Do you mean there were no institutionalized (even if unwritten) rules of social interaction in pre-historic societies? Fercrissake, Miles, your view of humanity is wrose than that of animals? Ever heard of the pecking order?
A related point - I think that jks' interpretation of my argument as that I supposedly see human nature as "independent variable" (by which I presume jks meant a factor that has an autonomous existence) is a bit harsh. I am pretty much against individualism, I believe that the individual is a creation of social conditions. What I meant by "natural state" was simply a heuristic device to denote human interaction without institutionalized rules of behavior - which can easily escalete into war of all against all. But it is, of course, possible that institutional rules of behavior may encourage violence against certain individuals.
