photographs and musical notes as soul-shards, avenues to interiority

 

what has interiority?

what is it like to be a tomato? J

where do people go when they die? mostly gone, but soul-shards left around, distributed in people�s brains

 

Chopin etudes, Schirmer editions, pieces of text, American critic, James Hunicker(sp???)

favourite: Opus 25, no 11, sometimes called �Winter wind�

�small-souled men, no matter how agile their fingers, should not attempt it�

 

magnanimous being stepping on a minianimous being (with the sole of a boot) J

 

continuum of consciousness � humans senile/retarded dogs viruses

 

so what would retard the growth of an adult soul???

 

Molecular gods: how molecules determine our behaviour

�who pushes whom around, inside the cranium� � Roger Sperry

 

brain structures

list of physical ones

and also:

the concept �dog�

the associative link �cow� <-> �milk�

an object file (Treisman)

frames (Minsky)

scripts (Schank)

memory organisation packets (Schank)

LTM

STM

analogical bridges (FARG)

mental spaces (Fauconnier)

memes (Dawkins)

ego, superego, id (Freud)

 

look up Tresiman, Schank, Fauconnier

Schank, 1982, Dynamic memory

 

perfectly valid to talk about concepts (even though we don�t know how to define them as physical entities in the brain), just as we did good research into genetics before learning about the substrate

 

the goal is to relate the software structures to the hardware structures

 

can a thought push an electron around?

 

why didn�t the domino fall?

because the previous domino didn�t fall

OR because the domino rally is a program for calculating whether there are a prime number of dominos in the input zone, and there were a prime number of dominos

different level of explanation in terms of the primality of an integer

 

dialogue � the �careenium�

small yellow magnetic (SYM) balls

whether small things make the big things jiggle (at high speed) or the big static-seeming things obstruct the small things and make them pinball off (at low speed)

 

reductionism (upward causality) + predictionism (upstream causality) = mechanism

holism (downward causality) + goalism (downstream causality) = soulism

you can just look at the universe at the atomic level, and not see it in terms of functions � but without a model you won�t survive long

 

�teleological, entelechistic shorthand is a sine qua non for survival in a complex world with real-time pressures

this shorthand is in fact the native language of the entities that use it. other languages seem incomprehensible�

 

Waves in the Berkeley series (frank ???) � two soup cans suspended from the ceiling, placed inside a slinky

natural oscillator � energy is transferred from one to the other at a regular periodic

normal modes

difficult to solve the differential equations for positions x1 and x2 as a fucntion of time, but easy to solve for x1 + x2 and x1 � x2

superposition of normal modes???

 

sat in front of a TV taking pictures of the TV for hours in 1977

feedback

 

I�m the most permanent thing in my life � that�s why my self-representation is so complex � but I�m not actually the most obvious thing in my life, which is why it takes a while

 

box of envelopes

all together, feels like a marble � but no marble � tiny spot of glue in the same place that mounts up

if you were only to trust your senses�, if you�re prevented from seeing the lower level (i.e. look between the envelopes)

you can�t look into the brains, so all you�re able to do is see and feel the �I�, which feels more real than anything else

unwilling victims of a hoax that there is some real thing called �I� in the brain � at a certain level of description, the �I� vanishes

 

�cogito, ergo ego� J ???

 

does the nature of the neural substrate affect the way we represent ourselves at all, or could it be any flexible, distributed, emergent, dynamic substrate that instantiates the function of our self-representation???

 

interesting, elitist off-topic issue that the Hunicker quote was really getting at when it talks about small-souledness, i.e. what determines the size of soul of an adult, normal human being???

he avoided the question � didn�t want to be pinned down on it (despite the way he was talking about it earlier), or to try and measure a �soul-quotient� � although he argued that society does make a sort of evaluation of soul size when imprisoning or firing people

I was more interested in his personal criteria � he basically said it was a matter of taste

 

tell Leon: there is more than one way to sense �I� � he�s arguing that it�s different from the �marble�, because you can sense that in more than one way

 

me vs I (James) � looking out at the world vs looking into yourself

 

soul-shards: it�s not just that memories of his late wife are in his brain, but that actually some part of her consciousness

e.g. whenever he thinks about things that meant a great deal to her, it makes him cry

very dilutedly (not deludely)

 

he talks about AIBOs scoring goals as being 0.000000000001 conscious

but how would you quantify that???

 

is a heat-seeking missile (briefly) happy when it reaches its target? probably not, because its representational system is so impoverished

cf is a virus alive?
