Language maps the World in it’s own image. It draws the boundaries, shades the colors. And it is a self-sufficient mapped World that is very good at explaining itself to itself.
‘The World outside makes no sense. But come into my parlor and I will serve you a fresh helping of Words that will make everything nice and cozy’.
The language you ‘think-in’ is the unexamined repository of a millennia of influences. What ideas and things did the culture see as worth labeling? What distinctions did the culture see as worth marking?
Eskimos famously have a dozen names for Snow and the modern Investment-Banker a dozen names for Money.
Language creates the convention of legitimate distinctions that allow discourse. It draws the lines in the socio-linguistic matrix.
Reality carved in familiar ways is ceaselessly reinforced. A self-created line, repeated, entrenched, is now seen as a self-evident divide. Distinction, as Difference.
