The Modularity of Mind By Jerry Fodor This study synthesizes current information from the various fields of cognitive science in support of a new and exciting theory of mind. Most psychologists study horizontal processes like memory and information flow; Fodor postulates a vertical and modular psychological organization underlying biologically coherent behaviors. This view of mental architecture is consistent with the historical tradition of faculty psychology while integrating a computational approach to mental processes. One of the most notable aspects of Fodor's work is that it articulates features not only of speculative cognitive architectures but also of current research in artificial intelligence. The Modularity of Mind made "faculty psychology" respectable again and has generated a large literature in psychology, philosophy, and linguistics. Fodor offers brilliant arguments that the mind has special-purpose perceptual and linguistic modules. A central thesis of Fodor's book is that these modules are "informationally encapsulated" – that is, the modules do their work without being able to access the beliefs that the person has. Thus in an important sense perception is theory-neutral, because what you believe will not affect what you see, hear, etc. For a contrasting view, read chapter two of Paul Churchland's Scientific Realism and the Plasticity of Perception. By the way, Fodor's book is brilliant, but don't look for the entertainingly malicious flashes of humor that typify many of his essays. |

The World in Your Head: A Gestalt View of the Mechanism of Conscious Experience By Steven Lehar This book represents a bold assault on one of the greatest unsolved mysteries in science: the nature of consciousness and the human mind. Rather than examining the brain and nervous system to see what they tell us about the mind, this book begins with an examination of conscious experience to see what it can tell us about the brain. Through this analysis, the first and most obvious observation is that consciousness appears as a volumetric spatial void, containing colored objects and surfaces. This reveals that the representation in the brain takes the form of an explicit volumetric spatial model of external reality. The world we see around us therefore is not the real world itself, but merely a miniature virtual-reality replica of that world in an internal representation. In fact the phenomena of dreams and hallucinations clearly demonstrate the capacity of the brain to construct complete virtual worlds even in the absence of sensory input. Perception is therefore somewhat like a guided hallucination, based on sensory stimulation. This insight allows us to examine the world of visual experience not as scientists exploring the external world, but as perceptual scientists examining a rich and complex internal representation. This unique approach to investigating mental function has implications in a wide variety of related fields, including the nature of language and abstract thought, motor control and behavior – as well as to the world of music, art, and dance, showing how the patterns of regularity and periodicity in space and time apparent in those aesthetic domains reflect the periodic basis set of the underlying harmonic resonance representation in the brain. |

Mind Time: The Temporal Factor in Consciousness By Benjamin Libet Our subjective inner life is what really matters to us as human beings – and yet we know relatively little about how it arises. Over a long and distinguished career Benjamin Libet has conducted experiments that have helped us see, in clear and concrete ways, how the brain produces conscious awareness. For the first time, Libet gives his own account of these experiments and their importance for our understanding of consciousness. Most notably, Libet's experiments reveal a substantial delay – the "mind time" of the title – before any awareness affects how we view our mental activities. If all conscious awarenesses are preceded by unconscious processes, as Libet observes, we are forced to conclude that unconscious processes initiate our conscious experiences. Freely voluntary acts are found to be initiated unconsciously before an awareness of wanting to act – a discovery with profound ramifications for our understanding of free will. How do the physical activities of billions of cerebral nerve cells give rise to an integrated conscious subjective awareness? How can the subjective mind affect or control voluntary actions? Libet considers these questions, as well as the implications of his discoveries for the nature of the soul, the identity of the person, and the relation of the non-physical subjective mind to the physical brain that produces it. Rendered in clear, accessible language, Libet's experiments and theories will allow interested amateurs and experts alike to share the experience of the extraordinary discoveries made in the practical study of consciousness. |

The Emperor's New Mind: Concerning Computers, Minds, and the Laws of Physics By Roger Penrose Some love it, some hate it, but The Emperor's New Mind, physicist Roger Penrose's 1989 treatise attacking the foundations of strong artificial intelligence, is crucial for anyone interested in the history of thinking about AI and consciousness. Part survey of modern physics, part exploration of the philosophy of mind, the book is not for casual readers – though it's not overly technical, it rarely pauses to let the reader catch a breath. The overview of relativity and quantum theory, written by a master, is priceless and uncontroversial. The exploration of consciousness and AI, though, is generally considered as resting on shakier ground. Penrose claims that there is an intimate, perhaps unknowable relation between quantum effects and our thinking, and ultimately derives his anti-AI stance from his proposition that some, if not all, of our thinking is non-algorithmic. Of course, these days we believe that there are other avenues to AI than traditional algorithmic programming; while he has been accused of setting up straw robots to knock down, this accusation is unfair. Little was then known about the power of neural networks and behavior-based robotics to simulate (and, some would say, produce) intelligent problem-solving behavior. Whether these tools will lead to strong AI is ultimately a question of belief, not proof, and The Emperor's New Mind offers powerful arguments useful to believer and nonbeliever alike. |

