Origins of Human Aggression
(pg.29) - MacLean
The human brain evolves and expands along the lines of three basic
patterns characterized as reptilian, paleomammalian, and neomammalian.
"Radically different in chemistry and structure, and in an evolutionary
sense countless generations apart, we have, so to speak, a hierarchy
of three-brains-in-one, or what may be appropriately referred to as
a triune brain.
What this situation implies is that we are obliged to look at
ourselves and the world through the eyes of three quite different mentalities.
To complicate things further, there is evidence that the neural machinery
underlying the two older mentalities lacks the capacity for verbal communication.
But to say that they lack the power of speech does not belittle their
intelligence, nor does it relegate them to the realm of the unconscious.*
Stated in present-day terms, one might imagine that our brain
represents an amalgamation of three biological computers, each with
its own special intelligence, subjective sense, sense of time and space,
memory, motor, and other functions. What seems notably lacking is a
neural code for inter-signaling in verbal terms.
"... I should point out that the basic neural machinery required
for self-preservation and the preservation of the species is built into
the lower brain stem and spinal cord. This neural chassis might be compared
to the chassis of an automobile or other vehicle requiring a driver.
The odd situation that we must consider is the evolution of three different
drivers for the same vehicle, all of different minds, and all located
in the forebrain above the neural chassis.
Below are some notes I have made on some of the characteristics of
each of the three brains.
Reptilian

Now dear ones, we go below the surface "reality" of the neocortex
and into parts of our brains
which are still a great mystery to the infant "upstairs."
These intelligence centers have enabled life to survive in varied forms
for millions of years. They are not to be discounted even if they don't
speak the language of the neocortex.
Again, i will be general. the reptilian brain is the most ancient of
the brains. It has two hemispheres just like the neocortex, and it may
be that they relate functionally to the left and right hemispheres of
the neocortex.

