The Cave and the Light is a magisterial account of how the two greatest thinkers of the ancient world, Plato and Aristotle, laid the foundations of Western culture—and how their rivalry shaped the essential features of our culture down to the present day.   Plato came from a wealthy, connected Athenian family and lived a comfortable upper-class lifestyle until he met an odd little man named Socrates, who showed him a new world of ideas and ideals. Socrates taught Plato that a man must use reason to attain wisdom, and that the life of a lover of wisdom, a philosopher, was the pinnacle of achievement. Plato dedicated himself to living that ideal and went on to create a school, his famed Academy, to teach others the path to enlightenment through contemplation.   However, the same Academy that spread Plato’s teachings also fostered his greatest rival. Born to a family of Greek physicians, Aristotle had learned early on the value of observation and hands-on experience. Rather than rely on pure contemplation, he insisted that the truest path to knowledge is through empirical discovery and exploration of the world around us. Aristotle, Plato’s most brilliant pupil, thus settled on a philosophy very different from his instructor’s and launched a rivalry with profound effects on Western culture.   The two men disagreed on the fundamental purpose of the philosophy. For Plato, the image of the cave summed up man’s destined path, emerging from the darkness of material existence to the light of a higher and more spiritual truth. Aristotle thought otherwise. Instead of rising above mundane reality, he insisted, the philosopher’s job is to explain how the real world works, and how we can find our place in it. Aristotle set up a school in Athens to rival Plato’s Academy: the Lyceum. The competition that ensued between the two schools, and between Plato and Aristotle, set the world on an intellectual adventure that lasted through the Middle Ages and Renaissance and that still continues today.   From Martin Luther (who named Aristotle the third great enemy of true religion, after the devil and the Pope) to Karl Marx (whose utopian views rival Plato’s), heroes and villains of history have been inspired and incensed by these two master philosophers—but never outside their influence.   Accessible, riveting, and eloquently written, The Cave and the Light provides a stunning new perspective on the Western world, certain to open eyes and stir debate.Praise for The Cave and the Light   “A sweeping intellectual history viewed through two ancient Greek lenses . . . breezy and enthusiastic but resting on a sturdy rock of research.”—Kirkus Reviews   “Examining mathematics, politics, theology, and architecture, the book demonstrates the continuing relevance of the ancient world.”—Publishers Weekly  “A fabulous way to understand over two millennia of history, all in one book.”—Library Journal  “Entertaining and often illuminating.”—The Wall Street JournalFrom the Hardcover edition.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Far from being an attack on science and technics, The Pentagon of Power seeks to establish a more organic social order based on technological resources. Index; photographs.

    An engaging and extremely readable book of breathtaking scope, its inspired synthesis of ecology, anthropology, and political theory traces our conflicting legacies of hierarchy and freedom, from the first emergence of human culture to today's globalized capitalism, constantly pointing the way to a sane, sustainable ecological future. On a college syllabus or in an activist's backpack, this book is indispensable reading for anyone who's tired of living in a world where everything is an exploitable resource.

    Shiva shows that a world beyond dependence on fossil fuels and globalization is both possible and necessary.Condemning industrial agriculture as a recipe for ecological and economic disaster, Shiva’s champion is the small, independent farm: their greater productivity, their greater potential for social justice as they put more resources into the hands of the poor, and the biodiversity that is inherent to the traditional farming practiced in small-scale agriculture. What we need most in a time of changing climates and millions hungry, she argues, is sustainable, biologically diverse farms that are more resistant to disease, drought, and flood. In her trademark style, she draws solutions to our world’s most pressing problems on the head of a pin: “The solution to climate change,” she observes, “and the solution to poverty are the same.”Using Shiva’s organization Navdanya—praised by Barbara Kingsolver as “a small, green Eden framed against the startling blue backdrop of the Himalayas”—as a model, Soil Not Oil lays out principles for feeding the planet that are socially just and environmentally sound. Shiva then expands her analysis to broader issues of globalization and climate change, arguing that a healthy environment and a just world go hand in hand. Unwavering and truly visionary, Soil Not Oil proposes a solution based on self-organization, sustainability, and community rather than corporate power and profits.A world-renowned environmental leader and thinker, Vandana Shiva is the author of many books, including Earth Democracy, Water Wars, and Staying Alive. She is the editor of Manifestos on the Future of Food and Seed.

    What is the meaning of life? What was Hitler's religion? What's the deal with the Flying Spaghetti Monster? And what was Mother Teresa's dark secret? This book is highly recommended for everyone curious about America's most misunderstood minority, as well as for those who wish to better understand their atheist friends, neighbors or coworkers.

    The book documents the adverse environmental effects caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.The book appeared in September 1962 and the outcry that followed its publication forced the banning of DDT and spurred revolutionary changes in the laws affecting our air, land, and water. Carson’s book was instrumental in launching the environmental movement.

    Carnism causes extensive animal suffering and global injustice, and it drives us to act against our own interests and the interests of others without fully realizing what we are doing. Becoming aware of what carnism is and how it functions is vital to personal empowerment and social transformation, as it enables us to make our food choices more freely—because without awareness, there is no free choice.

    Now Terry Tempest Williams, the author of the environmental classic Refuge and the beloved memoir When Women Were Birds, returns with The Hour of Land, a literary celebration of our national parks, an exploration of what they mean to us and what we mean to them.From the Grand Tetons in Wyoming to Acadia in Maine to Big Bend in Texas and more, Williams creates a series of lyrical portraits that illuminate the unique grandeur of each place while delving into what it means to shape a landscape with its own evolutionary history into something of our own making. Part memoir, part natural history, and part social critique, The Hour of Land is a meditation and a manifesto on why wild lands matter to the soul of America.

