Solving the "elf superiority problem"

[Max_Killjoy]

How would you make a setting where people can put truly all the needed ideas about a subject under the form of a text?
How do you make a language that does not suffers from the fundamental imperfections of language?
It would make a setting much more alien relatively to reality.

You're treating the "limits of language" as asserted in one theory of language, and the minutia of one theory of how the mind supposedly works, as some sort of given and immutable laws of physical reality... latching on... and then blowing both all out of proportion to attack a rather straightforward and simple distinction between ideas that are new (to the individual) and ideas that are copied from outside sources that's being made for the purpose of an RPG setting.
