It has been reprinted in Ideas and Opinions, Crown Publishers, Inc. 1954, pp 36 - 40. It also appears in Einstein's book The World as I See It, Philosophical Library, New York, 1949, pp. 24 - 28.Everything that the human race has done and thought is concerned with the satisfaction of deeply felt needs and the assuagement of pain. One has to keep this constantly in mind if one wishes to understand spiritual movements and their development. Feeling and longing are the motive force behind all human endeavor and human creation, in however exalted a guise the latter may present themselves to us. Now what are the feelings and needs that have led men to religious thought and belief in the widest sense of the words? A little consideration will suffice to show us that the most varying emotions preside over the birth of religious thought and experience. With primitive man it is above all fear that evokes religious notions - fear of hunger, wild beasts, sickness, death. Since at this stage of existence understanding of causal connections is usually poorly developed, the human mind creates illusory beings more or less analogous to itself on whose wills and actions these fearful happenings depend. Thus one tries to secure the favor of these beings by carrying out actions and offering sacrifices which, according to the tradition handed down from generation to generation, propitiate them or make them well disposed toward a mortal. In this sense I am speaking of a religion of fear. This, though not created, is in an important degree stabilized by the formation of a special priestly caste which sets itself up as a mediator between the people and the beings they fear, and erects a hegemony on this basis. In many cases a leader or ruler or a privileged class whose position rests on other factors combines priestly functions with its secular authority in order to make the latter more secure; or the political rulers and the priestly caste make common cause in their own interests.

    Despite decades of research and millions of dollars invested in uncovering the causes and developing treatments for this devastating illness, progress has been slow, with each new "blockbuster" drug proving to be as big a disappointment as the ones that went before it. Today, an Alzheimer's diagnosis is a death sentence.However, there may be ways to prevent, delay, and possibly even reverse the course of this crippling neurodegenerative disease. In The Alzheimer's Antidote, Certified Nutrition Specialist Amy Berger presents a multi-pronged nutrition and lifestyle intervention to combat Alzheimer's disease at its roots. Berger's research shows that Alzheimer's results from a fuel shortage in the brain: As neurons become unable to harness energy from glucose, they atrophy and die, leading to classic symptoms like memory loss and behavioral changes.This is a revolutionary approach--one that has been discussed in the scientific literature for years but has only recently been given credence in clinical settings, thanks to extremely promising studies wherein Alzheimer's patients have experienced complete reversals of the condition. Medical and scientific journals are full of research showing alternate ways to fuel the starving brain, but no one has been bringing this essential information to the people who need it most--until now.In a culture obsessed with miracle medications, the pharmaceutical route for tackling Alzheimer's has been a massive failure. Pills and potions don't address underlying causes, and regarding Alzheimer's, they typically fail to improve even the symptoms. As a metabolic problem, the only effective way to treat Alzheimer's may be a multifaceted approach that fundamentally reprograms energy generation in the brain. The good news is, the secret is as simple as switching to a low-carb, high-fat diet.The Alzheimer's Antidote shows us that cognitive decline is not inevitable, but if it does occur, we don't have to sit idly by and wait helplessly while it progresses and worsens. Amy Berger empowers loved ones and caregivers of Alzheimer's sufferers, and offers hope and light against this otherwise unnavigable labyrinth of darkness.

    Elsewhere, a team of scientists transverses the tundra, sleeping in tents, surviving on frozen chocolate, and measuring the snow every ten kilometers in a quest to understand the effects of albedo, the snow's reflective ability to cool the earth beneath it.Climate change isn't an abstraction in the far North. It is a reality that has already dramatically altered daily life, especially that of the native peoples who still live largely off the land and sea. Because nature shows her footprints so plainly here, the region is also a lure for scientists intent on comprehending the complexities of climate change. In this gripping account, Charles Wohlforth follows the two groups as they navigate a radically shifting landscape. The scientists attempt to decipher its smallest elements and to derive from them a set of abstract laws and models. The natives draw on uncannily accurate traditional knowledge, borne of long experience living close to the land. Even as they see the same things-a Native elder watches weather coming through too fast to predict; a climatologist notes an increased frequency of cyclonic systems-the two cultures struggle to reconcile their vastly different ways of comprehending the environment.With grace, clarity, and a sense of adventure, Wohlforth--a lifelong Alaskan--illuminates both ways of seeing a world in flux, and in the process, helps us to navigate a way forward as climate change reaches us all.

    Now one of the most dynamic writers and one of the most respected scientists in the field of climate change offer the first concise guide to both the problems and the solutions. Guiding us past a blizzard of information and misinformation, Gabrielle Walker and Sir David King explain the science of warming, the most cutting-edge technological solutions from small to large, and the national and international politics that will affect our efforts. While there have been many other books about the problem of global warming, none has addressed what we can and should do about it so clearly and persuasively, with no spin, no agenda, and no exaggeration. Neither Walker nor King is an activist or politician, and theirs is not a generic green call to arms. Instead they propose specific ideas to fix a very specific problem. Most important, they offer hope: This is a serious issue, perhaps the most serious that humanity has ever faced. But we can still do something about it. And they’ll show us how.

