They are math! It is the game I play. I like very much David Deutsch's
idea that if we are scientist we are in principle willing to know that
our theory is wrong, but to discover this we have to take them
seriously enough.

Nobody can KNOW that. The fact is that ONCE you take the comp hyp
seriously enough into consideration, then you can, by work, be
eventually convince that our own immateriality (which follows easily by
comp) has to be "contagious" on our possible neighborhoods.

yes sure. But we are not talking about those numbers humans
(re)invented, but on those which have to exist independently of us once
we accept some minimal amount of computer science, without which we
could infer nothing fron comp (our, well mine, working hypothesis).
> as David Bohm so clearly stated.
No problem, Bohm is a serious guy, he makes clear he does not accept
the comp hyp at the start. Bohm is serious, and as far as I can jujudge
by my reding, he is 100% correct. But he denies comp.

You could be right. The point we are addressing is the question of
making our hypotheses clear enough so that we can refute them or make
sense of how we could have them refuted at least in principle.

All proof in math are particular case of thought experiments. In
philosophy-of-mind, theology, theoretical physics and math, the only
tools available are the thought experiments.

I totally agree with you here!

We have no proof that the earth is round, only solid evidence that the
roundity of earth is a solid *local* truth.

Imo, Rosen is wrong on Church thesis. But this could wait when I
succeed to explain more about CT later ...

Just keep track of the definitions. By angels and gods (note the
plural) I mean things which are not turing-emulable, or if you prefer,
any entities which are provably not machines.

I am a realist. I guess there is something more than me. The rest, the,
can be justified as first person points of view.

What is conventional sciences. If by this you mean that sometimes the
academy gives grades and honours wrongly, then you are right but this
is really "human too much human" as Nietzche said once. We have no
choice to learn with this facts. I prefer to talk about science, and
describe some science has being wrong from time to time (like when Bohr
dismissed Everett, just because what Everett said contradicted his
(Bohr) wishfull thinking. Science = doubt and modesty. When scientist
pretend to know the truth, they are mad, that's all.

Nor do I believe in the primary nature of those notion. Plotinus (+300)
did already understand that such notions were inconsistent with the
more primitive platonic ideas. Now, I could accept that atoms (the
modern one), like the spherical hypothesis about the earth are
excellent local theories.

I can agree. But still, without taking those ideas seriously enough, we
will never know them wrong. Science is really the ability to be wrong
in a way as clear as possible; so you can hope to know being wrong soon
enough.

Not necessarily, and it depends what you mean by "model".

I have read it, I think, quite a time ago. Please gives a link, so that
I can reread it.

No serious scientist will ever try to convince others (except for the
mundane purpose of getting some funds). As I said a scientist, not only
does not want to convince others, he want others to show him wrong
instead. You confuse scientists, and mediatico-pseudo-scientists, which
can exist still today due to 1500 years of abandon of the fundamental
question to political pseudo-religious authorities. Of course they have
had no choice, because it is best to do pseudo-science than to burn
alive ... (I don't judge them here).
> I offer them for consideration - period.

Don't be sorry, I like to chat on those questions, as you know, and it
gives us some opportunities to clarify (or not) ourselves. Key point
here for me: science = doubt = modesty= acknowledgment of ignorance =
lack of any communicable certainty = questions sharing (never
"definitive answers" sharing).
