And that's a lovely quote, but what does that have to do with war between groups. This might have relevance if I were discussing some sort or societal revolution, but where chimps are concerned, "revolution" is the changing of a dominant alpha, not a true societal structure change (and, yes, the same can be argued that differing forms of human government are illusory as they end up degrading to an alpha male style group, but that's a discussion for a different day). War, in most cases, involves violent conflict between disparate social groups. Maybe my comment was mistaken due to the breakdown of English in pointing to different types of conflict, where "war" has become a general phrase for conflict..... otherwise, I don't understand what this imaginary, egalitarian society phrase has to do with war. The real truth of the matter is, when food, sex and space are plenty, conflict is sparse. When any of those become scarce, conflict will happen and might will make right.
