Admittedly, computers now play chess at the grandmaster level, but do they understand the game as we do? Can a computer eventually do everything a human mind can do? In this absorbing and frequently contentious book, Roger Penrose--eminent physicist and winner, with Stephen Hawking, of the prestigious Wolf prize--puts forward his view that there are some facets of human thinking that can never be emulated by a machine. Penrose examines what physics and mathematics can tell us about how the mind works, what they can't, and what we need to know to understand the physical processes of consciousness. He is among a growing number of physicists who think Einstein wasn't being stubborn when he said his little finger told him that quantum mechanics is incomplete, and he concludes that laws even deeper than quantum mechanics are essential for the operation of a mind. To support this contention, Penrose takes the reader on a dazzling tour that covers such topics as complex numbers, Turing machines, complexity theory, quantum mechanics, formal systems, Godel undecidability, phase spaces, Hilbert spaces, black holes, white holes, Hawking radiation, entropy, quasicrystals, the structure of the brain, and scores of other subjects. The Emperor's New Mind will appeal to anyone with a serious interest in modern physics and its relation to philosophical issues, as well as to physicists, mathematicians, philosophers and those on either side of the AI debate.

    That collaboration would mark the dawn of modern science . . . and end in murder.Johannes Kepler changed forever our understanding of the universe with his three laws of planetary motion. He demolished the ancient model of planets moving in circular orbits and laid the foundation for the universal law of gravitation, setting physics on the course of revelation it follows to this day. Kepler was one of the greatest astronomers of all time. Yet if it hadn't been for the now lesser-known Tycho Brahe, the man for whom Kepler apprenticed, Kepler would be a mere footnote in today's science books. Brahe was the Imperial Mathematician at the court of the Holy Roman Emperor in Prague and the most famous astronomer of his era. He was one of the first great systematic empirical scientists and one of the earliest founders of the modern scientific method. His forty years of planetary observations—an unparalleled treasure of empirical data—contained the key to Kepler's historic breakthrough. But those observations would become available to Kepler only after Brahe's death. This groundbreaking history portrays the turbulent collaboration between these two astronomers at the turn of the seventeenth century and their shattering discoveries that would mark the transition from medieval to modern science. But that is only half the story. Based on recent forensic evidence (analyzed here for the first time) and original research into medieval and Renaissance alchemy—all buttressed by in-depth interviews with leading historians, scientists, and medical specialists—the authors have put together shocking and compelling evidence that Tycho Brahe did not die of natural causes, as has been believed for four hundred years. He was systematically poisoned—most likely by his assistant, Johannes Kepler. An epic tale of murder and scientific discovery, Heavenly Intrigue reveals the dark side of one of history’s most brilliant minds and tells the story of court politics, personal intrigue, and superstition that surrounded the protean invention of two great astronomers and their quest to find truth and beauty in the heavens above.

    Tender and joyous, it is a celebration of art's power to transform the darkest of human experience and give voice to the grandest of human hopes.

    This engaging book--part scientific overview, part memoir, part futurist speculation--describes Koch's search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest--his instinctual (if "romantic") belief that life is meaningful.Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness (once considered a "fringy" subject) as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action.Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work--to uncover the roots of consciousness.

    In The Ego Tunnel, philosopher Thomas Metzinger claims otherwise: No such thing as a self exists. The conscious self is the content of a model created by our brain—an internal image, but one we cannot experience as an image. Everything we experience is “a virtual self in a virtual reality.”But if the self is not “real,” why and how did it evolve? How does the brain construct it? Do we still have souls, free will, personal autonomy, or moral accountability? In a time when the science of cognition is becoming as controversial as evolution, The Ego Tunnel provides a stunningly original take on the mystery of the mind.

    Millions of patients are now routinely being given prescriptions for a wide range of drugs including Ritalin, Prosac, Zoloft and related drugs which can be harmful to the brain. A previous generation of patients would have had a course of psychotherapy without brain–damaging chemicals. Glasser explains the wide implications of this radical change in treatment and what can be done to counter it.

