I don't know what you're trying to get at with soul = intellect.  To 
me the intellect is simply at the same par with provability and 
reason.  The intellect has to be given true truth in order for it to 
come up with true truth (if it reasons consistently).  More than that, 
the intellect has to be given true truth and know that it was given 
true truth, in order to reason its way to more true truth and know 
that it has done so.


To sum up with logician's tools: G* can prove that Bp and Bp  p are 
equivalent (p representing any proposition written in some language 
understandable by the machine, for example numbers and addition + 
multiplication symbols in case the machine is a  Peano Arithmetic 
prover. Godel showed how to define the provability B with numbers and 
addition and multplication symbols and Penao axioms indeed).
With the Plotinian vocabulary: The divine intellect know that the soul 
and the intellect are the same machine having the same discourse, but 
neither the soul nor the intellect can know of believe that, so that 
they differ from their point of view.
You can guess (unlike Plotinus) some inescapable tension between the 
soul and the intellect. The intellect is the humble and modest one. It 
is a scientist. The intellect is aware that either he can say  
crackpots-thing or it is consistent that he will say crackpots things 
(cf ~Bf - ~B(~Bf) is equivalent with Bf v DBf). On the contrary, the 
soul looks a bit like an arrogant entity which never doubt, which 
pretend to be always right and, the more unnerving, is always right. 
Now with the sound machine, the divine intellect know that the soul and 
the intellect (terrestrial) have the same discourse, but neither the 
soul nor the terrestrial intellect can ever believe or know that 
assimilation.

My reasoning will work already with arithmetical truth. This is non 
trivial. Leibnitz, Hilbert, and many mathematicians before Godel would 
have believed that arithmetical truth gives a narrower model, but after 
Godel we know that we cannot formalized that notion in any effective 
way. The fashion today consists even in considering it to be a too 
large concept.
But I will make clear (well I will try, or refer to some literature)  
that what I say can be extended on much more large notion of truth.
I assure you John that the approach is everything but reductionnist. 
Even just about numbers there is no effective TOE (by Godel).
Now, there are angel like Anomega (Analysis + Omega rule) which can 
grasp the whole arithmetical truth, thanks to their infinite power, but 
then they cannot grasp the whole analytical truth, and will suffer 
similar limitation as the more terrestrial machines.
Here truth has nothing to do with any form of perception. We are in 
Platonia, by hypothesis. We keep our eyes closed, if you want.
Note also that without simple definition we would not progress, and 
would not been able to find our errors, or our limitations.

Thanks, Bruno, for the above and also your more lengthy response, and 
also to Jef for your response below.  After I posted the question below 
about Bruno's a) and b) I realised that I had set up a false dichotomy, 
and I was bracing for the appeal to Godel which Bruno and in a way also 
Jef responsed with.  I've been trying to figure out how best to pose 
what I was actually trying to get at and I've been busy, but I wanted 
say thanks for the response.  For now, I think that there's a problem 
with defining what a machine is.  As Bruno said, now we really don't 
know what a machine is.  So in the absense of a precise definition, 
perhaps we end up running away from ill-defined words like machine, 
reason, soul, faith, etc., for who knows what personal reasons. 
 I recognize that part of the problem is a difference in philosophy, 
the prime example being the Platonic vs. Aristotelian.  I guess this 
underscores the importance of Jeanne's original question about the 
place for philosophy in subjects like Artificial Intelligence.  Perhaps 
this is obvious to most of us here, but it is an interesting question.  
In fact, the very question Why philosophize? is actually 
philosophizing.  We humans just can't get away from it.  It's what we 
do naturally.  And perhaps this is part of what I'm trying to get at.  
A machine has to be interviewed by a human in order to philosophize.  
We humans are somehow the source of something from nothing in a way 
that a machine is not (Jef's something special about the human 
experience).  This is part of the definition of a machine, as I see it.


Back to thinking.

say we are machines in a totally closed rationalistic/naturalistic
world?  Brent and Jef's paragraphs sound mystical to me, as mystical 

as

any other first truth assumption.


I intentionally adopted a mystical tone in response to Tom's assertion
about modern philosophy being the death of humanness since I was
trying to relate to someone who appeared to be saying that there's
something essentially special about the human experience.

