Yet, one way of seeing, one way of thinking, one way of knowing, one way of doing, one way of living -- one paradigm -- is being imposed upon everyone in the world
I kinda agree with the gist of that, while I disagree with the wording. Seeing, knowing, doing are well defined singular things, there is only one. "Way of living" is the only one that works to make the point.
But yeah, one paradigm imposed on the world isn't going to work - nor is it going to happen naturally. "Maturation" implies some type of improvement, but that's not in any way guaranteed by nature, partly because of way we renew. Every year there's a new set of "default humans" created, without knowledge of the thinkers you quote, nor your life experience. Even if you were correct about absolutely everything, you wouldn't be able to convince them that you are. Even if you get everything to be "fine for everyone" for a generation, the next one will figure out new ways to improve their individual lives at the cost of others. The only natural thing here is change; not maturation.
Thinkers have this habit of confusing people with thinkers. "I came to this obvious conclusion, it's only a matter of time everyone else does too." That works exactly until you get punched in the face by the guy who doesn't care for your ideals, just wants your wallet. That guy doesn't want to be part of the maturation, so he isn't. And if one respects freedom, there isn't much one can do to change it.
As a species, I think we're best off in somewhat isolated groups. Separate populations producing their own unique strengths - or at least avoiding the mistakes of others. The less single points of failure in the system, the better. The global powers that want either maximum profits from trade, or to save the planet from "those humans"; well, they'll have to employ force globally to reach their dubious goals. This is why I get queasy with ideological optimism; it won't work without force, and some of the adherents are going to be willing to try with it.
