I made her a hand muff by sowing rice into a quilt. You put in in the microwave for a few seconds and the heat goes into the rice. On a cold day you stick your hands in it for warmth. Wish I could say it did more than distract her a little.

Actually I think not. Analyzing the pattern of behaviour of a physical system, even if you end up completely understanding it will not yield a prediction that they will become conscious. It's a non sequitor. The complexity of a system, nor the type of system, implies that it will be conscious.
It depends how deeply the patterns of behaviour are analysed, doesn't it?
All that complexity does is increase the dimension of the state space that the initial and final vectors have. It does nothing to change the fact that the final vector, is just another vector in the same state space and none of the available operators, position, momentum, angular momentum etc, and the properties or charges of the system, color, charm etc nor the flavor of the system speak at all of the system becoming aware.
Look, here is how you can prove me wrong. Look through the descriptions of quantum mechanics for an operator that will have as input the state of the system (a vector in Hilbert space) and have as output the probability that the system will be conscious and/or be conscious in a specific way. If you find one let me know and I will yield the point.
But if you don't find it, remember that adding complexity just increases the dimension of the state space. It does not add the missing operators, nor does it define the phenomenological spectrum, the set of possible qualia if you like, where "possible" here means what kind of experiencing can be produced given an arbitrary state of matter.
At a very basic level, nervous system activity is a kind of behaviour. Dare I say it, it could be a quantum thing LOLYea I agree that the nervous system activity is a kind of "behaviour" if by that you mean it does something. And it is of course described best by quantum mechanics. But the interesting thing is that in addition to basically "moving" which is what physical systems do given a generous definition of the term, and that is all they do according to the existing physics, still they seem to cause awareness.
...If I'm to throw off the shackles of the verifiable - as if writing a sci fi story or creating a myth - then I might speak about the possibility of pantheism or panentheism.I sort of use Occam's razor. I think that we know that even small changes in the chemistry of the synapses of our brain can render us unconscious. On the other hand much of the complexity of our brain is to render our senses and provide motor neuron activity. But some aspect of it also seems to create conscious awareness. There is a need to posit that that happens just based on our experience but I just don't see a reason to believe rocks are conscious. Nor thermostats. I think though, that the production of consciousness probably does not require connectivity to senses nor motor activity. At least logically it does not. We will see when a clear definition of what causes it is obtained.
.... To relate back to the river analogy, long term memory would be the river channel - the groove caused by long term erosion - while short term memory would be more akin to the slight, constant eroding of the outer surfaces of the river's channel.Never ceases to amaze me that river analogy. We use the word "current" for the water passing by in a river. Upstream is the past. Downstream is the future. Being and Time. Seems like consciousness requires time. Not sure being in general does. Look at the Pythagorean theorum. Imagine that all contingent being ceased, or even never was. Wouldn't the theorm still *be* true?
I think the link might be wrong? Anyway, I have read that story Feynman tells of his father and the leaves. But I do think Feynman never actualized metaphysical awareness. I do not think he ever experienced ontology in the non-standard ways available to us. And consequently, absent those experiences, he couldn't really do metapysics very well.
One of the finest of all minds had the same issue: https://www.youtube.com/watch?v=lFIYKmos3-s
As Feynman says, names matter when you are trying to communicate, but the names in themselves don't constitute knowledge.
But he was a great physicist and I love that about him. He had an honest mind. I was amazed that, in the end it was Sally Ride that figured out the challenger disaster, or rather, no figuring out was required, the cognizant engineer fully expected the explosion and knew what was going to cause it prior to launch, but he trusted her to get the story out and to avoid damage to her carreer the message was passed to Feynman only after her death. For years, the story was about how Feynman was passed the message via motorcycle parts.
That disaster was negligent homicide at best, and frankly it was worse. Feynman was right in his annex. NASA lies.
I also remember the second loss of a shuttle. I was lying in bed and watched it practically live. Went nuts when NASA said the foam hitting the wing could not have been the problem. Yes, they said it because I saw them on TV sat it. Latter in life I was showed a memo recommending that a test be done by firing a piece of ice at a wing section. Once you see that video, you just shut up. Case closed. In both cases it was the Air Force generals who kind of pricked the bubble of NASA's attempts to bury the story. They were no friends of the shuttle because they knew how much of the program cost was fraudulently burried in military budgets. Money corrupts, that is for nearly sure.
That wing video was the second disasters' analogy to Feynman's O-Ring material in the cold beaker.
I mean it made me very angry. Ok, you have a piece of ice hit the wing. So in descent, one by one your thermisters in the wheel well RIGHT BEHIND WHERE THE WING WAS HIT, start to fail... and then the spacecraft yaws and disintegrates and you don't think there is some possibility that it was the ice? Well a first year engineering student might think otherwise. And as you can see in the first disasters annex by Feynman, the o-rings were not the only problem NASA was burying. I went to NASA once at Johnston and swore I would never return. But I have to admit once you get inside the ring of astronaut groupies to the real operations teams they were great. I think of NASA as a donut with a core of solid ops people surrounded by a disastrous managment team.
As a team they failed twice. In both cases I think Feynman was right. The problem was the way the managers biased their judgements.
It's easy to think of "something flowing"...but that is never going to be "awareness". It is simple equivocation. "Something flowing" may cause "awareness" but it is not as a result of that the awareness of which we speak. You can however, change the properties of "something flowing" and in the material case then have flows that are conscious.Justintruth wrote:Be careful with the word "flow" as someone will think you mean "flow of something"....Actually, in these thought experiments I envisage a flow of atoms and/or quanta.

For instance, if I picture a green equilateral triangle on a white backing that completes the "field of mental vision" then a neuroscientist could readily identify the neuronal patterning resulting in that visualisation. If I ask you to visualise that triangle, one might expect significant similarities between the neuron patterning.
What has happened to transfer that pattern from here to there? How do we trace "A" - the pattern in my neurons - with "B", that similar pattern in yours? The figure in my mind is transferred into English words, a pattern of finger movements, electric flow along the tracks of a keyboard, a digital pattern of electricity that travels along the cable to the PC, the black and white squiggles on a screen that we somehow understand, etc.

These are excellent questions. Maybe you should get into a lab and try to answer them? Some of the material is known already.
