A recent wave of research in psychiatry and neuroscience has re-examined the properties of “classic” psychedelic substances - also known as serotonergic hallucinogens - such as psilocybin, LSD, and DMT. Evidence to date suggests that psychedelics can be given safely in controlled conditions, at moderate to high doses, and may have potential as therapeutic agents in the treatment of various addictive and mood disorders. The main mechanism of action appears to be the induction of a dramatically altered state of consciousness, but the details of how psychedelic-assisted psychotherapy works are hotly debated, as are the relations between psychedelic experiences themselves and the neural changes induced by the drugs. Philosophical Perspectives on Psychedelic Psychiatry addresses the fascinating philosophical questions raised by the renewed psychiatric use of psychedelics, with chapters from leading philosophers of mind, science, and psychiatry centred around three main themes. Chapters in the “self and mind” section ask: what can we learn about the self and the mind from psychedelic science? Chapters in the “science and psychiatry” section address methodological, theoretical, and clinical questions concerning how psychedelics can best be studied scientifically and used therapeutically, and how they might work to relieve psychiatric suffering. Finally, chapters in the “ethics and spirituality” section address broader questions about the interpretation of psychedelic experience, its ethical implications, and its possible role(s) in the broader culture.

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.
