ABSTRACT
The concept of information is central to understanding human communication.We value a letter from a friend because it informs us about something that interests to us. In communication, we inform each other about each other and create worlds of coordinated concerns. The significance of information does not derive from the matter and energy that is inevitably involved in any exchange of messages, but from the interpretations it affords. Information is what we do with the messages we receive, not what they contain.
