«Thus, it could not be claimed that some societies are inherently or genetically peaceful, while others are inherently warlike. Instead, it appears that societies do or don’t resort to war, depending on whether it might be profitable to them to initiate war and/or necessary for them to defend themselves against wars initiated by others. (…) It is equally fruitless to debate whether humans are intrinsically violent or else intrinsically cooperative. All human societies practice both violence and cooperation; which trait appears to predominate depends on the circumstances.»
