"People often say that blindness sharpens hearing, but I don't think this is so. My ears were hearing no better, but I was making better use of them. Sight is a miraculous instrument offering us all the riches of physical life. But we get nothing in this world without paying for it, and in return for all the benefits that sight brings we are forced to give up others whose existence we don't even suspect. These were the gifts I received in such abundance."
