OK. Thanks for saying. I will try to be charitable, so John Clark, if

This is a key element in our disagreement. I maintain that by itself a
consciousness has no way to directly tell the difference between the hear
and now and the there and then. For example if you were to build a
intelligent brain out of atoms and let it operate for one hour and then
destroyed it, and then wait for a billion years and then make another brain
identical to the first one out of different atoms and let in operate for
one hour interacting with identical environmental conditions, then I would
not say that 2 different things were conscious for one hour nor would I say
that one thing was conscious for 2 hours, I would say that one thing was
conscious for one hour. For this reason even if the eternal return style
immortality were proven to be true it would give me no comfort whatsoever.
To me this is obvious but many, probably most, think I'm wrong. I guess our
brains are wired differently.

  That expression is traditional, and used in many place,


You are unlikely to find the truth in this matter through tradition.

 I was just saying that consciousness of a localization does not entail
 the localization of consciousness.


In other words you can think about and receive sensory input from a
particular place. I agree.

  From my 3-view I can clearly see that the brain of Bruno Washington is
 different from the brain of Bruno Moscow, one has memories, that is to say
 physical changes in the brain, of the sights and sounds of Washington while
 the other has brain changes signifying the sights and sounds of Moscow;
 because of the changes in physical structure the two brains operate
 differently, or to say the same thing with different words, I the third
 party can see that the mind of Bruno Washington is different from the mind
 of Bruno Moscow.  Provided that Washington is different from Moscow (I've
 never been to Moscow but I imagine that it is) then the brain of Bruno
 Washington is physically different from the brain of Bruno Moscow, and I
 the third party observer can see those physical differences, and if the
 construction of those two objects are different then the way they operate,
 the mind, is different too.


  But this contradict the fact that you agree both person are the Helsinki
 guy.


How in the world is that a contradiction? You are the Bruno Marchal of 5
seconds ago, but if Everett is correct then in some parallel world 4
seconds ago Bruno Marchal turned around and was surprised to see a fully
grown Siberian Tiger in the room with him. Both you and Tiger Bruno are the
Bruno Marchal of 5 seconds ago, but you are not Tiger Bruno and Tiger Bruno
is not you. In fact although the time between the split is not long the two
of you are now very different, one had a traumatic experience and one did
not,  but both remember being Bruno Marchal of 5 seconds ago.

 I begin to believe, that John Clark only fake to not understand,


Bruno, if I thought you had a good idea why would I pretend you did not?
Looking for good ideas is the reason I'm on this list. I understand exactly
what you're saying, in fact I believe I understand what you're saying
better than you do.

And both those consciousness'es could access identical memories of the first 50min.  So if 
one remembers thinking, I hope to see Washington. the other will remember the same

significant?


The WM setup and the Universal waves are deterministic.




Everything predicts that. OK, then I have a marvelous new thought  
experiment, let X = Y. I maintain that comp predicts that X= Y and I  
have made a wonderful new discovery too.


   you should expect the WM duplication as equivalent with the  
throw of a random coin, etc. But you don't need to agree with that  
analysis. You need only to agree that there is an indeterminacy


  Of course there is a indeterminacy!

 Don't say of course. That is not so obvious as your posts  
illustrates.


it's not obvious that the outcome of a RANDOM coin flip is  
uncertain? I thought it was.


I was clearly talking about the duplication.





 In the 3-view there is no randomness at all. In the protocol, we  
don't change the pixels randomly, neither in the comp multiplication- 
movie experience, nor in the quantum wave which evolves  
deterministically. The point is that the randomness bears on the  
first person experiences. We get this directly with comp, without  
assuming QM.


Nothing new. People have only known about Quantum Mechanics for  
about a century but they've known about randomness for many  
thousands of years. And you've made randomness a measure of  
ignorance rather than a property of the thing itself and that's how  
it should be, and what people have always done. This is demonstrated  
by the Monty Hall problem, a new car is behind one door and a goat  
behind the other two, you pick a door at random and Monty opens a  
door you didn't pick and shows you a goat and gives you the  
opportunity to change your choice of a door if you wish. Monty knows  
what door the prize is behind and you do not, so Monty could pick  
the correct door with a probability of 100% but the best you can do  
at first is 33.3%, after he lest you change your choice and pick  
another door you know a little more and your probability increases  
to 66.6%, Monty's probability stays at 100% and the thing itself,  
the new car, has no probability at all.


Incidentally the great mathematician Paul Erdos admitted he could  
never get his head around the Monty Hall problem and it always  
seemed paradoxical to him, this despite him having no trouble  
whatsoever in understanding many other things of staggering  
complexity and of far greater abstraction. It's weird.


He got it eventually, when asked the same question with a bigger  
number of boxes. But there is nothing relevant to the question I am  
asking you.





 so if I told you before the duplication that you would see  
Washington AND Moscow I would be correct, Bruno Marshal will indeed  
see both cities.


 That the 3-view on the 1-view.

And that should be more than good enough thank you very much!


Why did you change Marchal into Marshal in the quote?




 But the probabilities bears on the 1-views themselves.

As I've said many many times before, give me a single concrete  
example of two things being identical by the 3-view but not by  
the 1-views themselves and you will have won this argument, do  
that and I will publicly declare you've made a major philosophical  
discovery. Just one example is all I ask. I think this is the key to  
our disagreement.


The duplication. After the duplication
In the 3 view I am in both cities
In the 1-view I feel oneself in only one city.
Another example is in the step 2.
In fact you ask me what I give in each step, and you don't see it  
because you persistently confuse them.





 You can ascribe the consciousness of Bruno Marshal to both, but  
each one will ascribe their present here and now type of  
consciousness only to themselves subjectively.


Why did you change Marchal into Marshal again in the quote?





I don't know what here and now type of consciousness is. We both  
agree that speaking of consciousness occupying a place in space has  
little meaning and I would argue a absolute time for a consciousness  
is not a productive idea either. You could freeze a mind for a  
billion years and then start it up again and it wouldn't notice it  
unless it has senses that can detect the outside world, and even  
then the mind couldn't tell if it had stopped for a billion years or  
what it was looking at had jumped ahead a billion years.


You confuse consciousness of being here and now with consciousness  
would be here and now.





 Asking why you are the Moscow man not the Washington man is  
exactly like asking why you are Bruno Marshal and not John K Clark.


 Possible. I do agree with this. But there is a difference. John  
and Bruno have already differentiated.

 If the original is cut, the probability to wake up at Helsinki is 0.


But the Helsinki man is not a copy, it's irrelevant to the copies in Moscow
and Washington what happens to the original.

 By comp we can simulate Moscow and Washington precisely enough so that
 you cannot see the difference for some non null interval. The question is
 do you agree that this does not change the evaluation of the
 indeterminacy?


Yes I agree it does not change, this 1-view indeterminacy of yours is
nonsense if the cities are real and its nonsense if the cities are
virtual.

The reason I'm not the Moscow man is that I'm the Washington man and the reason I'm the

Moscow and Washington is 100%. What more is there to say on this rather dull subject?


That you give the probability that the guy will be in W and M from a third person point 
of view, when we ask the probability on his future first person point of view. the 
criteria of confirmation is given, by definition, from the result of the 
self-localization provided by the persons after their duplication.
In that case, it cannot be 100%, because the guy in M does not feel himself to be in W, 
and vice versa.
You still confuse the 3-view on the 1-views (an outsider can ascribe the consciousness 
of John K Clark to both persons in each city), with the 1-views on the 1-views (Ah, I 
see I am the one in W and Ah, I see I am the one in M). In Helsinki, he could not 
know in advance which one he can happen to be. If you think he could, give me the 
algorithm.

or
I have been duplicated in W and M and i feel myself in M.

Right.

 But are equal in the 3-view, where I am in both cities.


WRONG! From my 3-view I can clearly see that the brain of Bruno Washington is different 
from the brain of Bruno Moscow, one has memories, that is to say physical changes in 
the brain, of the sights and sounds of Washington while the other has brain changes 
signifying the sights and sounds of Moscow; because of the changes in physical 
structure the two brains operate differently, or to say the same thing with different 
words, I the third party can see that the mind of Bruno Washington is different from 
the mind of Bruno Moscow.  Provided that Washington is different from Moscow (I've 
never been to Moscow but I imagine that it is) then the brain of Bruno Washington is 
physically different from the brain of Bruno Moscow, and I the third party observer can 
see those physical differences, and if the construction of those two objects are 
different then the way they operate, the mind, is different too.


But this contradict the fact that you agree both person are the Helsinki guy. You are 
again transforming I cannot know for sure I will feel myself in W or M with I can be 
sure that the guy in M will see M and the guy in W will see W, which is does not answer 
the question in asked to him in Helsinki.






Try again. Give me a single concrete example of two things being identical by the 
3-view but not by the 1-views themselves and you will have won this argument.


  Who cares? How is it relevant to the copies if the original is cut 
or not
cut as long as he's read?

 If the original is cut, the probability to wake up at Helsinki is 0.


But the Helsinki man is not a copy, it's irrelevant to the copies in Moscow and 
Washington what happens to the original.


Of course, but the question is asked before the reading is done. The question is asked 
to the guy in Helsinki before the experiment is done. So the probability is 1/3, instead 
of 1/2 in the preceding WM duplication with annihilation of the original.


It is equivalent to a multiplication by three, with a null delay of reconstitution on 
one

It looks like that. Now, in my experience I have rarely met someone

usually consider that any text containing the word consciousness is  
crackpot and rarely try to argue. This makes John Clark rather

You have not shown that. It is non sense for you because you keep

the 1-view themselves (or 1-view on 1-view). You oscillate between  
trivial, non sense, and 100%. I can't figure out what is your  
objection.




and its nonsense if the cities are virtual.


The question is asked. If you believe in comp, you know that after  
the duplication you will not feel to be in two places at once, so  
it makes sense to evaluate (or to try to evaluate) the chance that  
you will be in this or that city. If you say 100% for Washington,  
by definition of the 1-views, the you-in-Moscow will have to admit  
having been wrong, and vice versa.


Likewise, in the multiplication movie experience, the white-noise  
movie is far more probable that seeing any particular movie,  
because the majority of the John K Clark will see such random movie.


Just keep in mind that the question is asked always before the  
duplication experience and that the answer you give before   
the experience is verified by interviewing all the resulting person  
about their personal experiences, not about the experience of their  
doppelgangers.


So I ask you again what is the probability that you will actually  
live the experience seeing the movie flying circus in the  
multiplication movie experience. remember that by definition, to  
verify your answer, I will ask to each John K Clark which movie  
they have actually seen and ask them if that confirms their  
prediction. the answer all movie is already no more possible,  
because you already know, by comp, that you, any of your yous,  
will feel to see only one movie.


I notice that it seems clear enough if you just duplicate the diary.


Right. It is the point of approximating the first person experience by  
the memory or the diary. So it reduces the 1/3 distinction into going  
through the teletransportation or just looking at it from outside.
And for the probability, you can replace the human observer by an  
inference inductive machine. The whole UDA can be done in the third  
person way.





You write This diary will be in Washtington. and then when there  
are two diaries, the one in Washington is right and the one is  
Moscow in wrong.  The diaries don't need to experience anything.  As  
macroscopic objects they have definite spacetime locations and don't  
exist in a M+W superposition.  The use of indicial pronouns only  
produces a little semantic confusion.  I think John's presentation  
of his thought experiment is wrong - although it's logically  
possible, it's nomologically impossible and not just  
technologically.  Creating two copies of a person must be two  
distinguishable copies just by position and instantaneously  
swapping their positions is not nomologically possible.  Somewhat  
the same problem affects the transporter thought experiment.  There  
will necessarily be a discontinuity between the copies and the  
original - both in body and in consciousness.


But such a discontinuity is relative to the implementation, and  
accepted as part of accepting that the brain is digital. So it is not  
clear if consciousness can see that discontinuity, except by the bare  
fact of being in a place and then in another one. More realistic real  
duplication would need encoding time, reconstitution time, but those  
becomes non relevant at the step seven.




I don't think that's fatal to Bruno's argument, but we need to get  
through the argument to see what aspects of the thought experiment  
it actually relies on and which are otiose.


Excellent point. A scientist rarely stops when he does not get a  
point, he always continue, because the next steps can indeed clarify  
what is or not missing, or important, in previous points. The fact  
that John talks like he found a fatal flaw let me suspect he want to  
dismiss the reasoning at the start.

And his tone is ad hominem, which can be a bit boring at time.

I don't want to dream about the number of posts needed to explain the  
step 8 to him ...


And I am afraid he will not appreciate the abstract theory of  
intelligence which profiles on the comp horizon, and which almost  
equates intelligence with modesty ...

