Psychiatry maintains the voices schizophrenics hear are meaningless auditory hallucinations caused by a chemical imbalance in the brain. Clinical investigation into the matter reveals this to be a false claim. Dr. Wilson Van Dusen, a clinical psychologist and author of "The Presence of Spirits in Madness" began holding coherent conversations with the voices of his schizophrenic patients decades ago. He discovered they precisely matched what Christian Mystic Emanuel Swedenborg described as evil spirits. Following up with scores of investigative interviews with his schizophrenic patients, Jerry Marzinsky, a psychiatric evaluator, verified Van Dusen's astonishing conclusion: the voices are real. They are conscious, parasitic entities.
