                    I would go further and say one cannot disbelieve in God

                    You can easily know that things with self contradictory
                    properties are not in reality.


                I agree with that.

                    If something has properties that are inconsistent with
                    observation that is fairly strong evidence it doesn't exist.

                    "Either God wants to abolish evil and cannot; or he can, but
                    does not want to; or he cannot, and does not want to.  If he
                    wants to, but cannot, he is impotent. If he can, but does 
not
                    want to, he is wicked.  If he neither can, nor wants to, he 
is
                    both powerless and wicked. But if God can abolish evil, and 
wants
                    to, then how comes evil in the world?'"
                          --- Epicurus


                That's a nice example of an application of rational thought 
towards
                the advancement of theology. You've proven that an omnipotent 
God
                with the power and desire to prevent any bad thing from 
happening
                does not exist.

                What else might we have been able to prove or disprove if 
theology
                had remained open to free inquiry over the past several 
millennia?


                    And then there are things that are consistent with both 
logic
                    and observation, but are very unlikely on our best theories 
of
                    how the world works, e.g. teapots orbiting Jupiter.  Are you
                    "agnostic" about the teapot orbiting Jupiter?


                To disbelieve in a particular thing orbiting Jupiter requires a
                working theory of our solar system.

                To disbelieve in a particular thing existing at all (neither in 
this
                universe, nor in any other place in reality) requires a working
                theory of reality. What is yours?

                    Does "agnostic" just mean "I don't know for certain" or 
does it
                    mean "I'm equally disposed to believe or disbelieve." or "I
                    think it's impossible to decide the question."


                That's a good question. I think a definitive answer can be drawn
                from one's working theory of reality, but I don't know if an 
answer
                to that question is decidable or not, though perhaps it's 
possible
                to accumulate evidence towards one. So far I think man has made
                little progress in this endeavor, but Bruno and Tegmark seem to 
be
                farther ahead than most towards developing one. Working under 
those
                theories, I might say I am more of a "rational theist" in the 
sense
                that I can identify at least three things one might call god 
within
                those ontologies. However, as to which theory of reality is 
correct,
                I might call myself agnostic (even though I might be in the high
                90's percentage wise leaning towards it, I could never be 
certain).




                        Personally I don't disbelieve in God, I merely find the
                        idea highly unlikely


                    Why do you find it highly unlikely (what is the conception 
you
                    are assuming here?),

                    When I write "God" with caps, I mean a god who is a
                    superpowerful person and who wants to be worshipped; not 
some
                    abstract organizing principle or the set of true 
propositions.


                Subtract "and who wants to be worshiped" then re-answer that
                question.  Why should we suppose that super-powerful minds are 
not
                likely to exist in reality?

                There's a difference between "super-powerful minds" and "a
                superpowerful person".  By superpowerful person I meant one who 
could
                transcend physical laws, i.e. perform miracles.



            A super powerful mind (or person) simulating some reality could of 
course
            cause the simulation to deviate from its "physical laws".

            But in a simulation, not in reality.


        The simulation is as much "reality" to those in the simulation as our 
reality
        is to us, to the point where it's impossible for anyone to know whether
        they're in a simulation or not.

                By the very definition of miracles these are not reliably 
observed
                and so the empirical evidence makes their existence very 
unlikely.


            You could only draw this conclusion if you believed it highly 
likely that
            should any miracle have occurred in this universe, humankind would 
have
            observed it.

            No, I only have to assume that human observations are a fair sample 
of the
            world I'm trying to draw conclusions about. Since this is the world 
that
            humans experience, that condition is fulfilled.

            This alone would be highly dubious given how small an extent in 
time and
            space (compared to the universe as a whole) humanity has kept 
reliable
            records.

            You seem to think one needs to have positive evidence against every
            alternative theory in order to believe one theory is more likely 
than the
            alternatives.


        I was only pointing out that lack of evidence is not evidence to the 
contrary
        unless it is likely that evidence would exist given the range of 
observations
        collected. Is our lack of observance of alien life evidence strong 
against
        alien life in this universe? Certainly not, since we're only familiar 
with an
        infinitesimal part of the universe and have only been watching the 
skies for a
        very short time. It's also arguable that interventions in the physical 
world
        would be undetectable, since if the universe could be wholesale 
modified, it
        might as well be modified into a consistent way such that the 
modification
        appeared consistent.


                A superpowerful mind might just be a human mind implemented in 
an
                electronic medium so that it was millions of times faster - but 
was
                still a Turing machine.  It couldn't do miracles.


            It could for the beings within the realities it simulates / 
instantiates.

            So I can do miracles too because I can write simulations - thus 
draining
            "miracle" of all meaning.



        You would also be a theistic God to those creatures inside your 
simulation.
        Hopefully you would be a good one.



                    also, to what degree do you hold the main idea the 
everything
                    list is meant to discuss, to be true (or likely)?

                    I'm evenly divided on that question.


                So then would you not also be evenly divided on the existence of
                "superpoweful people who want to be worshipped"

                No, see above on "superpowerful people".


            See above on realities simulated by super-powerful people.


                (assuming the two are not mutually exclusive properties and 
hence
                not logically impossible) then if every possible universe 
exists,
                some are sure to contain "superpoweful people who want to be
                worshipped".


                        and don't find that it contributes anything to 
discussions
                        such as "why is there something rather than nothing?"


                    But "god" is the supposed answer to that very question.

                    "God" is also supposed to answer the question, "How should
                    humans behave?"


                Yes, and the conception of God as the one mind to which we are 
all a
                part does provide a foundation for an ethical framework (not 
unlike
                the golden rule or karma).

