I don't understand the question.  What parallel experiences do  
you refer to?  And you're asking why they disappeared?


The question is how does Fuchs prevent a superposition to be  
contagious on the observer


I think he takes an instrumentalist view of the wave function - so  
superpositions are just something that happens in the mathematics.


But then I don't see how this could fit with even just the one  
photon interference in the two slits experiment.


?? The math predicts probabilities of events, including where a  
single photon will land in a Young's slit experiment - no  
superposition of observer required.



But it illustrates that superposition is physical/real, not purely  
mathematical. Then linearity expands it to us.



















When I read Fuchs I thought this: Comp suggest a compromise:  
yes the quantum wave describes only psychological states, but  
they concern still a *many* dreams/worlds/physical-realities,  
including the many self-multiplication.


There is no many in Fuchs interpretation, there is only the  
personal subjective probabilities of contemplated futures.


I notice the plural of futures. Are those not many?


Sure, but they are contemplated, not reified.


OK. But apparently object of contemplation can interfere with the  
real, which is a bit weird to me.


The 'interference' is a calculational event 'between' possible  
futures.  Or even the result of considering all possible paths.


That leads to instrumentalism. That is dont ask, don't try to  
understand or get a bigger picture.











I know Fuchs criticize Everett, but I don't see how he makes the  
superposition disappearing. he only makes them psychological,  
which is not a problem for me. there are still many.



Yes, that's why I said I think his approach is consistent with  
yours.  I think Fuchs view of QM is similar to what William S.  
Cooper calls for at the end of his book The Evolution of Reason  
- a probabilistic extension of logic. This is essentially the view  
he defends at length in Interview with a Quantum Bayesian, arXiv: 
1207.2141v1


OK.













It is still Everett wave as seen from inside.

We just don't know if the dreams defined an unique  
(multiversal) physical reality. Neither in Everett +GR, nor in  
comp.


Bayesian epistemic view is no problem, but you have to define  
what is the knower, the observer, etc. If not, it falls into a  
cosmic form of solipsism, and it can generate some strong  
don't ask imperative.


You assume that if others are not explained they must be rejected.


I just ask for an explanation of the terms that they introduce.



I think he takes the observer as primitive and undefined (and I  
think you do the same).



What? Not at all. the observer is defined by its set of beliefs,  
itself define by a relative universal numbers.


Fuchs defines 'the observer' as the one who bets on the outcome of  
his actions.


Comp has a pretty well defined notion of observer, with its  
octalist points of view, and an whole theology including his  
physics, etc.








Physicists, like Fuchs, and unlike philosophers, are generally  
comfortable with not explaining everything.


Me too. but he has still to explain the terms that he is using.


What's your explanation for the existence of persons?  So far what  
I've heard is that it's an inside view of arithmetic - which I  
don't find very enlightening.


What do you miss in the UDA?


As I understand it the UD computes everything computable and it's  
only your inference that observers (and the rest of the multiverse)  
*must be in there somewhere* because you've assumed that everything  
is computable.



On the contrary: I assume only that my brain (or generalized brain) is  
computable, then I show that basically all the rest is not. In  
everything, or just in arithmetic, the computable is rare and  
exceptional.









Fuchs, correctly I think, says an 'interpretation'

That is simply wrong, and I don't see why you say that. But even if  
that was true, that would prove nothing.




and that paper and pencils are the preferred instruments?


Maybe I was premature in saying it was promissory...it would appears  
that there has not been any promise for it in quite some time.






It is almost applicable, but the hard part is that it is blind to  
its own blindness, so that the certainty offered by mathematics  
comes at a cost which mathematics has no choice but to deny  
completely. Because mathematics cannot lie,


G* proves []f

Even Peano Arithmetic can lie.
Mathematical theories (set of beliefs) can lie.

Only truth cannot lie, but nobody know the truth as such.

 Something that is a paradox or inconsistent is not the same thing  
as an intentional attempt to deceive. I'm not sure what 'G* proves  
[]f' means but I think it will mean the same thing to anyone who  
understands it, and not something different to the boss than it  
does to the neighbor.


Actually it will have as much meaning as there are correct machines  
(a lot), but the laws remains the same. Then adding the non- 
monotonical umbrella, saving the Lôbian machines from the constant  
mistakes and lies they do, provides different interpretation of []f,  
like


I dream,
I die,
I get mad,
I am in a cul-de-sac
I get wrong

etc.

