Frank
R. Wilson: The Hand:
how
its use shapes the brain, language, and human culture
(Vintage: 1998)
“When personal
desire prompts anyone to learn to do something well with
the hands, an extremely complicated process is initiated
that endows the work with a powerful emotional charge.
People are changed, significantly and irreversibly, it
seems, when movement, thought and feeling fuse during
the active, long-term pursuit of personal goals. Serious
musicians are emotional about their work not simply because
they are committed to it, nor because their work demands
the public expression of emotion. The musicians’
concern for their hands is a by-product of the intense
striving through which they turn them into the essential
physical instrument for realization of their own ideas,
or the communication of closely held feelings. The same
is true of sculptors, wood-carvers, jewellers, jugglers,
and surgeons when they are fully immersed in their work....
The word “passion” describes attachments that
are this strong. As I came to learn how such attachments
are generated, it became the mission of this book to expose
the hidden physical roots of the unique human capacity
for passionate and creative work. It is now abundantly
clear to me that these roots are more than deep, and more
than merely ancient. They reach down, and backward in
time, past the
dawn of human history to the beginning of primate life
on this planet.... Indeed, I would go further: I would
argue that any theory of human intelligence which ignores
the interdependence of hand and brain function, the historic
origins of that relationship, or the impact of that history
on developmental dynamics in modern humans, is grossly
misleading and sterile.... [Moreover,] the problem of
understanding what the hand is becomes infinitely more
complicated, and the inquiry far more difficult to contain,
if we try to account for differences in the way people
use their hands, or if we try to understand how individuals
acquire skill in the use of their hands. When we connect
the hands to real life, in other words, we confront the
open-ended and overlapping worlds of sensorimotor and
cognitive function, and the endless combinations of speed,
strength, and dexterity seen in individual human skill
and performance.”
(Wilson, pp.5-9)
There exists a deeply troubling divide within literate
humanity, at least - a divide both exacerbated by our
educational biases and deepened by the increasing complexity
of the world we have constructed. I’m speaking here
of the division which exists between people whose skills
lie in manipulation of the abstract, and those skilled
in manipulation of the concrete. Put this way, of course,
we can see how closely akin these truly are...yet everything
about our world appears to conspire to deepen this divide.
Education remains resolutely abstract - indeed, there
is increasing tendency to drop manual skill sets altogether
- whilst the world of the arts, once the natural meeting
place of craft and concept, has (at least in its “hiart”
manifestations) now downgraded craft skills to the status
of a little-regarded optional extra. As Frank R. Wilson
suggests, these are the signs of a badly skewed culture,
dismissive of a genuinely crucial side of human nature,
and paying the price for this arrogance, unknowing....
“As I located
and interviewed [people] whose careers depended on unusually
refined hand control, I found that most could spell out
in five minutes the purely procedural demands of their
work. But, to understand fully how they had incorporated
that knowledge and had turned it into a career was another
matter. Each had made a succession of discoveries that
had been followed by a strengthening of the desire to
learn more and a determination to ‘get it right’
or ‘find the truth’ no matter what the obstacles.
This process always resulted in a distinctive personalization
of their work, and a growing sense of (and demand for)
independence.... [However,] since the Industrial Revolution,
parents have expected that organized educational systems
will tame and modernize their children and ‘prepare
them for life.’ Such is the theory. But education
- ritualized, formal education, at least - is not an all-purpose
solution to the problem of inexperience and mental immaturity
among the young. [and] I was completely unprepared for
the frequency with which I heard the people whom I interviewed
either dismiss or actively denounce
the time they had spent in school. Most of my interview
subjects, although I never asked them directly, said quite
forcefully that they had clarified their own thinking
and their lives as a result of what they were doing with
their hands. Not only were most of them essentially self-taught,
but a few had engineered their personally unique repertoire
of skills and expertise in open retreat from painful experiences
in a school system that had dictated the form and content
of their education in order to prepare them for a life
modelled on conventional norms of success. Apart from
a grudging deference to what might be termed the ‘right-brain
lobby,’ what is there in our theories of education
that respects the biologic principles
governing cognitive processing in the brain and behavioral
change in the individual. How does, or should, the educational
system accommodate the fact that the hand is not merely
a metaphor, or an icon for humanness, but often the real-life
focal point - the lever or launching pad - of a successful
and genuinely fulfilling life.... [And,] once launched,
the process of self-education and development never really
stops. People are born resourceful
and they become
skilful and ‘thoughtful’ when they genuinely
care about what they are doing. One begins to understand
the origins - and learns to appreciate the interdependence
- of human skill, intelligence, and vitality by looking
at the details, one piece and one person at a time. That
is the real story I hope readers will find in these pages.”
