Boasian view of language
Definition - As defined by Noam Chomsky, Franz Boas's view of language is: "Languages can differ from one another in arbitrary ways, so when you investigate a new language, you should do it without any preconceptions about what a language can be because they can be entirely different."

Chomsky goes on to say that if Boas' view is true, "there would be no such thing as language; it would be just anything that comes along."
