Dear Doug,

 

You wrote:

If you could boil down the claims of this early Libertarian and critic of

the New Deal into a formal set of assertions stated in a logical language

that would be a good foundation for a Libertarian "micro-theory" ontology.

 

The set of relations and types used by such assertions would be useful in a more general economics ontology.

 

RGC:> That is an interesting idea!  Do you have any suggestions as to what relations and types you think would be useful there?  Just having a vocabulary of such logical constructs might help use explore the issue in more depth.  Most of the discussion so far quickly descends into muddy personal issues instead of staying with the economics of the debate.  If you could clarify the real issues in some way, that would be very, very useful. 

 

Does Henry Hazlitt's book explain why it is in the self-interest of the

Republicans to do what is necessary to ensure that the US economy does not improve before the November 2012 election so that they have a better chance of gaining control of the Senate and presidency?

 

RGC:> No, it doesn’t, but it SHOULD delve into how self interest (such as you describe above) leads individuals and groups to practice destructive policies (like seeking to limit the economy) for purely selfish purposes (like Republican hegemony in the 2012 elections). 

 

The best we have so far is game theory to explain the behavior of small groups of individuals – not much more than two.  Perhaps your relations and types suggestion would be useful in explaining a lot of self interest actions.  If you feel inclined to propose any that could be very useful. 

 

Thanks,

-Rich

 

Sincerely,

Rich Cooper
