I think you were just trying to say that the space of brains (and

Unless you allow brains to grow infinitely big, there are only a

Assuming comp. If the brain is defined by its material quantum  
state, and assuming electron position is a continuous observable,  
then we can have an infinity of brains, even when limiting their  
size.


Why observable?  Why not just variable - which it is in current  
formulations of QM.


?
Position, in QM, is represented by an observable (some operator in a  
Hilbert space). Its eigenvalue are the variable which can be  
instantiated by a measurement. I am not sure I grasp the remark, nor  
that it would change anything. If some physical data are actually  
infinite, a non-computationalist can argue that you can emulate an  
infinity of mind states in a finite portion of some physical-space-time.






But with real valued variables can't there be hypercomputation?


Yes. But you can have hypercomputation also when working with only  
natural numbers, like a machine computing functions from N to N with  
the help of the Halting Oracle, or with any pi_i or sigma_i oracles.   
We know this enlarge properly a lot the class of computable functions.


I am not convinced by the argument of Kent, but perhaps an improvement  
can be made. Von Neumann wrote a paper where he estimated that the  
probability of self-duplication machines apparition on Earth is very  
low. I am not convinced, but this still suggests that the theory of  
evolution, when precise enough, might see the trace of the  
multiverse, in case that probability is so low that the origin of life  
involves non trivial quantum computations.


Gödel also suggested that science might have to admit a God in case  
the speed of evolution violates the (known) physical laws. Apparently  
Godel didn't see the Many-world alternative to God, for that function.


Godel and Einstein missed the many-thing idea, and I see people  
resist. Yet, I think that with mechanism, we just cannot avoid that  
multiplication when we believe statements like Goldbach conjecture is  
true or false.

Same for me!

I was just alluding that I have much doubt that the physical

funny, and once immortal, people will love forgetting and

When human will be technologically immortal they might regret it and

resetting, or erasing memories at least, becomes necessary  
eventually if one is to have (and remember) new experiences. To

The real art is in forgetting, and putting the less relevant  
information in the trash, and keeping the most relevant one, instead  
of the contrary.


The molting of the spiders is also quite intriguing in question of  
dying and surviving. It is easy to conceive immortal creature with non

all their experiences, without noticing it of course.








In buddhist term, terrestrial or technological immortality might  
only be a manner to prevent the nirvana, and to pursue our staying

Well that's true, in Buddhist terms... is there any correspondence  
between Buddhism and comp?


Plotinus, and most of the neoplatonism, is close to the teaching of  
some buddhism, and there are books on that subject.
Then I propose a lexicon between Plotinus and the machine's talk about

I think all mystics are close to what the universal machine discover

It is, very roughly,  the difference between Plato and Aristotle, or

(If so should I assume we're talkng about a countable infinity?)

I think you have to specify whether comp means merely that a  
computer simulation of a brain can be conscious or go the whole way  
with Bruno's conclusion that there is no actual physical computer  
and all possible computations are necessarily implemented by virtue  
of their status as platonic objects.



It is not so much in virtue of their status as platonic object (which  
seems to imply some metaphysical hypothesis), but in virtue of being  
true independently of my will, or even of the notion of universe, god,  
etc.


You need just to assume, or accept as true, relations like x + 0 = x,  
for all x, etc. It is a very weak form of realism, and basically, this  
is assumed by all scientists.


*After* UDA, the assumptions are no more than classical logic and ,  
for all x and y:


0 ≠ (x + 1)
((x + 1) = (y + 1))  - x = y
x + 0 = x
x + (y + 1) = (x + y) + 1
x * 0 = 0
x * (y + 1) = (x * y) + x

The boxes and diamond are defined in that theory, the theology and  
physics is derived in the extensions of that theory (the observers)  
simulated by that theory.


There are many other equivalent theories.

There are some metaphysical or theological consequences, clear with  
comp, but except for the yes doctor, there is no special ontological  
commitment done, not even on the numbers, that is no more than in  
Euclid proofs of the infinity of the prime numbers.


The computations are implemented in virtue of the consequences of the  
axioms above.

So the idea is that in a multiverse we - indeed all animals (and

somehow equivalent to the three descendants on a quantum coin  
toss one.


I'd say it's coherent, but inapplicable because a universe where a  
species with strategy B occasionally gets wiped out, but those with  
strategy A don't is a very unlikely universe.  But if universes were  
like that, so getting wiped out was correlated with reproductive  
strategy, then it's an interesting question whether 'natural  
selection' under MWI is different than for a single universe.




I guess my next question is, what could such a reproductive  
strategy possibly look like in real life, given that most animals  
have no access to quantum coin tossing?


I suppose you could look at the exigencies of life and mutation and  
reproduction as providing the quantum coin tosses.  But I don't  
think it's realistic because getting wiped out as a species is more  
a question of ecological niche and sheer numbers than reproductive  
strategy.

If y consciousness is really needing the exact material bile in  
my liver, the other brain will just not be similar enough, and it  
is conceivable that although conscious like me, the copy might be  
another person. This makes no sense, if you use some form of comp.