    How we address it in the next thirty years will determine the kind of world we will live in and will bequeath to our children and to theirs.In The Future We Choose, Christiana Figueres and Tom Rivett-Carnac--who led negotiations for the United Nations during the historic Paris Agreement of 2015--have written a cautionary but optimistic book about the world's changing climate and the fate of humanity.The authors outline two possible scenarios for our planet. In one, they describe what life on Earth will be like by 2050 if we fail to meet the Paris climate targets. In the other, they lay out what it will be like to live in a carbon neutral, regenerative world. They argue for confronting the climate crisis head-on, with determination and optimism. The Future We Choose presents our options and tells us what governments, corporations, and each of us can and must do to fend off disaster.

    Original, well researched, and well documented by distinguished sources, The Field is a book of hope and inspiration for today's world.

    Humans have "subdued 75 per cent of the land surface, concocted a wizardry of industrial and medical marvels, strung lights all across the darkness." We now collect the DNA of vanishing species in a "frozen ark," equip orangutans with iPads, create wearable technologies and synthetic species that might one day outsmart us. With her distinctive gift for making scientific discovery intelligible to the layperson, Ackerman takes us on an exciting journey to understand this bewildering new reality, introducing us to many of the people and ideas now creating--perhaps saving--the future.The Human Ageis a surprising, optimistic engagement with the dramatic transformations that have shaped, and continue to alter, our world, our relationship with nature and our prospects for the future.

    Greer fans will recognize many of the book's passages from previous essays, but will be delighted to see them fleshed out here with additional examples and analysis.The Long Descent is one of the most highly anticipated peak oil books of the year, and it lives up to every ounce of hype. Greer is a captivating, brilliantly inventive writer with a deep knowledge of history, an impressive amount of mechanical savvy, a flair for storytelling and a gift for drawing art analogies. His new book presents an astonishing view of our society's past, present and future trajectory--one that is unmatched in its breadth and depth. Reviewed by Frank KaminskiWired.com—  The Long Descent is a welcome antidote to the armageddonism that often accompanies peak oil discussions. "The decline of a civilization is rarely anything like so sudden for those who live through it" writes Greer, encouragingly; it's "a much slower and more complex transformation than the sudden catastrophes imagined by many soical critics today."The changes that will follow the decline of world petroleum production are likely to be sweeping and global, Greer concludes, but from the perspective of those who live through them these changes are much more likely to take gradual and local forms. Reviewed by Bruce SterlingAmericans are expressing deep concern about US dependence on petroleum, rising energy prices, and the threat of climate change. Unlike the energy crisis of the 1970s, however, there is a lurking fear that now the times are different and the crisis may not easily be resolved.The Long Descent examines the basis of such fear through three core themes:• Industrial society is following the same well-worn path that has led other civilizations into decline, a path involving a much slower and more complex transformation than the sudden catastrophes imagined by so many social critics today.• The roots of the crisis lie in the cultural stories that shape the way we understand the world. Since problems cannot be solved with the same thinking that created them, these ways of thinking need to be replaced with others better suited to the needs of our time.• It is too late for massive programs for top-down change; the change must come from individuals.Hope exists in actions that range from taking up a handicraft or adopting an “obsolete” technology, through planting an organic vegetable garden, taking charge of your own health care or spirituality, and building community.Focusing eloquently on constructive adaptation to massive change, this book will have wide appeal.John Michael Greer is a certified Master Conserver, organic gardener, and scholar of ecological history. The current Grand Archdruid of the Ancient Order of Druids in America (AODA), his widely-cited blog, The Archdruid Report (thearchdruidreport.blogspot.com) deals with peak oil, among other issues. He lives in Ashland, Oregon.

    As sociologist and network science pioneer Duncan Watts explains in this provocative book, the explanations that we give for the outcomes that we observe in life—explanation that seem obvious once we know the answer—are less useful than they seem.Drawing on the latest scientific research, along with a wealth of historical and contemporary examples, Watts shows how common sense reasoning and history conspire to mislead us into believing that we understand more about the world of human behavior than we do; and in turn, why attempts to predict, manage, or manipulate social and economic systems so often go awry.It seems obvious, for example, that people respond to incentives; yet policy makers and managers alike frequently fail to anticipate how people will respond to the incentives they create. Social trends often seem to have been driven by certain influential people; yet marketers have been unable to identify these “influencers” in advance. And although successful products or companies always seem in retrospect to have succeeded because of their unique qualities, predicting the qualities of the next hit product or hot company is notoriously difficult even for experienced professionals.Only by understanding how and when common sense fails, Watts argues, can we improve how we plan for the future, as well as understand the present—an argument that has important implications in politics, business, and marketing, as well as in science and everyday life.

    In recent years, newspaper headlines have screamed, “Scarce water and the death of California farms,” “The Dust Bowl returns,” “A ‘megadrought’ will grip U.S. in the coming decades.” Yet similar stories have been appearing for decades and the taps continue to flow. John Fleck argues that the talk of impending doom is not only untrue, but dangerous. When people get scared, they fight for the last drop of water; but when they actually have less, they use less. Having covered environmental issues in the West for a quarter century, Fleck would be the last writer to discount the serious problems posed by a dwindling Colorado River. But in that time, Fleck has also seen people in the Colorado River Basin come together, conserve, and share the water that is available. Western communities, whether farmers and city-dwellers or US environmentalists and Mexican water managers, have a promising record of cooperation, a record often obscured by the crisis narrative. In this fresh take on western water, Fleck brings to light the true history of collaboration and examines the bonds currently being forged to solve the Basin’s most dire threats. Rather than perpetuate the myth “Whiskey's for drinkin', water's for fightin' over," Fleck urges readers to embrace a new, more optimistic narrative—a future where the Colorado continues to flow.
