Probability is a mathematical model. It can be used to model events
where we are ignorant of the causes, although we assume they exist.
That's how it was invented, by game players. But it isn't necessary to
assume there are unknown causes. The same model then describes inherent
randomness.

It's convenient model of measurement in quantum mechanics to avoid the
question of why measurements need to be described by a physical process
(projection) different from all other physical processes (unitary
evolution by the Hamiltonian). Whether such worlds are "real" is
controversial.

In physics, things can only affect events in their future light cone and
events are only affected by events in their past light cone. There are
some theories, such as Bohm's quantum mechanics, which violate this

This can't be right, if we assume that the brain (or whatever capable
of sustaining consciousness) can be emulated by a Turing machine, as
most people believe.

A determinist theory of free will is possible. What counts is that no
machine can determine itself completely, so that the determinism of
his/her behavior is known only by "God", not by the machine, nor by
machine of equivalent complexity.
Now, if you mean that free will is the capacity to disobey to
arithmetic, then it does not exist, most probably.
> why is there binary state at all ?
OK. You could have asked equivalently: why is there natural numbers?
Logicians have shown last century that this is impossible to answer.
Actually we need the natural numbers to ask "why natural numbers".
They cannot be recover from any simpler theory. So we have to have
some faith in them. It is part of the initial postulates.
> if there is free will,how can we say everything affects everything ?
> why is the 50-50 probability arises ?
Such a probability can be explained by self-duplication. If you are a
machine, I can scan you (in principle) and duplicate you in two
different places. You cannot predict in advance what will be your
subjective experience after the duplication. BTW, this can be used to
explain that free-will is not explainable by the use of indeterminacy.
> why is there probability functions at all ?
Assuming we are digital machines, the answer is that the reality of
realities is very huge. There is an infinity of computations going
through your actual state of mind, and computer science explains why
no machine can know which computations, nor even which sheaf of
computations support it. There is automatically a statistics for the
observable.

> you don't have a free will ?
Why? On the contrary. To have free will you must have some ability to
make change around you. You certainly need some amount of determinacy.
> Is our consciousness part of the grand consciousness (the universe).
If by universe you mean "physical universe", it is not clear if that
exist. Strictly speaking it is an open problem. With mechanism we can
say that there are many dreams, and we can say that some dreams glue
well together to form shared dreams. But it is not known if they glue
so well as to define a singular physical universe, or even just a
singular physical multiverse. Extremely hard question.
> Are we like the white cells(individually conscious) in our body,to the
> universe..?
You might be naive about "we", "body" and "universe". No problem, it
is a tradition since theology has been abandon to politics 1500 years
ago, in Occident. (Closure of Plato Academy in Athena, about 525 after
JC).
> Then above all,the real question is why is there parallel worlds at
> all ?
If you accept the idea that your brain can be simulated at some
correct level of substitution (so that you would survive a digital
brain substitution), then the additive and multiplicative structure of
numbers defines a vast "block mindscape", containing many dreams (as
seen from inside). Some dreams glue and generate sharable (among
collectivities of "universal numbers) deep histories, which are seen
as universe appearance from their points views. The physical realm
does not disappear, but is secondary to the "numbers dreams". The
physical realm is still fundamental, but it is epistemological, not
ontological.
You might read the shortest paper(*) I wrote to sum up the
consequences of taking seriously the *assumption* that we are Turing
emulable. We discussed it a lot. Some have not yet seen the point, I'm
afraid. I sum up it provocatively sometimes by saying that if we are
rational machine, then we have to abandon the theology of Aristotle
(atheism christianism etc.) for the theology of Plato (objective
idealism, Pythagorism, some budhist and indian school or thought). In
the first one there is an emphasis on the 'creation'. In the second
one the creation is a sign of something else (actually arithmetic).

