This cycle is at the root of all addictions, addictions to drugs, sex, love, cigarettes, soap operas, wealth, and wisdom itself. But why should this be so? Why are we desperate for what we don't have, or can't have, often at great cost to what we do have, thereby risking our peace and contentment, our safety, and even our lives?"The answer, says Dr. Marc Lewis, lies in the structure and function of the human brain. Marc Lewis is a distinguished neuroscientist. And, for many years, he was a drug addict himself, dependent on a series of dangerous substances, from LSD to heroin. His narrative moves back and forth between the often dark, compellingly recounted story of his relationship with drugs and a revelatory analysis of what was going on in his brain. He shows how drugs speak to the brain - which is designed to seek rewards and soothe pain - in its own language. He shows in detail the neural mechanics of a variety of powerful drugs and of the onset of addiction, itself a distortion of normal perception.Dr. Lewis freed himself from addiction and ended up studying it. At the age of 30 he traded in his pharmaceutical supplies for the life of a graduate student, eventually becoming a professor of developmental psychology, and then of neuroscience - his field for the last 12 years. This is the story of his journey, seen from the inside out.

    As a student and young researcher in the 1980s, Gelernter hoped to build a program with a dial marked "focus." At maximum "focus," the program would "think" rationally, formally, reasonably. As the dial was turned down and "focus" diminished, its "mind" would start to wander, and as you dialed even lower, this artificial mind would start to free-associate, eventually ignoring the user completely as it cruised off into the mental adventures we know as sleep.While the program was a only a partial success, it laid the foundation for The Tides of Mind, a groundbreaking new exploration of the human psyche that shows us how the very purpose of the mind changes throughout the day. Indeed, as Gelernter explains, when we are at our most alert, when reasoning and creating new memories is our main mental business, the mind is a computer-like machine that keeps emotion on a short leash and attention on our surroundings. As we gradually tire, however, and descend the "mental spectrum," reasoning comes unglued. Memory ranges more freely, the mind wanders, and daydreams grow more insistent. Self-awareness fades, reflection blinks out, and at last we are completely immersed in our own minds.With far-reaching implications, Gelernter’s landmark "Spectrum of Consciousness" finally helps decode some of the most mysterious wonders of the human mind, such as the numinous light of early childhood, why dreams are so often predictive, and why sadism and masochism underpin some of our greatest artistic achievements. It’s a theory that also challenges the very notion of the mind as a machine—and not through empirical studies or "hard science" but by listening to our great poets and novelists, who have proven themselves as humanity's most trusted guides to the subjective mind and inner self.In the great introspective tradition of Wilhelm Wundt and René Descartes, David Gelernter promises to not only revolutionize our understanding of what it means to be human but also to help answer many of our most fundamental questions about the origins of creativity, thought, and consciousness.

    Or the blissful abandon of a golden retriever racing with glee across a lawn. This is the joy of play. By definition, play is purposeless and all-consuming. And, most important, it’s fun. As we become adults, taking time to play feels like a guilty pleasure—a distraction from “real” work and life. But as Dr. Stuart Brown illustrates, play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition. In fact, our ability to play throughout life is the single most important factor in determining our success and happiness. Dr. Brown has spent his career studying animal behavior and conducting more than six thousand “play histories” of humans from all walks of life—from serial murderers to Nobel Prize winners. Backed by the latest research, Play explains why play is essential to our social skills, adaptability, intelligence, creativity, ability to problem solve, and more. Play is hardwired into our brains—it is the mechanism by which we become resilient, smart, and adaptable people. Beyond play’s role in our personal fulfillment, its benefits have profound implications for child development and the way we parent, education and social policy, business innovation, productivity, and even the future of our society. From new research suggesting the direct role of three-dimensional-object play in shaping our brains to animal studies showing the startling effects of the lack of play, Brown provides a sweeping look at the latest breakthroughs in our understanding of the importance of this behavior. A fascinating blend of cutting-edge neuroscience, biology, psychology, social science, and inspiring human stories of the transformative power of play, this book proves why play just might be the most important work we can ever do.

    The book takes the nonspecialist reader on a guided tour through the exciting new discoveries, pointing out along the way how old psychodynamic concepts are being forged into a new scientific framework for understanding subjective experience - in health and disease.

    The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. If machine brains surpassed human brains in general intelligence, then this new superintelligence could become extremely powerful--possibly beyond our control. As the fate of the gorillas now depends more on humans than on the species itself, so would the fate of humankind depend on the actions of the machine superintelligence.But we have one advantage: we get to make the first move. Will it be possible to construct a seed Artificial Intelligence, to engineer initial conditions so as to make an intelligence explosion survivable? How could one achieve a controlled detonation?

    Sleep patterns may be the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. Living at odds with our internal timepieces, Till Roenneberg shows, can make us chronically sleep deprived and more likely to smoke, gain weight, feel depressed, fall ill, and fail geometry. By understanding and respecting our internal time, we can live better.Internal Time combines storytelling with accessible science tutorials to explain how our internal clocks work—for example, why morning classes are so unpopular and why “lazy” adolescents are wise to avoid them. We learn why the constant twilight of our largely indoor lives makes us dependent on alarm clocks and tired, and why social demands and work schedules lead to a social jet lag that compromises our daily functioning.Many of the factors that make us early or late “chronotypes” are beyond our control, but that doesn’t make us powerless. Roenneberg recommends that the best way to sync our internal time with our external environment and feel better is to get more sunlight. Such simple steps as cycling to work and eating breakfast outside may be the tickets to a good night’s sleep, better overall health, and less grouchiness in the morning.[Description taken from publisher's web site.]

