SKEPTIC:
If the "I" does, in
fact, survive bodily death, I'd like to know where the "I" goes under general
anesthesia. Where does it go during sleep (for those of us who don't recall
dreams)? Where
does the "I" go in someone who is in a coma? And is the "I" still the
same, fundamental spirit, for lack of a better term, if a stroke transforms
the personality into something totally different from what it was like before that stroke?
What I'm trying to do is to separate the "I" from the brain - if it's in fact
possible to do so. Unless it's possible to do so, then clearly the "I" is
annihilated at bodily death.
I work in a lab where we study human learning and memory
using functional MRI, and I spend a lot of time studying the brain and trying to make
sense of the various pathways and chemical processes at work. The more that I've learned,
the more that I've come to believe that who we are - the "I" - is an emergent
property of the brain. It's unique and unexpected, but at the same time, it couldn't exist
without the highly connectionistic pillars of the brain.
If you ablate area 17 of the
occipital lobe, you lose vision. Ablate
Broca's area, and you take out speech. If you
ablate the temporal
lobes, you take out morality. Ablate the frontal lobe, and you
radically transform personality, volition, and so on. What devastates this whole issue is
that we know that the "I" is a function of the physiology and neurochemistry of
the brain, so when the brain dies, what can possibly be left, aside from oblivion?
I was
deeply alarmed to realize that damage to the frontal
cortex
could produce a serial killer
like Jeffrey Dahmer. C.S. Lewis might as well have been on drugs when he said that each
human has a sense of morality which is God-given. Nonsense. Morality is conditioned into
the human organism, localized to the temporal lobe (along with religious concepts and
abstractions), and mediated by the frontal cortex of the brain. I was even more troubled
to reflect on the story of Phineas
Cage, who in a rail accident had a piece of metal
pierce his brain, and it caused profound (negative) personality changes. KEVIN WILLIAMS: Someone emailed to me the following comment concerning this remark by the SKEPTIC:
If you ablate area 17 of the occipital lobe, you lose vision. Ablate Broca's area, and you take out speech. If you ablate the temporal lobes, you take out morality. Ablate the frontal lobe, and you radically transform personality, volition, and so on. |
Rebuttal: If I ablate pieces of my television set, than I can distort the picture or stop the sound. But that doesn't mean the television set is the SOURCE of the images it displays (which we know it's not).
DR. KEN RING:
These are
philosophical or metaphysical questions, and they can't be answered definitively through
empirical research. However, on these questions, I have found the writings of
Paul Brunton
very helpful -- he wrote many books in the 30s, 40s and 50s, and they are still available.
These, however, are deep and thorny questions, and a great many philosophical perspectives
are already extant from which to explore them. Research of the NDE,
however, certainly suggests, but can never prove, that there is an "I" that is
independent of the brain, but whether it continues to survive intact after death is a
debatable matter.
DR. JEFF LONG:
One concern of NDE skeptics is the concept of a dual physical and spiritual life
presence, with the spiritual presence surviving bodily death. The physical presence is
easily discernable, while the spiritual presence is generally not easily discernable. It
is very helpful to personally have a NDE or NDE-like experience to
address such concerns. For virtually all near-death experiencers, a NDE
cures NDE disbelief. However, only approximately 4% of the United States
adult population have a personal history of NDEs. Others find they are
opened to the possibility of a dual physical/spiritual life presence through other
spiritually transformative life events.
These life experiences may include, but are not
limited to, markedly serendipitous events, other personal paranormal experiences, and
acceptance of other people's accounts of their spiritually transformative
experiences. I personally believe that if such spiritually transformative experiences are
sincerely sought, they are likely to be encountered. NDE research is
somewhat unique due to the subjective nature of the experience. This subjectivity precludes
certain conventional scientific methods of studying NDEs, such as
replicating NDEs or studying physical changes associated with the
experience.
