A brief account of Johnson's own intellectual journey, through which we track some of the most important discoveries in the field over the past forty years, sets the stage. Subsequent chapters set out Johnson's important role in embodied cognition theory, including his cofounding (with George Lakoff) of conceptual metaphor theory and, later, their theory of bodily structures and processes that underlie all meaning, conceptualization, and reasoning. A detailed account of how meaning arises from our physical engagement with our environments provides the basis for a nondualistic, nonreductive view of mind that he sees as most congruous with the latest cognitive science. A concluding section explores the implications of our embodiment for our understanding of knowledge, reason, and truth. The resulting book will be essential for all philosophers dealing with mind, thought, and language.
