Jesse's question is *the* important question in the list. I just recall  
it. But also, I will take the opportunity of John's question to explain  
a bit more the interview of the Lobian machine, and what that is, and  
how it helps to provide answers to Jesse's questions, when we assume  
explicitly the comp hyp. Asap, because I'm busy. I will try to give  
answers without too much technical details, but that is really what  
makes that exercise difficult. I hope I can do that already this week.   
Of course everyone can use the question of Jesse to make a bit more  
precise where they stand from the others indeed, I'm interested too.

Well thanks Russell. Note that I was not doing a critic. I have the  
usual problem with the word "philosophy", which in many places (on the  
continent means just "marxism" or the more ("postmodern") relativism.  
But here I was mainly "complaining" that sometimes people talk like if  
I was proposing some new theory or vision, like some honest pholosopher  
can do.
I am more modest than that, or ... less modest perhaps.  I just take  
seriously a very old "theory" (mechanism) and try to explain the  
consequences: the testable breakdown of materialism.

Best Regards,

Bruno

Science was called Natural Philosophy a few centuries ago. Indeed

Re: Evidence for the simulation argument

2007-04-03 Thread Bruno Marchal

Hi Mark,

Just a preliminary remark before I comment your post. Contrary to what 
Russell says in his book, I am not at all a philosopher, I am not 
trying to propose a view of the world or a conception of reality. As I 
said in the joining post my initial goal was just to understand 
molecular biology, or more precisely to understand the relation between 
molecular biology and biochemistry. In that context I have eventually 
discover Godel's proof, and through it I have guess an abstract 
biology, not dependent upon any chemistry. But this was presupposing 
some form of what later I called "comp" and I eventually realized that 
if I could relate that abstract biology with "real biology" then, in 
some deep global sense, it is (bio)chemistry which should obey to the 
law of abstract biology (despite James D. Watson's slogan). So, it is 
very early that I did understand that comp entails a reversal between 
mind and matter, between physics and machine's number theoretical 
bio-psycho-theo-logy. The rest in the effort to communicate that 
*problem*: I mean, that if comp is true, then the physical science have 
to be reduced to an abstract digital biology.

This is all what I say: if COMP is true, then the laws of physics are 
not primary. Comp is really a precise version of what Peter called 
standard computationalism. It is just a computer science update of 
Descartes' Mechanism, the idea that we are, from a correct third person 
point of view, machine (cf "yes doctor"). The fact that "matter" (as 
substrate; not as appearances) disappears is just an unavoidable 
consequence of comp. This I can, and I already have, explain on the 
list in all details (just ask if you want we go through the UDA again). 
I know we are wrong on this mind/body issue since more than 1500 years, 
i.e. since the scientist, due to "political pression" abandoned 
theology to the political authorities.  The millenium before it is 
plain that the intellectuals were aware that the mind/matter primacy 
question was an OPEN problem. All what I show is that with comp, it is 
still an open probIem. I think the Roman Church has some responsibility 
in making many people taking for granted that matter is an independent 
primary substrate making up our reality. It is a sort of "metaphysical 
demagogy", given that we have been probably "programmed" by million of 
years evolution to take our neighborhood for granted. Of course this 
idea could be true of course, but then comp has to be false. For comp 
being false you have to put in our body some infinite non computable 
object, that is, something which cannot be emulated even by a quantum 
computer.  People are free trying to develop such theories, but those 
who are serious until now have to make speculative move (like the 
falsity of QM, for example). Actually people are free to take the 
reversal result as an argument against comp, but then it is certainly 
not a knock down, for the reason that computer science is full of 
counter-intuitive results.

Indeed the second part of my work consists in interviewing a 
(sufficiently chatty, lobian) universal machine, and the discovery is 
that the machine introduced many subtle nuances on the 
geometrical/physical difference corresponding to the difference between 
necessary points of view (1-person, 3-person, 3-person plural, 
computable, true, provable, etc.). Now, when you just define the 
computationalist notion of matter, which, by the UDA, is given the 
third person sharable measure on uncertainty on accessible UD states, 
in the language of a lobian machine, you get a quantum logic which 
confirms (≠ proves) comp, and thus does not (yet) refute it.

I will say more in a post to John, but the relation are any one that 
you can define with classical logic languages and  addition and 
multiplication. For example, the relation "x is little than y" , which 
has the definition: Ez(x + z = y)   (Ez = it exists a number z), or the 
relation (x divides y) which has the definition Ez(x * z) = y. Godel 
has shown you can define most computer science notion in arithmetic, 
meaning by similar definition (involving only addition and 
multiplication). His result show that we cannot unify completely 
arithmetical truth, i.e. there is no theory capable of proving all true 
arithmetical proposition.

Mark,
you asked interesting questions, but I think the fundamental ones are still
'out there':
MP:(bold and in bold):
"I mean the big and unanswered question is WHERE are numbers?
I would ask (joining your heresy):

1. Where did numbers come from? (an answer may be: They are GOD to believe
in).

2. How do they act?
Bruno wrote: the relationship between numbers. How does a "RELATIONSHIP"
act? it is an abstraction. Only substrates IN relationship act. The numbers
are abstractions (or: the contents we assign to them are abstractions?) so
here we face abstractions of abstractions. If one considers the
not-so-physical world (numbers?)
  -  a-spatial  -  (and of course   -  a-temporal  -), your question is out
of whack.
*MP next:
" what I am saying is that numbers need something which is not numbers -

I believe it can be incorporated into the identification of
  "n u m b er "

if you ask only about their existence. Anything exists what we think about -
if not otherwise: in our thought. (I just had some exchange on this with
Stathis in a different aspect.)

MP: But what *relation* is there really? I just feel like this
kind of discussion goes round and round in endless convolutions.
Platonia is some kind of Never-never land; that numbers exist
anywhere except inside human skulls and nowadays within
phenotypic prostheses like electronic computers is NOT a proven
fact, it is a glorious assumption!

I mean the big and unanswered question is WHERE are numbers?
Mathematicians now seem to be very sophisticated with WHAT
numbers could BE, and _do_ also apparently, but very very big
numbers which could represent everything significant about
you, me, or the likelihood of a self referencing computer
working out that it knows that it knows something really
important, how can these 'relate'? Surely they have to be
related by someone or something else! I guess what I am saying
is that numbers need something which is not numbers in which, or
by means of which they can exist for each other. I call it
'existence', and use the name of Janus as my symbol or emblem of
this. But I don't expect any such symbol or emblem to resolve 
the paradoxes of our existence and experience of existence. As 
far as I can see, which admittedly is not very far, all 
explanations that purport to be *ultimate* explanations are 
doomed to a process of infinite recursion and regression.

There was an Englishman called Kenneth Craik, who wrote a little 
book called 'The Nature of Explanation'. Unfortunately he died 
in his early thirties in a car accident in 1945 I think. I go 
along with his thesis - as I remember it from reading the book a 
decade or more ago - that the representational power of 
mathematics stems from its evolution of complex mathematical 
objects out of the interactions of simple elements, which can 
mirror many significant aspects of the physical/noumenal world 
because the latter seems to be manifesting a closely analogous 
evolution of aggregations of fundamental chemical elements, 
sub-atomic particles and so forth.