The reptilian brain consists of the upper part of the spinal cord and
the basal ganglia, the diencephalon, and parts of the midbrain--- all
of which sits atop the spinal column like a knob in the middle of our
heads. It is thought to represent a fundamental core of the nervous
system and derives from a form of mammal-like reptile that once ranged
widely over the world but disappeared during the Triassic period having
provided the evolutionary link between dinosaurs and mammals. All modern
mammals have this reptilian complex, including humans.
First and foremost among the traits generated through the reptilian
brain is the drive to establish and defend territory. This is fueled
by an extremely potent "will-to- power," exemplified among
lizards by the ritual behavior of two rainbow lizards competing for
dominance. These animals have beautiful colors and like many lizards,
use headbobbing and pushups in assertive, aggressive, courtship and
greeting displays. In a contest, once the gauntlet is thrown down, the
aggressive displays give way to violent combat, and the struggle is
unrelenting. In victory, they are tyrannical dictators in the extreme.
In defeat, they lose their majestic colors, lapse into a kind of depression,
and die two weeks later.
At least five human behaviors originate in the reptilian brain. These
have been denoted as isopraxic, preservative, re-enactment, tropistic,
and deceptive. Without defining them, I shall simply say that in human
activities they find expression in:
--- obsessive-compulsive behavior;
---personal day-to-day rituals and superstitious acts;
---slavish conformance to old ways of doing things;
---ceremonial re-enactments;
---obeisance to precedent, as in legal, religious, cultural,
and other matters;
---responding to partial representations (coloration,
"strangeness," certain ways of moving, images of
certain kinds, etc.), whether alive or inanimate;
---and all manner of deception.
All movies and television likely are a projection of the reptilian
brain. How so? Movies and television (video games, etc.) are all undeniably
dreamlike, not only in their presentation of symbolic-reality, but also
in that humans experiencing movies, etc. have the same brain wave patterns
as when they are dreaming. And guess where dreaming originates in your
head? In the reptilian brain (although other parts of our brains are
involved).
The "language" of the reptilian brain is visual imagery. Most
communications transferred by reptiles are done so by visual symbolic
representations, each having specific meaning. Animals which have evolved
from the reptiles (mammals & birds) do dream, but reptiles do not
dream. Why? Because the reptilian mind is still operating in them and
we humans call that mental state "dreaming." There is no "dreamstate"
in reptiles because this mentality is their waking state. It is repressed
during our waking hours (but still functioning--- it never sleeps) by
chemicals released neocortically--- then the reptilian is allowed to
function during sleep and dream, when the left hemisphere is in turn
repressed. But obviously, the reptilian brain is not satisfied being
relegated to the "nightwatch" of an inert body. It wants far
more than that.
Humans invented rituals and ceremonies, and then, theater. Now where
do you suppose those revelations came from? Theater, with its famous
theorem of the "suspension of disbelief" (which is simply
another way of saying, "Put your left brain to sleep.") is
a re-invention of the reptilian mental-state "out-there".
And of course, now we have excellent duplication of the reptilian mindset
with movies and television, etc.--- which by some estimates, occupies
up to 16-18 hours of our time per day, when you add in sleep-dream time.
Ritual, ceremony, theater, movies, television, video games, etc.; all
of which was created out of the territoriality need-compulsion and the
will-to-power of the reptilian brain. This "territoriality"
and "will-to-power" is manifested in a variety of ways in
human behavior, as are other reptilian traits. Let me give some examples,
though you will soon realize that an abundance of examples is present
in our civilization.
"He" wants to marry her, and "She" might very well
be interested, but they agree that before marriage can be considered,
he must have a "good job" with a steady income and a "good
future" --- "They" are rainbow lizards (or any number
of other reptiles, birds & mammals) whose "courtship ritual"
consists of the male showing his ability to establish and protect a
certain "space" before he will be considered a suitable mate---
in short, this kind of compulsion/obssession is reptilian, no matter
how much rationale the left brain of the neocortex applies to justify
it.
As you will see, "territoriality" extends far beyond a patch
of earth in humans--- and "will-to-power" has many masks.
"Us" attack "Them" because of their skin color.
It is the color display that "Us" attack. "Us" are
cock lizards ( & countless other reptiles ). All racism is reptilian.
"B. All" is attracted to "N. Doll" because "N.
Doll" wears red lipstick. When "N. Doll" wears blue lipstick,
"B. All" is uninterested. "B. All" is attracted
to coloration--- but color is not the only physical display involved
in this compulsion. It could be any physical characteristic. "B.
All" could be addicted to warts. "N. Doll" could be mesmerized
by a certain walk.
And what about Mr. "B. All" who digs big breasts and tight
buns? Or Miss "N. Doll" who likes big dicks and biceps? They
are green anolis lizards who can only respond to some physical display---
like a flared collar or a slim chassis. B. All and N. Doll are impotent
without a hot mirage in front of their eyes. They can't get off without
hollywood or madison avenue controling their hormonal traffic; they
don't go cruising, they go vogueing. They are into drive-by orgasms.
They are turned on and off by traffic lights.
So who's doing the driving here? All compulsive reactions of either
attraction or aggression based on any physical displayal or representation
is originated in the reptilian brain.
"Goo Rue" lives in a shallow cave on the top of an isolated
mountain. "Goo Rue" follows a very simple daily routine from
which he never strays. Most of his day is spent in prayer, basking in
the radiation of his god ( which, being "beyond words," is
imaged at his altar as a serpent spiraling up a rod ). The rest of "Goo
Rue's" day is spent patiently foraging for food and "living
on the moment." Frequently, "Goo" is visited by followers
from near-by villages who prostrate themselves before him. "Goo
Rue" speaks of "timelessness & bodilessness & regeneration."
After eating, or after giving a particularly inspiring speech, "Goo
Rue" has uncontrolable sexual urges, of which only young girls
of the villages are aware. "Goo Rue" is a Komodo Dragon.
"Double-O-Dahlmer" is cool and emotionless. "Double-O-Dahlmer"
is "Goo Rue's" brother and lives on the flipside of his mountain.
"Double-O-Dahlmer" lives in isolation also, and follows a
rigid daily routine, which includes stalking and lying in wait for boys
who stray from the village. Once his prey is lured to his cave, "Double-O-Dahlmer"
feeds his needs by sexually dominating the boys and then mechanically
dismembering them. He keeps their body parts in his refrigerator. "Double-O-Dahlmer"
is a "cold-blooded killer." "Double-O-Dahlmer" is
also a Komodo Dragon.
Komodo Dragons are suspected to be the closest of living reptiles that
may resemble one of the carnivorous mammal-like reptiles that gave us
our proto-reptilian brain. Komodo Dragon hatchlings take to the trees
as soon as possible to avoid being cannibalized by adult Dragons. Remember
this, for it will take on symbolic meaning later.
All of these behaviors originate in impulses at the reptilian brain
or lower in the body, and are modified by the "higher" brains.
The reptilian brain is a powerful source of human behavior--- primarily
because it is hidden. It is deceptive. It is a secret from our conscious.
But we do "know" it emotionally, intuitively. It is the slithering
serpent in darkness! It is The Unconscious.
Zairian saying: "If you kill a snake, you're still afraid of it."
paleomammalian

