Why Do We Have Two Brains?

That’s semantic word salad, the sum is greater than its parts but there’s still one brain.

Foreword
Man is intrinsically good
and if shown good
will do good

Socrates

Know Thyself

Plato

What does “good” mean?
Can we accept that it has both a natural meaning
as well as a super-natural meaning?

Firstly - as applied to good social behavior
which we can examine and explain logically and objectively

Secondly- as applied to Go(o)dly religious behavior
which can only be explained intuitively and subjectively?

Let me put it this way
If we behave socially in a logical manner that is materially beneficial to our survival, like having a generous and caring nature; good personal hygiene; a good work ethic; good community commitment - and our actions do not harm or trespass on another being in any manner that might hamper theirs or our development -
we can tern that as “good” social behavior

On the other hand
If we behave in a manner that has no perceivable practical survival benefits

  • such as giving thanks to good health, praising a beautiful day or the beneficial rain falling on the crops; engaging in artistic pursuits - and we practice behaving in this thankful way regularly and preferably together within the congregation of our fellows - and in doing so making ourselves feel energized and motivated from within
    we can term that go(o)d behavior

Are these two types of “goodness”
from without
and from within
not what Plato meant when he urged us to “know” ourselves?

DUAL BRAIN DEVELOPMENT

Answering the question:
Why Science and Religion are of Two Minds

With all due respect to all the Ages of effort that has gone into the endless attempts to bridge the divide between science and religion and the countless great minds that have failed to do so:

The reason why this thesis pretends to prevail over all others is that prior to 1970 and the publication of results that have emerged from split-brain experiments, no other researcher in previous Ages had the dual-brain scientific data that is currently available.

Nor, it seems, has anyone else during the past 40 years since the publication of Professor Sperry’s Nobel Prize-winning thesis on split brain research and the research since then, seen the significance of introducing this modern understanding of how the human mind works into the mass education system which remains almost exclusively focused on left brain indoctrination.

Consequently no comprehensive philosophy or methodology exists that conclusively links dual-brain perceptions of analysis/intuition to the vital impasse between physics and metaphysics, which has divided Christian cultures with increasing severity ever since Aristotle parted with Plato, and all the masters before, by insisting that only the senses could perceive and analyze reality.
.
By explaining the exact nature of the relationship between the left and right hemispheres of the human cortex, this thesis proposes to bridge the argument between design and random effect, and thereby attempt to correct the disassociation which is confusing the child education process and, some would day, the gradual erosion of our ethical sensibilities.

It will provide a reason why two separate modes of perception had to evolve in the human brain.

It will show how and why human consciousness, including art and technology, could not have evolved beyond the rudimentary use of un-worked sticks and stones, evident among chimpanzees, without innate impulses of inspired ideation transmitted from the intuitive right side of the brain for analysis and application by the left side.

It will reveal how and why the intuitive side of the brain arrives at ideation.

It will provide a rational explanation as to why a subtle balance between practical survival needs and a universal Belief in super-natural ethical influence is an essential attribute of the human psyche

It will explain why the modern analytical side of the brain has come to reject the superstitious instincts of the right brain.

It will show why our ignorance of how delicately the psyche is balanced between the two brains, has set the specie on the path towards the possibility of irrational premature extinction.

                         ----------------------------------------------------------


Why is the Brain Split in Two?

There are several existential questions we need to ask ourselves
as to why we each walk around with two brains housed inside a single head

Why are two cerebral cortex’s necessary for our survival?
Do both brains work as one?
If not, what is the basic function of each brain?
How do we consciously access both brains?

If we can determine the precise evolutionary purpose underlying the need for having two brains
can we, then, evaluate the survival advantages of two separate modes of perception in a more comprehensive manner than we do at present.?

From that position we may be able to redefine the enigmatic dynamic of the human psyche – of being both objectively analytic and subjectively intuitive at one and the same time. - and thereby devise and introduce an entirely new methodology designed for a more holistic dual brain education.

Education

Forty years ago, science produced some extremely important experiments that distinguish the separate functions of each of the two hemispheres, which. surprisingly, have not been incorporated into the education system… We continue to concentrate almost exclusively on left brain analytical instruction and almost entirely neglect the intuitive inspirational potentials of the right brain, that place in the mind where creative ideas germinate and gives birth to sudden bursts of enlightenment.

Anatomically, we know from split-brain research that the left side of the cortex controls the motor reflexes of the right side of the body and processes mental perception analytically and that the right hemisphere handles the left motor reflexes and is the source of intuitive insights.

