Philosophy of the Conscious Mind and Near-Death Experience

Author:

Glenn Stok analyzes and writes about peculiar aspects of life, based on his studies of theoretical and critical philosophy.

consciousness-near-death

This essay is a research study of why we have so many documented cases of people with out-of-body experiences.

The accepted hypothesis among scientists is that consciousness originates in the brain. Therefore, if one is dead and detectable brain activity ceases, they can no longer be aware of their surroundings.

If this is the case, why do we hear of so many reports of out-of-body experiences (OBE) that people have during a near-death experience (NDE)?

Does our consciousness survive our death so that we continue in another realm, what many would call Heaven?

We'll examine the mystery of the documented evidence available in the medical field, but I won’t offer any confirmation since I haven't found any conclusive evidence.

Let's begin with the definition of both terms I'll be referring to in this discussion.

Commonly accepted acronyms used in this article:

OBE – Out of Body Experience

NDE – Near Death Experience

What Is a Near-Death Experience and an Out-of-Body Experience?

A Near-Death Experience (NDE) usually happens when one has a cardiac arrest or injury so severe that the brain’s functional ability is compromised.

It causes an out-of-body experience (OBE), a sensation of having left one's body and seeing things from elsewhere. Sometimes floating up and being able to view one’s unconscious body while witnessing a journey to Heaven, a beautiful place with spiritual beings, meeting previously deceased friends and relatives, and feeling a loving presence that could be considered God.

This phenomenon is so widespread with consistent descriptions that there must be a reasonable explanation for it. Why does one person’s NDE look so similar to so many others?

How Religious Beliefs Affect Near-Death Experience

Religious beliefs and expectations could influence the experience. People from various cultural backgrounds, do have slightly different near-death experiences.

There is no reason why Heaven must be a single homogeneous environment. After all, everyone should be comfortable with having an experience conducive to his or her well-being. Right?

Anyway, I've found in my research other examples of NDE where people experienced something totally unexpected and contrary to their cultural beliefs. But even in those cases, there was always a common theme of serenity and peace.1

Can Consciousness Exist Beyond the Body?

I had always believed there were good scientific explanations for the out-of-body journeys to an afterlife described by so many people who had a near-death experience. However, I never let my beliefs stand in the way of research. It was interesting to examine the documented cases.

I found numerous examples of out-of-body experiences where the experiencer (as they are called) describes in detail what went on around them during the time they were clinically dead, and the medical personnel confirmed these descriptions to be accurate.

Is that evidence of the survival of consciousness after death? Or are there other explanations for this phenomenon?

I just referred to the term “clinically dead” a moment ago. Before I continue talking about the possibility of consciousness after death, let's review how doctors consider a person dead.

What Is Death?

In the old days, doctors would declare a patient dead if they didn't detect any breath.

That was not very accurate and caused a lot of burials of live people. Do you know where the term "saved by the bell" originated?

A bell would be placed above coffins in graveyards, with a string passing through to the coffin. If the buried person wakes up, he or she can pull the string and ring the bell. A guard would hear the ringing during his "graveyard shift" and order personnel to quickly dig up the coffin.

Modern medicine has expressed different definitions of death, but still without any agreement to accuracy. For that matter, the definition of death is different in various countries.2

The following three criteria are the most common that is the best acceptable method practiced to determine death.3

  1. No cardiac output,
  2. No spontaneous respiratory effort,
  3. And fixed dilated pupils.

That is, however, all based on theory. One may still be alive when thought to be dead, and we are just using the wrong definition.

Modern medicine has reached the stage, in some cases, where people are brought back after all hope has been lost. Does this mean that doctors can bring a dead person back to life? Or does it mean that we’re still getting it wrong, and our criteria for determining death are still not correct?

consciousness-near-death

Is Death The End of Consciousness?

It's possible that those patients who are resuscitated and live to tell about their OBE were never really dead at all.

One theory that satisfies many scientists is that an OBE is simply a hallucination. The problem with this theory is that it doesn't take into account the accurate observations patients had during a Near-Death Experience (NDE), documented in hospitals all over the world.4

Can we say without a doubt that our brain controls our consciousness? And if so, does our awareness end when our body dies? Or does it continue in some form, such as our soul or our spirit?

