Sapir-Whorf Hypothesis

"Human beings do not live in the objective world alone, nor alone in the world of social activity as ordinarily understood, but are very much at the mercy of the particular language which has become the medium of expression for their society. It is quite an illusion to imagine that one adjusts to reality essentially without the use of language and that language is merely an incidental means of solving specific problems of communication and reflection. The fact of the matter is that the ''real world'' is to a large extent unconsciously built up on the language habits of the group."
(Edward Sapir, Benjamin Lee Whorf)
