Phrenology
By Renato M.E. Sabbatini, PhD
Today, even the least informed high school student knows
that many functions of the brain are carried out by
particular structures, and not by others. For example, the
external part of the brain, called cortex, has regions
which are responsible for different functions, such as the
perception of vision and hearing, the control of movement
and speech, as well as the higher mental faculties
(cognition, planning, reasoning, etc.). This doctrine,
which has been proved over and over again in this era where
sophisticated equipments, supported by computers, are able
to visualize with pinpoint precision where a given function
is being performed in the brain, is called cerebral
localizationism.
But this was not so in the final years of the eighteen
century, the century of Illumination. Knowledge about the
brain was scanty and dominated by non-scientific
speculations. Objective experimentation with animals was
still rare, and one the most powerful methods of inferring
brain function, the observation of persons with
neurological disabilities due to localized lesions of the
brain, such as tumors, was still in its beginning stages.
The main source of knowledge about the brain were the
dissections performed on the dead bodies of animals and
humans. Localization of function in the brain could only be
glimpsed from the fact that there are many
different-looking anatomical structures in it, so that,
perhaps, they could be responsible for different faculties
of the mind.
In this bleak scenario, enters the Austrian physician Franz
Joseph Gall (1758-1828), who pioneered the notion that
different mental functions are indeed located in different
parts of the brain. This happened exactly 200 years ago, in
1796 ! As we will see, he was right on this notion, but totally
wrong on the way it was achieved by the brain. As a
result, he produced phrenology (from phrenos=mind,
and logos=study) the first complete theory of
cerebral localizationism This was surely a major feat.
However, phrenology was later discarded and castigated by
the scientific establishment as a crude form of quackery
and pseudoscience. But his historical importance
remains, so's the reason for the present article.
The
Theory Behind Phrenology
Gall, in his noted work, "The Anatomy and
Physiology of the Nervous System in General, and of the
Brain in Particular", put forward the principles
on which he based his doctrine of phrenology,.
Firstly, he believed that man's moral and intellectual
faculties are innate and that their manifestation depends
on the organization of the brain, which he considered to be
the organ responsible for all the propensities, sentiments
and faculties.
Secondly,
Gall proposed that the brain is composed of many particular
"organs",
each one of them related or responsible for a given mental
faculty. He proposed also that the relative development of
mental faculties in an individual would lead to a growth or
larger development in the sub-organs responsible for them.
Finally, Gall proposed that the external form of the
cranium reflects the internal form of the brain, and that
the relative development of its organs caused changes of
form in the skull, which could be used to diagnose the
particular mental faculties of a given individual, by doing
a proper analysis.
In fact, Gall's theory was built the other way round. He
carried out numerous and careful observations and made many
experimental measurements on the skulls of his relatives,
friends and pupils. Later on, with the help of his
associates, he did that on many persons with different
personality characteristics. Gall thought that he was able
to correlate certain particular mental faculties to bumps
and depressions on the surface of the skull, its exterior
forms or relative dimensions. Then, he mooted on the
possibility that these external landmarks could be caused
by the growth of internal brain structures, and that this
growth was related to the development of the associated
mental faculty. Thus, he was able to produce a complete and
extensive theory to support his work, and to use it for
practical applications in the mental sciences, by means of
detailed topological
maps. The most important collaborator of Gall was
Johann Spurzheim (1776-1832), who later helped him to
extend the so-called phrenological model and to disseminate
it in Europe and USA.
Phrenology's
Destiny
The logical and easy-to-learn structure of the
phrenological theory quickly captured the imagination of
thousands of followers. The preciseness and scientific
assurance of its terms and maps made headway in a time
where the main enemies of rationalism were religion,
subjectivity and autocracy. Due to this, Gall gained the
support, if not the minds, of many important scientific and
political figures in many parts of the world. He was their
champion, in a terrain dominated by the teachings of
religious philosophers.
Eventually, phrenology was attacked by the scientific
establishment, which could not corroborate Gall's theory
with concrete findings. Already in 1808, the Institute of
France assembled a committee of savants. led by Cuvier, who
declared that phrenology was not to be trusted (some
historians suspect that they also had no scientific
evidence to support this claim, and that the conclusion was
forced by Napoleon Bonaparte, who was furious because
Gall's interpretation of his skull "missed" some
noble qualities he thought he had...)
Phrenology was equated to other forms of quackery,
mainly due to the abuses in the hands of shady commercial
entrepreneurs. Its demise happened in the final quarter of
the nineteen century. However, it spawned many other
scientific or pseudoscientific branches based on the
quantitative analysis of facial and cranial features, such
as craniology, anthropometry and psychognomy, many of which
survived well into modern
eras. Amazingly enough, there are still followers and
believers of phrenology around.

Franz
Mesmer & Hypnosis
What is the derivation of the word
"mesmerize" and what does it have to do with Ben
Franklin?