For better or worse I must advocate what is hereabouts a virtual 
heresy: that people can never be reduced to numbers. To be a 
person entails the experience of 'I' and 'thou', 'me' and 'you'. 
There can be no me without you and no 'us' without 'them'. If a 
modest Loebian machine cannot work this out, then it needs to go 
back to school. Perhaps it can though, [if all worlds are 
possible and must happen], maybe it is just a matter of time 
before one or more smart, introspective, self-sustaining 
processors/processes emerges from a BOINC type distributed 
system. My bet is that the Silico-Electric ONE [or two, ...] 
will coalesce around the control and accounting of money, money 
being the embodiment of negative entropy in the cultural world. 
For what it's worth I think that such a creature will realise 
that ethics is part of the foundation of its world: a 
fundamental tool for the maximising of 'negative entropy'.

The goal of the UDA is not  to explain anything. The goal of the UD 
Argument is to show that the physicalist notion of Matter does not 
explain neither appearance of matter nor mind.
UDA is negative. It only illustrate that with comp the mind body 
problem is two times more difficult than it is usually thought. You 
have to explain BOTH Mind and Matter (and actually you have to explain 
matter from mind, cf the reversal).

Only when UDA is translated in the language of a Lobian machine, did it 
begin to give positive and verifiable informations on 
matter/appearances.

The whole point of Godel's proof is that, exactly like you can define 
"prime" in the language of Peano Arithmetic PA (or weaker non lobian 
entity like Robinson Arithmetic),  you *can* define "being the godel 
number of a proof by PA"  *in* PA.

In all situation, when we are using a language we have to agree on some 
convention. Even the question "is the number 12345678987654321 prime or 
not" presuppose the conventional use of base ten position notation for 
number and the arithmetical definition of primeness.
The same occurs for the notion of arithmetical provability.
Of course the finite string "12345678987654321" could be a godel number 
of a proof or not depending of the way you represent the variable or 
the quantifier or the connector in term of numbers, but the *string* 
"12345678987654321" will represent a prime number or not according to 
the way you represent decimal numbers in Pean Arithmetic. It is just 
because we already agree, since high-school, on conventional notation 
for number that you can directly talk about the *number* 
123456787654321".  If we would have learn in high school some canonical 
way to represent proof (in PA) by numbers, like those used to explain 
to PA what a proof is, I would have been able to say yes or no 
directly.

Now, concerning Peano Arithmetic (PA), obviously (ask if not) 
12345678987654321 is NOT the godel number of a proof of f 
(independently of any choiçce of proof representation). This is because 
PA is consistent, so no number can represent a  proof of a falsity f.
And a lobian machine like ZF can prove that.

Note that, although Stathis defends many argument which are going in 
the direction of the ultimate consequence of comp, I do agree with some 
critics you are doing here and there. To believe that the observer 
moment OM are disconnected is perhaps a remnant ASSA thought (Absolute 
Self Sampling Assumption).

Let us try to be a little more specific. From a computational point of 
view, a computation can be considered equivalent with a proof of an 
arithmetical statement having the shape "it exists a number having this 
or that decidable property", that is "En P(n)" (it exists a n such that 
P(n)). So the universal dovetailer infinite execution is equivalent 
with the set of true Sigma1 sentences together with their proofs. So we 
can define easily a notion of atomical (primitive) third person 
"Observer Moment" by them. I put OM in quotes, because strictly 
speaking OM are conceived as first person experience and not as third 
person computational states. The UD Argument does force us to take 
those distinction into account. In particular it  shows that, to 
predict anything physical, among other things, we have to define a 
notion of first person plural indeterminacy, bearing on the OMs as seen 
by a machine itself embedded in UD*.

What happens is that each internal view, or hypostases, like the first 
plural person points of view, are defining a non trivial (thanks to 
Godel & Co.) mathematical and quasi geometrical structure on the OMs. 
That is each hypostases relate the OMs. They single out arithmetical 
relations in between the OMs. They remains disconnected, in a sense, 
like the numbers themselves can be considered disconnected. But of 
course, numbers are connected to each other by the usual arithmetical 
relations (definable in term of sums and products), and when the 
internal points of view are taken into account, we got for each of them 
a collection of different connections. If you recall some of my older 
post, the three primary hypostases rise Kripke multiverses, and the 
secondary (material, physical, natuiral) hypostases rise Scot-Montague 
sort of continuum topological multiverses, where the OMs appears to be 
as connected as "points" on continuous manifolds.

Now if comp is correct, it is expected that the relations between the 
OMs, from some first person point of view, restricted to the atomical 
Sigma1 propositions (by the UDA) gives rise to the laws of physics, 
defined by what is invariant for all observer point of views (arguably 
given by the third or fourth or fifth "hypostases"). Those are indeed 
the one which technically give purely arithmetical interpretation of 
Quantum Logic, the real signification of which remains to be seen (to 
be sure).

The lobian machine already gives some clues that a *physical* 
computation has to be given by a

I didn't think godel numbering was unique?  If I just cite a number, like 
12345678987654321, is it either the godel number of a proof or not?

It is an inherent relation like being prime, or being the godel number

What are those relations?  Is it a matter of the provenance of the numbers, 
e.g. being computed by some subprocess of the UD?  Or is an inherent relation 
like being relatively prime?

With comp, what holds 'your lot" together are the relation between 
numbers. The apparent third person infinite regression stops at the 
level of those relations. The first person is most probably confronted 
with many infinities, but this should not be considered as 
problematical.

Why can't we measure the state of something? Even with just QM, the 
many-world idea has been invented for abandoning the idea that a

We must acknowledge indeterminacy once we postulate comp, given that it

Not really. An history can be revised infinitely often so that our

OK, I just read "bitstring" as something generated by a computer, but I see
that you deliberately differentiate the descriptions from the Schmidhuber

That's not an assumption I make. The only thing given "priveleged
ontological status" are the descriptions (or infinite length strings -
binary or in your choice of alphabet). These are not the
outputs of any computational process, although they can be considered
as generated dynamically by a UD if you wish (although not necessary).

I don't mean the white rabbits from the Turing machine, I mean the ones
outside it. If we accept that an abstract machine can just exist, without
benefit of a separate physical reality, why not also accept that
non-computational talking white rabbits can also just exist? That is, why
should computations have a privileged ontological status in the everything?

Actually, this is exactly what I do claim, so if you think I haven't
succeeded, I'd be very interested in learning why.

Note that the non-appearance of white rabbits comes from what I call
"robustness" of the observer, and robustness is not a general property
of Turing machines, which is why the white rabbit problem seems so
intractable in comp.