Shadows of the Mind: A Search for the Missing Science of Consciousness By Roger Penrose This book asserts that human consciousness is not necessarily intelligible in terms of computational models. The brain's conscious activity essentially transcends the forms or possibilities of computation. Penrose (mathematics, Oxford) illustrates his thesis via mathematical logic, including detailed discussions of Godel's proposition of incompleteness, Turing's machines and computabilities, quantum mechanics, and microbiology. Eventually, Penrose argues that artificial intelligence and computer-controlled expert systems are capable of assisting local human expertise but will not be able to replace such expertise. Expanding on some of the ideas and concepts proposed in his controversial book, The Emperor's New Mind, Penrose challenges others to reconsider traditional concepts. Some familiarity with mathematical logic or processes will facilitate one's appreciation of this book. Recommended for scholars, specialists, and informed lay readers. |

The Large, the Small and the Human Mind By Roger Penrose Will quantum physics let us reduce consciousness to computation? Roger Penrose says "no" with great force and eloquence in The Large, the Small, and the Human Mind. Prepared as a series of three lectures in Cambridge's Tanner Series on Human Values, the material is both meticulously thought out and informally presented, including many illustrations by Penrose and others. For publication, the author sought out rebuttals and commentary by philosophers Abner Shimony and Nancy Cartwright, as well as his own colleague and occasional rival, the well-known theoretical physicist Stephen Hawking. Penrose then reserves the last word for himself, an author's prerogative. The result is a sharp but polite argument on the nature of thinking and its reducibility. Readers familiar with The Emperor's New Mind and Shadow of the Mind will find the arguments from quantum physics fleshed out in greater detail, but also attacked with good-natured aplomb. Those who missed out on Penrose's older forays into this territory (or are somehow uninterested in the nature of thought) will find this an excellent broad overview of the modern conception of physics, from subatomic shenanigans to the radius of the universe, as well as a stimulating debate among several great modern thinkers. Despite Penrose's certainty that our brains can't be modeled by computational systems – and hence that strong artificial intelligence will remain in science fiction – the argument continues, and will continue for some time. |

The Road to Reality: A Complete Guide to the Laws of the Universe By Roger Penrose If Albert Einstein were alive, he would have a copy of The Road to Reality on his bookshelf. So would Isaac Newton. This may be the most complete mathematical explanation of the universe yet published, and Roger Penrose richly deserves the accolades he will receive for it. That said, let us be perfectly clear: this is not an easy book to read. The number of people in the world who can understand everything in it could probably take a taxi together to Penrose's next lecture. Still, math-friendly readers looking for a substantial and possibly even thrillingly difficult intellectual experience should pick up a copy (carefully – it's over a thousand pages long and weighs nearly 4 pounds) and start at the beginning, where Penrose sets out his purpose: to describe "the search for the underlying principles that govern the behavior of our universe." Beginning with the deceptively simple geometry of Pythagoras and the Greeks, Penrose guides readers through the fundamentals – the incontrovertible bricks that hold up the fanciful mathematical structures of later chapters. From such theoretical delights as complex-number calculus, Riemann surfaces, and Clifford bundles, the tour takes us quickly on to the nature of spacetime. The bulk of the book is then devoted to quantum physics, cosmological theories (including Penrose's favored ideas about string theory and universal inflation), and what we know about how the universe is held together. For physicists, mathematicians, and advanced students, The Road to Reality is an essential field guide to the universe. For enthusiastic amateurs, the book is a project to tackle a bit at a time, one with unimaginable intellectual rewards. |