I have studied many reported cases of NDE where people in a coma, or cardiac arrest, knew what was going on, not only around them but also with other people in their lives, not in their immediate presence while in a coma.

Maybe we are confused about all this because we don’t understand what consciousness is. We think we are conscious, but we can also program computers to simulate perception and make decisions. If our awareness is also merely a simulation, that might change our entire concept of consciousness.

The dictionary definition of consciousness includes:

  • The state of being awake and aware of one's surroundings.
  • The awareness or perception of something.
  • Awareness by the mind of itself and the world.

These are all clear explanations that satisfy our need for a definition. But they are all theories. Here's what I found in Wikipedia:

"Consciousness is the state or quality of awareness, or, of being aware of an external object or something within oneself. It has been defined as: sentience, awareness, subjectivity, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive control system of the mind."

— Wikipedia

Can Consciousness Be Transferred to Another Realm?

I mentioned above about reported cases of people in a coma, or cardiac arrest, knowing what was going on around them, and they were able to describe the perceptions accurately. Does this mean that their consciousness could leave their body and exist somewhere else in the universe?

Modern neuroscience proves that the brain cannot function without oxygen. That is obvious from the data of cardiac arrest patients. Monitoring equipment detects the absence of brain activity after blood is no longer entering the brain for too long. However, we have three criteria for death.

Without all three criteria to consider one dead that I mentioned earlier, it's incorrect to assume a patient has had an out-of-body experience while in a coma if he or she is not officially dead.

consciousness-near-death

"The issue is not whether there is any immeasurable brain activity of any kind whatsoever, but whether there is any brain activity of the specific form regarded by contemporary neuroscience as essential for the experience of consciousness. And there is no sign whatsoever of those specific forms of cerebral activity in the EEGs of cardiac arrest patients."

— Dr. Pim van Lommel, “Endless Consciousness: A Scientific Approach to the Near-Death Experience”

What Dr. Pim van Lommel is referring to is that an electroencephalogram (EEG) only monitors brain activity from the cerebral cortex, the outermost section of the brain.

It's possible that consciousness is still possible by being sustained by the more primitive sections of the brain that are not recorded by an EEG.5

It is well-documented, using electrodes implanted deep in the brain, that during prolonged cardiac arrest, with a lack of oxygen-rich blood to those parts of the brain, there is a reduction (or absence of) brain activity in those deep structures as well. Therefore one cannot expect to sustain consciousness.6

So, where is it? Where has it been hiding?

Flash Brain Function (Author’s Idea)

It's hard to say if consciousness requires a properly functioning brain. There is so much evidence that consciousness exists while in a coma.

Since I have a computer background, I am fully aware of how flash memory (as in USB memory sticks) can retain data without having a power source. So I thought it should be possible that our brain can continue to function at some primitive level without the required power source—namely oxygen-rich blood.

I would suppose that is possible only up to the point when the brain begins to decompose. That, of course, would be the mortal ending.

However, that conclusion is still only the case if consciousness is indeed a function of our brain. But what if it’s not?

Is Death Reversible? Reinstating Memories

The question that comes up now is this: is death reversible? If it's not, that means the words “resuscitate” and “death” are mutually exclusive. We can't use both in the same sentence.

A person is either permanently dead or has been resuscitated. If a patient was resuscitated, then he or she was never dead.

If this is taken as fact, then all the reports of people describing life after death, the light at the end of the tunnel, and similar descriptions of the afterlife, must have been hallucinations.

However, we still can't say that this is "a fact" at all. It remains a theory that consciousness requires an active brain. Therefore the only other theoretical explanation is that consciousness exists somewhere else.

Final Question: Does Consciousness Reside Outside the Brain?

We can all agree that the brain cannot maintain consciousness without oxygen-rich blood, based on the explanation I mentioned earlier.

Under these conditions, the brain is not functioning, and there is no recorded brain activity. The EEG is flat-lined. The person is considered clinically dead.

So what is Near-Death Experience? Are they conscious experiences of real events in another realm, or are they just imagined?

We still have to provide other reasonable explanations for Near-Death Experience, such as the following arguments7 by Dr. Neal Grossman:

  1. Lack of oxygen can cause hallucinations.
  2. It's the last gasp of a dying brain.
  3. People see what they want to see.
  4. Their vision of what was going on was simply a coincidence.

