Paul Thagard is professor of philosophy, psychology, and computer science at the University of Waterloo, Canada. His previous books include Mind: Introduction to Cognitive Science and Hot Thought: Mechanisms and Applications of Emotional Cognition.

[Thagard] offers a tightly reasoned, often humorous, and original contribution to the emerging practice of applying science to areas heretofore the province of philosophers, theologians, ethicists, and politicians: What is reality and how can we know it? Are mind and brain one or two? What is the source of the sense of self? What is love? What is the difference between right and wrong, and how can we know it? What is the most legitimate form of government? What is the meaning of life, and how can we find happiness in it? Thagard employs the latest tools and findings of science in his attempts to answer these (and additional) questions. -- Michael Shermer, Science A thoughtful and well-researched attempt to answer that most fundamental existential question: why not kill yourself? Or, to give it a positive spin, what gives life meaning? Thagard lays out detailed arguments that reality is knowable through science, that minds are nothing other than material brains and that there are no ultimate rights and wrongs handed down by a supernatural being. -- New Scientist Thagard's 'neural naturalism' promises nothing short of a conceptual revolution, or better, a paradigm shift. His evidence-based strategy uses the data from psychology and neuroscience to expose empirically based answers to questions such as, What is the meaning of life? What ought one to do? ... Thagard's reader-friendly text includes a glossary, endnotes, and extensive references. -- Choice The name of this well-written and ambitious book understates the breadth of its scope. The book deals with the relation of modern neuroscience not only to the meaning of life, but also to ethics, metaphysics, and epistemology... The discussion is rich, unorthodox, and frequently exciting. -- Iddo Landau, Metapsychology Online Reviews The book integrates decades of multidisciplinary research, but its clear explanations and humor make it accessible to the general reader. -- Gaia Media News [R]eaders will find much of the
