Is this a musing on Universality? wikipedia.org/wiki/Universality_(philosophy)
It's fascinating how some of the greatest thinkers have been wrestling with these ideas since the Greek times and here we are still talking about them. I'm sure we'll still be no surer in another few hundred years. ¯\_(ツ)_/¯
Universality is part of it, yes. Universality, materialism, pragmatism, idealism, they all are relevant here. For what it's worth, I am a materialist in a pretty strict sense.