It will depend on the intensional nuances in play.

Couldn't the machine output the same product as musical notes or  
colored pixels instead?


Why not. Humans can do that too.












it cannot intentionally tell the truth either, and no matter how  
sophisticated and self-referential a logic it is based on, it can  
never transcend its own alienation from feeling, physics, and  
authenticity.


That is correct, but again, that is justifiable by all correct  
sufficiently rich machines.


Not sure I understand. Are you saying that we, as rich machines,  
cannot intentionally lie or tell the truth either?


No, I am saying that all correct machines can eventually justify  
that if they are correct they can't  express it, and if they are  
consistent, it will be consistent they are wrong. So it means they  
can eventually exploits the false locally. Team of universal numbers  
get entangled in very subtle prisoner dilemma.

Universal machines can lie, and can crash.

That sounds like they can lie only when they calculate that they  
must, not that they can lie intentionally because they enjoy it or  
out of sadism.


That sounds like an opportunistic inference.

  Ok, so you then also have to agree that John Clark 1 second ago is not
  identical to John Clark 2 seconds ago


 Yes.

  But things would get a bit confusing if I started calling you Mary Sue
  now.


 Yes.


  Both you and external observers agree that you are still John Clark.


 Yes.

  Either you claim that teleportation is fundamentally different from time

 Yes.

 I do.

 No, your prediction failed.

There goes my daily dose of dopamine. Will have to find some other way
to get it...

 I think the 2 things are fundamentally different
 because the John Clark of one second ago and the John Clark of right now
 will never meet,

Alright, but this again leaves us at a crossroad:

1) You believe that teleportation is fundamentally impossible, so this
type of thought experiment is based on an absurd premise;

2) You believe that teleportation is possible, in which case you
accept the thought experiment and are confronted with the question of
what you would perceive if you went through such an experience.

I don't feel I am sufficiently knowledge in physics to have and
educated opinion on teleportation. I'm pretty sure you have a much
more sophisticated knowledge of physics than I do, so I'm more than
happy to listen to your arguments. Not going to make any more
prediction on what you might think because my dopamine is already low.

On the next point you will see why I wasn't paying attention in physics class.

 so there is no confusion and separate names are not needed
 to avoid confusion and pronouns cause no trouble. But with duplicating
 chambers the 2 John Clarks could meet and stand right next to each other,
 and if you were to say I like John Clark but I don't like John Clark your
 meaning might be clear in your mind but you would need to change your
 language if you wanted to communicate the idea to others.

I had a very unpleasant physics teacher (coincidently... :) ) who
appeared to wear the same trousers throughout the entire semester. A
scientifically-minded colleague of mind decided to throw some ink at
her ass. It turns out that she, indeed, wore the same trousers for the
entire semester. How do you feel about tattoos?

 And the place to
 start would be to be careful with pronouns and give one of the John Clarks,
 it doesn't matter which one, the nickname Mary Sue.

http://1.bp.blogspot.com/_OW6wa7cAFBY/TPACSytH_kI/AvQ/BmLVAQA/s1600/mary_sue.jpg

 True, John Clark might
 not like it, but a lot of people don't like their nickname.


  I also predict an attempt to avoid answering the question directly


 That prediction has also failed but you still feel like Telmo Menezes
 because predictions, right or wrong, have nothing to do with identity;

I don't think I claimed predictions had anything to do with identity.

 you
 feel like Telmo Menezes because you remember being Telmo Menezes yesterday
 and for no other reason.

Yes.

 Energy and matter (and the universe whatever it is), is composed by the
 sum of the infinity of computations going through your state as it is
 defined by an infinity of computations (and not one), it is not computed.

 A piece of matter (or you fwiw) below the substitution level is an
 infinity of computations.

 Quentin



No I'm saying, that matter/you is not *a* computation, but the infinite set
of computations going through your current state (at every state, an
infinity of computations diverge, but there is still an infinity going
through that state and it's for every state).

Quentin



 You seem to be saying that the infinity of computations are not computed.
 That does not make sense.

 The 'interference' is a calculational event 'between' possible futures.

