I am just as deaf as I am blind. The problems of deafness are deeper and more complex, if not more important than those of blindness. Deafness is a much worse misfortune. For it means the loss of the most vital stimulus- the sound of the voice that brings language, sets thoughts astir, and keeps us in the intellectual company of man.
