Not sure what Shannon has to do with this, but never mind..

Yes. My brain.

Yes. My brain, processing particular information in a particular way.
I'm not sure about this business of calling it a 'causal property'. That seems to be confusing things. It's a process rather than a property. My brain /does/ something, which I describe as 'feeling a certain way'. This makes more sense than saying my brain /has/ something which 'is a certain feeling', because that leads you to think that the feeling is an independent thing, which is obviously untrue, because when my brain stops working, the feeling ceases to exist.

OK, so you're talking about the same thing as me: The processes performed by the brain that we call 'seeing green' or red, or feeling hungry, etc.

No, of course not. Do you think that it's possible to just have a song, with none of the chords, harmonies, rhythms and lyrics that are 'bound up' with it? Is there such a thing as the 'elemental "Bridge over Troubled Water"' that can be separated from the words and music? If you separate out the constituent parts of the 'redness' experience, it goes away. As in, doesn't exist anymore.
You seem to be dismantling the clock in an effort to find its tick. The tick is real, it definitely exists, so it must /be/ something, right? So why can't you find it when the clock is in bits?
Also, please could you avoid top-posting? It makes things difficult to follow. Thanks.
