What is the origin of meaning? How does the brain achieve symbolic computation? What are the neural correlates of cognitive processes? These challenging questions at the borderline between neuroscience, cognitive science, nonlinear dynamics, and philosophy are related to the symbol grounding problem: How is the meaning of words and utterances grounded in the dynamics of the brain and in the evolution of beings alive interacting with each other and with their environments? Simply by convention? Or is there an inherent correctness of names, of syllables, or even of sounds? This new book examines these important issues and presents probing analyses of the latest research.
