Like "The Man Who Mistook His Wife for a Hat" and "An Anthropologist on Mars," in this book Oliver Sacks embarks on an enticing journey to an unknown land of wonders, as well as a challenging reflection on communication, biology, adaptation, and culture.

In "Seeing Voices," Sacks focuses his attention on the issue of deafness, and the result is a heartfelt illustration of a minority that struggles for recognition and respect - a minority with its own rich culture and unique visual language, a wonderful way of communicating that sheds light on the foundations of language not only for the deaf but also for the hearing.

"Seeing Voices" is an "excellent, as well as revelatory study."