Consciousness in Four Dimensions: Biological Relativity and the Origins of Thought By Richard Pico In a book that may profoundly alter the modern discourse on mind and influence the practice of neuromedicine, neurobiologist/neuropsychiatrist, Richard M. Pico unveils a revolutionary new approach to understanding consciousness that pinpoints its origins in the brain. Called Biological Relativity, the approach combines the laws of physics – especially Einstein's laws of relativity – to the latest breakthroughs in neuroscience, molecular biology, and computational theory to create a coherent four-dimensional model for explaining the origins of life and the emergence of complex biological systems – from the living cell to the thinking brain. In a fascinating, ambitious narrative that draws upon a lifetime of experimental and clinical work, Dr. Pico tells a riveting story that begins in the imponderably distant past, with the first proto-cell that endured long enough to become its own frame of reference – both structurally and temporally – and culminates with the most complex biological referent system known to science, the human brain. He then elaborates his groundbreaking theory through discussions of such things as the origins of language, music, and mathematics. He explains why he believes consciousness is uniquely human, and explores the causes and potential treatments for a variety of thought disorders. |

How the Mind Works By Steven Pinker Why do fools fall in love? Why does a man's annual salary, on average, increase $600 with each inch of his height? When a crack dealer guns down a rival, how is he just like Alexander Hamilton, whose face is on the ten-dollar bill? How do optical illusions function as windows on the human soul? Cheerful, cheeky, occasionally outrageous MIT psychologist Steven Pinker answers all of the above and more in his marvelously fun, awesomely informative survey of modern brain science. Pinker argues that Darwin plus canny computer programs are the key to understanding ourselves – but he also throws in apt references to Star Trek, Star Wars, The Far Side, history, literature, W. C. Fields, Mozart, Marilyn Monroe, surrealism, experimental psychology, and Moulay Ismail the Bloodthirsty and his 888 children. If How the Mind Works were a rock show, tickets would be scalped for $100. This book deserved its spot as Number One on bestseller lists. |

The Blank Slate: The Modern Denial of Human Nature By Steven Pinker In his last outing, How the Mind Works, the author of the well-received The Language Instinct made a case for evolutionary psychology or the view that human beings have a hard-wired nature that evolved over time. This book returns to that still-controversial territory in order to shore it up in the public sphere. Drawing on decades of research in the "sciences of human nature," Pinker, a chaired professor of psychology at MIT, attacks the notion that an infant's mind is a blank slate, arguing instead that human beings have an inherited universal structure shaped by the demands made upon the species for survival, albeit with plenty of room for cultural and individual variation. For those who have been following the sciences in question including cognitive science, neuroscience, behavioral genetics and evolutionary psychology much of the evidence will be familiar, yet Pinker's clear and witty presentation, complete with comic strips and allusions to writers from Woody Allen to Emily Dickinson, keeps the material fresh. What might amaze is the persistent, often vitriolic resistance to these findings Pinker presents and systematically takes apart, decrying the hold of the "blank slate" and other orthodoxies on intellectual life. He goes on to tour what science currently claims to know about human nature, including its cognitive, intuitive and emotional faculties, and shows what light this research can shed on such thorny topics as gender inequality, child-rearing and modern art. Pinker's synthesizing of many fields is impressive but uneven, especially when he ventures into moral philosophy and religion; examples like "Even Hitler thought he was carrying out the will of God" violate Pinker's own principle that one should not exploit Nazism "for rhetorical clout." For the most part, however, the book is persuasive and illuminating. |

Words and Rules: The Ingredients of Language By Steven Pinker MIT linguist Pinker builds on his previous successes (How the Mind Works; The Language Instinct) with another book explaining how we learn and deploy word, phrase and utterance. Some linguists (notably Noam Chomsky) have argued that everything in speech comes from hidden, hard-wired rules. Others (notably some computer scientists) claim that we learn language by association, picking up raw data first. Pinker argues that our brains exhibit both kinds of thought, and that we can see them both in English verbs: rule application ("combination") governs regular verbs, memory ("lookup") handles irregulars. The interplay of the two characterizes all language, perhaps all thought. Each of Pinker's 10 chapters takes up a different field of research, but all 10 concern regular and irregular forms of words. Pinker shows what scientists learn from children's speech errors (My brother got sick and pukeded); from survey questions (What do you call more than one wug?); from similar rules in varying languages (English, German and Arapesh); from theoretical models and their failings and from brain disorders like jargon anomia (whose victims use complex sentences, but say things like "nose cone" when they mean "phone call"). Sometimes Pinker explains linguists' current consensus; at other times, he makes a case for his own theoretical school. His previous books have been accused of excessive ambition; here he largely sticks to his own fields. The result, with its crisp prose and neat analogies, makes required reading for anyone interested in cognition and language. |
