I was giving your article some more thought. I think what’s interesting about your explanation of violence is that, as a society develops alongside another, one or the other slowly realizes that their self-interests align with treating the other more fairly; that because a society’s goal is to, in some sense, flourish, it would therefore be rational to consider and act on the other society’s interests. So there’s this kind of rational development that a society participates in as it grows and becomes more productive. It’s worth wondering about whether that development is a moral one or not; whether a society that undergoes this process is also developing a collective moral conscience, or if it’s simply reducible to some biological process. Just a thought.