The point is that comp predicts white noise.
That something else predicts white noise too is not relevant in the  
proof.







 that you should expect the WM duplication as equivalent with the  
throw of a random coin, etc. But you don't need to agree with that  
analysis. You need only to agree that there is an indeterminacy


Of course there is a indeterminacy!


Don't say of course. That is not so obvious as your posts illustrates.  
After all, officially the thesis has been rejected (in Brussels,  
before it being accepted in Lille) at step 3. This might be enough to  
say that it is new, and not understood so quickly by many.




A key part of your thought experiment is that a million pixels on a  
screen change at RANDOM 60 times a second from black to white for 2  
hours,


In the 3-view there is no randomness at all. In the protocol, we don't  
change the pixels randomly, neither in the comp multiplication-movie  
experience, nor in the quantum wave which evolves deterministically.  
The point is that the randomness bears on the first person  
experiences. We get this directly with comp, without assuming QM.




being RANDOM you can't (or at least should not) be certain what  
you'll see on the screen. If Everett is right the indeterminacy is  
purely a measure of lack of information on your part and that  
information exists you just don't have it. If you knew what branch  
of the multiverse you were in, what particular universe you were in,  
you'd know for certain what you were going to see on that screen; if  
you are in a Monty Python branch you will see a Monty Python movie  
and if you're in a white noise branch you'll see white noise. Once  
again your 1-view indeterminacy brings nothing new to the mix.


What is new is that we get it without postulating quantum physics. It  
is not so new, I publish it in the 80 (and make it public before in  
many conferences).


But the question is not if it is new or not. The question is do you  
get the point of step 3, which shows that comp entails that objective  
indeterminacy on the subjective experiences.


(Note also that objective is used temporarily. later we will see  
that physically objective is not a 1-view, but a 1-plural view. yet,  
at this stage, we can use objective, because it refers only to the  
content of a diary of an outsider looking at the experience without  
doing it himself).





I can hear you say, but that's the point, you don't know what branch  
you are in until you see white noise or Monty Python on that screen.  
But according to Everett until you see something unique on that  
screen that nobody else in any universe sees you are not in that  
branch because that branch does not exist, seeing Monty Python is  
exactly what makes it the Monty Python branch.


There is a little nuance, the one between duplication of worlds or  
differentiation of worlds. But it is not really relevant at this  
stage. So indeed, that's the point. But note that comp does not assume  
QM, yet explains the existence of a phenomenologically similar  
indeterminacy.





 So I think we could move on step 4. You cannot stop in a middle on  
a proof on the pretext that you have learn nothing.


I can understand your desire to gloss over this major difficulty


?
I thought you just grasped it. What major difficulty? The only one you  
have ever mentionned as been shown to be a confusion of 1-view and 3- 
view (or on the 3-view on the 1-views, and the 1-views themselves.  
Reread perhaps the preceding posts).





and move on, but I feel that if a proof has made a blunder it's  
pointless to read more.


Which blunder?






  There is a difference between anything can happen in the  
reality, and anything can happen in the next moment.


And what difference is that?


The conditional probabilities. Everett, and also comp (as you will see  
later) predict that everything (consistent) happens, but with  
different relative probability. If I put water on the gas, there are  
worlds where it freeze, and there are worlds where it boils hot. To  
take a decision I need to have trust that I

As David points out, John Clark did understand step 3, at some point.

Everything predicts that. OK, then I have a marvelous new thought
experiment, let X = Y. I maintain that comp predicts that X= Y and I have
made a wonderful new discovery too.

   you should expect the WM duplication as equivalent with the throw of
 a random coin, etc. But you don't need to agree with that analysis. You
 need only to agree that there is an indeterminacy


   Of course there is a indeterminacy!


  Don't say of course. That is not so obvious as your posts illustrates.


it's not obvious that the outcome of a RANDOM coin flip is uncertain? I
thought it was.

 In the 3-view there is no randomness at all. In the protocol, we don't
 change the pixels randomly, neither in the comp multiplication-movie
 experience, nor in the quantum wave which evolves deterministically. The
 point is that the randomness bears on the first person experiences. We get
 this directly with comp, without assuming QM.


Nothing new. People have only known about Quantum Mechanics for about a
century but they've known about randomness for many thousands of years. And
you've made randomness a measure of ignorance rather than a property of the
thing itself and that's how it should be, and what people have always done.
This is demonstrated by the Monty Hall problem, a new car is behind one
door and a goat behind the other two, you pick a door at random and Monty
opens a door you didn't pick and shows you a goat and gives you the
opportunity to change your choice of a door if you wish. Monty knows what
door the prize is behind and you do not, so Monty could pick the correct
door with a probability of 100% but the best you can do at first is 33.3%,
after he lest you change your choice and pick another door you know a
little more and your probability increases to 66.6%, Monty's probability
stays at 100% and the thing itself, the new car, has no probability at all.

Incidentally the great mathematician Paul Erdos admitted he could never get
his head around the Monty Hall problem and it always seemed paradoxical to
him, this despite him having no trouble whatsoever in understanding many
other things of staggering complexity and of far greater abstraction. It's
weird.

 so if I told you before the duplication that you would see Washington
 AND Moscow I would be correct, Bruno Marshal will indeed see both cities.


  That the 3-view on the 1-view.


And that should be more than good enough thank you very much!

 But the probabilities bears on the 1-views themselves.


As I've said many many times before, give me a single concrete example of
two things being identical by the 3-view but not by the 1-views
themselves and you will have won this argument, do that and I will
publicly declare you've made a major philosophical discovery. Just one
example is all I ask. I think this is the key to our disagreement.

 You can ascribe the consciousness of Bruno Marshal to both, but each one
 will ascribe their present here and now type of consciousness only to
 themselves subjectively.


I don't know what here and now type of consciousness is. We both agree
that speaking of consciousness occupying a place in space has little
meaning and I would argue a absolute time for a consciousness is not a
productive idea either. You could freeze a mind for a billion years and
then start it up again and it wouldn't notice it unless it has senses that
can detect the outside world, and even then the mind couldn't tell if it
had stopped for a billion years or what it was looking at had jumped ahead
a billion years.

 Asking why you are the Moscow man not the Washington man is exactly like
 asking why you are Bruno Marshal and not John K Clark.


  Possible. I do agree with this. But there is a difference. John and
 Bruno have already differentiated. But in the WM duplication experience, we
 duplicate instantaneous computational state by a special duplicator
 machine, so that we can ask the question to the guy before the duplication.


And the only answer you can receive will come from a trivial application of
the anthropic principle, I will become the Moscow man if events transpire
so that I meet the definition of the Moscow man, namely that I see Moscow.

 you can give no examples where according to the 3-view things are
 identical but according to the 1-view they are not, although it's easy to
 find examples where according to the 1-view things are identical but by the
 3-view they are not.


 That's my point.


I really wish it was.

 So you grasp very well the difference between 1-view and 3-view.


Yes.

 so I have no clue what difficulties you seem to have but never succeed to

But non-comp predicts exactly the same thing simply because the number of

 that you should expect the WM duplication as equivalent with the throw of

 need only to agree that there is an indeterminacy


Of course there is a indeterminacy! A key part of your thought experiment
is that a million pixels on a screen change at RANDOM 60 times a second
from black to white for 2 hours, being RANDOM you can't (or at least should
not) be certain what you'll see on the screen. If Everett is right the
indeterminacy is purely a measure of lack of information on your part and
that information exists you just don't have it. If you knew what branch of
the multiverse you were in, what particular universe you were in, you'd
know for certain what you were going to see on that screen; if you are in a
Monty Python branch you will see a Monty Python movie and if you're in a
white noise branch you'll see white noise. Once again your 1-view
indeterminacy brings nothing new to the mix.

I can hear you say, but that's the point, you don't know what branch you
are in until you see white noise or Monty Python on that screen. But
according to Everett until you see something unique on that screen that
nobody else in any universe sees you are not in that branch because that
branch does not exist, seeing Monty Python is exactly what makes it the
Monty Python branch.

 So I think we could move on step 4. You cannot stop in a middle on a
 proof on the pretext that you have learn nothing.


I can understand your desire to gloss over this major difficulty and move
on, but I feel that if a proof has made a blunder it's pointless to read
more.

  There is a difference between anything can happen in the reality, and
 anything can happen in the next moment.


And what difference is that?

 If Everett is right the probability must be derived from the statistics
 of measurements *as described by the wave evolution*.


If Everett is right then you can use the square of the absolute value of
the Schrodinger Wave Equation to help you guess which branch you are in, he
says it's the best guess you can make with the limited information you have
at your disposal, it's not perfect but it's the best we can do. However if
Everett is right everything that can happen to you will happen to you
somewhere in some branch of the multiverse.

 The distinction you are introducing concerns what the outsider can write
 in his diary (the 3-view), it does not bear on the individual diary
 contents (the 1-views).


I see, the contents of the diary are 3-view but the diary contents are
1-view. No I take that back, I don't see.

 After the experience, both concedes that they feel in one city, as they
 describe in their respective diary, and both recognize that they don't feel
 to be in both city, and that they don't feel any possible sensation of
 their respective doppelganger.


And both will record in their diary that they are Bruno Marchal, in fact
they both insist on this point very very strongly, and I the outside
observer can find absolutely no reason to say that one is more Bruno
Marchal-like than the other, so if I told you before the duplication that
you would see Washington AND Moscow I would be correct, Bruno Marchal will
indeed see both cities.

 But n Helsinki you cannot know for sure in which city you will wake up.


Asking why you are the Moscow man not the Washington man is exactly like
asking why you are Bruno Marchal and not John K Clark.

  But exactly what does your 50% really mean? You're treating it not as a
 measure of ignorance


  Well, you can treat it as a measure on ignorance, by using the PUP
 principle.


 I wish you'd stop expecting people to remember what all your homemade
acronyms mean.


  Basically the 1-view is the subjective(*) experience, and the 3-view is
 what an outsider can objectively described.


Then you can give no examples where according to the 3-view things are
identical but according to the 1-view they are not, although it's easy to
find examples where according to the 1-view things are identical but by the
3-view they are not. So when you complain that I'm just looking at things

Thanks for that clarification.  That being said, he is nevertheless
explicit that the crucial distinction between what he wants to suggest
and MWI is that only one branch can be considered as having been
actualised. Given his scepticism about Wallace's analysis of the
probable subjective consequences of duplication, this is what he feels
he needs for his scheme to be plausible in the face of the empirical
facts.

By the way, the reasons he gives for that scepticism seem to me to
imply some sort of individuated crypto-dualism.  For example, he says
that Wallace doesn't address the possibility that future copies
might be subjectively discontinuous with the you that exists
presently; consequently that particular you could be consigned to
subjective oblivion.  He concedes that, whether considered physically
or informationally, the copies possess every feature that presently
determines your empirical self-identification.  The conjunction of
these two stipulations suggests that, despite everything, some
personal essence is not copied; rather, each doppelganger acquires
its own freshly minted personal self-hood, and yours is annihilated.

I've attempted to conceive how one might put this to the test, even in
imagination, but I've not come up with anything.  This kind of rampant
confusion over pronouns is the chief reason I favour the universal
mind heuristic as a way of conceiving the subjective state of affairs.
 In terms of this heuristic, I always denotes the unique but
discontinuous subjectivity of an infinity of self-ordering personal
histories.  Since the subjective locus is not itself subject to
change, every perspective is mine, but not all perspectives are
associated with David Nyman.  It may seem strange at first, but it
unravels surprisingly many of the conceptual puzzles.

 As I said before, the requirement for some principle of selection, in

Dear Bruno,

   I wish I could feel comfortable with such a focused area so that  
we can neglect all other considerations. I agree with your judgement  
about materialists, but am not so sanguine about the idealist as  
having all the answers.



Nobody said that the idealist has all answers. If comp is true, he has  
only all questions, really, so to speak.


What is said is that IF comp is true, then we are necessarily lead to  
arithmetical (or equivalent) idealism. That's the result.


Idealism is not part of the comp assumption. It is part of the  
theorem. Comp has to be idealist.


If you belief, for whatever reason, that idealism is false, then COMP  
is false. You can't survive with a digital, even material, brain, by  
virtue of a physical computer emulating your brain at some level.






My motivations are different from yours. I am wrestling with the  
ontological implications of physics and so our interests cross in  
many places.


Only if comp is part of your theory. I have not yet seen any real,  
precise, non comp theory, so I cannot judge them.



I have proposed an alternative ontology theory that appears to solve  
the mind-body problem without having to resort to epiphenomena,  
which by your own admission infects both materialism and idealism.


You forget many of our discussions. Comp, + the usual Occam, leads to  
the disappearance of matter. Matter does not become an epiphenomenon,  
for its observation becomes a psychological or biological or (better  
imo) theological phenomenon. There are no epiphenomena.


