I disagreed with his premise that we are becoming less aggressive
I don't think this is what he was trying to convey. Let me break it down and see if I got it right.
According to Oni...
(1) The natural tendency for a sociaty is to trie to progress
(2) Progres leeds two better living conditions
(3) Better living conditions lead to better social value for human lyfe
(4) Better social value for human life leads to less quarrels
(5) Less corals lead to less agresion
I don't think he's saying people over all are getting less aggressive. I think he's saying natural selection favors societies that are more prosperous because of the reasons I outlined above.
