PERCEPTIONS OF REALITY
This installment appears a few days earlier than usual
because we will take a week of vacation visiting the Caribbean.
As the November elections finally draw nearer the American
public is deluged by claims and counterclaims from the two major parties. These
tend to leave the average citizen in a state of bewilderment, unless one is a
faithful party hack who does what one is told. But for those of us who like to
think for ourselves the question of: what is fact and what is fiction? does become important. I shall deal with the dilemma of the
American voter, which results from this problem, in next month’s installment
and intend to limit myself here to how we perceive reality or, if you like, the
truth. This is the fundamental issue from which all else flows.
In May of 1980 I published in The Journal of Nervous and Mental Disease an article on, “The
Reality of Death Experiences. A Personal Perspective.” It was prompted by a rash
of publications on near-death experiences, which were taken as proof for
survival of the soul after death. The question whether we are simply
electro-magnetic-biochemical machines, which have to decay and perish, or
whether there is an additional element in the human being which survives the
destruction of the body is obviously important for how we conduct ourselves in
our lives. Inasmuch as the idea of “ashes to ashes” as the end all and be all
has always been unpopular, religious thinkers and philosophers have come up
with various models of an afterlife. In our skeptical and agnostic society
these ideas have lost credence because scientific evidence for retention of
consciousness after destruction of the brain is lacking. The near-death
experience by survivors of catastrophic life situations was, therefore, hailed
as the long sought proof. Reputable physicians and psychologists published
books on the narrations of these obviously sincere people who stated that
during the time when they were regarded clinically dead, or were in extreme
life-threatening circumstances, had been aware that they
had died. They were welcomed by deceased relatives or other helpers, but were
eventually told to return to earth, which they reluctantly agreed to. The
near-death experience (NDE) had all the intensity, if not more, of waking life
rather than dream consciousness and became the ultimate reality for the
particular person. It affected future conduct because fear of death was lost
and the people directed their lives with foremost regard to the benefit of
others, rather than strictly selfish purposes.
I would not have written the article had I not experienced
earlier in life the knowledge of, “I am dead, I am free,” accompanied by an
indescribable feeling of bliss. The circumstances under which this arose are
detailed in the paper (reprint available on request) and need not be repeated
here but the important aspect is the word “knowledge.” I did not “believe” that
I was dead; I “knew” that I was dead and it was wonderful. The subsequent
awakening in a hospital bed, wracked with pain, was a severe disappointment. I
never talked about it to anyone except for my wife, Martha, who stood at the
bedside and heard me say as my first words, “let me die, let me die.”
The experience convinced me that the people who claimed to
have had a NDE were indeed truthful and had experienced something that is out
of the realm of the ordinary; but it also demonstrated the fallibility of human
knowledge. The knowledge of that moment, which I will remember for the rest of
my life, was wrong because I had not died I only thought so. Life altering as
the experience was it also confronted me, as a neurologist, with: what do we
call knowledge or reality? If absolute knowledge, experienced as beyond any
shadow of a doubt, can subsequently be proven patently wrong it behooves us to
look for the reasons. I tried to come to grips with the problem in the
mentioned paper because it was obvious that the NDE phenomenon cannot be taken
at face value for survival of the soul after death. Although the experience occurs under clearly
altered brain function, the brain is not dead and the question what
consciousness, if any, survives a dead brain remains unanswerable.
This problem is, however, not urgent and is likely to remain
unsolvable in the foreseeable future. The question of how we perceive our
internal and external environment can be examined, however, and conclusions can
be drawn. In the mentioned paper I made a distinction between: subjective
reality, shared subjective reality and objective reality. In my own situation I
was dead subjectively but alive objectively to everybody else. Thus, subjective
and objective reality can be vastly different and should not be confused. In
everyday life we tend not to make this distinction. Subjective impressions tend
to be relegated to dreams, daydreams and fantasies and we act as if they were
unimportant. The fact that our subjective reality, unconscious bias resulting
from previous life experiences, flavors how we perceive objective reality is
only rarely fully acknowledged. We believe that we act on objective reality, or
facts, when we actually conduct our lives on shared subjective reality. This
fundamental point needs to be grasped and kept hold of.
As mentioned we like to think that we conduct ourselves in
an objective, dispassionate, manner most of the time, but this is a fallacy.
Unless we are engaged in a specific task which requires fullest concentration
our thoughts wander into daydreams and fantasies.
