Mining Asteroids: Planetary Resources Announces Their Plans



Last week, a press release from big names like Larry Page, Ross Perot and James Cameron about combining space exploration with resource extraction made it all but obvious that somebody was going to announce some very ambitious plans surrounding asteroid mining. Now, Planetary Resources has officially unveiled its plans.

The plan will focus on two things: precious metals and water. Materials such as platinum and rare earth elements are crucial to electronics, increasingly scarce on Earth and abundant in space. Planetary Resources thinks it can find enough of the stuff in asteroids to offset the massive cost of getting to it. According to the press release:

A single 500-meter platinum-rich asteroid contains the equivalent of all the Platinum Group Metals mined in history. “Many of the scarce metals and minerals on Earth are in near-infinite quantities in space. As access to these materials increases, not only will the cost of everything from microelectronics to energy storage be reduced, but new applications for these abundant elements will result in important and novel applications,” said Peter H. Diamandis, M.D., Co-Founder and Co-Chairman, Planetary Resources, Inc.

But water may be the most valuable resource asteroids have to offer. Planetary Resources plans to use near-earth asteroids as stepping stones to exploring the rest of the solar system by using their water to both support life and propel rockets.

With the still-nascent world of space tourism also, it’s clear that we’re entering into a new era of privately-driven space exploration. For the tech luminaries on board, this industry shows the same kind of limitless promise that Silicon Valley did a few years ago.

“I see the same potential in Planetary Resources as I did in the early days of Google,” said Ram Shriram, founder of Shirpalo and Google board member.

“The promise of Planetary Resources is to apply commercial innovation to space exploration. They are developing cost-effective, production-line spacecraft that will visit near-Earth asteroids in rapid succession, increasing our scientific knowledge of these bodies and enabling the economic development of the resources they contain,” said Tom Jones, Ph.D., a veteran NASA astronaut and advisor to Planetary Resources.

The Greatest Films of All Time

By Roger Ebert 



I am faced once again with the task of voting in Sight & Sound magazine's famous poll to determine the greatest films of all time. Apart from my annual year's best lists, this is the only list I vote in. It is a challenge. After voting in 1972, 1982 and 1992, I came up with these ten titles in 2002:
Aguirre, Wrath of God (Herzog) Apocalypse Now (Coppola) Citizen Kane (Welles) Dekalog (Kieslowski) La Dolce Vita (Fellini) The General (Keaton) Raging Bull (Scorsese) 2001: A Space Odyssey (Kubrick) Tokyo Story (Ozu) Vertigo (Hitchcock)

To add a title, I must remove one. Which film can I do without? Not a single one. One of my shifts last time was to replace Hitchcock's "Notorious" with "Vertigo," because after going through both a shot at a time during various campus sessions, I decided that "Vertigo" was, after all, the better of two nearly perfect films.

The other titles I consider the best work by their directors. I expect Coppola's "The Godfather" to be on this year's S&S list again, and it may even move higher. It is a great film. But "Apocalypse Now" is a film which still causes real, not figurative, chills to run along my spine, and it is certainly the bravest and most ambitious fruit of Coppola's genius.

I've written before how its critical reputation was harmed after he made an unwise statement at the Cannes premiere about being dissatisfied with the ending. I was there the night he said it, on a yacht while chatting with six or seven film critics. It was clear the film was a triumph. It was clear he was referring to the fact that the film's 70mm version was intended to play without end titles, which would be supplied by a brochure. The 35mm ending was as we see it now. That's all he meant. An urban legend has somehow perpetuated itself that he was referring to the entire Kurtz segment.

More critics would say "8 1/2" was Fellini's greatest work, and there is support for "Amarcord" and "La Strada." Sometimes the way you consider a film depends on when and why you saw it, and what it meant to you at that time. "La Dolce Vita" has become a touchstone in my life: A film about a kind of life I dreamed of living, then a film about the life I was living, the about my escape from that life. Now, half a century after its release, it is about the arc of my life, and its closing scene is an eerie reflection of my wordlessness and difficulty in communicating. I still yearn and dream, but it is so hard for me to communicate that--not literally, but figuratively. So the Fellini stays.

So does the Keaton. There must be a silent film, and I consider "The General" to be his best. "Aguirre" is the most evocative expression of Herzog's genius, and I admire it even more after watching him go through it a shot at a time with Ramin Bahrani a few years ago at Boulder. (Having agreed to do one of his films, it was the one he chose.)

"Citizen Kane" speaks for itself. "2001: A Space Odyssey" is likewise a stand-along monument, a great visionary leap, unsurpassed in its vision of man and the universe. It was a statement that came at a time which now looks something like the peak of humanity's technological optimism. Many would choose "Taxi Driver" as Scorsese's greatest film, but I believe "Raging Bull" is his best and most personal, a film he says in some ways saved his life. It is the greatest cinematic expression of the torture of jealousy--his "Othello."

There must be an Ozu. It could be one of several. All of his films are universal. The older I grow and the more I observe how age affects our relationships, the more I think "Tokyo Story" has to teach us. Kurosawa's "Ikiru" has as much to say, but in the rigid economy of the Sight & Sound limitations, impossible choices are forced.