So I agreed, trying to show that from the subjective point of view,
the human experience certainly is extraordinary, but that it's all a
part of an objectively knowable, but never fully known, world.

My viewpoint is mystical to the extent that Albert Einstein and
Buckminster Fuller were mystical, acknowledging the mystery of our
experience while remaining fully grounded in an empirical but never
fully knowable reality.

To go to the heart of Tom's assertion about complete self knowledge,
in order for a system to fully know something, it must contain a
complete model of that something within itself, therefore the system
that knows must always be more complex than that which it knows.

It seems to me that much endless discussion and debate about the
nature of the Self, Free Will and Morality hinges on a lack of
understanding of the relationship between the subjective and objective
viewpoint, and that each tends to expand in ever-increasing spheres of
context.

Expanding the sphere of subjective understanding across an increasing
scope of subjective agents and their interactions provides
ever-increasing but never complete understanding of shared values that
work.  Expanding the sphere of objective understanding provides
increasing scope of instrumental knowledge of practices that work.
Combining the two by applying increasingly objective instrumental
knowledge toward the promotion of increasingly shared subjective
values is the very essence of moral decision-making.

Paradox is always a case of insufficient context.

I had a smart response here, and I just realised I had misinterpreted
the word copy here, so I just deleted it. Copy in English also
means to send something (envoyer) (I copied him in on the
conversation), as well as to reproduce something.

   Does it not seem incoherent to use terms that imply some form of 
*process* when considering notions that are implicitly changeless and 
static? This has perpetually bothered me in the discussions of the 
neoplatonians...
   BTW, copying is the identity morphism for computations (and 
informorphisms in general) in Pratt's discussion of Chu spaces...

Yes you are quite right (under COMP, and under the more regular meaning
of copy). However, I don't think this is how a Geiger counter works...

   It does seem that Bruno is considering the ticks, etc. of the Geiger 
Counter as included in the over all 1st person aspect of the bit string, 
this would include all aspects of the experience of the Geiger Counter...

This is the idea of getting the quantum indeterminacy as a particular
case of the comp first person indeterminacy. I think it is the idea of
Everett and everything-like theories.

but rather trivial from a
real, physical machine.

Accepting not only weak-materialism (existence of primitive matter) and
the quantum theory that is accepting the existence of primitive matter
and that it obeys to the quantum. But this is the kind of things we are
trying to explain (from simpler things, like numbers and/or comp etc.).



This is one point where I depart from your metaphysics. Traditional
aristotelianism asserts existence of matter, and that psyche emerges
from that. You assert the existence of numbers, and of psyche, and
show how matter arises from that.

I think both are needed. The psyche supervenes on matter, and the
properties of matter depend on the psyche. All of which exists because
numbers exist. There is a name for such a concept - strange loop. I
thought this name was due to Stewart and Cohen, but it appears
Hofstadter got there first in GEB.

**
[SPK]

   Are you considering a Categorical difference of classes here, in the 
sense that the classof matter structures/processes is different (in kind not 
degree) from the class of psychies? Have you considered Vaughan Pratt's idea 
for a relationship between them?

**

The reason I have come to this position is that try as I might, I
cannot remove the Anthropic Principle as an axiom. I would dearly love
someone to show that it is a consequence of other assumptions, or can
be derived from such by means of a simple, obvious assumption. But
most people I talk to don't even see the problem (perhaps because
they're still grounded in Aristotelian ways...)

**
[SPK]

   I concurr with this observation; it is as if most people do not see the 
deep conundrum that exist within the Aristotelian hylemorphism 
(http://radicalacademy.com/jdcosmology2.htm) in its assumption of a primal 
substance which, if I understand correctly, is seperated into its plethora 
of forms by many processes. It is the origin of the latter that I argue 
should be considered as fundamental, as a primitive class Becoming (ala 
Bergson), and substance is then shown to be the class of all forms that can 
emerge (think morphisms) from Becoming.
   Pratt's idea seems to add a dual to this morphism that would include 
such notions as computations; we then have a nice duality that avoid's 
Descartes' fallasy of trying to build dualism from substantivalism, ala res 
extensa and res cognitas.

I can do it on my computer, for example,
showing it to be capable of more than a Turing machine.

