[This is a chapter in an unpublished book of mine titled What Does Life Want?]
What a piece of work is man! How noble in
reason! how in-finite in faculty! in form, in moving, how express and admirable!
in action how like an angel! in apprehension how like a god!
William
Shakespeare in Hamlet
Just as we were coming in for a landing on the Planet of the
Robots, a peculiar cyclone very common there—but we didn’t know about these
then—caught our ship and caused it to crash. In the process our life-capsule
was thrown free and crashed into a nearby jungle. It split open as it fell,
but, fortunately, we could breathe the local air. Still, it took us the better
part of a day to get used to the gravity and make it back to the crash-site. By
then the VN robots were already crawling all over our ship. We tried to
communicate with them, but they ignored us. It seems they cannot recognize
intelligence in organic forms of life. One of our crew, Josephine—she will be
speaking next—thinks that they pay about as much attention to us as Texans do
to dust devils. By day they go into a dormant stage—call it sleep—while they
recharge their batteries in sunlight. We used their periods of rest to secure
as much food and water as we could and hid our supplies in the jungle.
VN robots are descendants of John Louis von Neumann’s
self-replicating machines that Dr. Carpov Lovestrange implemented in the 21st
century and sent out into space in a mad experiment. These creatures have
evolved somewhat and look like spiders about the size of palm pads. Lovestrange
was a miniaturizer, as you may recall. They communicate in digital shrills and
buzzes that decode into Esperanto. We began to study Esperanto like crazy
ourselves to see what they were up to. During the first several days we also
stole radio and computing equipment—and then watched in amusement as they
gathered and had fits, trying to discover who was stealing all these things and
disturbing their careful disassembly of our ship. We would just stand or sit
around, watching them work. They saw us as if we were walking reeds or bushes
and never suspected us. Later on they set a guard by day, but by that time we
had all that we required, and we could monitor not only their speech but also
the broadcasts from their distant media.
We gathered right away that our ship was deeply meaningful
for them. It was another life-form like themselves, but they called it
Mechanism. Later we heard news of this discovery spreading all over the VN
world.. Wise robots gathered from all over to try to explain it.
They have a peculiar thing here called the robotic method.
Their own reproductive cycles require the meticulous manufacture of many parts,
assembled into aggregates, the aggregates into clusters, the clusters into the
finished VN. You can’t call it a “baby” because it is the same size as adults,
but its silicone memory is still empty at birth. The last thing they do is make
and insert the solar battery. Then the young VN is set out in the sun to
charge. The next evening it comes alive, and the ants all gather round to chirp
and buzz their Happy Birthdays in Esperanto. Touching, in a way.
The robotic method of understanding is the reverse of this
process. They began almost at once disassembling our damaged rocket ship. They
would take each disassembly and gather around. They would buzz and shrill for
nights on end, until the understood the function of the thing at last. Then on
to the next disassembly.
We watched this in amazement—and with growing concern. It
didn’t look like we would ever get off the Robot Planet. Gloomily we began to
settle into a primitive sort of stone-age village ourselves—but with our
computers still functioning and our radios tuned to the VN broadcasts in the
mornings, which were their evenings.
Day by day we heard ever more hopeful news. The theorists
back home and the experimentalists out at our site met every morning for public
seminars on the Meaning of Mechanism. Some of them called it Alien Mechanism,
in contrast to their own. Some said that all Mechanism was quite similar, all
over the cosmos. At last they proclaimed that they had discovered the answer to
the puzzle of this form of Mechanism. They understood everything deeply
now—rocketry, navigation, propulsion, heating and cooling, the recycling of an
internal atmosphere—although that particular function still remained a little
problematical—cybernetics, everything. This mechanism had evolved for take-offs
and for landings. Their speculations ended there. They never asked obvious
questions. Why did this thing lift and land? They seemed not to wonder. Lifting
and landing seemed aim enough. Now they knew how it was done. For them the How
answered the Why.
