Orwell said that language makes humans easy to control—control their language and you control the people. Language is central to our experience of being human, and the languages we speak profoundly shape the way we think, the way we see the world, the way we live our lives. An ongoing debate in the field of linguistics is whether language is controlled by thought, or thought by language. Edward Sapir and Benjamin Whorf proposed a hypothesis claiming that a person's native language will control their thoughts and that if a concept is not expressed in one's native language, they will not understand this concept.
