These three files represent three slightly different file formats of the text,
in .ppt (or "Power-Point") format, for my lecture as presented in Lindau in August 
2011 and in Beijing a little later.
    The specifications, for the meetings were for shorter lectures, like for 30
or 40 minutes. So my text is rather short. But with the process of reading it out
and being prepared for questions I was fittingly prepared for the context of these
meetings.
    Also, diplomatically, I wanted to avoid getting into the direct criticism 
of "Keynesians", which is an area with political complexities and subtleties which 
complicate circumstances where, otherwise, a student might have a simpler perspective 
on the facts of things affecting the use of money in human civilization.