Left and Right Brain Modes of Perception

Intellect - intuition
Convergent - divergent
Digital - anagogic
Secondary - primary
Abstract - concrete
Directional - free
Propositional - imaginative
Analytic - relational
Lineal - non lineal
Rational - intuitive
Sequential - multiple
Analytic - holistic
Objective - subjective
Successive - simultaneous
J.E.Bogen
"Some Educational Aspects of Hemispheric Specialization "
in UCLA Education 1972

Though not conclusive there is some validity to the argument that the left and rights sides of the brain respectively represents the masculine and feminine principles of the individual psyche

Here are some insights from the I Ching or Book of Changes

Yin - yang
Feminine - masculine
Negative - positive
Moon - sun
Darkness - light
Yielding - aggressive
Left side - right side
Cold - warm
Autumn - spring
Unconscious - conscious
Emotion - reason

After examining data from his split-brain experiments
Professor Sperry made the following statement

“The main theme to emerge is that there appear to be two modes of thinking, verbal and non-verbal, represented rather separately in left and right hemispheres respectively, and that our education system, as well as science in general tends to neglect the non-verbal form of intellect. What it comers down to is that modern society discriminates against the right hemisphere.”

Roger W. Sperry
“Lateral Specialization of Cerebral Function
in Surgically Separated Hemispheres” 1973

In the forty years since then, neither the state nor private educational systems has done anything about that warning from the Nobel Prize laureate and tried to correct the imbalance. The main reason why is because nobody as yet has explained exactly what the value of intuitive input is or even why the brain is split into two separate modes of perception in the first place. Consequently nobody is certain how to devise the exact right brain exercises that could correct the imbalance.

One of Sperry’s disciples, Dr. Betty Edwards, devised a system of simple drawing exercises designed to excite the right brain into creative expression. She achieved almost instant success with all her beginner art students within a few weeks they progressed from initial childish sketches to astonishing minor master pieces. Since then her book “Drawing on the Right Side of the Brain” has sold several million copies and remains a perennial best seller

So we know, at least, that the right brain is home to artistic perspective and that with a little stimulus it responds positively and beneficially.

But we still do not know exactly how valuable or how vital that input is - not just in terms of encouraging a more holistic conscious development - but also in terms of how the output of both brains working in harmony could improve the general level of the human intelligence quotient and social behavior in particular.

This thesis approaches the conscious connection between the two brains by examining separately
Day Time Consciousness
Night Time Consciousness

to be continued…

Come on this is just bollocks no?

I’m not the one claiming that humans have two or three brains. But it’s interesting how the structure of the human brain reflects human evolution from earlier life forms.

Natural selection and evolution is interesting but only a human could imagine he had two or three brains.

That is natural deselection in action, or unnatural selection.

Exactly! And he imagines it because one of his brains is out of touch with the other! :astonished:

Thus schizophrenia thus intelligence, being able to imagine the future and remember the past is advantageous, yep so saying someone has two hemispheres is fine but 3 brains is pushing it a bit especially when most of us don’t use 90% of it ever.

Natural selection deselected 1 hemisphere long ago, it’s about time we started using both.

And this.
Which is also why we can do this:

Or at least some of us can

You mean all five. :laughing: But seriously I thnk that’s kind of Magnetman’s point.

five now is it well it’s better than SPoG from George hammond we had eigen vector number of brains. :unamused:

Multiple personality disorder doesn’t mean you have 12 minds. :stuck_out_tongue:

Solve:

If you can solve this it’s likely you will have used more than 10% of the one you have. :slight_smile:

A clue

Last time I checked there was little concensus among psychiatrists about the existence of multiple personality disorder. Those that believed it exists were a small minority.

It exists I should know I am both the Pope and The Sidhe and Napoleon oh and God obviously and of course thus The Messiah.

Gotta go curry for dinner!

The Inter-relationship between Day and Night Consciousness

Daylight Consciousness
The Analytical Mind

Throughout the daylight hours our basic animal consciousness is dependent on a constant analysis of in-coming data provided by the five senses. During the past two and a half million years as human population grew exponentially we have had to rely on increasing technological development for survival. In this process the sense of sight among our specie has become the dominant factor in almost all of our analytical determinations.

The Paramountcy of the Sense of Sight

Throughout the day light hours the familiar does not necessarily trigger a heightened degree of alertness in the psyche. Thus there is no need in the day to day business of survival to pause for inquiry in order to satisfy for one’s self that all is well. But any strange sound, scent, taste or touch has to be inspected by sight before the degree of alarm triggered by the unknown is satisfied by the known, allowing the calmed psyche to return to a state of security.

