The question of a special "sixth sense," such as people have ascribed. to Miss Keller, is a delicate one. This much is certain, she cannot have any sense that other people may not have, and the existence of a special sense is not evident to her or to any one who knows her. Miss Keller is distinctly not a singular proof of occult and mysterious theories, and any attempt to explain her in that way fails to reckon with her normality. She is no more mysterious and complex than any other person. All that she is, all that she has done, can be explained directly, except such things in every human being as never can be explained. She does not, it would seem, prove the existence of spirit without matter, or of innate ideas, or of immortality, or anything else that any other human being does not prove. Philosophers have tried to find out what was her conception of abstract ideas before she learned language. If she had any conception, there is no way of discovering it now; for she cannot remember, and obviously there was no record at the time. She had no conception of God before she heard the word "God," as her comments very clearly show. Her sense of time is excellent, but whether it would have developed as a special faculty cannot be known, for she has had a watch since she was seven years old. Miss Keller has two watches, which have been given her. They are, I think, the only ones of their kind in America. The watch has on the back cover a flat gold indicator which can be pushed freely around from left to right until, by means of a pin inside the case, it locks with the hour hand and takes a corresponding position. The point of this gold indicator bends over the edge of the case, round which are set eleven raised points--the stem forms the twelfth. Thus the watch, an ordinary watch with a white dial for the person who sees, becomes for a blind person by this special attachment in effect one with a single raised hour hand and raised figures. Though there is less than half an inch between the points--a space which represents sixty minutes--Miss Keller tells the time almost exactly. It should be said that any double-case watch with the crystal removed serves well enough for a blind person whose touch is sufficiently delicate to feel the position of the hands and not disturb or injure them.
