Sounds like Postmodernism to me. If you think it's not, then let me point out that you can just substitute "text" for "map" and you're pretty much there.
There must be something underlying the maps, because so many of those maps have turned out to be wildly wrong, completely barking up the wrong tree. It's not even that they didn't answer the questions correctly -- they were so wrong, they were asking nonsense questions in the first place.
There is a nice little allegory by Raymond Smullyan, where some ancient philosophers are debating what keeps the world from "falling down." I think it's in "5000 BC," and is the story by that name.
If there are only maps, then when map A is wrong, I can just make my own map B for which map A is a good map. In that case, no map is falsifiable, and all maps are equally valid. It's Postmodernism!
