We're probably post-narrative and post-lexical (words) but haven't become aware of what to possibly update these tools with. Post-truth is an abstraction rooted in the arbitrary.

Reality is specific. Actions, materials. Words and language are arbitrary, they're processes, and they're simulations. They don't reference things, they represent them in metaphors, so sure they have "meaning" but the meanings reduce the specifics in reality which have many times the meaning possibility to linearity, cause and effect. That's not conforming to the reality that exists, that's severely reducing, even dumbing down reality.
