Right but I thought your position is that matter is not primitive, so
that all of physics that pertains to matter is an epiphenomenon of the
underlying computation. I thought your view is that the brain itself
can be virtualized so that "I" can be run as purely digital
application in any computing machine with enough power.

How do you know that it's not the computation which is only an
appearance emerging from the physical universe, which inherently
includes the potential for consciousness? If you ask computation which
is primitive, it can only tell you that it is because it has no
capacity to make sense of anything else. If you ask only myself what
is primitive, I say awareness. To me, the primitive is the symmetry of
the two and the function of that symmetry in influencing perspective -
which is to me, sense-making.

Because awareness wouldn't be necessary for machine computation.
Computers require no monitor or keyboard to compute. Also, awareness
requires no familiarity with computation. We feel and see without
having to understand arithmetic, even indirectly. I don't need to know
that blue comes between green and violet on the spectrum or that is is
a primary color or it's the opposite of another color, I can see it
directly as a self-explanatory phenomenon.

By sharing the same history of being the same single cell and staying
in continuous contact I suppose. It's just how awareness works. It's
not like objects in space, it's subjects through time. They are
semantically entangled as a multi-leveled shared experience in the now
- a now which is the tip of the iceberg of all experience. It's like

Actually, this article says recent neuroscience suggests the brain is
not a computer:
"The Cornell researchers found that the brain continuously shifts
between states rather than having internal "variables" that contain
discrete "values" that are updated as the result of calculation
processes. According to researcher Michael Spivey, "In thinking of
cognition as working as a biological organism does... you do not have
to be in one state or another like a computer, but can have values in
between -- you can be partially in one state and another, and then
eventually gravitate to a unique interpretation, as in finally
recognizing a spoken word." The brain is not composed of modules that
pass the results of calculations back and forth; there are no
"results," just continual modulation. "

It's got ventricles that it's constantly filling with fluid that
circulates around CNS. It's got billions of cellular neurotransmitter

Is there ever an advanced technology that isn't a machine?
"The seductiveness of the analogy between human neural activity and
digital symbol manipulators has proved irresistible. It has been
characteristic of Western thought throughout the modern period,
beginning with Lamettrie's L'Homme Machine in 1750. Seeing humanity in
the image of which ever machine most dominates contemporary life is
what might be called mechanemorphism. With Lamettrie it was the clock.
The combustion engine followed. Freud thought electromagnets were a
good metaphor for the brain. Today, this tendency finds its most
extreme expression with the computer, especially amongst the
proponents of 'strong' artificial intelligence. Mechanemorphism has
conditioned not only our overall attitude to computers but also the
very terminology that has arisen around them."
"Over at BLDGBLOG, Geoffrey makes an astute observation about how the
latest consumer technologies have a way of becoming metaphors for the
mind. Before the brain was a binary code running on three pounds of
cellular microchips, it was an impressive calculator, or a camera, or
a blank slate. In other words, we're constantly superimposing the
gadgets of the day onto the cortex. Geoffrey notes that a recent
article featured on the BBC on fMRI scans of taxicab drivers ("Taxi
drivers have brain sat-nav") is very similar to an earlier study,
except that the most recent article used satellite navigation as a
metaphor for the spatial memories storied in the hippocampus:"

How can we compare the brain with something else when the only
consciousness we have ever experienced is through our own brain? If we
compare the brain with anything else - like a loom, or a player piano,
or block of cheese, we know that those things don't have human
consciousness, so why would we be interested in treating them as part
of the same category? Consciousness is the only thing that is
important about the brain.

Because comp would just assign a memory pointer that has no aesthetic
qualities at all, let alone a specific category of qualities and
associated semantic tonalities and textures. Blueness would be a
functionally redundant addition on top of the actual quantitative

Just the opposite. It slows it down. If you need a frequency-
wavelength quantity to begin with to assign blueness to, you already
have the precise criteria that is useful for decision. It would be no
faster to add on a flavor or color, and even if it were, where do you
get these flavors and colors from?

It could. If being me is more like seeing blue than it is like a

I would agree with you in any other area other than consciousness.
Subjectivity can only be 'proved' by authoritative argument. The fact
that we are able to locate our own authority is itself a refutation of
comp. A machine cannot do that.

Because the preferences come out of the sense and motive of the body
it is being incarnated into. We are not the music, we are the musician
and the audience. It's not necessarily transferable, and if we
discovered how to make it so, there might not be any point in playing
the human game any more in the first place.

