All the limitative Theorems of metamathematics and the theory of computation |
suggest that once the ability to represent your own structure has reached a certain critical |
point, that is the kiss of death: it guarantees that you can never represent yourself totally. |
Godel’s Incompleteness Theorem, Church's Undecidability Theorem, Turing's Halting |
Theorem, Tarski's Truth Theorem-all have the flavor of some ancient fairy tale which |
warns you that "To seek self-knowledge is to embark on a journey which ... will always |
be incomplete, cannot be charted on any map, will never halt, cannot be described." |
But do the limitative Theorems have any bearing on people? Here is one way of arguing |
the case. Either I am consistent or I am inconsistent. (The latter is much more likely, but |
for completeness' sake, I consider both possibilities.) If I am consistent, then there are |
two cases. (1) The "low-fidelity" case: my self-understanding is below a certain critical |
point. In this case, I am incomplete by hypothesis. (2) The "high-fidelity" case: My self¬ |
understanding has reached the critical point where a metaphorical analogue of the |
limitative Theorems does apply, so my self-understanding |
undermines itself in a Godelian way, and I am incomplete for that reason. Cases (1) and |
(2) are predicated on my being 100 per cent consistent-a very unlikely state of affairs. |
More likely is that I am inconsistent-but that's worse, for then inside me there are |
contradictions, and how can I ever understand that? |
Consistent or inconsistent, no one is exempt from the mystery of the self. |
Probably we are all inconsistent. The world is just too complicated for a person to be able |
to afford the luxury of reconciling all of his beliefs with each other. Tension and |
confusion are important in a world where many decisions must be made quickly, Miguel |
de Unamuno once said, "If a person never contradicts himself, it must be that he says |
nothing." I would say that we all are in the same boat as the Zen master who, after |
contradicting himself several times in a row, said to the confused Doko, "I cannot |
understand myself." |
Godel’s Theorem and Personal Nonexistence |
Perhaps the greatest contradiction in our lives, the hardest to handle, is the knowledge |
"There was a time when I was not alive, and there will come a time when I am not alive." |
On one level, when you "step out of yourself" and see yourself as "just another human |
being", it makes complete sense. But on another level, perhaps a deeper level, personal |
nonexistence makes no sense at all. All that we know is embedded inside our minds, and |
for all that to be absent from the universe is not comprehensible. This is a basic |
undeniable problem of life; perhaps it is the best metaphorical analogue of Godel’s |
Theorem. When you try to imagine your own nonexistence, you have to try to jump out |
of yourself, by mapping yourself onto someone else. You fool yourself into believing that |
you can import an outsider's view of yourself into you, much as TNT "believes" it |
mirrors its own metatheory inside itself. But TNT only contains its own metatheory up to |
a certain extent-not fully. And as for you, though you may imagine that you have jumped |
out of yourself, you never can actually do so-no more than Escher's dragon can jump out |
of its native two-dimensional plane into three dimensions. In any case, this contradiction |
is so great that most of our lives we just sweep the whole mess under the rug, because |
trying to deal with it just leads nowhere. |
Zen minds, on the other hand, revel in this irreconcilability. Over and over again, |
they face the conflict between the Eastern belief: "The world and I are one, so the notion |
of my ceasing to exist is a contradiction in terms" (my verbalization is undoubtedly too |
Westernized-apologies to Zenists), and the Western belief: "I am just part of the world, |
and I will die, but the world will go on without me." |
Science and Dualism |
Science is often criticized as being too "Western" or "dualistic"-that is, being permeated |
by the dichotomy between subject and object, or observer |
and observed. While it is true that up until this century, science was exclusively |
concerned with things which can be readily distinguished from their human observers- |
such as oxygen and carbon, light and heat, stars and planets, accelerations and orbits, and |
so on-this phase of science was a necessary prelude to the more modern phase, in which |
life itself has come under investigation. Step by step, inexorably, "Western" science has |
moved towards investigation of the human mind-which is to say, of the observer. |
Artificial Intelligence research is the furthest step so far along that route. Before AI came |
along, there were two major previews of the strange consequences of the mixing of |
subject and object in science. One was the revolution of quantum mechanics, with its |
epistemological problems involving the interference of the observer with the observed. |
The other was the mixing of subject and object in metamathematics, beginning with |
Godel's Theorem and moving through all the other limitative'Theorems we have |
discussed. Perhaps the next step after Al will be the self-application of science: science |
studying itself as an object. This is a different manner of mixing subject and object- |
perhaps an even more tangled one than that of humans studying their own minds. |
By the way, in passing, it is interesting to note that all results essentially |
dependent on the fusion of subject and object have been limitative results. In addition to |
the limitative Theorems, there is Heisenberg's uncertainty principle, which says that |
measuring one quantity renders impossible the simultaneous measurement of a related |
quantity. I don't know why all these results are limitative. Make of it what you will. |
Symbol vs. Object in Modern Music and Art |
Closely linked with the subject-object dichotomy is the symbol-object dichotomy, which |
was explored in depth by Ludwig Wittgenstein in the early part of this century. Later the |
words "use" and "mention" were adopted to make the same distinction. Quine and others |
have written at length about the connection between signs and what they stand for. But |
not only philosophers have devoted much thought to this deep and abstract matter. In our |
century both music and art have gone through crises which reflect a profound concern |
with this problem. Whereas music and painting, for instance, have traditionally expressed |
ideas or emotions through a vocabulary of "symbols" (i.e. visual images, chords, |
rhythms, or whatever), now there is a tendency to explore the capacity of music and art to |
not express anything just to be. This means to exist as pure globs of paint, or pure sounds, |
but in either case drained of all symbolic value. |
In music, in particular, John Cage has been very influential in bringing a Zen-like |
approach to sound. Many of his pieces convey a disdain for "use" of sounds-that is, using |
sounds to convey emotional states-and an exultation in "mentioning" sounds-that is, |
concocting arbitrary juxtapositions of sounds without regard to any previously formulated |