Materialists which are not eliminating consciousness makes often it  
into an epiphenomenon, because they admit it exists. But comp makes  
primitive matter into pure and simple non existence. You can  
reintroduce it logically, and that would make it into an  
epinoumenon, like invisible horses driving car, or ether, or  
phlogistic. That's different.

above? My claim is that a single unified model must obtain and that  
the notion of 1-p identity follows directly from this and thus if no  
unification can obtain neither does a 1-p.  What did you imagine  
that I was claiming? What I have been trying to point out is that  
the single unified model must be such that there are no logical or  
resource conflicts. I go further to claim that this is an example of  
the SAT problem in applied logic. It is known that SAT is an NP- 
Complete problem and thus the computational complexity issues must  
be addressed.
I have been arguing that COMP neglects these complexity issues  
completely and seemingly does so by eliminating the necessity to  
consider the actual physical implementations of the computations,  
preferring instead to postulate some Platonic realm where  
computations have particular properties merely on the basis, it is  
argued, that the truth valuations of Sigma_1 sentences is completely  
independent of our knowledge of their content. I see this as  
equivalent to saying that since there exist strings of numbers that  
are solutions to NP-Complete problems then we don't need to worry  
about actually having to find them and thus bypass problems like  
SAT. Instead we are offered an interesting form of Occasionalism or  
Accidentalism to explain how it is that we actually do experience a  
physical world.



Comp is just the assumption that we are machine, to said it shortly.  
Then it is shown as a consequence that not only we cannot neglect the  
physical reality, but that we have to retrieve it from arithmetic,  
without using any probabilistic *selection*. Comp is the problem, not  
the solution. Only the materialist believe wrongly that comp solves  
the mind problem, and *they* take matter for granted. Pretending that  
comp neglects problem is contrary to the facts, because comp just  
shows precisely where the problems come from (the taking granted of  
the physical reality).

Sure, but even if one believes that to be the case, it is still taken
entirely for granted that there is some natural principle for the
selection of THIS physical system from the class of all such systems.
To appeal, a posteriori, to the fact that one's observational
perspective is apparently associated with this particular system and
not any other is merely to argue in a circle; since that is what we
are trying to explain we cannot adduce it as the explanation.

As I said before, the requirement for some principle of selection, in
this sense, is rarely made explicit, but nonetheless implicitly relied
on.  More often than not our particular localisation in space and time
has been consigned to the realm of psychology or illusion, as in
Einstein's reputed remark, as though it were somehow possible to
disarm this inconvenient observational fact with scare quotes.  So
what intrigued me about Hoyle's idea (and according to Gribbin it was
rather more than a fictional conceit for him) was precisely that his
making it explicit exposed an elephant in the room that few others
were prepared to acknowledge.


Exactly. What comp shows is that each time a physicist use a physical  
law to make a physical prediction, he is using an identity principle,  
a selection principle, and an induction principle, which is  
incompatible with comp. He assumes his mind is attached to one brain  
and that there is no other equivalent brain existing in reality, to be  
able to transfer his 3p reasoning on its future 1-view. Comp makes the  
mind-body problem *more* difficult, by showing that those principles  
are not applicable.

Reality is more subtle than the physicist want us to believe.

Yes, but the universe will be the way is and doesn't care if I favor it or

 You did not answer Quentin when he commented that with Everett the
 Universe is a duplicating chamber, so that your charge again the

In the first place I like Many Worlds for esthetic reasons but I'm far from
certain it's true. More important, in the thought experiment about the
cities we have access to all the branches and can see what all the copies
are doing, but that is not the case with Everett. If Everett is correct
then probability is not inherent in the event itself but is just a measure
of our ignorance. As you point out Many Worlds is a deterministic theory so
if we had a bird's eye view of everything probability would be a useless
tool because everything would have a probability of 100% or 0%.

But I can hear you scream but you still wouldn't know for certain if you
will see Washington. I say the probability is 100% you say it is 50%, how
can we tell who is correct? I say that after the experiment if I find you
and you says that he is in Washington and only Washington then my
prediction was proven correct, and I can do exactly that. If after the
experiment if you find you and he says that he is 50% in Washington then
your prediction was proven correct, but you can't find anybody like that.

You concede that you will indeed say you are in Washington and only
Washington, but you correctly point out that you will also say you are in
Moscow and only Moscow. I agree and say that means the probability you will
see Moscow and only Moscow is also 100%, but you disagree and say it is
50%. I say the fact that you say you are in Washington and only Washington
in no way weakens the claim that you are in Moscow and only Moscow.

I predict there is a 100% chance there is a 100% chance you will feel like
you are in one city and one city only, and it's not a problem for me to
have two yous with 100% because YOU HAVE BEEN DUPLICATED. But exactly what
does your 50% really mean? You're treating it not as a measure of ignorance
but as if it's part of the thing itself even though it's a deterministic
process, as if there is a 100% chance you will feel like you are 50% in
Moscow and a 100% chance you will feel like you are 50% in Washington. And
that does not correspond to the experimental results.

  My complaint is that the diaries add nothing, it's obvious that if the
 diaries the people remember writing are identical then the people are too,
 and if they aren't then the people aren't either.

 that both the guy in W and in M have the right to say that they are the

True it does make sense, the Washington guy is the Helsinki guy and the
Moscow guy is the Helsinki guy and the Moscow guy is not the Washington guy
and the Washington guy is not the Moscow guy. It's all very clear, but
where did I contradict myself?

 And to add to the confusion sometimes you admit that they would feel the
 same, but then in your next breath you start talking about how it's
 identical in the 3-view but not the 1-view.


  Could you quote me and be more precise.


Bruno, 3-view and 1-view are your terms, you invented them not me, if

if you thought the two things were identical then why the hell did you go

 In the step three experience we are talking about, they will give quite
 different answer.


Then obviously they become different people and the thought experiment
becomes rather dull.

Dear Bruno,

I wish I could feel comfortable with such a focused area so that we 
can neglect all other considerations. I agree with your judgement about 
materialists, but am not so sanguine about the idealist as having all 
the answers. My motivations are different from yours. I am wrestling 
with the ontological implications of physics and so our interests cross 
in many places. I have proposed an alternative ontology theory that 
appears to solve the mind-body problem without having to resort to 
epiphenomena, which by your own admission infects both materialism and 
idealism.

 I would expect to feel exactly the same as if duplicating chambers and

Q.E.D.  This is the entire point of step 3.  To repeat, in your own
words above I would expect to feel exactly the same as if duplicating
chambers and multiple copies of myself were not involved.  Indeed, if
you had reason to expect to feel anything else, that alone would force
you to abandon both MWI or comp, as Adrian Kent argues forcefully in
the papers Brent referenced.

Kent quotes David Wallace's three logical options for the subjective
consequences of MWI branching, of which the first (separately located
simultaneous consciousnesses) and third (oblivion) clearly are at odds
with your expectation to feel exactly the same as if...multiple
copies of myself were not involved.  Wallace agrees with you - as he
puts it, the remaining option is I should expect to become one or the
other future self.  This implies, he goes on to say, that in the
absence of some strong criterion as to which copy to regard as
“really” me, I will have to treat the question of which future self I
become as (subjectively) indeterministic.”

The alternative to this analysis is to abandon MWI (or comp) as
inconsistent with the empirical facts.  This is the tack Kent in fact
adopts, proposing a mechanism for the pruning of all but one of the
alternative branches, in the absence of which he clearly feels the
empirical facts cannot be justified.  I don't happen to agree with his
reasons, but such a proposal is consistent with his view of the likely
subjective consequences of duplication.

I hope you can now see that Kent and Wallace both formulate the issue
of duplication equivalently to step 3 of the UDA.  Assuming that,
unlike Kent, you don't wish on this basis to rule out the MWI or comp
hypotheses, the first-person indeterminacy with respect to
duplication is equivalent to what Wallace describes as treat(ing) the
question of which future self I become as (subjectively)
indeterministic.”

I agree. But the experience is lived as unique, so we can follow  
Plotinus in using the term soul for the owner of the 1-view, that  
is, the knower. From its pov, it is not duplicable, in the trivial  
sense that the duplication is never part of his experience.


You don't know that.  It's an assumption based on the idea that  
conscious experience is something a certain physical body, a brain,  
does.  But if conscious experience is a process then it is certainly  
possible to create a process that is aware of being in both

I do not define consciousness, and for the reasoning I am using an

I am not sure the problem of probability is identical in QM and  
COMP. In QM, Everett showed that the P = A^2 principle does not

I don't think that's correct.  'A' is the amplitude of the

projection produces different A's.


No problem with this.

finite multiverse, but it works with infinite multiverse,


But infinite multiple worlds create a measure problem.  That's one  
of Adrian Kent's points.


In all case of multiplication, be it through comp or QM, there is a  
measure problem. With comp, the mind-body problem is transformed into  
a justification of the physical laws through a measure problem.

 Surely it's just a necessary prerequisite for accepting the
 possibility of either MWI or comp?  IOW, if one rejects, on whatever
 grounds, that a unique subjective perspective could be consistent with
 the objective existence of multiple copies (as I think is the case
 with Kent) then one is forced also to reject both MWI and comp.  Given
 such a view, neither theory could be a viable explanation for one's
 lived experience of observing one universe at a time.

 AFAICS, the more exotic examples you give above, e.g. a distributed
 process, or a Borg-type group-mind, present no difficulties beyond
 that for ordinary consciousness.  Again, either one accepts that
 duplication of these states of affairs would be compatible, mutatis
 mutandis, with the corresponding single universe perspective
 (however exotic) or not.

 Given the above, what makes it difficult to make sense of John's
 objections to Bruno's argument is precisely that he accepts the
 possibility of multiple copies in a comp or MWI scenario, whilst
 ignoring the necessity of recovering a singular perspective.  But the
 latter step is a prerequisite, in any scenario, for reproducing the
 empirically uncertain state of affairs.  Without it, the probability
 of every outcome - as John has continually reiterated - can only ever
 be 100%!

 Selection, even if only implicit, is an ineliminable feature of any
 theory seeking to explain the empirical facts.  Kent's proposal is a
 process that eliminates all branches but one, albeit on a somewhat
 different basis than Copenhagen.  Similarly, the heuristic I suggested
 in an earlier post entails selection, but in a non-destructive
 manner.  BTW, I had long retained a dim recollection of a similar
 selection metaphor involving pigeon holes from my youthful SF
 reading, which I recently re-discovered to be Fred Hoyle's 1960's
 novella October the First is Too Late.  I also found that John
 Gribbin refers to this very notion in his recent Multiverse book
 (apparently he was a student of Hoyle's), relating it to the ideas of
 Deutsch and Barbour.  This reinforced my suspicion that they do rely
 implicitly on such a selection principle, though AFAICS neither of
 them acknowledge it explicitly.

 My reading of Kent is that he rejects MWI.  I don't think he believes there
 is a single conscious copy and the rest are zombies; he believes there's
 just one world and it is 'selected' probabilistically.

Yes, I understand that.  My point is that Kent disbelieves (as his
arguments contra Wallace show) that a single conscious perspective is
either logically or naturally consistent with the objective existence
of multiple copies, and it is this disbelief that motivates his
suggestion of an objective selection process to dispose of all but one
of them.  By contrast, the heuristic I suggest (i.e. an informal way
of thinking about the situation) is subjective (albeit impersonally
so) rather than objective, in the sense that it doesn't involve
eliminating the unselected branches.  It is curious to me that
others have seemingly dismissed this possibility because of the
apparent threat of zombies, or what David Albert somewhat gothically
refers to as mindless hulks.  But there is another way to conceive
this.  In essence, it's the perspective of a universal consciousness
with amnesia for states other than those associated with the momentary
selection of a current history.

From this perspective, other people with whom we interact (including
our own bodies) stand in approximately the role of avatars in a video
game.  It is highly relevant in this regard that the
empirically-discoverable game physics never requires the presumption
of conscious states (or indeed anything else outside its own closed
system of transformation rules) in order to explain their behaviour.
The selection of mutually-exclusive moments by the universal mind
might imply that only one of these avatars is conscious at one time,
but on reflection this corresponds rather precisely to what we are
trying to explain.  Subjectivity is never simultaneous as
experienced (which is equivalent to the claim that it can't be
duplicated); the ability to synchronise clock times between different
(objectively characterised) subjects is a different matter.

The problem with all this (as Kent makes explicit) is that there is
nothing in the mathematics of the game physics that corresponds to
this kind of momentary selection of subjective localisation.
Unfortunately, his own proposal doesn't really solve the underlying
problem, because although it can account, given the experimental
situation, for my seeing spin-up and not spin-down (because the other
doesn't objectively exist any longer) it cannot account for why the
experience is of David making this observation rather than Brent, or
indeed here rather than there, or now rather than then.  Subjective
localisation is simply assumed, or trivialised, as in Einstein's
remark “The distinction between past, present, and future is only a
stubbornly persistent illusion”.