This inability to study NDEs via certain accepted methods of
conventional scientific verification results in the need for some element of faith to
accept the reality of NDEs. I think this necessary element of faith is a
problem for many people in accepting the reality and significance of NDEs. Mitigating against this concern is the fact that
NDEs are
relatively common. Millions of people have had NDEs. NDEs are quite varied, but the consistency of the
NDE elements
(OBE experience, tunnel, light, meeting other beings, etc.) is striking. There is no
plausible biological explanation of NDEs. There is no other human
experience so dramatic, shared by so many people, and so relatively consistent in its
elements. The preceding suggests faith in the validity of NDE accounts
is the most reasonable conclusion from the evidence.
DR. ROBERT JORDAN:
On the
issue of general anesthesia, some individuals under general anesthesia are able to report
details of events occurring in the operating room such as what music was playing and what
the operating room personnel said - often to the embarrassment of those present. If
nothing can be recalled by the individual under general anesthesia, this cannot be
interpreted to mean that the "I" goes away. It may simply mean that the
person's ability to pay attention and to remember has been short-circuited. I work with
alcoholics who black out and remember nothing of their experience during the
black out. Apparently, when a person under acute intoxication blacks
out, the
neural pathways in the hippocampus and elsewhere, which are fundamental to retaining
memories, are not functioning. Nevertheless, they are able to act and think (too much!)
like themselves during that period about which they later have no recollection.
My understanding of the psychophysiological research on
dreaming is that everyone dreams whether they remember the dream or not. Often, people who
report that they don't dream, recall dreams quite vividly if they are awakened during
REM sleep.
Where does the "I" go when we have no recollection
of the "I?" This is a question with many possible answers. One possible
explanation is that the "I" disappears into the non-"I"-ness, which I
believe is the deeper reality.
I think scientists, if we possess any sense of humility, must
acknowledge that science cannot provide us with Ultimate Truth, only little hints of
understanding about how the Universe operates. Scientists are appropriately taught that
today's comprehensive theory is merely tomorrow's special case of an even more
comprehensive theory. Personally, I feel that I have learned more about what is really
true by meditating and thereby emptying my mind of concepts, rather than by creating
theories or doing experiments.
DR. PMH
ATWATER: Neither near-death research, nor any other type of scientific inquiry, can address this question.
I suggest you turn to spiritual or religious sources for clues. Actually, what you seek is
not contained within the providence of the mind, but only through the heart.
DR. STANISLAV GROF:
From
the NDE video, Life After Death (Episode
8, Wellspring Media), Dr.
Stanislav Grof had this to say about consciousness:
I had my training as a psychiatrist, a physician and
then as a Freudian analyst. When I became interested in non-ordinary states
and started serving powerful mystical experiences, also having some myself,
my first idea was that it (consciousness) has to be hard-wired in the brain.
I spent quite a bit of time trying to figure out how something like that is
possible.
Today, I came to the conclusion that it is not coming from the
brain. In that sense, it supports what Aldous Huxley believed after he had
some powerful psychedelic experiences and was trying to link them to the
brain. He came to the conclusion that maybe the brain acts as a kind of
reducing valve that actually protects us from too much cosmic input. So, I
don't see, for example, that experiences of archetypal realms, heavens,
paradises, experiences of archetypal beings, such as deities, demons from
different cultures, that people typically have in these states that they can
be somehow explained as something that comes from the brain. I don't think
you can locate the source of consciousness. I am quite sure it is not in the
brain – not inside of the skull.
It actually, according to my experience,
would lie beyond time and space, so it is not localizable. You actually come
to the source of consciousness when you dissolve any categories that imply
separation, individuality, time, space and so on. You just experience it as
a presence.
People who have these experiences can either perceive that
source or they can actually become the source, completely dissolved and
experience that source. But such categories as time and space, localization
coordinates, are not relevant for that experience. You actually have a sense
that the concepts of time and space come from that place. They are generated
by that place; but, the cosmic source itself, the cosmic consciousness
cannot be located – certainly not in the material world."