In the early 1770s, Franz Friedrich Anton Mesmer, an
Austrian physician and theologian, developed a technique
that he claimed could cure a variety of physical and mental
ailments. His theory, called "animal magnetism,"
was based upon the idea that there existed "magnetic
fluids" in nature, which could be used to rid the body
and mind of many diseases. While in Vienna, he purported to
have "cured" a young pianist of hysterical
blindness through his magnetic therapies.
After having worn out his welcome in Vienna, Mesmer
traveled to Paris in 1781, where he became very popular
among the upper classes and members of the French court.
Mesmer held special salons with dim lighting and soft
music. Mesmer would move around the room and use his hands
to channel invisible magnetic fluids to his followers. The
combination of light, music, and incantations from Mesmer
produced a form of hypnotism or "mesmerism."
Many
influential people flocked to Mesmer to be cured of all
kinds of problems, real and imagined. Wolfgang Amadeus
Mozart was a follower of Mesmer, as was the French queen
Marie Antoinette. Mozart performed a musical play in
Mesmer's honor, and Mesmer frequently was invited to the
French court to perform for the queen. Because of his
popularity at court, Mesmer became quite a celebrity in
France and attracted a great deal of attention.
King Louis XVI, who was not as taken with Mesmer as his
wife and other members of his court, commissioned the
French Academy of Sciences to investigate Mesmer and his
therapeutic claims. The academy appointed a number of
prominent scientists and citizens to the investigating
committee. Among the members were scientists Antoine
Lavoisier, Paris mayor Jean Bailly, Dr. Joseph Guillotin,
and, of course, Benjamin Franklin. Ironically, both
Lavoisier and Bailly met their deaths on the beheading
device named after Dr. Guillotin.
Because of Franklin's poor health, the committee conducted
their tests and investigations at Franklin's residence in
Passy. Mesmer attempted to distance himself from the
proceedings by sending an associate, Dr. Charles Deslon, in
his place. It was a clever ploy because if Deslon
succeeded, Mesmer could take the credit; if Deslon failed,
Mesmer could blame his assistant.
Deslon set about demonstrating how animal magnetism worked.
One of the most dramatic tests involved
"magnetizing" a tree and then having a subject
identify the tree that had the most magnetic force. Deslon
prepared one of the trees, then blindfolded the subject, a
twelve-year-old boy, and directed him to embrace several
trees in Franklin's garden. The boy reported various
sensations and said that the magnetic force was getting
stronger, even though he was moving farther from the tree
that Deslon had magnetized. The experiment ended when the
boy fainted.
The commission's public report concluded that there was no
scientific evidence of animal magnetism and that the cures
attributed to it may have either happened through a normal
remission of the problem or that the cure was some form of
self-delusion.
Mesmer's attempts to avoid the commission's work failed,
and he quickly lost popularity. He left France and died
years later in Switzerland. Although Franklin and his
colleagues debunked many of Mesmer's practices and
theories, Mesmerism continued to be practiced for another
century or so and had a resurgence in England during the
late Victorian period.
Whether he was a charlatan, a showman, or a true believer
in his own practices, Franz Mesmer is credited as being one
of the fathers of modern day hypnosis and psychotherapy.

In the 1700s, Franz Anton Mesmer was born, marking a
turning point in the history of mind control. Mesmer developed
a technique called "animal magnetism" as a medical
technique for treating a number of illnesses (primarily
psychosomatic) which were not well understood at the time.
Animal magnetism was quickly dubbed "mesmerism" and
later morphed into "hypnotism."
Mesmerism involved different techniques, including the
placement or brandishment of literal magnets around the
subjects, and the monotonous repetition of words and tones,
which induced a trance-like state in its subjects.
In
a hypnotic trance, the subject is prone to suggestibility.
They tend to believe what they are told and their senses will
malfunction to back up these suggestions. Mesmer primarily
used the technique to cure various stress-related illnesses
but it soon became clear that hypnotism could also be used to
make people do things they wouldn't normally do.
Today, any respectable hypnotist will assure you that a
person under hypnosis can't be induced to do anything they
wouldn't normally be able to do. But then, it's not the
respectable hypnotists that you have to worry about.
Regardless of their protestations of harmlessness, the
suggestibility of a hypnotized subject offers ample
opportunity for the hypnotist to wreak havoc.
Aside from the possibility of just ordering the subject to
become a killing machine, which is not a reliable technique,
one can plant suggestions that allow the subject to justify
all manner of wrongdoing (i.e., "Jim is planning to kill
you. He will kill you unless you kill him first. You had
better kill him in self-defense.").
Hypnotic techniques can also be used to plant
"post-hypnotic" suggestions, in which a certain set
of circumstances (such as the utterance of a "trigger
phrase") cause the subject to act out a preprogrammed
behavior. This is more popular as a Hollywood device than
effective in the real world, but it can be done.
The main problem with hypnosis as a mind-control technique
is that it's pretty difficult to hypnotize someone against
their will. That's why insidious megalomaniacs returned to the
techniques used by the first Assassins — drugs — while
inventing new and exciting ways to manipulate the masses in an
economical fashion.
