Switzerland has 4 official languages....gee, why would that be? Perhaps because: 1) they have different VALUES for their country. That they value placing 4 languages on par with each other makes them automatically DIFFERENT from America just in that respect. And BECAUSE they value different languages, their culture has EVOLVED differently FROM America, which has historic cultural values of its citizens learning and speaking ONE language, called ENGLISH....and with learning ENGLISH, one learns the history of ENGLISH.
A common language serves to unite a people.
From the commonality of language comes the ability to communicate agreed upon OTHER values....most of which are found in some sort of document, which DEFINES what those values are (i.e., the Constitution of the United States of America).
Through these agreed-upon definitions unique to the particular country, comes a unique culture, which grows, over time, but still holds, through that growth, the "essence" of what makes that country a unique country and culture different from others.
The three are INTIMATELY connected.
