................... If the foot should say ''because I am not a hand, I do not belong to the body,'' it would not for that reason cease to be part of the body. And if the ear should say ''Because I am not an eye, I do not belong to the body'' it would not for that reason cease to be part of the body. If the whole body were an eye where would the sense of hearing be? If the whole body were an ear where would the sense of smell be?