 Yes, that's why I said I think his approach is consistent with yours.  I
 think Fuchs view of QM is similar to what William S. Cooper calls for at

 I think Craig would say he does think computers (and many/all other 
 things) do experience something,


 You're half right. I would say:

 1. All experiences correspond to some natural thing.
 2. Not all things are natural things. Bugs Bunny has no independent 
 experience, and neither does Pinocchio. 
 3. Computers are made of natural things but, like all machines, are 
 ultimately assembled unnaturally.
 4. The natural things that machines are made of would have to be very 
 low level, i.e., not gears but the molecules that make up the gears.

 Unless a machine used living organisms, molecules would probably be the 
 only natural things which an experience would be associated with. They 
 don't know that they are part of a machine, but there is probably an 
 experience that corresponds to thermodynamic and electromagnetic 
 conditions. Experiences on that level may not be proprietary to any 
 particular molecule - it could be very exotic, who knows. Maybe every atom 
 of the same structure represents the same kind of experience on some 
 radically different time scale from ours. 

 It's not really important - the main thing is to see how there is no 
 substitute for experience and a machine which is assembled from unrelated 
 parts has no experience and cannot gain new experience in an alien context.

 I think that a machine (or any inanimate object or symbol) can also 
 serve as a vehicle for synchronicity. That's a completely different thing 
 because it is the super-personal, holistic end of the sensible spectrum, 
 not the sub-personal, granular end. The creepiness of a ventriloquist 
 dummy 
 is in our imagination, but that too is 'real' in an absolute sense. If 
 your 
 life takes you on a path which tempts you to believe that machines are 
 conscious, then the super-personal lensing of your life will stack the 
 deck 
 just enough to let you jump to those conclusions. It's what we would call 
 supernatural or coincidental, depending on which lens we use to define 
 it..

  just that it is necessarily different from what we experience. The 
 reason for this has something to do with our history as biological 
 organisms (according to his theory).


 Right, although not necessarily just biological history, it could be 
 chemical too. We may have branched off from anything that could be made 
 into a useful machine (servant to alien agendas) long before life on Earth.


 What if humanity left behind a nano-technology that eventually evolved 
 into mechanical organisms like dogs and fish, would they have animal like 
 experiences despite that they descended from unnatural things?


 The thing that makes sense to me is that the richness of sensation and 
 intention are inversely proportionate to the degree to which a phenomenon 
 can be controlled from the outside. If we put nano-tech extensions on some 
 living organism, then sure, the organism could learn how to use those 
 extensions and evolve a symbiotic post-biology. I don't think that project 
 would be controllable though. They would not be machines in the sense that 
 they would not necessarily be of service to those who created them. 



 Craig,

 Thanks for your answer.  That was not quite what I was asking though.  
 Let's say the nano-tech did not extend some living organism, but were some 
 entirely autonomous, entirely artificial  cell-like structures, which could 
 find and utilize energy sources in the environment and reproduce 
 themselves.  Let's say after millions (or billions) of years, these 
 self-replicating nanobots evolved into multi-cellular organisms like 
 animals we are familiar with today. Could they have experiences like other 
 biological creatures that have a biological lineage?

We assume the arithmetical truth. In particular we assume that all

false, independently of us.


From this we cannot prove that matter exists, or not, but we can  
prove that the average universal numbers will (correctly) believe in  
matter (but it will not know that it is correct).


So, if you have no problem in believing propositions like there is no  
biggest prime number are true independently of me and you, and the  
universe, then you can understand that the proposition asserting the  
existence of (infinitely many) computations in which you believe  
reading my current post, is also true independently of us.


The appearance of matter emerges from the FPI that the machines cannot

Arithmetical truth escapes largely the computable arithmetical truth

I guess you missed the step seven of the UDA, and are perhaps not

what any computer can generate or compute.


Then my, or your, mind is associated to *all* computations going  
through your actual state of mind, and below your substitution level  
there are infinitely many such computations. They all exist in  
arithmetic, and the FPI glues them, in a non computable way, in  
possible long and deep physical histories.

The only difference between first person and third person, used here,  
is that the first person memories (the content of the diaries), are  
annihilated and reconstituted together with the person's body.


