OK. (Lots of open questions there, but I'll ignore them for the sake of argument.)
Quote:Then the question becomes, how did matter give rise to consciousness?
The question that I would ask at that point is what does the word 'consciousness' mean?
That's the rock that the philosophy of mind ship always seems to strike. When David Chalmers proclaims what he insists is the "hard problem", it only seems hard to him because he's conceptualizing 'consciousness' in such a way that it seems to him to be incompatible with physicalism.
My first reply to Chalmers would be that we won't know whether or not the problem is really "hard" (in his metaphysical sense) until we have a lot better idea of what it is that we are attempting to explain and make consistent with the rest of our worldview.
Quote:What are the properties inherent within matter that allow for a being to compose Beethoven's symphonies, discover a new law of Physics, create life?
Well, my own inclination is to try to conceptualize those kind of things functionally. Consciousness and intelligence (as I conceive of them) aren't ontological substances, they are activities performed by (material presumably) substances. That's seemingly consistent with all the brain physiology stuff, where awareness and intelligence aren't necessarily present whenever brain substance is present, but are only present when the brain substance is behaving as it should.
And my idea of how to study it would be to trace it back to simpler antecedents. The human brain is incredibly complex so studying it is going to be very difficult. So we might make more progress by studying simpler brains in simpler organisms.
One place where that's happening as we speak is with the tiny nematode worm
Caenorhabditis elegans. The most common variety of this little animal only has 959 cells in its entire body! It was the first multicellular organism to have its entire genome sequenced. So it's become the go-to organism for basic studies of how the genome directs anatomical development.
What's more, its entire nervous system consists of 302 neurons! (The opposite end of the spectrum from human beings, I guess.) These have been extensively mapped and their thousands of synapses identified. Despite the simplicity of this little nervous system, these worms display a whole array of behaviors and even seem able to remember and learn to a very limited degree. It even has a little brain, in the form of a nerve ring around its pharynx. (Many animals such as worms, insects and octopuses have brains that encircle their pharynx and in effect eat through their brains.) As we speak, lots of work is being done on what this tiny little 302 cell C. elegans nervous system is doing between sensory stimulation and behavior.

Quote:If there is some extra property in matter that we have not ascertained, I ask, what is it?
I don't conceive of it in terms of 'properties'. Perhaps the only property of matter that's necessary is causation. So I tend to reduce consciousness to causation. Kick a small rock and it moves, stimulus and response. I suspect that all the rest is elaboration on that theme. (I can already sense CC seething at that idea.) The question (as I conceive of it) is how causation compounds itself into more complex behaviors. Ultimately ending up in organisms with nervous systems of billions of cells that are able to use language to communicate, form ideas of things like abstractions, and are able to intuit (some of) their own inner states. I don't think that we are anywhere near close to explaining that. We can't even really describe it at this point.
So I can't really prove that it's built up out of simpler causal components. It's more of a heuristic hypothesis, my working assumption at this point.