That leaves only one title to be replaced: "Dekalog," by Kieslowski. This is an easy decision, because the magazine's new rules insist that if you vote for, say, a pair of films ("The Godfather" and "The Godfather Two"), or a trilogy (Ray's "Apu" trilogy or Kieslowski's "Blue, White and Red trilogy), each film counts as a separate title. Therefore, since "Dekalog" consists of ten films, averaging an hour long, it would take all ten places on my list.

At one point in pondering this list, here's what I thought I would do: I would simply start all over with ten new films. Once any film has ever appeared on my S&S list, I consider it canonized. "Notorious" or "The Gates of Heaven," for example, are still two of the ten best films of all time, no matter what a subsequent list says.

I decided not to do that--trash the 2002 list and start again. It was too much like a stunt. Lists are ridiculous, but if you're going to vote, you have to play the game. Besides, the thought of starting with a blank page and a list of all the films ever made fills me with despair.

So there must be one new film.

The two candidates, for me, are Charlie Kaufman's "Synecdoche, New York" (2008) and Terrene Malick's "The Tree of Life" (2011). Like the Herzog, the Kubrick and the Coppola, they are films of almost foolhardy ambition. Like many of the films on my list, they were directed by the artist who wrote them. Like several of them, it attempts no less than to tell the story of an entire life,

In "Synecdoche," Kaufman does this with one of the most audacious sets ever constructed: An ever-expanding series of boxes or compartments within which the protagonist attempts to deal with the categories of his life. The film has the insight that we all deal with life in separate segments, defined by choice or compulsion, desire or fear, past or present. It is no less than a film about life.

In "The Tree of Life," Malick boldly begins with the Big Bang and ends in an unspecified state of attenuated consciousness after death. The central section is the story of birth and raising a family.

I could choose either film. I will choose "The Tree of Life" because it is more affirmative and hopeful. I realize that isn't a defensible reasons for choosing one film over the other, but it is my reason, and making this list is essentially impossible, anyway.

Apart from any other motive for putting a movie title on a list like this, there is always the motive of propaganda: Critics add a title hoping to draw attention to it, and encourage others to see it. For 2012, I suppose this is my propaganda title. I believe it's an important film, and will only increase in stature over the years.



Aguirre, Wrath of God (Herzog)
Apocalypse Now (Coppola)
Citizen Kane (Welles)
La Dolce Vita (Fellini)
The General (Keaton)
Raging Bull (Scorsese)
2001: A Space Odyssey (Kubrick)
Tokyo Story (Ozu)
The Tree of Life (Malick)
Vertigo (Hitchcock)

Your Stupid Stick Figure Family

Putting a  decal with stick figures representing the family members (Mom, Dad, kids, pets) has become an annoying popular thing in US recently....



You usually see them on SUVs or other "family" cars.  Well, people who think this is idiotic started having some fun with the idea.  Here are some of the best examples....

Global Plastic Surgery Analysis



Who has the most plastic surgery?

HAVING cosmetic surgery to enhance what nature gave you (or to keep her at bay) is increasingly common.

In 2010 over 3.3m procedures were done in America, more than anywhere else, according to the International Society of Aesthetic Plastic Surgery.

These were split roughly evenly between "non-invasive" treatments, such as botox or facial peels, and "invasive" surgery. Chin implants ("chinplants") alone rose by 71% on the previous year. But when population is accounted for, South Korea tops the list.

 A 2009 survey by Trend Monitor, a market-research firm, suggested that one in five women in Seoul had gone under the knife.

Beauty is beheld differently in different countries, and this is reflected in the demands made on surgeons' scalpels.

There are seven times more buttock operations in Brazil than the top-25 country average, and five times more vaginal rejuvenations.

In Greece, penis enlargements are performed ten times more often than the average !

Xchange: Obsolete Technology Into Beautiful Art


When was the last time you saw a floppy disk in use? Nick Gentry makes gorgeous portraits from outdated technology with his social art project that turns form and function inside out.

While floppy disks were mostly regarded for the information they stored, the British artist turns the tables and has us examine their aesthetics instead. Gentry's work reflects on the quick pace of technology and how easily we forget what is deemed no longer useful. This idea made us think of Marshall McLuhan's 1969 interview with Playboy, where the tech-obsessed author stated, "My work is designed for the pragmatic purpose of trying to understand our technological environment and its psychic and social consequences."

There might be a dark undertone to Gentry's works...  But it is also a very original way to link art & technology !

Poetry Wednesday: MY GOD, IT'S FULL OF STARS

MY GOD, IT'S FULL OF STARS
by  Tracy K. Smith



         1.

We like to think of it as parallel to what we know,
Only bigger. One man against the authorities.
Or one man against a city of zombies. One man

Who is not, in fact, a man, sent to understand
The caravan of men now chasing him like red ants
Let loose down the pants of America. Man on the run.

