This book is an analysis and discussion of the soul as a psychophysical process and its role in mental representation, meaning, understanding and agency. Grant Gillett and Walter Glannon combine contemporary neuroscience and philosophy to address fundamental issues about human existence and living and acting in the world. Based in part on Aristotle's hylomorphism and model of the psyche, their approach is informed by a neuroscientific model of the brain as a dynamic organ in which patterns of neural oscillation and synchronization are shaped by biological, social and cultural factors inside and outside of it. The authors provide a richer and more robust account of the soul, or mind, than other accounts by framing it in neuroscientific and philosophical terms that do not explain it away but explain it as something that is shaped by how it responds to the natural and social environment in enabling flexible and adaptive behavior.
