Voice. SEEING VOICES,

“[I]t is not (usually) the ideas of philosophers that change reality; nor, conversely, is it the practice of ordinary people. What changes history, what kindles revolutions, is the meeting of the two.”
― from SEEING VOICES, Oliver Sacks Foundation

In 'Seeing Voices', Oliver Sacks turns his attention to the subject of deafness, and the result is a deeply felt portrait of a minority struggling for recognition and respect--a minority with its own rich, sometimes astonishing, culture and unique visual language, an extraordinary mode of communication that tells us much about the basis of language in hearing people as well. 'Seeing Voices' is, as Studs Terkel has written, "an exquisite, as well as revelatory, work."