Man with a ship to catch, a payload to drop,
This message going out to all of space.... Though
Maybe it's more like life below the sea: silent,

Buoyant, bizarrely benign. Relics
Of an outmoded design. Some like to imagine
A cosmic mother watching through a spray of stars,

Mouthing yes, yes as we toddle toward the light,
Biting her lip if we teeter at some ledge. Longing
To sweep us to her breast, she hopes for the best

While the father storms through adjacent rooms
Ranting with the force of Kingdom Come,
Not caring anymore what might snap us in its jaw.

Sometimes, what I see is a library in a rural community.
All the tall shelves in the big open room. And the pencils
In a cup at Circulation, gnawed on by the entire population.

The books have lived here all along, belonging
For weeks at a time to one or another in the brief sequence
Of family names, speaking (at night mostly) to a face,

A pair of eyes. The most remarkable lies.


         2.

Charlton Heston is waiting to be let in. He asked once politely.
A second time with force from the diaphragm. The third time,
He did it like Moses: arms raised high, face an apocryphal white.

Shirt crisp, suit trim, he stoops a little coming in,
Then grows tall. He scans the room. He stands until I gesture,
Then he sits. Birds commence their evening chatter. Someone fires

Charcoals out below. He'll take a whiskey if I have it. Water if I don't.
I ask him to start from the beginning, but he goes only halfway back.
That was the future once, he says. Before the world went upside down.

Hero, survivor, God's right hand man, I know he sees the blank
Surface of the moon where I see a language built from brick and bone.
He sits straight in his seat, takes a long, slow high-thespian breath,

Then lets it go. For all I know, I was the last true man on this earth. And:
May I smoke? The voices outside soften. Planes jet past heading off or back.
Someone cries that she does not want to go to bed. Footsteps overhead.

A fountain in the neighbor's yard babbles to itself, and the night air
Lifts the sound indoors. It was another time, he says, picking up again.
We were pioneers. Will you fight to stay alive here, riding the earth

Toward God-knows-where? I think of Atlantis buried under ice, gone
One day from sight, the shore from which it rose now glacial and stark.
Our eyes adjust to the dark.


         3.

Perhaps the great error is believing we're alone,
That the others have come and gone-a momentary blip-
When all along, space might be chock-full of traffic,
Bursting at the seams with energy we neither feel
Nor see, flush against us, living, dying, deciding,
Setting solid feet down on planets everywhere,
Bowing to the great stars that command, pitching stones
At whatever are their moons. They live wondering
If they are the only ones, knowing only the wish to know,
And the great black distance they-we-flicker in.

Maybe the dead know, their eyes widening at last,
Seeing the high beams of a million galaxies flick on
At twilight. Hearing the engines flare, the horns
Not letting up, the frenzy of being. I want it to be
One notch below bedlam, like a radio without a dial.
Wide open, so everything floods in at once.
And sealed tight, so nothing escapes. Not even time,
Which should curl in on itself and loop around like smoke.
So that I might be sitting now beside my father
As he raises a lit match to the bowl of his pipe
For the first time in the winter of 1959.


         4.

In those last scenes of Kubrick's "2001"
When Dave is whisked into the center of space,
Which unfurls in an aurora of orgasmic light
Before opening wide, like a jungle orchid
For a love-struck bee, then goes liquid,
Paint in water, and then gauze wafting out and off,
Before, finally, the night-tide, luminescent
And vague, swirls in, and on and on....

In those last scenes, as he floats
Above Jupiter's vast canyons and seas,
Over the lava strewn plains and mountains
Packed in ice, that whole time, he doesn't blink.
In his little ship, blind to what he rides, whisked
Across the wide screen of unparcelled time,
Who knows what blazes through his mind?
Is it still his life he moves through, or does
That end at the end of what he can name?

On the set, it's shot after shot till Kubrick is happy,
Then the costumes go back on their racks
And the great gleaming set goes black.


         5.

When my father worked on the Hubble Telescope, he said
They operated like surgeons: scrubbed and sheathed
In papery green, the room a clean cold, and bright white.

He'd read Larry Niven at home, and drink scotch on the rocks,
His eyes exhausted and pink. These were the Reagan years,
When we lived with our finger on The Button and struggled

To view our enemies as children. My father spent whole seasons
Bowing before the oracle-eye, hungry for what it would find.
His face lit up whenever anyone asked, and his arms would rise

As if he were weightless, perfectly at ease in the never-ending
Night of space. On the ground, we tied postcards to balloons
For peace. Prince Charles married Lady Di. Rock Hudson died.

We learned new words for things. The decade changed.

The first few pictures came back blurred, and I felt ashamed
For all the cheerful engineers, my father and his tribe. The second time,
The optics jibed. We saw to the edge of all there is-

So brutal and alive it seemed to comprehend us back.

The Flight From Conversation

by SHERRY TURKLE, NY Times



We live in a technological universe in which we are always communicating. And yet we have sacrificed conversation for mere connection.

At home, families sit together, texting and reading e-mail. At work executives text during board meetings. We text (and shop and go on Facebook) during classes and when we’re on dates. My students tell me about an important new skill: it involves maintaining eye contact with someone while you text someone else; it’s hard, but it can be done.

