Once upon a time, the planet was tyrannized by a giant dragon. The
dragon stood taller than the largest cathedral, and it was covered with
thick black scales. Its red eyes glowed with hate, and from its terrible
jaws flowed an incessant stream of evil-smelling yellowish-green slime.
It demanded from humankind a blood-curdling tribute: to satisfy its
enormous appetite, ten thousand men and women had to be delivered every
evening at the onset of dark to the foot of the mountain where the
dragon-tyrant lived. Sometimes the dragon would devour these unfortunate
souls upon arrival; sometimes again it would lock them up in the
mountain where they would wither away for months or years before
eventually being consumed.
The misery inflicted by the dragon-tyrant was incalculable. In
addition to the ten thousand who were gruesomely slaughtered each day,
there were the mothers, fathers, wives, husbands, children, and friends
that were left behind to grieve the loss of their departed loved
ones.
Some people tried to fight the dragon, but whether they were brave or
foolish was difficult to say. Priests and magicians called down curses,
to no avail. Warriors, armed with roaring courage and the best weapons
the smiths could produce, attacked it, but were incinerated by its fire
before coming close enough to strike. Chemists concocted toxic brews and
tricked the dragon into swallowing them, but the only apparent effect
was to further stimulate its appetite. The dragon's claws, jaws, and
fire were so effective, its scaly armor so impregnable, and its whole
nature so robust, as to make it invincible to any human assault.
Seeing that defeating the tyrant was impossible, humans had no choice
but to obey its commands and pay the grisly tribute. The fatalities
selected were always elders. Although senior people were as vigorous and
healthy as the young, and sometimes wiser, the thinking was that they
had at least already enjoyed a few decades of life. The wealthy might
gain a brief reprieve by bribing the press gangs that came to fetch
them; but, by constitutional law, nobody, not even the king himself,
could put off their turn indefinitely.
Spiritual men sought to comfort those who were afraid of being eaten
by the dragon (which included almost everyone, although many denied it
in public) by promising another life after death, a life that would be
free from the dragon-scourge. Other orators argued that the dragon has
its place in the natural order and a moral right to be fed. They said
that it was part of the very meaning of being human to end up in the
dragon's stomach. Others still maintained that the dragon was good for
the human species because it kept the population size down. To what
extent these arguments convinced the worried souls is not known. Most
people tried to cope by not thinking about the grim end that awaited
them.
For many centuries this desperate state of affairs continued. Nobody
kept count any longer of the cumulative death toll, nor of the number of
tears shed by the bereft. Expectations had gradually adjusted and the
dragon-tyrant had become a fact of life. In view of the evident futility
of resistance, attempts to kill the dragon had ceased. Instead, efforts
now focused on placating it. While the dragon would occasionally raid
the cities, it was found that the punctual delivery to the mountain of
its quota of life reduced the frequency of these incursions.
Knowing that their turn to become dragon-fodder was always impending,
people began having children earlier and more often. It was not uncommon
for a girl to be pregnant by her sixteenth birthday. Couples often
spawned a dozen children. The human population was thus kept from
shrinking, and the dragon was kept from going hungry.
Over the course of these centuries, the dragon, being well fed,
slowly but steadily grew bigger. It had become almost as large as the
mountain on which it lived. And its appetite had increased
proportionately. Ten thousand human bodies were no longer enough to fill
its belly. It now demanded eighty thousand, to be delivered to the foot
of the mountain every evening at the onset of dark.
What occupied the king's mind more than the deaths and the dragon
itself was the logistics of collecting and transporting so many people
to the mountain every day. This was not an easy task.
To facilitate the process, the king had a railway track constructed:
two straight lines of glistening steel leading up to the dragon's abode.
Every twenty minutes, a train would arrive at the mountain terminal
crammed with people, and would return empty. On moonlit nights, the
passengers traveling on this train, if there had been windows for them
to stick their heads out of, would have been able to see in front of
them the double silhouette of the dragon and the mountain, and two
glowing red eyes, like the beams from a pair of giant lighthouses,
pointing the way to annihilation.
Servants were employed by the king in large numbers to administer the
tribute. There were registrars who kept track of whose turn it was to be
sent. There were people-collectors who would be dispatched in special
carts to fetch the designated people. Often traveling at breakneck
speed, they would rush their cargo either to a railway station or
directly to the mountain. There were clerks who administered the
pensions paid to the decimated families who were no longer able to
support themselves. There were comforters who would travel with the
doomed on their way to the dragon, trying to ease their anguish with
spirits and drugs.
There was, moreover, a cadre of dragonologists who studied how these
logistic processes could be made more efficient. Some dragonologists
also conducted studies of the dragon's physiology and behavior, and
collected samples – its shed scales, the slime that drooled from its
jaws, its lost teeth, and its excrements, which were specked with
fragments of human bone. All these items were painstakingly annotated
and archived. The more the beast was understood, the more the general
perception of its invincibility was confirmed. Its black scales, in
particular, were harder than any material known to man, and there seemed
no way to make as much as a scratch in its armor.
To finance all these activities, the king levied heavy taxes on his
people. Dragon-related expenditures, already accounting for one seventh
of the economy, were growing even faster than the dragon itself.
Humanity is a curious species. Every once in a while, somebody gets a
good idea. Others copy the idea, adding to it their own improvements.
Over time, many wondrous tools and systems are developed. Some of these
devices – calculators, thermometers, microscopes, and the glass vials
that the chemists use to boil and distil liquids – serve to make it
easier to generate and try out new ideas, including ideas that expedite
the process of idea-generation.
Thus the great wheel of invention, which had turned at an almost
imperceptibly slow pace in the older ages, gradually began to
accelerate.
Sages predicted that a day would come when technology would enable
humans to fly and do many other astonishing things. One of the sages,
who was held in high esteem by some of the other sages but whose
eccentric manners had made him a social outcast and recluse, went so far
as to predict that technology would eventually make it possible to build
a contraption that could kill the dragon-tyrant.
The king's scholars, however, dismissed these ideas. They said that
humans were far too heavy to fly and in any case lacked feathers. And as
for the impossible notion that the dragon-tyrant could be killed,
history books recounted hundreds of attempts to do just that, not one of
which had been successful. "We all know that this man had some
irresponsible ideas," a scholar of letters later wrote in his obituary
of the reclusive sage who had by then been sent off to be devoured by
the beast whose demise he had foretold, "but his writings were quite
entertaining and perhaps we should be grateful to the dragon for making
possible the interesting genre of dragon-bashing literature which
reveals so much about the culture of angst!"
Meanwhile, the wheel of invention kept turning. Mere decades later,
humans did fly and accomplished many other astonishing things.