(Wilson, pp.11-14)
As a neurologist, whose patients are predominantly the
manually-skilled w/hand injuries, Wilson is perhaps ideally
placed to comprehend such involvements. Moreover, he is
also exceptionally widely and well read - the comparison
w/Oliver Sacks comes to mind - and, again, very like that
paragon, is both a deeply sympathetic clinician and a
searcher for intellectual synthesis...in this case, attempting
to bridge the most fundamental divide within the world
of human skill. To my mind, he is startlingly successful
in this task...
“If it is true
that the hand does not merely wave from the end of the
wrist, it is equally true that the brain is not a solitary
command center, floating free in its cozy cranial cabin.
Bodily movement and brain activity are functionally interdependent,
and their synergy is so powerfully formulated that no
single science or discipline can independently explain
human skill or behavior. In fact, it is not clear that
what we have asked can be called a scientific question.
The hand is so widely represented in the brain, the hands
neurologic and biomechanical elements are so prone to
spontaneous interaction and reorganization, and the motivations
and efforts which give rise to individual use of the hand
are so deeply and widely rooted, that we must admit we
are trying to explain a basic imperative of human life.
Ultimately, this ‘meditation’ seeks to juxtapose
and integrate three quite different perspectives on the
role of the hand in human life:
1. the anthropological
and evolutionary perspective: where the human hand came
from and how it acquired the repertoire of movements that
have given it a central role in human life and survival;
2. the biomechanical
and physiological perspective: the engineer’s view
of the specialized structure and function of a forelimb
no longer used for weight-bearing and whose terminal configuration
is adapted for the control of external objects;
3. the neurobehavioral
and developmental perspective: how the dynamic interactions
of hand and brain are developed and refined, and how that
process relates to the unique character of human thought,
growth, and creativity.”
(Wilson, p.10)
And, although Wilson considers the third of these tasks
the most crucial, he certainly does not neglect the first
two. In fact, as we shall see, he tightly integrates functional
and evolutionary anthropological approaches with great
skill, and uses these to frame the stories of the manually-skilled
within the context of deep time...making clear just how
old these marvellously
varied skills are, in essence - and how foolish we are
to neglect them...
“Dancers, acrobats,
and skateboarders seem to be fully evolved biomechanically
and neurologically
as bipeds, while others have retained an aerial bias in
the hominid repertoire of automatic balancing reflexes
[and] the latter model of the biped brain lacks a full
repertoire of automatic responses in the legs
to the sudden shifting of a load above the centre of gravity.
Have you ever noticed that people who trip look like figures
in Chagall paintings...clutching for the branch that was
left behind eons
ago. The result of this outmoded reaction is almost invariably
a broken arm. What I am suggesting is that the human brain,
especially with respect to the deeply ingrained patterns
of motor control upon which survival in the trees depended
for millions of years, continues to be genetically transmitted
with a copy of a locomotor strategy more suited to movement
on a limb than on a wide, flat surface. Our distant ancestors
made no effort to carry great weights with the body; during
a fall, all four limbs could be deployed to snag a branch...[and,]
in fact, falling was a normal mode of locomotion .”