I argue why robustness should be a very likely property of observers
from evolutionary reasons, but perhaps the weakness of the argument is not yet
calculating the relative proportion of robust observers to non-robust
observers and relating this to the relative proportion of white
rabbits. I certainly believe it should more than compensate, but
perhaps I'm being overly optimistic.

I don't believe either one - I just contemplate them. ;-)  

Since it is not at all clear to me that Peano arithmetic, or any mathematics, 
exists I'm uncertain as to whether there is greater explanatory power in your 
UDA as compared to Peter's "some things exist and others don't".

When you've written this before I've asked what contradiction you derive from 
the conjunction of materialism and computationalism.  IIRC you said there was 
not a contradiction.

But you are right, I should study your argument more carefully; I don't really 
see how you get QM, much less particle physics, out of it.

Re: Evidence for the simulation argument

2007-03-17 Thread John M
I was so glad to have some 'text' on UD(A),  comp,  the P-words (Platonia, 
Paeano, Plotinus), the hypostases, in your post. Alas! Still all techy, only 
for the adepts. Not in Mark's required "plain language". (English or what?) 
(I still stumble among them).  
My question now:
How do we distinguish "Everything" from "Almost Everything"? We are still 
'walled in' by our (or: OK, let's call it:  the Loeb machine's) knowledge base. 
How can we know that we include things we do not know ABOUT? (Part of the real 
total Everything, of course) and build our 'world' on a partial model - called 
(our?) "Everything"? Then, by some event unforeseeable some 'left-out' effect 
may show up and we happily and self-justifiedly refuse it, as nonsense 
(happened many times in the conventional reductionist sciences). 
How are we better? 
We have no idea if we know but a negligible bit or almost all. We may be the 
laughing stock for an alien with wider knowledgebase (and: 'smarter'). 
Ad vocem 'smarter': 
I am sorry for the greatgrandkids who - in your remark of yesterday may not be 
smarter than we are, just have a wider source of information (epistemy). Does 
that mean that you do not believe we are 'smarter' than humans of 2-3 millennia 
ago? (Could be, because you base much knowledge on Plato etc., - the old 
Greeks). I still hold to the Leninian wisdom that quantity turns into quality 
and increasing the info-basis MAY(?) result in also smarter understganding - 
i.e. better wisdom. 
So I put on hold my regret for the greatgrandkids for now.

What I meant was the naive interpretation of "everything exists": cartoon
characters in cartoon worlds *just there* rather than generated by some
computer simulation or set of physical laws, as our universe seems to be. If
you look at only computations in Platonia, you could argue that such
structures (which as a matter of fact could be generated computationally, so
perhaps non-mathematical was a poor choice of words) would be of low
measure. However, what of the ones "outside" the computer? It seems to me
they should have the same ontological status as the abstract computer, but
it is then impossible to assign them a measure which makes the weirder ones
less likely, as has been done with computation.

No I would agree that an ensemble theory that includes some measure relative to 
a well define anthropomorphic principle has some explanatory power.  For 
example I would expect it to show that there is a higher probability of an 
intelligent life form finding intelligence to be rare and widely scattered.  
From what we know now, it seems that there could universes in which almost 
every star had a planet with intelligent life and one would be more likely to 
find oneself in such a universe than in the one we observe.  Vic has only 
considered "everything" in the very narrow sense of a range of values for the 
19 parameters of the standard model - not the much broader "everything" of 
Tegmark or even Bruno.

I guess that depends on what you mean by "mathematical structures".  I would 
take any non-contradictory set of axioms to define a mathematical structure.  
I'm not sure what it would mean to include self-contradictory "structures".  If 
you regard "mathematics" as a game of propositions it just means every wff is a 
theorem.  But if you regard "mathematics" as existing (even in Platonia) I'm at 
a loss.

You disagree that ensemble theories in conjunction with the anthropic
principle offer a possible explanation for the fine tuning of physical
constants in our universe (supposing there is fine tuning for the sake of
argument - I know Victor Stenger disagrees)? Of course, we are then left
with trying to explain why the ensemble, but that's the nature of any
explanation, including theological ones.

And while we're at it, why exclude non-mathematical structures? There seems
to be no reason why an abstract machine running a simulation of a fantastic
world should be ontologically privileged compared to the fantastic world
just existing complete in itself, not generated by any computation. This
would be closer to most forms of Idealism in Western philosophy, including
Plato's. Pythagoras was closer to the view that everything is made of
numbers.

One response to this idea is that the non-computational worlds are overrun
with white rabbits, whereas the computational worlds allow the calculation
of a local measure, such as Russell Standish has described, which explains
the orderly universe we know. However, this doesn't explain why the
non-computational white rabbits don't suddenly intrude in the next moment:
what's to say that their relative measure should be less than the orderly
computational worlds' relative measure?

And how do things "run" in Platonia?  Do we need temporal modes in logic, as
> well as epistemic ones?


No, it would be like a block universe.

It's no explanation either.  It's just "Everything exists and what you 
experience is just what you experience."  which Occam's razor trimes to "What 
you experience is just what you experience".

But what is Platonia - Tegmarks all mathematically consistent universe?  or 
Bruno's Peano arithmetic - or maybe Torny's finite arithmetic (which would be a 
much smaller "everything").

And how do things "run" in Platonia?  Do we need temporal modes in logic, as

If only one part of the possible actually exists, that isn't like being the
one person in a million who has to win the lottery, it is more like waking
up to find that money has miraculously appeared in your bedroom overnight
without there being any lottery. We could say "that's just the way it is",
but it could have been an infinite number of other ways as well. On the
other hand, if everything exists, it is no surprise that you and every other
particular thing exist. The only thing that needs ontological explanation is
the everything: why everything rather than something or nothing? If it were
possible that the reality we experience could be a simulation running on an
abstract machine in Platonia, that would be an answer to this question,
because the machine in Platonia can't not run. That's highly speculative, of
course: maybe the brain will turn out to be non-computational, or maybe
someone will come up with a formulation of computationalism which defeats
Putnam/Maudlin/Marchal type arguments, and we are back with a physical
Universe without ultimate explanation.

Actually, mathematicians have already developed ideas along these 
lines--google "hyperreal numbers" (see 
http://en.wikipedia.org/wiki/Hyperreal_number for starters) and 
"non-standard analysis" (see

There are factors creating a local measure, even if the Plenitude is
infinite and measureless. Although the chance that you will be you is zero
or almost zero if you consider the Plenitude as God's big lucky dip, you
have to be someone given that we are talking about observers, and once you
are that fantastically improbable person, it becomes a certainty that you
will remain him for as long as there are future versions of him extant
anywhere at all. Thus, the first person perspective, necessarily from within
the plenitude, makes a global impossibility a local certainty.

When human beings think of "infinity", they think of a *very* big set,
where the end of the set is hidden in a big black cloud, far, far
away.  In that way they can say that you have a mapping of the set onto
a true subset of the set, because they only see the visible part of the
set, and there it is true that there is such a mapping there.  But what
happens inside the cloud they don't see.  They don't see that there are
mappings missing in the end of the set...

