Dear Stephen,

I try to clarify my position.

*>From the conlusion, I agree that gravitaion will be given a QM formalism, but
*

it will be at the last step of my approach.

What I am trying to understand is the machinery or structure of our

recognition with the expectation that it will clarify physical aspect of

gravity. In this point, I think your approach has the same goal, or you will

get to it at least as some byproducts. However, I think it necessary to

understand the fundamental structure of observation first.

I feel you seem to try to get at once the QM theory of gravity, seeing that

you are interested in Weyl's approach. On the other hand, seeing that you seem

to think that interactions as communications are important, Weyl's approach

looks to me slightly different from what you want to understand in terms of

information theoretic approach. I do not see what approach you try to take

toward QG.

Best wishes,

Hitoshi

*

*> Yes, Peter and I discussed this for a while. It appears that the
*

*> subject-object relation is symmetrical. There is a wonderful thing that
*

*> happens when we consider an LS as a subject as a singleton set A and the
*

*> other LSs that it is near to as the singleton's complement A^c. If we
*

*> think of A^c as a finite number of LSs that can somehow be reduced to a
*

*> singleton by some particular observation by A, by symmetry, would we not
*

*> expect that A becomes many neighboring yet distinct LSs? As one fuses,
*

*> the other fissions, many -> one | one-> many ... Does this make sense?
*
