Financial paper: variations on themes of McLuhan.

This article refers to a comment made by Marshall McLuhan, which suggests that communication has become the things being communicated, the media control, and the men that manipulates it. The article uses this idea to explain how stock certificates and checks have taken on qualities apart from their meaning as signs of corporate ownership or monetary value. The article discusses the message as the medium, the extensions of man, how man can be controlled by the system and what can be done to prevent it.
