Robert Anton Wilson, AKA R.A.W. explains how important language is in forming our belief systems and perspectives of reality. He discusses a method of communication called "E-Prime" in which the speaker refrains from using the word "is", forcing the author to describe reality in a relative and subjective manner. Freeing your mind begins with your perception of reality. Your perception of reality depends on your thought patters. Your thought patterns depend on the language you use to communicate with.