    He shows that from our 20s into our 40s, happiness follows a U-shaped trajectory, a “happiness curve,” declining from the optimism of youth into what’s often a long, low slump in middle age, before starting to rise again in our 50s.This isn’t a midlife crisis, though. Rauch reveals that this slump is instead a natural stage of life—and an essential one. By shifting priorities away from competition and toward compassion, it equips you with new tools for wisdom and gratitude to win the third period of life. And Rauch can testify to this personally because it was his own slump, despite acclaim as a journalist and commentator that compelled him to investigate the happiness curve. His own story and the stories of many others from all walks of life—from a steelworker and a limo driver to a telecoms executive and a philanthropist—show how the ordeal of midlife malaise reboots our values and even our brains for a rebirth of gratitude. Full of insights and data and featuring many ways to endure the slump and avoid its perils and traps, The Happiness Curve doesn’t just show you the dark forest of midlife, it helps you find a path through the trees. It also demonstrates how we can—and why we must—do more to help each other through the woods. Midlife is a journey we mustn’t walk alone.

    Seligman draws on more than twenty years of clinical research to demonstrate how optimism enchances the quality of life, and how anyone can learn to practice it. Offering many simple techniques, Dr. Seligman explains how to break an “I—give-up” habit, develop a more constructive explanatory style for interpreting your behavior, and experience the benefits of a more positive interior dialogue. These skills can help break up depression, boost your immune system, better develop your potential, and make you happier.. With generous additional advice on how to encourage optimistic behavior at school, at work and in children, Learned Optimism is both profound and practical–and valuable for every phase of life.

    The outcome was unexpected—when Henry awoke, he could no longer form new memories, and for the rest of his life would be trapped in the moment. But Henry’s tragedy would prove a gift to humanity. As renowned neuroscientist Suzanne Corkin explains in Permanent Present Tense, she and her colleagues brought to light the sharp contrast between Henry’s crippling memory impairment and his preserved intellect. This new insight that the capacity for remembering is housed in a specific brain area revolutionized the science of memory. The case of Henry—known only by his initials H. M. until his death in 2008—stands as one of the most consequential and widely referenced in the spiraling field of neuroscience. Corkin and her collaborators worked closely with Henry for nearly fifty years, and in Permanent Present Tense she tells the incredible story of the life and legacy of this intelligent, quiet, and remarkably good-humored man. Henry never remembered Corkin from one meeting to the next and had only a dim conception of the importance of the work they were doing together, yet he was consistently happy to see her and always willing to participate in her research. His case afforded untold advances in the study of memory, including the discovery that even profound amnesia spares some kinds of learning, and that different memory processes are localized to separate circuits in the human brain. Henry taught us that learning can occur without conscious awareness, that short-term and long-term memory are distinct capacities, and that the effects of aging-related disease are detectable in an already damaged brain.Undergirded by rich details about the functions of the human brain, Permanent Present Tense pulls back the curtain on the man whose misfortune propelled a half-century of exciting research. With great clarity, sensitivity, and grace, Corkin brings readers to the cutting edge of neuroscience in this deeply felt elegy for her patient and friend.

    It argues that evolution designed us both to teach and learn, and that the drive to learn is our most important instinct. It also reveals as fascinating insights about our adult capacities and how even young children -- as well as adults -- use some of the same methods that allow scientists to learn so much about the world. Filled with surprise at every turn, this vivid, lucid, and often funny book gives us a new view of the inner life of children and the mysteries of the mind.

    But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we can find our common ground. A grand synthesis of neuroscience, psychology, and philosophy, Moral Tribes reveals the underlying causes of modern conflict and lights the way forward. Greene compares the human brain to a dual-mode camera, with point-and-shoot automatic settings (“portrait,” “landscape”) as well as a manual mode. Our point-and-shoot settings are our emotions—efficient, automated programs honed by evolution, culture, and personal experience. The brain’s manual mode is its capacity for deliberate reasoning, which makes our thinking flexible. Point-and-shoot emotions make us social animals, turning Me into Us. But they also make us tribal animals, turning Us against Them. Our tribal emotions make us fight—sometimes with bombs, sometimes with words—often with life-and-death stakes. An award-winning teacher and scientist, Greene directs Harvard University’s Moral Cognition Lab, which uses cutting-edge neuroscience and cognitive techniques to understand how people really make moral decisions. Combining insights from the lab with lessons from decades of social science and centuries of philosophy, the great question of Moral Tribes is this: How can we get along with Them when what they want feels so wrong to Us? Ultimately, Greene offers a set of maxims for navigating the modern moral terrain, a practical road map for solving problems and living better lives. Moral Tribes shows us when to trust our instincts, when to reason, and how the right kind of reasoning can move us forward. A major achievement from a rising star in a new scientific field, Moral Tribes will refashion your deepest beliefs about how moral thinking works and how it can work better.

    This work represents the views of a mathematician on the analogies between computing machines and the living human brain.

    In an Internet society, according to Richard Susskind and Daniel Susskind, we will neither need nor want doctors, teachers, accountants, architects, the clergy, consultants, lawyers, and many others, to work as they did in the 20th century.The Future of the Professions explains how 'increasingly capable systems' -- from telepresence to artificial intelligence -- will bring fundamental change in the way that the 'practical expertise' of specialists is made available in society.The authors challenge the 'grand bargain' -- the arrangement that grants various monopolies to today's professionals. They argue that our current professions are antiquated, opaque and no longer affordable, and that the expertise of their best is enjoyed only by a few. In their place, they propose six new models for producing and distributing expertise in society.The book raises important practical and moral questions. In an era when machines can out-perform human beings at most tasks, what are the prospects for employment, who should own and control online expertise, and what tasks should be reserved exclusively for people?Based on the authors' in-depth research of more than ten professions, and illustrated by numerous examples from each, this is the first book to assess and question the relevance of the professions in the 21st century.
