The idea is to suppress traces of animal instincts from humans for the goodness of the society.
This isn't too far fetched, if one, for example compares an Italian from Sicily and a Japanese from Tokyo (two very extremes). They are, on average, two very different kind of people, yet humans capable of the same tasks. (though I can't say that Japanese are not emotive as they have their own outlets (usually at drinking time) and are a lot more open about crying).
Culture is certainly the principal reason for such different behaviors and approach to society building, but one has to wonder whether there are biological traits that influence all this.
For example, I was born and raised in Italy, but I never found it easy to fit in the Italian lifestyle. Now, I don't think Japanese society as is really suits me, it certainly works better than the Italian one. It's not uncommon to find a better home in a different country, though still fairly rare.
Of course, finding the right balance is the problem. Too mild mannered, too cold and creativity may drop, but when moods heat up, crime, drama and, ultimately, wars can come to place.
Overall, the current situation is not so bad. Geographical distances still work well as insulators: conflicts in middle east will just never end and I don't care as much, because I sit comfortably in Japan while some other very dramatic and scarred societies fight to the end.
Same goes for Italy, I live my life here and almost hope for Italy to reach the bottom. No wars there, but a very polarized society. Polarized by politics, soccer and racial tension more recently (for the past 10-15 years).
So, where exactly is the balance between free-riding animal instincts and total suppression of emotions ? I don't really know. But I think that it's currently safer to err on the mild side and live and act less like an angry reptilian on steroids.
I can only hope for everyone to commit their own mistakes as quickly as possible:
- Middle east is hopeless, I truly can't see a way out. They need hundreds of years.
- Political corruption and general broken democracy has some hope with the Internet (as long as Google doesn't start siding with classical media). USA starting to lead forward after touching the bottom with W. Bush and Diebold.
- Corruption, short sightedness, lack of altruism and racial tension, those are more difficult. Though close to politics, they can't just be enforced (leading to a police state instead), they have to come from everyone's basic understanding (indoctrination ? (^^;)).. as it's too much of a cultural issue.
Must keep those brain cells going !!
