“Dottor Marcuccio, who was also blind as a result of an accident, […] had explained to her that darkness was a visual sensation and therefore a prerogative of those who have the gift of sight. ‘The blind […] cannot see the darkness, just as the deaf cannot hear silence, which is an auditory sensation, the antithesis of sound; that’s all there is to it.’”