When it concerns mathematics, I have developped a set of integers that I 
myself call "unnatural numbers".  An unnatural number U is an integer 
that is bigger than every natural number N.  And the inverse of an 
unnatural number (1/U) is more close to zero than any real number.  You 
can count with these unnatural number in the same way as ordinary 
integers.  So you will have that U+1 is not equal to U, and N*N << 
sqrt(U), and so on.

Tegmarks argument does not require that the universe is infinite.  It 
only requires that the universe is *very* big.  So the universe can 
still be finite.  If the universe is *enough* big it will contain many 
exact copies of our own part of the universe...

There are related examples, like letters of the alphabet, which survive even
non-topological transformations and defy any algorithmic specification.
Nevertheless, any particular concrete example of a knotted string or letter
on a page is completely captured by a physical description. There is no
special knottiness or letterness ingredient that needs to be added to ensure
that they are knots or letters.

Yes, I think there's a grain of truth in that.  The integers aren't *just out 
there*.  By Peano's, or anyone else's, axioms they are generated as needed.  We 
don't want to run out so we (except Torgny) always allow one more, but we never 
need the whole set at once until we want to make diagonalization arguments.

If you see each integer with a successor notation, 2 is S(1) and 3 is S(2) 
which is S(S(1)) and so on, you see that "big" integers contains the "small" 
integers and the smalls are over represented... just a though ;-)

Another observation refuting Tegmark! :-)

Seriously, even in the finite universe we observe my probability is almost 
zero.  Almost everything and and everyone is improbable, just like my winning 
the lottery when I buy one a million tickets is improbable - but someone has to 
win.  So it's a question of relative measure.  Each integer has zero measure in 
the set of all integers - yet we are acquainted with some and not others.  So 
why is the "acquaintance measure" of small integers so much greater than that 
of integers greater than 10^10^20 (i.e. almost all of them).  What picks out 
the small integers?

OK, but there are other questions that defy such an explanation. Suppose the
universe were infinite, as per Tegmark Level 1, and contained an infinite
number of observers. Wouldn't that make your measure effectively zero? And
yet here you are.

But components are only part of a reductionist model - it also includes the 
interactions of the components, e.g how an electron interacts with a proton.  
To identify scientific reductionism with 'component-analysis' is a straw man.  
No one is satisfied with a reductionist model that just names components - the 
model must be able to go the other way and synthesize the behavior of the thing 
modeled.  Modeling a hydrogen atom as an electron interacting via photons with 
a proton is a successful model because it predicts behavoir of the hydrogen 
atom, e.g. it EM spectrum, its stability, the heat capacity of an H2 gas.

Then how can we ever acquire additional knowledge?  The whole point of models 
like particles is to extrapolate beyond what we can observed.  When such 
extrapolations agree with further observations we put greater credence in them. 
 When the credence is great enough we start taking the model to be "known" - at 
least until we find a problem with it.  This is nothing esoteric, it's the way 
we learn what tables and chairs are as well as protons and electrons.

Are we back at the "Aris-total" i.e. the "sum" considered "more" than its

It is in our many centuries old explanatory ways to say 
a proton and an electron make a H-atom and vice versa. 

First off: hydrogen (gas) is not the assemblage of H-atoms, it is an 
observational item that - when destructed in certain ways - results in other 
observables resembling H-atoms or even protons and electrons (if you have the 
means to look at them - not in an n-th deduction and its calculations).  Same

  If you admit non-local hidden variables then you can have a theory like 
Bohmian quantum mechanics in which randomness is all epistemological, like 
statistical mechanics, and there is no place for multiple-worlds.

  I'm not sure what you mean by "locally".  Since they have opposite charge 
they will be attracted by photon exchanges and will fall into some hydrogen

Re: Evidence for the simulation argument

2007-03-15 Thread John M
I looked at your paper, interesting. 
One question:
what do you mean by "exist"
(Notably: "does NOT exist)?

We think about it (no matter in how vague terms and weak understanding), we 
talk about it, our mind has a place in our thinking for that term, - does this 
not suffice for (in a WIDER??? meaning) existence? 
I agree: it is  logically (physically?) hardly identifiable but do we stand 
only on a (material?) physical basis? 
And I make no difference between infinite small and infinite big. None of them 
understandable. Brent's 'infinitesimal' is a good idea in this topic, yet I 
consider it scale-oriented, an infinitesimally close in 1000 orders of 
magnitude smaller scale can be 'miles' away. (No 'real' miles implied) -

Well it doesn't exist under the assumption that it doesn't exist.  I actually 
agree with you that it doesn't exist - though not because it's *logically* 
impossible.  I think what you've shown is that there are other consistent 
number systems - which just illustrates the point that what you get from logic 
and mathematics depends on what you take as axioms and rules of inference.

But the problem is that a lot of mathematics would become very difficult and 
convoluted if we didn't allow infinity (and infinitesimals).  This doesn't 
bother physicists much because they are accustomed to regarding mathematics as 
an approximate model and only using as much "infinity" as seems useful.

If you admit non-local hidden variables then you can have a theory like Bohmian 
quantum mechanics in which randomness is all epistemological, like statistical 
mechanics, and there is no place for multiple-worlds.

I'm not sure what you mean by "locally".  Since they have opposite charge they 
will be attracted by photon exchanges and will fall into some hydrogen atom 
state by emission of photons.

A remark only a mathematician could make ;-)

I think Bruno just means a knot is defined by the topology of its embedding in 
space - not by its material or its coordinates; as a triangle is defined by 
having three sides, not any particular size, orientation, or material.

That would be equivalent to adding hidden variables. But then they have 
to be non local (just to address the facts, not just the theory).
Of course if the hidden factor is given by the "many worlds" or comp, 
then such non local effects has to be retrospectively expected. But 
then we have to forget the idea that substance (decomposable reality) 
exists, but numbers.

Locally yes. In QM this is given by a tensor product of the 
corresponding states. But it is an exceptional state. With comp it is 
open if such "physical state" acn ever be prepared, even locally.

Given that a theology rarely eliminates subjects/person, I don't see in 
what reasonable sense this would be a reduction.

I don't know what you mean by a physical knots. In any case the 
identity of a knots (mathematical, physical) rely in its topology, not 
in such or such cartesian picture, even the "concrete" knots I put in 
my pocket. The knots looses its identity if it is cut.

All right. But note that both String Theory and Loop Gravity (the main 
attempt to marry QM and GR) keep the quantum theory and changes the GR. 
Note that the most weird aspect of the quantum have been verified, and 
also that comp only predicts large feature of that weirdness.
(Note that QM should be completely false for coming back to aristotle, 
making QM an approximation makes its weirdness more weird).

I think it's more like asking why are we aware of 17 and other small numbers 
but no integers greater that say 10^10^20 - i.e. almost all of them.  A theory 
that just says "all integers exist" doesn't help answer that.  But if the 
integers are something we "make up" (or are hardwired by evolution) then it 
makes sense that we are only acquainted with small ones.

