Explanation:

Benjamin Lee Whorf claimed that the structure of the language we speak determines our world view, thought and even our cognition. In oder words the way you interprete the world depends on the language you use to think.

This principle was first widely accepted in the begining of this the 20th century, but lost acceptance with Noam Chomsky's formulated arguments against it.