A few iconoclastic dragonologists began arguing for a new attack on
the dragon-tyrant. Killing the dragon would not be easy, they said, but
if some material could be invented that was harder than the dragon's
armor, and if this material could be fashioned into some kind of
projectile, then maybe the feat would be possible. At first, the
iconoclasts' ideas were rejected by their dragonologist peers on grounds
that no known material was harder than dragon scales. But after working
on the problem for many years, one of the iconoclasts succeeded in
demonstrating that a dragon scale could be pierced by an object made of
a certain composite material. Many dragonologists who had previously
been skeptical now joined the iconoclasts. Engineers calculated that a
huge projectile could be made of this material and launched with
sufficient force to penetrate the dragon's armor. However, the
manufacture of the needed quantity of the composite material would be
expensive.
A group of several eminent engineers and dragonologists sent a
petition to the king asking for funding to build the anti-dragon
projectile. At time when the petition was sent, the king was preoccupied
with leading his army into war against a tiger. The tiger had killed a
farmer and subsequently disappeared into the jungle. There was
widespread fear in the countryside that the tiger might come out and
strike again. The king had the jungle surrounded and ordered his troops
to begin slashing their way through it. At the conclusion of the
campaign, the king could announce that all 163 tigers in the jungle,
including presumably the murderous one, had been hunted down and killed.
During the tumult of the war, however, the petition had been lost or
forgotten.
The petitioners therefore sent another appeal. This time they
received a reply from one of the king's secretaries saying that the king
would consider their request after he was done reviewing the annual
dragon-administration budget. This year's budget was the largest to date
and included funding for a new railway track to the mountain. A second
track was deemed necessary, as the original track could no longer
support the increasing traffic. (The tribute demanded by the
dragon-tyrant had increased to one hundred thousand human beings, to be
delivered to the foot of the mountain every evening at the onset of
dark.) When the budget was finally approved, however, reports were
coming from a remote part of the country that a village was suffering
from a rattlesnake infestation. The king had to leave urgently to
mobilize his army and ride off to defeat this new threat. The
anti-dragonists' appeal was filed away in a dusty cabinet in the castle
basement.
The anti-dragonists met again to decide what was to be done. The
debate was animated and continued long into the night. It was almost
daybreak when they finally resolved to take the matter to the people.
Over the following weeks, they traveled around the country, gave public
lectures, and explained their proposal to anyone who would listen. At
first, people were skeptical. They had been taught in school that the
dragon-tyrant was invincible and that the sacrifices it demanded had to
be accepted as a fact of life. Yet when they learnt about the new
composite material and about the designs for the projectile, many became
intrigued. In increasing numbers, citizens flocked to the anti-dragonist
lectures. Activists started organizing public rallies in support of the
proposal.
When the king read about these meetings in the newspaper, he summoned
his advisors and asked them what they thought about it. They informed
him about the petitions that had been sent but told him that the
anti-dragonists were troublemakers whose teachings were causing public
unrest. It was much better for the social order, they said, that the
people accepted the inevitability of the dragon-tyrant tribute. The
dragon-administration provided many jobs that would be lost if the
dragon was slaughtered. There was no known social good coming from the
conquest of the dragon. In any case, the king's coffers were currently
nearly empty after the two military campaigns and the funding set aside
for the second railway line. The king, who was at the time enjoying
great popularity for having vanquished the rattlesnake infestation,
listened to his advisors' arguments but worried that he might lose some
of his popular support if was seen to ignore the anti-dragonist
petition. He therefore decided to hold an open hearing. Leading
dragonologists, ministers of the state, and interested members of the
public were invited to attend.
The meeting took place on the darkest day of the year, just before
the Christmas holidays, in the largest hall of the royal castle. The
hall was packed to the last seat and people were crowding in the aisles.
The mood was charged with an earnest intensity normally reserved for
pivotal wartime sessions.
After the king had welcomed everyone, he gave the floor to the
leading scientist behind the anti-dragonist proposal, a woman with a
serious, almost stern expression on her face. She proceeded to explain
in clear language how the proposed device would work and how the
requisite amount of the composite material could be manufactured. Given
the requested amount of funding, it should be possible to complete the
work in fifteen to twenty years. With an even greater amount of funding,
it might be possible to do it in as little as twelve years. However,
there could be no absolute guarantee that it would work. The crowd
followed her presentation intently.
Next to speak was the king's chief advisor for morality, a man with a
booming voice that easily filled the auditorium:
"Let us grant that this woman is correct about the science and that
the project is technologically possible, although I don't think that has
actually been proven. Now she desires that we get rid of the dragon.
Presumably, she thinks she's got the right not to be chewed up by the
dragon. How willful and presumptuous. The finitude of human life is a
blessing for every individual, whether he knows it or not. Getting rid
of the dragon, which might seem like such a convenient thing to do,
would undermine our human dignity. The preoccupation with killing the
dragon will deflect us from realizing more fully the aspirations to
which our lives naturally point, from living well rather than merely
staying alive. It is debasing, yes debasing, for a person to want to
continue his or her mediocre life for as long as possible without
worrying about some of the higher questions about what life is to be
used for. But I tell you, the nature of the dragon is to eat humans, and
our own species-specified nature is truly and nobly fulfilled only by
getting eaten by it..."
The audience listened respectfully to this highly decorated speaker.
The phrases were so eloquent that it was hard to resist the feeling that
some deep thoughts must lurk behind them, although nobody could quite
grasp what they were. Surely, words coming from such a distinguished
appointee of the king must have profound substance.
The speaker next in line was a spiritual sage who was widely
respected for his kindness and gentleness as well as for his devotion.
As he strode to the podium, a small boy yelled out from the audience:
"The dragon is bad!"
The boy's parents turned bright red and began hushing and scolding
the child. But the sage said, "Let the boy speak. He is probably wiser
than an old fool like me."
At first, the boy was too scared and confused to move. But when he
saw the genuinely friendly smile on the sage's face and the outreached
hand, he obediently took it and followed the sage up to the podium.
"Now, there's a brave little man," said the sage. "Are you afraid of the
dragon?"
"I want my granny back," said the boy.
"Did the dragon take your granny away?"
"Yes," the boy said, tears welling up in his large frightened eyes.
"Granny promised that she would teach me how to bake gingerbread cookies
for Christmas. She said that we would make a little house out of
gingerbread and little gingerbread men that would live in it. Then those
people in white clothes came and took Granny away to the dragon... The
dragon is bad and it eats people... I want my Granny back!"
At this point the child was crying so hard that the sage had to
return him to his parents.
There were several other speakers that evening, but the child's
simple testimony had punctured the rhetorical balloon that the king's
ministers had tried to inflate. The people were backing the
anti-dragonists, and by the end of the evening even the king had come to
recognize the reason and the humanity of their cause. In his closing
statement, he simply said: "Let's do it!"
As the news spread, celebrations erupted in the streets. Those who
had been campaigning for the anti-dragonists toasted each other and
drank to the future of humanity.