(Wilson, pp.77-8)
“Because of the
body’s virtually limitless freedom to employ convenient
combinations of muscle activity to achieve a desired movement...a
specific solution to the problem comes about only because
the central nervous system has the capacity to call upon
skeletal muscles the way a commanding general calls on
his troops, combining the available forces to meet certain
tactical objectives as they arise, and continually recombining
them into ad hoc working groups based on his perceptions
of what each can do and what each mission will require....
This flexibility may seem to be an ideal arrangement,
but (just as with a real army) it comes at a very high
price...a nightmarish challenge for the nervous system.”
(Wilson, p.89)
“Brachiation may
have begun simply as a biomechanical accommodation to
increasing size and weight, or to the advantages of suspended
feeding...but the resulting increased mobility in the
upper arm effectively permitted the animal to locate either
hand virtually anywhere...[and] the brain must have responded
to this purely biomechanical change by increasing the
complexity of its representation of the hand and arm in
space.... In sum, we must infer that brachiation placed
an enormous burden on the brain’s kinesthetic monitoring
and spacial computing power, since there were so many
new places the hands could actually be while they were
doing their job. Eventually, there must also have been
countless new tasks for the arms and hands that required
differentiated use of the right and left hands, as well
as the capacity for refined coordination of the two hands
during bimanual tasks.”
(Wilson, p.29)
The evolutionary story Wilson tells is, in part, a familiar
one - yet it is much, much richer than those offered by
palaeoanthropologists in this area, and filled with details
that help make real sense of what little we know about
hominid evolution. Just as Kingdon’s Lowly
Origin used functional anatomy, biogeography and
ecology to challenge and recast our understanding of our
upright status, so too Wilson’s specialist knowledge
proves essential to comprehending the hand in human evolution.
Combined with Merlin Donald’s Origins
of the Modern Mind, these books offer us our very
best guides to the sheer complexity
of the factors involved in human evolution, presenting
a badly-needed corrective to the just-so savannah stories
we are used to. Moreover, Wilson - as I said - is an exceptional
synthesist, and makes the work of both Merlin Donald and
Henry Plotkin central to his evolutionary story...building
upon their innovations and fleshing out their models with
the insights which come from his specialist knowledge.
The result is a crucial part of our story:
“When the australopithecines
started walking upright, the upper limb had not changed
much, and it is unlikely that the control mechanisms were
different, either. Had there been any major changes, you
might suspect that the arm was destined to be downgraded
- either to a structure with a merely ornamental function,
or to a shrunken version, possibly like the forelimbs
of the kangaroo.... But the hominid arm did not wither,
either anatomically or functionally. Why? One possible
answer is that the brachiating arm (unlike the forelimb
of mammals lacking its unique experience and capabilities)
had already secured a major ‘presence’
for itself in the brain - that is, its complex functions
had come to be widely represented and ‘networked’
into expanded sensorimotor systems within the central
nervous system.”
(Wilson, p.62)
“Mary Marzke,
a physical anthropologist at Arizona State University,
has spent a great deal of time looking at the hand and
wrist bones of Australopithecus afarensis .
Professor Marzke points out that although Lucy does have
an opposable thumb, other primates also have this feature.
Chimps and monkeys, in fact, are quite good at bringing
the thumb to the side of the index finger. What they don’t
do well (as Lucy herself could not do) is bring the thumb
tip all the way across the hand to the fourth and fifth
fingers. Also, neither the apes nor Lucy flex the fingers
on the ulnar side of the hand (the side with the little
finger) toward the base of the thumb, in the movement
known as ‘ulnar opposition.’ We humans do
this without the slightest sense of marvel whenever we
grasp the handle of a hammer, a golf club, or a tennis
racket and prepare to take a swing. The advantages in
Lucy’s hand are nearly impossible to appreciate
without studying her wrist bones...[but] taken together,
these changes move the radial
(or thumb) side of Lucy’s hand dramatically toward
the twentieth century. The apparent functional advantages
of the changes are:
* the thumb, index and
middle fingers can form a ‘three-jawed chuck,’
which means the hand can conform to, grasp, and firmly
retain irregular solid shapes (such as stones);
* finer control can
be exerted over objects held between the thumb and the
tips of the index and middle fingers;
* rocks can be held
within the hand to pound repeatedly on other hard objects
(nuts, for example), or to dig for roots, because the
new wrist structure is able to absorb (dissipate) the
shock of repeated hard strikes more effectively than the
ape hand....