Yet, we still have to consider the evidence of all the Near-Death Experiences that are on record, which leaves us with the conclusion that consciousness must live outside the brain. But remember, that’s only a theoretical hypothesis.

A well-known neurosurgeon, Dr. Eben Alexander, experienced NDE where his brain was completely shut down. That was confirmed during his coma with brain activity monitoring equipment. He lived to tell about it, and you can read about it in my other article, Can Our Consciousness Continue After Death? based on my reading his book.

"It’s unlikely we’ll know the answer in our lifetimes, but that doesn’t mean we won’t keep asking."

— Dr. Eben Alexander, M.D. Neurosurgeon

Glenn Stok (author) from Long Island, NY on August 31, 2018:

Thanks Barbara. I had an interest in it a long time too. I researched it long before even thinking of writing about it. As you said, we can’t ever know for sure.

Barbara Radisavljevic from Templeton, CA on August 31, 2018:

A very well-written hub on a topic I've been interested in for decades. Thank you for researching it so well. I've read many books about death and NSE, but so far I still think it's true that with all the information we have, we still can't know for sure what we don't know unless we have faith that something is true. Then that faith is our assurance of what we believe is true.

Pori on August 23, 2018:

It’s quite easy to make assumptions and comments if one does not experience themselves. I’ve had two NDE experiences and lived to my age of 45 years old,even now I still haven’t come to terms why I returned.

What brought me back was the feeling of lose and intense emotions from my grandmother the first time and my Aunty in the second time.

As I watched them in different occasions begged me not to go.

I guess as a spirit we don’t lose our empathy.

Since that day I’ve carried the ability to feel people’s emotions.

Linda Crampton - Thanks for your review of my article. The subject is becoming even more interesting as I continue to investigate new research.

Fin from Barstow on November 24, 2017:

Interesting article with some curious arguments.

Linda Crampton from British Columbia, Canada on November 24, 2017:

This is a very interesting article, Glenn. You've written about a topic that has fascinated me for a long time. I've been exploring the topic myself. Thank you for presenting facts and ideas related to near death experiences so well.

Glenn Stok (author) from Long Island, NY on October 17, 2017:

Kari Poulsen - Thanks Kari. Your story goes along with the results doctors are beginning to notice. It’s very possible that our present definition of brain death is wrong, or that consciousness is not in the brain.

Kari Poulsen from Ohio on October 15, 2017:

Glenn, I think that our consciousness is energy. Energy cannot be destroyed, it can, however, change into something else. I think our consciousness lives on.

While I was a nurse, I cared for a woman who was declared "brain dead". I swore this woman's eyes followed me and maintained eye contact. Everyone else said I was crazy.

One day, the woman woke up. She remembered everything that went on during her "brain death". It was pretty amazing. :)

Glenn Stok (author) from Long Island, NY on October 13, 2017:

Jackie - Glad you lived through your coma. Two weeks! That's a long time. Not everyone has NDE though. Or like you said, maybe not everyone recalls the experience.

Jackie Lynnley from the beautiful south on October 13, 2017:

Saw you had written this at Nell's hub an decided to check it out. Very interesting.

I have had an out of body experience I believe when my father died, I went to be with him and help him through.

Strange, I once was in a coma and they said I would probably not live through the night but I remained in the coma two weeks or so and had no near death experience. Well none that I recall. I did live though. Hardheaded me.

Glenn Stok (author) from Long Island, NY on October 05, 2017:

FlourishAnyway - That's an amazing story about your grade school teacher. That shows how much has been learned since those days. And yet, we still have so much more to learn an understand about death.

The definition of death keeps being updated. That's why the medical field has so many cases now of bringing people back when they would have been pronounced dead already.

And consciousness is included in that list of things we still don't understand.

FlourishAnyway from USA on October 05, 2017:

That story about how we got the idiom “saved by the bell” was quite a frightening prospect. My ninth grade teacher used to tell the story of her birth. She was born at home and presumed to be a stillborn child so she was placed in a small towel in a shoebox under the bed until they could arrange for her burial. Those were the days when it was okay to bury a dead infant in the family plot. When they retrieved her from the box she was breathing. Eerie. It makes you wonder how many people have gone to their graves alive.