KEVIN WILLIAMS:
From what Grof said in the previous paragraph, changes to the
reducing valve function of the brain alters the way it reduces the cosmic
input to produce personality. According to Grof, consciousness itself is
not changed by such things as drugs and NDEs. It is
personality that is changed because personality is the product of the
reducing valve feature of the brain. As Grof theorizes, consciousness may not even be produced
by the brain, only altered. Interestingly enough,
reports of NDEs involve the experiencer feeling as if they
are expanding into the universe after death. This suggests that the brain
actually restricts consciousness to produce a personality. After brain
death, consciousness becomes unrestricted and the personality becomes pure
consciousness.
Many near-death experiences
involve the experiencer's consciousness expanding until it fills the entire
universe - even beyond. This experience has been described as literally becoming the universe by
near-death experiencers. This aspect found in NDEs
agrees with the astrological concept of the universe being an influence on
our afterlife sojourns. Here are some examples from NDEs to
demonstrate this:
Suddenly I seemed to be
rocketing away from the planet on this stream of life. I saw the Earth
fly
away. The solar system, in all its splendor, whizzed by and disappeared. At
faster than light speed, I flew through the center of the galaxy,
absorbing more knowledge as I went. I learned that this galaxy, and all of
the Universe, is bursting with many different varieties of LIFE. I saw many
worlds. The good news is that we are not alone in this Universe! As I
rode this stream of consciousness through the center of the galaxy, the
stream was expanding in awesome fractal waves of energy. The super clusters
of galaxies with all their ancient wisdom flew by. At first I thought I
was going somewhere; actually traveling. But then I realized that, as the
stream was expanding, my own consciousness was also expanding to take in
everything in the Universe! (Mellen-Thomas
Benedict)
The stars seemed to fly past me so rapidly that they formed a tunnel
around me. I began to sense awareness, knowledge. The farther forward I was
propelled the more knowledge I received. My mind felt like a sponge, growing
and expanding in size with each addition. The knowledge came in single words
and in whole idea blocks. I just seemed to be able to understand everything
as it was being soaked up or absorbed. I could feel my mind expanding and
absorbing and each new piece of information somehow seemed to belong. It was
as if I had known already but forgotten or mislaid it, as if it were waiting
here for me to pick it up on my way by. (Virginia
Rivers)
And in your life review you'll be the universe and experience
yourself in what you call your lifetime and how it affects the
universe. (Thomas Sawyer)
I was involved in this tremendous pouring forth of gratitude and joy and as that was going inside me, this white light began to infiltrate my consciousness. It came into me. It seemed I went out into it. I expanded into it
as it came into my field of consciousness. (Jayne
Smith)
I am love; I am understanding; I am compassion! My presence fills the room. And now I feel my presence in every room in the hospital. Even the tiniest space in the hospital is filled with this presence that is me. I sense myself beyond the hospital, above the city, even encompassing
Earth. I am melting into the universe.
I am everywhere at
once. (Josiane Antonette)
You must be ready to accept the possibility that there is a limitless range of awareness for which we now have no words; that awareness can expand
beyond the range of your ego, your self, your familiar identity, beyond everything you have learned, beyond your notions of space and time, beyond the differences which usually separate people from each other and from the world around them.
(Dr. Timothy Leary)
So you see, stage by
stage we expand into the planetary spheres, like light that has been
contained within a darkened glass, when finally uncovered and released goes
out into the boundless universe. The moral disposition we carry over
with us allows or prevents us from moving on in a conscious manner. Seeing
how we expand toward the stars and planets after death, it's no wonder we
look at the night sky in awe with feelings of reverence and maybe even
memories. (Rudolf Steiner)
After death, we expand into heavenly planetary realms. Our inward
spirituality allows us or prevents us from moving on in a conscious manner.
