A thought-provoking argument that consciousness—more widespread than previously assumed—is the feeling of being alive, not a type of computation or a clever hack In The Feeling of Life Itself, Christof Koch offers a straightforward definition of consciousness as any subjective experience, from the most mundane to the most exalted—the feeling of being alive. Psychologists study which cognitive operations underpin a given conscious perception. Neuroscientists track the neural correlates of consciousness in the brain, the organ of the mind. But why the brain and not, say, the liver? How can the brain—three pounds of highly excitable matter, a piece of furniture in the universe, subject to the same laws of physics as any other piece—give rise to subjective experience? Koch argues that what is needed to answer these questions is a quantitative theory that starts with experience and proceeds to the brain. In The Feeling of Life Itself, Koch outlines such a theory, based on integrated information. Koch describes how the theory explains many facts about the neurology of consciousness and how it has been used to build a clinically useful consciousness meter. The theory predicts that many, and perhaps all, animals experience the sights and sounds of life; consciousness is much more widespread than conventionally assumed. Contrary to received wisdom, however, Koch argues that programmable computers will not have consciousness. Even a perfect software model of the brain is not conscious. Its simulation is fake consciousness. Consciousness is not a special type of computation—it is not a clever hack. Consciousness is about being.

From one of the world’s leading neuroscientists: a succinct, illuminating, wholly engaging investigation of how biology, neuroscience, psychology, and artificial intelligence have given us the tools to unlock the mysteries of human consciousness “One thrilling insight after another ... Damasio has succeeded brilliantly in narrowing the gap between body and mind.” —The New York Times Book Review In recent decades, many philosophers and cognitive scientists have declared the problem of consciousness unsolvable, but Antonio Damasio is convinced that recent findings across multiple scientific disciplines have given us a way to understand consciousness and its significance for human life. In the forty-eight brief chapters of Feeling & Knowing, and in writing that remains faithful to our intuitive sense of what feeling and experiencing are about, Damasio helps us understand why being conscious is not the same as sensing, why nervous systems are essential for the development of feelings, and why feeling opens the way to consciousness writ large. He combines the latest discoveries in various sciences with philosophy and discusses his original research, which has transformed our understanding of the brain and human behavior. Here is an indispensable guide to understand­ing how we experience the world within and around us and find our place in the universe.

A fascinating exploration of the human brain that combines “the leading edge of consciousness science with surprisingly personal and philosophical reflection . . . shedding light on how scientists really think”—this is “science writing at its best” (Times Higher Education). In which a scientist searches for an empirical explanation for phenomenal experience, spurred by his instinctual belief that life is meaningful. What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. 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.

Named one of the 100 greatest film books of all time by The Hollywood Reporter, this singular, warm-hearted, inspiring look at life itself is "the best thing Mr. Ebert has ever written" (Janet Maslin, New York Times). "To make ourselves unhappy is where all crime starts. We must try to contribute joy to the world. That is true no matter what our problems, our health, our circumstances. We must try. I didn't always know this, and am happy I lived long enough to find it out." Roger Ebert was the best-known film critic of his time. He began reviewing films for the Chicago Sun-Times in1967, and was the first film critic ever to win a Pulitzer Prize. He appeared on television for four decades. In 2006, complications from thyroid cancer treatment resulted in the loss of his abi)lity to eat, drink, or speak. But with the loss of his voice, Ebert became a more prolific and influential writer. And in Life Itself he told the full, dramatic story of his life and career. In this candid, personal history, Ebert chronicled it all: his loves, losses, and obsessions; his struggle and recovery from alcoholism; his marriage; his politics; and his spiritual beliefs. He wrote about his years at the Sun-Times, his colorful newspaper friends, and his life-changing collaboration with Gene Siskel. He shared his insights into movie stars and directors like John Wayne and Martin Scorsese. This is a story that only Roger Ebert could tell, filled with the same deep insight, dry wit, and sharp observations that his readers have long cherished,
