When
early pre-humans saw their habitat change from tropical forest to
savannah, they were ill-equipped to survive. Not much fur, thin
hides, no claws or horns, and not very incisive teeth, so they
learned to run and to use body extensions. Some animals occasionally
use sticks and stones as tools, but primitive humans developed the
concept. The hand’s capacity was increased by stones shaped into
blades and points. Then the arm was lengthened by fixing these stones
to handles and shafts. Animal skins were probably used for protection
very early on, without leaving a trace. And the domestication of fire
meant cooking and keeping off nocturnal predators. Later the hand was
extended to a distance by javelins, boomerangs, tomahawks, bows and
arrows, slings and darts. Humans also harnessed animal muscle power
to carry, push and pull. With time came selective agriculture and
breeding, stone buildings, hard metals and wheels.
Humans
evolved by extending their body with artifacts. And their mind
developed with the artifice of language. Most animals and some plants
communicate with those of their own species, by smells, sounds and
movements. But the human larynx and vocal cords evolved in such a
way, possibly due to the upright position, that they can produce a
huge variety of complex sounds, more than enough to give a different
name to everything in countless different tongs. For many thousands
of years, words and the stories they built were transmitted orally.
Knowledge was memory. Oral communities live in a sound environment,
and believe that words have magical powers, for good or bad. Writing
transforms sounds into visual signs, and the alphabet does this in a
completely abstract way. Language developed human memory and made
possible the description of imaginary worlds. Writing allowed the
present to confront the past, instead of repeating it from memory,
and created an abstract personal point of view.
After
about six centuries of seclusion, Western Europe burst onto the world
stage with the first crusade in 1096. These rustic warriors
discovered the advanced and sophisticated civilisations of the Middle
East, and the Chinese inventions of fireworks and woodcut printing on
paper. Europeans would soon be printing with movable lead type and
making war with bronze cannons. Just as Europe was beginning to wake
up from its medieval slumber, the Middle East and India were ravaged
by the Mongols and subjected to Turkish overlords, and China,
possibly in reaction to the same Mongol menace, was scrapping its
navy and closing its borders. Europeans were able to conquer the
planet, because the other major powers were in such a sorry state.
The
European Renaissance revisited antiquity, and thereby questioned
religious beliefs, political institutions and scientific knowledge.
During the crusades, Europe had borrowed from afar, paper, ink and
printing, gun-powder and hard steel (Damascus), but the Middle Ages
had only invented wind-mills and sea-worthy sailing ships (as opposed
to galleys). Then, having more or less resolved their religious
oppositions by the end of the 17th century, Europeans
experienced a sudden surge in inventiveness, with celebrities such as
Newton, Galvani and Lavoisier. All this fermented into institutional
change and republican revolutions in America and France. Meanwhile
James Watt was putting together the machine that would change the
world, by the practical and rational transformation of heat into
movement.
It
is hard to imagine a world where the only motive forces were wind,
running water and muscle power, assisted by pulleys, levers and
wheels. Engines driven by steam, electricity or internal combustion
have become so ubiquitous that the only activities managing without
them are non-mechanical sports. Few people sweat at work any more.
They have to pump iron or pedal, or run on a treadmill to let off
steam. And many people never exert their muscles at all, and become
obese. Human activity has been progressively replaced by machines
that are more powerful, faster and more precise. An evolution that
began by extending and increasing the body’s capacities has finally
made them redundant.
Writing
began as an aid to memory, and books became the store of memory.
Then, during the 20th century, new ways of storing were
invented, photography and films, Bakelite and vinyl disks, magnetic
tape, laser disks and micro-chips. And the diffusion of stored
memories has also changed completely. Books, not to mention clay
tablets, are cumbersome. They need work and energy to be made and
transported. And an ever growing number of them could only be found
in libraries or by chance in a second-hand store. Films and photos
were just as hard to find and see. The internet changed all that. It
made available just about all stored memories, in print, audio and
video, to just about everyone, just about anywhere. This is producing
the same disruptive effects worldwide as did the sudden appearance of
movable-type printing in Europe five centuries ago. The mass
diffusion of ideas old and new sets off a questioning of and an
opposition to the status quo. Then as now governments tried to quell
the movement and repress the diffusion, but the jinn was out of the
bottle. There was and is no going back.
Printing
broke the top-down control of information by the Roman Church, its
universities and monasteries. The result was a religious and
political upheaval. It also introduced the mass production of an
identical object, a prelude to the industrial revolution. The new
technologies for transmitting sound and images began as highly
centralised Hertzian emissions, often under government supervision.