 Given the above, what makes it difficult to make sense of John's
 objections to Bruno's argument is precisely that he accepts the
 possibility of multiple copies in a comp or MWI scenario, whilst
 ignoring the necessity of recovering a singular perspective.


 But in Bruno's transporter experiment there isn't *a* singular perspective,
 there are two different ones.

Now you're doing a John!  Sure, there are two different ones
objectively, but there's only one subjectively.  Unless you want to
take the tack of rejecting comp or MWI on that basis (which is a
possibility) this forces you to accept that the existence of two
copies must indeed (somehow) be compatible with your experiencing a
single perspective.  The heuristic I propose makes this unproblematic
AFAICS, though it does indeed force re-consideration of exactly who
you are, and invokes the measure problem with particular
vengeance.  But that is unavoidable, ISTM, with any proposal in this
domain, as indeed is the determination of subjective localisation as
an ancillary assumption.

 Selection, even if only implicit, is an ineliminable feature of any
 theory seeking to explain the empirical facts.

 But then Everett's QM doesn't explain the facts - because there is no
 selection.  That's part of Kent's criticism.

I agree.  It can't explain the facts without selection, on which it
relies implicitly (and I don't understand why this doesn't strike more
people as problematic).  But I also don't believe that Kent's proposal
on its own goes all the way to dealing with the deficiency he exposes,
as I explain above.

Thanks for reminding me of this - I hadn't read Leibniz for a long

instance of his referring to selection:

53. Now as there are an infinity of possible universes in the ideas
of God, and but one of them can exist, there must be a sufficient
reason for the choice of God which determines him to select one rather
than another.

This could perhaps be interpreted as being consistent with Kent's
proposal of an objective selection at infinity pruning out the
superfluous branches.  But if so, it is still vulnerable to my
criticism that it fails to account for subjective localisation, or in
Leibniz's terminology, why the subjective perspective of one monad is
selected at a given moment rather than another.  Can you direct me
to any other reference to this in the Monadology?

 Surely it's just a necessary prerequisite for accepting the
 possibility of either MWI or comp?  IOW, if one rejects, on whatever
 grounds, that a unique subjective perspective could be consistent with
 the objective existence of multiple copies (as I think is the case
 with Kent) then one is forced also to reject both MWI and comp.  Given
 such a view, neither theory could be a viable explanation for one's
 lived experience of observing one universe at a time.

 AFAICS, the more exotic examples you give above, e.g. a distributed
 process, or a Borg-type group-mind, present no difficulties beyond
 that for ordinary consciousness.  Again, either one accepts that
 duplication of these states of affairs would be compatible, mutatis
 mutandis, with the corresponding single universe perspective
 (however exotic) or not.

 Given the above, what makes it difficult to make sense of John's
 objections to Bruno's argument is precisely that he accepts the
 possibility of multiple copies in a comp or MWI scenario, whilst
 ignoring the necessity of recovering a singular perspective.  But the
 latter step is a prerequisite, in any scenario, for reproducing the
 empirically uncertain state of affairs.  Without it, the probability
 of every outcome - as John has continually reiterated - can only ever
 be 100%!

 Selection, even if only implicit, is an ineliminable feature of any
 theory seeking to explain the empirical facts.  Kent's proposal is a
 process that eliminates all branches but one, albeit on a somewhat
 different basis than Copenhagen.  Similarly, the heuristic I suggested
 in an earlier post entails selection, but in a non-destructive
 manner.  BTW, I had long retained a dim recollection of a similar
 selection metaphor involving pigeon holes from my youthful SF
 reading, which I recently re-discovered to be Fred Hoyle's 1960's
 novella October the First is Too Late.  I also found that John
 Gribbin refers to this very notion in his recent Multiverse book
 (apparently he was a student of Hoyle's), relating it to the ideas of
 Deutsch and Barbour.  This reinforced my suspicion that they do rely
 implicitly on such a selection principle, though AFAICS neither of
 them acknowledge it explicitly.

To appeal, a posteriori, to the fact that one's observational

selection of THIS physical system from the class of all such systems.

then what more selection is required?



To appeal, a posteriori, to the fact that one's observational
perspective is apparently associated with this particular system and
not any other is merely to argue in a circle; since that is what we
are trying to explain we cannot adduce it as the explanation.


That seems like conjuring a mystery out of nothing. Is your question why is my 
observational perspective associated with my brain?


Brent



As I said before, the requirement for some principle of selection, in
this sense, is rarely made explicit, but nonetheless implicitly relied
on.  More often than not our particular localisation in space and time
has been consigned to the realm of psychology or illusion, as in
Einstein's reputed remark, as though it were somehow possible to
disarm this inconvenient observational fact with scare quotes.  So
what intrigued me about Hoyle's idea (and according to Gribbin it was
rather more than a fictional conceit for him) was precisely that his
making it explicit exposed an elephant in the room that few others
were prepared to acknowledge.

 We agree on this since the beginning.

Then why why why do you keep talking about things being the same  
from the 3-view but not from the 1-view.


You confuse F(x) = F(y) = x = y, with
F(x) = x.
Identical bodies have identical minds, but identical minds can have  
different bodies.





 It seems to me that you are playing with words.

Words are the only means we have to communicate with and I need to  
know what they mean and that is not always obvious in very extreme  
and unusual (but not illogical) situations.


 But you can see there are 2 bodies of Bruno Marchal just as well  
as the outside observer, and you can not tell which one is you any  
better than the outside observer can!


 No. The outsider can see both necks for example. The insider  
cannot be sure that he is not in front of some mirror, according to  
your own analysis.


No, you can touch the other fellow and he does not feel like a glass  
mirror, you can shake his hand, punch him in the jaw, do whatever 2  
people can do when they meet each other, but if I instantly  
exchanged the position of the 2 bodies you would not notice the  
slightest difference, not from the 1-view or 2-view or 3-view or any  
view, the very universe itself would notice no difference. If  
subjectively it makes no difference and objectively it makes no  
difference then call me crazy but I say it makes no difference.


 So you fail to distinguish the 1-view and the 3-view.

Yes, the universe itself can't distinguish between them and I'm not  
better than the universe.


The universe does not know you are John Clark. You do.

It seems you are eliminating the 1-view, which contradicts your  
agreement on the existence of consciousness. Consciousness is not part  
of any 3p description of the universe, yet it exists. I begin to think  
your problem is not with comp, but with the general issue of the mind- 
body problem. Your acknowledged difficulties to see Nagel points on  
the bat corroborates this.
The difference between the 1-view and the 3-view is as big as the  
difference between the diary of the W-man, and the diary of the M-man.





 OK. So what is new with comp is a form of indeterminacy which even  
in theory we cannot predict, and which does not rely on physical  
experimentation and extrapolation, nor on the same anti- 
diagonalization used by Gödel or Turing.


So in this hypothetical non quantum mechanical non Godel-Turing  
universe I could know at least in theory with 100% certainty that I  
will see Washington provided the universe was also simple enough for  
me to know the initial conditions and simple enough for me to  
calculate with them to obtain a outcome.  And because I'd know I  
would see Washington I would know with 100% certainty that I will be  
the Washington man. I ask again what is new or deep here?


You are just wrong. If you predict that you will feel to see  
Washington with 100% chance, the guy in Moscow will have all the  
memories of that prediction, and will have to admit he was wrong.







 Never say cannot be proven without adding by a specific machine  
M


There are true statements that cannot be proven by a machine that is  
both consistent and complete, and any machine powerful enough to do  
arithmetic can not be complete.


 You want to know what is the probability you will become the  
Moscow man, but the only way that can happen is if you see images of  
Moscow, that's what being the Moscow man means.


 You can apply that argument to the throwing of a coin. That  
contradicts the statement above that you can use probability for the  
coin, so why can't you use it for the probability of feeling to be  
the Moscow man?


In common usage when you say what is the probability I will see  
heads when I flip this coin? there is not a 100% chance I will see  
heads as there is in the thought experiment with the cities, but  
even more important in everyday use it is not needed to make what

If the guy in Helsinki has enough cognitive ability todo the thought

Comp is just a modern version of Descartes Mechanist assumption. I  
called it also digital mechanism. I make it more precise by  
introducing the notion of substitution level, and in making explicit  
it is a statement about consciousness. Up to now, you have used  
correctly comp (you just mess the notion of 1 and 3 person).
Comp is the hypothesis that we have a body and that we can survive a  
digital substitution of that body. There is no limit on what that body  
needs to be except for being Turing emulable. I sum up by a yes  
doctor scenario, which gives an operational notion of comp  
practitioner, and which is handy for the thought experiment.
To be completely clear on the notion of digital, I make explicit the  
Turing-Post-Church's thesis, and the minimal amount of arithmetical  
realism needed to give sense to that thesis.

That few people are aware of the consequence of comp is not

Sure. This is even exemplified by the WM duplication. For the guy in

Same for the guy in M.


Logic per se does not even concern events and cause, just valid or

Nice to hear that. So you do see the difference between the 1-POV and

To be sure I would not follow Quentin in calling them frog and bird,  
because it gives an impression that it is a question of scaling, when  
it is more a question of personal points of view (which are modeled by  
modal logic through the self-reference in AUDA). Tegmark used frog and  
bird in the sense of:  described by a term (the frog) of a quantum  
wave superposition, and the whole wave itself (the bird). Comp  
suggests that the quantum indeterminacy might be a particular case of  
the classical comp-1-indeterminacy, but this is not yet proved, and  
besides the whole UDA will show that if QM is correct, then it has to  
be that case, with the price of having to derive QM from the global  
computationalist indeterminacy, that is the one bearing on the  
universal dovetailing or elementary arithmetic. But this needs step 7.

You don't know that.  It's an assumption based on the idea that conscious experience is 
something a certain physical body, a brain, does.  But if conscious experience is a 
process then it is certainly possible to create a process that is aware of being in both 
Washington and Moscow at the same time.  Think of a brain wired via RF links to eyeballs 
in M and W.   Or The Borg of Star Trek.  Of course that experience would be strange and we 
would tend to say, Yes but it's still one consciousness.  So then the question becomes 
what do you mean by not experiencing duplication?  Is it a mere tautology based on how you

chosen, but the projection produces different A's.


so that A can be considered as measuring the relative proportion of possible accessible

 I agree. But the experience is lived as unique, so we can follow Plotinus

 From its pov, it is not duplicable, in the trivial sense that the
 duplication is never part of his experience.

Hi David and Brent,

I have a question. Could it be that the sense of self as 
being-in-the-world (ala Nagel's bat) is a phenomenon not at all unlike 
the uniqueness of a fixed point 
http://en.wikipedia.org/wiki/Fixed_point_%28mathematics%29 on a 
manifold? It seems to me that one of the key aspects of the sense of 
self or I that it is unique in its association with its location and 
its memories. Being in two places at the same time would at least be 
confusing, Try navigating with a combination of two maps - overlay the 
maps of Washington and Moscow and try to figure out where you are.


I offer the movie 12 Monkeys 
http://en.wikipedia.org/wiki/12_Monkeys as a fictional narrative 
exploring what happens when one's localization is split in the time 
sense. In my studies, I have considered how the various pathologies of 
consciousness sketch for us some of the fundamental aspects of 
consciousness in a 3-p'ish way. For example, the various dissassociative 
disorders ranging from phantom limb to multiple personality disorders 
and schizophrenia tell us that an individual's sense of self is strongly 
correlated with the synchronization of both temporal and spatial queues 
both internal to the brain and of a person's location. Thus being in 
two places at the same time is not that much different from having two 
sets of sense data that are disjoint (in the being in Moscow and 
Washington) such that unless a single reconciliation of the two is 
possible, there will be inevitably a splitting of the I's or 1-p.
BTW, this line of reasoning argues strongly against the Borg 
group-mind idea as possibly yielding a consciousness of the same kind as 
the one that we have because of the inability to define a single point 
of view given the wide and even disjoint nature of the panorama of 
sense data that would be involved. Consciousness is, I argue, fixed to a 
single point and cannot be distributed. Distributed behavior would more 
correlate to what the psychologist like to call the unconscious.

the Man in Moscow, but those ideas are considerations of individual 
snapshots and we have a movie to explain. We are many disjoint 
observers, each in our very own version of a universe and yet have the 
illusion that we are all in the same space-time... Maybe our universes 
just are similar enough that we happen to be able to agree on facts 
... Nevertheless, even taking Bruno's COMP seriously, we cannot all be 
one and the same computation for it can only have one and only one 
inside view.

Location is just part of one's model of their body.  If you had two

On the contrary, we are talking on both. Indeed we are interested in

behaving in a Brunomarchalian way. And you Bruno Marchal can not

 The difference between the 1-view and the 3-view is the difference  
between a body and the private experience of the owner of that body,  
or bodies in case of identical bodies.


