Hallucinations must have some innate structure in the nervous system underlying them. We can see this clearly by studying the matter in those who have been profoundly deaf since birth or very early childhood. For even they can - somehow - experience auditory hallucinations. This is commonly seen in deaf schizophrenics. In one study, 16 out of 22 hallucinating, profoundly deaf schizophrenics insisted they had heard some kind of communication. One thirty-two-year-old woman, born deaf, who was full of self-recrimination about a therapeutic abortion, claimed she heard accusations from God. Another, a fifty-year-old congenitally deaf woman, heard supernatural voices which proclaimed her to have occult powers.
