Neal Stephenson, Anathem. New York: William Morrow, 2008.
Reviewed by John Bedell The
leading literary spokesman for the technogeek class is back with
another very long, very interesting book. I read all 890 pages in less
than two weeks, which, considering that I have five children and a job,
implies a pretty high degree of focus. I think it’s great.
Anathem
is set on a planet much like the earth. The 18-year-old narrator and
the other main characters inhabit the Concent of Saunt Edhar, a sort of
monastery for mathematicians and philosophers – “saunt,” we are told,
is a shortened form of “savant.” In this world the scientific elite is
separated from the general population and forbidden to use computers or
most other technology. Unable to do experiments, they devote themselves
to “theorics,” which means mostly higher math, astronomy, and the
philosophy that undergirds them. They have an elaborate ritual life and
have raised their music, which is much like the chanting and singing of
monks, to a high art. They grow their own food and manage their own
affairs. The avout, as these mathematical monks are called, are divided
into four classes, based on how frequently they interact with the
secular world. The Unarians open their doors once every year, the
Decenarians once every ten, the Centennarians once a century, and the
Millenarians once a thousand.
The complex, 3000-year
relationship between the secular and “mathic” worlds is laid out in
some detail (you can give a lot of background in 890 pages). It seems
that 700 years or so before our story civilization had grown wealthy
and technologically advanced but destroyed itself through war and
ecological disaster. Much of the blame was placed on the scientists who
created the superweapons used in these wars, so they were banished to
their “maths” and the separation between the two worlds was rigidly
enforced. Since then the secular world has been relatively peaceful but
technologically and economically stagnant, while the mathic world has
gotten caught up in abstruse and unresolvable philosophical debates.
Much of Anathem
moves quite slowly. The plot doesn’t really get going until page 250 or
so, and after that there are more long patches in which very little
happens. I kept reading because I found the world fascinating and
because the characters talk about interesting things. Stephenson’s
world is full of marvelous details. He has developed an extensive
vocabulary that helps make the world feel different from earth despite
the similarities. Data is “givens,” videos are called “speelies,” and
video cameras are “speelycaptors.” The sociology is particularly
interesting, such as the ways different seculars feel about the avout.
Some consider the avout useless fuddy-duddies, some think they are evil
sorcerers, some think they have special contact with god. I never
minded that little was happening, because for me just exploring this
world was enough.
The plot, once it gets going, it pretty
interesting. I’m not going to say anything about it, because it relies
on surprises I don’t want to spoil and because it isn’t really the main
point of the book anyway. The most important section of the book, I
thought, was a hundred-page-long discussion revolving around the
speculation that the many-worlds interpretation of quantum mechanics
explains consciousness. The plot follows out certain very far-fetched
real-world consequences of this idea. I didn’t always like the way
Stephenson did this but, hey, this is what science fiction is about:
what might happen if this crazy but possible scientific notion were
true? Stephenson shows himself to be a master of this kind of writing.
The
many worlds interpretation grew out of the frustration physicists have
felt when they try to connect the mathematics of particle physics to a
logical narrative of what is happening in the world. Quantum physics
gives no absolute account of where things are or what state they are
in, just probabilities. An electron might be just about anywhere in the
universe; in quantum mechanics it doesn’t have a location, just a sort
of cloud of probability. Nor is this just the vagueness of a guess. In
some kinds of experiments the electron seems to be smeared out in
space, for example, passing simultaneously through two holes in a
screen. In other cases an electron seems to be in two places at once,
or to have two different spin states at the same time. But if you look
for the electron, for example by bouncing an x-ray off it, it has a
definite location. What happens to the probability cloud that it
appeared to be a millisecond before?
Nobody knows. Textbooks
say that the wave function of the electron, which describes that
smeared-out probability cloud, has “collapsed” to one point. As I
understand it, nobody has been able to model this collapse in a
rigorous mathematical way, and physicists have grown increasingly
uncomfortable with the textbook description. So they have tried some
very weird ways to make sense of the quantum world. The many worlds
interpretation asserts that, in fact, every possible outcome does
happen. Every time someone measures the spin state of an electron or
measures its exact location, the world divides into many worlds, with
each possible outcome happening in one of those worlds. The many worlds
interpretation has some obvious problems. First of all, it seems
impossible almost by definition to ever prove that it is true or false,
which according to the standard definition means that it isn’t really
science. There is also the Schroedinger’s cat problem: what kind of
event triggers the division of the cosmos into different “world
tracks”? And what about probability? What does it mean to say that one
outcome is more likely than another if, in fact, every possible outcome
does happen? But for Neal Stephenson’s purposes as an author, and ours
as readers, it is enough that a great many scientists find the idea
intriguing.
I had never before encountered the connection
between the many worlds interpretation and consciousness, but since it
seems, once you hear it, rather obvious, I assume that Stephenson
didn’t invent the model he proposes. (One of his characters notes that
people have been speculating on these topics for a thousand years.) The
idea goes something like this: one way to define consciousness is to
think of it as the ability to hold different models of the future in
our minds at the same time. When we think about what to do, we imagine
the consequences of different actions. We also think about the past,
wondering how things might be different if we had made different
choices. In the terms sometimes used by physicists, we are holding in
our minds separate world tracks; as some philosophers have put it, we
live extended in time. Recall that it is possible for subatomic
particles to be, or at least to appear to be, in two different states
at the same time. Such a particle exists simultaneously in two separate
world tracks. This is the property that would be taken advantage of by
quantum computers, should they ever be created: a transistor that can
be in two states at once can do a lot more work than one that has to be
in one state or the other. What if, this speculation proceeds, our
brains work that way? If we hold different models of the future in our
minds using the quantum properties of electrons in our brains? Why,
then we are quantum computers, and our brains are able to travel some
distance along parallel world tracks, existing for at least a short
time in multiple universes. This ability to exist simultaneously in
parallel universes defines consciousness, or at least is a key part of
it, and it makes our minds fundamentally different from ordinary
computers.