Isn't that like arguing that there can be no number 17 because there is no
way to assign it a measure and it would get lost among all the other objects

That doesn't follow.  The universe could be finite and closed, like the 
interval [0,1] and space could still be a continuum.

But these ideas illustrate a problem with "everything-exists".  Everything 
conceivable, i.e. not self-contradictory is so ill defined it seems impossible 
to assign any measure to it, and without a measure, something to pick out this 
rather than that, the theory is empty.  It just says what is possible is 
possible.  But if there a measure, something picks out this rather than that, 
we can ask why THAT measure?

How are you going to circumnavigate the Earth when it's intuitively flat?  
Maybe you can't arrange such a triangle for the smallest units.  The metric 
that gives x^2 + y^2 = r^2 only one possibility (and one we think doesn't apply 
near matter because of general relativity).

Bent, Stathis,

Suppose that space is discrete. It has some elementary unit. Let's call it
SU.
Suppose there are 3 of these units out there in a right triangular fashion(
L shape)
Then what is the distance between two distant angles? is it made up of some
integer numbers of space unit? Pythagoras' theorem says no. You might say we
can not measure such distance because when we're talking about elements of
space there should be nothing smaller than it... So what is that distance?

Quantum weirdness is an observed fact. We assume that it is, somehow, an
intrinsic property of subatomic particles; but perhaps there is a hidden
factor or as yet undiscovered theory which may explain it further.

You could get a neutron at high enough energies, I suppose, but I don't
think that is what you mean. Is it possible to bring a proton and an
electron appropriately together and have them just sit there next to each
other?

Yes, but if they are not operational it is not clear how they relate to our 
world of experience.  Generally they are taken to be idealized models.

No.  For example the most accurate measurement to confirm Pythogora's theorem 
now possible would be to use ultraviolet light and count the number of 
wavelengths along each side and the diagonal.  Those counts would all be 
integers.  At present this is a practical experimental limit and so one can 
imagine using shorter wavelengths and making more accurate measurements - which 
will still come out as integers.  But according to current theories of general 
relativity and quantum mechanics there is also a limit to how short the wave 
length can be; an in-principle limit.  Measurements never yield numbers that 
are not integers (or ratios of integers).

 Mathematics is just assuming some axioms and rules of inference and then

you can regard a game of chess as a mathematical theorem or even a Sherlock

Now I got it.

Only under the* *assumption that space has a Euclidean metric (*You are

Not only that, but QM admits of negative information, so some of the

comprehensive measurement.

Of course this is assuming that QM (which was discovered by applying 
reductionist methods) is the correct EXACT theory - which is extremely doubtful 
given its incompatibility with general relativity.

Mathematics is just assuming some axioms and rules of inference and then

should be consistent, i.e. not every statement should be a theorem.  So you can 
regard a game of chess as a mathematical theorem or even a Sherlock Holmes

Only under the assumption that space has a Euclidean metric - which is begging 
the question.  From the operational viewpoint, all measurements yield integers 
(in some units).  Real numbers are introduced in the Platonic realm to insure 
that some integer equations have solutions.  Similarly imaginary numbers are 
introduced to complete the algebra.  They are all our inventions - except some 
people think the integers are not.

But just comp, without the quantum, makes it implausible that an atom 
can be individuated so much that it makes sense to say it is just a 
part of the UD. And QM confirms this too. To compute the EXACT (all 
decimal) position of an electron in an hydrogen atom, soon or later you

an atom is part of the UD. It is "part" of the necessary discourse of

Not really because the knot is a topological object. Its identity is 
defined by the class of equivalence for some topological transformation 
from your 3D description. If you put the knot in your pocket so that it 
changes its 3D shape (but is not broken) then it conserve its knot 
identity which is only locally equivalent with the 3D shape. To see the 
global equivalence will be tricky, and there is no algorithm telling

OK, but then you identify reductionism with comp. I identify 
reductionism with the idea that something is entirely explainable in 
some finitary theory. From this I can explain that comp can be used to 
refute all reductionist theory of both matter and mind (and their 
relation).

I am aware it is a subtle point, but if you understand the Universal 
Dovetailer Argument (UDA) from step 1 to 8, in the version:
http://iridia.ulb.ac.be/~marchal/publications/SANE2004MARCHAL.htm
then you should, I think, understand that the idea that there is 
anything made of something, although locally true and useful for many 
practical purpose, is just wrong, globally. Even with just comp, but 
this is also entailed by the quantum empirical facts (even with the 
many-worlds view: if not they would not interfere). People can ask if 
they are not yet convinced by this. I have refer this by saying that if 
comp is true, physics is a branch of bio-psycho-theo-logy. matter 
emerges (logico-arithmetically, not "temporally") from mind and number.

You can attach a mind to a body, like children does with dolls, but you 
cannot attach a body to a mind, you can and must attach an infinity of 
"relative bodies" to a mind. "relative bodies" are only defined by 
infinity of arithmetical relationships, not by sub-bodies.

(I know this contradicts Aristotle notion of Matter, but see Plotinus 
for old platonist reasons, a priori independent of comp and QM, to 
already suspect that Aristotle was wrong).

OK, but it seems that we are using "reductionism" differently. You could say
that a hydrogen atom cannot be reduced to an electron + proton because it
exhibits behaviour not exhibited in any of its components; or you could say
that it can be reduced to an electron + proton because these two components
appropriately juxtaposed are necessary and sufficient to give rise to the
hydrogen atom. And if the atom is just a part of UD*, well, that's just
another, more impressive reduction. As for knots, can't any particular
physical knot be described in a 3D coordinate system? This is similar to
describing a particular physical circle or triangle.

Only if God issues everyone with immaterial souls at birth, so that
reproducing the material or functional structure of the brain fails to
reproduce consciousness, would I say that reductionism does not work...
unless you add the soul as an element in the reduction.

Because, assuming comp, neither matter nor mind (including perception) 
can be break up into simpler parts to be explained. That is what UDA is 
all about. First person expection (both on mind and matter) are already 
global notion relying on the whole UD*.
And empirical physics, currently quantum mechanics, confirms that 
indeed, we cannot explain matter by breaking it into parts. That is 
what "violation of bell's inequality" or more generally "quantum 
information " is all about. This has been my first "confirmation of 
comp by nature": non-locality is the easiest consequence of comp.

A good (and actually very deep) analogy is provided by the structure of 
knots (see the table of knots:

http://www.math.utoronto.ca/~drorbn/KAtlas/Knots/index.html

A knot is closed in its mathematical definition (unlike shoe tangle). 
You cannot break a knot in smaller parts, so that the whole structure 
is explained by the parts. Knots, like many topological structure, 
contains irreductible global information. The same for the notion of 
computations (and indeed those notions have deep relationship, see the 
following two impressive papers:

http://web.comlab.ox.ac.uk/oucl/work/samson.abramsky/tambook.pdf
http://arxiv.org/abs/quant-ph/0606114

I know that Derek Parfit call "comp" the reductionist view". this is a 
very misleading use of vocabulary. Comp is the simplest destroyer of 
any reductionist attempt to understand anything, not just humans.