> everything affects everything or not ?
In which sense? In our local physical realm even a big supernova
explosion far away, cannot affect you here and now.
In the arithmetical realm every truth is connected, but perhaps in a
more trivial sense. They are infinities of intermediate modalities.
Take it easy. We are in deep water. Ask any question.
Bruno
I appreciate Nicolas Gisin, like I appreciate a lot Conway and Kochen,
but they have in common that once they talk on free will they utter
non sense. I will probably read Gisin's paper, but I have not really
the time right now.
Let me says tell you why I doubt on the interest on this, from reading
just the abstract: the MWI has been invented notably for making
physics local, as Everett and Tipler have already explained, and as
Deutsch and Hayden have made even more clear. So I guess there is
either an error in Gisin, or that he has made a very interesting
discovery. But I doubt, especially that he might have a non
compatibilist theory of free will, which makes almost non sense for
me. You have already to postulate non-comp to get it. Hmm...
Of course if the goal is to make money, that can be a road. People
like wishful non-sense. But you might make more money with astrology
or with pseudo-religion.

Did you see "The Sting" (1973, Paul Newman and Robert Redford)?
I think that something like that is possible coupling Renninger's paradox
(null measurement) and MWI. Not so easy though.

Hi Scerir and Friends,���� Thank you for posting this link to N. Gisin�s paper. In it Gisin makes a very eloquent and forceful argument against MWI based on the experience of free will.
�
You can find a talk that he gave on the subject here: http://www.youtube.com/watch?v=9WnV7zUR9UA
����� I think that Gisin's argument is stunted by the fact that he does not consider the effects of multiple entities having free will and instead only considers a single entity having free will in the MWI picture. His point in the paper that "if a specific interaction with one possible state of affair produce a desired effect, this very same specific interaction with most of the other - equally real according to many-worlds - state of affairs would produce uncontrolled random effects. Hence, it seems that there is no way to maintain a possible window for free will in the many-worlds view" is correct but the "uncontrolled randomness" is only random because we can only resort to an equiprobable ensemble to do calculations of the effects of the interaction in that context.��� If we consider multiple observers within the MWI, it seems to me that in order for some measure of coherent communications to obtain between them there must be something like a super-selection rule on the branches of the superpositions such that only those mutually compatible observables are able to form a set of mutually true (in the bivalent Boolean sense) in the sense of relative commutativity of observables on each time-like (not just space-like) hypersurface of a foliation of space-time for those observers. I think that this is something that decoherence is pointing toward.���� Free will follows from the lack of a priori determinateness of the members of that set of observables. Just as we cannot demonstrate a computation that can compute whether or not a given computation will halt, we can similarly not demonstrate a finite Cauchy hypersurface of initial conditions that can uniquely determine both the order of measurements nor the mutual results of those measurements.

Offered without comment. I just thought it was interesting:
==
What kind of a theory might it be that determines these choices? Many
people who are unhappy with computationalism would be just as unhappy
with any other type of mathematical scheme for determining them. For
they might argue that it is here that "free will" makes its entry, and
they would be unhappy that their free-will choices could be determined
by any kind of mathematics. My own view would be to wait and see what
kind of non-computable scheme ultimately emerges. Perhaps a
sophisticated enough mathematical scheme will turn out not to be so
incompatible with our (feelings of) free will. However, McCarthy takes
the view that I am "quite confused" about free will, and that my ideas
are "not repairable". I am not really clear about which of my confused
ideas McCarthy is referring to. In Shadows, I did not say much about
the issue of free will, except to raise certain issues. Indeed, I am
not at all sure what my views on the subject actually are. Perhaps
that means that I am confused, but I do not see that these ideas are
remotely well enough defined to be irreparable!

Why. It looks to me I need numbers to distinguish object, even to

Why? I got the ffeliong that you assume a primitive physical reality.
I do not. (nor do I assume there is no such physical reality). But I

It does not. If my body is a machine, then neither mind nor matter are
completely mathematical (unless you enlarge the sense of mathematics).
The main point is that neither mind, nor matter are primitively
physical. I just show that mechanism does not solve the mind-body
problem per se, but on the contrary that it can help going to a
mathematical formulation of the problem.

Have you study the UD Argument? It shows that if we assume that the
brain works like a universal machine at some description level, then
Aristotle theology get falsified. Not Plato's one.
I am a logician. I don't try to find some truth. I just show that if
you believe in this theory, then you have to believe in that theory. I
assume a minimal amount of rationality, which is made eventually
precise.
And yes, I do argue that comp, (not me) resurrect Plato and Plotinus.
I provide a clear arithmetical interpretation of those discourses. You
might take a look on my paper on Plotinus (on my url front page).