This is a concrete, no nonsense, no consciousness-flitting-about  
type of theory - but your consciousness will still effectively  
flit about because you can't be sure which copy you are.


Assuming comp. If the exact infinite state of the bile is  
required, then by definition, the other person is a different  
person. I agree this seems absurd, but that is a comp prejudice.  
After all, I *can* conceive that the other might be an impostor  
an authentically other person.


If consciousness is secreted by the brain, then if you make a

yes, but if the brain secrets consciousness, and if my identity is  
in the identity of the matter involved, the consciousness is  
conceivably similar, but not mine. I agree this makes not a lot  
of sense, but this is because we put the identity (and  
consciousness) in the relational information, and this uses comp.





The actual theory of consciousness doesn't make any difference  
here.
The claim that the copy isn't really the same person is  
equivalent to, and as absurd as,  the claim that I'm not the same

I agree, but I think you are using some functionalism here.  
Someone who associates consciousness to its actual matter might

seven years (assuming the whole material body constitution has

It doesn't follow that if consciousness is substrate specific it  
can't be duplicated;


OK. But the point is that it might, and that would be the case if  
my consciousness is attached to both the exact quantum state of  
my brain and substrate specific (which is a vague thing, yet  
incompatible with computationalism).




it can in fact be duplicated in a straightforward way, by making a  
biological brain.


But we do have evidences that biological copying is at some rather  
high level, and that it does not copy any piece of matter. It  
replaces all molecules and atoms with new atoms extracted from  
food.


Here I am just playing the role of devil's advocate and I assume  
non comp to make a logical point.





Even if consciousness is due to an immaterial soul one could say  
that it could be duplicated if God performs a miracle.


Right again, but here too, it might not be the case. God could  
decide to NOT do a miracle, given that It is so powerful.




The claim that the duplicated consciousness isn't really me is a  
claim about the nature of personal identity, and is independent of  
any theory of how consciousness is generated.


Not if the theory of consciousness is based on personal identity.  
Your claim makes sense again for a functionalist, but not

A functionalist could agree that a computer can replicate his

Steady on, I don't think it does that at all, unless you constrain  
the

physical world to be bounded somehow in both space and time.

I think you were just trying to say that the space of brains (and
mental states) is discrete, something I could agree with.

Unless you allow brains to grow infinitely big, there are only a  
finite number of possible brains even in an infinite universe.
Assuming comp. If the brain is defined by its material quantum  
state, and assuming electron position is a continuous observable,  
then we can have an infinity of brains, even when limiting their size.


Is electron position a continuous observable? Even if it is and  
there are an infinity of brains, why should that result in an  
infinity of minds? It would seem unlikely that brains would evolve  
so that an arbitrarily small change in the position of an electron  
would cause a change in consciousness, and we know that even gross  
changes in the brain, as occur in stroke or head injury, sometimes  
have remarkably little effect.


I think Bruno must have a materialist hat on here?!


Excellent observation! In this context I assume some no-comp, and  
matter, and real numbers, etc. I can do that too :)
It is the context of trying to understand what Stathis is saying, in a  
proper generalization of comp (still a bit fuzzy to me).





In comp the substitution level isn't necessarily at the level of  
individual electrons, surely...


The weak comp I consider is neutral on this, as long as the role of  
the minimal element is Turing emulable. It could the level of branes  
or strings, the consequences would still follow.


Non-comp needs to give a role to an actual infinities with *all* its  
decimals.







But that raises another question, for me at least - in comp are  
there only finitely many possible states of mind?



They are a priori infinite enumerable. But for some you need  
*gigantic* brain. Well, they do exist in arithmetic.





So one would literally be able to travel full circle through all  
possible minds - eventually?



The UD does that, and although there are many circles, there are  
also spirales, complex infinite histories which never close on itself.
It is hard to conclude, as the 1p and 3p relation is complex, but  
infinite self-complexifying conscious state cannot be excluded easily  
neither.
A zoom in the mandelbrot set illustrates never-ending self- 
complification. The more a tiny Mandelbrot set is tiny, the more and  
more complex will be its filaments.


For example:

Computationalism entails that every relative computational states is

Well OK, but what I've read (and indeed observed and experienced  
throughout my life) indicates that people, and most animals who  
care for their young, employ strategies which could (roughly) be  
described as male-risky, female-play-it-safe (or at least safer).  
E.g. it's the male grasshoppers who 
keep me awake with their racket, the male birds who wake me in the  
morning with THEIR racket, peacocks with the big showy tails, male  
bower birds who expend the energy to make the bowers - all males  
employing (relatively) risky strategies to attract females.  
(Because, you see, we're just naturally fabulous and you guys have  
to make the running. Sorry!)


  Kent's idea would be to look around and see whether people were  
overwhelmingly type A or type B.  If MWI is true they should be  
type B, if false type A.


Yes, I realise what he was saying. I don't think it makes much  
sense, because it would require people to believe in the existence  
of a multiverse before they could formulate a reproductive  
strategy involving that knowledge, and the idea of a multiverse  
has only existed for about 50 years.