  How could science be reductionist? Science is the art of making hypotheses 
enough clear so as to make them doubtable and eventually testable.
  My take on "reductionist" is to 'reduce' the observation to a 
boundary-enclosed "model" as our choice. It is a necessity for us, because we 
are not capable to encompass the totality and all its ramifications into our 
mind's work at once. Reduced (reductionist ) view is the way how humanity 
gathered our knowledge of the world. (Probably other animals do the same thing 
at their mind-level). 
  What I see here - and thank you, Bruno, for it, -  you are using a more 
advanced view of science than what I referred to as the conventional - 
historic, topically fragmented "sciences" of old. Where e.g. physics is based 
on the 'primitive' physical (material) worldview and  biology is what Darwin 
visualized. 
  Reductionist sciences established our technology. You use it, I use it. We 
just start to 'think' beyond it.
  *
  No scientist will ever say there is a primitive physical universe or an 
ultimate God, or anything like that. All theories are hypothetical, including 
"grandmother's one when asserting that the sun will rise tomorrow. The roots of 
our confidence in such or such theories are complex matter.
  I wish we had more of "your" scientists. Academia as a general establishment 
is not so advanced yet.

  Don't confuse science with the human approximation of it. Something quite 
interesting per se, also, but which develops itself.
  Lobian approximations of it are also rich of surprise, about "oneself".
  Now this is exactly what I mean. I would like to read a definition of 
'science' as you formulate it. Then again: how many 'scientists' have ever 
heard of a Lobian m?
  We are living here (list) in a vacuum and I was talking non-vacuum. 
  *
  "Science" or better, the scientific attitude, invites us to listen to what 
the machine can say and dream of, nowadays. How could such an invitation be 
reductionist?
  Here we go again: is the 'machine' superhuman? does it tell us things beyond 
our comprehension? How? "We" (Loeb etc.) invented and outlined it and its 
functionality. How can it be beyond those limits? 
  *
  I would say science is modesty. It is what makes faith necessary and possible.
  "Faith" in what? Not in 'hearsay', not in Alice-land, not in (really) reduced 
models of age-old worldviews. The 'supernatural' is a cop-out for the modesty 
to say:
  "I know not"  . 
  *
  With comp, when science or reason grows polynomially (in a trip from G to G* 
for example), then faith "has to" grow super-exponentially.

I'm not the best person on this list to answser, but I think the tidal
forces as you pass the event horizon of a very massive black hole would not
be enough to destroy you, since tidal forces are proportional to M/r^3 while
the Schwarzschild radius is proportional to M. Tidal forces will increase as
you approach the singularity, which is inevitable once you pass the event
horizon, but the time for this to happen is proportional to M. This refers
to your time frame: for the devil who threw you in, it would appear that you
never reach the event horizon.

Re: Evidence for the simulation argument - and Thanks and a dumb question.

2007-03-10 Thread John Mikes
Dear Jesse,
thanks for the cool and objective words.
I take it back (not what I said: I mean the topic) further. Our edifice of
physical science
is a wonderful mental construct, balanced by applied math, all on quantities
fitting the reduced models of historical observations from the hand-ax on.
Explanations grew out from all consecutive levels  of our epistemic
enrichment and served as indisputable basis for later explanations (even if
they 'corrected' them, like the more than a dozen entropies and still
counting). Assumptions make good basis for thousands of level in consecutive
build-up we still use 'atoms', 'molecules' 'gravity' 'electricity', 'photon'
etc. etc. as our basis. Then comes your judgement that one theory in this
building looks finer than another. The learned
(brainwashed) scientist-mind finds them as natural as fish the nonexistence
of water. The huge amount of knowledge blocks any naive (elementary)
scrutiny of the basics.

I do not argue with your learned examples; within the system matches are
found especially quantitative ones, visualizing our select domain and
scale-restrictions.
'Observational evidence' is a belief in our up-to-date instrumental readings
explained INTO the theoretical faith as evidence. Wilson found the
"background radiation" because he had readings they were fitable and he new
about the idea of such possibility in view of the Big Bang (- assumption -
as we believe it today in our present cosmology). Eric Lerner's book (90s?)
presented some doubts (The Big Bang Never Was (title approximate) -) I added
some more upon my feeble thinking. How many "ether"s and "phlogista" do we
still have?
We got rid of "elan vitale" - but did we really?
I do not start a crusade against conventional science and understand the
reluctance of the practitioners to accept the endangerment of their wisdom.
Reductionist thinking (science) is the only one our mind is capable of
exercising (mine included), but I feel it is time to take a breath and a
wider view to elevate from the age-old concepts to the acceptance of
something else, without paradoxes, givens, axioms, in interconnection of
them all and ready for a change. Human science went through changes over the
millennia, even fundamental ones at times, there are more to come. I
remember the time when tachyon-observation was denied as false, because they
seemed FTL and this was prohibited. Theory over observed. I do not claim
that 'my views' are the call for a future, I did not invent them, just
picked up changing views (not so few on this list) and opened my mind to let
them in. Since I was not committed to the 'old' I had no problem. I allow
myself to be wrong and argue cautiously:
you may be right, I may be wrong, but I have to see that in a view broader
than the conventional physical teaching. I don't believe today my own
'macromolecules' I made and got patented, they are good within the old
theory. I saw 'effects' and applied the 'wisdom'  to explain them without
scrutiny. They worked. Not perfectly, as all we have has flaws (e.g.
airplanes fall out from the sky, medicines fail, buildings collapse, etc.,)
but we  are very confident in our science.  Well, I am not without scrutiny.

I love assumptions: they push forward our advancement. Just do not allow
them to become facts and basis for many levels of consecutive conclusions
without a grain of salt.

Your expressions ("Most physicists believe", "they are fairly confident",
or: "general
relativity is a trustworthy theory of gravity" and I do not go into
'gravity'. nor into the words of curvature of spacetime) are carefully
chosen. Religious people talk more straightforward in their religious
argumentation.

Excuse my lengthy reply,  I enjoyed your argument.

Well, the basic assumption was more broad than that: it was that general 
relativity is a trustworthy theory of gravity. There's plenty of evidence 
that supports various predictions of GR which differ from Newtonian gravity, 
like the precession of the perihelion of Mercury's orbit, the gravitational 
lensing of light near stars and galaxies, and gravitational time dilation 
which can be measured at different altitudes on Earth (and it also needs to 
be taken into account when programming the clocks on board the orbiting GPS 
satellites). One of GR's predictions is that a sufficiently large collapsing 
star will form a black hole (another is that the universe must be either 
expanding or contracting, which lead to the Big Bang theory once redshift 
was observed). Black holes were theorized for a while, then in the last two 
decades they found observational evidence for a large number of likely black 
holes with telescopes.

