The experience of 'hearing voices', once associated with lofty prophetic communications, has fallen low. Today, the experience is typically portrayed as an unambiguous harbinger of madness caused by a broken brain, an unbalanced mind, biology gone wild. Yet an alternative account, forged predominantly by people who hear voices themselves, argues that hearing voices is an understandable response to traumatic life-events. There is an urgent need to overcome the tensions between these two ways of understanding 'voice hearing'.

Simon McCarthy-Jones considers neuroscience, genetics, religion, history, politics and not least the experiences of many voice hearers themselves. This enables him to challenge established and seemingly contradictory understandings and to create a joined-up explanation of voice hearing that is based on evidence rather than ideology.