What neurologists know about the brain is only the tip of the iceberg. I’m convinced of that. As an MS patient I have personally experienced things that were supposed to be impossible but have been backed up by MRI evidence. It’s important for scientists to acknowledge what they still don’t know. The true nature of consciousness and death are among those things.

Glenn Stok (author) from Long Island, NY on October 05, 2017:

Tim Mitchell - Thanks for reading both of these articles Tim. I also find that my interest increases as I continue to do research on the subject. I find it most interesting that the medical community is beginning to show interest. But as you indicated, it's always important to question the cases that are being documented. I always try to dig deeper into the source.

Tim Mitchell from Escondido, CA on October 05, 2017:

Interesting article Glenn as well as the one you wrote on Where is Our Consciousness? I have a great interest in consciousness with on and off research. I have not read a book on it yet.

Frankly, sometimes it frightens me while other times I comfortable with it. That I believe is because of personal experience with OBE, NDE, and amnesia, which are catalyst of the interest. Anyway I think this article has motivated me to continue my quest to answer questions.

I think it is good that you are questioning to and forming your own hypothesis as a result. Keep on keeping on.

Glenn Stok (author) from Long Island, NY on October 03, 2017:

Heidi Thorne - I'm noticing a lot more research coming out on this topic now. The medical field is beginning to develop an interest in it. But we have to be careful with noticing the difference between fact and theory, as I pointed out at the beginning of this article.

Heidi Thorne from Chicago Area on October 03, 2017:

Great discussion of a fascinating topic! With the movie remake of "Flatliners" that just came out, it's certainly a topic on many people's minds.

I've read somewhere that there may be many levels of consciousness, and that it's not an on/off condition. I find that possible aspect fascinating as well.

Maybe one day we'll know what's on the other side (if there really is an "other" side). In the meantime, I'm looking forward to seeing more research on this.

Thanks again and have a great day!

Venkatachari - It's interesting to me too, even though I'm a skeptic same as you. That's why I felt the need to study both sides of the story. I find it amazing that there are so many cases where the NDEer is able to accurately describe what was going on when they were incapacitated.

Venkatachari M from Hyderabad, India on October 03, 2017:

This is very interesting. NDE and OBE are topics which make the news often in various magazines and among folks also. I heard of such stories even though I doubt all the stuff.

Thanks for bringing up this enlightening topic again. I would like to read your next article also.

Glenn Stok (author) from Long Island, NY on October 03, 2017:

Yvonne Spence - There are all kinds of stories out there. Unfortunately some may be made up.

It's best to go with the ones written by scientists and medical professionals who document their findings in their practice.

Glenn Stok (author) from Long Island, NY on October 03, 2017:

Jeanette Harris - I don't know what to believe either. That's why I wrote this article expressing both sides of the argument.

Even Dr. Eben Alexander, an NDEer who is also a prominent neurosurgeon, doesn't know what to believe—as you can tell from his quote at the end of this article.

Thanks for being interested and reading it.

Yvonne Spence from UK on October 03, 2017:

NDEs do fascinate me, so I found this very interesting. I've read about a few people who were seriously ill before a NDE, and woke up from it with marked recovery from their illness.

I also once read about a study that seemed to suggest people saw God based on their beliefs and to one man in this study, God wore Doc Marten boots and a biker jacket!

Glenn Stok (author) from Long Island, NY on October 03, 2017:

galleryofgrace - Oh, it's good to have feedback from a true NDEer. Thanks for chiming in with your experience. Yes, you indeed should write about it.

Jeanette Harris from 11996 Valley Falls Loop Spring Hill Florida, 34609 on October 03, 2017:

I don't know what to believe about NDE or out body OBE, I had read stories about this stuff.

galleryofgrace from Virginia on October 03, 2017:

As an NDE'er myself I have gone over these same questions at least a million times.

I was only 12 so the lifetime movie was pretty short. I did have a Christian background so this may explain why the beings that told me I had to go back all looked like extremely intelligent scholars. Dressed in white robes, they mentally told me I had to go back when I expressed concern for the care of my siblings and family.

I could write a book. Maybe I should, it has been an amazing trip.
