Who said: "There is no central arbiter of truth in open distributed systems." Can anyone give me a reference to the origin of the statement "There is no central arbiter of truth in open distributed systems."

Possibly it was Carl Hewitt in "The Challenge of Open Systems" Byte Magazine. April 1985. Can anyone confirm this?

Thanks
The exact quotation seems to be:


  "Pluralism: There is no central arbiter of truth in the system."
