The Roots Of Walden And The Tree Of Life

Robinson tells the story of a mind at work, focusing on Thoreau's idea of "natural life" as both a subject of study and a model for personal growth and ethical purpose. "The best, most thoughtful, most carefully worked out account of Thoreau's major ideas."--Robert D. Richardson, Jr., author of "Emerson: The Mind on Fire"

At the end of the eighteenth century, scientists for the first time demonstrated what medieval and renaissance alchemists had long suspected; ice is not lifeless but vital, a crystalline revelation of vigorous powers. Studied in esoteric and exoterical representations of frozen phenomena, several Romantic figures - including Coleridge and Poe, Percy and Mary Shelley, Emerson and Thoreau - challenged traditional notions of ice as waste and instead celebrated crystals, glaciers, and the poles as special disclosures of a holistic principle of being. The Spiritual History of Ice explores this ecology of frozen shapes in fascinating detail, revealing not only a neglected current of the Romantic age but also a secret history and psychology of ice.

Reimagining Thoreau synthesizes the interests of the intellectual and psychological biographer and the literary critic in a reconsideration of Thoreau's career from his graduation from Harvard in 1837 to his death in 1862. The purposes of the book are threefold: 1) to situate Thoreau's aims and achievements as a writer within the context of his troubled relationship to m microcosm of ante-bellum Concord; 2) to reinterpret Walden as a temporally layered text in light of the successive drafts of the book and the evidence of Thoreau's journals and contemporaneous writings; and 3) toverturn traditional views of Thoreau's decline by offering a new estimate of the post-Walden writing and its place within Thoreau's development.

Since colonial times, the sense of encountering an unseen, transcendental Presence within the natural world has been a characteristic motif in American literature and culture. American writers have repeatedly perceived in nature something beyond itself-and beyond themselves. In this book, John Gatta argues that the religious import of American environmental literature has yet to be fully recognized or understood. Whatever their theology, American writers have perennially construed the nonhuman world to be a source, in Rachel Carson's words, of "something that takes us out of ourselves." Making Nature Sacred explores how the quest for "natural revelation" has been pursued through successive phases of American literary and intellectual history. And it shows how the imaginative challenge of "reading" landscapes has been influenced by biblical hermeneutics. Though focused on adaptations of Judeo-Christian religious traditions, it also samples Native American, African American, and Buddhist forms of ecospirituality. It begins with Colonial New England writers such Anne Bradstreet and Jonathan Edwards, re-examines pivotal figures such as Henry Thoreau and John Muir, and takes account of writings by Mary Austin, Rachel Carson, and many others along the way. The book concludes with an assessment of the "spiritual renaissance" underway in current environmental writing, as represented by five noteworthy poets and by authors such as Wendell Berry, Annie Dillard, Marilynne Robinson, Peter Matthiessen, and Barry Lopez. This engaging study should appeal not only to students of literature, but also to those interested in ethics and environmental studies, religious studies, and American cultural history.

The Natural Law of Cycles assembles scientific work from different disciplines to show how research on angular momentum and rotational symmetry can be used to develop a law of energy cycles as a local and global influence. Angular momentum regulates small-scale rotational cycles such as the swimming of fish in water, the running of animals on land, and the flight of birds in air. Also, it regulates large-scale rotation cycles such as global currents of wind and water.James H. Bunn introduces concepts of symmetry, balance, and angular momentum, showing how together they shape the mobile symmetries of animals. Chapter 1 studies the configurations of animals as they move in a head-first direction. Chapter 2 shows how sea animals follow currents and tides generated by the rotational cycles of the earth. In chapter 3, Bunn explores the biomechanical pace of walking as a partial cycle of rotating limbs. On a large scale, angular momentum governs balanced shifts in plate tectonics.Chapter 4 begins with an examination of rotational wind patterns in terms of the counter-balancing forces of angular momentum. The author shows how these winds augment the flights of birds during migrations. A final chapter centres on the conservation of energy as the most basic principle of science. Bunn argues that in the nineteenth century the unity of nature was seen in the emergent concept of energy, not matter, as the source of power, including the movements of animals and machines. In each chapter Bunn features environmental writers who celebrate mobile symmetries. This book will interest students, naturalists, and advocates of the environmental movement.
