Re: Souls - Your opinion.
The way I see it is that mind has no independnt existence. It's pure information and requires a substrate to be. It's an example of nonbeing in being (one of those categories of existence that the East has but the West never recognized.) The substrate can be any densely connected network. Either the body or the spirit fits the bill. Since the body and spirit share the same mind, that's the interface.
I've been in the spirit pool and our language doesn't work there, but the closest I can come to describing it is that the spirit doesn't perceive; it simply knows. So it doesn't perceive self; it knows self. Since consciousness is a form of perception, the spirit isn't precisely conscious. What it is, though, is something orders above consciousness. It's not "located", in other words, it's not bounded by time or space. It's both everywhere in the universe or it's nowhere. All spirit coexists - which is why I talk about the "spirit pool". It's as if you're in a pool but instead of water, your in spirit, except that you're the spirit.
In a way, our universe has a spirit but there is nota multiplicity of spirits.But there are a multiplicity of spirits - God is separate from the spirit of our universe, but it's not a spatial separation. All spirits are in the same "place" - except there is no "place" outside the framework of our universe, unless it's in the famework of another universe. But space and time only exists within the gramework of a universe. Outside of the universe, those things don't exist anywhere.
I'm, per force, an animist. All things have spirit. Spirit is the template on which all material and energy things have form. In the spirit pool spirit is like the sound of an orchestra. If you saw the sound (say, on an oscilloscope) it would be one complex waveform. Amazingly, the human ear can pick out each component of such a complex waveform. It's not that the sound of the oboe exists in the complex wave, but the information of the oboe is preserved and can be recognized by the ear/brain. In the same way, spirit isn't a conglomerate of a multitude of spirits - it's one thing, but the information of each entity is preserved in the whole.
And that's only an allagorical description, which is the best I can do, but it's not nearly good enough.
