His simple but profound musings—as well as Civil Disobedience, his protest against the government's interference with civil liberty—have inspired many to embrace his philosophy of individualism and love of nature.

    So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the “eel question”: Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even today, in an age of advanced science, no one has ever seen eels mating or giving birth, and we still don’t understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery.Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson writes a book about this unusual animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel’s point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea.Blending memoir and nature writing, Svensson’s journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death.

    . . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.

    A staunch atheist and rationalist, she is profoundly shaken by the implications of her life-long search. Part memoir, part philosophical and spiritual inquiry, Living with a Wild God brings an older woman's wry and erudite perspective to a young girl's uninhibited musings on the questions that, at one point or another, torment us all. Ehrenreich's most personal book ever will spark a lively and heated conversation about religion and spirituality, science and morality, and the "meaning of life." Certain to be a classic, Living with a Wild God combines intellectual rigor with a frank account of the inexplicable, in Ehrenreich's singular voice, to produce a true literary achievement.

    Her long-term research has revealed much of what we now know about these complex and intelligent animals. Here she chronicles the lives of the members of the T families led by matriarchs Teresia, Slit Ear, Torn Ear, Tania, and Tuskless. With a new afterword catching up on the families and covering current conservation issues, Moss's story will continue to fascinate animal lovers."One is soon swept away by this 'Babar' for adults. By the end, one even begins to feel an aversion for people. One wants to curse human civilization and cry out, 'Now God stand up for the elephants!'"—Christopher Lehmann-Haupt, New York Times"Moss speaks to the general reader, with charm as well as scientific authority. . . . [An] elegantly written and ingeniously structured account." —Raymond Sokolov, Wall Street Journal"Moss tells the story in a style so conversational . . . that I felt like a privileged visitor riding beside her in her rickety Land-Rover as she showed me around the park." —Sarah Blaffer Hrdy, New York Times Book Review"A prose-poem celebrating a species from which we could learn some moral as well as zoological lessons." —Chicago Tribune

    In this book the Dutchers reflect on the virtues they observed in wolf society and behavior. Each chapter exemplifies a principle, such as kindness, teamwork, playfulness, respect, curiosity, and compassion. Their heartfelt stories combine into a thought-provoking meditation on the values shared between the human and the animal world. Occasional photographs bring the wolves and their behaviors into absorbing focus.

    But as animals can only be spied on by getting quite close Heinrich adopts ravens, thereby becoming a "raven father," as well as observing them in their natural habitat, studying their daily routines, and in the process painting a vivid picture of the world as lived by the ravens. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation andanalysis, we become their intimates too.Throughout history there has existed an extraordinary relationship between humans and ravens. Ravens, like early humans, are scavengers on the kills of great carnivores. As scavengers, ravens were associated with hunters they found in the north: wolves and, later, men. The trinity of wolf, man, and raven in the hunt is an extremely ancient one. In considering the appeal of the raven, Bernd Heinrich suspects that a meeting of the minds might reside in that hunting trinity.Heinrich's passion for ravens has led him around the world in his research. Mind of the Raven takes you on an exotic journey--from New England to Germany, Montana to Baffin Island in the high Arctic--offering dazzling accounts of how science works in the field, filtered through the eyes of a passionate observer of nature.Heinrich has a true gift; through his stories, his beautiful writing, illustrations, and photography, the ravens come alive. Each new discovery and insight into their behavior is thrilling to read. just as the title promises, the reader is given a rare glimpse into the mind of these wonderful creatures.Following the dictum of Leonardo da Vinci--"It is not enough to believe what you see. YOU Must also understand what you see"--Bernd Heinrich enables us to see the natural world through the eyes of a scientist. At once lyrical and scientific, Mind of the Raven is bound to be a modern classic.

    He has been both a socialist opposed to the war in Vietnam and a supporter of the U.S. war against Islamic extremism in Iraq. He has been both a foreign correspondent in some of the world's most dangerous places and a legendary bon vivant with an unquenchable thirst for alcohol and literature. He is a fervent atheist, raised as a Christian, by a mother whose Jewish heritage was not revealed to him until her suicide. In other words, Christopher Hitchens contains multitudes. He sees all sides of an argument. And he believes the personal is political. This is the story of his life, a life lived large.