The next morning, a billion people woke up and realized that their
turn to be sent to the dragon would come before the projectile would be
completed. A tipping point was reached. Whereas before, active support
for the anti-dragonist cause had been limited to a small group of
visionaries, it now became the number one priority and concern on
everybody's mind. The abstract notion of "the general will" took on an
almost tangible intensity and concreteness. Mass rallies raised money
for the projectile project and urged the king to increase the level of
state support. The king responded to these appeals. In his New Year
address, he announced that he would pass an extra appropriations bill to
support the project at a high level of funding; additionally, he would
sell off his summer castle and some of his land and make a large
personal donation. "I believe that this nation should commit itself to
achieving the goal, before this decade is out, of freeing the world from
the ancient scourge of the dragon-tyrant."
Thus started a great technological race against time. The concept of
an anti-dragon projectile was simple, but to make it a reality required
solutions to a thousand smaller technical problems, each of which
required dozens of time-consuming steps and missteps. Test-missiles were
fired but fell dead to the ground or flew off in the wrong direction. In
one tragic accident, a wayward missile landed on a hospital and killed
several hundred patients and staff. But there was now a real seriousness
of purpose, and the tests continued even as the corpses were being dug
out from the debris.
Despite almost unlimited funding and round-the-clock work by the
technicians, the king's deadline could not be met. The decade concluded
and the dragon was still alive and well. But the effort was getting
closer. A prototype missile had been successfully test fired. Production
of the core, made of the expensive composite material, was on schedule
for its completion to coincide with the finishing of the fully tested
and debugged missile shell into which it was to be loaded. The launch
date was set to the following year's New Year's Eve, exactly twelve
years after the project's official inauguration. The best-selling
Christmas gift that year was a calendar that counted down the days to
time zero, the proceeds going to the projectile project.
The king had undergone a personal transformation from his earlier
frivolous and thoughtless self. He now spent as much time as he could in
the laboratories and the manufacturing plants, encouraging the workers
and praising their toil. Sometimes he would bring a sleeping bag and
spend the night on a noisy machine floor. He even studied and tried to
understand the technical aspects of their work. Yet he confined himself
to giving moral support and refrained from meddling in technical and
managerial matters.
Seven days before New Year, the woman who had made the case for the
project almost twelve years earlier, and was now its chief executive,
came to the royal castle and requested an urgent audience with the king.
When the king got her note, he excused himself to the foreign
dignitaries whom he was reluctantly entertaining at the annual Christmas
dinner and hurried off to the private room where the scientist was
waiting. As always of late, she looked pale and worn from her long
working hours. This evening, however, the king also thought he could
detect a ray of relief and satisfaction in her eyes.
She told him that the missile had been deployed, the core had been
loaded, everything had been triple-checked, they were ready to launch,
and would the king give his final go-ahead. The king sank down in an
armchair and closed his eyes. He was thinking hard. By launching the
projectile tonight, one week early, seven hundred thousand people would
be saved. Yet if something went wrong, if it missed its target and hit
the mountain instead, it would be a disaster. A new core would have to
be constructed from scratch and the project would be set back by some
four years. He sat there, silently, for almost an hour. Just as the
scientist had become convinced that he had fallen asleep, he opened his
eyes and said in a firm voice: "No. I want you to go right back to the
lab. I want you to check and then re-check everything again." The
scientist could not help a sigh escaping her; but she nodded and
left.
The last day of the year was cold and overcast, but there was no
wind, which meant good launch conditions. The sun was setting.
Technicians were scuttling around making the final adjustments and
giving everything one last check. The king and his closest advisors were
observing from a platform close to the launch pad. Further away, behind
a fence, large numbers of the public had assembled to witness the great
event. A large clock was showing the countdown: fifty minutes to go.
An advisor tapped the king on the shoulder and drew his attention to
the fence. There was some tumult. Somebody had apparently jumped the
fence and was running towards the platform where the king sat. Security
quickly caught up with him. He was handcuffed and taken away. The king
turned his attention back to the launch pad, and to the mountain in the
background. In front of it, he could see the dark slumped profile of the
dragon. It was eating.
Some twenty minutes later, the king was surprised to see the
handcuffed man reappearing a short distance from the platform. His nose
was bleeding and he was accompanied by two security guards. The man
appeared to be in a frenzied state. When he spotted the king, he began
shouting at the top of his lungs: "The last train! The last train! Stop
the last train!"
"Who is this young man?" said the king. "His face seems familiar, but
I cannot quite place him. What does he want? Let him come up."
The young man was a junior clerk in the ministry of transportation,
and the reason for his frenzy was that he had discovered that his father
was on the last train to the mountain. The king had ordered the train
traffic to continue, fearing that any disruption might cause the dragon
to stir and leave the open field in front of the mountain where it now
spent most of its time. The young man begged the king to issue a
recall-order for the last train, which was due to arrive at the mountain
terminal five minutes before time zero.
"I cannot do it," said the king, "I cannot take the risk."
"But the trains frequently run five minutes late. The dragon won't
notice! Please!"
The young man was kneeling before the king, imploring him to save his
father's life and the lives of the other thousand passengers onboard
that last train.
The king looked down at the pleading, bloodied face of the young man.
But he bit his lip, and shook his head. The young man continued to wail
even as the guards carried him off the platform: "Please! Stop the last
train! Please!"
The king stood silent and motionless, until, after while, the wailing
suddenly ceased. The king looked up and glanced over at the countdown
clock: five minutes remaining.
Four minutes. Three minutes. Two minutes.
The last technician left the launch pad.
30 seconds. 20 seconds. Ten, nine, eight...
As a ball of fire enveloped the launch pad and the missile shot out,
the spectators instinctively rose to the tips of their toes, and all
eyes fixated at the front end of the white flame from the rocket's
afterburners heading towards the distant mountain. The masses, the king,
the low and the high, the young and the old, it was as if at this moment
they shared a single awareness, a single conscious experience: that
white flame, shooting into the dark, embodying the human spirit, its
fear and its hope... striking at the heart of evil. The silhouette on the
horizon tumbled, and fell. Thousand voices of pure joy rose from the
assembled masses, joined seconds later by a deafening drawn-out thud
from the collapsing monster as if the Earth itself was drawing a sigh of
relief. After centuries of oppression, humanity at last was free from
the cruel tyranny of the dragon.
The joy cry resolved into a jubilating chant: "Long live the king!
Long live us all!" The king's advisors, like everybody that night, were
as happy as children; they embraced each other and congratulated the
king: "We did it! We did it!"
But the king answered in a broken voice: "Yes, we did it, we killed
the dragon today. But damn, why did we start so late? This could have
been done five, maybe ten years ago! Millions of people wouldn't have
had to die."
The king stepped off the platform and walked up to the young man in
handcuffs, who was sitting on the ground. There he fell down on his
knees. "Forgive me! Oh my God, please forgive me!"
