“Language has great difficulty in locating sound and finds it hard to testify to its existence. The name “the sound of airplanes landing” is not the sounds name, it is the landing airplanes attribute, and thus I cannot place the validity of the thing of the sound in it, I can not make it an object. “The sound of the airplane” has the function of making us aware of the airplane overhead, that is however not the function of the sound, it is the function of the name “the sound of the airplane”. The sound itself has no function, and so my experience of it, once we disregard the significance of its source, is much harder to locate, and harder even to articulate in language”
