In the book Seeing Voices, the author describes the world of the deaf, which he explores with extreme passion. The book begins with the history of deaf people in the United States of America, the horrific ways in which they were viewed and treated, and their ongoing struggle to gain hospitality in the hearing world. Seeing Voices also examines the visual language of the deaf, sign language, which is as expressive and rich as any spoken language. This book covers a variety of topics related to deaf studies, including sign language, the neurology of deafness, the treatment of deaf American citizens throughout history, and the linguistic and social challenges facing the deaf community. In this book, Oliver Sacks does not see deaf people as having a condition that can be cured, but instead sees deaf people more as a racial group. This book is divided into three parts. In the first part, Oliver Sacks makes a strong case for sign language, stating that it is actually a complete language and that it is as complete as English, French, Chinese, and any other spoken language. It also describes the unfortunate history of oralism (this is the education of deaf students through oral language using lip reading, speech and imitation of mouth shapes and breathing patterns of speech)) in the education of deaf children. Furthermore, the first part covers the history of deaf people and information about deafness. Also includes an introduction by the author to the world of the deaf. In the second part the book deals with the vision of American Sign Language and how people naturally created the grammar and arrangement of words and sentences to create well-formed sentences in a language format practically from scratch. It shows that this language... in the middle of the paper... I don't care, probably because of all the footnotes. Another problem I had with this book was all the big scientific words Oliver used. It seemed like jargon to me. Maybe I don't have a large scientific vocabulary. Another thing that bothered me about this book was how difficult it was to find it. It was only in public libraries, not bookstores, and all copies in Contra Costa County had already been checked. We eventually found a copy of the book at the Menlo Park Public Library. Thank goodness my aunt lives nearby and was able to get it for me. I think this book would be a good choice for someone who wants to understand sign language from a scientific perspective or for someone who is taking deaf studies in college. Overall, I give this book a score of seven out of ten, due to the large amount of confusing footnotes, which overall isn't a terrible score..
