Hmmm... slightly confizzled as to the question (well, maybe not confizzled, so much as I've had a long day and didn't feel like trying to comprehend what's really going on... Sorry... ^^

but, for now, here's a quick clear-up:
Go to the manga viewer and read chapter 44: The Nameless Grave. That's Ed's entire discussion and thesis regarding mind, soul, and spirit.
The basic idea is that the
spirit serves as an invisible connector between mind (or, arguably, body) and soul. (Rather than mind, body, and soul)
Ed's theory is that while Al's soul is in the armor, the spirit serves as a connector between the world and the gate. Ed then talks about his and Al's spirits "crossing," and so that may be why Ed has to sleep a lot, eat a lot, etc. - he has to take care of Al's body, too, to keep it from decaying like Barry's - so, here's my theory:
When Barry's soul was transferred to the armor, there was no one to care for the body via the spirit like Ed does for Al's body... But, Barry is still able to "sense" his body b/c of the connection that the soul and the body both have, despite the body housing a different soul... So that's why Barry could recognize his body - but his body wasn't able to respond to him b/c the mind was "overshadowed" by the soul of the rat (or whatever that thing was...)... So, Barry can sense his body, but he nor any one else can directly "communicate" with it b/c the body has the soul and mind of a rat, and the spirit connection between Barry's soul and body was weakened. Make sense?
As far as Al's body goes, his mind is there, still functioning and storing memories like Ed said it was... but, Al is still able to think for himself... Think of it this way: The "essence" of Al, if you will, is stored inside the soul, and the mind stores "raw data" - kind of like a computer drive. Al's spirit connects the two (mind and soul), thereby allowing him to both look up and store information in his mind even though it is seperate from him... More of a philosophical thing than a scientific, physical one, but you know... Does that make any sense? I can explain it more, if you'd like...
But I don't think that Al's body would be able to host a different soul and still remain "Al" - remember the computer drive allusion? Al's body is acting as if it is a computer - using information it already has, but devoid of Al's personality - the mind is almost like a seperate entity, and only by the soul being housed in the body, and connected by the spirit, can the two work harmoniously together to create an "entire" Al. So, arguably, if you put another soul inside Al's body, Al's body would take on the mental characteristics of whatever soul the body was storing... It's also possible, like with any foreign soul housing anything, that it could be rejected - but there's no telling what makes something more likely to be rejected or not... I think, though, that Al's pretty safe in the armor b/c there's no "original" soul to try and make him leave... If another soul sought refuge in Al's body, it may have a harder time trying to stay, if Al (his soul) was strong-willed enough... But no, not quite entirely like a mind-less puppet - more robotic, in a way - just going through the motions, and reacting to things based on the information and memories that it has. It wouldn't really be "Al" though - it couldn't feel in necessarily the same way that Al does, kind-hearted and caring, without the soul...
Al's body said that to Ed b/c, like a computer, it recognized something foreign, and gave out an "error message" - actually, I think a computer is the best way to think about a soul-less body, don't you?
Hopefully this all made sense! If not, I can keep going over it! ^^
Quick rap-up:
Soul-less body = computer (has info, but no distinct personality)
The Soul = what makes a person unique, rather than an info-storing device
-The New FMA
Hmm, not exactly what I was talking about...
and note that I wasn't looking for an "explanation" of whatever that's already been mentioned and explained in manga =\ Of course I know whatever that was already explained by Ed in chapter 44, so I didn't need another explanation from that chapter, really (and I hate mange viewer...)
what I am looking for are more like view points and opinion. What Ed said is what he thinks. Maybe it's not reallllyyy exactly like that... Chapter 53 only confirmed his "mind connects the soul and body" theory, but what I want is a even more detailed explanation of soul and body (so yea, from what everybody here thinks, don't quote explanations from the manga anymore please since it's pointless.) Note that what I said up there are like, what I think, not really fully accordingly to what manga has explained. The computer analogy is interesting, but well... imo it doesn't sound "right" to me (I don't mean that you are wrong... just that the processor in my head doesn't really accept it. XD) My major question is asking how people think Al's body would function OUTSIDE the gate while remain CONNECTED to the soul INSIDE the gate... while what you said are mostly how Al's body would be like if it's DISCONNECTED from the soul... which isn't really what I am asking for.
Al's soul was able to function outside the gate, BECAUSE the soul is still connected to the body that is inside the gate. Would Al's body be able to function outside the gate as well if it's connected to the soul that is located inside the gate? <--- My real question. I think my starting post is too messy or something... maybe I should clean it up......
but then I am so damn lazy.QUOTE(ExhileVoid @ Jan 24 2007, 07:58 PM) [snapback]497200[/snapback]
There's a another thing I've been meaning ask about the body and soul too. In Chapter 33, Fuu-jisan said when he fought Al, he couldn't feel the flow of ki/chi inside Al's body that all living human being should possess. But when Lan Fan fought Envy, he asked him just how many people are inside of him. Ling and Lan Fan said they can sense the unusual ki/chi that the non-human based homunculi possess. How is it possible that they sense Envy's abnormal ki/chi since they were all souls but they couldnt sense Al's ki/chi? Does the soul have ki/chi?
Hmm, good point... the philosopher's stone is really essentially just a concentration of countless souls, as Envy has clarified for Ed... But then to what I know about ki/chi (I might be wrong), it's not really sensing the soul itself, but sensing the energy that flows inside one's flesh body.
I guess you could say that, Ling and Ranfun were able to sense the FLOW OF ENERGY inside Envy. In order to use his power, Envy has to convert the concentrated souls into a usable form of
energy inside him... and perhaps that
energy is actually what Ling and Ranfun were able to sense? Since there are many different souls in the stone, so therefore there are many different forms of
energy inside Envy, in which lead Ling and Ranfun thinking that there are many of them inside Envy...?
Argh, but then now it doesn't make sense in King Bradley's case, since Ling and Ranfun were only able to sense him as an "individual", not a bunch of people... maybe because he is human-based humunculus so he converts energy differently? >>;;
I don't think I recall Wrath ever got attacked by anyone... maybe that energy can only be sensed when the homunculi regenerate themselves? Or maybe Wrath is so l33t that he never actually needed to use the stone's power except for his eye... Argh, I don't know anymore XDDDDDDD
So Al doesn't have any ki/chi because he has no flesh? You need flesh to convert the energy and uhhhhh........ maybe that evergy conversion happens inside the gate @ gate!Al's body? XDDDDD *gets shot in the head for making all these even more confusing than before*