Over the past 15 years, I’ve studied technologies of mobile connection and talked to hundreds of people of all ages and circumstances about their plugged-in lives. I’ve learned that the little devices most of us carry around are so powerful that they change not only what we do, but also who we are.

We’ve become accustomed to a new way of being “alone together.” Technology-enabled, we are able to be with one another, and also elsewhere, connected to wherever we want to be. We want to customize our lives. We want to move in and out of where we are because the thing we value most is control over where we focus our attention. We have gotten used to the idea of being in a tribe of one, loyal to our own party.

Our colleagues want to go to that board meeting but pay attention only to what interests them. To some this seems like a good idea, but we can end up hiding from one another, even as we are constantly connected to one another.

A businessman laments that he no longer has colleagues at work. He doesn’t stop by to talk; he doesn’t call. He says that he doesn’t want to interrupt them. He says they’re “too busy on their e-mail.” But then he pauses and corrects himself. “I’m not telling the truth. I’m the one who doesn’t want to be interrupted. I think I should. But I’d rather just do things on my BlackBerry.”

A 16-year-old boy who relies on texting for almost everything says almost wistfully, “Someday, someday, but certainly not now, I’d like to learn how to have a conversation.”

In today’s workplace, young people who have grown up fearing conversation show up on the job wearing earphones. Walking through a college library or the campus of a high-tech start-up, one sees the same thing: we are together, but each of us is in our own bubble, furiously connected to keyboards and tiny touch screens. A senior partner at a Boston law firm describes a scene in his office. Young associates lay out their suite of technologies: laptops, iPods and multiple phones. And then they put their earphones on. “Big ones. Like pilots. They turn their desks into cockpits.” With the young lawyers in their cockpits, the office is quiet, a quiet that does not ask to be broken.

In the silence of connection, people are comforted by being in touch with a lot of people — carefully kept at bay. We can’t get enough of one another if we can use technology to keep one another at distances we can control: not too close, not too far, just right. I think of it as a Goldilocks effect.

Texting and e-mail and posting let us present the self we want to be. This means we can edit. And if we wish to, we can delete. Or retouch: the voice, the flesh, the face, the body. Not too much, not too little — just right.

Human relationships are rich; they’re messy and demanding. We have learned the habit of cleaning them up with technology. And the move from conversation to connection is part of this. But it’s a process in which we shortchange ourselves. Worse, it seems that over time we stop caring, we forget that there is a difference.

We are tempted to think that our little “sips” of online connection add up to a big gulp of real conversation. But they don’t. E-mail, Twitter, Facebook, all of these have their places — in politics, commerce, romance and friendship. But no matter how valuable, they do not substitute for conversation.

Connecting in sips may work for gathering discrete bits of information or for saying, “I am thinking about you.” Or even for saying, “I love you.” But connecting in sips doesn’t work as well when it comes to understanding and knowing one another. In conversation we tend to one another. (The word itself is kinetic; it’s derived from words that mean to move, together.) We can attend to tone and nuance. In conversation, we are called upon to see things from another’s point of view.

FACE-TO-FACE conversation unfolds slowly. It teaches patience. When we communicate on our digital devices, we learn different habits. As we ramp up the volume and velocity of online connections, we start to expect faster answers. To get these, we ask one another simpler questions; we dumb down our communications, even on the most important matters. It is as though we have all put ourselves on cable news. Shakespeare might have said, “We are consum’d with that which we were nourish’d by.”

And we use conversation with others to learn to converse with ourselves. So our flight from conversation can mean diminished chances to learn skills of self-reflection. These days, social media continually asks us what’s “on our mind,” but we have little motivation to say something truly self-reflective. Self-reflection in conversation requires trust. It’s hard to do anything with 3,000 Facebook friends except connect.

As we get used to being shortchanged on conversation and to getting by with less, we seem almost willing to dispense with people altogether. Serious people muse about the future of computer programs as psychiatrists. A high school sophomore confides to me that he wishes he could talk to an artificial intelligence program instead of his dad about dating; he says the A.I. would have so much more in its database. Indeed, many people tell me they hope that as Siri, the digital assistant on Apple’s iPhone, becomes more advanced, “she” will be more and more like a best friend — one who will listen when others won’t.

During the years I have spent researching people and their relationships with technology, I have often heard the sentiment “No one is listening to me.” I believe this feeling helps explain why it is so appealing to have a Facebook page or a Twitter feed — each provides so many automatic listeners. And it helps explain why — against all reason — so many of us are willing to talk to machines that seem to care about us. Researchers around the world are busy inventing sociable robots, designed to be companions to the elderly, to children, to all of us.

One of the most haunting experiences during my research came when I brought one of these robots, designed in the shape of a baby seal, to an elder-care facility, and an older woman began to talk to it about the loss of her child. The robot seemed to be looking into her eyes. It seemed to be following the conversation. The woman was comforted.