Whatever you think of this model, in Stephenson’s
hands it makes for some fascinating conversation among his characters
and some wonderfully bizarre happenings. (Suppose there were people who
learned to travel along separate world tracks for more than the
microseconds that most of us can, perhaps for hours or days; might not
this ability to follow out the consequences of actions until they
become clear before choosing one seem like a kind of sorcery?) If
you think you might like reading a novel that mixes conversations on
such matters with some intense action and the exploration of a very
cleverly imagined world, run out and get a copy of Anathem. If not, well, read something else.
One
of the things I find most interesting about Stephenson as a writer is
that he so clearly defines himself as a particular kind of person,
writing for those like himself. He knows a lot about digital technology
and something about math, and he looks down on those who don’t.
Government comes across as a sort of conspiracy set up by those without
technical knowledge to control those who do, and to take some of the
wealth they create and distribute it to people who have done nothing to
deserve it. Stephenson’s bestselling book so far, Cryptonomicon,
features a lot of straight out anarcho-libertarian fantasy. Characters
live in fortified compounds on lightly governed islands, their privacy
protected from government snooping by strong cryptography, their money
shielded from taxation in a completely secret international internet
bank. Government agents and especially lawyers appear as irrational,
power-mad goons. Brilliant codebreakers exploit the ignorance of their
military bosses to carry out their own diplomatic policies, along the
way making fools of those same bosses with practical jokes that the
generals never even understand.
Compared to the world of Cryptonomicon,
Stephenson’s new world shows some of the same tendencies, but in a more
nuanced way. It seems less juvenile, less like the sort of thing
dreamed up by a 20-year-old fan of Ayn Rand. Since it is presented in a
more grown-up and serious way, it seems fair to treat the philosophy
espoused here seriously, and to ask whether it has any value.
Stephenson puts a very high value on rational, scientific thought. In Anathem he allows some value to poetry, but in all his books he heaps abuse on religion. In one of my favorite moments in Anathem,
the narrator has a discussion with a religious believer about Saunt
Bly, a famous character who, centuries before, had left his math and
ended up as the focus of a religious cult. The “deolater” says that he
believes that Saunt Bly was expelled from the concent because he proved
the existence of god. “That’s interesting,” says the narrator, “because
what would really happen is that we would say ‘nice proof, Bly’ and
start believing in god.” At a wedding, the deolater preacher gave
“one of his exasperating sermons, filled with wisdom and upsight and
human truths, fettered to a cosmographic scheme that had bee blown out
of the water four thousand years ago.” It was nice to see that
Stephenson has created some interesting god-believing characters who
come across as generally positive, but in the end they still suffer
from that silly weakness, the inability to think in a rational and
rigorous way.
The secular powers get a similar treatment. Some
individual politicians are educated and sensible, and individual
soldiers come across as decent guys who are very useful in an
emergency, but on the whole government is a deeply frivolous
enterprise. The leading avout understand the world so much more
profoundly than the “panjandrums” that the notion of their following
secular orders is a joke. Even the 18-year-old narrator is wiser than
the political class.
I have nothing against intelligence and
education, and I am myself a big fan of rational, scientific thought.
But that is far different from the claim that the technical elite
should rule the world. Stephenson seems to think that there is nothing
to government but intelligence and rationality. I was reminded of the
claim, made by the King of the Brobdignacians in Gulliver’s Travels,
that there is nothing to government but goodness and common sense. But
it simply is not true that scientists, even the greatest, have any
special wisdom when it comes to politics. George Orwell, confronted by
the claim that a more scientific education would make the English
better citizens, asked why, if that was so, so many scientists of the
1920s and 1930s became communists and Nazis. In fact, over the past
century highly educated, philosophically minded people have been drawn
to radical politics in much greater numbers than the populace at large.
In America we haven’t had a lot of communist scientists, but we have
had our share of racists, John Birchers, and similar lunatics. Here’s a
question to ponder: which group, scientists or ministers, has been a
more important force for political good in America?
I would say
that Stephenson’s own politics disprove his notion that the elite has
more wisdom than the masses. Of all the competing political
philosophies in the world, I think libertarianism is the stupidest. We
cannot survive without government. Even Stalinism, for all its horrors,
managed to work for a while. Libertarianism would never work at all. We
could certainly get by with a lot less government than we have now, and
I am attracted to libertarian positions on several issues. But the
notion that we could get by without a strong state is simply
nonsensical. Too see what would happen, you have only to look at what
happened in Europe when the Roman Empire collapsed. The economy
collapsed with it, the population cratered, and the survivors mostly
ended up as serfs of powerful lords or great churches. Without a
government stronger than the corporations, we would all end up as the
serfs of corporate masters, or of individual billionaires.
Yeah,
ok, it’s a novel, and I am once again indulging my habit of taking
everything too seriously. But it’s Neal Stephenson’s own fault. By
incorporating so much fascinating, high-level discussion of ideas into
this terrific book, he has put me in a reflective, thoughtful frame of
mind. How many entertaining books can do that?
