“Language shapes the way we think,
and determines what we can think about.”
—Benjamin Lee Whorf (American Linguist noted for his hypotheses regarding the relation of language to thinking and cognition and for his studies of Hebrew and Hebrew ideas, 1897–1941)
“To have another language is to possess a second soul.”
(Quotes via Invisible College II.)
I honestly wish I would've stayed in French classes as a child, but back then no one wanted to learn French. (As an odd twist, our French teacher in elementary school taught us Christmas carols in Ukrainian one year.)
However, just as I've mentioned before, the mastery over one's monomyth as put forth by the likes of Joseph Campbell allows the mastery of two realms analogous to "languages," as put forth above. Rather than thinking of them as just languages, think of them as subcultural perspectives. Each particular vernacular hosts a different perception, and consequently a different approach to social interaction, problem-solving, and ways to be creative and entertaining. Language is a means to communicate, involving so many different methods.
The very poetry of one's life can change by adopting the languages of others.
