Ideas can only be interpreted using what we know, understand or perceive. This is because what is defined to be real and possible is sustained by beliefs and hypothesis. Our perception of our reality is only limited by what we believe about our experiences. Our ability to perceive, describe and communicate our experiences is equal to our knowledge and ability to use language. It is our knowledge of words that determines our ability to use language. Language determines both our ability to interpret an idea and our ability to effectively communicate it to others.