    Magpies, he soon discovers, are as clever and mischievous as monkeys. They are also notorious thieves, and this one quickly steals his heart. By the time the creature develops shiny black feathers that inspire the name Benzene, Charlie and the bird have forged an unbreakable bond. While caring for Benzene, Charlie learns his biological father, an eccentric British poet named Heathcote Williams who vanished when Charlie was six months old, is ill. As he grapples with Heathcote’s abandonment, Charlie comes across one of his poems, in which Heathcote describes how an impish young jackdaw fell from its nest and captured his affection. Over time, Benzene helps Charlie unravel his fears about repeating the past—and embrace the role of father himself. A bird falls, a father dies, a child is born. Featherhood is the unforgettable story of a love affair between a man and a bird. It is also a beautiful and affecting memoir about childhood and parenthood, captivity and freedom, grief and love.

    Bekoff skillfully blends extraordinary stories of animal joy, empathy, grief, embarrassment, anger, and love with the latest scientific research confirming the existence of emotions that common sense and experience have long implied. Filled with Bekoff’s light humor and touching stories, The Emotional Lives of Animals is a clarion call for reassessing both how we view animals and how we treat them.

    Fossey's extraordinary efforts to ensure the future of the rain forest and its remaining mountain gorillas are captured in her own words and in candid photographs of this fascinating endangered species. As only she could, Fossey combined her personal adventure story with groundbreaking scientific reporting in an unforgettable portrait of one of our closest primate relatives. Although Fossey's work ended tragically in her murder, Gorillas in the Mist remains an invaluable testament to one of the longest-running field studies of primates and reveals her undying passion for her subject.

    Robert Macfarlane travels Britain's ancient paths and discovers the secrets of our beautiful, underappreciated landscape.Following the tracks, holloways, drove-roads and sea paths that form part of a vast ancient network of routes criss-crossing the British Isles and beyond, Robert Macfarlane discovers a lost world - a landscape of the feet and the mind, of pilgrimage and ritual, of stories and ghosts; above all of the places and journeys which inspire and inhabit our imaginations.

    Here is the Naked Ape at his most primal in love, at work, at war. Meet man as he really is: relative to the apes, stripped of his veneer as we see him courting, making love, sleeping, socializing, grooming, playing. The Naked Ape takes its place alongside Darwin’s Origin of the Species, presenting man not as a fallen angel, but as a risen ape, remarkable in his resilience, energy and imagination, yet an animal nonetheless, in danger of forgetting his origins. With its penetrating insights on man's beginnings, sex life, habits and our astonishing bonds to the animal kingdom, The Naked Ape is a landmark, at once provocative, compelling and timeless.

    The knowledge and fear of the existence of these ferocious man-eaters is forever in the back of our minds, looming in our worst nightmares. Millions of humans have suffered attacks by predators on land and at sea. Yet animals have always shared the landscape with humans. Since the dawn of time our ecosystems have been linked and humans have co-existed with flesh-eating beasts as members of the same food chain. Now, of course, as humans spread and despoil the planet, these fearsome predators may only survive on the other side of glass barriers and chain-link fences. Their gradual disappearance is changing the nature of our own existence. We no longer occupy an intermediate position on the food chain; instead we survey it invulnerably from above - so far above that we are in danger of forgetting that we even belong to an ecosystem.David Quammen's enthralling new book covers the four corners of the globe as he explores the fate of lions in India's Gir forest, saltwater crocodiles in Northern Australia, brown bears in the mountains of Romania, and Siberian tigers. Tracking these great and terrible beasts through the toughest terrain in the world, Quammen is equally intrigued by the traditional relationship between the great predators and the people who live among them, and weaves into his story the fears and myths that have haunted humankind for 3000 years.

    To a smaller yet no less passionate audience, Fowles is also known for having written The Tree, one of his few works of nonfiction. First published a generation ago, it is a provocative meditation on the connection between the natural world and human creativity, and a powerful argument against taming the wild. In it, Fowles recounts his own childhood in England and describes how he rebelled against his Edwardian father’s obsession with the “quantifiable yield” of well-pruned fruit trees and came to prize instead the messy, purposeless beauty of nature left to its wildest. The Tree is an inspiring, even life-changing book, like Lewis Hyde’s The Gift, one that reaffirms our connection to nature and reminds us of the pleasure of getting lost, the merits of having no plan, and the wisdom of following one’s nose wherever it may lead—in life as much as in art.
