Violence
The term violence is a popular term that conceals more than it
reveals. All acts that cause property destruction, injury and death are called
“violence.’ The basic problem facing attempts to understand violence is that humans have a great variety
of destructive behaviors that are different. Even neuroscientists will use the
term violence indiscriminately or will suggest a simplistic classification that
has little biological basis. For example, one research group tried to relate
violence to a gene that creates the brain enzyme, monoamine oxidase. They suggested that there are two kinds of violence:
impulsive, reactive violence and predatory violence. I would suggest that there
are more kinds of violence. No single gene and no single system in the brain
will be isolated as the “cause of violence.”
Humans get angry and fight.
Angry humans are violent in different degrees with different consequences.
Fighting assumes many forms. Hitting, punching, scratching, kicking, biting are
all different behaviors used in fighting. Nice, smart people living in affluent
communities are tempted to believe that that violence is an aberration and that
humans kill because they are abnormal, sick or unduly provoked. They do not
realize that violent behaviors are innate, dominant features of human existence.
In my community,
people are relatively well behaved and killing is rare. Family violence is
common. Violent acts are not aberrations but are a constant feature of
human existence. Humans injure and kill other humans for pleasure and profit and
killing on a large scale represents the intelligent and systematic application
of knowledge, skills and discipline. The art and technology of war has been
practiced, recorded, and honored by every society that has flourished on planet
earth. In the mind of a pragmatic warlord, victory goes to the side that kills
the enemy swiftly and decisively. Hesitation is weakness and surrender is
cowardice.
Humans are Predators
Human males are natural predators who kill to eat, but also use their
predatory tendencies to kill for other reasons. Killing is a native life skill
that is carried out with skill and deliberation. With remote controlled weapons,
the most lethal acts can be launched by humans who have no experience of
violence. Weapons systems are evolving into networked extensions of human
brains. Modern warriors fight with smart weapons and unmanned aircraft that can
be remotely controlled by pilots sitting safely at workstations close to home.
Hopeful idealists imagine a nonviolent world with altruistic information
sharing. While I can imagine a nonviolent world, the reality is that this
utopian state is impossible.
Arousal, Action, Reaction System (SNS)
The autonomic nervous system is a basic regulator of social
behavior. Activating the parasympathetic system tends to pacify. Activation the
sympathetic nervous system leads to fight or flight, anger and destruction.
The SNS is a complex network arranged much like the peripheral nervous system
with segmental spinal cord roots with ganglia in the thorax and abdomen. The
adrenal gland is a peripheral resource that secretes epinephrine, norepinephrine
and steroid hormones on command from the brain, flooding the blood stream with
activation messages that reach all tissues. The SNS also commands other glands
that secrete hormones. Some of the effects of SNS activation are: pupils dilate,
sweating increases, blood flow to muscles increases, breathing and heart rate
increases, blood pressure increases, digestive activity slows or stops. You
become angry and aggressive or fearful; sometimes all SNS effects combine to
produce confusion, panic and fighting. The SNS creates strong feelings in
consciousness. You may be quietly enjoying dinner with friends until someone
insults you. Within seconds, your SNS activates flight and fight and fight" responses and you become angry. Your upset may last for hours or days and you
may never forgive the person who insulted you. The memory system gives the
highest priority to storing features of events that trigger strong SNS arousal.
Anger
Anger is the dominant human emotion. Anger is disruptive and can be dangerous. Anger is expressed by noisy displays and attacks. All human interactions are
influenced by the threat of anger and much brain power is devoted to anger
management. Anger is an old animal program that emerges from the reptilian
brain - the lizard rises up hisses and attacks. The human rises, threatens with
gestures and then, optionally, attacks. Anger energizes aggressive behavior and
is both protective and destructive at the same time. Anger has several stages
expressed at different levels of intensity. Often anger intensity escalates from
threatening behavior to all-out attack. The victor in a dispute intimidates his
opponent who either submits with conspicuous supplication behavior or is
attacked. Anger progresses to fighting.
Combatants are injured or killed in
a fight. Fights leave body scars, accounts to be settled and long-lasting
memories that facilitate future fighting. Anger is a pure and fundamental
emotion that is preprogrammed in the amygdala. Human children get angry as
infants when they are hungry or uncomfortable and do not achieve immediate
satisfaction. The term “frustration” refers to an angry outburst that arises
when seeking behaviors are blocked short of achieving the desired goal. Infants
and young children demand instant gratification of their needs and are easily
frustrated. An essential part of social maturation is learning to tolerate
delays in gratification of basic drives. Children get angry often during the day
and sometimes display alarmingly violent thoughts and behaviors. Anger is a
daily feature of sibling interaction and is common in unsupervised children's
play.