    First Life travels the world, from Canada to Australia, Morocco to Scotland, to unearth the secrets hidden in prehistoric fossils and meet the palaeontologists who have harnessed new techniques to enhance greatly our understanding of the origins of life.With an introduction by David Attenborough, and insights captured during the making of the television series, this book is a journey of discovery, showing us what these early animals would have looked like and how they would have lived, bringing them to life with the help of modern computer technology. First Life shows us how evolutionary features of the first creatures have been passed down to modern animals, including humans, giving us amazing insight into the remarkable evolutionary journey that has brought us here today.

    Indeed, if God knows everything, why do we need to learn through pain and suffering? If God is omnipotent, why are we needed to do good? If the universe is fundamentally good, why are wars, crime, and injustice all around us? In modern society, orthodox science takes the rational high-ground and tackles these contradictions by denying the very need for, and the existence of, meaning. Indeed, many of us implicitly accept the notion that rationality somehow contradicts spirituality. That is a modern human tragedy, not only for its insidiousness, but for the fact that it is simply not true. In this book, the author constructs a coherent and logical argument for the meaning of existence, informed by science itself. A framework is laid out wherein all aspects of human existence have a logical, coherent reason and role, including the ones often perceived as negative. The powerful logic of this framework inescapably leads to insightful and inspiring guidelines for living a purposeful and meaningful life.

    But in the past fifteen years, a revolutionary new standard of measurement—sabermetrics—has been embraced by front offices in Major League Baseball and among fantasy baseball enthusiasts. But while sabermetrics is recognized as being smarter and more accurate, traditionalists, including journalists, fans, and managers, stubbornly believe that the "old" way—a combination of outdated numbers and "gut" instinct—is still the best way. Baseball, they argue, should be run by people, not by numbers.?In this informative and provocative book, teh renowned ESPN analyst and senior baseball writer demolishes a century’s worth of accepted wisdom, making the definitive case against the long-established view. Armed with concrete examples from different eras of baseball history, logic, a little math, and lively commentary, he shows how the allegiance to these numbers—dating back to the beginning of the professional game—is firmly rooted not in accuracy or success, but in baseball’s irrational adherence to tradition.While Law gores sacred cows, from clutch performers to RBIs to the infamous save rule, he also demystifies sabermetrics, explaining what these "new" numbers really are and why they’re vital. He also considers the game’s future, examining how teams are using Data—from PhDs to sophisticated statistical databases—to build future rosters; changes that will transform baseball and all of professional sports.

    The first is the astonishing achievement of the Human Genome Project, which, it was anticipated, would identify the genetic basis of those characteristics that distinguish humans from their primate cousins. The second is the phenomenal advance in brain imaging that now permits neuroscientists to observe the brain 'in action' and thus account for the remarkable properties of the human mind.But that is not how it has turned out. It is simply not possible to get from the monotonous sequence of genes along the Double Helix to the near infinite diversity of the living world, nor to translate the electrical firing of the brain into the creativity of the human mind. This is not a matter of not knowing all the facts. Rather, science has inadvertently discovered that its theories are insufficient to conjure the wonder of the human experience from the bare bones of our genes and brains.We stand on the brink of a tectonic shift in our understanding of ourselves that will witness the rediscovery of the central premise of Western philosophy that there is 'more than we can know'. Lucid, compelling and utterly engaging, ‘Why Us?’ offers a convincing and provocative vision of the new science of being human.

    But now, with revolutionary medical advances, death has become just another serious complication. As a young medical student, Dr. David Casarett was inspired by the story of a two-year-old girl named Michelle Funk. Michelle fell into a creek and was underwater for over an hour. When she was found she wasn’t breathing, and her pupils were fixed and dilated. That drowning should have been fatal. But after three hours of persistent work, a team of doctors and nurses was able to bring her back. It was a miracle. If Michelle could come back after three hours of being dead, what about twelve hours? Or twenty-four? What would it take to revive someone who had been frozen for one thousand years? And what does blurring the line between “life” and “death” mean for society? In Shocked, Casarett chronicles his exploration of the cutting edge of resuscitation and reveals just how far science has come. He begins in the eighteenth century, when early attempts at resuscitation involved public displays of barrel rolling, horseback riding (sort of), and blowing smoke up the patient’s various orifices. He then takes us inside a sophisticated cryonics facility in the Arizona desert, a darkroom full of hibernating lemurs in North Carolina, and a laboratory that puts mice into a state of suspended animation. The result is a spectacular tour of the bizarre world of doctors, engineers, animal biologists, and cryogenics enthusiasts trying to bring the recently dead back to life. Fascinating, thought-provoking, and (believe it or not) funny, Shocked is perfect for those looking for a prequel—and a sequel—to Mary Roach’s Stiff, or for anyone who likes to ponder the ultimate questions of life and death.

    Gleick's story begins at the turn of the twentieth century with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation, The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. Gleick tracks the evolution of time travel as an idea in the culture from Marcel Proust to Doctor Who, from Woody Allen to Jorge Luis Borges. He explores the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.
