The basic assumption is that vision depends on the eye which is connected to the brain. The author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision -- and what this book is about.

    Over the past decade, Silicon Valley executives like Eric Schmidt and Elon Musk, Special Operators like the Navy SEALs and the Green Berets, and maverick scientists like Sasha Shulgin and Amy Cuddy have turned everything we thought we knew about high performance upside down. Instead of grit, better habits, or 10,000 hours, these trailblazers have found a surprising short cut. They're harnessing rare and controversial states of consciousness to solve critical challenges and outperform the competition.New York Times bestselling author Steven Kotler and high performance expert Jamie Wheal spent four years investigating the leading edges of this revolution—from the home of SEAL Team Six to the Googleplex, the Burning Man festival, Richard Branson’s Necker Island, Red Bull’s training center, Nike’s innovation team, and the United Nations’ Headquarters. And what they learned was stunning: In their own ways, with differing languages, techniques, and applications, every one of these groups has been quietly seeking the same thing: the boost in information and inspiration that altered states provide.Today, this revolution is spreading to the mainstream, fueling a trillion dollar underground economy and forcing us to rethink how we can all lead richer, more productive, more satisfying lives. Driven by four accelerating forces—psychology, neurobiology, technology and pharmacology—we are gaining access to and insights about some of the most contested and misunderstood terrain in history. Stealing Fire is a provocative examination of what’s actually possible; a guidebook for anyone who wants to radically upgrade their life.

    . . A tour de force of a book that begs to be seen as well as to be read."--The Washington Post Book WorldWorld renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals.Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

    In Emotions Revealed, he assembles his research and theories to provide a comprehensive look at the evolutionary roots of human emotions, including anger, sadness, fear, disgust, and happiness. Drawing on decades of fieldwork, Ekman shows that emotions are deeply embedded in the human species. In the process, he answers such questions as: What triggers emotions and can we stop them? How does our body signal to others whether we are slightly sad or anguished, peeved or enraged? Can we learn to distinguish between a polite smile and the genuine thing? Can we ever truly control our emotions? Unique exercises and photographs help readers identify emotions in themselves and others. Emotions Revealed is a practical, mind-opening, and potentially life-changing exploration of science and self. c

    Three eminent psychiatrists tackle the difficult task of reconciling what artists and thinkers have known for thousands of years about the human heart with what has only recently been learned about the primitive functions of the human brain.A General Theory of Love demonstrates that our nervous systems are not self-contained: from earliest childhood, our brains actually link with those of the people close to us, in a silent rhythm that alters the very structure of our brains, establishes life-long emotional patterns, and makes us, in large part, who we are. Explaining how relationships function, how parents shape their child’s developing self, how psychotherapy really works, and how our society dangerously flouts essential emotional laws, this is a work of rare passion and eloquence that will forever change the way you think about human intimacy.

    If...we could ask and it could reply, it would give up to us the most intimate secrets of life. -from Chapter II Anticipating not only modern scientific theories of psychology but also those of cosmology, this astonishing book sets out a impressive goal for itself: to reconcile human biology with a theory of consciousness. First published in France in 1907, and translated into English in 1911, this work of wonder was esteemed at the time in scientific circles and in the popular culture alike for its profound explorations of perception and memory and its surprising conclusions about the nature and value of art. Contending that intuition is deeper than intellect and that the real consequence of evolution is a mental freedom to grow, to change, to seek and create novelty, Bergson reinvigorated the theory of evolution by refusing to see it as merely mechanistic. His expansion on Darwin remains one of the most original and important philosophical arguments for a scientific inquiry still under fire today. French philosopher HENRI BERGSON (1859-1941) was born in Paris. Among his works are Matter and Memory (1896), An Introduction to Metaphysics (1903), and The Two Sources of Morality and Religion (1932). He was awarded the Nobel Prize for Literature in 1927.

    That's taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren't more women physicists or more stay-at-home dads.In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of "human brain organization theory," Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out the limits of their own studies, other researchers and journalists can easily ignore them because brain organization theory just sounds so right. But if a series of methodological weaknesses, questionable assumptions, inconsistent definitions, and enormous gaps between ambiguous findings and grand conclusions have accumulated through the years, then science isn't scientific at all.Elegantly written, this book argues passionately that the analysis of gender differences deserves far more rigorous, biologically sophisticated science. "The evidence for hormonal sex differentiation of the human brain better resembles a hodge-podge pile than a solid structure... Once we have cleared the rubble, we can begin to build newer, more scientific stories about human development."

