@JLNobody,
...yes reality cannot be computed by a smaller part in it...agreed !
...thus we need a different definition of truth, an abstract one ! A final state of affairs that I cannot describe but that defines "me" and "my experience" in relativistic terms...
...if I cannot tell what is the case to be true as final, I still can although have a true partial and valid description of what "I" am experiencing to be "real", a relativistic local effect fully justified in "me"...
...on reality itself it can only be said that reality it is real as a whole a tautology which is not informative beyond the sense of necessary unity...