    When Sigmund Freud awakened modern interest in the dream a century ago, his theory of interpretation undermined the potential insights dreams had to offer. For Freud, dreams were little more than fragmented puzzle parts made up of events from our waking lives. Most of us today still live under Freud's far-reaching influence. When we wake up after experiencing a powerful series of images, we too readily explain them away or simply ignore them all together. Whatever emotion or insight the dream evokes slowly fades. But what if Freud was wrong? Unless we challenge his deeply-ingrained assumptions, we will forever lose the gift of our dreams.International bestselling author Rodger Kamenetz believes it is not too late to reclaim the lost power of our nightly visions. Kamenetz's exploration of the world of dreams reopens all the questions scientists and psychologists claimed to have settled long ago. The culmination of decades of research, The History of Last Night's Dream is a riveting intellectual and cultural investigation of dreams and what they have to teach us. We discover how the age-old struggle between what we dream and how we interpret our dreams has shaped Western culture from biblical times to today. Kamenetz introduces us to an eighty-seven-year-old female kabbalist in Jerusalem, a suave Tibetan Buddhist dream teacher in Copenhagen, and a crusty intuitive postman-turned-dream master in northern Vermont. He fearlessly delves into this mysterious inner realm and shows us that dreams are not only intensely meaningful but that they hold essential truths about who we are. In the end, each of us has the choice to embark on this illuminating path to the soul. But one thing is certain: our dreams will never be the same again.

    A language that can only be heard when one truly listens. It’s the language of The Spirit Whisperer.         In John Holland’s past books, he explained how he came to terms with, and learned to accept and embrace, his spiritual gifts as a psychic medium; and how “readers” could develop their own intuitive psychic abilities.     In this book, John picks up the fascinating story of his personal journey of growth and development as one of the most respected practicing mediums today. This work chronicles his career to date and includes some enlightening and heartfelt real-life case studies. He candidly discusses readings with clients, including those who’ve had their own After Death Communications (ADCs)—from the outrageous to the profound. John also explains the signs and symbols that our loved ones continually try to send us. One of his most popular sayings is: “Those on the Other Side want to talk to you—as much as you want to talk to them!”John divulges for the first time some of the extraordinary paranormal occurrences he’s witnessed throughout his career, and provides a rare glimpse behind the scenes of what it’s like to be a “Psychic Time Machine” for several television shows. He’ll also help parents who have a psychic child themselves. The Spirit Whisperer is a book you’ll want to read over and over, as many of the stories will touch your heart as well as your soul!

    To truly flourish, the human spirit needs to be present in its surroundings and attuned to the Now. It needs to act on what it knows is possible and to experience how the smallest actions can have massive consequences. This is the reality of the Prophet’s Way, a path--both literal and figurative--that the author walked with his spiritual mentor Herr Müller that skirts the edge of the precipice, where one can experience a truly spontaneous life under seemingly overwhelming and impossible circumstances.In The Prophet’s Way, Thom Hartmann shares his intense spiritual journey, a story that melds recent discoveries in science with ancient truths. Through insightful and engaging vignettes Hartmann teaches that accepting the challenge to have faith means living on the edge--remaining in the moment--because it is here where the material and spiritual worlds meet. He offers readers a unique view into his experiences of expanded consciousness, providing a powerful example of how we can re-create our future by reconnecting to the sacred heartbeat of the world.

