Dr. Lesk Dr. Lesk has been a practicing, board-certified psychiatrist since 1984, treating thousands of adult patients while researching, writing articles and mentoring students. He served as chairman of psychiatry at a large VA hospital in New York and assistant professor at the affiliated medical school. He is pioneering new theories in hopes of improving our understanding of the illnesses patients endure and reducing stigma while surging empathy. This book is a result of those efforts. Unlike any other work in the field, Dr. Lesk’s ‘primitive organization’ theory explains the phenomenon of schizophrenia with advanced, scientifically documented clarity and depth, opening a fresh window on mental illness while weaving together disciplines as diverse as Darwinian evolution, anthropology, physics, neurochemistry and Freudian psychology in a lucid panorama.