The evolution of our superior intelligence, driven as we have said, to higher levels by the manufacture of artificial technologies designed to increase our survival potential and comfort level, has made reliance on our eyes the paramount factor in daily consciousness. Since we take sight consciousness for granted, the importance of its limitations needs to be emphasized: This almost exclusive dependence on sight as the prime consciousness assurance among our specie has subordinated the other four senses well below the level of other animals. Among the blind, constant exercise and reliance on their four functioning senses make them consequently sharper than normal. Experiments under hypnosis reveal that, in general, the latent survival capabilities of our subordinate senses remain as sharp as those of other animals.

Invention: How does it arrive in Consciousness?

In the humdrum business of daily survival needs, analytical consciousness in itself could never have progressed beyond the mechanics of foraging for a living. Our brains would never have evolved beyond the basic primate stage if intuitive impulses of creative intelligence did not filter into left brain consciousness for analytical consideration. Without the input of those mysterious ideations and inspirations the human-definition of a self-reflective consciousness would not have emerged from Nature. We would have remained, at best, as unimaginative hominid primates, surviving like other animals, using primitive unworked tools on occasion, not much further advanced than chimpanzees.

Who we are today is the result of the first two mass evolutions of consciousness: First from animal foragers into large-brained Stone Age hunter/gatherers who, over tens of thousands of generations of application, mastered the mechanics of tools, weaponry, snares, traps, nets – and in that process imprinted the physics of tension, torque and trajectory into the human gene pool: Then, secondly, investing almost another thousand generations in a Bronze Age as farmers - domesticating Nature, developing agriculture into a fine art, and thereby laying the foundations for today’s advanced technological cultures. None of that would have happened if some mysterious inventive impulse had not stimulated the basic analytical survival mode.

So what was the nature of that innovative impulse?
What made it arise?
Exactly where does abstract ideation originate?
Why should we get subtle signals; “hunches,” premonitions; creative inspirations?

The Source of Invention

It is reasonable to assume that the source of all such inspiration can only be coming from the intuitive right brain, that subjective side of human consciousness that all the kings men and all the psychologists on the planet still know almost nothing about. It is listed as the vast dark area of the sub-conscious, who’s depths, it is said, we will never plumb. It is this subtle realm of the imaginative side of the brain and our inability to definitively explain its reason for being, or define how and why it evolved as a partner to the left brain, which confounds empirical analysis and causes massive self-doubt among societies and allows science to dismiss the profundity of its metaphysical influences.

Night Time Consciousness

Its fun to assume but is it empirically verifiable?

Contribute
or pipe down Sidhe
babble belongs on another thread
I am willing to listen to anything constructive
exactly what am I assuming or sounds illogical?

:unamused:

In that case prove it?

Otherwise Magnetman you are just George Hammond lite.

Thank you
I will continue to try my best
where greater minds than mine have failed

After a life time of searching among the collective psyche
as well as within the microcosm of my own
I think I have stumbled upon a simple explanation
as to why the two brains are out of sync

I sincerely believe that as we go along
you will agree that I may have found a possible solution
to the impasse between science and religion
one that is so obvious no one else has seen it

Before continuing
Any constructive comments or questions at this time are welcome


Night Consciousness

The Intuitive Mind

As an essential (and indeed pivotal) part of their dual-brain training, when each of my children reached their teens I encouraged them to engage in an ancient African pubertal ordeal and rite of passage. I asked them to spend two or three days alone and unarmed in the mountain wilderness in order to experience night consciousness in its natural state. I wanted them to bring that ancient sense of how darkness affects the psyche to the forefront of their minds,

For the past 6000 years or more of civilized existence and technological development, especially in terms of bringing artificial light into the night, the fear-filled nature of night consciousness has been gradually driven back into the depths of our sub-conscious… Along with that technologically manufactured sense of artificial security we have scoffed at the superstitious fears of our earlier ancestors and more or less labeled them as superstitious primitives. But the fact is, every child born remains afraid of the dark, and easily believes in fairies, goblins, ogres, imps and Santa Clause and requires much encouragement to push such “nonsense” to the back of their minds

Night consciousness is exactly that – non-sense. In the wilderness, the five senses of the day that feed us familiar reliable information and make us feel secure, begin to fade at twilight. Sight, so dominant during the day, begins to play tricks with the mind. Moving shadows take on ominous shapes. The familiar sounds of the day of winds and birds and animals moving are now replaced by the unfamiliar sounds of the predators of the night. The cough of a leopard, the insane giggle of hyenas, the screech of an owl and the unearthly death screams of their victims. The analytical side of the psyche cannot deal rationally with this incoming stream of fear-filled information.

