Voices of Reason, Voices of Insanity: Studies of Verbal Hallucinations
[Leudar and Thomas] are able to establish some useful principles for separating hallucinated voices from usual social discourse. [Voices of Reason, Voices of Insanity] exhibits good cohesiveness...I suspect that it may become a classic of psychological literature.  I would recommend it to anyone who works with individuals who hallucinate..–John J. Haggerty, Jr., M.D., Psychiatric Services, A Journal of the American Psychiatric Association, March 2003This is an extremely interesting book in that it presents an historical overview of the way that voice hearing experiences have been written about, described, experienced and debated. It culminates with recent data that the authors (a psychologist and a psychiatrist) have collected on modern day voice hearers accounts of their voices in terms of pragmatic analysis of their characters.–Journal of Coginitive Psychotherapy: An International Quarterly, Fall 2001
