Plann shows how changing conceptions of deafness and language constantly influenced deaf instruction. Nineteenth-century advances brought new opportunities for deaf students, but at the end of what she calls the preprofessional era of deaf education, deaf people were disempowered because they were barred from the teaching profession. The Spanish deaf community to this day shows the effects of the exclusion of deaf teachers for the deaf.
The questions raised by Plann's narrative extend well beyond the history of deaf education in Spain: they apply to other minority communities and deaf cultures around the world. At issue are the place of minority communities within the larger society and, ultimately, our tolerance for human diversity and cultural pluralism.
