Drawing on the latest work in cognitive neuroscience, a philosopher proposes that delusions are narrative models that accommodate anomalous experiences. In The Measure of Madness, Philip Gerrans offers a novel explanation of delusion. Over the last two decades, philosophers and cognitive scientists have investigated explanations of delusion that interweave philosophical questions about the nature of belief and rationality with findings from cognitive science and neurobiology. Gerrans argues that once we fully describe the computational and neural mechanisms that produce delusion and the way in which conscious experience and thought depend on them, the concept of delusional belief retains only a heuristic role in the explanation of delusion. Gerrans proposes that delusions are narrative models that accommodate anomalous experiences. He argues that delusions represent the operation of the Default Mode Network (DMN)—the cognitive system that provides the raw material for humans' inbuilt tendency to provide a subjectively compelling narrative context for anomalous or highly salient experiences—without the “supervision” of higher cognitive processes present in the nondelusional mind. This explanation illuminates the relationship among delusions, dreams, imaginative states, and irrational beliefs that have perplexed philosophers and psychologists for over a century. Going beyond the purely conceptual and the phenomenological, Gerrans brings together findings from different disciplines to trace the flow of information through the cognitive system, and applies these to case studies of typical schizophrenic delusions: misidentification, alien control, and thought insertion. Drawing on the interventionist model of causal explanation in philosophy of science and the predictive coding approach to the mind influential in computational neuroscience, Gerrans provides a model for integrative theorizing about the mind.
This book applies a powerful framework in computational neuroscience (predictive coding and active inference) to explain psychiatric disorders that are characterised by pathologies of self-awareness. It shows how the self is best conceived of as an avatar or model made by the brain for the fundamental purpose of optimising basic bodily function. That avatar integrates and coordinates neurocomputation across the mind. It allows the mind to anticipate and respond to sensory information that bears on the organism’s prospects. The self is thus a model (avatar) made by the brain to allow the body to play the game of life. When activity in circuitry that implements the avatar is compromised a variety of psychiatric disorders result. Anatomy of an Avatar provides a theoretical framework for theories of embodied selfhood anchored in homoestatic regulation, as well as exploring psychiatric disorders involving the self and the empirical application of concepts of free energy minimisation, active inference and predictive processing. The book also includes key case studies in the cognitive neuropsychiatry of self awareness and test cases for philosophical concepts of self representation and the experience of self awareness. The book will be essential reading for those in the fields of psychology and consciousness, psychiatry, and philosophy.
