Most of what people tell us about their sensory experiences is trustworthy. If this wasn’t the case we would be reduced to silence. This doesn’t mean that we just accept everything people say, it just means that most of what people relay to us is reliable; and since it’s generally reliable along with our sensory experiences it’s a genuine epistemological category along with other ways of acquiring knowledge. This way of knowing is much more pervasive than even science. It doesn’t have the glamour of science or the creative power of science, at least seemingly so, but its power in our lives is undeniable.
But, of course, you're forgetting that NDEs/OBEs are not sensory experiences, which consists of the usage of sight, hearing, smell, touch, and taste. All of those are caused by parts of our physical body. Dreaming, imagining, thinking, etc, aren't caused by any of our senses. These are the results of our brain processing. Consciousness aligns with the second category.
One can always point to counter-examples where large groups of people believed X and their belief or beliefs turned out to be false. However, this does nothing to the argument that testimonial evidence or our sensory experiences are generally reliable, which is the bedrock of NDE testimonials. If such examples diminished the effectiveness of the general reliability of such justifications, then it would also diminish sciences’ ability to be an effective way of justifying their beliefs or theories because science depends on testimony, sensory experience (observation), mathematics, and logic to validate many of their experiments. If you removed sensory experiences from science, it would collapse.
Wrong, it absolutely plays a pivotal role because belief(s) is the bedrock of NDE testimonials. As I already explained, sensory experiences are not evidence of NDE. Sneaking sensory experiences into belief testimonials does nothing to for the NDE argument. What it does do, is demonstrate the desperation and dishonesty of the argument.
My approach is simple, in that I’m applying Occam’s Razor to the evidence, i.e., the simplest explanation is probably the best explanation. This is how we approach most testimonial evidence in our lives. This is not to say that science isn’t helpful because it is, but that science is by its very nature materialistic, although that is slowly changing. Moreover, the tools of most scientists are not conducive to the study of consciousness because consciousness in my estimation is not materialistic, and this nonmaterialistic aspect can be understood with a simple understanding of our subjective experiences.
Actually, you're not applying Occam’s Razor because that's not what it entails. What Occam’s Razor actually entails; between competing explanations, the one with the
fewest assumption(s), is usually the correct one. Simplicity is not the hallmark of Occam’s Razor. The explanation for a globe earth is more complex than the explanation for a flat earth, but the flat earth explanation has a lot more assumptions.
The truth of the matter is that for many materialists no amount of evidence would convince them because they’re so entrenched in their beliefs. This is also true of religious ideology; no amount of counterevidence would dissuade them because they’re so dogmatically entrenched in their beliefs. Nothing seems to falsify such beliefs, which is mostly the result of dogmatism. Dogmatism in many cases is the enemy of truth.
This ad hominem attack on materialists does nothing to the argument(s) and/or people opposing the NDE argument(s) since there are non-materialists who are in opposition to the NDE position.
NDEs have the same structure that any veridical experience would have, i.e., they all show slightly different variations that fit the general structure of any veridical experience. This in itself isn’t strong evidence that the experiences are veridical, but it adds to the overall picture that the experiences are veridical. In other words, it’s exactly what you would expect from veridical experiences. Whereas in a hallucination, for example, you wouldn’t find the consistency of experience, nor the corroborative aspects (objective components) that you find in NDEs/OBEs.
This is simply what I called the "I'm not saying that it's aliens, but it's aliens" fallacy.
And, hallucination experiences can absolutely be more consistent than NDE. The Old Hag and the Shadow people are two examples.
Most people would consider sufficiently reliable the testimony of 10 or 20 people on most everyday events and would consider the need for science to verify such evidence as ridiculous. Of course, this depends on what people are claiming in their testimony. If 10 or 20 people are claiming they saw Bigfoot I’d be a bit skeptical, you’re going to need a lot more evidence than that, and you’re going to need much more corroboration along with bodies, bones, or other material evidence. The point is that different claims need more or less evidence depending on how much goes against what we normally experience. In the case of OBEs, we have millions of accounts, in a variety of settings, with thousands being corroborated, and the memories are as consistent or stronger than memories of other veridical experiences. These facts suggest that ordinary everyday citizens can, based on a cursory study of the testimony, conclude that OBEs do happen. I say that it’s enough evidence for people to claim that they know OBEs happen. I would further say that if you’ve had the experience, it’s perfectly reasonable to conclude that the experience was veridical, i.e., that you know it’s veridical. Case in point Dr. Eban Alexander’s (neuroscientist) NDE given here:
Now you're special pleading, testimonies for NDE is sufficient evidence to believe that it's true but testimonies for Bigfoot isn't.
To dismiss Dr. Alexander’s testimony, which in itself is very convincing, is to ignore very powerful experiences, that at the very least should be considered and studied with an open mind.
His testimony is neither convincing nor is it a powerful experience in regards to NDE. Studying his experience using his testimony should be done with an open mind and not blindly accept it as being strong evidence for NDE. That means that when studying his case, the information should consists of not only what was said in his testimony, but also information outside of it that is relevant to what happened. So, his background as a neurosurgeon, which is not a neuroscientist, has no affect on the validity of his claims.
One important piece of information should be noted and taken into consideration when examining his testimony and claims. Dr. Alexander was wrong about him being brain dead. It's a scientific fact, that a medically induced coma, which was done to him, is not brain dead. Although small, there is still some brain activity that is present.
