“I don’t read any more. I just talk to people who have.” – Dr Tom Malloy University of Utah quoted by Paul B Hartzog at Many2Many.
When two people have a conversation, they act as proxies for the many ideas in their heads which are drawn from the many things they have read. In effect, a conversation is a many-to-many interaction that is both mediated and moderated by the participants. The individuals catalog, sort, tag, and filter ideas as they are drawn into the shared space of the conversation.
So a conversation can be the little bridge across which the ideas inside us leap. Interesting perspective.
