The question (in non-physics terms) is IMO a series of oxymorons:
"Objective" anything (unless we imply unknow(n)/able features) is restricted to whatever the mind has interpreted upon impact(?) it received. Eo ips 'objective' is 'subjective'. "Reality" ditto, what WE accept as 'reality' - so objective reality is indeed callable some
subjective virtuality. "Defined" however is pure mind-work, the epitome of subjective, virtual activity. It seems GL concentrates on the "observable world" (>>White Rabbits to be filtered out of the observable world<<) which brings the discussion down to Earth.
"Frame of reference" is IMO mindset, with all its fundaments.
Seems strongly relatable with '1st person' (GL).

The 'formality' (in human identification) is subject to inadequacies
(like >Human systems are full of inconsistencies, errors, etc... <)
all as identified by the human mind. I doubt whether this is the only (logical?) system applicable? in which case our 'errors' may be OK in another view. Maybe more and for us controversial ones are OKable in some other system (beyond human capabilities).
I don't feel like discussing the dilemma (1 and 2) exposed by GL.

Subject: First Person Frame of Reference

Bruno,

I reread your post of  5/11/2004 and it raised some questions and a possible paradox involving the idea that the "notion of first person is absolutely not formalizable." (see below, for a quotation from your post)

The adoption of the first person as a "frame of reference" (my terminology) implies the ultimate relativization. In other words, the logical system governing the mental processes of the observer becomes part of the "frame of reference> However, we all know that human beings do not think according to formal systems. Human systems are full of inconsistencies, errors, etc... and very often their beliefs about the world is just wrong. Very often they even make arithmetic errors such as 8x7 = 65.

So if we assume a relative formulation, here is the dilemma:
1) if we adopt a formal system such as the one(s) your have talked about we assign an absolute quality to the observer which violates our premise of relative formulation.
2) If we adopt a non-formal human logical system," we are left with an extremely complicated task of reconciling the observations obtained by several observers who in my terminology "share the same frame of reference"

One of the question that arise is how fundamental should be the concept of "frame of reference" or of the mechanism/logic that underlies our thinking:
1) Is it governed at the atomic level by physical laws down to resolution of Planck's constant? The notion of observer is defined here with a Planck resolution.  If we share the same physical laws then we can say that we share the same frame of reference. This option avoids the inconsistencies of the "human logical systems" but throws out of the window the relativistic formulation. In addition this approach provides a neat justification for the equivalence of the sets describing the physical world and the mental world.
2) Is it governed at the neurological or even at the psychological level? The notion of observer here has a very coarse resolution compared to the first option. This approach keeps the relative formulation but becomes a quagmire because of its lack of formalism. How can the notion of "objective reality" be defined? In fact, is there such a thing as a true psychological objective reality?  However, the fact that a "psychological objective reality" is an oxymoron (contradiction in terms) does not invalidate the definition of the observer at the psychological level. Au contraire.
