The pursuit of knowledge is painful. When we learn something new, a language, a scientific theory, an ancient philosophy, we not only get to know what they are, but also what made them.
This is especially true in Language.
"After you learn a language -if you care enough- part of you becomes a member of the tribe to which the language belongs. And that cultural schizophrenia can be truly excruciating."
The key part being if you care enough. If you care enough, you will discover their lifestyle, literature, and past of their society. You'll think in that language, about them.
The knowledge of the language and the nescience of it's culture inevitably leads us to think more about them, and how they think and how your life there would've been.
I have been surprised on occasions when people are not at all affected by thinking about these things. They genuinely don't feel anything or any sort of invisible connection or that inexplainable feeling of being somewhere else or being somebody else. I still am. Or people just don't talk about it😐. Yeah, that makes more sense.
Hope we'll be able to name and translate that feeling.
