I am interested in the feats of Humanity (with capital H) , not in how it is realised in Lingala, Mayan, or Cheso. This interest I leave for philologists, which I am not. With your permission, of course.
This borders on a strange problem that some linguists have: you're interested in the big picture but not data. As long as you do use reasonable data (and not all from English, please!) I guess that's ok. I'm interested in the big picture too. But I am looking at diverse languages to do that (recently at Mayan and Lingala actually, not Cheso though).
Put another way, Gui is interested in society, but not the individual — and if there is one thing us Nordic socialist commie bastards have learned, it's that you cannot separate individual and society; they are two aspects of one and the same thing, and any line between them is incredibly thin.
You need both the puzzle pieces and the picture puzzle. Looking at only the picture you won't be able to finish the puzzle because you don't know what the pieces look like; looking at only the pieces you won't be able to finish the puzzle because you don't know what the picture looks like.
In a way you could say that it dehumanises humanity :/
