In the study of Natural Languages one may, for instance, think of a variation of Necessitation by simply saying that if a string or sentence that expresses a proposition is a sentence of a language, then the sentence that expresses that the same proposition is necessary must also be a sentence of the same language. But that would be a very basic and elementary principle of natural language. [READ MORE]
