Norbert Wiener's Animal/Machine
When approaching such metaphorical
connections as computers to minds, another member of the scientific community
comes to light. Norbert Wiener's cybernetics, conceived around the same
time as von Neumann's Monte Carlo simulation, contributed to the conceivability
of humans as machines. Here again, the War and the roots of the Cold War
are seen as expressions of the same epistemological movement.
In 1943, von Neumann and Norbert
Wiener, along with Gregory Bateson, Margaret Mead, Walter Pitts, and others,
met over several months in Boston to establish a new interdisciplinary
study concerning the role of information in systems. In these Macy meetings
(named for their sponsor), Wiener dubbed the new science cybernetics,
whose root carries with it the intention of the science. The Greek, kybernotos,
means "pilot" or "steersman," and the Latin equivalent refers to governance.
Cybernetics, then, was a science devoted to describing the controller in
all systems of information, including the mind that steers human behavior
and communication. That behavior could include everything from the regulation
of a heart beat to the governance of foreign policy.
In 1948 Wiener published a book
for the general public on the feasibility and philosophy of machines that
learn. The book, Cybernetics, or Control and Communication in the Animal
and the Machine, went through four printings in the United States in
its first six months, selling 21,000 copies during its first decade. As
Wiener's ideas were embodied in computer models and developed by other
theorists, cybernetics gradually achieved a quality of governance (This
is especially true when computer simulations, taken as intelligent machines,
are used in an advising or even executive role in policy making decisions.)
As a result of Wiener's work, the notion of feedback penetrated almost
every aspect of technical culture. Though the central concept was both
old and commonplace in specialized circumstances, Wiener gave the idea
strength by generalizing the effect into a universal principle. Lifelike
self-control became a simple engineering job. The general engineering problem
became: If all the variables are tightly coupled, and if you can truly
manipulate one of them in all its freedom, then you can indirectly control
all other variables. This principle plays on the holistic and unified nature
of systems.
In a later description of cybernetics,
Wiener made it clear that he was von Neumann's collaborator. He, too, was
repelled by uncertainty. In The Human Use of Human Beings he wrote:
The scientist is always working
to discover the order and organization, and is thus playing a game against
the arch-enemy, disorganization. Is this devil Manichaean or Augustinian?
Is it a contrary force opposed to order or is it the very absence of order
itself? . . . The Manichaean devil is playing a game of poker against us
and will resort readily to bluffing; which as von Neumann explains in his
Theory of Games, is intended not merely to enable us to win on a
bluff, but to prevent the other side from winning on the basis of a certainty
that we will not bluff.
Compared to this Manichaean being
of refined malice, the Augustinian devil is stupid. He plays a difficult
game, but he may be defeated by our intelligence as thoroughly as by a
sprinkle of holy water . . . (pp. 49-50). After this spurious foundation is
established, everything in cybernetics logically follows. The notion of
the binary unit, or bit (elsewhere proposed by both von Neumann and Turing),
was enormously refined and given a larger context under the influence of
Wiener's definition. The crucial notions of positive and negative feedback
— especially as applied to organic and mechanical systems — now could be
rationalized by the application of a formula for information. The idea
of a controlling servo-mechanism, the design for a mechanical brain, and
the assumption that nerves hold information, all make logical sense only
following Wiener's leap of faith.
Again, the bomb as it was to be
understood during the Cold War enters the epistemological shift. Wiener's
work during World War II contributed to one of the most advanced features
of the bomb. He assisted in developing a cybernetic servo-mechanism for
delivering a warhead from remote, safe bunkers across the ocean. This sterilized
version of human destruction was made possible by advances in guidance
systems and ballistics that evolved from Wiener's involvement. Wiener's
first application of cybernetics and Wiener numbers (set numbers to replace
the stochastic) was the development of a feedback mechanism used in the
tracking system for anti-aircraft gunnery, and by extension, the guidance
and delivery systems for rockets and missiles. These guidance servo-mechanisms
were the first primitive cybernetic computers. They were "thinking machines"
that responded to their environment; black boxes that became standard in
all missiles of the Cold War.
