I don't think any of us qualify since you have to believe and be aware of your belief of 
every tautology which means all possible mathematical proofs.


Actually it seems to me that so much self awareness is contrary to the common notion of 
'free will'.  The feeling of 'free will' comes about because not only or our decisions 
unpredictable, they are unpredictable even by us.  If you had really complete 
self-awareness you could trace your every decision back to various external inputs or 
random events and you would be disabused of the feeling that "I could have done otherwise".

FREE means being *able *to choose *any *among a number of choices.  You
want freedom of will to mean an agent can choose something beyond what the
given choices are?  That would imply free will does not exist yet, in that
event, free will is still NOT meaningless.

Right now I am unconcerned with whether free will exists or not.  I am
concerned with the statement ""free will" is meaningless."  I have given a
definition, borrowed from the SEP, that is as good a definition as for any
concept (outside mathematical ones).

There are aspects of the soul theory that are comprehensible, in fact there
are aspects about it that I think are true, but a much better name for it
would be "information". What I think is gibberish is "free will", it is

The God theory is not gibberish, it's just wrong. Free will is not even
wrong. And they got null results only when the sick people didn't know they

I'm not saying that though. We *are* the physical changes. Third
person and first person seem to us to be separate because the first
person end is the 'head' end. You are saying that I think 'whatever it
that is our head leads to physical changes which manifest as our tail'
and you are trying to get me to see that it makes more sense to say
that it is our tail which is responsible for the existence of the head
- that the head is what the tail needs to lead it to food and
reproduction. That's not my position though. I'm saying head-tail mind-
body are a function of the symmetry of sense.

As far as fields being detectable - detectable by what? I have no
problem detecting humor, irony, style, beauty...to a human being these
are detectable energy fields, only higher up on the monochord/chakra-
like escalator of qualitative interiority/significance. The universe
for us is much more readily detectable by us as a combination of
fiction and fact than it is in terms of matter/energy/fields. Those
things are a posteriori ideas about the universe of our body, as
verified by consensus of inanimate objects interacting. That is only
half of the universe - the tail half which is the polar opposite of
awareness. It is the perspective from which no life, order, meaning or
significance can be detected.

I do say it's physical. Physical feelings, physical stories, physical
personalities and identities - all physical, but not as objects in
space, as experiences through time. There is no mechanism that
mediates spacetime-matter-energy with timespace-sense-motive, they are
the same thing except the more something is you or is like you, the
more it seems to you like the latter instead of the former.

The 'mechanism' is sense. It doesn't conform to laws but it develops
habits which become as laws to those who arise out of them. It's only
a mechanism when the insider looks outside. What we are doing now is
looking outside as the insider's exterior and finding it lacking any
trace of the insider, concluding that the insider is an illusion. When
the insider looks inside however, there is more animism than
mechanism. Sense experience and meaning. On the outside, the nerves
are literal fibers and cells. On the inside 'nerve' is strength,
courage, self-legitimizing ontology. They are part of the same thing
but don't correlate one-to-one, they correlate as the whole history
and potential future of the universe twisting orthogonally into an
event horizon of a whole universe of 'here and now'

Exactly, they are not separate except to the participant. We are the
head looking at our tail, but objectively, if we were not a head, we
would see both head and tail are the body with two ends, each being
everything that the other is not. If there were rules, then the rules
would need rules. What makes the rules? Where to they come from and
what mechanism do they use to rule?

As you say, and we agree, the interaction must be two way, but no
external rules are required to govern the interaction, because both
mind and body are, on one level, the same thing (essentially)

Does a Free Willer believe they willed themselves into existence in

Some can believe that. Open question in comp. Actually "this  
universe"

is a quite vague concept with comp.


Don't know comp.


comp is the idea that we are (a priori material or natural) machine.  
It the old mechanism of Descartes, without the dualism.


But it leads to the fact that matter and nature exists only in  
number's dream (that computation in arithmetic seen from the first  
person point of view). See my papers for the argument, or read my  
recent conversation with Charles and LizR).




As far as I'm concerned, universe can be everything,
all permutations.
I don't believe there is a mind separate from body. You don't have a
mind (or a soul,
or whatever metaphysical description of consciousness one might
subscribe to) until
you have the matter and energy arranged to form the mind.


That's locally true for the human mind, but globally false. Matter  
emerges from the interference of the many computations/dream occuring  
in arithmetic.




I know
matter is a mental
concept but yeah, whatever makes up the calculation of that stuff we
perceive as
matter and energy.


Computer is a mathematical notion, even arithmetical. Once you accept  
elementary arithmetic, all computations are there, and it makes  
arithmetic a realm of everything (even a tiny part of arithmetic  
actually).


Advantage: it explains where the laws of physics come from, and it  
gives the mean to distinguish quanta and qulaia, and explain the  
difference of their nature.





When that comes together, you have a mind, and at
some point
that mind develops a will, but not the other way around.


OK.






They seem to think this free will has some ability to manipulate the
Universe in ways that avoid it's laws.


Not the compatibilist one. I think free will is not prevented at all
by determinism.


I agree, will (free has no meaning to me) is enabled by determinism.
If there were no
process of cause/effect then there could be no calculation of will.




I don't believe I willed myself into existence. I cannot will myself
to avoid the end of my existence.


If that exists. Again "my existence" is quite a vague notion.


Basically I'm saying existence is needed before a will can exist, not
the other way around.


Yes. But with comp we need only the existence in the same sense as  
"prime numbers exist". We don't need and actually cannot use the  
hypothesis of existence of primary matter (Aristotle).




You have to build the computer before you can execute a program, not
the other way around.


Computer are just relative universal number (I am explaining this  
currently in other thread).







While I'm here I cannot break any of
the laws of the Universe. We are all molecular machines.


Locally, that is very plausible, but near death, this is no more
assured unless you introduce actual infinities in bith matter and
mind, and some link between. We are not bodies, we own bodies.
Molecules are clothes, and actually they are map of our most probable
computations in arithmetic. This is a consequence of the idea that  
"we
are machines". It makes materialism wrong eventually. Matter is a  
mind

construction.


We are the program which does not exist without the machine
(computer).


OK.







Those
molecules operate within the laws of the Universe.


If that exists. Locally, it is true, but not globally.


Locally and currently, yes, I understand.




The result of their
action allows me to think and reason and decide on a course of  
action,

execute a will so to speak, but that will is determined by the
sequence of events of the molecules that make up my self. To say  
"free

will" implies that I somehow avoided the laws of the Universe and
resulting cause and effect. "Free" from the laws of the Universe. In
that sense, there is no such thing as "free will", only "will", that
is determined by your physical being and sequence of molecular  
action.


OK. Locally.




Now I myself believe that probably the laws of the Universe allow it
to be non-deterministic. My logic might be simple on this, but if
there were no randomness at all, there could be no evolution of the
Universe (and probably the laws of the Universe) to become the
Universe we observe today. I think if we started (over and over  
again)

with the same initial condition of this moment, that the next moment
could be any number of potential outcomes, all within the same  
laws of
the same Universe. The Universe is built upon the laws of  
probability,

and at the short term macro level things can be fairly predictable,
but at the micro level and over long periods of time, things are not
so predictable, due to random events at the quantum level. I also
subscribe to the idea that all possible outcomes exist  
simultaneously

and forever, as do all possible histories.


OK. But with different probabilities, and we can manage them from
ins

The question before he enters the box is, "Will you find yourself on

The question is about your future subjective feeling as seen from your  
future first person perspective. If you assume comp, you know in

Mars, and you know that you cannot that in advance (or give me the