And so many people found this amazing. Like the sophomore who wants advice about dating from artificial intelligence and those who look forward to computer psychiatry, this enthusiasm speaks to how much we have confused conversation with connection and collectively seem to have embraced a new kind of delusion that accepts the simulation of compassion as sufficient unto the day. And why would we want to talk about love and loss with a machine that has no experience of the arc of human life? Have we so lost confidence that we will be there for one another?

WE expect more from technology and less from one another and seem increasingly drawn to technologies that provide the illusion of companionship without the demands of relationship. Always-on/always-on-you devices provide three powerful fantasies: that we will always be heard; that we can put our attention wherever we want it to be; and that we never have to be alone. Indeed our new devices have turned being alone into a problem that can be solved.

When people are alone, even for a few moments, they fidget and reach for a device. Here connection works like a symptom, not a cure, and our constant, reflexive impulse to connect shapes a new way of being.

Think of it as “I share, therefore I am.” We use technology to define ourselves by sharing our thoughts and feelings as we’re having them. We used to think, “I have a feeling; I want to make a call.” Now our impulse is, “I want to have a feeling; I need to send a text.”

So, in order to feel more, and to feel more like ourselves, we connect. But in our rush to connect, we flee from solitude, our ability to be separate and gather ourselves. Lacking the capacity for solitude, we turn to other people but don’t experience them as they are. It is as though we use them, need them as spare parts to support our increasingly fragile selves.

We think constant connection will make us feel less lonely. The opposite is true. If we are unable to be alone, we are far more likely to be lonely. If we don’t teach our children to be alone, they will know only how to be lonely.

I am a partisan for conversation. To make room for it, I see some first, deliberate steps. At home, we can create sacred spaces: the kitchen, the dining room. We can make our cars “device-free zones.” We can demonstrate the value of conversation to our children. And we can do the same thing at work. There we are so busy communicating that we often don’t have time to talk to one another about what really matters. Employees asked for casual Fridays; perhaps managers should introduce conversational Thursdays. Most of all, we need to remember — in between texts and e-mails and Facebook posts — to listen to one another, even to the boring bits, because it is often in unedited moments, moments in which we hesitate and stutter and go silent, that we reveal ourselves to one another.

I spend the summers at a cottage on Cape Cod, and for decades I walked the same dunes that Thoreau once walked. Not too long ago, people walked with their heads up, looking at the water, the sky, the sand and at one another, talking. Now they often walk with their heads down, typing. Even when they are with friends, partners, children, everyone is on their own devices.

So I say, look up, look at one another, and let’s start the conversation.

AI to Pass Turing Test soon?

From Wired.com:


One hundred years after Alan Turing was born, his eponymous test remains an elusive benchmark for artificial intelligence. Now, for the first time in decades, it’s possible to imagine a machine making the grade.

Turing was one of the 20th century’s great mathematicians, a conceptual architect of modern computing whose codebreaking played a decisive part in World War II. His test, described in a seminal dawn-of-the-computer-age paper, was deceptively simple: If a machine could pass for human in conversation, the machine could be considered intelligent.

Artificial intelligences are now ubiquitous, from GPS navigation systems and Google algorithms to automated customer service and Apple’s Siri, to say nothing of Deep Blue and Watson — but no machine has met Turing’s standard. The quest to do so, however, and the lines of research inspired by the general challenge of modeling human thought, have profoundly influenced both computer and cognitive science.

There is reason to believe that code kernels for the first Turing-intelligent machine have already been written.

“Two revolutionary advances in information technology may bring the Turing test out of retirement,” wrote Robert French, a cognitive scientist at the French National Center for Scientific Research, in an Apr. 12 Science essay. “The first is the ready availability of vast amounts of raw data — from video feeds to complete sound environments, and from casual conversations to technical documents on every conceivable subject. The second is the advent of sophisticated techniques for collecting, organizing, and processing this rich collection of data.”

'Two revolutionary advances in information technology may bring the Turing test out of retirement.'“Is it possible to recreate something similar to the subcognitive low-level association network that we have? That’s experiencing largely what we’re experiencing? Would that be so impossible?” French said.

When Turing first proposed the test — poignantly modeled on a party game in which participants tried to fool judges about their gender; Turing was cruelly persecuted for his homosexuality –  the idea of “a subcognitive low-level association network” didn’t exist. The idea of replicating human thought, however, seemed quite possible, even relatively easy.

The human mind was thought to be logical. Computers run logical commands. Therefore our brains should be computable. Computer scientists thought that within a decade, maybe two, a person engaged in dialogue with two hidden conversants, one computer and one human, would be unable to reliably tell them apart.

That simplistic idea proved ill-founded. Cognition is far more complicated than mid-20th century computer scientists or psychologists had imagined, and logic was woefully insufficient in describing our thoughts. Appearing human turned out to be an insurmountably difficult task, drawing on previously unappreciated human abilities to integrate disparate pieces of information in a fast-changing environment.