In the dark when sight is not only the subordinate sense, but also subject to distortion, consciousness is abruptly left without its prime determinate. With its other senses dulled via the evolutionary process of becoming human, the basic psyche is left in a state of fear and unease. Any psychiatrist will affirm that no psyche can remain in a state of constant fright every night of its life and not go insane from unnamed fears, sleeplessness, nightmarish dreams and exhaustion. Something has to reassure our safety in the dark. We have to know that despite the distorted information received from our senses at night, we are more or less safe from harm. There has to be some form of instinctive feed-back keeping night fears at a manageable level.

In short, the powers of imagination have to come to the rescue.

It is here in this primitive, long- forgotten piece if human understanding, that the survival need for intuitive side of the cortex provides a reasonable motive for being. It is in the unfathomable depths of the intuitive mind that the ancient animistic superstition of an invisible Universal Consciousness is sensed. It is here that the shaman medium encounters spiritual inspiration. It is from this ancient instinctive belief in the essential benevolence of super-natural forces warding off evil and misfortune, that all the major religions of the world took form.

The reason why we are so skeptical of religious belief today is not because we are more intelligent than our ancestors, but because we have gradually driven back our fears of the night via increasing mastery over the darkness of the night. Our analytical mind is kept reassured, prior to sleep, via artificial light, security walls, weapons and police patrols of protection.

In reality, our superstitious fears are not primitive non-sense. Their imaginative powers remain as real and vital today as it has they have always been, Spend just one night alone and vulnerable in the wilderness and experience it for yourself.

Without that imaginative side to our nature, spurred into action by our superstitious fears of the dark, our first human ancestor who tried to take command of the dark, would never have thought to simply take a daylight digging stick and keep it with him as a weapon at night – and from that first basic technological idea of improving our survival chances - move us all the way to the electric light.

Thus science, which scoffs at religion, is actually its beneficiary.
We did not invent the idea of God. We were born with it. It is that Divine protection that kept us alive in the dark.

Science and Religion

An objective examination

Science and Religion
An objective examination

Other than arguments that appeal to our common sense
like the day/night consciousness argument just presented
there is no rational explanation for the belief that an invisible omniscient godhead exists and exerts a supernatural influence on creation.

Thus science, unable to produce proof that conclusively disproves the existence of a Divine Consciousness is, by its own criteria, forced to ignore it, and in this sense, tacitly denies that there is a God and perforce labels such belief as primitive.

This scientific refutation has caused endless confusion among all human societies, major and minor, who have all based their cultures on the Divine premise in one way or another. It has created serious disharmony in the home, in public education, in politics and on the market place. And since science is the prevalent common denominator that links all cultures to the same intellectual mind-set via the global school classroom - its refusal to accommodate religious belief makes it indirectly responsible for the on-going wars and jihads between competing religions.

Since all human societies, from Stone Age Animism onwards into the present, many of them separated by vast distances in time and space, have individually embraced a spiritual tenet of one kind or another as a fundamental factor in their social organizations - the basic reality that has to be accepted by science, whether it is considered to be primitive or not, is that this universal belief in supernatural phenomena is an indelible, instinctive, characteristic of human nature, which cannot simply be banished by appealing to rationality while ignoring instinct…

As argued in this treatise
It is not unreasonable to assume that this universal claim to extra-sensory perception has to be an inspirational attribute originating in the intuitive side of the human brain and that this imaginative input has vital evolutionary survival value.

So the salient question then for both science and religion
is not whether or not God exists
or who He/She/It is
but why have we have always sustained an ingrained belief in supernatural influences?
What is its meaning and purpose?

Let me answer this by an event that happened back in 1966

A light plane carrying four young scientists experienced engine failure
and had to make a forced landing in the Kalahari Desert
several hundred miles from help.

five days later
all four young me were found dead
they had obviously decided to split up
and gone in search of help in four different directions
none had gone more than ten miles from the downed aircraft
the police report stated that they had died from dehydration and exposure

but did they?

The Kalahari is not a pure desert
though there is only surface water for a few weeks of the year
the sandy soil produces a a wealth of vegetation
large camelthorn trees for shade
wild berries, succelents tubers and roots
it is home to a huge herds of wildebeeste, giraffe, baboons, rodents, reptiles
including their predators, large and small
also
2,000 Bushmen hunter/gatherer family groups lived there for millennium

even the most naive can survive there for a few weeks at least
even without more than the moisture one suck out of a root
the shelter one can make out of grass and twigs
and no food

so what killed four intelligent young scientists so quickly?

