As philosophy is the basis for all science (through the philosophy of science) and as it seems to implicitly denote the devices* of religion and any other abstract and concrete things (this and that), this seems to be the appropriate place to ask this question.
Forgive me if it is not.
*devices - in multiple but mostly the rethorical sense.
Assuming you are you and I am me and we are us and assuming that this works inter-species and inter-race/language and we can decide to either be-aware-of or ignore each other. Ignoring the fact that we can ignore each other for brevity:
it seems to make sense be able to understand (make sense to) each other as-soon-as-possible (more efficient/ASAP) any- and every- time (always), unless you're playing a game or telling a story in which there is a controlled timeline for the sensemaking process.
Now as these characters arose from Egyptian hieroglyphs through the Phoenician alphabet, Greek alphabet and Latin/Roman alphabet there were also people making sense using Written Chinese, the Arabic alphabet, the Hebrew alphabet or any other communication system available.
There are caves (-50000 years), walls (-10000 years), tablets (-5000 years), scrolls (-2500 years), to the use of paper (-2500 years to now), and decentralized communication ranging from telegraphy to the printing press and the emergence of mass media culminating in the internet.
If I'd read this in my cave 50000 years ago, I'd try to get my story straight and denote what's required for other to understand what I'm trying to say. But I'd like to also be able to ignore what someone's trying to say because I might be working on a different story. After 50000 years there will still be the choice to define something else as an interpretation of this story.
Now my question(s): does peace (read: harmony) require a shared unambiguous language (mathematical or musical assuming Latin/Chinese won't reconcile anytime soon other than over sound) and can it thus not be reached beforehand? And would it make sense to be able to "get people* into a frame of reference" ASAP to convey this sense of harmony or at least the sense of "making sense" or "ignoring"?
*people - any people should be able to identify with the story device.