The outside observer can not distinguish 2 conscious beings inside

I agree it is impossible, so this distinction between 3-view and  
1-view that is so important in your proof turns out to be rather  
silly.


How does this follows?

What you say amounts to the following fact on which we both agree:

3-Body(A) is sufficiently similar to 3-Body(B) entails that  (1-view-A  
= 1-view-B)


And we also agree that the reverse is false:  (1-view-A = 1-view-B)  
does not make (3-Body(A) similar to 3-Body(B)).


Many posts you sent illustrates that you agree with this, and so you  
do get the point of the difference of the 3-view and the 1-view, so I  
fail to see any problem in the use of those notions.







 They are different because one live in W and the other live in W.

I previously said that it is probably meaningless to talk about the  
position of a consciousness and you agreed with me, so all the above  
means is that one consciousness forms memories caused by images of  
Moscow the other forms memories caused by images of Washington, the  
images are different so the memories are different, so the  
consciousness of the two is different so they become different people.


Yes.



The thing that differentiates the minds is not position but  
different memories, if Washington and Moscow were identical cities  
then there would still be just one consciousness, but the cities are  
very different so the two minds are two. Everybody agrees that if 2  
minds are different then there are 2 different minds, but I insist  
that if 2 minds are identical then there is really only one mind  
(not to be confused with brains)


Yes. Note that later we might still say one mind, but put different  
weight on them. This will lead to open questions, and they are  
premature here. So I agree with you, but warn that we can add some  
nuances which might play a role in the comp 1-indeterminacy measure  
problem. But I agree with all what you have said up to here, except  
the wrong attribution.




while your proof is built on the assumption that if 2 minds are  
identical they are still distinguishable at least to themselves,


Like this for example. That's non sense. I have never said that, nor  
does that play any role in the 1-indeterminacy. The 1-indeterminacy  
bears explicitly on the future different experiences. That should be  
obvious: if the experiences reains the same, the probability question  
cannot even be asked.




and that is the reason I don't think its productive to study your  
proof after that point.


... because you attribute me an idea I have never asserted, and which  
would already contradict the definition I gave for comp.






 No 1-view can be duplicated.

Why the hell not?


Exactly for the reason you insist yourself so much on. The 1-view is  
always one mind, which is identical with itself from his 1-pov.






 Both people in the two cities feel one and entire.

Both people will feel IDENTICALLY until differences between Moscow  
and Washington cause them to form different memories.


Exactly, and that is what gives sense to the question in Helsinki:  
where will I feel to be tomorrow?. The question makes sense because  
comp makes you surviving the duplication, one and entire, somewhere.


All what you say entails that in Helsinki the guy can understand that  
there is some certainties, like I will feel to be in M or in W,  and  
I will not feel to be in the two places simultaneously, If I say  
that I will feel in W, then the me in M will rightly consider that I  
was wrong, etc. Then, with this precise protocol, or its iteration,  
you can deduce that the guy is maximally ignorant on W or M, and can  
put a uniform measure of probability on the set {W, M}. That is P = 1/2.






 There is a sense for the guy in W to say that he has been  
annihilated in Helsinki and reconstituted in W.


 Then you get annihilated every time you get on a bus going from  
point A to point B. Do you really want to say that?


 That will be indeed a consequence of comp. It can be said that  
quantum mechanics, which I do not assume, *confirms* that aspect of  
comp. Good point.


So you have redefined the word annihilated so that it now means  
pretty much nothing at all, and thus  we will need to invent a new

  Dear Joseph,

 I first must say that I appreciate very much this exchange as it
 forces me to better refine my wordings and explanations. In the passage
 above I was trying to get at something that I see in the implied structure
 of numbers, given Bruno's amazing ideas. Remember, I think in pictures,
 so the relations between numbers - with their Goedelizations and Loeb
 references - is to me a network where any one entity - here an integer - is
 defined by and related to all others. It looks like the structure of an
 infinite Webster Dictionary!  What I also see is that the links are not
 of a constant length - some connections between numbers are tiny - like the
 link between prime pairs - while others are infinitely long. What I am
 trying to point out is that this structure, is very much* unlike* the
 structure that we think of when we just consider the number line where
 such a line is made up only of integers - 0, 1, 2, 3, ...


  This is all nice, but I can't understand it unless you give make this
 more formal/precise.


 Do you only think in words? I'm just curious... I will try harder to
 sketch the idea in words for you.


I do tend to think more in words or symbols than in pictures, but my intent
here is really just to get a precise understanding of what you are saying.
I hope you agree that this is necessary!



 Think of how Goedelizations and Goedel numbers work as a visual
 picture, perhaps as a poitrait by Matisse or Dali. We have a string of
 numbers that represents another set of numbers *and* some arithmetic
 operation on those numbers. Any such Goedel number is thus the equivalent
 to a handle on the space of numbers (which is, by definition, a one
 dimensional manifold http://en.wikipedia.org/wiki/Curve#Topology, also
 see 1 http://en.wikipedia.org/wiki/Evenly_spaced_integer_topology and 
 2http://en.wikipedia.org/wiki/Open_sets#Topological_spaces),
 therefore if it is possible to have an infinity of goedel numbers in the
 integers then the resulting manifold would an infinity of handles (disjoint
 manifolds) on it. How many unique paths would exist on such a manifold?
 What is the average length of a path? (Please recall the fact that a
 handle can have any size iff it is simply connected and analytic) There is
 no such an average for the only faithful sample of the set of possible
 lengths of paths is the set itself (infinite sets are isomorphic to any of
 their proper subsets).
 Remember that we can also have goedel numbers operating on (mapping
 into) dovetailed strings of goedel numbers and goedel numbers can have
 arbitrarily long number string lengths.. This makes the dimension of
 this manifold to be infinite because of the disjointness of the handles
 that are induced by the Goedelizing, thus making it (modulo the
 requirements of spaces to exist) an infinite space. It is only if the
 requirements of a 
 spacehttp://en.wikipedia.org/wiki/Space_%28mathematics%29not being met that 
 this would not occur. Given that a geodelization
 introduces arithmetic into the set of numbers then is automatically
 qualifies a goedelized number line to be the dual of a space (via the Stone
 representation 
 theoremhttp://en.wikipedia.org/wiki/Stone_representation_theorem
 ).


Thanks for being explicit. But as I have said before, you fail to convince
me of the relevance of these mathematical gymnastics. I can see what you
are saying, but it does not seem insightful to me.



 QED.

 The visual mode and the symbol mode of languages seem to have a
 strange conjugacy





  Numbers as Bruno is considering them, I contend, has a structure
 that mathematicians denote as non-well founded in the sense that there is
 no basic building block out of which this structure is constructed unless
 we force it into a very tight straight jacket. One example of just a
 constraint occurs when we think of numbers as von Neumann 
 numeralshttp://bmanolov.free.fr/von-neumann-integer.phpor something like:

 I mean that's the pont of the step 3

And that's why I think it's a waste of time to even read step 4,  
it's built on a distinction without a difference.


Where is such a thing? The 1-difference does not come from the 3- 
difference between the copies, but between their reconstitution in  
different places.






 The point of the whole UDA is to understand that physics is a  
branch of arithmetic/computer science.


As I said before, although I'm not certain I think you could very  
well be right about that, but you have not proven it because in your  
proof you make a assumption that is not only far from obvious but  
one that I believe is downright false, the assumption that 2  
identical consciousness are not identical and thus need different  
names, like view-1 and view-3.


I don't do that assumption. Tell me where. You have introduce that  
idea, in a different thought experiences, and I said that I agree with  
you. It is just non relevant.







 when the diaries diverge the person will too and become 2, both  
are the original person and neither is each other.


 Correct. That is part of the explanation of the comp indeterminacy.

I'm glad you agree that the one becomes 2 during the duplicating  
process, then obviously you cannot predict a single unique  
occurrence that those 2 things will experience because no such thing  
exists to predict,


Of course those things exist, because the copies, by comp, are not  
zombie, and, by comp, have both the same right to claim to be the  
original. They are different because one live in W and the other live  
in W.




two things can not be unique. All you're really saying in this 1- 
indeterminism stuff is that 2 is not equal to one, you can not put 2  
things (like you) into a one to one correspondence with one thing  
(like Moscow or like Washington).


I might say that indeed. I just make it more precise. And explain the  
consequences.




All your confusion stems from the fact that you say I have been  
duplicated but don't really mean it and still assume there is only  
one I. You say Bruno Marchal will feel he is in Washington only  
and Bruno Marchal will feel he is in Moscow only but I will feel  
like he is in one city and one city only, and that would be true if  
there were only one I, but there is not because *YOU* HAVE BEEN  
DUPLICATED.


This does not make sense. No 1-view can be duplicated. Both people in  
the two cities feel one and entire. So they can say I have been 3- 
duplicated (like my body in Helsinki has been duplicated), but they  
will add but now I feel one and entire in W, and I could not have  
predicted that.
The same, but more strikingly, with the movie-multiplication. Each  
resulting copies will say I have been 3-multiplied every 1/24 second  
for 90 minutes, but my personal experience is that I have seen one  
definite and precise movie, and I have no clue how I could predict  
which one I was about to see personally.






 There is a sense for the guy in W to say that he has been  
annihilated in Helsinki and reconstituted in W.


Then you get annihilated every time you get on a bus going from  
point A to point B. Do you really want to say that?


That will be indeed a consequence of comp. It can be said that quantum  
mechanics, which I do not assume, *confirms* that aspect of comp. Good  
point.




 if you grasp the 1-indeterminacy, you grasp step 3,

I grasped indeterminacy long before I started talking with you, but  
you claim that 1-indeterminacy is different from 3-indeterminacy  
and from physical indeterminacy and from mathematical indeterminacy  
and your claim is based on nothing more than the fact that the  
number 1 is not the same as the number 2.


Like you were thinking that there is only one kind of random string,  
you seems to believe that all indeterminacy are equivalent. But  
phenomenologically identical indeterminacy does not need to have the  
same 3-explanation.

In conventional sciences a 'theory' is taken seriously upon

What do you mean by established science? I don't believe that make

This is how I ended up with many of my patents. For the same reason

I don't see the problem with the word theory, but you can call that  
a narrative if you prefer. You are right that the popular media  
confuse theory and knowledge, but for me it is a reason to use the

is a kind of computation


It is not exactly that, but OK. Comp is really just yes doctor. A  
belief in a sort of possible reincarnation. It is better to see it  
that way, so that we don't need to decide, in the attempt to figure  
out what matter and consciousness is, between what is Turing  
computable and what is Turing recoverable through the first person  
indeterminacies. I currently tend to think that consciousness is not  
Turing computable, but 100% Turing recoverable. Consciousness is the  
quintessence of the 1-view.



then diverging computations would produce the same kind of  
uncertainty that QM does in the MW interpretation.  However, that  
doesn't solve the problem it just makes two problems the same.


Well, assuming both COMP, *and* QM.

So we don't know that yet.

COMP makes the problem more complex, because the SWE itself has to be  
explained phenomenologically or epistemologically. If both COMP and QM  
are correct, then UDA proves the existence of a deduction of QM from  
COMP, that is from the comp TOE of your choice, like the tiny sigma_1  
complete fragment of arithmetic.


The advantage of comp is that if you accept the knowledge notion given  
by Theaetetus then COMP explains both the quanta and the qualia (by  
the divine hypostases, the intensional variant of G* minus G).  
Technically the quanta seem to appear there, and this makes the quanta  
into first person (plural) notion, which is confirmed by Everett's  
multiplication of populations of persons, the contagiousness of the  
linear superposition. At the bottom of what is observable, the linear  
rules, comp-apparently.


Unfortunately, the arithmetical quantization [] p is written in Z1*,  
that is precisely that [] p is Bp  Dp, that p is, dually, Bp v Dp,  
so that []p is [](Bp v Dp) = B(Bp v Dp)  D(Bp v Dp), and then to  
translate some Bell inequality, you need to evaluate formula nesting  
the quantization ([] ([]  # ...), which makes most quantum logical  
assertion of that complexity still untractable today, despite the  
decidability of Z1*).


Bruno


In Everett's MWI there is a problem saying what probabilities mean,  
which is just the same as the one in the transporter thought  
experiment(c.f. arXiv:0905.0624v1 by Ardian Kent).

Socrates asked to Theaetetus to define knowledge. Theatetus gives  
many definitions that Socrates critizes/refutes, each of them. One  
of them consists in defining knowledge by belief, in modern time  
the mental state, or the computational state of the belief and the  
knowledge is the same, and a belief becomes a knowledge only when  
it is (whatever the reason or absence of reason) true. Another one  
is the justified true belief, which is the one which you can  
translate in arithmetic with Gödel's predicate. You can read Bp   
p by I can justify p from my previous beliefs AND it is the case  
that p. To give you an example, if the snow was blue, a machine  
asserting snow is blue can be said to know that snow is blue.  
Indeed, the machine asserts the snow is blue, and it is the case  
that snow is blue (given the assumption).