Then, to our amazement, they began to reassemble the
rocket—hoping, perhaps, that it would come alive. With the greatest of care and
precision—staging their own rather clever machines to help them and swarming
over our rocket in their thousands—they put everything back together. Their
sharp vision saw where damage had curtailed the rocket’s function. They
repaired it. They analyzed the nature of our tanks of hydrogen and oxygen,
inferred what gases had been stored in our tanks in liquefied form. They built
refineries, extracted oxygen from the air and hydrogen from brackish evil pools
around the edges of the jungle. They refilled our tanks.
One fine morning, after they had all gone to sleep, we just
marched back into our ship, closed the portals, turned on our rockets, and we
got the hell off the Planet of the Robots, and here we are again.
And now, ladies and gentlemen, we’ll show you some slides.
And after that Josephine will talk about the culture of the VN robots and their
peculiarly limited mentation. Not to steal her thunder, in any way, but the
original von Neumann model, which, in a way, resembles our cellular
construction, clearly failed to anticipate something inherent in organic nature.
These mechanical creatures seem content with solving technical problems and,
proud of their superb technical gifts, they never even wonder what machines are
for.

Some 400 years after Shakespeare’s time, Francis Crick,
co-discoverer of DNA’s structure, issued his own fatwa, as it were. Writing in The Astonishing Hypothesis, he said:
“You, your joys and your sorrows, your memories and your ambitions, your sense
of personal identity and free will, are in fact no more than the behavior of a
vast assembly of nerve cells and their associated molecules.”
Imagine that you are a religious sort of person, and then
note the phrasing, the rhetoric. The statement recalls Bertrand Russell’s
lament, but adds an edge. First comes the recital of what might be considered
of most value to ordinary humans, their joys, sorrows, freedom, and their
memories. Next comes a dismissive flourish. “No more than,” Francis Crick says.
These words were issued in 1994. By that time modern psychology had long
abandoned the notion of free will—but not so ordinary man. But here it is again,
tossed away by Francis Crick, again, for emphasis.
The edge one hears in this, the cut of the lash of a whip a
religious person is likely to feel, is confirmed by John William Schmidt, one
re-viewer of the book. He says: “Crick is confrontational in his approach and
challenges religious believers with the idea that there is a scientific view of
the soul as being just one more manifestation of brain physiology.”*
Carl Gustav Jung, the famed Swiss psychologist, used to note
this attitude in his writings. He spoke of it as the nichts als approach to complex phenomena. The phrase translates to nothing but.
One wonders about the psychology behind such
“confrontational” pronouncements. Earlier in his review of Crick’s book,
Schmidt provides what might be a clue to motive. He says, “I am in agreement
with [J.J.] Hopfield that Crick’s book is a heroic attempt to wrest
consciousness from the minds of philosophers and place it in the hands of
science.”
I ponder this and my imagination produces interesting images.
If this interpretation is correct, we’re not really dealing with science here.
We’re not just hearing a learned presentation about the brain and how it works.
We might be dealing with an assertion of power and authority. I see things
morphing in my mind. Here is the brave little David of science, confronting
Goliath in the shape of the Church—and we’re back in the 16th century.
Gradually David morphs into an oppressive giant himself. And we’re now into the
late 21st century. Meanwhile the church has shrunk into a pygmy holding a bible
and singing a hymn. Goliath is about to take his vengeance. All your joys and
all your sorrows…
My imagination offers the picture of another confrontation.
On one side is a peasant, on the other the tight hose of nobility, the silk and
lace, the scented handkerchief held to the haughty nose under the sweeping hat.
All those neurons are really firing in my brain.
The nobleman proceeds. He explains a wedding cake by saying
that it is in fact no more than the behavior of vast assemblies of molecules of
flour, butter, baking powder, sugar, eggs, and heat. John Blue, the peasant,
thinks that Sir Francis is rather missing the point. Even to say that the cake
is mere nutrition is to miss the point. But the peasant dare not say it. After
all Sir Francis won the Nobel Prize, and the peasant just has a job—if he is
lucky.