The rain started falling, in large, heavy drops, turning the ground
into mud, drenching the king's purple robes, and dissolving the blood on
the young man's face. "I am so very sorry about your father," said the
king.
"It's not your fault," replied the young man. "Do you remember twelve
years ago in the castle? That crying little boy who wanted you to bring
back his grandmother – that was me. I didn't realize then that you
couldn't possibly do what I asked for. Today I wanted you to save my
father. Yet it was impossible to do that now, without jeopardizing the
launch. But you have saved my life, and my mother and my sister. How can
we ever thank you enough for that?"
"Listen to them," said the king, gesturing towards the crowds. "They
are cheering me for what happened tonight. But the hero is you. You
cried out. You rallied us against evil." The king signaled a guard to
come and unlock the handcuffs. "Now, go to your mother and sister. You
and your family shall always be welcome at the court, and anything you
wish for – if it be within my power – shall be granted."
The young man left, and the royal entourage, huddling in the
downpour, accumulated around their monarch who was still kneeling in the
mud. Amongst the fancy couture, which was being increasingly ruined by
the rain, a bunch of powdered faces expressed a superposition of joy,
relief, and discombobulation. So much had changed in the last hour: the
right to an open future had been regained, a primordial fear had been
abolished, and many a long-held assumption had been overturned. Unsure
now about what was required of them in this unfamiliar situation, they
stood there tentatively, as if probing whether the ground would still
hold, exchanging glances, and waiting for some kind of indication.
Finally, the king rose, wiping his hands on the sides of his
pants.
"Your majesty, what do we do now?" ventured the most senior
courtier.
"My dear friends," said the king, "we have come a long way... yet our
journey has only just begun. Our species is young on this planet. Today
we are like children again. The future lies open before us. We shall go
into this future and try to do better than we have done in the past. We
have time now – time to get things right, time to grow up, time to learn
from our mistakes, time for the slow process of building a better world,
and time to get settled in it. Tonight, let all the bells in the kingdom
ring until midnight, in remembrance of our dead forbears, and then after
midnight let us celebrate till the sun comes up. And in the coming days...
I believe we have some reorganization to do!"
MORAL
Stories about aging have traditionally focused on the need for
graceful accommodation. The recommended solution to diminishing vigor
and impending death was resignation coupled with an effort to achieve
closure in practical affairs and personal relationships. Given that
nothing could be done to prevent or retard aging, this focus made sense.
Rather than fretting about the inevitable, one could aim for peace of
mind.
Today we face a different situation. While we still lack effective
and acceptable means for slowing the aging process, we
can identify research directions that might lead to the development of
such means in the foreseeable future. "Deathist" stories and ideologies,
which counsel passive acceptance, are no longer harmless sources of
consolation. They are fatal barriers to urgently needed action.
Many distinguished technologists and scientists tell us that it will
become possible to retard, and eventually to halt and reverse, human
senescence. At present, there is little
agreement about the time-scale or the specific means, nor is there a
consensus that the goal is even achievable in principle. In relation to
the fable (where aging is, of course, represented by the dragon), we are
therefore at a stage somewhere between that at which the lone sage
predicted the dragon's eventual demise and that at which the iconoclast
dragonologists convinced their peers by demonstrating a composite
material that was harder than dragon scales.
The ethical argument that the fable presents is simple: There are
obvious and compelling moral reasons for the people in the fable to get
rid of the dragon. Our situation with regard to human senescence is
closely analogous and ethically isomorphic to the situation of the
people in the fable with regard to the dragon. Therefore, we have
compelling moral reasons to get rid of human senescence.
The argument is not in favor of life-span extension per se.
Adding extra years of sickness and debility at the end of life would be
pointless. The argument is in favor of extending, as far as possible,
the human health-span. By slowing or halting the aging process,
the healthy human life span would be extended. Individuals would be able
to remain healthy, vigorous, and productive at ages at which they would
otherwise be dead.
In addition to this general moral, there are a number of more
specific lessons:
(1) A recurrent tragedy became a fact of life, a
statistic. In the fable, people's expectations adapted to
the existence of the dragon, to the extent that many became unable to
perceive its badness. Aging, too, has become a mere "fact of life" –
despite being the principal cause of an unfathomable amount of human
suffering and death.
(2) A static view of technology. People
reasoned that it would never become possible to kill the dragon because
all attempts had failed in the past. They failed to take into account
accelerated technological progress. Is a similar mistake leading us to
underestimate the chances of a cure for aging?
(3) Administration became its own purpose.
One seventh of the economy went to dragon-administration (which is also
the fraction of its GDP that the U.S. spends on healthcare).
Damage-limitation became such an exclusive focus that it made people
neglect the underlying cause. Instead of a massive publicly-funded
research program to halt aging, we spend almost our entire health budget
on health-care and on researching individual diseases.
(4) The social good became detached from the good for
people. The king's advisors worried about the possible
social problems that could be caused by the anti-dragonists. They said
that no known social good would come from the demise of the dragon.
Ultimately, however, social orders exist for the benefit of people, and
it is generally good for people if their lives are saved.
(5) The lack of a sense of proportion. A
tiger killed a farmer. A rhumba of rattlesnakes plagued a village. The
king got rid of the tiger and the rattlesnakes, and thereby did his
people a service. Yet he was at fault, because he got his priorities
wrong.
(6) Fine phrases and hollow rhetoric. The
king's morality advisor spoke eloquently about human dignity and our
species-specified nature, in phrases lifted, mostly verbatim, from the
advisor's contemporary equivalents. Yet the rhetoric was a
smoke screen that hid rather than revealed moral reality. The boy's
inarticulate but honest testimony, by contrast, points to the central
fact of the case: the dragon is bad; it destroys people. This is also
the basic truth about human senescence.
(7) Failure to appreciate the
urgency. Until very late in the story, nobody fully
realized what was at stake. Only as the king was staring into the
bloodied face of the young pleading man does the extent of the tragedy
sink in. Searching for a cure for aging is not just a nice thing that we
should perhaps one day get around to. It is an urgent, screaming moral
imperative. The sooner we start a focused research program, the sooner
we will get results. It matters if we get the cure in 25 years rather
than in 24 years: a population greater than that of Canada would die as
a result. In this matter, time equals life, at a rate of approximately
70 lives per minute. With the meter ticking at such a furious rate, we
should stop faffing about.
(8) "And in the coming days... I believe we have some
reorganization to do!" The king and his people will face
some major challenges when they recover from their celebration. Their
society has been so conditioned and deformed by the presence of the
dragon that a frightening void now exists. They will have to work
creatively, on both an individual and a societal level, to develop
conditions that will keep lives flourishingly dynamic and meaningful
beyond the accustomed three-score-years-and-ten. Luckily, the human
spirit is good at adapting. Another issue that they may eventually
confront is overpopulation. Maybe people will have to learn to have
children later and less frequently. Maybe they can find ways to sustain
a larger population by using more efficient technology. Maybe they will
one day develop spaceships and begin to colonize the cosmos. We can
leave, for now, the long-lived fable people to grapple with these new
challenges, while we try to make some progress in our own adventure.

