Well, of course, I was playing a language game. However, it is still interesting that it seems no matter how hard we try, we describe the brain as a tool for some other entity. Even your use of the word "thing" falls into this trap, because then you have to explain just what this thing is, and where it comes from. Superficially, you can say, well, it comes from the brain, but then you get into a physical (not necessarily logical) circularity about the relationship between the essence of the self, or consciousness, and the brain, and the cognition that results from it. Such an identity theory is laced with problems in my view. Thus, it seems quite natural to fall back on natural intuitions that suggest a separate "soul," or whatever you want to call it, and ask whether there might be an explanation that is consistent with some sort of co-existance.

One thing that credible reincarnation reports do is cast serious doubt on the standard materialist view of consciousness, which partly expains why philosophers and scientists are so resistant to these reports. Nonetheless, they cry out for explanation, which, as I previously noted, is difficult to muster in a way that dismisses the phenomena and preserves the traditional materialist view. Perhaps, the message of reincarnation is that our materialist world view needs to be reexamined. (I assume you realize that by "materialist" I mean the traditional use of this term that does not encompass quantum considerations)

Well, if I understand you, I would say that the traditional philosphical arguments that address the mind-body problem by debunking dualism are misplaced because of QM. Certainly, the idea of reincarnation does not depend upon a traditional, Cartesian dualist position. In fact, it works best when the notion of immaterial substance is abandoned altogether, and we consider the "soul" as an aspect of physical reality in the broad, modern sense.

Well,first I think you have the issue backwards in the following sense. Once the reincarnation experience is established as a credible psychological phenomenon, then the scientific question is how do you explain it? The phenomena itself suggests an independence of the brain and the soul. If this is wrong, then there must be in principle an explanation for it. Moreover, the explanation must go beyond claims of fraud, or even neuroscience. The explanation must somehow encompass the fact that the living person identifies with a deceased person, and is able to provide historical, and personal facts about the deceased person that he or she could not under normal circumstances have known. I do not see how in principle this can be done without some sort of paranormal component.
Now, your point turns the tables by asking how QM, even if explaining consciousness, could explain reincarnation. That may in fact be very difficult, but the result of this objection, if valid, is that reincarnation is left unexplained, not, of course, refuted. The lack of a viable scientific explanation does not dismiss an otherwise established phenomena as being invalid. If QM cannot explain it, then its back to the scientific drawing board. We cannot simply conclude that reincarnation experiences must be a hoax. (This is a very important point often missed)

Probably, but not necessarily. Correspondence does not imply ontological or causal dependence.

Quantum fields do not require "pebbles." Quantum fluctuations exist in space-time independent of any material cause, and matter is generated and organized from such fields as part of the natural order. What other micro-tricks such fields are capable of we do not know.