They diversified somewhat in the 1960s, in the wake of other liberal
movements, but, like the press and publishing, they were Big Business
and were held in very few hands. And controlling the infrastructure
gave control of the content in centre-out diffusions. The World Wide
Web has broken that duality. Mega corporations still own the
infrastructure (ITT, Orange, BT, FAMANG, etc.), but the content is
coming from billions of different sources. Mass media are being
pushed aside by social media. Pundits are losing their audiences, who
no longer want to be told what to think, and can find or form
like-minded groups on the Web. The precedent of printing breaking the
Roman Church’s cultural and ideological monopoly, and the divisions
and violence that ensued cannot be a model, though it does give an
idea of how radical that rupture is. It turns society upside-down.
Everyone can speak and be followed, not just the few who own a
megaphone.
Human
evolution has been shaped by technology. And as human societies
depend on communicating for their cohesion, their structures depend
on the forms of communication at their disposal. Oral societies
communicate by word of mouth. The messages can be modified and are
evanescent. Writing preserves the original discourses, and printing
multiplies them identically. Audio recordings preserve the actual
sound of words, instead of their symbolic representations. They no
longer have the neutrality of a visual perspective. Audio reproduces
the tone of voice and the emotions it transmits. In the 1930s and
40s, radio and sound systems played with these emotions in different
ways, from fireside chats to vituperative excesses. Video brought the
close-up, body language and subjective perceptions. Television has
used these visual projections to promote or vilipend. Audio and video
communications do not have the cool objective perspective of print.
They are hot and emotive. The voice and the face compete with the
content. Sensations and reason struggle to make sense of the message.
Words
have come back to the sensuality of sound and image, and internet has
opened their production to most of humanity. This is a combination of
two disruptive processes. A hot medium is replacing a cool one, and
information is transmitted laterally, instead of to the centre and
out again in a standard format. A sort of global mind is taking
shape, with a myriad sensors gathering and passing on information.
Language is still a barrier to complete connection, though English is
close to becoming the planet’s lingua franca. A wiki world of
cooperation is opposing the pyramidal empires of wealth and power.
Digital technology is provoking a new evolutionary leap into the
unknown, a future neither better nor worse (rapacity will probably
persist), but completely different. Having expended the body’s
physical capacities to their limits, technology has begun to push the
mind’s extensions as far as they can go. However, the body’s
sensual experience is very individual in space and time, whereas the
mind’s experience of words is built on a multitude of voices. Acts
can be copied, thoughts are shared.
Technological
extensions have increased the body’s strength, speed and dexterity,
and the mind’s memory. All activities have become artificial and
specialised, and they need a complex network of transport and
communications to be able to function. From the first stone that was
shaped and the first field that was sown, humans have evolved to a
stage where natural spontaneous phenomena no longer count. To the
point where there is talk of “terra forming” on Mars and
“engineering” the climate on Earth. Planet Gaia has produced a
species that is imagining it can change its birthplace. It is just
hubris, and the only man-made changes are the consequence of burning
all the fossil carbon that has been buried underground over hundreds
of millions of years, and covering the continents and oceans with
lead, mercury, radioactive elements and plastic particles. These
changes are all destructive, and have the potential to combine and
make future survival uncertain for most forms of life. It seems that
the power to extend the body’s physical capacities has over reached
itself. As for the mind’s extensions by print and digital storage,
there is still a long way to go. But the sheer mass of information
tends to obscure the essential elements. There are irreconcilable
opinions everywhere, especially in domains such as economics,
sociology or history that influence the way societies are governed.
What is the social cost of capitalist accumulation? Should ethnic and
cultural minorities subsist or disappear. Why spotlight some past
events rather than others? These and numerous other questions have
answers that are more ideological than reasoned. A multitude of
voices can compete with the standard discourse and point out its
contradictions. But the voices are seldom in accordance, which adds
to the confusion of fake news and downright lies. When a new medium
allows the diffusion of ideas and opinions that had previously been
silenced, the immediate result is division, chaos and reaction. But
it also gives the impulse to a different global perspective. Printing
propagated religious turmoil just as the telescope was redefining
humanity’s position in the universe. It opened an age of brutal war
and conquest, of experimental science and of political emancipation.
The World Wide Web is still in its primary stage of creative
destruction, and its ultimate consequences remain shrouded in
mystery.