Most physicists believe general relativity's predictions will cease to be 
accurate at the "Planck scale" of very short distances and times and very 
high energy densities, and that at these scales it will need to be replaced 
by a quantum theory of gravity. So although they are fairly confident that 
GR is correct about large collapsing stars forming a black hole with an 
"event horizon" and a size proportional to its mass (given by the 
'Swarzschild radius'), they think that the prediction of a singularity of 
infinite density at the center could be wrong, and that we'll need a theory 
of quantum gravity to understand what's really going on there.

Re: Evidence for the simulation argument - and Thanks and a dumb question.

2007-03-10 Thread John M
Cher Quentin,
let me paraphrase (big):

so someone had an assumption: BH. OK, everybody has the right to fantasize. 
Especially if it sounds helpful.Then  
some mathematically loaded minds calculated within this assumption with 
quantities taken from other assumptions (pardon me: quantizing within other 
models in science). 
Then someone takes the results for real and examines if it "gives" infinity - a 
good game in the assumed topic. 
Then Olala: there it is. So: call it singularity. What? the 3+th level of an 
assumption, already taken as a fact in science. 
Careful analysis can show similar 'evolution' of other fiction into scientific 
facts. 

I don't deny the usefulness of science (even if it is reductionist) I happily 
use the results and even DID contribute to it, but when it comes to 
understanding - or at least evaluate reasonability, I use Occam's COMB to 
remove the added conclusions upon assumptions.
No hard feelings, it is MY opinion, and I am absolutely no missionary.

is another question, but accepting GR as a true approximation of reality, 
singularity existence is a real question.

I would not go further than "according to what is said about them, they may

Galaxies, whatever, fall into those hypothetical BHs and who knows how much
Dark Matter (the assumed), we just "don't know" - it all may be neatly
stuffed
in and escape from the habitual description of the 'singularity' as an

I was merely pointing out that it is a problem to be explained, and Russell
has provided one explanation. As for the "if", well, we wouldn't want to get
too dogmatic about the things we discuss here, would we?

You are perhaps asking about paleopsychology, a field I don't know anything
about, if anyone does. However, I was talking about what it means to survive
rather than the process whereby survival might be ensured.

2007-03-08 Thread Mark Peaty


SP:' You wouldn't necessarily be squashed if you were inside the event 
horizon of a black hole provided that it was massive enough. Being 
inside the event horizon is not the same as being inside the singularity.'

MP: Two thoughts come to my suspicious mind.
1/   [Not far from the post-Freudian speculation :-] ... Attendance 
within the event horizon of a common or garden galactic variety black 
hole would seem to incorporate a one-way ticket *to* the singularity, 
would it not?

2/   I once heard someone on the Australian Broadcasting Corporation's 
Radio National Science Show [on every Saturday after the midday news] 
describing our universe in these terms. His point was that whatever we 
might think about what was 'beyond' the bounds of 'our' universe, 
nothing from here can escape to 'there'. As I understand it this is in 
line with Einstein's concept of the universe being closed in upon 
itself, the key cause of which is gravity, the curvature of space-time.


MP: Going off at a tangent, I have a question which is quite possibly a 
dumb question that just needs to be asked because it CAN be asked.

Preamble: The expansion of the universe, characterised by the Hubble 
Constant I believe, is usually explained non-mathematically by analogy 
with the stretching of the surface of a balloon as the balloon is 
inflated. The balloon surface is stretched uniformly, pretty much, by 
its having everywhere the same tensile strength and elasticity and by 
the force which causes the deformation being applied equally all over 
because it is the averaged effect of all the gas particles within the 
contained volume. That much makes sense, and the overall effect is to 
cause point locations on the surface of the balloon to recede from one 
another at a rate which is proportional at any given moment to the 
distance between the points, measured along the surface.

Question: Would it be mathematically equivalent, or significantly 
different,  to consider the measured change in size and in distances as 
a uniform *contraction* of the metric, ie the measuring system, rather 
than an expansion of the location, so to speak. In particular, why is it 
not feasible to consider the Big Bang and subsequent Inflationary epoch 
as being in effect a collapse?

Re: Evidence for the simulation argument - and Thanks to Russell and Stathis

2007-03-07 Thread Mark Peaty

Firstly a big thank you to Russell Standish for providing that 
incredibly succinct 'bit stream' summary of universal-dovetailer 
ontology. [Though only a vocational mathematician would seriously call 
it 'very simple' even if it does have less than 1% of Bruno's word count 
for his essay on the subject.] Having the two approaches to the problem 
at hand has allowed me to get a bit of purchase on the beasty.

Thanks also to Stathis for that simple and lovely, 'obvious', question 
from left-field. I am now convinced that, no matter what others might 
say, each number is in fact a process. Bruno referred to some kind of 
Platonia, some unspeakably not-anywhere place as the source of numbers 
and other mathematical objects or relationships. That is all well and 
good but as far as I can see - still - the numbers and other 
mathematical objects that people use are words in the strictest sense. 
They arise in human minds through inter-subjective induction, empathic 
copying [mirror neurons], interaction with the world, etc. But they are 
created anew in each brain that learns them, same as all other 
constructs. Their fantastic power comes about because they reflect - 
emulate and simulate - emergent properties of the rest of the universe.

That this happens so successfully in so many people leads me to infer 
that the underlying principle organising the human mind, just as that 
organising the Great IT, the Multiverse, what ever, is harmonic resonance.

**
Meanwhile -
SP: 'How do you know that you are the same person from moment to moment 
in ordinary life? The physical processes in your brain create 
psychological continuity; that is, you know you are the same person 
today as yesterday because you have the same sense of personal identity, 
the same memories, woke up in the same environment, and so on. It is 
necessary and sufficient for survival that these psychological factors 
are generated, but it doesn't matter how this is achieved.'

MP: Yep! I am a story! I am not like a story, I *am* a story. It is *my* 
story and I'm sticking to it, except when I find there are aspects of it 
I don't like. The problem [or a problem] is that this does not take away 
any of the intrinsic paradox of our experience. As I have said many 
times our experience is what it is like to be the portrayal of self in 
the world created within one's brain. The rendition in its details is 
effectively *about* being a person in his/her world, moment by moment. 
The experience we argue about, and other, possibly less benighted, 
persons write poetry and songs about, is simply what it is like to be 
this rendition. The primary practical paradox for each of us is that 
unless this distinction is pointed out repeatedly, we mistake the 
rendition, the story,  for the world itself. We are doomed to live ever 
like this. From the recesses of my dark corner it looks as if Bruno can 
show us conclusively that this subjective-objective distinction is an 
inherent feature of any kind of universe that we humans have any real 
hope of understanding.

and as per the first part above, I think that the answer to the binding 
question in each domain is harmonic resonance. As far as I can see it 
accounts for why the pure gasses like to form molecular pairs; there 
have been reports recently that our sense of smell relies on inter and 
intra molecular vibrations as the fundamental [pun unintended] mechanism 
for detection and recognition of minuscule amounts of thousands of 
different airborne molecules; Steven Lehar has been banging his head 
against the wall for many years trying to point out to people how 
harmonic resonance can easily explain a huge range of Gestalt type 
capabilities clearly effected within the brain; correlations of brain 
wave frequencies have been discovered marking temporally related 
activities of the hippocampus and cortical regions shown through MR 
imaging to be involved in the creation or activation of memories. And 
the list goes on.