“Symbolic logic by itself is too brittle to account for uncertainty,” said Noah Goodman, a computer scientist at Stanford University who models intelligence in machines. Nevertheless, “the failure of what we now call old-fashioned AI was very instructive. It led to changes in how we think about the human mind. Many of the most important things that have happened in cognitive science” emerged from these struggles, he said.

By the mid-1980s, the Turing test had been largely abandoned as a research goal (though it survives today in the annual Loebner prize for realistic chatbots, and momentarily realistic advertising bots are a regular feature of online life.) However, it helped spawn the two dominant themes of modern cognition and artificial intelligence: calculating probabilities and producing complex behavior from the interaction of many small, simple processes.

Unlike the so-called brute force computational approaches seen in programs like Deep Blue, the computer that famously defeated chess champion Garry Kasparov, these are considered accurate reflections of at least some of what occurs in human thought.

As of now, so-called probabilistic and connectionist approaches inform many real-world artificial intelligences: autonomous cars, Google searches, automated language translation, the IBM-developed Watson program that so thoroughly dominated at Jeopardy. They remain limited in scope — “If you say, ‘Watson, make me dinner,’ or ‘Watson, write a sonnet,’ it explodes,” said Goodman — but raise the alluring possibility of applying them to unprecedentedly large, detailed datasets.

“Suppose, for a moment, that all the words you have ever spoken, heard, written, or read, as well as all the visual scenes and all the sounds you have ever experienced, were recorded and accessible, along with similar data for hundreds of thousands, even millions, of other people. Ultimately, tactile, and olfactory sensors could also be added to complete this record of sensory experience over time,” wrote French in Science, with a nod to MIT researcher Deb Roy’s recordings of 200,000 hours of his infant son’s waking development.

He continued, “Assume also that the software exists to catalog, analyze, correlate, and cross-link everything in this sea of data. These data and the capacity to analyze them appropriately could allow a machine to answer heretofore computer-unanswerable questions” and even pass a Turing test.

Artificial intelligence expert Satinder Singh of the University of Michigan was cautiously optimistic about the prospects offered by data. “Are large volumes of data going to be the source of building a flexibly competent intelligence? Maybe they will be,” he said.

“But all kinds of questions that haven’t been studied much become important at this point. What is useful to remember? What is useful to predict? If you put a kid in a room, and let him wander without any task, why does he do what he does?” Singh continued. “All these sorts of questions become really interesting.

“In order to be broadly and flexibly competent, one needs to have motivations and curiosities and drives, and figure out what is important,” he said. “These are huge challenges.”

Should a machine pass the Turing test, it would fulfill a human desire that predates the computer age, dating back to Mary Shelley’s Frankenstein or even the golems of Middle Age folklore, said computer scientist Carlos Gershenson of the National Autonomous University of Mexico. But it won’t answer a more fundamental question.

“It will be difficult to do — but what is the purpose?” he said.

Poetry Wednesday: Numbers: A Poem On The Intimacy Of Math

Numbers

by Mary Cornish





I like the generosity of numbers.
The way, for example,
they are willing to count
anything or anyone:
two pickles, one door to the room,
eight dancers dressed as swans.

I like the domesticity of addition—
add two cups of milk and stir—
the sense of plenty: six plums
on the ground, three more
falling from the tree.

And multiplication's school
of fish times fish,
whose silver bodies breed
beneath the shadow
of a boat.

Even subtraction is never loss,
just addition somewhere else:
five sparrows take away two,
the two in someone else's
garden now.

There's an amplitude to long division,
as it opens Chinese take-out
box by paper box,
inside every folded cookie
a new fortune.

And I never fail to be surprised
by the gift of an odd remainder,
footloose at the end:
forty-seven divided by eleven equals four,
with three remaining.

Three boys beyond their mothers' call,
two Italians off to the sea,
one sock that isn't anywhere you look.

The Answer Man

An ancient poem was rediscovered—and the world swerved.
by Stephen Greenblatt  (The New Yorker | August 2011)

When I was a student, I used to go at the end of the school year to the Yale Co-op to see what I could find to read over the summer. I had very little pocket money, but the bookstore would routinely sell its unwanted titles for ridiculously small sums. They were jumbled together in bins through which I would rummage until something caught my eye. On one of my forays, I was struck by an extremely odd paperback cover, a detail from a painting by the Surrealist Max Ernst. Under a crescent moon, high above the earth, two pairs of legs—the bodies were missing—were engaged in what appeared to be an act of celestial coition. The book, a prose translation of Lucretius’ two-thousand-year-old poem “On the Nature of Things” (“De Rerum Natura”), was marked down to ten cents, and I bought it as much for the cover as for the classical account of the material universe.

Ancient physics is not a particularly promising subject for vacation reading, but sometime over the summer I idly picked up the book. The Roman poet begins his work (in Martin Ferguson Smith’s careful rendering) with an ardent hymn to Venus:

First, goddess, the birds of the air, pierced to the heart with your powerful shafts, signal your entry. Next wild creatures and cattle bound over rich pastures and swim rushing rivers: so surely are they all captivated by your charm and eagerly follow your lead. Then you inject seductive love into the heart of every creature that lives in the seas and mountains and river torrents and bird-haunted thickets, implanting in it the passionate urge to reproduce its kind.