I put it to you that they died
because of their lack of faith in a guardian God
of their inability to access the spiritual comfort of the right brains
thus they died of panic and loneliness
of their fear of the night

as do hundreds of other moderns who die when stranded in the wilderness every year

Interesting theory MM, but can you show any scientific studies, evidence or evolutionary theory to back this up?

It seems that fear of the night would simply be met more easily by fortifying one’s territory and setting up a few members of the tribe as night watchmen. While your idea is interesting (without any scientific literature it just remains an idea, pure speculation) I see no reason to assume that such simpler social methods would not mitigate the psychological effects of loss of primary sensation (vision) at night.

Got anything to back up your ideas here?

Thanks, I always hope to arouse interest in the mysteries of the right brain,
if the interest is honest and open-minded enough
that is the beginning of more serious internal questioning as to the source of one’s own attitude to life and what it means
rather than just relying like a school child on data collected by others and spoon-fed to you.

What got me going back in the early '70’s
was a challenge from an internationally recognized metaphysicist who also held a degree in nuclear physics
He asked me to try and sit down in a quite place and still the endless internal dialogue of the left brain
I was to try for five minutes and not allow a single unbidden thought to interrupt my powers of concentration
try as i might, I could not even manage one minute without my mind drifting off on an extraneous thought
(it is said we have some 60,000 of them daily)
it was that failure to master my own mind that set me off on a life long search
to find the source of my own thoughts

There are dozens of studies which prove that the vast majority of moderns continue to believe in God
Of course none which prove that a God exists or who He/She is
6000 years of circumstantial evidence from all walks of life in every culture
is hard to dismiss out of hand
man does not build massive temples, mosques and cathedrals on a whim
it is something more than just money which has inspired the great wealth of religious art, music and writing
that defines our cultures
Tens of thousands of personal testaments regarding Divine encounters
can be brushed off a mental aberrations if you prefer that approach
but who is to say you are right?

[/quote]
My own first sortie into the realm of metaphysics
was to produce a television documentary on shamanism for the South African Broadcasting Corporation.
My guide was Dr. Adrian Boshier, director of the museum of Man and Science in Johannesburg.
Over one thousands shamans still practiced their ancient psychic healing arts in Soweto at that time,
most of them females.
My study which focused on the question: how and why does one become a shaman?
The documentary clearly v revealed that their intuitive powers are undeniable
example:
A Zulu shaman named Robert Shabalala accompanied Boshier on a tour through a psychiatric hospital
in every ward, without asking question, Robert pointed out every schizoid and hysteric
both still considered by western science to be incurable conditions
Robert claimed that they were potential shamans
that they were suffering from spiritual frustration
that he could cure each one within three months
of course none of the doctors on the tour believed him
and those souls remain locked up
The question is was
How did Robert recognize them instantly?

In another example
we filmed a female shaman diagnose the illness of over seventy patients
without asking for a symptom
she sucked bits of bone, shells, wood and plastic
out of tiny incisions she made in the skin place the place of their ailments
in each case her diagnosis was spot on
two of her patents were from my own film crew

After broadcast viewers claimed that she had previously swallowed the “psychic” objects
and regurgitated them each time
that may be true
but that did not explain how she knew where each patient felt their pains
Her empathetic reply:
“I feel it myself”

In one case Robert Shabalala had to be hospitalized with pains in the stomach
three days before his patient suffering the same pains showed up

All those super-natural circumstances are recorded on film
I have no proof of how they did it

40 shamans were featured in the documentary
all had apprentices staying and studying with them in their homes
all the training focused on right brain drills and exercises
usually lasting three months

In one of the training drills we filmed
my cameraman hid a coin in the frame of one of the film lights
a young neophyte of about 16 was brought in
he knelt in silelnce for a few moments with his eyes closed
then found it immediately

Since then I have spent decades practicing right brain drills
my first spiritual reward was to awake one morning
with a sudden feeling of deep affection for the brotherhood of humanity
my IQ has jumped several points
my previous amateurish attempts at art have matured into professional drawings
my atonal singing voice has found pitch
my dreams have been immeasurably enriched
my sense of personal integrity is vastly improved
any trespass is immediately rued
I am totally unable to be swayed to left or right by any political ideology
and remain centered in my judgments

For the past twenty years
I have passed this dual brain training on to eight of my children
the social rewards are outstanding
the spiritual rewards are super-natural