NB: I hope that my imaginary destination in your speculation of possible 
post mortem exploits for my erstwhile sceptical soul is not a 
post-Freudian slip. I know that many of my contributions to this and 
other lists have lacked the erudite succinctness of those with greater 
talents; failure of concentration [AKA 'ADD'] has been a characteristic 
of life for me, but I think that 'awaking' to the innards of a black 
whole would do more than wonderfully concentrate the mind: concentration 
itself would become the major problem even for a ghost! =-O

So are sets of cardinality \aleph_2 or sets of cardinality
\aleph_{\aleph_0}.

On the other hand, one set of cardinality 2^\aleph_0 appears to be big
enough to explain all of observed reality.

Maybe Tegmarkism is going too far...

What about the realizability of mathematical concepts. Real numbers are

that counterpart is, it's toils the problem of uncountability.

True, and this was the sense in which I adopted it for the
paper. 

However, I think there is an even better argument. By interposing
another suitable onto function (f:{0,1}*->{0,1}* say) between the
observer and the ensemble of strings, one can make the ensemble of
bitstrings have any measure one likes.

So by composing the observer function O(x) with f(x), we can perform
the treatment for an arbitrary measure as though the we had an
observer O(f(x)) observing strings selected from a uniform measure.

In short terms, one can write "Without loss of generality, assume a
uniform measure over the strings".

Whichever way you cut it, structure is still in the eye of the
observer :)

If a uniform measure leads to the world we see, isn't that empirical
evidence that it is the correct one? A uniform measure, or no measure at all
(which seems to me equivalent), isn't really as arbitrary as some specific
measure from physics, which as you imply is what the whole everything idea
is trying to avoid. Could the question in theory be settled by experiment,
running the UD and counting the relative number of structures?

The basic problem I have with this proposal is the starting assumption, 
where you say that the "natural measure induced on the ensemble of bitstring 
is the uniform one." This sort of assumption is made by a number of TOEs 
including Schidhuber's, but it always seemed fairly arbitrary to me, not

Well there is a reason we don't observe them, due to observational
selection effects tied to Occam's razor. This is written up in my "Why
Occams Razor" paper. Nobody has shot down the argument yet, in spite
of it being around on this list since 1999, and in spite of it being
published since 2004.

You survive if a sufficiently close analogue of your mind survives. This can
theoretically happen in many ways other than the obvious one (survival of
your physical body): in parallel worlds, in a distant part of our own world
if it is infinite in extent, in the Turing machine at the end of time. The
white rabbit universes are a problem: since we don't observe them, maybe
these theories are wrong, or maybe there is some other reason why we don't
observe them.

How so?  The Many Worlds idea seems to imply that you survive no matter what. 
The consequences of natural selection obtain only within worlds which are 
law-like - and we're back to the white rabbit problem.

How do you know that you are the same person from moment to moment in
ordinary life? The physical processes in your brain create psychological
continuity; that is, you know you are the same person today as yesterday
because you have the same sense of personal identity, the same memories,
woke up in the same environment, and so on. It is necessary and sufficient
for survival that these psychological factors are generated, but it doesn't
matter how this is achieved. If you suddenly die today and are miraculously
recreated inside the event horizon of a black hole, no-one will ever be able
to find you again but you will be able to find yourself.

Re: Evidence for the simulation argument

2007-03-06 Thread Mark Peaty


Thank you Bruno!

You and Russell between you have managed to strike some sparks of 
illumination from the rocky inside of my skull. There is no beacon fire 
to report but I start to get a glimmering of why you want to *assume* 
comp and see where it leads.

It seems that self-reference and recursion are fundamental properties of 
anything that is "interesting" in all this, which rather seems to be the 
flavour of the new millennium.

Just in thinking superficially about the Many Worlds though, it seems to 
pose a 'binding problem'. Now, I know that might sound like a leakage of 
concept from objections to identity theory in brain and mind theory. But 
what I am thinking about is this bit:

6) this means that if I take the comp hyp seriously, then, to predict 
the results of any experiment/experience, I have to "localize" all the 
infinitely many instantiations of my current state in the UD, look at 
the uncountable comp histories going through that states, and compute 
the statistics bearing on all consistent first person 
self-continuation.

 A human life must be a compilation of all these including the creation 
of internal [synaptic change, etc] structure/record which endow the 
ability to *be* the story. But when looking at this as a/n 
[infinity^infinity] Many Worlds affair, none of the worlds could 'know' 
that they are like or identical to others, surely? So I am puzzled. What 
holds 'my lot' together? We seem always to be confronted by yet another 
infinite regression.

**
A quick aside, hopefully not totally unrelated: Am I right that a valid 
explanation of the zero point energy is that it is impossible *in 
principle* to  measure the state of something and therefore *we* must 
acknowledge the indeterminacy and so must everything else which exists 
because we are nothing special, except we think we know we are here, and 
if we are bound by quantum indeterminacy, so is everything else [unless 
it can come up with a good excuse!]?

[Perhaps this is more on Stathis's question to Russell: Is a real number 
an infinite process?]

All actual measurements yield rational values.  Using real numbers in the 
equations of physics is probably merely a convenience (since calculus is easier 
than finite differences).  There is no evidence that defining an instantaneous 
state requires uncountable information.

Re: Evidence for the simulation argument

2007-03-05 Thread Mohsen Ravanbakhsh
Thank you for welcoming me Mark,
I agree with you about the problem with the concept of entropy, but not all
your points. Actually I like this hypothesis, and as Bruno put it we might
be able to describe the Why question about physical laws, which is very
interesting.


4) There exist a universal dovetailer (consequence of Church thesis,
but we could drop Church thesis and define comp in term of turing
machine instead).

5) Never underestimate the dumbness of the universal dovetailer: not
only it generates all computational histories, but it generates them
all infinitely often, + all variations, + all "real" oracles (and those
oracles are uncountable).

Let me know where's my mistake:

1.We are referring to one (actually an infinitely long sub-sequence of that)
history of such universal dovetailer, as some state of our world.

2.Because that machine is a TM, a history has to be countable, regardless of
compression or expansion of time to allow infinite power.

3.So we're referring to some state of our universe as a countable one.

4.A universal state is not countable.

Every time a bit is sampled, the Multiverse branches
with the observed bit being 0 or 1 depending on your branch. If you
were to continue for an infinite amount of time, each observer will
have observed a real number. However after any finite amount of time,
all the observers have are rational approximations to real numbers.

But we're talking about uncountability of information necessary to represent
instantaneous state of a universe, not about the uncountability of possible
universes. (Maybe I didn't get your point)
What you are saying just proves that we have uncountable number of
universes.
