It's a moot point. We could all be experiencing the same reality and having the "exact same experiences".commonsense wrote: ↑Wed Nov 20, 2019 6:20 pm Wittgenstein once implied, and later retracted, that reality is a projection of internal experience. I am willing to believe that everything extrinsic has an intrinsic basis.
I know that I am I, but I cannot know whether you are you. Because of this, I should not care what other so-called “persons” observe.
The bodies of knowledge and languages we develop to speak of those experiences diverge.
We end up developing different conceptual schemes - if our respective societies/tribes are isolated and don't interact with each other we WILL develop our own cultures, traditions, languages, dialects and rituals to the point where we are unable to communicate.
Even if our thoughts are structurally identical (something which we can't test), it makes no difference if what you call "blue" I call "藍色".
This problem is so endemic to human language that even scientists with different specialities have trouble exchanging ideas with each other.
Even couples that have been with each other for decades know that 99% of all disagreements boil down to miscommunication.
It's Wiio's law
And there's absolutely no problem with that - you know how you use your words. The trouble is communicating your use to me in the absence of a shared language/history.commonsense wrote: ↑Wed Nov 20, 2019 6:20 pm “I am [insert label here, wherein label points to an adequate collection of characteristics that apply to me]” is tautological, but it is a definition after all.
That requires on-going interaction so THAT a shared language/history can develop. Is why human relationships are such hard work - the world has practically set us up for failure.
