The puzzle is why you don't grasp the fact that the writer is
obviously arguing against the idea of a single ontology.
At the cost of getting scolded, this discussion is far from exhausted.
To the contrary, the discussion from which you lifted the above is entirely exhausted. Azamat had claimed that a certain passage he found on the NeOn website was confusedly arguing both for and against the idea of a single, unified ontology. In my comment above, I was simply pointing out that he was wrong about that; the passage he had quoted was quite clearly arguing against the idea of a single, unified ontology. He had simply misread it. End of discussion. I expressed no opinion whatever on the substance of that issue.