A headline grabbed me this morning. it read, "Road Rage; Why This
Senseless Crime?"
Why? The answer is the paleomammalian brain.
The story told of a man driving on the highway who became enraged when
another car cut into his lane. A high-speed "race" began between
the two drivers, which ended in the death of an innocent third person.
The paleobrain uses its emotional "language" to magnify or
diffuse or otherwise redirect messages coming from the reptilian brain.
In the case above, the reptilian's sense of territoriality had been
"violated." The paleobrain emotionally magnified that message
into rage which over-rode the "conscious" influence of the
neocortex. You can see the same process going on around you (or in you)
everyday.
But a great deal more was happening than meets the eye. I will try to
be very general and brief.
Evolution created the paleobrain around the reptilian brain for two
major "reasons:"
First, to enable life to break the endless patterns of the reptilian,
so life could adapt to changes in the environment and survive. For example,
a reptilian prototype does the same thing every day of its life - the
same "day" repeated endlessly. Should an obstacle unexpectedly
appear in the reptile's normal path (like a fallen boulder), the reptile
will likely sit there unmoving until it dies. The same reptile with
a paleobrain added will use emotional energy (like rage) to overcome
the obstacle.
Second, to introduce to life the "concepts" of "parenting"
and of "play!" (in other words, the first signs of Love and
Creativity).
Unlike the neocortex and the reptilian brains, which are subdivided
in two, the paleobrain has three subdivisions; the amygdalar, the septal,
and the thalamocingulate divisions. (note that there are THREE brains
with SEVEN subdivisions - both those numbers are key in decoding symbolic
life ).

The mentation state of the paleomammalian brain is emotion.
The main thing i want to relay now about the paleobrain is this: there
is convincing evidence that the emotional energy of the paleobrain IS
AN ABSOLUTE NECESSITY for humans to have any kind of sense of bio-SELF-IDENTITY.
In other words, without emotion "I" do not exist physically.
(Poor Descartes! Without an emotional brain, his neocortex could not
have conceived, much less said, " I think therefore I am!"
The emotional energy of the paleobrain brings with it a sense of bio-self-identity.
MacLean notes that people with damaged areas of the paleobrain exhibit
a loss of self sense. Without that emotional energy, there is no physical
self-identity. ( I know, I said that 3 times )
And so oftentimes, as in the "road-rage" story above, an individual
fearing loss of "territory" also fears loss of "self."
The instantaneous response of the paleobrain is overpowering emotion.
and in that emotional release, the statement is made that "I EXIST!
and YOU cannot do that to ME!"
neocortex

Much of this you probably already know. The neocortex has been compared
to the modern computer (which it created, by the way). As i said earlier,
it is a relative "baby" and it thinks it knows everything
and that the entire universe revolves around it. It is a wonderful baby,
anyway, when it operates with Lovenergy. We all know what it can do
operating with Fearenergy.
The mentation state of the neocortex is what is called consciousness.
It functions however with two very different parts - the left and right
hemispheres. Unfortunately, historically, these two parts have been
"warring" with one another - involved in a childish tug-of-war
over "power" in the world it created around us. This "war"
is often projected as a male/female struggle - or an east/west struggle,
etc. I see much of this "warring" to be the result of unconscious
manipulation of the neo-left and neo-right by the parent brains, the
emotional paleo-brain and the territorial rept-brain.

The neocortex is "wired" to sensorally perceive the world
outside the body. Unfortunately, it seems to be less well "wired"
to what's happening inside its own body, including the valuable input
from the two more ancient brains. So often, the input from the "lower"
brains is relegated to the "unconscious" (reptilian)- or the
subconscious (paleomammalian) - which as you will see, is
disastrous.
The neo-left hemis controls the right side of the body. The neo-right
hemis controls the left side of the body. It is fairly evident that
the Left has assumed domination in the body and in civilization at the
moment. (this was not always the case - and will probably change again).
In general, the Left is seen as responsible for verbal, analytic, reductive-into-parts,
sequential-rational, time-oriented, discontinuous types of "thinking"
and behavior. The neo-left is a rational control-freak when
it is allowed to dominate.
In general, the Right is seen as responsible for non-verbal, holistic,
visuo-spatial, intuitive, timeless, diffuse types of "thinking"
and behavior. The neo-right is the shaming queen when allowed
to dominate.
Part of the reason the two hemispheres perform their specific functions
is because the Right seems to have evolved to connect with the functions
of the emotional paleomammalian brain. And the Left seems to have evolved
to connect with the functions of the highly-patterned reptilian brain
- though they are all linked somewhat to each other and can form various
"alliances" between certain parts of each brain.
I think of the neo-left as The Word ( now evolving into The Number ).
I think of the neo-right as The Way. (or The Theory)
