Personally, I'm not sure there IS a "natural" society. Or at the least, not one that has been discovered as of yet. On the other hand, the opposite could be the case, and all societies are "natural", at least in the sense that they were dreamed up by humans (so far as we know, that is).
Who knows? It may be that I was "indoctrinated" during my formative years, leading me to this generalized dislike for communism and socialism, despite socialism's (or a form of it) current existence in US society.
If that were the case, then my dislike is “unnatural”.
And really, the training/indoctrination/etc. that takes place in the more formative years could be considered as part of “human nature”.
Personally, I don’t think there is a “human nature” as such… Or rather, human nature varies widely depending on the events during those “formative years”.
Still, you probably would agree that if you tried to implement a completely communistic society here in the USA tomorrow, many people would disagree, some violently, making it nearly impossible to emplace (unless US citizens are far more apathetic than I fear) without enforcement methods.
Whether this stems from a “human nature” produced by ingrained and institutionalized indoctrinations against communism/socialism or some unfathomed “human nature” that is intrinsic to all humans, cannot really be determined, since any test I can think of would violate many of the moral codes that are…ingrained and institutionalized into our collective psyche.
Nonetheless, it indicates that “human nature”, such as it exists here in the US of A, would resist an overall communist governing method – or however you want to describe it.
IMO, it cannot be determined one way or the other whether any given societal system is “natural” or “unnatural”, seeing as the very system you are examining would either be that which you currently reside in, or one similar, counter to it, or both, in several ways.
So, I would say all systems are “natural”...and at the same time, none are.
Damn, I really typed a lot there…
