Summary

Summary

It may be the deepest mystery of philosophy, psychology, and neuroscience: how does the brain unite to create the self, the subjective "I"? In Altered Egos, Dr. Todd Feinberg presents a new theory of the self, based on his first-hand experience as both a psychiatrist and neurologist. Feinberg first introduces the reader to dozens of intriguing cases of patients whose disorders have resulted in what he calls "altered egos": a change in the brain that transforms the boundaries of the self. He describes patients who suffer from "alien hand syndrome" where one hand might attackthe patient's own throat, patients with frontal lobe damage who invent fantastic stories about their lives, paralyzed patients who reject and disown one of their limbs. Feinberg argues that the brain damage suffered by these people has done more than simply impair certain functions--it hasfragmented their sense of self. After illustrating how these patients provide a window into the self and the mind, the author presents a new model of the self that links the workings of the brain with unique and personal features of the mind, such as meaning, purpose, and being. Drawing on his ownand other evidence, Feinberg explains how the unified self, while not located in one or another brain region, arises out of the staggering complexity and number of the brain's component parts. Lucid, insightful, filled with fascinating case studies and provocative new ideas, Altered Egos promises to change the way we think about human consciousness and the creation and maintenance of human identity.

Booklist Review

Feinberg is a neurologist whose treatment of patients with bizarre mental illnesses has led him to ponder that sense of mental unity we call experience. As brain research has progressed, that sense has remained stubbornly resistant to explication; indeed, it has grown more mysterious even as the anatomy of the living brain has become well understood. Feinberg frequently iterates this paradox before propounding his answer to it; before then, he recounts patients who exhibited, following an injury to their brains, a drastic degradation in self-awareness. Previously ordinary people can no longer recognize themselves in mirrors; believe that their limbs belong to somebody else; and, if blinded, insist their vision is 20/20. To Feinberg, these symptoms reinforce his impression of the self's malleability and initiate his argument, with references to Descartes, about how the brain shapes the self. He offers, after refuting notions that the organ has a locus for the self as it does for vision, a version of the self-as-emergent-phenomenon idea. Avoiding undue technical jargon, Feinberg's presentation ably elucidates for general readers the material/ethereal nexus of self-perception. --Gilbert Taylor
