So when you say real do you mean something physical happens beyond mental brain processes in some afterlife or otherworldly dimension?
We're getting into metaphysics here, and that's where we deal with processes or phenomena "beyond physics". There's nothing wrong with that, but it's obviously not going to be conclusive. Yes, if the NDE reports are valid, and "something" happens beyond brain death then it's not going to be an observable phenomenon - yet. Which is why I mentioned that technology is being developed to try to determine if anything does happen beyond physical death. I know it sounds like science fiction, but it will be possible in the near future.

I think it can easily be agreed upon that some people have memories after an experience in which they are told they were brain dead/unconscious. I don't think it likely can be agreed upon that their memories occurred when the brain registered clinically dead/unconscious. I fail to see how it could possibly be determined that whatever people remember occurred when they in fact were clinically brain dead.
First of all, from the study (all emphasis here on is mine):
We included consecutive patients who were successfully resuscitated in coronary care units in ten Dutch hospitals during a research period varying between hospitals from 4 months to nearly 4 years (1988-92). The research period varied because of the requirement that all consecutive patients who had undergone successful cardiopulmonary resuscitation (CPR) were included. If this standard was not met we ended research in that hospital. All patients had been clinically dead, which we established mainly by electrocardiogram records. All patients gave written informed consent. We obtained ethics committee approval.

Certainly it is easy to appreciate that people previous to an unconscious state may have mental experiences similar in some ways to one another, which they may well remember later when revived.
This is obviously one of the most popular theories. From the study:
And yet, neurophysiological processes must play some part in NDE. Similar experiences can be induced through electrical stimulation of the temporal lobe (and hence of the hippocampus) during neurosurgery for epilepsy,23 with high carbon dioxide levels (hypercarbia),24 and in decreased cerebral perfusion resulting in local cerebral hypoxia as in rapid acceleration during training of fighter pilots,25 or as in hyperventilation followed by valsalva manoeuvre.4 Ketamine-induced experiences resulting from blockage of the NMDA receptor,26 and the role of endorphin, serotonin, and enkephalin have also been mentioned,27 as have near-death-like experiences after the use of LSD,28 psilocarpine, and mescaline.21 These induced experiences can consist of unconsciousness, out-of-body experiences, and perception of light or flashes of recollection from the past. These recollections, however, consist of fragmented and random memories unlike the panoramic life-review that can occur in NDE. Further, transformational processes with changing life-insight and disappearance of fear of death are rarely reported after induced experiences.

It does not. If I were convinced the cases were weak, I'd have abandoned study long ago, just like I have abandoned Book of Mormon "historicity". I'm not convinced, at this stage anyway, that near-death studies deserve to be put into the category of looking for Nephite civilisations.
marg wrote: What I want you to do Ray is accept that people can reject quite rationally the theory that there is some otherworldly after life phenomenon going on, without you thinking they are closed minded to do so.
And what I'd like you to do, marg, is accept that people who differ with your view on this are not necessary "gullible".
marg wrote: You are looking at this backwards. No one has provided any proof that death is not final. "Final death is the accepted presumption until proven otherwise.
Okay, would you like to do a survey of how many people believe in life after death? But I can already accept your rebuttal - it doesn't matter, because the majority isn't necessarily right. But let me take your argument a but further, marg. The "prove it" argument doesn't work in this case. We
already have data strongly indicating the
possibility of the survival of human consciousness beyond death. If you missed it, read the study. And there are lots more I can link for you. However, if you have already pre-determined that this
isn't possible, then your "prove it" approach indicates closed-mindedness. Data are there, but you choose to say, "I won't go to the data, let the data come to me". That's why scientists are proactively investigating this, because data
are there. So you can bury your head in the sand, or investigate.
marg wrote: This is one of these "issues" that I personally wouldn't involve myself spending much time on. For one I don't trust people's subjective anecdotal stories. You mentioned there is much variation depending upon a person's cultural background, that alone informs of the unreliability of their stories. So what is the benefit of spending lots of time reading about these experiences? Is it going to make any difference in the final analysis? Either there is an afterlife or there isn't. Whatever happens will happen irrespective of one's beliefs. Wishful thinking will make no difference.
"Wishful thinking" has nothing to do with this. I've already explained, marg, that data are available, data which challenge "accepted understandings". Why do you think Susan Blackmore spent more than 30 years studying parapsychology? Why did she not just sit back, sip on a rum-punch in a hammock and say "it's all BS"? Instead, she went on a quest to find answers to unsolved events backed up by solid but unexplained data.
marg wrote: According to the study you gave, only a small minority claimed NDE, the majority experienced no such thing. As I mentioned previously "final death" is the accepted presumption until overturned by evidence. And the evidence would have to be objective that the experiences claimed did in fact occur in an unconscious clincally brain dead state, that it wasn't due to wishful thinking, implanted memories, preconscious state remembered etc.
Once again, marg, this is all covered in the study by van Lommel, van Wees, Meyers and Elfferich. Three of them have Ph.Ds, and van Lommel is an MD specialising in cardiology. Maybe you should read how van Lommel became convinced that his many patients who referred to having "strange experiences" while clinically dead prodded him to study this much more, and not to rely on his
assumptions and then personal beliefs!

The skeptical position enjoys presumption and is the rational position without objective evidence indicating otherwise.
So if I was your friend and told you your house was on fire, and you need to get there quickly, would you tell me "prove it"?
