Colonel John Boyd and the ancient tripartite structure

Another way to look at the value of Colonel John Boyd's ideas on the different levels of war is to see them corresponding to the hypothesis of the ancient, tripartite, Proto-Indo-European (PIE), class structure: Boyd's physical, weakest level (PIE commoners, economic), the mental, middle level (PIE military, strategy, ) and the moral level of war, the most powerful (PIE the sacral, priests). Boyd's ideas on military strategy seem to have hooked into (probably unconsciously) a very old system, one that eventually conquered the ancient world.