                Yes, and the conception of God as a tyrannical patriarch 
dictating
                behavior also provides a framework for ethics - one that has 
been
                widely employed. Does that prove that both concepts of God are 
realized?


            No. That is what theology is for.


                    and "Who will save me from death or disaster?"


                The conception of God-like entities with the power to
                computationally simulate worlds and galaxies can "save you" by
                providing you a computational afterlife.

                And providing they exist and that "I" can experience it.


            By arithmetical realism they exist, and by computationalism you can

            That's the speculation of Bruno's theory.


        It's also presently the leading theory of mind, and for good reason.

              But why should I assume arithmetical realism,


        Because 2+2=4, and there's nothing you (or anyone/anything) can do to 
change that.

        Sure there is.  2+2=0 in mod 4 arithmetic - which is good for 
describing some
        things.


    Very clever, but you get my point. Try to make 7 a composite.



            and why should I identify mathematical proof with belief?


        I don't know that you should.



                    The question is not is there an answer or isn't there (of
                    course there is since we are here),

                    That doesn't follow. Conceivably there is no "reason".


                Only in an fundamentally non-deterministic universe, which I
                personally have great difficulty conceiving.

                I don't.  The current, best theory of this universe is 
non-deterministic.


            It's not fundamentally non-deterministic, only apparently so (and 
this
            was explained by Everett, who provided the only mathematical and 
complete
            theory of QM and the illusion of collapse).

            Everett explained that other universes split off, but it's not 
entirely
            clear what this means. And it leaves the universe of which we are
            conscious as indeterministic.


        I have no conceptual problem with subjective non-determinacy.

        But you think a simulation is just a different reality, so you should 
have no
        problem with objective non-determinancy  since it can be produced in a 
simulation.


    My only problem was with fundamental non-determinism.

    So now you're going to draw a distinction between simulation and reality; 
the former
    isn't fundamental.


That's interesting. If its true that fundamental randomness does not exist in reality, then detecting it would be a clear sign that one is in a simulation. But this presupposes that one has access to all information about the simulation from within the simulation. Perhaps that is true of our physics, but it wouldn't be true of a hidden-variables type theory.




                    In the major religions the "reason" is that a supernatural
                    immortal person willed or caused it. "Reason" referred to 
what
                    humans mean when they ask one another for a reason. Physical
                    causes are not reasons in that sense (although Aristotle 
thought
                    they were).

                    the question is what is the nature, and what are the
                    properties, of that thing,

                    Now you assume it's a thing or object. Are the equations of
                    quantum field theory a thing?


                Yes, but are they the ultimate explanation for their own 
existence
                or not?

                I don't think existence needs an explanation.


            It sounds like you've given up on that line of inquiry.

            It seems that any explanation of existence is either going to be 
circular
            (which I like) or an infinite regress or non-existent.


        You left out: first-cause(s) -- a self-existent thing which accounts 
for both
        its own existence and other things which follow from it.

        But that's a cop-out.  If something can be self-existent then it might 
as well
        be the universe.


    But not necessarily. The universe might be derivative of something else 
which is
    self-existent.

    Sure.  But it might not be.  So there's no logical inference to "something 
else".


Perhaps not a logical reason, but physics might prove that the physical universe could not have bootstrapped itself. I don't know that we disagree here.



          If everything needs an explanation then the putative "first-cause" 
needs one
        too (unless you want to give up that line of inquiry).


    A first-cause can have an explanation, just not a cause. For example, I 
find the
    existence of computations as a consequence of self-existent mathematical 
truth to
    be an explanation, but one concerning something which has no cause.

    OK, what's your explanation of mathematical truths.


I believe mathematical truths are sufficiently stable and independent of everything else (nothing else can change them, so they are changeless, so if they are what they are now, they've always been, and the introduction of a physical universe changed nothing about them (since they're changeless)) that this explains why they are self-existent and not in a need of any cause.

But that's true of all mathematical truths (exp(i*pi)=-1) and all logical truths (X and Y => X) and all analytic truths ("unicorns have one horn"). Isn't it easier to suppose these truths are about relations between concepts and that's why they are changeless and there's no reason to suppose they exist.

    And how do mathematical truths cause anything?


They contain programmatic executions of digital universes, brains, minds, dreams, etc, which provide the illusions of life within a physical universe for many of those minds.

If the are illusions, what are they illusions OF? Have you switched again and now suppose that simulations are the same as real?






                What part do those equations play in the relation to everything 
else
                that may exist?

                They are constraining descriptions we invented.



            But do they describe everything that can exist, or might they only
            describe the reality in which we are embedded?

            Of course we invent descriptions to fit what we observe.  Any other
            "reality" is speculative.


        All theories in science are speculative,

        But they propose to describe the same reality, the one that is the 
object of
        subjective agreement.


    Only according to the other figments of your imagination ;-)

    Including you.  "Intersubjective agreement" is the only operational 
definition of
    "objective" that I'm aware of.


I consider "objective" to refer to the non-subjective. Thus an objective fact would remain true even if there were no subjects to appreciate it.

I think you need to distinguish what theories say about the world and observational facts. That dinosaurs roamed the Earth is part of a theory, a very well supported one, and if the theory is true "dinosaurs roamed the Earth" expresses an objective fact by your definition. I wouldn't call it a fact though because it is too far removed from observation that can be checked by others. Of course nothing is a pure fact in this sense; even the existence of other people depends on a theory. But it's still useful keep "facts" close to what we are empirically more sure of than the theories we infer from them.