The problem (for some) with that theory is that it entails that,  
when awake, we cannot know if we are dreaming or not, although in  
dream we can know that we are dreaming, the same for being not  
correct. It is not a problem for comp which makes that ignorance  
unavoidable.


For a machine that we know to be arithmetically correct, we know  
that Bp and Bp  p are equivalent. Yet, the machine cannot know  
that about herself, and the logic of Bp and of Bp  p are  
different. They obeys to the modal logics G and S4Grz, but I guess  
you need to read some book or some web pages to see what I mean here.


I find your explications of knowledge to be confusing.  You refer to  
Theaetetus who said knowledge = true belief.  But in your modal  
logic formulation B stands for either provable or proven  
(Beweisbar).  Provable and believed are too very different things.


Hmm... I am just using Dennett's intentional stance toward machine. A  
machine believes p, really means only that the machine assert p.
I limit myself to machine having their beliefs closed from the modus  
ponens rule, and obeying classical logic, and applying classical logic  
on their description etc. I limit myself on classically self- 
referentially correct machine with respect to some other possible  
machines or oracles.





I think that knowledge consists of a belief that is both true and  
causally connected to the thing believed (c.f. Gettier's paradox).


That is not incompatible with the Theaetetus' idea. Somehow the whole  
problem is there.




  Of course belief that is held because the proposition is proven  
from some axioms does have a causal connection to the axioms.


Yes. And the axioms can be any successful memes in the way to  
unravel a difficulty. Axioms which solves many problems and many class  
of problems can win local games.


I identify partially a person with the set of its beliefs. More  
concrete person can revised beliefs (normally), which is not used  
here, given that I restrict myself of the math of the correct machine.




But that is more than just believed.


Because you talk from the point of view of a much more complex  
consistent (let us hope) extension, viewed at some level.
For the interview I limit myself to an apparently simple machine with  
beliefs, that we all believe in (I hope).






The problem then arises when you say things like, We know there are  
true but unprovable facts about arithmetic.


No. About the machine. Sometimes that machine is Peano Arithmetic,  
because it is the better known Löbian theory. It is an axiomatizable  
theory, which means, by a theorem of Craig, a recursively enumerable  
set of beliefs.



We only 'know' those things in different meta-system where they do  
have a causal connection to  other axioms we hypothesize as true.


Of course. The points is that the Löbian machine does that too, and  
can even do it for themselves. This gives them ability to climb the  
constructive transfinite, and to develop talks and mind tools from  
beyond the constructive.



But ultimately we cannot 'know' that axioms are true - as you say we  
just bet on them.


I think so. Even unconsciously, when our brain conceptualizes that  
there is a reality behind the back of the computer screen. We  
extrapolate all the times, and we have partial controls and partial  
responsibilities and those kinds of things.


The nice happening here is that by the incompleteness, Bp can't be  
confused with Bp  p. By incompleteness Bf does not imply f, so Bf is  
not the same as Bf  f. (Beliefs can be wrong. Knowledge can't, by  
definition).


This shows that the same set of believed arithmetical sentences can be  
seen from many points of views. They provide an arithmetical  
interpretation of Plotinus, through what happens when a universal  
machine looks inward.


It applies to us, tangentially, as far as we are self-referentially  
correct ourselves, tangentially.

 OK, nice. Many confuse comp (I am a machine) and digital physics

A computer's 1p reality would be digital physics though. If I am Super

says that Super Mario will doubt his reality is digital, which I would
agree with if I believed comp. Super Mario's reality could be a
machine or not a machine but his 1p of it is digital because I, as
programmer, have 3p views of its digits.

Of course, I say there is more to it than that: In fact Super Mario
has no 1p at all, and is only a 3p avatar simulating our own 1p world
semiotics. Our own 1p actually permeates 3p because sensemaking is
grounded in the unity of singularity as a natural self dividing into
multiplicity rather than aggregates of data imitating the 3p functions
of a self.




  UDA explains
  why the contrary occurs, through the first person indeterminacy
  bearing on a very huge and complex arithmetical reality.

  Why does hugeness, complexity, first person, or indeterminacy affect
  whether something is digital or not?

  Because there is a continuum of computational histories
  (computations)
  going through your state in arithmetic, or in the UD.

  There are histories. OK. Why does that make them digital or not?

 I assume I am a machine. Then the first person notion are NOT
 machine, they are NOT digitalisable for the first person point of view.

Does that mean that the only justification for saying they are not
digital is because our experience is not digital and you assume that
machines are like us?




  The rest follows
  from the 1-indeterminacy and its invariance for the huge delays in
  the
  UD virtual reconstitutions. Ask more if this is unclear, but you are
  supposed to have study the UDA.

  Yes, I don't really get where 'delays' come from.

 This is explained already in step 2, and then in the fact that the
 Universal Dovetailer dovetails. It run all computations, but some are
 infinite, so it runs them little pieces by little pieces, and
 introduce vast and many delays in all computations.

I have a similar view but don't limit it to computation. The cosmos is
a process of nesting frames of experience, creating a concrete
interior semiotic medium of nested frequencies ('time') and an
abstract exterior semiotic medium of nested scales ('space'). The
process is computational, but what is being computed is sense and
motive.


  Does the UDA exist
  in 'time'? Is time an inevitable epi- of +, *, and n?

 I guess you mean the UD. UDA is for the 8 step UD *Argument*.
 Yes, comp makes all notions of time phenomenological, except the UD
 time steps, which are based on the successor relation s(x) = s(x) + 1.
 But physical time and subjective duration needs longer explanations,
 and are mainly indexical first person (plural, singular) notions.

Time then exists as a consequence of UD, not a primitive within which
UD computes and wouldn't have any 'delays'.


  Still not seeing
  a connection with whether something is digital or not.

 If we are digital, our experience bears on an infinite set of
 computations, and the result is not digital. I let you study a bit
 more the UDA.



Yeah, I don't understand. Does Super Mario's experience bear on an
infinite set of computations?


  Second, the first person impression of the machine might be (and is
  necessarily, once you accept Theaetetus' insight) a non
  digitalizable
  truth, from the machine point of view.

  Which of Theaetetus' insight do you mean?

  The definition of knowledge by true belief. Kp = Bp  p.

  I think I know what that is, but since Google shows nothing at all for

Bruno, I did not branch out into the 1st line of my 1st quote of your
sentence.
Not that 2^16 is 'a' number, but parallel gives the idea of identicity
(at least in main qualia) which are (both) human talk. (Of course that's
what we can do).
I am glad that you agreed with my (generalized!) remark.
Now: to your question:
 *  - Which logics? Classical logic? -*
Any one you may call 'logic(s?)' in today's HUMAN thinking.* *It is beyond
our capabilities to even imagine (more sophisticated) ways of thinking,
which does not mean an exclusion of such. I did not visualize a change in
logic, simply assumed the possibility of thinking differently (not
necessarily using OUR math terms). (Cf: Cohen-Stewart's Zarathustrans - a
fictional reference).

 *- we have to take our theories seriously, -*
Not in my agnosticism. In conventional sciences a 'theory' is taken
seriously upon assumptions based on other (accepted?) theories
(calculations?). To let your ideas wander and look for yes/no consequences
(within today's knowledge) is a game of creativity, not established
science. This is how I ended up with many of my patents. For the same
reason do I NOT call my 'Plenitude-story' of generating universes a *
NARRATIVE*, not a theory.

Yes, and I think Bruno's argument is to show that if consciousness is a kind of

does in the MW interpretation.  However, that doesn't /solve/ the problem it just makes 
two problems the same.  In Everett's MWI there is a problem saying what probabilities

Google on theaetetus.
Socrates asked to Theaetetus to define knowledge. Theatetus gives many definitions 
that Socrates critizes/refutes, each of them. One of them consists in defining knowledge 
by belief, in modern time the mental state, or the computational state of the belief 
and the knowledge is the same, and a belief becomes a knowledge only when it is 
(whatever the reason or absence of reason) true. Another one is the justified true 
belief, which is the one which you can translate in arithmetic with Gödel's predicate. 
You can read Bp  p by I can justify p from my previous beliefs AND it is the case 
that p. To give you an example, if the snow was blue, a machine asserting snow is blue 
can be said to know that snow is blue. Indeed, the machine asserts the snow is blue, 
and it is the case that snow is blue (given the assumption).


The problem (for some) with that theory is that it entails that, when awake, we cannot 
know if we are dreaming or not, although in dream we can know that we are dreaming, the 
same for being not correct. It is not a problem for comp which makes that ignorance 
unavoidable.


For a machine that we know to be arithmetically correct, we know that Bp and Bp  p 
are equivalent. Yet, the machine cannot know that about herself, and the logic of Bp and 
of Bp  p are different. They obeys to the modal logics G and S4Grz, but I guess you 
need to read some book or some web pages to see what I mean here.


I find your explications of knowledge to be confusing.  You refer to Theaetetus who said 
knowledge = true belief.  But in your modal logic formulation B stands for either provable 
or proven (Beweisbar).  Provable and believed are too very different things.  I think 
that knowledge consists of a belief that is both true and causally connected to the thing 
believed (c.f. Gettier's paradox).   Of course belief that is held because the proposition 
is proven from some axioms does have a causal connection to the axioms.  But that is more 
than just believed.  The problem then arises when you say things like, We know there 
are true but unprovable facts about arithmetic.  We only 'know' those things in different 
meta-system where they do have a causal connection to other axioms we hypothesize as 
true.  But ultimately we cannot 'know' that axioms are true - as you say we just bet on them.

 Which assumption?

Your assumption that if a identical copy of you is made everything  
may seen identical to a third party but to itself, to the copy and  
the original, they would somehow have different viewpoints even if  
everything they saw was the same and they remained identical.


I don't make that assumption.





I think that is just plain wrong.


Like Brent told you, I agree with you.




Lately you seem to be equivocating somewhat on this point and  
everybody has a right to change their mind, but if you do then  
you'll have to rewrite your proof from page 1 because that  
assumption was important.


I never made that assumption. It is in your imagination. You really  
look like you want to see something invalid in the reasoning, and then  
you imagine assertion which does not exist (or show me where).






 Those admit precise and simple definition, related to the  
duplication and multiplication thought experience.

First person = content of a diary bring in the duplication devices.

OK, but the original and the copy will both write in their diaries  
I walked into the duplicating chamber, the machine was turned on  
and a copy of me appeared right in front of me face to face,


You are still avoiding the WM duplication. You cannot invalidate an  
argument by changing the premise.




the copy and the original agree on what occurred, so according to  
you the first person perspective, the one that both you and I  
believe is most important, is identical; so there is only one  
perspective, one consciousness.


Sure. This does not invalidate the point I am making. It does not  
address the point at all.





 Third person = content of a diary of an external observers.

OK, but the third person observer will write in his diary the  
original walked into the duplicating chamber, the machine was turned  
on and a copy of him appeared right in front of him face to face,  
the third person agrees on what happened with the first person, he  
agrees with both the copy and the original.


Please come back to the reasoning.





 First person plural = content of the diaries of a collection of  
person duplicated together.


I don't see the point of this one because according to you (and me  
too) if the viewpoint is identical then the consciousness of all of  
them is identical, so the word plural serves no purpose and just  
creates confusion.


Come back to the reasoning.





but you can't give a scrap of evidence that such differences  
actually exist,


Just look at the content of the diaries.

I did, if they say the same thing then their consciousness is  
identical from their viewpoint and my viewpoint and your viewpoint  
and the Easter Bunny's viewpoint and ANY viewpoint; and if the  
diaries are different then they are different people from ANY  
viewpoint.


Come back to the reasoning. In the thought experiment I am using, the  
content of the diaries are equal up to some pages, and then they  
diverge. The experiencer tries to predict which branch they will live.






 It contains statements like I predict that I will feel to be in W  
or in M, I am in M, so I win, pr I predict that I will see Flying  
circus, but I see nothing recognizable, so I fail, etc.

You come back again on this !?!
No, the point is not to establish what is meant by I. David, Quentin  
and others (including myself) have already explain this to you.
You continue to avoid the points. Follow the reasoning and you will  
see the purpose.





then it's like pushing on a string, you're doing it backwards,  
you've got to do it from the present to the past not from the  
present to the future. Looking back the Washington man remembers  
being the Helsinki man so they both are part of the same I, and the  
Moscow man remembers being the Helsinki man so they both are part of  
the same I, but the Moscow man does not remember being the  
Washington man so they are not part of the same I.


Which is part of the explanation of the first person indeterminacy.  
Good.





 If the guy annihilated die, then he would say that P(M) = P(W) =  
1/2, and there would be no 1-indeterminacy.


