Birds were never far from Thoreau’s mind. They wing their way through his writing just as they did through his cabin on Walden Pond, summoned or dismissed at whim by his whistles. Emblematic of life, death, and nature’s endless capacity for renewal, birds offer passage into the loftiest currents of Thoreau’s thought. What Branka Arsić finds there is a theory of vitalism that Thoreau developed in response to his brother’s death. Through grieving, Thoreau came to see life as a generative force into which everything dissolves. Death is not an annulment of life but the means of its transformation and reemergence.

Bird Relics traces Thoreau’s evolving thoughts through his investigation of Greek philosophy and the influence of a group of Harvard vitalists who resisted the ideas of the naturalist Louis Agassiz. It takes into account materials often overlooked by critics: his Indian Notebooks and unpublished bird notebooks; his calendars that rewrite how we tell time; his charts of falling leaves, through which he develops a complex theory of decay; and his obsession with vegetal pathology, which inspires a novel understanding of the relationship between disease and health.

Arsić’s radical reinterpretation of Thoreau’s life philosophy gives new meaning to some of his more idiosyncratic habits, such as writing obituaries for people he did not know and frequenting estate sales, and raises important questions about the ethics of Thoreau’s practice of appropriating the losses of others as if they were his own.

With the environmental crisis comes a crisis of the imagination, a need to find new ways to understand nature and humanity's relation to it. This is the challenge Lawrence Buell takes up in The Environmental Imagination, the most ambitious study to date of how literature represents the natural environment. With Thoreau's Walden as a touchstone, Buell gives us a far-reaching account of environmental perception, the place of nature in the history of western thought, and the consequences for literary scholarship of attempting to imagine a more "ecocentric" way of being. In doing so, he provides a major new understanding of Thoreau's achievement and, at the same time, a profound rethinking of our literary and cultural reflections on nature.

The green tradition in American writing commands Buell's special attention, particularly environmental nonfiction from colonial times to the present. In works by writers from Crevecoeur to Wendell Berry, John Muir to Aldo Leopold, Rachel Carson to Leslie Silko, Mary Austin to Edward Abbey, he examines enduring environmental themes such as the dream of relinquishment, the personification of the nonhuman, an attentiveness to environmental cycles, a devotion to place, and a prophetic awareness of possible ecocatastrophe. At the center of this study we find an image of Walden as a quest for greater environmental awareness, an impetus and guide for Buell as he develops a new vision of environmental writing and seeks a new way of conceiving the relation between human imagination and environmental actuality in the age of industrialization. Intricate and challenging in its arguments, yet engagingly and elegantly written, The Environmental Imagination is a major work of scholarship, one that establishes a new basis for reading American nature writing.

In No Man's Garden, ecologist Daniel Botkin takes a fresh look at the life and writings of Henry David Thoreau to discover a model for reconciling the conflict between nature and civilization that lies at the heart of our environmental problems. He offers an insightful reinterpretation of Thoreau, drawing a surprising picture of the “hermit of Walden” as a man who loved wildness, but who found it in the woods and swamps on the outskirts of town as easily as in the remote forests of Maine, and who firmly believed in the value and importance of human beings and civilization.Botkin integrates into the familiar image of Thoreau, the solitary seeker, other, equally important aspects of his personality and career -- as a first-rate ecologist whose close, long-term observation of his surroundings shows the value of using a scientific approach, as an engineer who was comfortable working out technical problems in his father's pencil factory, and as someone who was deeply concerned about the spiritual importance of nature to people.This new view of one of the founding fathers of American environmental thought lays the groundwork for an innovative approach to solving environmental problems. Botkin argues that the topics typically thought of as “environmental,” and the issues and concerns of “environmentalism,” are in fact rooted in some of humanity's deepest concerns -- our fundamental physical and spiritual connection with nature, and the mutually beneficial ways that society and nature can persist together. He makes the case that by understanding the true scientific, philosophical, and spiritual bases of environmental positions we will be able to develop a means of preserving the health of our biosphere that simultaneously allows for the further growth and development of civilization.No Man's Garden presents a vital challenge to the assumptions and conventional wisdom of environmentalism, and will be must reading for anyone interested in developing a deeper understanding of interactions between humans and nature.

John Hildebidle reintroduces us to Thoreau as natural history writer, bringing fresh insight to Walden, Cape Cod, and the later nature pieces--both published and unpublished--and the tradition of nature writing as well.

Hildebidle examines Thoreau's attitude toward history and science, demonstrating that he manages to use "secondhand" material while insisting that only firsthand experience has any value. Although sharing the naturalist's eye and methods, Thoreau never rests in the role of observer and collector. Hildebidle sees Thoreau as representative of a long-standing American tendency simultaneously to reject and to use the past, and shows how, as naturalist, he brought together science and literary aims. This gracefully written analysis of Thoreau's thinking and style will well serve all readers of Thoreau and those interested in natural history as a genre.
