Nearly half of Voices of Reason, Voices of Insanity: Studies of Verbal Hallucinations is devoted to a retrospective examination of famous cases of voice hearing taken from historical, literary, and psychological sources, including Socrates, Achilles, Schreber, and Janet's patient Marcelle. The authors add several contemporary cases from their own experience. Additional chapters explore academic understandings of auditory hallucinations taken from pragmatic psychology and clinical psychiatry and public dialogue on hallucinations as manifested in the British national press. Although the authors include a discussion of hallucinations as psychopathology, they clearly state their intent to remain neutral on the question of whether auditory hallucinations are necessarily a manifestation of mental illness. The analytic tools they use to examine their case material derive as much from philosophical psychiatry as from clinical psychiatry. Linguistic analyses are applied to some of the contemporary cases. Recent neuropsychiatric findings related to auditory hallucinations are briefly noted but are not discussed at length.