Of course here I made a typo mistake (which you missed). Read P(W) =  
P(M) = 0, in case the guy dies. But as we both agree on comp, the guy  
does not die in that process.




First of all you seem to make a distinction between dying and being  
annihilated that I do not understand, and second, if either of those  
things had happened to you you wouldn't be making any predictions,  
you wouldn't be saying anything at all.

  If there is a machine

  model at all (although modeling is certainly part of it). Our
  experience is not a total experience of THE universe, but it is a
  total experience of OUR world (perceptual inertial framework), which
  includes the understanding that there is a difference and the tools to
  actually extend our world further into rest of the universe.

  The machine's world is not similarly open to expansion. It does not
  have the tools to extend its sense. You could connect a camera to Deep
  Blue through a printer port in it would never in a trillion years
  figure out how to use it.

  I have a digital CD playing on a digital receiver. The acoustic
  drivers are digital too. The music is not digital.
  Another unsupported assertion. How would you know?
  If music were digital you wouldn't need to hear it. You could look at
  a picture of the data and get the same experience.

  Some people claimed that digital audio
  sounded different - but double blind tests showed they were mistaken.
  That may be true, and that's not what I was talking about, but also I
  don't think that any kind of objective test like that prove that
  anyone is 'mistaken' about how something feels. It may be that doing a
  double blind test creates a placebo effect when subjectivity is being
  tested.

 And it might be you're blowing smoke because you don't like the facts.

Possible, but it's also because in my understanding, subjectivity
works in exactly that way.










  Just as the double slit test does unexpected things to light,
  we cannot assume that our subtle awareness can be manipulated on
  demand. That assumption itself is a cognitive bias which may very well
  contaminate the data.

  It seems to me that digital audio is colder, clearer, with more
  brittle and shallow percussion and more sibilance than analog. It's
  hard to say because I'm not comparing apples to apples, but I'm not
  sure that the experiment you are talking about did either. I don't
  know what assumptions they made. Also why does everyone seem to make
  the same exact mistake about how digital sounds to them? Why no people

Hi John,

Did you note that nowhere was it mentioned in Bruno's comment that 
the 2^16 unverses had an upper limit of the time that it would take to 
perform the implementation! This is the escape clause for his claim. 
What is interesting about this multiple parallel universe idea is that 
it seems to me that we could make the time and qubit limit of any _one_ 
typical universe could be made arbitrarily small by putting a large 
quantum computer on a very fast star-ship and travelling at velocities 
that approach c. Since the Q-computer on the Enterprise would have an 
arbitrarily long time to implement its side of the Qubit's unitary 
evolution as some from an observer that is watchign the Enterprise on 
its long range scanners. The neat thing is that for Spock the 
computation would output its answer in no time at all IF and Only IF it 
was able to remain coupled to all those other parallel universes.
This scenario, set on the bridge of the Starship Enterprise, seems 
likely until you look into what acceleration does to quantum 
entanglement.it is well known that any acceleration spoils entanglement 
in an interesting way.


I apologize for my wandering off topic but I strange idea occurred

2012-03-23 Thread Quentin Anciaux
From a 3rd POV, there is no indeterminacy, we know there will be two you
after the duplication.

From your 1st POV, even if you know it, you'll (both you) still feel
singular, and the you who was asked before the experience what he expect to
feel after the duplication was unable to predict which one of the WM guy it
will be, yet each one is only one.

If MWI is true, that happens every time the you/environment differentiates.
So while you insist it is gibberish to ask the guy before the experience
what he will feel, then in that condition every time you ask a question
about a future event about yourself, it is gibberish.

You keep asking who is this you... it is the usual you, as the one you
use in your everyday gibberish question about yourself if MWI is true.

Dear Joseph,

How do numbers implement that necessary capacity to
define each other and themselves? What kind of relational
structure is necessary? From what I can tell, it looks like a
net of Indra where every jewel, here a number, reflects all
others. This is a non-well founded structure.


You'll have to be more explicit than this if I am to make any
sense of it.


Dear Joseph,

I first must say that I appreciate very much this exchange as
it forces me to better refine my wordings and explanations. In the
passage above I was trying to get at something that I see in the
implied structure of numbers, given Bruno's amazing ideas.
Remember, I think in pictures, so the relations between numbers
- with their Goedelizations and Loeb references - is to me a
network where any one entity - here an integer - is defined by and
related to all others. It looks like the structure of an infinite
Webster Dictionary!  What I also see is that the links are not
of a constant length - some connections between numbers are tiny -
like the link between prime pairs - while others are infinitely
long. What I am trying to point out is that this structure, is
very much_unlike_ the structure that we think of when we just
consider the number line where such a line is made up only of
integers - 0, 1, 2, 3, ...


This is all nice, but I can't understand it unless you give make this 
more formal/precise.


Do you only think in words? I'm just curious... I will try harder 
to sketch the idea in words for you.


Think of how Goedelizations and Goedel numbers work as a visual 
picture, perhaps as a poitrait by Matisse or Dali. We have a string of 
numbers that represents another set of numbers *and* some arithmetic 
operation on those numbers. Any such Goedel number is thus the 
equivalent to a handle on the space of numbers (which is, by 
definition, a one dimensional manifold 
http://en.wikipedia.org/wiki/Curve#Topology, also see 1 
http://en.wikipedia.org/wiki/Evenly_spaced_integer_topology and 2 
http://en.wikipedia.org/wiki/Open_sets#Topological_spaces), therefore 
if it is possible to have an infinity of goedel numbers in the integers 
then the resulting manifold would an infinity of handles (disjoint 
manifolds) on it. How many unique paths would exist on such a manifold? 
What is the average length of a path? (Please recall the fact that a 
handle can have any size iff it is simply connected and analytic) There 
is no such an average for the only faithful sample of the set of 
possible lengths of paths is the set itself (infinite sets are 
isomorphic to any of their proper subsets).
Remember that we can also have goedel numbers operating on (mapping 
into) dovetailed strings of goedel numbers and goedel numbers can have 
arbitrarily long number string lengths.. This makes the dimension of 
this manifold to be infinite because of the disjointness of the 
handles that are induced by the Goedelizing, thus making it (modulo 
the requirements of spaces to exist) an infinite space. It is only if 
the requirements of a space 
http://en.wikipedia.org/wiki/Space_%28mathematics%29 not being met 
that this would not occur. Given that a geodelization introduces 
arithmetic into the set of numbers then is automatically qualifies a 
goedelized number line to be the dual of a space (via the Stone 
representation theorem 
http://en.wikipedia.org/wiki/Stone_representation_theorem).


QED.

The visual mode and the symbol mode of languages seem to have a 
strange conjugacy




Numbers as Bruno is considering them, I contend, has a
structure that mathematicians denote as non-well founded in the
sense that there is no basic building block out of which this
structure is constructed unless we force it into a very tight
straight jacket. One example of just a constraint occurs when we
think of numbers as von Neumann numerals
http://bmanolov.free.fr/von-neumann-integer.php or something
like: s, s(), s(()), s((())), ... - where s is the null set which
we can define in terms of Spencer-Brown's laws of form as the
Double Cross (see

http://upload.wikimedia.org/wikipedia/commons/f/ff/Laws_of_Form_-_double_cross.gif),
my point being that we only obtain a 'well-founded' version when
we impose a constraint of the natural' structure.


Well, of course. To talk about well-foundedness you need a class and a 
relation, not just a class. It doesn't make sense to say numbers are 
non-wellfounded.


They are non-well founded if they are

I think the opposite is true: it's a bizarre and unjustified belief to

Dear Joseph,

Let us reason a bit about this belief. I think that it is very much 
justified simply because if one cannot name an object then statements 
about its truth or existence cannot be communicated. If a true statement 
about something cannot be communicated, is it really a truth? I assume, 
perhaps wrongly, that if an object can be named than it is, by 
definition, a particular. Therefore, by Bpp - p,  believing in a 
statement and that statement is true obliges me to only believe in 
particulars. Now your comment might be restated as it is bizarre and 
unjustified to think that existence (or there is nothing more) is 
nothing more than that which can be named. Would you still believe the 
statement? I am merely trying to be consistent with Bruno's thesis.




snip



You refer to Pratt's work. It seems like an interesting
metaphor, but I don't see how it solves the problem. Could
you be more explicit? The rational mechanics paper takes,
IMO, some odd and unjustified leaps when it comes to his
definitions. (An example: he says that the categories SET
and SET^OP represent respectively the physical and the
mental. How???)


Did you read the entire paper? He does explain this on
page 4 for example using functions and antifunctions... The
key is to not think of bodies and minds as things but as
processes. Pratt is considering a process dualism, not a
substance dualism as he points out that the notion of
substance is the fatal flaw of Descartes' program. I was
originally looking at Leibniz' Monadology in my study of the
mind body problem and found a similar solution, but such
required a rehabilitation of Leibniz' pre-established
harmony concept. (Basically, we would replace his idea of a
global fiat regime of synchronizations between the monads
with a ongoing process idea using concepts from quantum
game theory. I have found similar ideas in the work of Lee
Smolin, Stuart Kaufmann

http://www.amazon.com/At-Home-Universe-Self-Organization-Complexity/dp/0195111303/ref=sr_1_1?s=booksie=UTF8qid=1332256837sr=1-1
and David Deutsch. But that is not sufficient to make it
true. It is just a crazy idea at this point.)


Yes, I understand what the constructs are, and I see how Pratt
is making an interesting analogy, but I don't see the
justification for his conclusions about the mind-body problem.
But I haven't finished grokking the article.


It took me close to 6 years of autodidactic study to make
sense of Pratt's work and I must say that reading the other
papers on theChu Guide http://chu.stanford.edu/guide.html
helped a lot. I know that it is too much to ask for you to invest
this much effort into an idea that is by my admission crazy but
I invite you to anyway.


Thanks for the link; I'll continue looking into it.

Second, the first person impression of the machine might be (and is

What might help you is the idea that with comp, contrary to the  
(contradictory) belief that consciousness is a natural product of some  
physical activity, consciousness is an atemporal global feature of the  
arithmetical truth. Machine does not produce consciousness, they  
borrow it to the truth. With comp, there is a sense to say that only  
God is conscious, but to manifest itself relatively to machines, he  
has to be amnesic to who he is. Nature invented the brain, not to make  
machines conscious, but to make them amnesic to their true identity.  
If not, the prey would not mind escaping the predator, and life could  
not evolve.





They don't need to dream. But they can (trivially with comp that I
assume all the time). Physics appears because deep linear dreams are
shared by relatively persistent universal numbers.


Couldn't physics still theoretically appear without anything dreaming
anything? Isn't that the point of physics, to explain the world as a
structured relation which makes sense entirely in physical terms?


That's is very natural to believe. Somehow we are programmed to  
believe this. But it is false in the comp theory, as the UDA

explains, and as most mystics seems to grasp from introspection.
Note that this makes also possible to explain the physical in a non  
circular way, that is without assuming the physical.
This is counter-intuitive, and has to be counter-intuitive. We are not  
programmed to believe this, quite the contrary, as suggested by the  
above remark.










and if we have dreams we don't need numbers.



?



If our lives are being dreamed by Platonic universal principles, why
do we want to turn them into dust by seeking out the dreamers?


Because we are curious.


In Comp that can make sense that we would be curious about what can
only reveal our own lives meaningless data. In a sense realism, we are
only likely to be curious because on some level we already know that
comp is just another new dimension of meaning to explore and create
in. We know, on some level, that we don't really have to worry about
computers coming to life or developing feelings.


There is nothing to worry indeed. About machines coming to

I don't think Bruno disagreed with this.  I know I didn't.  The one consciousness only 
becomes two when there is something different - in the perception of the outside 
(Washington vs Moscow) or some random internal change.  Your thought experiment shows that 
comp implies that persons bodies can be duplicated without duplicating their consciousness 
(at least for a moment or two).  But as I said I don't see that this invalidates Bruno's

personal identity.

Even if our own world were nothing but a digital simulation, the

need any digital data to function?

Your comment brings up another related point. As you say, we only see

We can make inferences that extend beyond the literal capacities of

  Comp is not digital physics.

  How does a digital artificial intelligence make sense of it's world
  without converting or sampling every truth about that world available
  to it into digital?

 First, the fact that the digital machine converts truth about the
 world into digital, does not make that world digital.

Which world, the one being converted or the one that has been
converted?

 UDA explains
 why the contrary occurs, through the first person indeterminacy
 bearing on a very huge and complex arithmetical reality.

Why does hugeness, complexity, first person, or indeterminacy affect
whether something is digital or not?

 Second, the first person impression of the machine might be (and is
 necessarily, once you accept Theaetetus' insight) a non digitalizable
 truth, from the machine point of view.

Which of Theaetetus' insight do you mean?

