Good article and, as I see it, a barely-concealed challenge to actually come
up with an experiment that will prove or disprove MWI.  I’ve seen a few on
the Los Alamos site from time to time, but nothing that wraps it up.  And
Young’s experiment shouldn’t count.

I am pretty sure that there is a profound misinterpretation and/or
unrecognized presupposition deeply embedded in the kinds of discussion of
which Van F and your reply and Bruno's  fits.  It's so embedded that  there
appears to be no way that respondents can type words from a perspective in
which the offered view may be wrong or a sidebar in a bigger but
unrecognised picture. It's very hard to write anything to combat view X when
the only words which ever get written are those presuming X, and X is
assuming a position of explaining everything, yet doesn't.

In the long run I predict that:

1) The 'many worlds' do not exist and are a product of presuppositions about
scientific description not yet understood by the proponents of MWI.
2) QM will be recognized as merely an appearance of the world, not the world
as it is.
3) The universe that exists now is.the only universe that exists at the
moment. Despite this, the "many worlds" are explorable, physically by
'virtual matter' behaving as if they existed (by an appropriate entity  made
of the stuff of our single universe)
4) The MWI has arisen as a result of a human need to make certain
mathematics right, not the need to explain the natural world. This, in the
longer term will be recognised as a form of religiosity which will be seen
to imbue the physicists of this era, who are preselected by the education
system for prowess in manupulating symbols. The difference between this
behaviour and explaining the natural world is not understood by the
physicists/mathematicians of this era.
(In contrast, I regard myself as a scientist  an explainer of
things-natural ...which I claim as different to being a
physicists/mathematician in this strange era we inhabit)
5) COMP is false a computer instantiation of rules of how a world
appears to be, and a world are not the same thing.
6) COMP is false a computer instantiation of rules of how a brain
appears to be is not a brain.
7) Corollary: scientific description of how the world appears and what the
world is made of are not the same description _and_ computer instantiations
of either set is not a world.
8) The issue that causes scientific descriptions (like QM) to be confused
with actual reality is a cultural problem in science, not a technical
problem with what science has/has not discovered.
9) That most of the readers of this list will stare at this list of
statements and be as mystified about how I can possibly think they are right
as I am about those readers' view that they can't be right.

BTW I have a paper coming out in Jan 2011 in 'Journal of Machine
Consciousness' in which I think I may have proved COMP false as a 'law of
nature' ... here in this universe, (or any _actual_ universe, really). At
the least I think the argument is very closeand I have provided the
toolkit for its final demise, which someone else might use to clinch the
deal.

This leads to my final observation:

10) I think the realization of the difference between 'wild-type'
computation (actual  natural entities interacting) and 'artificial
computation' (a computer made of the actual entities interacting, waving its
components around in accordance with rules /symbols defined by a third
party) will become mainstream in the long run. 
-
It's quite possible that the COMP of the Bruno kind is actually right , but
presented into the wrong epistemic domain and not understood as such. Time
will tell. The way the Bruno-style' COMP can be right is for it to make
testable predictions of the outward appearance of the mechanism for delivery
of phenomenal consciousness in brain material 

NC (natural computation) and AC (artificial computation) is the crucial
distinction. I don't think the QM/MWI proponent can conceive of that
distinction. Perhaps it might be helpful if those readers try and conceive
of such a situation, just as an exercise..

You are presuming a lot about physicists.  The idea that QM, and more 
generally mathematics, is just description and a representation of one's 
knowledge, not reality, is very common among physicists.

I can conceive of it as relative.  If there is a world N which is very 
large and complex compared to a part, A, of that world and the 
computation in A is used to represent something in N, then I can see 
regarding A as artificial relative to the "real" N.  But that's not an 
absolute distinction, since N could be a simulation embedded in a still 
larger computation.


I could also conceive of it as analog vs digital.  It might be that the 
real world can only be described by real or complex numbers and digital 
computations can't completely simulate it - but this seems both very 
doubtful and probably impossible to test.


So how do conceive the distinction?

Thanks for the van Fraassen paper. I have already argue that the  
"modal interpretation" of QM is a form of MWI, and that paper confirms  
my feeling. Not sure it is really new if you read with some attention  
the entire thesis by Everett.




First of all we need to admit that if we are to be consistent  
with the mathematical prescriptions of quantum mechanics, each and  
every one of those scientists and table lamps, as physical objects,  
have a wave function of sorts associated with them and, assuming  
that they could interact, are entangled with each other. “Being in  
the universe” implies to me that that there is a sharing of context  
and maybe even a common basis of sorts. But is that all there is to  
it? Hardly! being a table lamp, when considered from the quantum  
perspective is not so simple. We cannot assume that there is any  
definiteness of properties in a sharp sense. When we consider a  
Table Lamp or any other physical object in isolation at best we have  
a superposition of possible properties, and what is the outcome of  
measurement is given in terms of restrictions upon those  
possibilities by the possible properties and modes of possible  
interaction of all of the tables, chairs, beds, etc. that are in the  
room with that table lamp and beyond. We cannot assume that what  
something ‘is’ is somehow invariant with respect to changes in the  
interactions that it has with all of the other objects. This is a  
very subtle point that need to be carefully considered.
   The notion of a Table lamp in isolation literally dissolves into  
nothing when we remove all those other objects upon which its  
definiteness of state persists. The conflation that has persistent  
for more than 2000 years is the idea that object in themselves are  
what they are. I am reminded of Einstein’s quit to Bohr that the  
moon would still exists if he was not looking at it. My response to  
Einstein is that he is not the only one interacting with the moon.  
We need to take the whole web of interactions into account when we  
consider the definiteness of properties otherwise we are only  
considering bare existence and that tell us nothing at all about  
properties.





It should be obvious, if you get the UDA, that physical reality does  
not have a "view of nowhere" or an ultimate third person describable  
reality. Mechanism makes the physical reality a first person plural  
reality, with the person played by the Löbian machine or Löbian  
number. There is still a boolean ultimate third person view available:  
arithmetic (or combinators, lamda calculus, etc.).


And this contradicts nothing written by Pratt, who is indeed a little  
less naïve than those defending the identity thesis. But Pratt  
scratches only the surface of the mind-body problem: he identifies the  
physical with the set-theoretical (which is not so much senseless  
actually, but far from leading to extracting QM from numbers), nor  
does he tackle any problem in the cognitive science (qualia,  
undefinability, rôle of consciousness, etc.). But his SET/SET^op  
duality is rather natural for a category theory minded attempt to go  
toward a formulation of the mind-body problem. His duality is also  
100% mathematical a priori, which makes him mathematicalist like  
Tegmark, and like comp (with some nuances).


In november I will have a bit more time, and I could add something on  
both van Fraassen-Rovelli and Pratt.


Best,

Bruno