    Before this explosive growth into the modern age took place, an all-but-forgotten genius strove for forty years to win acceptance for the atomic theory of matter and an altogether new way of doing physics. Ludwig Boltz-mann battled with philosophers, the scientific establishment, and his own potent demons. His victory led the way to the greatest scientific achievements of the twentieth century. Now acclaimed science writer David Lindley portrays the dramatic story of Boltzmann and his embrace of the atom, while providing a window on the civilized world that gave birth to our scientific era. Boltzmann emerges as an endearingly quixotic character, passionately inspired by Beethoven, who muddled through the practical matters of life in a European gilded age. Boltzmann's story reaches from fin de siecle Vienna, across Germany and Britain, to America. As the Habsburg Empire was crumbling, Germany's intellectual might was growing; Edinburgh in Scotland was one of the most intellectually fertile places on earth; and, in America, brilliant independent minds were beginning to draw on the best ideas of the bureaucratized old world.Boltzmann's nemesis in the field of theoretical physics at home in Austria was Ernst Mach, noted today in the term Mach I, the speed of sound. Mach believed physics should address only that which could be directly observed. How could we know that frisky atoms jiggling about corresponded to heat if we couldn't see them? Why should we bother with theories that only told us what would probably happen, rather than making an absolute prediction? Mach and Boltzmann both believed in the power of science, but their approaches to physics could not have been more opposed. Boltzmann sought to explain the real world, and cast aside any philosophical criteria. Mach, along with many nineteenth-century scientists, wanted to construct an empirical edifice of absolute truths that obeyed strict philosophical rules. Boltzmann did not get on well with authority in any form, and he did his best work at arm's length from it. When at the end of his career he engaged with the philosophical authorities in the Viennese academy, the results were personally disastrous and tragic. Yet Boltzmann's enduring legacy lives on in the new physics and technology of our wired world.Lindley's elegant telling of this tale combines the detailed breadth of the best history, the beauty of theoretical physics, and the psychological insight belonging to the finest of novels.

    In the realm of ethics, this corresponded to the philosophical tenet that to do what is ethical is to do what corresponds to an abstract set of rules. By contrast to this computationalism, the author places central emphasis on what he terms enaction--cognition as the ability to negotiate embodied, everyday living in a world that is inseparable from our sensory-motor capacities.Apart from his researches in cognitive science, the bodies of thought that enable Varela to make this link are phenomenology and two representatives of what he calls the wisdom traditions: Confucian ethics and Buddhist epistemology. From the Confucian tradition, he draws upon the Mencius to propose an ethics of praxis, one in which ethical action is conceived as a project of being rather than as a system of judgment, less a matter of rules that are universally applicable than a goal of expertise, sagehood.The Buddhist contribution to his project encompasses the embodiment of the void and the pragmatics of a virtual self. How does a belief system that does not posit a unitary self or subject conceive the living of an I? In summation, the author proposes an ethics founded on savoir faire that is a practice of transformation based on a constant recognition of the virtual nature of ourselves in the actual operations of our mental lives.

    But most residents of Denmark and Sweden, he found, don't worship any god at all, don't pray, and don't give much credence to religious dogma of any kind. Instead of being bastions of sin and corruption, however, as the Christian Right has suggested a godless society would be, these countries are filled with residents who score at the very top of the "happiness index" and enjoy their healthy societies, which boast some of the lowest rates of violent crime in the world (along with some of the lowest levels of corruption), excellent educational systems, strong economies, well-supported arts, free health care, egalitarian social policies, outstanding bike paths, and great beer.Zuckerman formally interviewed nearly 150 Danes and Swedes of all ages and educational backgrounds over the course of fourteen months. He was particularly interested in the worldviews of people who live their lives without religious orientation. How do they think about and cope with death? Are they worried about an afterlife? What he found is that nearly all of his interviewees live their lives without much fear of the Grim Reaper or worries about the hereafter. This led him to wonder how and why it is that certain societies are non-religious in a world that seems to be marked by increasing religiosity. Drawing on prominent sociological theories and his own extensive research, Zuckerman ventures some interesting answers.This fascinating approach directly counters the claims of outspoken, conservative American Christians who argue that a society without God would be hell on earth. It is crucial, Zuckerman believes, for Americans to know that "society without God is not only possible, but it can be quite civil and pleasant."