Le 06-févr.-06, à 22:32, [EMAIL PROTECTED] a écrit :





So Bruno says that:
a) I am a machine.
b) ...no man can grasp all aspect of man



To be sure, and clear, note that I have never said I am a machine, 
nor man is a machine.
All what I say is that:  IF I am a machine THEN  physics emerges from 
machine's psychology or theology. Both ontologically and 
epistemologically.


Now, I have made some progress, and strictly speaking, I can replace 
the comp hyp by the much more general lobian hyp. This entails that 
machines and a very large class of non-machine shares the same physical 
laws.


Of course my argument remains simpler to present with the comp hyp, and 
I still can refer to it for that reason.


b) become no machine, no angels, nor Gods can grasp all aspect of 
itself.
Even the Plato's and Plotin's big ONE can't, but it is not because it 
lacks something, in that case, it is more because it does not lack 
anything so that somehow it is far above the very idea of grasping.


See Boolos 1993 (precise ref in my Lille thesis) for an explicit 
description of an angel (by which I mean any loebian entity which is 
not turing emulable, but still follows the G/G* logic).







Tom says that to philosophize is one aspect of humanness that is more 
than a machine (i.e. simply following a set of instructions).



The idea of following a set of instructions is level dependent. I agree 
it is basically inhuman.
Now machine can observe themselves (in more than one sense) and this in 
general leads to unpredictable behavior.
With or without the quantum hyp. it can be said that man or nature 
follows simple set of instruction like following the (linear and 
computable) solutions of the Schroedinger Eq.





Jef and Brent say that we are machines who (that?) philosophize.


Well, if we are machines, we must admit we are philosophizing a liitle 
bit :)





Brent says that realizing we are machines is the beginning of (or 
another step in) the death of human hubris (arrogance).



I agree, but loebianity is almost the most general characterization of 
humilty and modesty.
For the modalist: humility = Dt - DBf, Modesty = B(Bp-p)-Bp. I will 
come back on this, when I will come back on the arithmetical 
interpretation of Plotinus' hypostases.





I thought that Bruno maintains that humility is on the side of 
realizing that we cannot totally understand ourselves.



No loebian entity can fully understand it-selves, and that gives to 
them many (really many) alternative exploration paths, which can 
recombine or not.






Pascal, Reason can begin again when we recognize what we cannot know.



Yes and no. Some have used that formula with the meaning that you can 
reason, but only starting from such or such sacred book on 
revelations. In particular I am not sure in which sense pascal did use 
it.






Could we try to make sense of this, given that we believe in sense?



I hope this help a little bit. I hope I can make it clearer, perhaps by 
finding a way to explain Godel's theorem and incompleteness phenomena, 
and how they are related to G and G*, and the discoveries of mystical 
machines (which are just machines which look deep inside themselves, 
in the Godel-Lob sense of self-reference).

Hi,

we (as observer) perceive at any given time a finite amount of information... 
so what you could know (still as an observer of a system) is finite, hence 
digitalisable at the level of information that you could know about the 
object, so I don't see why a radioactive source and the click pattern on a

I intentionally adopted a mystical tone in response to Tom's assertion
about modern philosophy being the death of humanness since I was
trying to relate to someone who appeared to be saying that there's
something essentially special about the human experience.

So I agreed, trying to show that from the subjective point of view,
the human experience certainly is extraordinary, but that it's all a
part of an objectively knowable, but never fully known, world.

My viewpoint is mystical to the extent that Albert Einstein and
Buckminster Fuller were mystical, acknowledging the mystery of our
experience while remaining fully grounded in an empirical but never
fully knowable reality.

To go to the heart of Tom's assertion about complete self knowledge,
in order for a system to fully know something, it must contain a
complete model of that something within itself, therefore the system
that knows must always be more complex than that which it knows.

It seems to me that much endless discussion and debate about the
nature of the Self, Free Will and Morality hinges on a lack of
understanding of the relationship between the subjective and objective
viewpoint, and that each tends to expand in ever-increasing spheres of
context.

Expanding the sphere of subjective understanding across an increasing
scope of subjective agents and their interactions provides
ever-increasing but never complete understanding of shared values that
work.  Expanding the sphere of objective understanding provides
increasing scope of instrumental knowledge of practices that work. 
Combining the two by applying increasingly objective instrumental
knowledge toward the promotion of increasingly shared subjective
values is the very essence of moral decision-making.

Paradox is always a case of insufficient context.
