Two very interesting articles written by Rory Miller on real world violence, social and asocial violence. Social violence is what, in the natural world, would be the types of violence common within a single species. This intra-species violence does not follow the dynamic or use the same tactics as violence against other species.
The dominance game of snakes wrestling or bears pushing and mouthing is not the same as the way the same species hunt prey. Social violence includes ritualized jockeying for territory or status. It also includes acts to prove or increase group solidarity (a powerful side-effect of hunting as a team) and violence to enforce the rules and mores of the group.
Asocial violence does not target the victim as a person, but as a resource. Asocial violence is the domain of the predator and the humanity of his victim does not enter into the equation.
The following two articles explore these concepts in detail, particularly social violence and the ritual’s humans have adopted over thousands of years.