In the arithmetical version, the first person is proved to be not  
directly amenable to the use of the dx = xx algorithm (an obvious  
cousin of the famous Mocking Bird combinators, btw), but, by a sort of  
miracle, thanks to Gödel's second incompleteness theorem, (using the  
Dx = xx algorithm at another level!), we can recover it with the  
Theaetetus definition of the knower, which recovers in the only way  
possible (a result proved by Artemov) a knower from the Gödel's notion  
of self-reference.


So, asking me to not use pronouns, in what is in great part a theory  
of pronouns, is like asking me to square the circle.
The eight arithmetical hypostases are eight precise mathematics of  
eight simple and deep machine's self-referential points of view, that  
is pronouns, like 1-I, 3-I, singular, plural, etc.


But in UDA, you don't need Gödel-Kleene, as the first person histories  
are defined in simple third person terms (sequences of W and M written  
in the personal diaries), and it is rather obvious that, with the  
protocols, all are 1-self non predictable, although some statistical  
distribution can be predicted.


Step 4 asks if those statistical distribution [of those first person  
experiences (diary content of the one who actually do the self  
multiplications)]  have to change if we introduce reconstitution  
delays in some branches of the self-multiplication changes ).


That's just step 2 + step 3. So it should be easy.

Bruno: Arithmetical truth escapes largely the computable arithmetical truth
(by Gödel).


Richard: I guess I am too much a physicist to believe that uncomputible
arithmetical truth can produce the physical.
Since you read my paper you know that I think computations in this universe
if holographic are limited to 10^120 bits (the Lloyd limit) which is very
far from infinity. I just do not believe in infinity. In other words, I
believe the largest prime number in this universe is less than 10^120. So I
will drop out of these discussions. My assumptions differ from yours.

 Energy and matter (and the universe whatever it is), is composed by the
 sum of the infinity of computations going through your state as it is
 defined by an infinity of computations (and not one), it is not computed.

 A piece of matter (or you fwiw) below the substitution level is an
 infinity of computations.

 Quentin



 No I'm saying, that matter/you is not *a* computation, but the infinite
 set of computations going through your current state (at every state, an
 infinity of computations diverge, but there is still an infinity going
 through that state and it's for every state).


 Yes. It generalizes what Everett did on the universal quantum wave, on the
 whole arithmetical truth (which contains the whole computer science
 theoretical truth). If QM is correct, the SWE is redundant, and a
 consequence of comp. Physics is one aspect of arithmetic seen by its
 internal creatures (the universal or not numbers). We can concretely
 extract physics from the interview of the chatty rich one (the Löbian
 numbers).

 You seem to be saying that the infinity of computations are not computed.

We assume the arithmetical truth. In particular we assume that all closed formula

(+1), + and *) are all either true or false, independently of us.


From this we cannot prove that matter exists, or not, but we can prove that the average 
universal numbers will (correctly) believe in matter (but it will not know that it is 
correct).


That's not at all clear to me.  A universal number encodes proofs - is that what you mean 
by it believes something?  But how is this something identified at 'matter'?




So, if you have no problem in believing propositions like there is no biggest prime 
number are true independently of me and you, and the universe, then you can understand 
that the proposition asserting the existence of (infinitely many) computations in which 
you believe reading my current post, is also true independently of us.


The appearance of matter emerges from the FPI that the machines cannot avoid in the 
arithmetical truth.


Arithmetical truth escapes largely the computable arithmetical truth (by Gödel).






And I thought the generalized brain did the computations,


Only the computations associated to your mind.


not that it was only computed. How does Bruno show that all the rest which presumably

I guess you missed the step seven of the UDA, and are perhaps not aware that 
arithmetical truth is incredibly big, *much* bigger than what any computer can generate 
or compute.


Then my, or your, mind is associated to *all* computations going through your actual 
state of mind,


That sounds like an uncomputable totality.

Brent

and below your substitution level there are infinitely many such computations. They all 
exist in arithmetic, and the FPI glues them, in a non computable way, in possible long 
and deep physical histories.

Karl Pribram: the holographic brain

2013-10-15 Thread Evgenii Rudnyi
I once have heard that Karl Pribram has a theory of a holographic brain 
and decided to read his latest book


Karl H Pribram, The Form Within: My Point of View.

Unfortunately I was unable to understand his theory, as for me the book 
was too eclectic. One quote that I like is below, but I have failed to 
understand how he has come exactly to such a conclusion based on 
neuroscience.