After this experience with the planetary realms, we fall asleep and the
cosmic forces act directly upon us preparing us for the next earthly
experience. Our cosmic rest regenerates us and prepares us for the time when
the desire to reincarnate starts to work on us. When that happens, we
begin the process of going back through the planetary realms picking up what
we will need from each in order to fulfill our purpose in the next Earth
life. (Rudolf Steiner)
I felt caught up in all
of this to the very depths of my being. I felt myself expanding and
expanding until I thought, "I'm going to burst!" The moment I
thought, "I'm going to burst!", I suddenly found myself alone,
back where this being had met me, and he had gone. (Margaret
Tweddell)
After hovering around New York,
Blackmore floated back to her room in Oxford where she became very small and
entered her body's toes. Then she grew very big, as big as a planet at
first, and then she filled the solar system and finally she became as
large as the universe. (Dr. Susan Blackmore)
[Webmaster note: Dr. Blackmore
believes her NDE was only a product of her brain much like a hallucination.
If she is correct, then NDEs are nothing more than a mass hallucination. The
problem with this is that dead brains do not
hallucinate. And even if they did, the brain cannot retain such
unconscious memories.]
KEVIN WILLIAMS:
The paragraphs above suggest to me that personality is likely a
function of the brain and dies along with brain death. But consciousness itself, unrestricted by the brain,
is everywhere and nowhere in particular.
Skeptics often rely on reductionism
to prove that altered brain function produces NDEs. But
they may only be defining the trigger in the brain that allows consciousness to expand to
produce a NDE. Using an analogy, we can reduce a television set to its basic components: circuits,
tube, transistors and wires. But we are unable to quantify the television
signals of the program, such as I Love Lucy as opposed to Jay Leno, by examining the individual components themselves. The
television signals of the program are not restricted to the television
set. They are located everywhere in the airwaves as well. When a television is turned
on (the brain is functioning), the components of the television processes the
signal (the brain alters consciousness) and creates a derivation of the signal,
a television program (personality).
Scientific evidence demonstrates that certain drugs can produce hallucinations in
the brain. Some scientists theorize that the same process
in the brain that produces hallucinations, also produces NDEs. But, Dr. Peter Fenwick, a
neuropsychiatrist and the leading
authority in Britain on NDEs, disagrees with this theory.
In the documentary, Into the Unknown: Strange But True, Dr. Fenwick explains:
The difficulty with those theories is that when you create these
wonderful states by taking drugs, you're conscious. In the NDE, you are unconscious. One of the things we know about brain
function in unconsciousness, is that you cannot create images and if you do,
you cannot remember them.
Dr. Fenwick describes the unconscious state
of the NDE:
The brain isn't functioning. It's
not there. It's destroyed. It's abnormal. But, yet, it can produce these
very clear experiences ... an unconscious state is when the brain ceases to
function. For example, if you faint, you fall to the floor, you don't know
what's happening and the brain isn't working. The memory systems are
particularly sensitive to unconsciousness. So, you won't remember
anything. But, yet, after one of these experiences (a NDE), you come
out with clear, lucid memories ... This is a real puzzle for science. I have
not yet seen any good scientific explanation which can explain that
fact.
[Webmaster note: So it
appears that we may never know exactly what a NDE is and
what produces them, until science can define exactly what consciousness is.
We may have a long way to go to learn this.]
SUSAN BLACKMORE:
I
think it is possible, in principle, to separate the "I" from the brain. The
brain is a physical object. The "I" is a construction - a story that a brain
tells, a fantasy that it weaves - an illusion of a real self who has consciousness and
free will. This fantasy is constructed all the time we are awake and our brain is
functioning normally. We are trapped in this fantasy world that seems to separate us from
everything else. Under anesthetic and near death this false sense disintegrates because
the brain can no longer build the story, but usually it comes back again. When we die, the
story stops for good - except in the minds of other people who knew us.
