In other words, you have no idea of how to express you concept in the terms of how a logic would be built with it, as you just don't undertand how logic works.

That every expression of language that is {true on the basis of
its meaning expressed using language} must have a connection by
truth preserving operations to its {meaning expressed using language}
is a tautology. The accurate model of the actual world is expressed
using formal language and formalized natural language.

You just don't understand what you are talking about, and think Formal Logic is just like the abstract philosophy you seemed to have studied a bit of.
Formal logic is a subset of this.
Not-a-logic-sentence(PA,g) ≡ (~True(PA,g) ∧ ~True(PA,~g))
There are no truth preserving operations in PA to g or to ~g
https://liarparadox.org/Tarski_275_276.pdfWithin my analytical framework this Tarski sentence is merely
self-contradictory
(3) x ∉ Provable if and only if x ∈ True. // (1) and (2) combined
There are no truth preserving operations in Tarski's
theory to x if and only if There are truth preserving
operations in Tarski's theory to x
