I am happy you see that COMP implies Indeterminacy + MW.

But the entire UDA TE shows that the mind-body problem is

reduced to extracting the physical laws for the measure

on that indeterminacy. This explain at least the philosophical

shape of QM. And it shows that COMP entails SE is SE is correct.

And Church thesis entails constraints which made that measure

isolation possible. (Even by pure self-observation or by interviewing

the self-observing universal machine).

And here we get a sort of double quantum logic which I should

explain more (but then we need mathematical logic).

I also use the COMP hypothesis which help by giving both TEs, and

precise mathematical theories. It is frequent that focusing on point

and focusing on links are related by dualities. With the Z logics the

links are really topological. I think I have shown a way to derive

the thickness from the turing-tropic views.

You just need some knowledge in mathematical logics. I will think for

a good book. (Godel speed-up paper is in the Davis 65).

OK...

*>The point is that
*

*

The observer defines the worlds in which they live. The expression "an

observer is or belongs in a universe" is not well defined with comp.

if the false memory has a bad influence relatively to a non negligeable

set of consistent continuation for an observer, then and only then that

"false memory" has a (relative) meaning and *is* indeed relatively

false.

*

*>The

*

But they are relatively real and why not consider them

important too especially when one want understand the

laws of physics from them.

The set of consistent extensions is perhaps fuzzy, but they are

mathematically well defined (with some assumptions).

Turing-tropic instead. That the simple shift I do. There is a nice

mathematical way to interview the self introspecting honest machine.

(BTW and by Solovay there are *two* nice utterly non trivial ways).

I don't understand. The guys after the self-duplication in W M share their

life stories until the duplication. I talk of sharing because of

bifurcation,

and merging.

*>Can conventional mechanics support consciousness spliting and merging? I

That would just mean conventional mechanics is incompatible with comp.

That is quite possible. QM *is* compatible with comp, perhaps even

a consequence.

This is exactly what happen with comp. Consciousness is represented by

the set of all consistent extensions. That gives, it seems, the right

"fuzzy region".

Why mandatory? Not planck constant but the existence of planck

constant is related with the fact that comp entails that if we look

below our level of substitution we can get information from the

proximate "parallel" computational histories.

PS I get the following "Re: Transporter Paradox". It seems

at first sight you just

affirm comp is false there.

for exemple you wrote:

*>If the transporter was perfect, then, obviously, the copies would have
*

*>to be
*

*>perfect. This means they would have to include all their extensions which
*

*>includes
*

*>clothing, close environments and far environments. To be rigorous, let's
*

*>say that all
*

*>the environment withing a light cone of the observer is reproduced by the
*

*>transporter
*

*>such that no information can possibly be lost.
*

This just mean you put the level very low. But comp just say that

there is a level such that a perfect transporter exists in principle.

The UD will patiently

get it and simulate you (infinitely often) + all the infinitely

many variations ...

To make comp false there would be no level at all!

The rest of your post is incorrect. Either comp is right and then

the UD will emulate all correct "transporter" or comp is false and

then what I say does not follow ... so "easily" indeed!.

*>Bruno's assumption that indeterminacy can be deduced from
*

*>COMP is faulty.
*

You change your mind but I don't see why. I guess you belief

(momentarily I hope) that I pretend comp true. I never do that.

I just pretend that if comp is true *then* physics is eventually

a branch of machine's theology, biology, psychology (choose your word).

Once comp is true the DU duplicates exactly infinitely often

and with the invariance lemma your anticipation (including f=ma)

are determind by the topological structure of that set of

consistent continuations.
