Someone who is philosophically literate in technical forum: a rare treat! Nice!!
Wittgenstein is a favorite of mine and I often reserve one lecture for his:
?Limits of my language are the limits of my world?
Then amplified by Roman Jacobson?s ?Languages differ not in what we can say
but what we must say?
And finally with Whorf's evidence that words can set buildings on fire
[Today it would be send countries to war]
However Wittgenstein's quote above on identity is too terse to properly grasp
the real difficulty
shows at some (verbose!) length that identity is and can only be a hopelessly
circular definition. A problem which has little to do with python, programming
languages, or CS in general; it is a fundamental universal problem
