That's scientism to say that if science can't study it, we can't accept it. I don't subscribe to scientism myself.It's science. How do you determine if the experience of nde's occurred when the brain is shutdown? You can't. There's nothing to support that.
As much as materialists try to squirm out, the evidence of things like knowledge of events at a distance, knowledge of events while the brain was shut-down, etc. makes the materialist explanation so unlikely as to be ruled out in my opinion. For what my opinion is worth with you
These pilot studies to me, tell us that some of this experience is indeed triggered by brain trauma. That is consistent with my beliefs too.But we do know for a fact the same type of experiences can be, and are present whenever the brain is active in some degree. Pilots in training have the same experiences when exposed to extreme G forces, or people on certain types of drugs or whatnot that alter the mind to produce those same experiences. Each and every time, the brain is clearly active during these moments. There is no reason to really think otherwise. To say that NDEs occur when the brain is completely shut down..... No, I don't think so.
Except for a significant amount of anecdotal evidence from the actual experiencers. Not being a follower of scientism, I consider (meaning neither blindly accepting nor blindly rejecting) these things in forming my personal position.There is absolutely nothing that supports a notion that there is any NDE experience at the moment in time when the brain is shut down.
