Is chatter simply a output of our creativity that has been negatively used due to our propensity to want to survive? I think chatter is a a manifestation of of an otherwise healthy process that is going in the wrong direction. When i use the term inner voice, what i'm talking about is our ability to silently use language to reflect on our lives. And this is an amazing tool of the human mind. It's a tool that evolution has endowed us with that we are much better off as a species for having.