[As well,] she could
have thrown overarm because her shoulder had the capacity
for full brachiation (including forearm supination), her
hand was capable of a ‘three-jawed chuck’
grip, and her pelvis and its musculature permitted a whipsaw
movement of the full axis of the body during the windup
and throwing motion.”
(Wilson, pp.24-7)
“The accelerated
development of the hand (and of the brain supporting its
new repertoire of movements) in Homo
seems not so much a de novo
invention as the completion of what had already been worked
out in the rest of the arm (and the shoulder) prior to
our arrival on the ground.... If the australopithecine
hand ventured out...less than fully prepared for the challenges
it would meet, the shoulder and arm and their neurologic
support systems were very likely already well ahead
of the game ...[albeit]
there were other changes that had to be made to capitalize
fully on this ballistic potential, most prominently an
advanced visual-motor control system. And catch up is
exactly what the hand (and brain) did. Very quickly -
on an evolutionary time scale, that is - the hand and
brain not only met but began to redefine the demands and
possibilities of a life in which forelimbs had been freed
of the obligation to support body weight.”
(Wilson, pp.78-9)
“It is actually
quite easy to see that the establishment of a lateralized
habitual upper-limb skill could have conferred a critical
survival advantage on the australopithecines...and that
it must have
occurred if marksmanship was their basic weapon.... For
most, if not all, primates, voluntary sequential movements
of the limbs, no matter how complex, are executed with
increasing fluency and precision the more they are repeated....
[Moreover,] the control of [such] an invariant sequence
of interacting muscle contractions requires nothing less
than perfect regulation of the start and stop times of
all these events, which in turn determine the movement
of each of the involved limb segments, and which regulate
even their contractile state through the course of the
movement and at its endpoint.... Apparently ,
regulating the timing of all the necessary ‘on’
and ‘off’ switching is a large part of what
is so difficult in perfecting movements that are rapid,
brief, and (of necessity) extremely accurate. Perhaps ,
the control problem is further complicated by the need
to segregate commands sent to proximal limb segments from
potentially incongruous or conflicting commands simultaneously
directed to distal segments. Small wonder the move demands
practice.”
(Wilson, pp.152-5)
Once we take the trouble to add the functional anatomy
to the story, we can see much more clearly just how the
shoulder - and then the hand - effectively led
the brain into new evolutionary territory, with varieties
of throwing (as William Calvin has argued) almost certainly
providing the leading advantage. And so, by the time real
brain expansion occurred w/ ergaster
and erectus,
there were cogent survival reasons driving it, as well
as the likely forces of sexual, social, and cultural selection
making multiple uses of all that new neocortex. But manual
demands led the way...
“Throwing may
well have become more of an attack skill in Lucy than
it ever could be in chimps, but a major improvement in
clubbing had to await changes in the ulnar side of the
wrist and hand, which came after the time of A.
afarensis . The trick
of ulnar opposition...permits a stick to be seated tightly
in the hand, and oriented along the axis of the arm, so
that the swinging radius of arm-plus-stick (and, therefore,
the force of a blow) increases.... A second effect of
ulnar opposition can be seen in an improved precision
grip...[only now involving] all five digits in the fine
control of small objects. This one ‘small’
modification, in other words, would have greatly enlarged
the functional potential of the hand at both ends of the
existing behavioral repertoire, opening the possibility
for both a more combative and a more digitally dextrous
individual.”
