Does this differentiate between different groups of humans, i.e. that the perspectives of those humans who refect less accurately on the cosmos, are in some way inferior and less important?

You could go further. The truly privileged perspective is my own, as I have no idea what is observed by the other six billion people on this planet. This moves us on from a geo-centric view to an ego-centric view.

Of course, it seems unlikely that the Earth is the only place that life exists in the universe. Indeed it is rather difficult to exclude the possibility that there are many other locations in this universe where lifeforms "think and reflect accurately on the cosmos". A lot of them may even do it better than we do. By your reasoning we should be using the brightest and best of these as "foci". That we don't know where they are is no excuse for ignoring them. Either way it means that the geocentric perspective isn't that privileged in the grand scheme of things, and we perhaps shouldn't go looking for deep meaning based upon it.