Does someone here know his theory? Is there somewhere a better 
description of his ideas as in his book?


Evgenii
--
http://blog.rudnyi.ru/tag/karl-h-pribram

p. 531-532 “Most important, ‘in ancient times’ we navigated our world 
and discovered experiences in ourselves that reflected what we observed 
in the world: We woke at sunrise and slept at sunset. We were intimately 
connected at every level with the cycles of nature. This process was 
disrupted by the Copernican revolution, by its aftermaths in biology – 
even by our explorations of quantum physics and cosmology – and in the 
resulting interpretations of our personal experiences. But today, once 
again, we have rediscovered that it is we who observe our cosmos and are 
aware that we observe; that it is we who observe our navigation of our 
world and observe our own observations.”

experience anything, in principle, given that people can, and

I think Craig would say he does think computers (and many/all other  
things) do experience something,


You're half right. I would say:

1. All experiences correspond to some natural thing.
2. Not all things are natural things. Bugs Bunny has no independent  
experience, and neither does Pinocchio.
3. Computers are made of natural things but, like all machines, are  
ultimately assembled unnaturally.
4. The natural things that machines are made of would have to be  
very low level, i.e., not gears but the molecules that make up the  
gears.


Unless a machine used living organisms, molecules would probably be  
the only natural things which an experience would be associated  
with. They don't know that they are part of a machine, but there is  
probably an experience that corresponds to thermodynamic and  
electromagnetic conditions. Experiences on that level may not be  
proprietary to any particular molecule - it could be very exotic,  
who knows. Maybe every atom of the same structure represents the  
same kind of experience on some radically different time scale from  
ours.


It's not really important - the main thing is to see how there is no  
substitute for experience and a machine which is assembled from  
unrelated parts has no experience and cannot gain new experience in  
an alien context.


I think that a machine (or any inanimate object or symbol) can also  
serve as a vehicle for synchronicity. That's a completely different  
thing because it is the super-personal, holistic end of the sensible  
spectrum, not the sub-personal, granular end. The creepiness of a  
ventriloquist dummy is in our imagination, but that too is 'real' in  
an absolute sense. If your life takes you on a path which tempts you  
to believe that machines are conscious, then the super-personal  
lensing of your life will stack the deck just enough to let you jump  
to those conclusions. It's what we would call supernatural or  
coincidental, depending on which lens we use to define it..  http://s33light.org/post/62173912616 
  (Don't you want to have a body?)


After reading this ( http://marshallbrain.com/discard1.htm ) I am  
not so sure...



just that it is necessarily different from what we experience. The  
reason for this has something to do with our history as biological  
organisms (according to his theory).


Right, although not necessarily just biological history, it could be  
chemical too. We may have branched off from anything that could be  
made into a useful machine (servant to alien agendas) long before  
life on Earth.



What if humanity left behind a nano-technology that eventually  
evolved into mechanical organisms like dogs and fish, would they  
have animal like experiences despite that they descended from  
unnatural things?


The thing that makes sense to me is that the richness of sensation  
and intention are inversely proportionate to the degree to which a  
phenomenon can be controlled from the outside. If we put nano-tech  
extensions on some living organism, then sure, the organism could  
learn how to use those extensions and evolve a symbiotic post- 
biology. I don't think that project would be controllable though.  
They would not be machines in the sense that they would not  
necessarily be of service to those who created them.



Craig,

Thanks for your answer.  That was not quite what I was asking  
though.  Let's say the nano-tech did not extend some living  
organism, but were some entirely autonomous, entirely artificial   
cell-like structures, which could find and utilize energy sources in  
the environment and reproduce themselves.  Let's say after millions  
(or billions) of years, these self-replicating nanobots evolved into  
multi-cellular organisms like animals we are familiar with today.  
Could they have experiences like other biological creatures that  
have a biological lineage? If not, why not?


No, I don't think that

Why would it occur naturally, when organic biology has done so, and
presumably used up all the food sources that might be available?

 3. a successful experiment to create life from basic molecules


Arguably the biosphere counts as this, presumably not an intentional
experiment.


 4. a machine which seems to feel, care, and have a unique and unrepeatable
 personal presence


Arguably a human being is one of these


 5. a mechanized process which produces artifacts that seem handmade and
 unique
 6. two separate bodies who are the same person
 7. an organism which reproduces by transforming its environment rather
 than reproducing by cell division


This seems to me to have gone completely off the point.