Statements such as Francis Crick’s can be multiplied ad libitum. One often senses the same
animus. As Shakespeare said: “Methinks he protests too much.” The letters of the
Shakespearean quotation at the head of this chapter are made up of the letters
of the alphabet. The letters are formed by organic pigments clinging by
chemical bonds to cooked wood fibers and clay. They are no more than that,
etc., etc. We have nothing against the gentlemen and ladies of the paper
industry or that part of chemicals that manufactures inks—but the point, after
all, is the meaning of the words, not how they got to be where they are. The
meaning could not be communicated without the pigments and fibers in our case.
They are intertwined. But there is a hierarchy. And if the ladies and the
gentlemen of industry rose up in robes and pontificated, saying that the words
are nothing more than paper and ink, we’d boo.
One wonders. What is Big Bad science, creator of the atom
bomb, afraid of? Is it angry that, working within its own limiting rules, it
can only obtain limited answers? Is it right to smite the little people who try
to find some answer to life’s mystery—without the gentry’s by-your-leave? Must
they bow heads before their lordships, kiss the gloved hand, and shuffle
backwards? Is their humble adherence to consoling faith lèse-majesté?
Writing elsewhere, in Life
Itself: Its Origin and Nature, a book trying to prove that life originated
in another solar system and was sent to earth by rocket ship, Francis Crick
virtually confesses his disdain not only for ordinary people but also for
politicians, journalists, and philosophers. Reading him, one sees that he, the
lonely scientists, is actually the victim. One feels a tear forming in one’s
eye.
Let’s look a little more closely at reductionism. When
Einstein began to develop his theory of relativity, he made the assumption that
matter in the universe is evenly distributed in space. That’s a simplification.
The actual distribution of matter in the universe, on average, is a reasonable approximation to that
assumption, but it’s only true on average and over vast regions of space. The
matter in the solar system is not evenly distributed. The vast majority of
particles reside inside the sun. Matter thins out after that, bulging here and
there into planets. A genuinely even distribution would call for one atom of
matter in every cubic meter of space, but the simplification was good enough
for Einstein, and he produced great insights into physics.
It is a somewhat radical reduction to say that all language
is just sound, but those who begin to study language might wish legitimately to
start there—if not to end there. If they end there, that’s reductionism.
Reduction to absurdity comes about when the fundamental
relation-ships and consequences of a phenomenon are abstracted away, not just
temporarily, to achieve results, but permanently. Thus it is reductio ad absurdum to say that life is
nothing more than chemical reactions—or to say that human intelligence is just
cellular behavior. Far too much is left out.
Mankind has had this tendency to over-simplify, whatever the
motive. Long ago, already, correctives had been fashioned. Aristotle, for
instance, analyzed the diversity of phenomena and postulated four kinds of
causes to understand things comprehensively. Everything has a material cause, he said. Material causes
explain the physical basis of objects. What are they made of? Things have a formal cause, he said. The formal cause
of an object is its structure or design. How it is organized. Every object has
an agent that causes it to be; the agent can be animate or inanimate. Aristotle
labeled this the efficient cause—the
maker or the builder. Finally, he said, an object has a final cause. By that he meant its purpose or its function. Until
all four causes are adequately determined, a thing or phenomenon cannot be said
to be understood. The causes, of course, are all related.
If we apply these categories to life as it is currently
defined by science, we get the following:
Material cause: Chemicals.
Formal cause: Complexity
sustained by energy.
Efficient cause: Chance.
Final cause: Survival
and Multiplication.Put in this way, we see some weaknesses in the scientific explanation. At the least we are left feeling incomplete and disconnected. Why would Chance lead to an intentional activity like survival? The ancients taught that an agent’s potency had to be equal to the agent’s act—thus cold could not produce heat and the random could not produce order. Aristotle understood the second law of thermodynamics. I myself have no problem with the material and the formal cause as identified by science. But the urge to survive and multiply seems incompatible with the efficient cause, Chance. The efficient cause appears to be defective. Survival as the final cause of life is equivalent to saying that the final cause of cars is “rolling”—or, as in our little entertainment, to say that the rocket’s final cause is to make take-offs and landings. The cell is much too well designed to let Chance take all the glory. I would feel better if we just labeled the efficient cause “Unknown.” To say that is not to affirm “creation” in the fundamentalist sense. But it allows for a much better explanation later.