(Wilson, pp.27-8)
“Structure and
function are interdependent and co-evolutionary. The brain
keeps giving the hand new things to do, and new ways of
doing what it already knows how to do. In turn, the hand
affords the brain new ways of approaching old tasks, and
the possibility of undertaking and mastering new tasks.
That means the brain, for its part, can acquire new ways
of representing and defining the world.”
(Wilson, p.146)
“It is likely
that sometime during its stewardship of the genetic lineage
of Homo , erectus
completed the final revisions to evolution’s remodelling
of the hand, opening the door to an enormously augmented
range of movements, and the possibility of an unprecedented
extension of manual activities. As a collateral event,
the brain was laying the foundations of cognitive and
communicative capacity. I would not suggest that a tiny
modification of this ancient pentadactyl structure by
itself closed, or even catalyzed the closure of the narrowing
gap between Merlin Donald’s mimetic culture and
its successor, the mythic
culture. Rather, this new hand reflected a modification
of the primary heuristic, and brought with it the opportunity
for a new class of situational knowledge based on as yet
unexplored and undefined use of the hand.... Absent what
preceded it, surrounded it, and was still to come, it
would have been neither burr nor spur. But, with the advantage
of hindsight, we can guess that events following this
anatomic change conspired to produce a second iteration
of Plotkin’s secondary heuristic: ‘manual
intelligence,’ just plain ‘hand smarts.’...
[For] the handyman’s hand was more than just an
explorer and discoverer of things in the objective world;
it was a divider, a joiner, an enumerator, a dissector,
and an assembler.... [And] there is growing evidence that
H. sapiens acquired
in its new hand not simply the mechanical
capacity for refined manipulative and tool-making skills
but, as time passed, an impetus to the redesign, or reallocation,
of the brain’s circuitry.... A new physics would
eventually have to come into this brain, a new way of
registering and representing the behavior of objects moving
and changing under the control of the hand. It is precisely
such a representational system - a syntax of cause and
effect, of stories and experiments, each having a beginning,
a middle, and an end - that one finds at the deepest levels
of the organization of human language.”
(Wilson, pp.58-60)
And, as might be expected of a writer with his rare breadth
of concern, Wilson has quite a bit to contribute to our
understanding of language, and its evolution, albeit his
proposals fit comfortably within the approach most associated
with Merlin Donald and Stephen Mithen. Still, he has his
own (manually-creative) take upon this area, and his arguments
are both unusual, and important...
“Praxis
refers to a heterogeneous class of movements in humans
that, by virtue of motivated planning and rehearsal ,
exploit novel biomechanical (structural) modifications
in the human hand, in order to gain precise and extended
control of external objects. Because of their intentionality
and the precision (or stereotypy) that arises through
rehearsal, these movements become iconic. The praxic
movement, in other words, is perforce a sign for the act
which it accomplishes, irrespective of the communicative
intent of the doer ....
It has long been agreed that there are two qualitatively
different forms of skilled, representational movement,
best exemplified by the differences between gesture and
sign. But no one has ever suggested that there might be
a whole other class of representational movements - those
imbedded in highly practised movements which are meaningful ,
but neither gestures nor signs ....
Musical skill provides the clearest example and the cleanest
proof of the existence of a whole class of self-defined,
personally distinctive motor skills with an extended training
and experience base, strong ties to the individual’s
emotional and cognitive development, strong communicative
intent, and very high performance standards.... [But]
to the cognitive scientist and the neurologist alike,
the highly trained, creative hand remains almost entirely
unseen, and unrepresented in the thinking of clinical
and theoretical neurology.... What do we imagine actually
happens in the brain during a painter’s lengthy
apprenticeship, and during her subsequent period of development?
Why do we fail to see that any advanced physical skill
has its own internal ‘logic’ with specific
minimal operational characteristics (limited input sources
and output channels, a limited range and type of timing
operations and calculating operations), and the freedom
to be modified over time based upon experience? Language
and music fit, but are not the only examples.”