    . . when it comes to the legacy of this country's war on drugs, we should all share his outrage." --The New York Times Book Review From one of the world's foremost experts on the subject, a powerful argument that the greatest damage from drugs flows from their being illegal, and a hopeful reckoning with the possibility of their use as part of a responsible and happy lifeDr. Carl L. Hart, Ziff Professor at Columbia University and former chair of the Department of Psychology, is one of the world's preeminent experts on the effects of so-called recreational drugs on the human mind and body. Dr. Hart is open about the fact that he uses drugs himself, in a happy balance with the rest of his full and productive life as a colleague, husband, father, and friend. In Drug Use for Grown-Ups, he draws on decades of research and his own personal experience to argue definitively that the criminalization and demonization of drug use--not drugs themselves--have been a tremendous scourge on America, not least in reinforcing this country's enduring structural racism.Dr. Hart did not always have this view. He came of age in one of Miami's most troubled neighborhoods at a time when many ills were being laid at the door of crack cocaine. His initial work as a researcher was aimed at proving that drug use caused bad outcomes. But one problem kept cropping up: the evidence from his research did not support his hypothesis. From inside the massively well-funded research arm of the American war on drugs, he saw how the facts did not support the ideology. The truth was dismissed and distorted in order to keep fear and outrage stoked, the funds rolling in, and Black and brown bodies behind bars.Drug Use for Grown-Ups will be controversial, to be sure: the propaganda war, Dr. Hart argues, has been tremendously effective. Imagine if the only subject of any discussion about driving automobiles was fatal car crashes. Drug Use for Grown-Ups offers a radically different vision: when used responsibly, drugs can enrich and enhance our lives. We have a long way to go, but the vital conversation this book will generate is an extraordinarily important step.

    Their struggle to survive on the open grasslands required a shift from individualism to a new form of collectivism, which forever altered the way our mind works. It changed the way we fight and our proclivity to make peace, it changed the way we lead and the way we follow, it made us innovative but not inventive, it created a new kind of social intelligence, and it led to new sources of life satisfaction.In The Social Leap, William von Hippel lays out this revolutionary hypothesis, tracing human development through three critical evolutionary inflection points to explain how events in our distant past shape our lives today. From the mundane, such as why we exaggerate, to the surprising, such as why we believe our own lies and why fame and fortune are as likely to bring misery as happiness, the implications are far reaching and extraordinary.Blending anthropology, biology, history, and psychology with evolutionary science, The Social Leap is a fresh and provocative look at our species that provides new clues about who we are, what makes us happy, and how to use this knowledge to improve our lives.

    Why does music evoke such powerful moods? The answers are at last be- coming clear, thanks to revolutionary neuroscience and the emerging field of evolutionary psychology. Both a cutting-edge study and a tribute to the beauty of music itself, This Is Your Brain on Music unravels a host of mysteries that affect everything from pop culture to our understanding of human nature, including: • Are our musical preferences shaped in utero? • Is there a cutoff point for acquiring new tastes in music? • What do PET scans and MRIs reveal about the brain’s response to music? • Is musical pleasure different from other kinds of pleasure?This Is Your Brain on Music explores cultures in which singing is considered an essential human function, patients who have a rare disorder that prevents them from making sense of music, and scientists studying why two people may not have the same definition of pitch. At every turn, this provocative work unlocks deep secrets about how nature and nurture forge a uniquely human obsession.

    The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by issues of aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science, creating a new understanding of energy use and metabolism: West found that despite the riotous diversity in the sizes of mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. This speaks to everything from how long we can expect to live to how many hours of sleep we need. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism's body. West's work has been game-changing for biologists, but then he made the even bolder move of exploring his work's applicability to cities. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. For every doubling in a city's size, the city needs 15% less road, electrical wire, and gas stations to support the same population. More amazingly, for every doubling in size, cities produce 15% more patents and more wealth, as well as 15% more crime and disease. This broad pattern lays the groundwork for a new science of cities. Recently, West has applied his revolutionary work on cities and biological life to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune, however diverse and unrelated they are to each other.From the Hardcover edition.

    Through a series of entertaining, bite-sized chapters that combine anthropological insight with cutting-edge science, we gain fresh perspectives into our first hominin ancestors and ways to challenge perceptions about the traditional progression of evolution. With Lee as our guide, we discover that we indeed have always been a species of continuous change.

    Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, Honeybee Democracy brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees.In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together--as a swirling cloud of bees--to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution.An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.

    In pursuit of these things, it is undeterred by emotion, fear, or morality. Dopamine is the source of our every urge, that little bit of biology that makes an ambitious business professional sacrifice everything in pursuit of success, or that drives a satisfied spouse to risk it all for the thrill of someone new. Simply put, it is why we seek and succeed; it is why we discover and prosper. Yet, at the same time, it’s why we gamble and squander. From dopamine’s point of view, it’s not the having that matters. It’s getting something—anything—that’s new. From this understanding—the difference between possessing something versus anticipating it—we can understand in a revolutionary new way why we behave as we do in love, business, addiction, politics, religion – and we can even predict those behaviors in ourselves and others. In The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and will Determine the Fate of the Human Race, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and why the brains of liberals and conservatives really are different.

    In addition, it should have repercussions in a variety of disciplines, ranging from anthropology and psychology to epistemology and the philosophy of science. . . . Lakoff asks: What do categories of language and thought reveal about the human mind? Offering both general theory and minute details, Lakoff shows that categories reveal a great deal."—David E.
