scule: That’s a good point about slaves. They really were thought of as property. As to the value of communication, well, I won’t write it off completely, but I recall that there have been very vicious civil wars and other conflicts between people who share a language and a culture. Humans can divide themselves into small, petty factions rather easily, and such divisions can become the basis for protracted feuds. For starters, you can look at the Chinese civil war (1911-1948), the Irish Troubles, and, to a lesser extent, the Israeli-Palestinian War.
Philosophy, too, can be subverted and used to prolong, instead of shorten, conflicts. Communism as idealized by Karl Marx, that Golden Road to Utopian Socialism, has never been implemented fully but the people in charge have ruined the country they ruled. There is no chapter or verse of Marx that advocates the subjugation of the masses under the steel boot of governmental oppression, but that is what always ends up happening.
I like how your philosophies would point, the idea that a rational and well-connected world would of necessity be less cruel, but I simply cannot see the world as being quite so amenable to my wishes.
jsgoddess: Even more good ideas! Your theory, if I understand it, essentially posits a fundamentally lazy nature to mankind, and I think we can all agree with that. Why bash my neighbor’s brains in when I have 250 channels and unlimited Internet time per month? As a programmer, I view a certain kind of laziness as a virtue (look up some of the writings of Larry Wall on the subject), and this idea fits right in with my observations of myself and others.
(That could be seen as bias. So be it. I am a somewhat pessimistic person, and I don’t see humans as being excessively noble or philosophic. Since I see even less virtue in governments, I suppose laziness can serve as a natural cap on the brutality of the majority.)