Once upon a time, the planet was tyrannized by a giant dragon. The dragon stood taller than the largest cathedral, and it was covered with thick black scales. Its red eyes glowed with hate, and from its terrible jaws flowed an incessant stream of evil-smelling yellowish-green slime. It demanded from humankind a blood-curdling tribute: to satisfy its enormous appetite, ten thousand men and women had to be delivered every evening at the onset of dark to the foot of the mountain where the dragon-tyrant lived. Sometimes the dragon would devour these unfortunate souls upon arrival; sometimes again it would lock them up in the mountain where they would wither away for months or years before eventually being consumed.
The misery inflicted by the dragon-tyrant was incalculable. In addition to the ten thousand who were gruesomely slaughtered each day, there were the mothers, fathers, wives, husbands, children, and friends that were left behind to grieve the loss of their departed loved ones.
Some people tried to fight the dragon, but whether they were brave or foolish was difficult to say. Priests and magicians called down curses, to no avail. Warriors, armed with roaring courage and the best weapons the smiths could produce, attacked it, but were incinerated by its fire before coming close enough to strike. Chemists concocted toxic brews and tricked the dragon into swallowing them, but the only apparent effect was to further stimulate its appetite. The dragon's claws, jaws, and fire were so effective, its scaly armor so impregnable, and its whole nature so robust, as to make it invincible to any human assault.
Seeing that defeating the tyrant was impossible, humans had no choice but to obey its commands and pay the grisly tribute. The fatalities selected were always elders. Although senior people were as vigorous and healthy as the young, and sometimes wiser, the thinking was that they had at least already enjoyed a few decades of life. The wealthy might gain a brief reprieve by bribing the press gangs that came to fetch them; but, by constitutional law, nobody, not even the king himself, could put off their turn indefinitely.
Spiritual men sought to comfort those who were afraid of being eaten by the dragon (which included almost everyone, although many denied it in public) by promising another life after death, a life that would be free from the dragon-scourge. Other orators argued that the dragon has its place in the natural order and a moral right to be fed. They said that it was part of the very meaning of being human to end up in the dragon's stomach. Others still maintained that the dragon was good for the human species because it kept the population size down. To what extent these arguments convinced the worried souls is not known. Most people tried to cope by not thinking about the grim end that awaited them.
For many centuries this desperate state of affairs continued. Nobody kept count any longer of the cumulative death toll, nor of the number of tears shed by the bereft. Expectations had gradually adjusted and the dragon-tyrant had become a fact of life. In view of the evident futility of resistance, attempts to kill the dragon had ceased. Instead, efforts now focused on placating it. While the dragon would occasionally raid the cities, it was found that the punctual delivery to the mountain of its quota of life reduced the frequency of these incursions.
Knowing that their turn to become dragon-fodder was always impending, people began having children earlier and more often. It was not uncommon for a girl to be pregnant by her sixteenth birthday. Couples often spawned a dozen children. The human population was thus kept from shrinking, and the dragon was kept from going hungry.
Over the course of these centuries, the dragon, being well fed, slowly but steadily grew bigger. It had become almost as large as the mountain on which it lived. And its appetite had increased proportionately. Ten thousand human bodies were no longer enough to fill its belly. It now demanded eighty thousand, to be delivered to the foot of the mountain every evening at the onset of dark.
What occupied the king's mind more than the deaths and the dragon itself was the logistics of collecting and transporting so many people to the mountain every day. This was not an easy task.
To facilitate the process, the king had a railway track constructed: two straight lines of glistening steel leading up to the dragon's abode. Every twenty minutes, a train would arrive at the mountain terminal crammed with people, and would return empty. On moonlit nights, the passengers traveling on this train, if there had been windows for them to stick their heads out of, would have been able to see in front of them the double silhouette of the dragon and the mountain, and two glowing red eyes, like the beams from a pair of giant lighthouses, pointing the way to annihilation.
Servants were employed by the king in large numbers to administer the tribute. There were registrars who kept track of whose turn it was to be sent. There were people-collectors who would be dispatched in special carts to fetch the designated people. Often traveling at breakneck speed, they would rush their cargo either to a railway station or directly to the mountain. There were clerks who administered the pensions paid to the decimated families who were no longer able to support themselves. There were comforters who would travel with the doomed on their way to the dragon, trying to ease their anguish with spirits and drugs.
There was, moreover, a cadre of dragonologists who studied how these logistic processes could be made more efficient. Some dragonologists also conducted studies of the dragon's physiology and behavior, and collected samples – its shed scales, the slime that drooled from its jaws, its lost teeth, and its excrements, which were specked with fragments of human bone. All these items were painstakingly annotated and archived. The more the beast was understood, the more the general perception of its invincibility was confirmed. Its black scales, in particular, were harder than any material known to man, and there seemed no way to make as much as a scratch in its armor.
To finance all these activities, the king levied heavy taxes on his people. Dragon-related expenditures, already accounting for one seventh of the economy, were growing even faster than the dragon itself.
Humanity is a curious species. Every once in a while, somebody gets a good idea. Others copy the idea, adding to it their own improvements. Over time, many wondrous tools and systems are developed. Some of these devices – calculators, thermometers, microscopes, and the glass vials that the chemists use to boil and distil liquids – serve to make it easier to generate and try out new ideas, including ideas that expedite the process of idea-generation.
Thus the great wheel of invention, which had turned at an almost imperceptibly slow pace in the older ages, gradually began to accelerate.
Sages predicted that a day would come when technology would enable humans to fly and do many other astonishing things. One of the sages, who was held in high esteem by some of the other sages but whose eccentric manners had made him a social outcast and recluse, went so far as to predict that technology would eventually make it possible to build a contraption that could kill the dragon-tyrant.
The king's scholars, however, dismissed these ideas. They said that humans were far too heavy to fly and in any case lacked feathers. And as for the impossible notion that the dragon-tyrant could be killed, history books recounted hundreds of attempts to do just that, not one of which had been successful. "We all know that this man had some irresponsible ideas," a scholar of letters later wrote in his obituary of the reclusive sage who had by then been sent off to be devoured by the beast whose demise he had foretold, "but his writings were quite entertaining and perhaps we should be grateful to the dragon for making possible the interesting genre of dragon-bashing literature which reveals so much about the culture of angst!"
Meanwhile, the wheel of invention kept turning. Mere decades later, humans did fly and accomplished many other astonishing things.
