Above all don’t use the word good as though it meant something in evolutionary science. The Hard Problem is a tour de force, exploring fundamental questions of how we experience the world, as well as telling the moving story of a young woman whose struggle for understanding her own life and the lives of others leads her to question the deeply held beliefs of those around her. Hilary, a young psychology researcher at the Krohl Institute for Brain Science, is nursing a private sorrow and a troubling question. She and other researchers at the institute are grappling with what science calls the “hard problem”—if there is nothing but matter, what is consciousness? What Hilary discovers puts her fundamentally at odds with her colleagues, who include her first mentor and one-time lover, Spike; her boss, Leo; and the billionaire founder of the institute, Jerry. Hilary needs a miracle, and she is prepared to pray for one.
A Blueprint for the Hard Problem of Consciousness addresses the fundamental mechanism that allows physical events to transcend into subjective experiences, termed the Hard Problem of Consciousness. Consciousness is made available as the abstract product of self-referent realization of information by strange loops through the levels of processing of the brain. Readers are introduced to the concept of the Hard Problem of Consciousness and related concepts followed by a critical discourse of different theories of consciousness. Next, the author identifies the fundamental flaw of the Integrated Information Theory (IIT) and proposes an alternative that avoids the cryptic intelligent design and panpsychism of the IIT. This author also demonstrates how something can be created out of nothing without resorting to quantum theory, while pointing out neurobiological alternatives to the bottom-up approach of quantum theories of consciousness. The book then delves into the philosophy of qualia in different physiological knowledge networks (spatial, temporal and olfactory, cortical signals, for example) to explain an action-based model consistent with the generational principles of Predictive Coding, which maps prediction and predictive-error signals for perceptual representations supporting integrated goal-directed behaviors. Conscious experiences are considered the outcome of abstractions realized out of map overlays and provided by sustained oscillatory activity. The key feature of this blueprint is that it offers a perspective of the Hard Problem of Consciousness from the point of view of the subject; the experience of ‘being the subject’ is predicted to be the realization of inference inversely mapped out of hidden causes of global integrated actions. The author explains the consistencies of his blueprint with ideas of the Global Neuronal Workspace and the Adaptive Resonance Theory of consciousness as well as with the empirical evidence supporting the Integrated Information Theory. A Blueprint for the Hard Problem of Consciousness offers a unique perspective to readers interested in the scientific philosophy and cognitive neuroscience theory in relation to models of the theory of consciousness.
A noted philosopher proposes a naturalistic (rather than supernaturalistic) way to solve the "really hard problem": how to live in a meaningful way—how to live a life that really matters—even as a finite material being living in a material world. If consciousness is "the hard problem" in mind science—explaining how the amazing private world of consciousness emerges from neuronal activity—then "the really hard problem," writes Owen Flanagan in this provocative book, is explaining how meaning is possible in the material world. How can we make sense of the magic and mystery of life naturalistically, without an appeal to the supernatural? How do we say truthful and enchanting things about being human if we accept the fact that we are finite material beings living in a material world, or, in Flanagan's description, short-lived pieces of organized cells and tissue? Flanagan's answer is both naturalistic and enchanting. We all wish to live in a meaningful way, to live a life that really matters, to flourish, to achieve eudaimonia—to be a "happy spirit." Flanagan calls his "empirical-normative" inquiry into the nature, causes, and conditions of human flourishing eudaimonics. Eudaimonics, systematic philosophical investigation that is continuous with science, is the naturalist's response to those who say that science has robbed the world of the meaning that fantastical, wishful stories once provided. Flanagan draws on philosophy, neuroscience, evolutionary biology, and psychology, as well as on transformative mindfulness and self-cultivation practices that come from such nontheistic spiritual traditions as Buddhism, Confucianism, Aristotelianism, and Stoicism, in his quest. He gathers from these disciplines knowledge that will help us understand the nature, causes, and constituents of well-being and advance human flourishing. Eudaimonics can help us find out how to make a difference, how to contribute to the accumulation of good effects—how to live a meaningful life.
At the 1994 landmark conference "Toward a Scientific Basis for Consciousness", philosopher David Chalmers distinguished between the "easy" problems and the "hard" problem of consciousness research. According to Chalmers, the easy problems are to explain cognitive functions such as discrimination, integration, and the control of behavior; the hard problem is to explain why these functions should be associated with phenomenal experience. Why doesnt all this cognitive processing go on "in the dark", without any consciousness at all? In this book, philosophers, physicists, psychologists, neurophysiologists, computer scientists, and others address this central topic in the growing discipline of consciousness studies. Some take issue with Chalmers' distinction, arguing that the hard problem is a non-problem, or that the explanatory gap is too wide to be bridged. Others offer alternative suggestions as to how the problem might be solved, whether through cognitive science, fundamental physics, empirical phenomenology, or with theories that take consciousness as irreducible.

Daniel Dennett's "brilliant" exploration of human consciousness — named one of the ten best books of the year by the New York Times — is a masterpiece beloved by both scientific experts and general readers (New York Times Book Review). Consciousness Explained is a full-scale exploration of human consciousness. In this landmark book, Daniel Dennett refutes the traditional, commonsense theory of consciousness and presents a new model, based on a wealth of information from the fields of neuroscience, psychology, and artificial intelligence. Our current theories about conscious life — of people, animal, even robots — are transformed by the new perspectives found in this book. "Dennett is a witty and gifted scientific raconteur, and the book is full of fascinating information about humans, animals, and machines. The result is highly digestible and a useful tour of the field." —Wall Street Journal

How does conscious experience arise out of the functioning of the human brain? How is it related to the behaviour that it accompanies? How does the perceived world relate to the real world? Between them, these three questions constitute what is commonly known as the Hard Problem of consciousness. Despite vast knowledge of the relationship between brain and behaviour, and rapid advances in our knowledge of how brain activity correlates with conscious experience, the answers to all three questions remain controversial, even mysterious. This important new book analyses these core issues and reviews the evidence from both introspection and experiment. To many its conclusions will be surprising and even unsettling: · The entire perceived world is constructed by the brain. The relationship between the world we perceive and the underlying physical reality is not as close as we might think. · Much of our behaviour is accomplished with little or no participation from conscious experience. · Our conscious experience of our behaviour lags the behaviour itself by around a fifth of a second - we become aware of what we do only after we have done it. · The lag in conscious experience applies also to the decision to act - we only become aware of our decisions after they have been formed. · The self is as much a creation of the brain as is the rest of the perceived world. Written by a leading scientist, this analysis of how conscious experience relates to brain and behaviour is accessible and compelling. It will have major implications for our understanding of human nature.
An intriguing new scientific theory that explains what life is and how it emerges. What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is. This is an urgent issue for efforts to make life from scratch in laboratories here on Earth and missions searching for life on other planets. Walker proposes a new paradigm for understanding what physics encompasses and what we recognize as life. She invites us into a world of maverick scientists working without a map, seeking not just answers but better ways to formulate the biggest questions we have about the universe. The book culminates with the bold proposal of a new theory for identifying and classifying life, one that applies not just to biological life on Earth but to any instance of life in the universe. Rigorous, accessible, and vital, Life as No One Knows It celebrates the mystery of life and the explanatory power of physics.
This book tackles the most difficult and profound open questions about life and its origins from an information-based perspective.
The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility.