(Wilson, pp.204-8)
“We lose ourselves
in the details. We find the right and left hemispheres
respond to certain challenges in distinctive ways - one
does a job faster than the other, or better, or more reliably
- and we conclude that this hemisphere is specialized
for that function. It is important and useful (maybe)
that we make these discoveries, but they are true only
as artifacts of the tests we devise. Once the left hemisphere
and the right hemisphere join forces, our attention, or
perspective, must shift to take account of that unique
combination and a new set of consequences. Language is
not just words, semantics, syntax. It is also melody,
and sometimes, it is dance. Sometimes, as in the deaf,
it is a silent dance of the hands. It is a voice, a face,
and the words between the lines.... [For] the strength
of a biological system cannot be judged independent of
context.”
(Wilson, p.307)
To this point, I have concentrated on the evolutionary
story, sketching out Wilson’s arguments in this
area, which are both complex and extremely well-supported.
But this is only one of the many strengths of this remarkable
book, and probably not the one most of its readers would
first think of. That award would go to the remarkable
stories of the manually-skilled - the puppeteer, the juggler,
the rock-climber, the chef, the jeweller, the mechanic,
the magician/surgeon, the musician, and the deaf signer
- which both frame and illustrate the evolutionary/functional
arguments with a rare degree of insight...
“Almost all physical
skill flows from the maturation of motor skills under
the guidance of both visual and kinesthetic monitoring...[and]
both the hand and eye develop as sense organs through
practice, which means that the brain teaches itself
to synthesize visual and tactile perceptions by making
the hand and eye work together.... The brain actively
orients the the receptors in the eye or the hand toward
a target of interest, and then moves them precisely during
a process of exploration. [Moreover,] the resulting image
constructed by the brain must, of necessity, be based
both on the messages from retinal and/or skin receptors,
and on the record of guided eye or limb movements occurring
during the collection of the sensory data.... One extremely
important difference between the eyes and the upper limbs
as movable explorers has to do with the biomechanical
(hence ‘computational’) complexity of moving
the sensor (retina or fingertip) to the target of interest.
The eye, assuming the head to be in a favorable position,
need only rotate toward the target to bring light from
it to the retina. The hand, however, is located at the
end of a complex biomechanical linkage and must actually
get to the target to be touched [while] the body may first
have to be moved toward the target. Once there...the reaching
arm has wide latitude in the combination of joint angles
and contraction-relaxation patterns.”
(Wilson, pp.97-8)
“The right hand
is the tool holder, and the left hand is the manipulator.
You have to hold the tool exactly so that it does the
same thing every time. You rotate the work to the place
where it should be.... Learning how to control the tools
used in jewelry-making can take as little as two or three
months. And it takes in quite a few senses. It takes in
the sense of hearing, as well as the physical sense of
how a tool is touching something else. For example, with
a torch you are concentrating on heating something without
melting it, so you’re visually focused tightly on
what’s going on there. But you are also sensing
the sound the torch is making. You can hear a change in
the mixture of oxygen and gas, depending on where the
torch is. Of course, vision plays a very big part, but
there is also the physical feeling when the tool you’re
holding is in the proper position and is making the proper
contact. When you’re filing or hammering, there’s
also the sound. Hammering on a piece of metal is like
ringing a bell. A person needs to have feeling for all
of these things. You know, tools are very sensual things,
and using them can be. The filing, the polishing, drawing
is very physical, sensual. Filing is almost like petting
a cat.”
(George McLean, quoted
in Wilson, p.142)
“An extremely
important dissent from the inferior-superior and ‘just
different’ theories [of handedness] was published
in 1987 by French psychologist Yves Guiard...[in which
he argued] the question should not be which hand is dominant,
but how the two hands interact, or complement each other’s
actions in a given task.... In writing - as consistent
a unilateral task as is known - Guiard showed that the
nondominant hand plays a complementary, though largely
covert, role by continuously repositioning the paper in
anticipation of pen movement.... Looking beneath complementarity
as a principle, Guiard went on to show that the physical
characteristics of movement, and the requisite sensory
control mechanisms supporting each, were different. Specifically,
movements of the dominant hand tended to be lower in excursion
(amplitude) and faster in repetition rates...[while] the
nondominant hand...‘frames’ the movement of
the dominant hand: it sets and confines the spacial context
in which the ‘skilled’ movement will take
place.... Finally, said Guiard, the framing, stabilizing
activity begins in one hand before the action of the other
member of the pair. In summary...the left hand
knows what the right hand is planning, and the right hand
knows what the left hand just did ....
