Looking closely at life at Gallaudet University, Oliver Sacks discovered that knowing something was not the same as understanding it. He knew that sign language enabled communication. Yet seeing people use it in classes, mathematical discussions, and intimate conversation helped him relinquish a persistent assumption: perhaps a language without sound was somehow less complete.
Conversation was plentiful on campus. What was missing was the visiting doctor's ability to follow it. Readers familiar with Sacks may find this reversal striking. Usually a patient comes to a physician who explains an unfamiliar experience. Here he must acknowledge that others already lead rich lives while he remains outside the conversation.
Seeing Voices, published in 1989 and available in Han Wenzheng's Chinese translation, has three parts: Deaf educational history, language and thought, and the 1988 movement demanding a Deaf president at Gallaudet. Sacks was a neurologist, but this is neither an account of hearing organs nor a collection inviting admiration for disabled people's fortitude.
It records a hearing person's revision of his understanding. That revision is not always thorough enough, and parts deserve questioning. We can follow his curiosity without treating his astonishment as the final explanation.
Moving hands do more than mime
People unfamiliar with signing may imagine a collection of mimed actions: an eating gesture means eating, a pointed finger means over there. This leaves a predictable question. Concrete things may be mimed, but how could complex matters be expressed?
Sacks's important shift is to recognize sign as language rather than a temporary replacement for absent speech. American Sign Language, the book's principal example, has its own grammar. It does not substitute a gesture for each English word in sequence. Facial expression, movement, and spatial position can all contribute meaning. Native users do not experience these as decorative additions requiring explanation.
The National Institute on Deafness and Other Communication Disorders likewise describes ASL as a complete natural language with grammar distinct from English. There is no universal sign language. Shared spoken English does not ensure that American and British signers understand each other's languages. A common label cannot erase their histories and differences.
These introductory facts change how a classroom looks. For a student primarily using ASL, learning written English involves another language's rules, not merely recognizing letters. A teacher cannot assume that a student who struggles with a seemingly obvious English sentence lacks the capacity to think. Sometimes another person's difficulty is simply one we have never encountered.
The discussion remains close to everyday judgments. Not hearing, not speaking, and not understanding are easily conflated, as though one implied the others. Sacks separates them. Inability to receive speech through sound does not prevent complex understanding through another language.
Nor need respect take us to the opposite extreme, making sign language more miraculous than spoken language. It too involves learning, ambiguity, misunderstandings, humor, and disagreement. Recognizing its capacity for ordinary, complicated life takes us farther than marveling at extraordinary powers.
Should children understand, or become more like us?
Treating sign as second best can direct education toward making Deaf children speak and lip-read so that they can enter the hearing world. The stated aim is opportunity. But if accessible communication is postponed in the process, the years spent waiting to speak also change what children can learn.
Sacks traces the history of oralism's suppression of sign. The 1880 Milan congress on Deaf education adopted resolutions excluding sign from teaching, with lasting influence. Oralism here means not any use of speech instruction, but its elevation into the almost exclusively legitimate approach. Whether children could produce speech overshadowed a question that should never have become secondary: did they understand the lesson?
A development after the book's publication belongs beside that history. In Vancouver in 2010, the international congress formally rejected the Milan resolutions and expressed regret for their harmful effects. Deaf educators at Gallaudet welcomed the statement while immediately asking what action would follow. Acknowledging a 130-year-old wrong matters; accessible teaching and teachers who can sign still require implementation in schools.
The book's attention to early language experience raises important questions without prescribing an answer for every family today. Hearing, language access, and individual preferences differ. Current professional information emphasizes early access to learnable language and discusses communication options. A 1989 cultural and scientific essay collection cannot replace current educational or clinical assessment.
Teachers' positions change too. A classroom that accepts only expression familiar to hearing educators can exclude Deaf teachers' experience. Recognizing sign as a language of instruction allows people previously treated as recipients of help to become teachers. More than an auxiliary service is added: different people can stand at the front of the room.
Yet teaching and deciding how a school is run remain distinct opportunities. Who sets educational goals and defines progress? In the third part, these questions move from the classroom to the university's governing board.
A university without a Deaf president
By 1988, Gallaudet had 124 years of collegiate history without a Deaf president. Two of the final three candidates that year were Deaf, but the board selected the hearing candidate. Students protested.
From a welfare perspective, the conflict may seem puzzling. The institution exists and students can attend: why such a struggle over its leader? The earlier discussions now acquire a sharper point. An institution can serve people for years while never trusting them to lead it.
The four demands preserved in Gallaudet's history extend beyond replacing the president. They include the board chair's resignation, a Deaf majority on the board, and protection against reprisals for protesting students and employees. Together they concern where decisions are made and whether dissent can be expressed without subsequent punishment, not simply a symbolic appointment.
Sacks visited students organizing and acting. He recorded the encounter's power but also revealed his limits. In a 1990 review, sociologist John B. Christiansen criticized the romanticization of students and the tendency to credit the most visible campus participants with almost the entire achievement.
Read alongside institutional history, the book reveals a longer background of alumni, staff, faculty, and Deaf organizations advocating change. Conditions did not emerge from nothing within a week. Student action mattered profoundly, but less conspicuous people helped make it possible. This does not diminish the movement; it clarifies how change happens.
The movement led to the appointment of I. King Jordan, Gallaudet's first Deaf president. More than eventual recognition deserves remembering. Leadership is not a reward outsiders bestow for good behavior. People seeking a voice in governance need not prove themselves endlessly gentle or grateful. A university teaching independent judgment cannot demand passive acceptance when that judgment is directed at the university itself.
Curiosity also needs checking
Sacks's willingness to be changed by what he sees makes the book compelling. Sometimes, however, unfamiliarity becomes wonder too quickly, as though he has encountered minds fundamentally unlike hearing minds.
Linguist David M. Perlmutter offers specific criticism. He appreciates the introduction to Deaf culture while questioning claims about sign language's distinctive structures and neurological foundations. Signers from different places finding ways to communicate does not demonstrate that their languages share a special principle unavailable to spoken languages. Managing communication and mastering another language are different achievements.
The criticism extends Sacks's own change of perspective. If sign is not deficient speech, respecting it does not require elevating it into an incomparable miracle. Eager admiration can once again conceal actual people and languages behind an attractive image.
Readers can follow the enthusiasm and pause where it outruns evidence. Dense notes open many byways, and history, linguistics, and observation do not always join seamlessly. Treating the book as a serious outsider's learning, still containing misunderstandings, preserves more curiosity than treating it as a complete account of Deaf life.
Back on campus, Sacks can perceive much without directly understanding the conversations. Visitors unfamiliar with a local language routinely encounter this situation. Others need not interrupt their lives to demonstrate their richness. He can instead spend time learning how to join the conversation.
