“Suppose the word mountain meant metaphor, and dog, and Bible, and the United States. Clearly, if a word meant everything, it would mean nothing. If, now, the law of contradiction is an arbitrary convention, and if our linguistic theorists choose some other convention, I challenge them to write a book in conformity with their principles. As a matter of fact it will not be hard for them to do so. Nothing more is necessary than to write the word metaphor sixty thousand times: Metaphor metaphor metaphor metaphor…. This means the dog ran up the mountain, for the word metaphor means dog, ran, and mountain. Unfortunately, the sentence “metaphor metaphor metaphor” also means, Next Christmas is Thanksgiving, for the word metaphor has these meanings as well.”