To me speculating that a machine has a first person impression is just
a way to plug the problem. Since subjectivity doesn't make sense
mechanically or digitally, we'll say it's non digital and hang a
Mission Accomplished sign. It takes advantage of the privacy and
ineffability of subjectivity to misrepresent its absence as possible
presence, even though our experience with machines thus far has not
supported any presence at all.

 That is actually the case,
 because the impression of the machine is a conjunct of both a
 digitalizable belief and (some) truth, with the greek's suggested
 notion of knowledge.

beliefs, truths, knowledge...these are abstractions to me. Tertiary
level commentaries on experience which barely exist. Important, sure,
but lacking in any power to initiate direct action. Which is maybe why
a machine has no such power.




  If you negate this, it means that
  you assume the level to be infinitely low,

  No, it means I understand that your assumption that description
  can be
  quantified is simplistic and inaccurate.

  Description of my (generalized) brain. With your theory we have
  zombie.

  Never zombie, only puppet. Zombie is like calling water 'wet fire'.

 I don't think so. With the Heisenberg Matrix of the Milky way, no-one
 would be able to distinguish me or you from the behavior of the entity
 simulated. If comp is false, those entity who behaves exactly like
 you or me, are not conscious, and so they are by definition p-zombie.

The word zombie privileges the expectation of consciousness, while the
word puppet does not. The fact that the Heisenberg Matrix of the Milky
way fails completely in detecting consciousness does not mean that the
simulations it takes for genuine are missing something that they
should have.

That they are simulations in the first place means that we intend them
to resemble something that they are not. I make a witch's head out of
a shrunken apple - that is a simulation of a witch; a puppet of a
witch. It isn't an actual witch that has been rendered a zombie. It
freaks me out that I keep having to explain this, it seems stunningly
obvious to me. I draw a dog on a paper bag, is it now a dog zombie?

The deeper insight here of course is that simulation relates only to
the intended audience. It looks like a witch or a dog only to us. It's
a text. It's symbols are not grounded in the firmament of the cosmos
like matter or biology, they are only suggestions that help 'us'
fabricate a fictional association for ourselves.




  Study the sane04 paper.  Or search in the archive. It is a
  consequence
  of comp that physics emerge from the way numbers can bet on
  arithmetical relations. It is not entirely obvious.

  I don't have a problem with physics emerging from comp, I have a
  problem with consciousness emerging from either one.

 I understand.
 This is related with the fact that we can explain why consciousness is
 not entirely explainable by the machine.
 The machine also find hard to believe that consciousness emerge from
 arithmetical truth. But she cannot accept this because she can
 understand the necessary transcendent aspect of any notion of truth
 encompassing the truth about herself.

It sounds like you mean that machines can tell what is true about
themselves so they can't accept that there is an external source of
all truth. That makes a little sense, but I have no problem

spectrum.  Of
course Bruno's theory is that it's all digital, but we're within the digits and

capture more than a measure zero.

Yes, human beings can't detect everything either, but my point was
that we know for certain that everything in an AI's world has to be
modeled digitally, therefore a digital brain creates a digital world
within it.

I'm not sure that's so.  All of our physical models of the world are based on 
continua.
Continua can be described and reasoned about by a digital system and continuous 
models can
be computed to arbitrarily high precision (which is what we actually do in 
science and
engineering).

That's because the world that they are modeling is actually not
digital,


Unsupported assertion.


but the model itself still is.


No. So far as I know, no one has come up with a digital model of physics that isn't 
empirically falsified - and it isn't for want of trying.  All the models are continuous 
and based on real numbers.  It is just that all the calculations and measurements are 
digital, i.e. based on integers.



If there is a machine
intelligence in there, we know that it must live in the world that we
give it to sample digitally, whether or not it can produce output
which we interpret non-digitally. It's back to symbol grounding again.


What difference does it make to symbolic grounding whether the symbol refers to a 
continuum or an integer field?



I have a digital CD playing on a digital receiver. The acoustic
drivers are digital too. The music is not digital.


Another unsupported assertion. How would you know?  Some people claimed that digital audio 
sounded different - but double blind tests showed they were mistaken.



The CD, the
receiver, and the speakers cannot hear the music. We can safely reason
that they probably do not hear the music, yes? We can assume though
that they must sample the CD digitally though. That we know for a
fact. That's all we know for a fact. If the same were true of us, we
would have no real reason to listen to a sequence of digital codes,
but if we did there would be no reason for it to sound like anything
other than a sequence of digital codes. It should sound just like it
tastes.


Just because our ability to sense the world is not
unlimited doesn't mean that our sense is digital or a model. Our
experience of the world may not be a model at all, but a direct
presentation at the anthropomorphic level (which includes, but is not
limited to a mixture of lower level analog and digital
representations).
Even if our own world were nothing but a digital simulation, the
experience of it is not digital,

You don't know that.  How would continua experience differ from digital 
experience?

It's not about being able to tell the difference, it's the fact that
there is any sensory experience at all. Any kind of sensory experience
is redundant if you have a digital information transfer. It would be
functionally useless and physically implausible to the extreme.


LOL!!  That's pretty funny coming from a guy reading pixels off a screen that looks 
continuous to him.

digital world. Why create

Are you asking why God did something?

God, Chief Engineer, evolution, logic, whatever.  Why does it make
sense that sense exists if you don't functionally need it?


That would be a good question IF I had created it for me.




a floridly rich abstraction layer of sense
experience if you already have the data you need to function
optimally, or, if you have the sense experience already, why would you
need any digital data to function?
Your comment brings up another related point. As you say, we only see
a small sliver of the EM spectrum. What that means is that we
(figuratively) 'see' that we don't literally 'see' all that there is.
We can make inferences that extend beyond the literal capacities of
our direct sensation. Can machines do that?

Sure. Machines have extended sensory ability so, for example, they can navigate 
by GPS
signals which we can't even detect.

Ugh. Not extended beyond *our* sensory abiility... extended beyond
*their own* sensory ability. We can't see gamma rays, but we figured
out that they (sort of) exist. Do Geiger counters ever figure out that
they are missing the visible spectrum?


Similarly, migratory birds can navigate by sensing
the Earth's magnetic field - something we do via prosthetics like compasses.

Yes. I know.


Can machines figure out
that they lack emotion on their own?

If they were sufficiently intelligent.

That is the assumption I'm challenging.

False. The exact contrary has been proved.



My point though, is that by
assuming that things can be truly, ontologically digitized (and not
merely imitated to the perceptual satisfaction of a given audience),
comp already fails to recognize the use-mention distinction (http://
en.wikipedia.org/wiki/Use–mention_distinction) of consciousness.

Assuming that we can survive with a digitized body is only the tip of
the iceberg of assumptions about pattern that take pattern recognition
utterly for granted.


We don't need to take for granted any mental ability. Just the  
existence of a level of description. If you negate this, it means that  
you assume the level to be infinitely low, so that you need to  
introduce actual infinity and non computability of all levels. It is  
your right, but you fail to present a theory of this.





Comp exports inorganic naive realism to a
universal level and builds from there.






In particular it does
answer the question where does the universe come from?. The  
answer
is, by the truth about addition and multiplication, and the

details are accessible to any universal machines.
You will ask: where does addition and multiplication comes from.
This, in the comp theory can be answered: we will never know, at
least
in any publicly communicable way.



Why add the extra step of addition and multiplication?


To get a Turing complete ontology.


What does it further us though to have a Turing complete ontology
relate to the question in the first place? Instead of trying to make
it answer 'where does the universe come from?', why not 'where does
computing come from'?


Because it is provable that computing exists once the addition and

A bell's not a bell 'til you ring it, A song's not a song 'til you

This is the symbol grounding problem, the use-mention distinction, the
Chinese Room, the China Brain, Leibniz windmill, etc. It's an
interesting problem in that degree to which the problem exists depends
upon where you are looking at it from. In 3p, there is no reason to
make such a distinction. Since the program has to define a bell as
ringable or a song as singable in advance, there is no way to 'show'
the difference. In 1p, the perspective is exactly flipped. The
continuous discovery and participation in the 'show' is everything.
The assumption of Comp cannot be made without flattening 1p to a 3p
shadow. It is a toy model of 1p but has no sense of presentation, only
an black box where numbers dream (of things besides numbers,

such a enormous change (that is nevertheless undetectable by the scientific
method) has occurred, you just ask us to believe that it has. You don't
claim that one hydrogen atom is different from another and I'm sure you
will grant that information can be duplicated, and yet when information and
generic atoms get together and form another identical body and brain of
Bruno Marchal then for reasons you never explain you say you've got to
start differentiating between different views and start talking about
1p,2p,3p'. And through all this science can find no difference to make a
differentiation between. I'm sorry Bruno but I just can't get past that.

For example: If the body and brain of the Helsinki man is annihilated a
instant after the information in his body and brain was read out and used
to make identical copies in Washington and Moscow then you say the Helsinki
man is dead. But I don't understand why you say that, there is certainly
someone (actually in this example 2 people) who would very very strongly
disagree with you about him being dead because he remembers being the
Helsinki man and remembers walking into the duplication chamber just
seconds ago, and he has no gaps or jumps or discontinuity of any sort in
his subjective experience. He remembers walking out of the chamber only to
find himself in a distant city, and now you tell him he's dead. He wouldn't
believe you and neither would I. I just don't see what more the Helsinki
man needs to do to survive, he's survived from his own point of view and
after all that's the only one that matters.

 I don't assume physics.


That doesn't sound good.

we are neutral on the natire of matter.


Nor that. And if you're not a big fan of matter I don't understand why it's
so significant to you that the atoms in the Helsinki man's body have been
rearranged into ashes, especially when there are 2 perfectly good identical
replacement bodies available that were made of atoms that were just as good
as the atoms the have in Helsinki and arranged in exactly the same way .

Stephen, I am starting to think that you have fundamentally misunderstood
the UDA. You have repeatedly voiced this misconception, that COMP implies
that the physical world does not exist. It exists, but it is not
fundamental. It is still phenomenal.

I will respond to your other message shortly, and discuss the issue of
communicability and the need for physical instantiation a little more.








 which is exactly what we are claiming when we say that ... our
 generalized brains  ... are this and that, such as what is implied by
 ...the latter is just a restatement of the former. The point is that we
 first need to dig a bit deeper and establish by natural mathematical means
 that 1) digital substitution is a sound mathematical concept and 2) that it
 is possible.


 1) Yes, thanks to the notion of level, digital substitution is well
 defined, and sound (if the level is correctly chosen).


 Yes, and this makes it local not global and thus is not consistent
 with a representation in Platonic terms.


  UDA shows the passage from local to global. Why and how it occurs. You
 lost me.


 Could you be more specific? Are you thinking of UDA3? But is this
 global plurality not collapsed in UDA4 and UDA5? Let me be clear about what
 I am thinking with regards to the words local and global. By Global I
 mean pertaining to all of a collection of many from any kind of
 partitioning on the collection. By local I mean pertaining to a
 collection from only one partitioning of the collection. For example, in
 physics, an effect is global if it is invariant to shifts from one point of
 view to another, the potential of the electromagnetic field is a good
 example. In physics, an effect is local if it vanishes when one shifts to a
 different point of view.




 2) That it is (in principle) possible *is* the comp assumption.


 OK, but you are assuming more. You are assuming that computations have
 particular and definite properties merely because they are true,


  true does not apply to computations, but to proposition.


 This does not change the implication of what I wrote. You are still
 thinking that mere existence defines properties. My claim is that this is
 ontologically and epistemologically incoherent as it implies that the
 difference of the properties that one object X has from the properties that
 another object Y has follows merely from the existence of X and Y. How does
 the mere existence of X and Y require that X and Y are different at all?





  you are claiming implicitly that properties supervene on the soundness
 of the object having such properties.



  sound applies to theories, not to object.


 OK. So we say that if there is a sound theory of an object then the
 object must exist? I am just trying to be sure I understand.




  This is, I claim, equivalent to postulating the existence of a Universal
 Observer that can somehow percieve all UTM strings and define by fiat which
 are equivalent to which


  You miss the 1-indeterminacy here. We don't need to know which
 computations are equivalent or not, because we live them.


 No, I was considering how you assume that properties follow from mere
 existence. You are thinking of theories as constructions to define the
 existence of an object, say a computation, and then forgetting that you
 constructed the theory that implied the properties of the object so that
 you can claim look it exists and has properties completely independent of
 me. This is just the logical conclusion of thinking that computations are
 independent of the necessity of any physical implementation. This is one
 piece of your thinking that upsets me, you are taking the universality
 concept too far.




  without having to actually implement all of them


  by step 8.


 Again, just because a computation does not require a particular
 physical implementation does not make it independent of the need for at
 least one implementation. To claim the contrary is equivalent to talking
 about things that you cannot even indirectly name or describe. You have
 effectively severed all possibility of contact between the Platonic realm