 8. an organism which emerges spontaneously from Boltzmann conditions in
 the environment rather than seeded inheritance


What?!? (He said billions of years, not googolplexes...!)


 9. an event or observation which leads us to conclude that gathering
 energy and reproduction are sufficient to constitute bio-quality awareness.

 I don't understand that sentence.

I may be missing something here but I believe the question is whether
machines can have experiences. Isn't a human being a machine that has
experiences?

 The thing that makes sense to me is that the richness of sensation and 
 intention are inversely proportionate to the degree to which a phenomenon 
 can be controlled from the outside. If we put nano-tech extensions on some 
 living organism, then sure, the organism could learn how to use those 
 extensions and evolve a symbiotic post-biology. I don't think that project 
 would be controllable though. They would not be machines in the sense that 
 they would not necessarily be of service to those who created them. 



 Craig,

 Thanks for your answer.  That was not quite what I was asking though.  
 Let's say the nano-tech did not extend some living organism, but were some 
 entirely autonomous, entirely artificial  cell-like structures, which could 
 find and utilize energy sources in the environment and reproduce 
 themselves.  Let's say after millions (or billions) of years, these 
 self-replicating nanobots evolved into multi-cellular organisms

 Excuse me for butting in, but I'm not sure what should means here. Are 
 you saying these things should *already* exist? But the original 
 suggestion was about future technology... Though I can't see what else you 
 could mean, though.


 1. a natural occurrence of inorganic biology


 Why would it occur naturally, when organic biology has done so, and 
 presumably used up all the food sources that might be available?


If inorganic biology were possible, shouldn't it use inorganic food sources?
 

  

 2. an organism which can survive only on inorganic nutrients


 ???


A bird that can live on rocks, etc.
 

  

 3. a successful experiment to create life from basic molecules

  
 Arguably the biosphere counts as this, presumably not an intentional 
 experiment.


That's begging the question. We don't know that abiogenesis is a fact, or 
if it was, we don't know that it is possible to reoccur. Our experiments 
thus far have not supported the idea that biological life can be be created 
again.
 

  

 4. a machine which seems to feel, care, and have a unique and 
 unrepeatable personal presence


 Arguably a human being is one of these


It's begging the question. I'm saying people are not like machines, 
because people are all unique but machines are not. You can't use that 
fact to claim that people are representative of machines, and then 
therefore that machines can be like people.  If I said oil and water don't 
mix, you can't say 'arguably oil is a type of water'.
 

  

 5. a mechanized process which produces artifacts that seem handmade and 
 unique
 6. two separate bodies who are the same person
 7. an organism which reproduces by transforming its environment rather 
 than reproducing by cell division


 This seems to me to have gone completely off the point.


I would need you to explain more of what you mean.
 

  

 8. an organism which emerges spontaneously from Boltzmann conditions in 
 the environment rather than seeded inheritance


 What?!? (He said billions of years, not googolplexes...!)


I didn't say Boltzmann brain, just a Boltzmann organism.
 

  

 9. an event or observation which leads us to conclude that gathering 
 energy and reproduction are sufficient to constitute bio-quality awareness.

 I don't understand that sentence. 


The whole basis of computationalism hinges on the assumption that acting 
like you are alive is the same as being alive, which I think is 
demonstrably false. We know for a fact that something that is not alive can 
seem like it is. We know that a machine can produce strings of language 
that carry no meaning for it. So what is it, other than pure blue-sky 
wishful thinking, that leads us to conclude that moving a puppet around in 
the right way is going to bring Pinocchio to life?
 


 I may be missing something here but I believe the question is whether 
 machines can have experiences. Isn't a human being a machine that has 
 experiences?


No, that's begging the question. A human body may be a machine, but that 
does not mean that a human experience can be created from the outside in. 
That's what all of these points are about - a machine does not build itself 
from a single reproducing cell. A machine does not care what it is doing, 
it doesn't get bored or tired. A machine is great at doing things that 
people are terrible at doing and vice versa. There is much more evidence to 
suggest that human experience is the polar opposite of mechanism than that 
it could be defined by mechanism.

