There are hundreds of instances where the deaf have undergone battles, shipwrecks or other frightful adventures with composure, while their companions were stumbling or jabbering with fear. These latter would tell you that the most horrible part of their experience was the cries of the suffering who faced death in agony and fear. The mere spectacle of the suffering did not upset the cool judgment of the deaf. It seems evident that sound also has a greater stimulating effect upon the emotions of animals than do the other senses. A friend who has studied this subject says: “I have imitated different animals many thousand times, and can easily deceive them at their own game, but cannot long deceive the average person. A dog relying on sight, smell and hearing—and maybe a little, a very little reasoning—although he may be very brave—can easily be made to flee in terror by the right sort of growling and noises connecting first wonder, then anger or terror. He hears a very ferocious dog, but can neither see nor smell him; here is something new, which he cannot reason out—he curls his tail, gives a frightened yelp, registers fear in other ways and runs with all his might. “Recently I was out hunting wild turkeys, and had nearly induced one to come near to me when a stick fell from a tree, and without waiting to reason, away he went. My call would not deceive a person, but any sort of an amateur squawk easily deceives a gobbler. Not long ago, a friend of mine, while calling a gobbler, called also a wildcat who was trying to get the gobbler for breakfast. Animal sight may be ultra-human, but I am very sure that animal hearing is not.” Doubtless we all rely on hearing to keep us informed concerning the fear instinct. Children hear a great deal subjectively, aided by their fears plus imagination. I am almost prepared to state that deafness is connected with fearlessness above the average, but I am not yet sure of my ground. Any defect of the five senses strengthens in a measure the remaining channels, and deafness cannot but assist concentration in those persons of studious contemplative habit, since it closes one avenue of interruption. I have noticed that with those of a philosophical turn plus strong will—or won’t—deafness saves nerve fatigue, from hearing many noises or remarks. I have observed the habits of several deaf cats and dogs, and have noted instances of exceptional bravery, and evidences of a new sense, probably the substitute for the one they have lost. Some of my own experiences also show how sound dominates physical fear.