Startled by the intensity, I continued, past a prayer for peace, a tribute to the wisdom of the philosopher Epicurus, a resolute condemnation of superstitious fears, and into a lengthy exposition of philosophical first principles. I found the book thrilling.

Lucretius, who was born about a century before Christ, was emphatically not our contemporary. He thought that worms were spontaneously generated from wet soil, that earthquakes were the result of winds caught in underground caverns, that the sun circled the earth. But, at its heart, “On the Nature of Things” persuasively laid out what seemed to be a strikingly modern understanding of the world. Every page reflected a core scientific vision—a vision of atoms randomly moving in an infinite universe—imbued with a poet’s sense of wonder. Wonder did not depend on the dream of an afterlife; in Lucretius it welled up out of a recognition that we are made of the same matter as the stars and the oceans and all things else. And this recognition was the basis for the way he thought we should live—not in fear of the gods but in pursuit of pleasure, in avoidance of pain.

As it turned out, there was a line from this work to modernity, though not a direct one: nothing is ever so simple. There were innumerable forgettings, disappearances, recoveries, and dismissals. The poem was lost, apparently irrevocably, and then found. This retrieval, after many centuries, is something one is tempted to call a miracle. But the author of the poem in question did not believe in miracles. He thought that nothing could violate the laws of nature. He posited instead what he called a “swerve”—Lucretius’ principal word for it was clinamen—an unexpected, unpredictable movement of matter.

The poem’s rediscovery prompted such a swerve. The cultural shift of the Renaissance is notoriously difficult to define, but it was characterized, in part, by a decidedly Lucretian pursuit of beauty and pleasure. The pursuit shaped the dress and the etiquette of courtiers, the language of the liturgy, the design and decoration of everyday objects. It suffused Leonardo da Vinci’s scientific and technological explorations, Galileo’s vivid dialogues on astronomy, Francis Bacon’s ambitious research projects, and Richard Hooker’s theology. Even works that were seemingly unrelated to any aesthetic ambition—Machiavelli’s analysis of political strategy, Walter Raleigh’s description of Guiana, Robert Burton’s encyclopedic account of mental illness—were crafted in such a way as to produce pleasure. And this pursuit, with its denial of Christian asceticism, enabled people to turn away from a preoccupation with angels and demons and to focus instead on things in this world: to conduct experiments without worrying about infringing on God’s jealously guarded secrets, to question authorities and challenge received doctrines, to contemplate without terror the death of the soul.

The recovery of “On the Nature of Things” is a story of how the world swerved in a new direction. The agent of change was not a revolution, an implacable army at the gates, or landfall on an unknown continent. When it occurred, nearly six hundred years ago, the key event was muffled and almost invisible, tucked away behind walls in a remote place. A short, genial, cannily alert man in his late thirties reached out one day, took a very old manuscript off a shelf, and saw with excitement what he had discovered. That was all; but it was enough.

By that time, Lucretius’ ideas had been out of circulation for centuries. In the Roman Empire, the literacy rate was never high, and after the Sack of Rome, in 410 C.E., it began to plummet. It is possible for a whole culture to turn away from reading and writing. As the empire crumbled and Christianity became ascendant, as cities decayed, trade declined, and an anxious populace scanned the horizon for barbarian armies, the ancient system of education fell apart. What began as downsizing went on to wholesale abandonment. Schools closed, libraries and academies shut their doors, professional grammarians and teachers of rhetoric found themselves out of work, scribes were no longer given manuscripts to copy. There were more important things to worry about than the fate of books. Lucretius’ poem, so incompatible with any cult of the gods, was attacked, ridiculed, burned, or ignored, and, like Lucretius himself, eventually forgotten.

The idea of pleasure and beauty that the work advanced was forgotten with it. Theology provided an explanation for the chaos of the Dark Ages: human beings were by nature corrupt. Inheritors of the sin of Adam and Eve, they richly deserved every miserable catastrophe that befell them. God cared about human beings, just as a father cared about his wayward children, and the sign of that care was anger. It was only through pain and punishment that a small number could find the narrow gate to salvation. A hatred of pleasure-seeking, a vision of God’s providential rage, and an obsession with the afterlife: these were death knells of everything Lucretius represented.

By chance, copies of “On the Nature of Things” somehow made it into a few monastery libraries, places that had buried, seemingly forever, the principled pursuit of pleasure. By chance, a monk laboring in a scriptorium somewhere or other in the ninth century copied the poem before it moldered away. And, by chance, this copy escaped fire and flood and the teeth of time for some five hundred years until, one day in 1417, it came into the hands of a man who proudly called himself Poggius Florentinus, Poggio the Florentine.
Poggio was, among other things, famous for the elegance of his script and for writing the best-known jokebook of its age, a chronicle of cynical tricksters, bawdy friars, unfaithful wives, and foolish husbands. He had served a succession of Roman Pontiffs as a scriptor—that is, a writer of official documents in the Papal bureaucracy—and, through adroitness and cunning, he had risen to the coveted position of Apostolic Secretary. He had access, as the very word “secretary” suggests, to the Pope’s secrets. But above all he was a book hunter, perhaps the greatest of his kind.

