It seems as if language as a tool is hindered by the existence of parts such as pun, surreal connection or tangent. If I were to say "Hi, look yonder! Thar she blows, a ship" it could be inferred that I meant "hello, listen to me east-ender, there's a hooker over there or maybe you want a shipment of narcotics" - in fact that's just one of infinite inferences one could make.
If we are to use language in order to expand our knowledge in a categorical sense then I suppose that one needs many more words in order to describe the different categories which we encounter.
Of course this is impossible, we could not have a word for every atom (supposing that every part of matter is unique), nor could we countenance a name for everything we know (for example each equation in maths having a name unrelated to it's inventor, ie a 'word' not a 'name').
Having studied some Buddhist script and a summary of Judeo-Christian/Islamic relations in the past month or so, I'd say that philosophy is dumbfounded in the presence of groundbreaking (personal or "for all persons as a whole"*) proof of knowledge; our language cannot explain for example the differences between social interaction and "flirting", sometimes an occurances drifts between boundaries and categorizations.
I suppose that "tota-personal" could be a word to describe such a thing.
Getting back to the point, there are some who say that an individual is simply 7 steps through societal interaction to any person on earth, so why could knowledge and the melange of language not develop the same? A simple point, I know it seems rash and unprovable.
If we regard language is a fundamental provision for knowledge then surely it is the language at fault for such discrepencies in the possible relativity of categories.
I do not believe that a new language must be founded, but that languages be developed in order for the individual to express deep emotions - that is a start, and one which would be greatly beneficial - instead of messing around making words that fit into common linguistic usage, why not make new words that present possiblity for the expression of said individual?