A few iconoclastic dragonologists began arguing for a new attack on the dragon-tyrant. Killing the dragon would not be easy, they said, but if some material could be invented that was harder than the dragon's armor, and if this material could be fashioned into some kind of projectile, then maybe the feat would be possible. At first, the iconoclasts' ideas were rejected by their dragonologist peers on grounds that no known material was harder than dragon scales. But after working on the problem for many years, one of the iconoclasts succeeded in demonstrating that a dragon scale could be pierced by an object made of a certain composite material. Many dragonologists who had previously been skeptical now joined the iconoclasts. Engineers calculated that a huge projectile could be made of this material and launched with sufficient force to penetrate the dragon's armor. However, the manufacture of the needed quantity of the composite material would be expensive.
A group of several eminent engineers and dragonologists sent a petition to the king asking for funding to build the anti-dragon projectile. At time when the petition was sent, the king was preoccupied with leading his army into war against a tiger. The tiger had killed a farmer and subsequently disappeared into the jungle. There was widespread fear in the countryside that the tiger might come out and strike again. The king had the jungle surrounded and ordered his troops to begin slashing their way through it. At the conclusion of the campaign, the king could announce that all 163 tigers in the jungle, including presumably the murderous one, had been hunted down and killed. During the tumult of the war, however, the petition had been lost or forgotten.
The petitioners therefore sent another appeal. This time they received a reply from one of the king's secretaries saying that the king would consider their request after he was done reviewing the annual dragon-administration budget. This year's budget was the largest to date and included funding for a new railway track to the mountain. A second track was deemed necessary, as the original track could no longer support the increasing traffic. (The tribute demanded by the dragon-tyrant had increased to one hundred thousand human beings, to be delivered to the foot of the mountain every evening at the onset of dark.) When the budget was finally approved, however, reports were coming from a remote part of the country that a village was suffering from a rattlesnake infestation. The king had to leave urgently to mobilize his army and ride off to defeat this new threat. The anti-dragonists' appeal was filed away in a dusty cabinet in the castle basement.
The anti-dragonists met again to decide what was to be done. The debate was animated and continued long into the night. It was almost daybreak when they finally resolved to take the matter to the people. Over the following weeks, they traveled around the country, gave public lectures, and explained their proposal to anyone who would listen. At first, people were skeptical. They had been taught in school that the dragon-tyrant was invincible and that the sacrifices it demanded had to be accepted as a fact of life. Yet when they learnt about the new composite material and about the designs for the projectile, many became intrigued. In increasing numbers, citizens flocked to the anti-dragonist lectures. Activists started organizing public rallies in support of the proposal.
When the king read about these meetings in the newspaper, he summoned his advisors and asked them what they thought about it. They informed him about the petitions that had been sent but told him that the anti-dragonists were troublemakers whose teachings were causing public unrest. It was much better for the social order, they said, that the people accepted the inevitability of the dragon-tyrant tribute. The dragon-administration provided many jobs that would be lost if the dragon was slaughtered. There was no known social good coming from the conquest of the dragon. In any case, the king's coffers were currently nearly empty after the two military campaigns and the funding set aside for the second railway line. The king, who was at the time enjoying great popularity for having vanquished the rattlesnake infestation, listened to his advisors' arguments but worried that he might lose some of his popular support if was seen to ignore the anti-dragonist petition. He therefore decided to hold an open hearing. Leading dragonologists, ministers of the state, and interested members of the public were invited to attend.
The meeting took place on the darkest day of the year, just before the Christmas holidays, in the largest hall of the royal castle. The hall was packed to the last seat and people were crowding in the aisles. The mood was charged with an earnest intensity normally reserved for pivotal wartime sessions.
After the king had welcomed everyone, he gave the floor to the leading scientist behind the anti-dragonist proposal, a woman with a serious, almost stern expression on her face. She proceeded to explain in clear language how the proposed device would work and how the requisite amount of the composite material could be manufactured. Given the requested amount of funding, it should be possible to complete the work in fifteen to twenty years. With an even greater amount of funding, it might be possible to do it in as little as twelve years. However, there could be no absolute guarantee that it would work. The crowd followed her presentation intently.
Next to speak was the king's chief advisor for morality, a man with a booming voice that easily filled the auditorium:
"Let us grant that this woman is correct about the science and that the project is technologically possible, although I don't think that has actually been proven. Now she desires that we get rid of the dragon. Presumably, she thinks she's got the right not to be chewed up by the dragon. How willful and presumptuous. The finitude of human life is a blessing for every individual, whether he knows it or not. Getting rid of the dragon, which might seem like such a convenient thing to do, would undermine our human dignity. The preoccupation with killing the dragon will deflect us from realizing more fully the aspirations to which our lives naturally point, from living well rather than merely staying alive. It is debasing, yes debasing, for a person to want to continue his or her mediocre life for as long as possible without worrying about some of the higher questions about what life is to be used for. But I tell you, the nature of the dragon is to eat humans, and our own species-specified nature is truly and nobly fulfilled only by getting eaten by it..."
The audience listened respectfully to this highly decorated speaker. The phrases were so eloquent that it was hard to resist the feeling that some deep thoughts must lurk behind them, although nobody could quite grasp what they were. Surely, words coming from such a distinguished appointee of the king must have profound substance.
The speaker next in line was a spiritual sage who was widely respected for his kindness and gentleness as well as for his devotion. As he strode to the podium, a small boy yelled out from the audience: "The dragon is bad!"
The boy's parents turned bright red and began hushing and scolding the child. But the sage said, "Let the boy speak. He is probably wiser than an old fool like me."
At first, the boy was too scared and confused to move. But when he saw the genuinely friendly smile on the sage's face and the outreached hand, he obediently took it and followed the sage up to the podium. "Now, there's a brave little man," said the sage. "Are you afraid of the dragon?"
"I want my granny back," said the boy.
"Did the dragon take your granny away?"
"Yes," the boy said, tears welling up in his large frightened eyes. "Granny promised that she would teach me how to bake gingerbread cookies for Christmas. She said that we would make a little house out of gingerbread and little gingerbread men that would live in it. Then those people in white clothes came and took Granny away to the dragon... The dragon is bad and it eats people... I want my Granny back!"
At this point the child was crying so hard that the sage had to return him to his parents.
There were several other speakers that evening, but the child's simple testimony had punctured the rhetorical balloon that the king's ministers had tried to inflate. The people were backing the anti-dragonists, and by the end of the evening even the king had come to recognize the reason and the humanity of their cause. In his closing statement, he simply said: "Let's do it!"
As the news spread, celebrations erupted in the streets. Those who had been campaigning for the anti-dragonists toasted each other and drank to the future of humanity.
The next morning, a billion people woke up and realized that their turn to be sent to the dragon would come before the projectile would be completed. A tipping point was reached. Whereas before, active support for the anti-dragonist cause had been limited to a small group of visionaries, it now became the number one priority and concern on everybody's mind. The abstract notion of "the general will" took on an almost tangible intensity and concreteness. Mass rallies raised money for the projectile project and urged the king to increase the level of state support. The king responded to these appeals. In his New Year address, he announced that he would pass an extra appropriations bill to support the project at a high level of funding; additionally, he would sell off his summer castle and some of his land and make a large personal donation. "I believe that this nation should commit itself to achieving the goal, before this decade is out, of freeing the world from the ancient scourge of the dragon-tyrant."