[Moreover,] the dominant hand’s performance is micrometric,
rehearsed, and for the most part internally
driven (‘pre-programmed) [whereas] the performance
of the nondominant hand is macrometric, improvisational,
and externally
driven.”
(Wilson, pp.159-62)
And the virtues of this remarkable book certainly don’t
stop there. I have yet to mention the compelling theory
of heterotechnic groupings (everything from makers of
stone tools to teenage car enthusiasts), his resolutely
unfashionable coupling of work and pleasure (yet another
neglect within our dominant culture), or the insightful
arguments re object and language handling parallels which
nicely complement and extend the interpersonal approach
of developmental psychologists such as Hobson, and the
educational theories of Kieran Egan. As such, it highlights
a general strength of the work I have so far neglected.
That is, throughout the text - amidst all its other concerns
- Wilson never loses sight of the other
dimension of the historical, that is...the developmental:
“The long march
toward physical and mental agility begins when the infant
is still on its back, where it must remain until the muscles
of the neck can hold the neck still while the eyes search
and study...[leading] to perceptual stabilization of the
visual world. [Moreover,] the coupling of hand and eye
movement is an enormously complicated learning task in
which the child must be intensively engaged before it
can ever hope to pry its bottom off the floor.... [Furthermore,]
before the fingers begin to work independently, two critical
and apparently separate events in neuromuscular development
are necessary: the arm must have learned to move to a
target under the guidance of the eye, and the hand must
have learned to orient and shape itself in preparation
for grasping the target. The first of these stages is
normally complete before the age of five months, and the
second before the age of ten months; after that, the hand
is ready for a lifetime of exploration.”
(Wilson, pp.98-9)
“Very gradually,
as work progressed on this book, I came to realize that
an unexpected dialogue was developing between two sets
of information I had been considering.... The dialogue
was an exchange between the experiences of individual
learners, and certain large-scale constructs of cognitive
and behavioral science. Serge Percelly’s description
of the pragmatics of juggling, worked out almost entirely
on his own, ‘speaks to’ the findings of a
research group in motor control and computer science at
MIT. George McLean’s insights about bimanual control
of tools, gained from his remarkable experience following
the loss of four fingers of his dominant hand, echo a
research laboratory’s hard-won discoveries concerning
hemispheric specialisations for dominant-nondominant hand
control. [And] Dorothy Taubman and Patrick O’Brien
deduce important
principles of action of the small muscles of the hand,
and challenge neurologists who consider musician’s
(and writer’s) cramp to be a consequence of brain
disease.... Obviously, there can and should be a bidirectional
character to this ‘dialogue between sets’
I have been describing. But it is in fact remarkably difficult
to find examples of reinforcement of the small-scale particularities
of individual learning from the larger world of science.
That is, it does not seem that we have yet learned
how to apply systematically to individuals what we know
from biology about the nature of human learning .”
(Wilson, pp.286-7)
“There will continue
to be individuals whose accomplishments will astonish
the experts, by proving to be useful or even critically
important, despite all predictions to the contrary. We
can neither fully anticipate our future needs (what we
will regard as talent or genius), nor fully orchestrate
a survival strategy for ourselves. We can, will, and should
do both of these to the best of our abilities, but we
will never beat evolution at the game that created us.
Therefore, we must make provision for those amongst us
who hear a different beat, and are compelled to march
to it.... [Moreover,] although we are different, we almost
certainly benefit by capitalizing on our differences.