Not believe in, just believe MWI is possibly true.  But they  
wouldn't actually have to have any opinion; that's just a way to  
explain it.  Presumably evolution would have already made the  
choice and we'd all be overwhelmingly either A type or B type,  
whether we knew it or not.  The problem would be finding out which  
we are if it's just in our genes and not necessarily consciously  
available.


I'd say more of problem for the test is that the aren't really two  
choices which are passed on genetically.  There's really nothing to  
limit one to just replacement even if there's only one universe.



Otherwise, I'd expect people to act as though they are in a single  
universe, regardless of whether that is so, because that's how  
things appear to be. I'd expect genes to exhibit a similar  
strategy - they aren't (can't be) interested in what happens in  
a parallel world which can't communicate with the one they're in.


  There shouldn't be any split along gender line.

Well there is, at least in my experience (and in various books,  
articles, nature documentaries and so on that I've come across).  
Indeed, apart from a few die-hard feminists I don't know of anyone  
who still adheres to the notion that people are blank slates and  
that gender roles are purely assigned by culture (humans exhibit  
sexual dimorphism, and brain scans indicate that it doesn't  
magically stop at our necks. Plus, why would blank-slatism only be  
true of us, but not the rest of the animal/fish/insect kingdom  
where it - often blatantly - isn't the case?)


Anyway, that's why I don't think one can sensibly analyse an  
entire species' reproductive strategy to see if it was A or B (or  
something else), because reproductive strategies tend to be gender  
specific. It seems like a daft idea - maybe it's a guy thing? ;-)


I don't understand your reasoning.  Sure guys are less risk  
averse.  But A vs B is pure win-or-lose depending on whether MWI is  
true or not.  If MWI is true then strategy B is the winner no  
matter whether you're male or female...and not by a little bit or  
just probabilistically, but exponentially, overwhelmingly better.   
If MWI is false and there's just one universe then B is an  
absolute, zero survivors loser.



The thing is even if MWI is true or not... strategy A or B are  
simply idea with no referent in the reality (even as  
possibility)... the 0.5 probability of going extinct at the next  
gen simply refer to nothing real in our reality, same thing for the  
steady reproduction... so I can't see

 Then function is always used in two very different sense, especially in
 computer science, as it can be extensional function (defined by the
 functionality), or its intension (the code, the description, the body).

 Could your functionalist say yes to a doctor, which build the right
 computer (to replicate his consciousness), and add enough original atoms
 to preserve the identity? Is someone saying yes to that doctor, but only if
 a priest blesses the artificial brain with holy water a functionalist?

 Can you describe an experience refuting functionalism (in your sense)?
 Just to help me to understand. Thanks.


A person could conceivably say the following: it is impossible for a
computer to be conscious because consciousness is a magical substance that
comes from God. Therefore, if you make an artificial brain it may behave
like a real brain, but it will be a zombie. God could by a miracle grant
the artificial brain consciousness, and he could even grant it a similar
consciousness to my own, so that it will think it is me. However, it won't
*really* be me, because it could only be me if we were numerically
identical, and not even God can make two distinct things numerically
identical.

I don't accept this position, but it is the position many people have on
personal identity, and it is independent of their position on the
possibility of computer consciousness.

 (Or an infinite number of Turing machines, according to comp ;-)

 Does comp suggest that consciousness corresponds to an infinite number of
 different possible mental states (rather than a very large, but finite,
 number of them) ?

 (If so should I assume we're talkng about a countable infinity?)

 I think you have to specify whether comp means merely that a computer
 simulation of a brain can be conscious or go the whole way with Bruno's
 conclusion that there is no actual physical computer and all possible
 computations are necessarily implemented by virtue of their status as
 platonic objects.



 It is not so much in virtue of their status as platonic object (which
 seems to imply some metaphysical hypothesis), but in virtue of being true
 independently of my will, or even of the notion of universe, god, etc.


But there is the further notion of implementation. The obvious objection is
that computations might be true but they cannot give rise to
consciousness unless implemented on a physical computer. Step 8 of the UDA
says the physical computer is not necessary; which is a metaphysical
position if anything is.


 You need just to assume, or accept as true, relations like x + 0 = x, for
 all x, etc. It is a very weak form of realism, and basically, this is
 assumed by all scientists.

 *After* UDA, the assumptions are no more than classical logic and , for
 all x and y:

 0 ≠ (x + 1)
 ((x + 1) = (y + 1))  - x = y
 x + 0 = x
 x + (y + 1) = (x + y) + 1
 x * 0 = 0
 x * (y + 1) = (x * y) + x

 The boxes and diamond are defined in that theory, the theology and
 physics is derived in the extensions of that theory (the observers)
 simulated by that theory.

 There are many other equivalent theories.

 There are some metaphysical or theological consequences, clear with comp,
 but except for the yes doctor, there is no special ontological commitment
 done, not even on the numbers, that is no more than in Euclid proofs of the
 infinity of the prime numbers.

 The computations are implemented in virtue of the consequences of the
 axioms above.
