On your last point - that recovery means that the person was not near death - we disagree. It seems from your post that you do not accept that death is a process and not a state. The majority of clinicians would also disagree. They are a precise bunch and would not use the term ‘death’ or ‘near death’ unless it had a real, clinical meaning.
There’s an irony here. This thread is partly about a big mistake made by clinicians who placed a live man in a morgue.
I have to be precise in what I mean about nearness to death. It is true that, as a practical matter, clinicians do have to determine some kind point of no return, a point at which the determine that the patient is beyond all help or in an irreversible physical condition, and crucially the heart. But clearly, this point is not passed by any NDEs, and though they are in danger of going beyond that point, they haven’t passed that boundary, since the point of irreversibility is…well…irreversible. The problem with the clinical definition of nearness to death is that the term is relative in terms of the resources available.
A condition that is easily resolvable in the Mayo Clinic may be much more grave in a small regional hospital. Likewise, all modern medical hospitals are able to easily respond to certain kinds of heart attacks with treatments unheard of a century ago. If your heart stops, then you’re dead, according to medicine back then, and that was because they had almost no means to revive or repair a heart. Or for a man in the desert with a broken leg, delirious with thirst and pain, death would be near, but only if help is not. A glass of water, a splint and a helping hand may be all he needs. So the clinical definition is only relative to the available capabilities to save someone in a precarious condition, and not the absolute condition of the brain, the seat of consciousness, and the brain is what makes you who you are.
The only thing I’m trying to say is that from the naturalist perspective, a “Near Death Experience” is a misnomer. I’m not even trying to discredit or debunk the supernaturalness of NDEs, but for me, NDEs are given an undeserved mystique by its apparent association with death. That association is also parlayed into evidence of an afterlife, but that’s not going to fly with an armchair naturalist who can afford a much more narrow definition of death than the urgent lifesaving but relative considerations of a clinician, and the much vaguer ideas of the general public.
I have a student who had a cardiac arrest at school. He was seconds away from death. His heart and breathing had stopped, he was completely unconscious. Are you seriously suggesting that he was no closer to death than I am as I sit here typing this?
No, I’m suggesting that he was no closer to death (that’s assuming he recovered) than a person almost being hit by a train. Although the student’s body was in a worse condition, the damage wasn’t sufficient to cause brain death. And he is closer to death than you or I am typing but only in the sense that he is in real danger of dying and not the sense that he experiences brain death. Precariousness does not equal closeness.
Brain death, as I stated is irreversible. Changes in EEG activity, other than where it indicates brain death tell us little about the process of death, other than that changes in level of consciousness are occurring.
The materialist position regarding brain activity and consciousness is one that is intuitively appealing, but not as unassailable as many assume. There are many, many threads on that subject.
The reports from mountian climbers are interesting - psychological proximity to death is without doubt important. It could be hypothesized that the individual may be experiencing NDE. The physical threat of death however is immediate and this does not apply to those with degenerative brain disorders.
I don’t disagree and my materialist (I don’t like the term materialist btw for a couple of reasons) idea of death is debatable, of course. But I never said that I think that degenerative brain disorders are more likely to have NDEs, just that they were closer to actual brain death. And I think I’ve shown that “psychological proximity to death experiences” are sufficient to explain some in-hospital NDEs. Let’s call them PPDEs.
