia and the French, documenting the differences in their understandings of medicine and revealing the unexpected transformations that occurred during this period-for both the French and the indigenous population.

In 1401, Christine de Pizan (1365-1430?), one of the most renowned and prolific woman writers of the Middle Ages, wrote a letter to the provost of Lille criticizing the highly popular and widely read Romance of the Rose for its blatant and unwarranted misogynistic depictions of women. The debate that ensued, over not only the merits of the treatise but also of the place of women in society, started Europe on the long path to gender parity. Pizan's criticism sparked a continent-wide discussion of issues that is still alive today in disputes about art and morality, especially the civic responsibility of a writer or artist for the works he or she produces.In Debate of the "e;Romance of the Rose,"e; David Hult collects, along with the debate documents themselves, letters, sermons, and excerpts from other works of Pizan, including one from City of Ladies-her major defense of women and their rights-that give context to this debate.?Here, Pizan's supporters and detractors are heard alongside her own formidable, protofeminist voice.The resulting volume affords a rare look at the way people read and thought about literature in the period immediately preceding the era of print.

These recent achievements have their origins in things women (and some male supporters) said for the first time about six hundred years ago. Theirs is the “other voice,” in contradistinction to the “first voice,” the voice of the educated men who created Western culture. Coincident with a general reshaping of European culture in the period 1300- 1700 (called the Renaissance or early modern period), questions of female equality and op-portunity were raised that still resound and are still unresolved.

There have been many Spinozas over the centuries: atheist, romantic pantheist, great thinker of the multitude, advocate of the liberated individual, and rigorous rationalist. The common thread connecting all of these clashing perspectives is Spinoza's naturalism, the idea that humanity is part of nature, not above it.?In this sophisticated new interpretation of Spinoza's iconoclastic philosophy, Hasana Sharp draws on his uncompromising naturalism to rethink human agency, ethics, and political practice. Sharp uses Spinoza to outline a practical wisdom of "e;renaturalization,"e; showing how ideas, actions, and institutions are never merely products of human intention or design, but outcomes of the complex relationships among natural forces beyond our control. This lack of a metaphysical or moral division between humanity and the rest of nature, Sharp contends, can provide the basis for an ethical and political practice free from the tendency to view ourselves as either gods or beasts.?Sharp's groundbreaking argument critically engages with important contemporary thinkers-including deep ecologists, feminists, and race and critical theorists-making Spinoza and the Politics of Renaturalization vital for a wide range of scholars.

Drawing on a broad foundation in the history of nineteenth-century French art, Richard Shiff offers an innovative interpretation of Cezanne's painting. He shows how Cezanne's style met the emerging criteria of a "e;technique of originality"e; and how it satisfied critics sympathetic to symbolism as well as to impressionism. Expanding his study of the interaction of Cezanne and his critics, Shiff considers the problem of modern art in general. He locates the core of modernism in a dialectic of making (technique) and finding (originality). Ultimately, Shiff provides not only clarifying accounts of impressionism and symbolism but of a modern classicism as well.

The writings of William Gilmore Simms (1806-1870) provide a sweeping fictional portrait of the colonial and antebellum South in all of its regional diversity. Simms's account of the region is more comprehensive than that of any other author of his time; he treats the major intellectual and social issues of the South and depicts the bonds and tensions among all of its inhabitants. By the mid-1840s Simms's novels were so well known that Edgar Allan Poe could call him "e;the best novelist which this country has, on the whole, produced."e; The thirteenth volume in the ongoing Arkansas Edition of the works of Simms, The Partisan is the first in order of publication of Simms's Revolutionary War romances. Although Simms took advantage of the novelist's prerogative to invent characters and events for his saga, he did so with a historian's eye, making extensive use of official histories; letters, diaries, and other documents; family traditions; and unpublished and published memoirs. Simms gives human interest to the novel's historical framework with two love triangles, mixing romantic conventions with gritty realism that outlines the four classes of Simms's ideal society. The Partisan is also remarkable among Simms's work for its use of symbols, indicating, perhaps, a new intention for the novel. The result is a satisfying work of literary art enlivened with adventure and humor while remaining true to the history behind it.