 Maybe I was premature in saying it was promissory...it would appears that

 It is almost applicable, but the hard part is that it is blind to its 
 own blindness, so that the certainty offered by mathematics comes at a cost 
 which mathematics has no choice but to deny completely. Because mathematics 
 cannot lie, 


 G* proves []f

 Even Peano Arithmetic can lie.  
 Mathematical theories (set of beliefs) can lie.

 Only truth cannot lie, but nobody know the truth as such.


  Something that is a paradox or inconsistent is not the same thing as an 
 intentional attempt to deceive. I'm not sure what 'G* proves []f' means 
 but I think it will mean the same thing to anyone who understands it, and 
 not something different to the boss than it does to the neighbor.


 Actually it will have as much meaning as there are correct machines (a 
 lot), but the laws remains the same. Then adding the non-monotonical 
 umbrella, saving the Lôbian machines from the constant mistakes and lies 
 they do, provides different interpretation of []f, like

 I dream,
 I die,
 I get mad,
 I am in a cul-de-sac
 I get wrong

 etc.

 It will depend on the intensional nuances in play.


 Couldn't the machine output the same product as musical notes or colored 
 pixels instead?


 Why not. Humans can do that too.


If I asked a person to turn some data into music or art, no two people 
would agree on what that output would be and no person's output would be 
decipherable as input to another person. Computers, on the other hand, 
would automatically be able to reverse any kind of i/o in the same way. One 
computer could play a file as a song, and another could make a graphic file 
out of the audio line out data which would be fully reversible to the 
original binary file.




  







 it cannot intentionally tell the truth either, and no matter how 
 sophisticated and self-referential a logic it is based on, it can never 
 transcend its own alienation from feeling, physics, and authenticity. 


 That is correct, but again, that is justifiable by all correct 
 sufficiently rich machines.


 Not sure I understand. Are you saying that we, as rich machines, cannot 
 intentionally lie or tell the truth either?


 No, I am saying that all correct machines can eventually justify that if 
 they are correct they can't  express it, and if they are consistent, it 
 will be consistent they are wrong. So it means they can eventually exploits 
 the false locally. Team of universal numbers get entangled in very subtle 
 prisoner dilemma. 
 Universal machines can lie, and can crash.


 That sounds like they can lie only when they calculate that they must, not 
 that they can lie intentionally because they enjoy it or out of sadism.


 That sounds like an opportunistic inference.


I think that computationalism maintains the illusion of legitimacy on basis 
of seducing us to play only by its rules. It says that we must give the 
undead a chance to be alive - that we cannot know for sure whether a 
machine is not at least as worthy of our love as a newborn baby. To fight 
this seduction, we must use what is our birthright as living beings. We can 
be opportunistic, we can cheat, and lie, and unplug machines whenever we 
want, because that is what makes us superior to recorded logic. We are 
alive, so we get to do whatever we want to that which is not alive.

it, and we don't recognise the fact. It would be important to know what
that something else is before one can construct an argument. (For example,
I believe Bruno thinks the something else is an infinite sheaf of

 I think Craig would say he does think computers (and many/all other

 You're half right. I would say:

 1. All experiences correspond to some natural thing.
 2. Not all things are natural things. Bugs Bunny has no independent
 experience, and neither does Pinocchio.
 3. Computers are made of natural things but, like all machines, are
 ultimately assembled unnaturally.
 4. The natural things that machines are made of would have to be very
 low level, i.e., not gears but the molecules that make up the gears.

 Unless a machine used living organisms, molecules would probably be
 the only natural things which an experience would be associated with. 
 They
 don't know that they are part of a machine, but there is probably an
 experience that corresponds to thermodynamic and electromagnetic
 conditions. Experiences on that level may not be proprietary to any
 particular molecule - it could be very exotic, who knows. Maybe every 
 atom
 of the same structure represents the same kind of experience on some
 radically different time scale from ours.

 It's not really important - the main thing is to see how there is no
 substitute for experience and a machine which is assembled from unrelated
 parts has no experience and cannot gain new experience in an alien 
 context.

 I think that a machine (or any inanimate object or symbol) can also
 serve as a vehicle for synchronicity. That's a completely different thing
 because it is the super-personal, holistic end of the sensible spectrum,
 not the sub-personal, granular end. The creepiness of a ventriloquist

 your

 The thing that makes sense to me is that the richness of sensation and

 can be controlled from the outside. If we put nano-tech extensions on some
 living organism, then sure, the organism could learn how to use those
 extensions and evolve a symbiotic post-biology. I don't think that project
 would be controllable though. They would not be machines in the sense that
 they would not necessarily be of service to those who created them.