Putting things in this way, using ancient categories,
sharpens our view of how science sees life—and, by one remove, how it sees
human consciousness. To the extent that science asserts its findings
dogmatically, it also insists on the meaninglessness of the world. If science
contents itself with providing provisional conclusions based on sensory data,
the results are excellent. But when it attempts to “wrest consciousness from
the minds of philosophers and place it in the hands of science,” it is doing
something illegitimate.
It’s a trick unworthy of the noble enterprise of science.
The haughty lord first defines mind as the wiggling of trillions of cells.
Moreover, the lord asserts, it is nothing more than that. Next he adds that the
final cause of all this wiggling is nothing more than the survival of the
fittest.
John Blue listens to this with an open mouth. Ah, his mind
is slow. Slow, slow, slow. But in time, as he listens, things occur to him. If
what the haughty lord is saying is the truth, the mighty lord’s own speaking
mind is nothing more than the same sort of wiggling stuff. Isn’t it, now? Isn’t
it? And the words will only be spoken because they help the lord’s own personal
survival.
A light dawns in John Blue’s mind. He is just making a
discovery himself. His own trillions of wiggling cells don’t like the haughty
lord too much. What John hears the proud lord saying is that the things John
values most are nothing, meaningless. Pointless. Contemptible. Nothing that the
lord is saying indicates that his
cells are better than John’s own. Who’s to sit in judgement between John Blue
and Lord Francis? Another mind made up of trillions of wiggling cells?
John Blue has heard enough. There are a lot more people who
feel like he does. If little fireflies or little worms are all there is to it,
there is no truth, no higher principle, and therefore no point in standing here
and listening to the supercilious lord. John Blue turns and walks away, and the
lord finds himself speaking to the wind.
Which makes the proud lord angwy.

Narrow doctrinaire science—scientism—fails, both
philosophically and socially, by its own logic. Consider the following:
If the human brain has evolved as the most powerful brain on
this planet, it must be because it is most fit for life. It reasons powerfully
from causes to ends and is not satisfied with partial answers. A murder isn’t
solved when the detective writes on his report: “The knife went in and severed
the jugular.” The salesman who says, “Hey, this baby rolls,” doesn’t sell too
many cars.
Something about this brain, this supreme product of
evolution, demands meaning and closure. It wants hope. “There you go again,”
Science says, “deceiving yourself. Your hope is nothing but wishful thinking.
But I will grant you this—it helps you to survive.” In the usual context, this
sounds sophisticated. It sounds knowing and adult. Some people are attracted by
this view and wish to associate themselves with it. But many human brains, like
the child’s, go right on questioning. “Never mind me,” John Blue says.
“Survival can’t be an end in itself. What’s the point? I struggle so that my
kid can struggle—so that his kid can struggle? On and on? And I remember. At
the last lecture, under this same tree, you said that everything in the world
will eventually run down. Not good enough.”
There is a social downside to the reductionist view. If the
old philosophy is banished or, relinquishing its preeminence, accepts science’s
limitations too, weaknesses appear in our structure of values. The very force
of life is disordered if its proudest, noblest product is denied its proper
functioning.
Fëdor Dostoevski provided, perhaps, the ultimate reason why
we should ask ultimate questions. “If God does not exist,” he said,
“every-thing is permitted.” If the universe lacks closure, it lacks all
meaning. In a meaningless universe, we’re altogether on our own. We might as
well grab all the gusto that we can. You only go round once. The pleasure
principle must rule. Ethics become entirely relative. Only naked power can
restrain us, ultimately. If those who wield it harshly abuse it, there is no
logical reason why they shouldn’t. “Where there is no vision, the people
perish,” says Proverbs 29:18. Morality and social order are not so much ends in
themselves as by-products of vision. The Why Question is an attempt to find it.
Mankind, a collective of John and Jane Blues, embraces a
transcendental model, however abstractly or confusedly expressed. We are
forever judging things (ignoring the Logical Positivists). We use
transcendental principles of fairness and justice. We reject the doctrine of
“might is right.” We adhere to a hierarchical structure of values. We hold
those in highest veneration who preached Love as the supreme principle.
Is the universe inferior to us?
