"An honest attempt to compare and analyze the intelligence of humans, animals, and computers by an eminent cognitive scientist and long-time Press author"--

Living is a balancing act. Ordinary activities like walking, running, or riding a bike require the brain to keep the body in balance. A dancer's poised elegance and a tightrope walker's breathtaking performance are feats of balance. Language abounds with expressions and figures of speech that invoke balance. People fret over work-life balance or try to eat a balanced diet. The concept crops up from politics-checks and balances, the balance of power, balanced budgets-to science, in which ideas of equilibrium are crucial. Why is balance so fundamental, and how do physical and metaphorical balance shed light on each other?Paul Thagard explores the physiological workings and metaphorical resonance of balance in the brain, the body, and society. He describes the neural mechanisms that keep bodies balanced and explains why their failures can result in nausea, falls, or vertigo. Thagard connects bodily balance with leading ideas in neuroscience, including the nature of consciousness. He analyzes balance metaphors across science, medicine, economics, the arts, and philosophy, showing why some aid understanding but others are misleading or harmful. Thagard contends that balance is ultimately a matter of making sense of the world. In both literal and metaphorical senses, balance is what enables people to solve the puzzles of life by turning sensory signals or an incongruous comparison into a coherent whole.Bridging philosophy, psychology, and neuroscience, Balance shows how an unheralded concept's many meanings illuminate the human condition.

An expert on mind considers how animals and smart machines measure up to human intelligence.Octopuses can open jars to get food, and chimpanzees can plan for the future. An IBM computer named Watson won on Jeopardy! and Alexa knows our favorite songs. But do animals and smart machines really have intelligence comparable to that of humans? In Bots and Beasts, Paul Thagard looks at how computers ("bots") and animals measure up to the minds of people, offering the first systematic comparison of intelligence across machines, animals, and humans. Thagard explains that human intelligence is more than IQ and encompasses such features as problem solving, decision making, and creativity. He uses a checklist of twenty characteristics of human intelligence to evaluate the smartest machines--including Watson, AlphaZero, virtual assistants, and self-driving cars--and the most intelligent animals--including octopuses, dogs, dolphins, bees, and chimpanzees. Neither a romantic enthusiast for nonhuman intelligence nor a skeptical killjoy, Thagard offers a clear assessment. He discusses hotly debated issues about animal intelligence concerning bacterial consciousness, fish pain, and dog jealousy. He evaluates the plausibility of achieving human-level artificial intelligence and considers ethical and policy issues. A full appreciation of human minds reveals that current bots and beasts fall far short of human capabilities.

Ranging through the history of medicine, from the Hippocratic theory of humors to modern explanations of Mad Cow Disease and chronic fatigue syndrome, this book analyzes the development and acceptance of scientific ideas. It challenges both traditional philosophy of science and contemporary science studies.

Psychology is the study of thinking, and cognitive science is the interdisciplinary investigation of mind and intelligence that also includes philosophy, artificial intelligence, neuroscience, linguistics, and anthropology. This book illuminates the nature of the theories and explanations used in the investigation of minds.

Draws on the history and philosophy of science, cognitive psychology, and the field of artificial intelligence to develop a theory of conceptual change capable of accounting for all major scientific revolutions. This book provides a comprehensive perspective on the transformation of scientific conceptual systems.

Why is life worth living? What makes actions right or wrong? What is reality and how do we know it? The Brain and the Meaning of Life draws on research in philosophy, psychology, and neuroscience to answer some of the most pressing questions about life's nature and value. Paul Thagard argues that evidence requires the abandonment of many traditional ideas about the soul, free will, and immortality, and shows how brain science matters for fundamental issues about reality, morality, and the meaning of life. The ongoing Brain Revolution reveals how love, work, and play provide good reasons for living. Defending the superiority of evidence-based reasoning over religious faith and philosophical thought experiments, Thagard argues that minds are brains and that reality is what science can discover. Brains come to know reality through a combination of perception and reasoning. Just as important, our brains evaluate aspects of reality through emotions that can produce both good and bad decisions. Our cognitive and emotional abilities allow us to understand reality, decide effectively, act morally, and pursue the vital needs of love, work, and play. Wisdom consists of knowing what matters, why it matters, and how to achieve it. The Brain and the Meaning of Life shows how brain science helps to answer questions about the nature of mind and reality, while alleviating anxiety about the difficulty of life in a vast universe. The book integrates decades of multidisciplinary research, but its clear explanations and humor make it accessible to the general reader.