These tend to reinforce each other and provide the background for how we meet
the next life situation. Thus the
question arises: how do we know when something, anything, represents objective
reality? The term is defined here as an observable fact, which does not involve
judgment, and is verifiable by anyone with a healthy central nervous system who
uses the same means by which the particular fact was arrived at in the first
place. For instance the content of this essay is my subjective reality, which
you may or may not share, but that it contains a definable number of words can
be verified by anyone and is objective reality. This is, of course, what
science strives for but this is not how we live our daily lives because it
would require pure reason and that commodity is not readily used by the human
being most of the time.
This brings up another question: how do we know what we
think we know? As a result of the experience mentioned above I began to examine
my thoughts in the waking as well dreaming state rather carefully and the
result was quite surprising. In general we do not accord to dreams the same
reality as to waking consciousness. So: how do we know that a dream is “only a
dream” rather than waking reality? Recently the movie “Oh God,” with John
Denver as a supermarket assistant manager and George Burns as God, was shown again on television and I was struck by the
following conversation:
Denver: “How do
I know that you are real and I’m not just dreaming this?
Burns: “What color are my eyes?”
Denver: “Blue”
Burns: “Do you dream in color?”
Denver: “No.”
Burns: “So, there you have it.”
Well, for me and some others this type of reality testing
would not work as the following example shows. I dreamt that it is a Saturday
morning. I am heading down the pier at the marina to my sailboat to get ready
for the race when the thought hits me, “could this be a dream?” Then I look up
and say to myself, “No; the sky is so blue, the clouds
are so white, I feel the wind on my cheek; this can’t be a dream.” When I woke
up eventually I found out that it wasn’t Saturday after all and I had to go to
work. Thus, this type of reality check doesn’t work. With continued examination
of my dreams I found out that during the dream it is impossible to draw a
distinction between waking and dream consciousness. Whatever test one may
devise is futile as another example shows: It is a Thursday afternoon and I
find myself walking around in my neighborhood rather than being at work. I have
no memory whatsoever why I am not a work and this raises serious concerns. The
neurologist then confronted himself with two possibilities: either I have a
serious brain disorder or I am dreaming. I concluded that I was dreaming, woke
up contentedly in the knowledge of having dreamt and got up to shower. But even
this was merely a continuation of the dream as I found out when the alarm went
off at 7 a.m.
There are also sometimes so called “lucid dreams” where the
dreamer realizes in the dream that he is dreaming. This has happened to me on a
few occasions and was actually quite hilarious. For instance: I am talking with
a group of people when the knowledge hits me: this is a dream! I then proceed
to tell the bystanders that they don’t really exist; they are just pictures in
my brain. You can readily imagine the expressions on their faces that resulted.
This fundamental fact of life that we cannot tell during the
dream whether we operate on dream or waking consciousness has profound
repercussions for our last moments of life. The distinction that “it was a
dream” becomes apparent only upon awakening, but when we die there is no awakening,
at least not on planet earth, and whatever pictures our brains choose to
conjure up during the process of dying will be taken as objective reality
although it exists only in our heads. This leads to the remarkable conclusion
that we are indeed immortal to ourselves. By definition the human being cannot
experience unconsconsciousness. Even if the thought, “I am unconscious” were to
occur it would be a conscious experience. Since we are subjectively immortal to
ourselves the content of consciousness during our dying moments may be of
crucial importance but that is for each individual to ponder about.
The reason why we cannot distinguish objective from
subjective reality in our dreams is probably due to relative absence of
activity in what is called the prefrontal lobes. These portions of our brains
are the latest acquisition in human development and are present only to a rudimentary
extent in the monkey. They endow us with foresight, judgment, concentration,
critical thinking and what is generally called executive function. The
prefrontal lobes, rather than the rest of the brain, enable us to act
potentially as Homo sapiens. The tragedy of the human race is that they are not
always put into gear. We tend to operate on automatic pilot and this is where
perception comes in.
When a sensory impulse travels from its specific peripheral
receptor organs via specific pathways to the specific central receptor stations
it does not remain there but gets subsequently relayed to a variety of other
brain structures. These may or may not allow the sensory impression to reach
consciousness. It could be shown experimentally that there are two types of
responses in the brain to a peripheral stimulus. These have been called the
primary and the secondary. While the primary is limited to the specific brain
sensory area, the secondary response is widespread and can be changed by
conditioning. Pavlov has shown this in his animals more than a hundred years
ago on a behavioral level and we can now study its electrophysiological basis.
Conditioning is not limited, however, to producing salivating dogs at the ring
of a bell but goes on constantly in our brains. This is how habits are formed
and this is the grist for the mill of politicians who want to us to think the
way they do. Conditioning proceeds in an entirely unconscious manner and there
is nothing we can do about it unless we are fully aware that it is indeed
happening to us. Once this insight is reached we can act in a rational rather
than impulsive, conditioned, manner. We stop being, in the words of our
President, “gut-players” and put our prefrontal lobes into gear.
