Sapir-Whorf hypothesis
"The early 20th century idea of Edward Sapir and Benjamin Whorf that language predetermines what we see in the world around us. In other words, language acts like a polarizing lens on a camera in filtering reality--we see the real world only in the terms and categories of our language. This hypothesis was objectively tested by anthropologists in the 1960's. That research indicated that Sapir and Whorf went too far. It is now clear that the terminology used by a culture primarily reflects that culture's interests and concerns. All normal humans share similar sense perceptions due to the fact that their sense organs are essentially the same. Therefore, they can understand and perceive the categories of reality of another culture, if they are explained". http://anthro.palomar.edu/tutorials/cglossary.htm
