just finished Ride of the Second Horseman, by Robert O'Connell
(about the birth and death of war)

specifically how war began with the split between agriculturalists and pastoralists (who began to raid agricultural settlements apprx 4000 bc)
which led to building walls around cities and later developed into warfare between agricultural states.. and how war served a kind of function that may be becoming irelevant in the modern world..

last nights fun.. which Ive just started and am enjoying.

also reading the Collapse of Globalism by John Ralston Saul.