 Thanks for your answer.  That was not quite what I was asking though.
 Let's say the nano-tech did not extend some living organism, but were some

For John Clark

2013-10-15 Thread Jason Resch
(And others who ignore the importance of first person views when it comes
to duplication.)

I invite you to read what Hugh Everett had to say on the matter:


I believe that my theory is by far the simplest way out of the dilemma,
since it results from what is inherently a simplification of the
conventional picture, which arises from dropping one of the basic
postulates--the postulate of the discontinuous probabilistic jump in state
during the process of measurement--from the remaining very simple theory,
only to recover again this very same picture as a deduction of what will
appear to be the case for observers.

He notes the appearance of probability from the perspective of observers,
despite an entirely deterministic theory, saying:

Our theory in a certain sense bridges the positions of Einstein and Bohr,
since the complete theory is quite objective and deterministic...and yet on
the subjective level...it is probabilistic in the *strong sense* that there
is no way for observers to make any predictions better than the limitations
imposed by the uncertainty principle.

So he explicitly says the fully deterministic theory (fully deterministic
from the God's eye, third person view) leads to probabilistic
(random/unpredictable) outcomes from the subjective observer's first person
view.  Even an observer who had complete knowledge of the deterministic
wave function and could predict its entire evolution could not predict
their next experience.


Finally, we have this exchange between Everett and other physicists,
including Nathan Rosen, Podolsky, Paul Dirac, Yakir Aharanov, Eugene
Wigner, and Wendell Furry at Xaviar College:

Everett:
Well, the picture that I have is something like this: Imagine an observer
making a sequence of results of observations on a number of, let's say,
originally identical object systems. At the end of this sequence there is a
large superposition of states, each element of which contains the observer
as having recorded a particular definite sequence of the results of
observation. I identify a single element as what we think of as an
experience, but still hold that it is tenable to assert that all of the
elements simultaneously coexist.  In any single element of the final
superposition after all these measurements, you have a state which
describes the observer as having observed a quite definite and apparently
random sequence of events. Of course, it's a different sequence of events
in each element of the superposition. In fact, if one takes a very large
series of experiments, in a certain sense one can assert that for almost
all of the elements of the final supeprosition the frequencies of the
results of measurements will be in accord with what one predicts from the
ordinary picture of quantum mechanics. That is very briefly it.


Podolsky: Somehow or other we have here the parallel times or parallel
worlds that science fiction likes to talk about so much.

Everett: Yes, it's a consequence of the superposition principle that each
separate element of the superposition will obey the same laws independent
of the presence or absence of one another. Hence, why insist on having
certain selection of one of the elements as being real and all of the
others somehow mysteriously vanishing?

Furry: This means that each of us, you see, exists on a great many sheets
or versions and it's only on this one right here that you have any
particular remembrance of the past. In some other ones we perhaps didn't
come here to Cincinnati.

Everett: We simply do away with the reduction of the wave packet.

Poldolsky: It's certainly consistent as far as we have heard it.

Everett: All of the consistency of ordinary physics is preserved by the
correlation structure of this state.

Podolsky: It looks like we would have a non-denumberable infinity of worlds.

Everett: Yes.

 Technically they can. They can correctly predict that they will have *all*the 
 available experiences. It's only after the measurement has been made
that there is an *appearance* of probability, with each duplicate feeling
that he has experienced a probablistic event. But that feeling only arises
from the assumption (or gut feeling) that there is only one observer, both
before and after the measurement.

That's the third person view. The view of the wavefunction's  
evolution.  That is completely predictible.


Whether or not you will measure the electron to be spin up or spin  
down you can't predict in advance.  That is because you experience  
both but neither experiences it as being both spin up and spin down.

Apparently not.  John refuses to accept that a fully deterministic  
process can lead to the subjective appearance of randomness when  
duplication is involved. (the third step of the UDA)

I agree with the text above. The part I was contesting was where you  
said that one can predict their next subjective experience.


When you say that one could answer they will experience all  
perspectives, then you are no longer speaking of a subjective  
experience.
