This would mean that there is no common ground of understanding unless you share the same function. Pardon my Swahili, but, Bullshit
. Each function has its unique role, that has utility in our world, so each can have value beyond itself. And recognized as such...even by foreigners. For foreigners, it may take a bit more time than the natives, but, recognition can and do happen. And, a goat is not recognized as a dog, suddenly, but, still...a goat (even if they are not too familiar, initially, with what a goat really is). All about willingness to understand.