Thus started a great technological race against time. The concept of an anti-dragon projectile was simple, but to make it a reality required solutions to a thousand smaller technical problems, each of which required dozens of time-consuming steps and missteps. Test-missiles were fired but fell dead to the ground or flew off in the wrong direction. In one tragic accident, a wayward missile landed on a hospital and killed several hundred patients and staff. But there was now a real seriousness of purpose, and the tests continued even as the corpses were being dug out from the debris.
Despite almost unlimited funding and round-the-clock work by the technicians, the king's deadline could not be met. The decade concluded and the dragon was still alive and well. But the effort was getting closer. A prototype missile had been successfully test fired. Production of the core, made of the expensive composite material, was on schedule for its completion to coincide with the finishing of the fully tested and debugged missile shell into which it was to be loaded. The launch date was set to the following year's New Year's Eve, exactly twelve years after the project's official inauguration. The best-selling Christmas gift that year was a calendar that counted down the days to time zero, the proceeds going to the projectile project.
The king had undergone a personal transformation from his earlier frivolous and thoughtless self. He now spent as much time as he could in the laboratories and the manufacturing plants, encouraging the workers and praising their toil. Sometimes he would bring a sleeping bag and spend the night on a noisy machine floor. He even studied and tried to understand the technical aspects of their work. Yet he confined himself to giving moral support and refrained from meddling in technical and managerial matters.
Seven days before New Year, the woman who had made the case for the project almost twelve years earlier, and was now its chief executive, came to the royal castle and requested an urgent audience with the king. When the king got her note, he excused himself to the foreign dignitaries whom he was reluctantly entertaining at the annual Christmas dinner and hurried off to the private room where the scientist was waiting. As always of late, she looked pale and worn from her long working hours. This evening, however, the king also thought he could detect a ray of relief and satisfaction in her eyes.
She told him that the missile had been deployed, the core had been loaded, everything had been triple-checked, they were ready to launch, and would the king give his final go-ahead. The king sank down in an armchair and closed his eyes. He was thinking hard. By launching the projectile tonight, one week early, seven hundred thousand people would be saved. Yet if something went wrong, if it missed its target and hit the mountain instead, it would be a disaster. A new core would have to be constructed from scratch and the project would be set back by some four years. He sat there, silently, for almost an hour. Just as the scientist had become convinced that he had fallen asleep, he opened his eyes and said in a firm voice: "No. I want you to go right back to the lab. I want you to check and then re-check everything again." The scientist could not help a sigh escaping her; but she nodded and left.
The last day of the year was cold and overcast, but there was no wind, which meant good launch conditions. The sun was setting. Technicians were scuttling around making the final adjustments and giving everything one last check. The king and his closest advisors were observing from a platform close to the launch pad. Further away, behind a fence, large numbers of the public had assembled to witness the great event. A large clock was showing the countdown: fifty minutes to go.
An advisor tapped the king on the shoulder and drew his attention to the fence. There was some tumult. Somebody had apparently jumped the fence and was running towards the platform where the king sat. Security quickly caught up with him. He was handcuffed and taken away. The king turned his attention back to the launch pad, and to the mountain in the background. In front of it, he could see the dark slumped profile of the dragon. It was eating.
Some twenty minutes later, the king was surprised to see the handcuffed man reappearing a short distance from the platform. His nose was bleeding and he was accompanied by two security guards. The man appeared to be in a frenzied state. When he spotted the king, he began shouting at the top of his lungs: "The last train! The last train! Stop the last train!"
"Who is this young man?" said the king. "His face seems familiar, but I cannot quite place him. What does he want? Let him come up."
The young man was a junior clerk in the ministry of transportation, and the reason for his frenzy was that he had discovered that his father was on the last train to the mountain. The king had ordered the train traffic to continue, fearing that any disruption might cause the dragon to stir and leave the open field in front of the mountain where it now spent most of its time. The young man begged the king to issue a recall-order for the last train, which was due to arrive at the mountain terminal five minutes before time zero.
"I cannot do it," said the king, "I cannot take the risk."
"But the trains frequently run five minutes late. The dragon won't notice! Please!"
The young man was kneeling before the king, imploring him to save his father's life and the lives of the other thousand passengers onboard that last train.
The king looked down at the pleading, bloodied face of the young man. But he bit his lip, and shook his head. The young man continued to wail even as the guards carried him off the platform: "Please! Stop the last train! Please!"
The king stood silent and motionless, until, after while, the wailing suddenly ceased. The king looked up and glanced over at the countdown clock: five minutes remaining.
Four minutes. Three minutes. Two minutes.
The last technician left the launch pad.
30 seconds. 20 seconds. Ten, nine, eight...
As a ball of fire enveloped the launch pad and the missile shot out, the spectators instinctively rose to the tips of their toes, and all eyes fixated at the front end of the white flame from the rocket's afterburners heading towards the distant mountain. The masses, the king, the low and the high, the young and the old, it was as if at this moment they shared a single awareness, a single conscious experience: that white flame, shooting into the dark, embodying the human spirit, its fear and its hope... striking at the heart of evil. The silhouette on the horizon tumbled, and fell. Thousand voices of pure joy rose from the assembled masses, joined seconds later by a deafening drawn-out thud from the collapsing monster as if the Earth itself was drawing a sigh of relief. After centuries of oppression, humanity at last was free from the cruel tyranny of the dragon.
The joy cry resolved into a jubilating chant: "Long live the king! Long live us all!" The king's advisors, like everybody that night, were as happy as children; they embraced each other and congratulated the king: "We did it! We did it!"
But the king answered in a broken voice: "Yes, we did it, we killed the dragon today. But damn, why did we start so late? This could have been done five, maybe ten years ago! Millions of people wouldn't have had to die."
The king stepped off the platform and walked up to the young man in handcuffs, who was sitting on the ground. There he fell down on his knees. "Forgive me! Oh my God, please forgive me!"
The rain started falling, in large, heavy drops, turning the ground into mud, drenching the king's purple robes, and dissolving the blood on the young man's face. "I am so very sorry about your father," said the king.
"It's not your fault," replied the young man. "Do you remember twelve years ago in the castle? That crying little boy who wanted you to bring back his grandmother – that was me. I didn't realize then that you couldn't possibly do what I asked for. Today I wanted you to save my father. Yet it was impossible to do that now, without jeopardizing the launch. But you have saved my life, and my mother and my sister. How can we ever thank you enough for that?"