I don't think computers or machines have any of those things except to
us. I can connect a fire extinguisher to a computer and it's still not
going to have the sense to activate it if I set the computer on fire.
It doesn't matter if it's Watson or Deep Blue, it's going to sit there
and burn down to a heap of molten slag, flashing 'Fire extinguisher
connected and ready' until the very end. If an entity can't muster an
opinion about it's own existence, if it has to be told how to act as
if it cared, then how can we really consider its intelligence
mimicking algorithms 'opinions' or points of view?

I agree, we can learn a lot a lot from them and we should listen to
them. I think we can learn even more if we adjust our expectations so
that we understand that machines tell us about the exterior of the
universe and the opposite of the interior.

See that's the crazy part though. Why do numbers have dreams? Do their

Why do they speed up computation and decision? Isn't that like saying
it's faster to run a program in a high level programming language than
compile it into machine language? Even if they did, why generate these
elaborate aesthetics, and most of all how? Are numbers omnipotent? If
they need to tell the difference between one thing and another can
they just invent whole new palettes of primary colors and novel
dimensions of sensation? To me it's like saying, 'hmm, these filing
cabinets are getting pretty full, maybe I'll reinvent space in a way
that it appears to be concretely charged with emotion, yet clearly
communicates an intention towards non-subjectivity.'

If you define machine that broadly though, you aren't really saying
anything about anything. If we can't know what they are capable of,
then we can't be sure that we should call them machines. It's
tautological to say we know that machines can be like us because if we
assume we are machines then machines would be doing what we do. If we
assume that we are weapons then we can say that we cannot know what
weapons are capable of. Maybe computation is just means to an end of
weaponry? It's somewhat of a sophist position, but really no more than
comp to me. Hence the term 'rocket science'. Where did computers and
networks come from? The military.

I do doubt their imagination though. My computer doesn't have an
imagination. The whole internet has no imagination. Just users of
brains. I'm willing to accept that computing is in it's infancy so I
would set the bar pretty low, but I have seen nothing yet which
strikes me as having an authentic voice. Computer music is the music
of plastic. It can be pretty, but it's not an expression of creative
teleology, it's just abstract noodling. It is the magnificence of the
human imagination, for better or worse, that is able to derive such
knowledge, insight, and power out of what I consider to be the
immaculate sterility of machine intelligence.

But what if the quality of Löbian self reference is not authentic?

A cartoon is different in it's behavioral capacities from an
interactive program, but that just strikes me as a degree of
sophistication and not an indicator that a program is any more likely
to develop its own sense of self. I can make a cartoon where the
characters act like they are talking to the audience. All I have to do
is select my audience members carefully and my cartoon could address
audience members by name.

What about a ventriloquism dummy or actor on a movie screen? Those are
real things that seem to us like they might have a self, but they do
not. Their selfhood is an extension of a human agent, just as a
machine is an extension of a group of programmers or engineers.

I think it's just the opposite. Physical reality is a concrete
singularity, it is the divisions of that singularity which are
diffracted as object surfaces in 'space' and subject depths through
'time'. What you are talking about is true too, but it's inside out.
You're trying to model the outside of the universe when it can't have
an outside by definition. Matter is the stuff. That's where the action
is. Inside of matter. Like our brain. As a primitive, it's not matter,
because it's the divisions that make it matter. The divisions create

Ok I am getting more the difference between universal computations and
computations, but I think that the universality is sort of like sense
spread out to it's thinnest possible layer so that in order to apply
to everything, it must mean nothing but what it literally refers to.
In this way it's not truly universal because it's only true in this
one narrowly defined generic sense. Arithmetic is sense with all of
the significance boiled off, leaving you with the essence of a-
signifying semiotics. In this way, arithmetic truths trace a boundary
around where significance is supposed to be, revealing it by making
it's absence clear. You can't change the structure of numbers because
only the formalism of their intent is real. I can make one drop of
water by adding four smaller drops together. That contradicts
universal numbers, but it doesn't make the truths it contradicts any
less true. What is real is the human sense and motive behind the
numbers, not the numbers themselves.

Definitely. That's why computationalism is really kind of a minor
point from an engineering perspective. We don't want real AGI so
knowing that the way we are trying to get it is wrong should free us

Absolutely. All I want for Christmas is a flying solar yurt made of

Wouldn't they be enumerated rather than incarnated? I guess I agree
but I would say that there is a vast class of sense which we can make
which is not arithmetic and we do not share with numbers. If
arithmetic is that thin layer of sense stretched out to embrace as
much machine (external) truths as possible, then the psyche is a
towering pillar of sense reaching upward and inward to non-machine

Brain-conjoined twins can refer to themselves as I, but identical
twins don't. That suggests that neurological connection is the basis,

What is money though? Computation enacted socially. All goods and

Locally in two opposite senses. Local to the body and local to the
subject. My experiences are local to me in my memory, but not to my
body. My cells and organs are local to my body bit not my psyche
