It depends on how we define what we mean by the word "message". In the common sense interpretation "file" is not a "message". Nor is the display on which you are reading the message. Nor is a clay-tablet on which ancient Sumerians wrote messages. "Message" is information sent by someone to someone else. A message could be saved in a file but then the file is just the "medium" for transferring the message to its future readers. So I would think that "This message does not exist" is something like writing "This is not a pipe" on a painting of a pipe. I never understood what Marshall McLuhan meant with "Medium is the message". Medium is what makes it possible to transmit messages. Can anybody help me out, what did McLuhan mean?