"Listen to them," said the king, gesturing towards the crowds. "They are cheering me for what happened tonight. But the hero is you. You cried out. You rallied us against evil." The king signaled a guard to come and unlock the handcuffs. "Now, go to your mother and sister. You and your family shall always be welcome at the court, and anything you wish for – if it be within my power – shall be granted."
The young man left, and the royal entourage, huddling in the downpour, accumulated around their monarch who was still kneeling in the mud. Amongst the fancy couture, which was being increasingly ruined by the rain, a bunch of powdered faces expressed a superposition of joy, relief, and discombobulation. So much had changed in the last hour: the right to an open future had been regained, a primordial fear had been abolished, and many a long-held assumption had been overturned. Unsure now about what was required of them in this unfamiliar situation, they stood there tentatively, as if probing whether the ground would still hold, exchanging glances, and waiting for some kind of indication.
Finally, the king rose, wiping his hands on the sides of his pants.
"Your majesty, what do we do now?" ventured the most senior courtier.
"My dear friends," said the king, "we have come a long way... yet our journey has only just begun. Our species is young on this planet. Today we are like children again. The future lies open before us. We shall go into this future and try to do better than we have done in the past. We have time now – time to get things right, time to grow up, time to learn from our mistakes, time for the slow process of building a better world, and time to get settled in it. Tonight, let all the bells in the kingdom ring until midnight, in remembrance of our dead forbears, and then after midnight let us celebrate till the sun comes up. And in the coming days... I believe we have some reorganization to do!"
MORAL
Stories about aging have traditionally focused on the need for graceful accommodation. The recommended solution to diminishing vigor and impending death was resignation coupled with an effort to achieve closure in practical affairs and personal relationships. Given that nothing could be done to prevent or retard aging, this focus made sense. Rather than fretting about the inevitable, one could aim for peace of mind.
Today we face a different situation. While we still lack effective and acceptable means for slowing the aging process1, we can identify research directions that might lead to the development of such means in the foreseeable future. "Deathist" stories and ideologies, which counsel passive acceptance, are no longer harmless sources of consolation. They are fatal barriers to urgently needed action.
Many distinguished technologists and scientists tell us that it will become possible to retard, and eventually to halt and reverse, human senescence.2 At present, there is little agreement about the time-scale or the specific means, nor is there a consensus that the goal is even achievable in principle. In relation to the fable (where aging is, of course, represented by the dragon), we are therefore at a stage somewhere between that at which the lone sage predicted the dragon's eventual demise and that at which the iconoclast dragonologists convinced their peers by demonstrating a composite material that was harder than dragon scales.
The ethical argument that the fable presents is simple: There are obvious and compelling moral reasons for the people in the fable to get rid of the dragon. Our situation with regard to human senescence is closely analogous and ethically isomorphic to the situation of the people in the fable with regard to the dragon. Therefore, we have compelling moral reasons to get rid of human senescence.
The argument is not in favor of life-span extension per se. Adding extra years of sickness and debility at the end of life would be pointless. The argument is in favor of extending, as far as possible, the human health-span. By slowing or halting the aging process, the healthy human life span would be extended. Individuals would be able to remain healthy, vigorous, and productive at ages at which they would otherwise be dead.
In addition to this general moral, there are a number of more specific lessons:
(1) A recurrent tragedy became a fact of life, a statistic. In the fable, people's expectations adapted to the existence of the dragon, to the extent that many became unable to perceive its badness. Aging, too, has become a mere "fact of life" – despite being the principal cause of an unfathomable amount of human suffering and death.
(2) A static view of technology. People reasoned that it would never become possible to kill the dragon because all attempts had failed in the past. They failed to take into account accelerated technological progress. Is a similar mistake leading us to underestimate the chances of a cure for aging?
(3) Administration became its own purpose. One seventh of the economy went to dragon-administration (which is also the fraction of its GDP that the U.S. spends on healthcare). Damage-limitation became such an exclusive focus that it made people neglect the underlying cause. Instead of a massive publicly-funded research program to halt aging, we spend almost our entire health budget on health-care and on researching individual diseases.
(4) The social good became detached from the good for people. The king's advisors worried about the possible social problems that could be caused by the anti-dragonists. They said that no known social good would come from the demise of the dragon. Ultimately, however, social orders exist for the benefit of people, and it is generally good for people if their lives are saved.
(5) The lack of a sense of proportion. A tiger killed a farmer. A rhumba of rattlesnakes plagued a village. The king got rid of the tiger and the rattlesnakes, and thereby did his people a service. Yet he was at fault, because he got his priorities wrong.
(6) Fine phrases and hollow rhetoric. The king's morality advisor spoke eloquently about human dignity and our species-specified nature, in phrases lifted, mostly verbatim, from the advisor's contemporary equivalents.3 Yet the rhetoric was a smoke screen that hid rather than revealed moral reality. The boy's inarticulate but honest testimony, by contrast, points to the central fact of the case: the dragon is bad; it destroys people. This is also the basic truth about human senescence.
(7) Failure to appreciate the urgency. Until very late in the story, nobody fully realized what was at stake. Only as the king was staring into the bloodied face of the young pleading man does the extent of the tragedy sink in. Searching for a cure for aging is not just a nice thing that we should perhaps one day get around to. It is an urgent, screaming moral imperative. The sooner we start a focused research program, the sooner we will get results. It matters if we get the cure in 25 years rather than in 24 years: a population greater than that of Canada would die as a result. In this matter, time equals life, at a rate of approximately 70 lives per minute. With the meter ticking at such a furious rate, we should stop faffing about.
(8) "And in the coming days... I believe we have some reorganization to do!" The king and his people will face some major challenges when they recover from their celebration. Their society has been so conditioned and deformed by the presence of the dragon that a frightening void now exists. They will have to work creatively, on both an individual and a societal level, to develop conditions that will keep lives flourishingly dynamic and meaningful beyond the accustomed three-score-years-and-ten. Luckily, the human spirit is good at adapting. Another issue that they may eventually confront is overpopulation. Maybe people will have to learn to have children later and less frequently. Maybe they can find ways to sustain a larger population by using more efficient technology. Maybe they will one day develop spaceships and begin to colonize the cosmos. We can leave, for now, the long-lived fable people to grapple with these new challenges, while we try to make some progress in our own adventure.4
Calorie restriction (a diet low in calories but high in nutrients) extends maximal lifespan and delays the onset of age-related illnesses in all species that have been tested. Preliminary results from an ongoing study on rhesus and squirrel monkeys show similar effects. It seems quite likely that calorie restriction would work for our species too. Few humans, however, would be willing to put themselves through a lifelong hunger-diet. Some researchers are searching for calorie-restriction mimetics – compounds that elicit the desirable effects of lowered caloric intake without us having to go hungry. (See e.g. Lane, M. et al. (1999) "Nutritional modulation of aging in nonhuman primates," J. Nutr. Health & Aging, 3(2): 69-76.)↩︎
