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.

How do minds make societies, and how do societies change? Paul Thagard systematically connects neural and psychological explanations of mind with major social sciences (social psychology, sociology, politics, economics, anthropology, and history) and professions (medicine, law, education, engineering, and business). Social change emerges from interacting social and mental mechanisms. Many economists and political scientists assume that individuals make rational choices, despite the abundance of evidence that people frequently succumb to thinking errors such as motivated inference. Much of sociology and anthropology is taken over with postmodernist assumptions that everything is constructed on the basis of social relations such as power, with no inkling that these relations are mediated by how people think about each other. Mind-Society displays the interdependence of the cognitive and social sciences by describing the interconnections among mental and social mechanisms, which interact to generate social changes ranging from marriage patterns to wars. Validation comes from detailed studies of important social changes, from norms about romantic relationships to economic practices, political institutions, religious customs, and international relations. This book belongs to a trio that includes Brain-Mind: From Neurons to Consciousness and Creativity and Natural Philosophy: From Social Brains to Knowledge, Reality, Morality, and Beauty. They can be read independently, but together they make up a Treatise on Mind and Society that provides a unified and comprehensive treatment of the cognitive sciences, social sciences, professions, and humanities.

Misinformation is one of the twenty-first century’s greatest challenges, a peril to democracy, peace, science, and public health. Yet we lack a clear understanding of what makes misinformation so potent and why it can spread so rapidly. In Falsehoods Fly, a leading cognitive scientist and philosopher offers a new framework for recognizing and countering misleading claims by exploring the ways that information works—and breaks down.Paul Thagard examines the dangers of misinformation on COVID-19, climate change, conspiracy theories, inequality, and the Russian invasion of Ukraine. He argues that effective responses to these problems require understanding how information is generated and spread. Bringing together empirical findings about the psychological and social mechanisms that drive cognitive errors with philosophical accounts of critical thinking, Thagard develops an innovative theory of how we gain information. Grasping how the generation and transmission of knowledge can fail helps us find ways to repair it and provides tools for converting misinformation into facts. Offering a deep and rich account of the nature and workings of information, Falsehoods Fly provides practical, concrete strategies to stop the creation and spread of misinformation.

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.

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.

In this path-breaking work, Paul Thagard 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. The history of science contains dramatic episodes of revolutionary change in which whole systems of concepts have been replaced by new systems. Thagard provides a new and comprehensive perspective on the transformation of scientific conceptual systems. Thagard examines the Copernican and the Darwinian revolutions and the emergence of Newton's mechanics, Lavoisier's oxygen theory, Einstein's theory of relativity, quantum theory, and the geological theory of plate tectonics. He discusses the psychological mechanisms by which new concepts and links between them are formed, and advances a computational theory of explanatory coherence to show how new theories can be judged to be superior to previous ones.

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.