How can this be done? Buddhist philosophy provides the
answer. The seventh point of the “Eightfold Noble Path” is “Right Mindfulness.”
I have always had a problem with the precise meaning of the term until I came
across a book by Nyanaponika Thera. The
Heart of Buddhist Meditation (available on amazon.com) is a superb example
of how a Ceylonese monk, who explains two thousand five hundred years old
thoughts, can benefit modern Americans. The first and most important aspect is
the effort needed to “Know Thyself;” an admonition which also graced Apollo’s
temple at Delphi. Only when we understand how we as
individuals operate can we hope to understand others by noting the similarities
and differences. To achieve this goal the Buddha has proclaimed the “Four
Foundations of Mindfulness.” They deal with the accurate perception of one’s
internal world. Namely: one’s body, one’s feelings, one’s state of mind, and
the pictures the mind produces. Once this has been accomplished one can deal
appropriately with the external world. For the purposes of this essay only the
first three aspects dealing with action will be discussed at this time. These
are: bare attention, clear perception of purpose, and clear perception of
suitability of means for achieving that purpose.
Bare attention exhorts us to register only the primary sense
impression without jumping immediately to the conditioned secondary responses
which are judgmental. For instance when one is stuck in traffic one is not
supposed to get exercised over the consequences of being late to wherever one
is headed but instead register the fact and direct one’s attention to the car
ahead of one. Its color, its make, its license plate and so on can be examined
in detail. All of this is to be done in a objective
way as if one were expected to report it to someone else. In essence: look at
each event as it occurs with a scientific, detached mind and move on when the
situation changes. Immediate judgment, which is the conditioned response, needs
to be held in abeyance. This is also what “living in the present” really means.
When a new action needs to be initiated, the second principle ought to be
adhered to and one should ask oneself immediately: “what is the purpose?” Once
that question has been examined and a decision has been made to move ahead the
final question arises: are the means to be employed to achieve this purpose
really appropriate?
When we look at our world in this manner we can immediately
see how wrong the Bush administration’s response to the 9/11 tragedy was. Had
our leadership been reared on the above stated principles instead of the Old
Testament they would have spared us and the world untold suffering. Bare
attention would have registered as: Two buildings were completely destroyed,
one partially, four commercial jets were lost and nearly three thousand people
were killed. Those were the facts and our so-called Judeo-Christian heritage
cried out for vengeance. Not on the people who actually committed the crime,
because they were dead already but on those who had sent them on their mission.
Some response was obviously required and this is where the next two aspects of
mindfulness should have come into play.
The prime purpose of a reaction should have been to a)
compensate, to the extent possible, the victims and b) take measures that will minimize
the chances of a recurrence. A fund for the victims was indeed set up but the
measures to prevent a recurrence did not take “suitability of means” into
account. The appropriate means to deal with bin-Laden’s
organization would have been through international cooperation to deprive it of
its finances, as well as limited specific special forces operations to destroy
his sanctuary in Afghanistan, and make life difficult for him, wherever he
moved to subsequently. Only the financial route was pursued but for the rest
ulterior motives came into play. The Taliban regime had to disappear and for
good measure the whole Middle East has now to be turned
into reliable American satellite states under the name of democracies. Clear
perception of purpose and especially “suitability of means” would immediately
label these fantasies as serious delusions.
This brings us back to shared subjective reality. Since the
vast majority of the American public has only limited awareness of Buddhist
thought it can easily become prey to propaganda which feeds feelings of
vengeance, fear, and pride. Our reality is not supposed to be dominated by
rational thought but by emotions and conditioned reflexes. This is the true
evil in our society and it will destroy us unless taken cognizance of.
The next two months may become some of the most dangerous in
the history of our republic. If the “swift boat” attack on Senator Kerry
misfires, Karl Rove may yet push for some Iran
mission to save his boss’s re-election, or engineer some homeland disaster. The
way he has been described is that for him winning is everything and defeat is
“not an option.” The book Bush’s Brain by
James Moore, which depicts the workings of Rove’s mind, has now been made into
a movie and one hopes that it will be widely shown. Only when the bright light
of public awareness is directed into the murky shadows of the corridors of
power, where policies are hatched in secrecy, can we hope that a more reasoned
approach to world affairs will emerge. In this way reality perception will
stick closer to observable facts and we can rationally develop proper solutions
to our problems.