The knowledge to do this, if it exists, must exist collectively,
as a distributed, heritable trait outside the individual,
but within the community itself.... Might we detect this
community trait
by gene testing? I doubt it. Can we duplicate its effectiveness
by aptitude testing, educational policy, and social engineering,
or stuffing our children with vitamins, surrounding them
with interactive toys, and badgering them about getting
into Ivy League colleges? What do you
think? ...Understanding or reengineering the brain will
not save us; neither will sitting our children in front
of computers when they are three years old, so that they
can skip the ‘pointless’ experiences of childhood,
during which they find out what a baseball, or a puppet,
or a toy car, or a swing can do to their body, and vice
versa.... The fully computerized kid may turn out to be
just like us, or strikingly different, as a consequence
of having replaced haptics with vision as the primary
arbiter of reality, and having substituted virtual baseball
for the old-fashioned kind at an age when the brain’s
sensorimotor system hasn’t settled on the time constraints
it will use for its own perceptual-motor operations....
I am not surprised that we are so eager as a society to
welcome the Internet into our public schools. I am
a little surprised that we are so ready to say goodbye
to the playground and the books in the school library.”

Frank R. Wilson’s The
Hand is a truly marvellous book, juggling evolutionary,
technical and experiential perspectives from a variety
of practitioners to provide us with that very rare thing
- a comprehensive understanding of just how, and why,
our hands are so important to us... By marshalling such
a startling variety of perspectives, as well, Wilson’s
work provides a standing reproach to most scholarship,
bound (as it is) more by disciplinary niceties than by
the real demands of its subject matter...let alone the
real needs and wants of any potentially wider readership.
By reuniting hand and mind - not to mention brain and
body - in such a comprehensive fashion, Wilson has performed
a critically-important task, which is even more needed
today than it was in the past. Any evolutionary and/or
developmental account which neglects this question - as
too many sadly do - is, as Wilson convincingly argues,
profoundly inadequate.
But the relevance of this work does not stop there...
For there is also our narrow-minded & politicized
educational approach to be considered, not to mention
our understandings of work, play, and, in fact, the shape
of human life itself. Wilson addresses all of these in
this remarkable book, which is undoubtedly one of the
most important of our times.
“We begin life
with our parents as the first teachers, learning through
early exposure to toys, language, music, and other children
and adults. We perceive change in ourselves through countless
interactions, formal and informal, with others to whom
we are drawn or driven: teachers, relatives, friends,
and rivals. As emerging adults reaching toward the heady
goal of independence, we seek to match ourselves to an
exemplary archetype, and through emulation of this person
(his or her principles and work) we are directed toward
a life of productive work, companionship, and reward.
The socialization that formal education strives so hard
to inculcate is, as Kieran Egan argues, actually built
into this process as we increase our familiarity and facility
with tools (hand-held and cognitive) offered to us....
No wonder learning is so hard to control, so easy both
to direct and to misdirect. It is brain and hand and eye
and ear and skin and heart; it is self alone and self-in-community,
it is general and specific, large and small. The interaction
of brain and hand, and the growth of their collaborative
relationship throughout a life of successive relationships
with all manner of other selves - musical, building, playing,
hiking, cooking, juggling, riding, artistic selves - not
only signifies but proves
that what we call learning is a quintessential mystery
of human life. It demands energy, but produces more than
it consumes.... It marks the fusion of what is physical,
cognitive, emotional, and spiritual in us...[and] is reshaped
continuously as hand and brain vitalize one another, and
the capacity to learn grows continuously as we fashion
our own personal laboratory for making things.... It may
be that a greater appreciation by parents and teachers
of these facts would bring formal learning and self-directed
‘life learning’ into a more mutually reinforcing
relationship. It may also be that the most powerful tactic
available to any parent or teacher who hopes to awaken
the curiosity of a child, and who seeks to join the child
who is ready to learn, is simply to head for the hands.”
(Wilson, pp.294-6)
