- Turing and the Apple
by Giulio Giorello
The apple has always had a certain
importance in the history of mankind. There
was the apple that Eve picked and Adam ate,
and we have seen the consequences. There was
the apple that fell on Newton’s head –
an episode he himself liked to relate in later
years – and we are now grappling with
the enigma of gravity. There is also Alan Turing’s
poisoned apple. Let’s stop here. Alan's
Apple-Hacking the Turing Test by Valeria Patera
examines the scandal surrounding this last apple
and presents as an enigma the life, death and
destiny of the man who did so much to decipher
the Nazi Enigma code during the Second World
War. But deciphering the meaning of life is
much more difficult.
Patera counterpoints the human and scientific
aspects of Alan Turing’s life with conversations
between two hackers who, in their turn, question
the meaning of what they do. They set the virtual
world of the Net against the real world, composed
of things and bodies, but also of institutions
like the Inland Revenue and the Police. Here,
as in Turing’s case, the focus is on diversity
as opposed to standardization, extraordinary
science as opposed to normal research, liberty
as opposed to necessity. But what if the freedom
dreamt of by those who surf the Net is actually
a different kind of necessity? Besides, I remember
one of the hackers saying at the beginning of
Patera’s play: “I live on the Net,
in another society, with its own rules, borders
and traditions.” Exactly! Here we have
another society, more rules and borders! We
may also have the slight suspicion that the
wonderful world imagined and desired by the
hackers will turn out to be a Brave New World.
Is there perhaps a test that would allow us
to clearly distinguish the different kinds of
freedom from those of necessity?
Turing’s own experiences show how difficult
it is to make a sharp distinction between the
two. Does science always signify intellectual
emancipation, and technology “progress”?
Then, why “are the Police so interested”?
To what kind of freedom did Turing sacrifice
the best years of his life? What kind of an
open society is it that uses chemical castration
to “normalize” those who appear
to be sexually “abnormal”? And can
machines be “better” than human
beings, in every sense of the word? In constantly
posing these questions, Patera cannot but use
as a poetic symbol the Turing Test itself, which
has become one of the most representative issues
in the soul-body-machine, or if you prefer,
the mind-brain-computer debate. A problem that
has been with as at least since the time of
Descartes. However it was abstract logic research
(the Turing concept of computability) that truly
revealed to us the Brave New World of the computer
technology; the technological aspect (the programme
known as Strong Artificial Intelligence) came
later; moreover, it was brilliantly anticipated
by Alan Turing Perhaps it is more than a historical
irony that the test which is indissolubly linked
to Turing’s name in specialist literature,
was based on a gender test (designed to reveal
if the hidden interlocutor was male or female).
As well as ambivalent sexuality there is now
an equally ambivalent human being. It suffices
to consult the documentation on the results
of the Turing Test. In the interesting volume
The Engine of Reason, the Seat of the Soul (1995)
by Paul M. Churchland, for example, we read
that in the course of many tests not one “machine”
was mistaken for a human being by the “judges”,
whereas many human beings were taken for machines
(see Chapter 9 of the above-mentioned work).
Perhaps it is not a question of asking ourselves
if a machine can think, but of concluding that
when we think we do so like “machines”.
Indeed, the hackers in Patera’s play give
us to understand that, in some sense of the
word, we are (also) machines. Extremely sophisticated
machines, in fact, that have undergone a long
evolutionary process. These machines are also
known as bodies, and perhaps Turing’s
error was to sometimes forget that he possessed
a body and that simulated intelligence is also
strongly conditioned by the physical structures
employed. Nowadays, the Turing Test is usually
criticized from two opposing points of view.
According to some it is too narrowly-based,
while others find it too broadly-based. In either
case it is not able to adequately represent
the kind of symbolic thought that is now considered
one of the most significant products of evolution,
firstly from a biological and secondly from
a cultural standpoint. I would refer the reader
here to the now well-known Chinese room argument
by John R. Searle. Patera obviously does not
claim to solve this philosophical puzzle in
her play; but she intelligently implies that
the symbol is the “death” of Turing’s
research programme.
Symbols are important, in fact, as the anecdotes
about apples show, and the one about Turing
is a little like the apple (poisoned) in Snow
White, the difference being that in Turing’s
story there is no prince charming to awaken
the sleeper with a kiss. In true Italian style
Patera concludes her play with Alan’s
mother saying: “I don’t believe
it.”