Italians had been obsessed with book hunting ever since the poet and scholar Petrarch brought glory on himself around 1330 by piecing together Livy’s monumental “History of Rome” and finding forgotten masterpieces by Cicero and Propertius. Petrarch’s achievement had inspired others to seek out lost classics that had been lying unread, often for centuries. The recovered texts were copied, edited, commented upon, and eagerly exchanged, conferring distinction on those who had found them and forming the basis for what became known as the “study of the humanities.” The “humanists,” as those who were devoted to this study were called, knew from carefully poring over the texts that had survived from classical Rome that many once famous books or parts of books were still missing.

As a humanist, Poggio had quite a few accomplishments. He uncovered an epic poem on the struggle between Rome and Carthage; the works of an ancient literary critic who had flourished during Nero’s reign and had written notes and glosses on classical authors; another critic who quoted extensively from lost epics written in imitation of Homer; a grammarian who wrote a treatise on spelling; a large fragment of a hitherto unknown history of the Roman Empire written by a high-ranking officer in the imperial Army, Ammianus Marcellinus. His salvaging of the complete text of the rhetorician Quintilian changed the curriculum of law schools and universities throughout Europe, and his discovery of Vitruvius’ treatise on architecture transformed the way buildings were designed. But it was in January, 1417, when Poggio found himself in a monastery library, that he made his greatest discovery. He put his hands on a long poem whose author he may have recalled seeing mentioned in other ancient works: “T. LUCRETI CARI DE RERUM NATURA.”

“On the Nature of Things,” by Titus Lucretius Carus, is not an easy read. Totalling seventy-four hundred lines, it is written in hexameters, the standard unrhymed six-beat lines in which Latin poets like Virgil and Ovid, imitating Homer’s Greek, cast their epic poetry. Divided into six untitled books, the poem yokes together moments of intense lyrical beauty; philosophical meditations on religion, pleasure, and death; and scientific theories of the physical world, the evolution of human societies, the perils and joys of sex, and the nature of disease. The language is often knotty and difficult, the syntax complex, and the over-all intellectual ambition astoundingly high.

The stuff of the universe, Lucretius proposed, is an infinite number of atoms moving randomly through space, like dust motes in a sunbeam, colliding, hooking together, forming complex structures, breaking apart again, in a ceaseless process of creation and destruction. There is no escape from this process. When we look up at the night sky and marvel at the numberless stars, we are not seeing the handiwork of the gods or a crystalline sphere. We are seeing the same material world of which we are a part and from whose elements we are made. There is no master plan, no divine architect, no intelligent design. Nature restlessly experiments, and we are simply one among the innumerable results: “We are all sprung from celestial seed; all have that same father, from whom our fostering mother earth receives liquid drops of water, and then teeming brings forth bright corn and luxuriant trees and the race of mankind, brings forth all the generations of wild beasts, providing food with which all nourish their bodies and lead a sweet life and beget their offspring.”

All things, including the species to which we belong, have evolved over vast stretches of time. The evolution is random, though in the case of living organisms it involves a principle of natural selection. That is, species that are suited to survive and to reproduce successfully endure, at least for a time; those which are not so well suited die off quickly. Other species existed and vanished before we came onto the scene; our kind, too, will vanish one day. Nothing—from our own species to the sun—lasts forever. Only the atoms are immortal.
In a universe so constituted, Lucretius argued, it is absurd to think that the earth and its inhabitants occupy a central place, or that the world was purpose-built to accommodate human beings: “The child, like a sailor cast forth by the cruel waves, lies naked upon the ground, speechless, in need of every kind of vital support, as soon as nature has spilt him forth with throes from his mother’s womb into the regions of light.” There is no reason to set humans apart from other animals, no hope of bribing or appeasing the gods, no place for religious fanaticism, no call for ascetic self-denial, no justification for dreams of limitless power or perfect security, no rationale for wars of conquest or self-aggrandizement, no possibility of triumphing over nature. Instead, he wrote, human beings should conquer their fears, accept the fact that they themselves and all the things they encounter are transitory, and embrace the beauty and the pleasure of the world.

Almost nothing is known about the poem’s author, except for a brief biographical sketch by St. Jerome, the great fourth-century Church Father. In the entry for 94 B.C.E., Jerome noted: “Titus Lucretius, poet, is born. After a love-philtre had turned him mad, and he had written, in the intervals of his insanity, several books which Cicero revised, he killed himself by his own hand in the forty-fourth year of his age.” These lurid details have shaped all subsequent representations of Lucretius, including a celebrated Victorian poem in which Tennyson imagined the voice of the mad, suicidal philosopher tormented by erotic fantasies.
Modern scholarship suggests that Jerome’s biographical claims, written more than four centuries after the poet’s death, should be regarded with skepticism. Lucretius’ personal life remains a mystery that no one at this distance is likely to solve. It is possible, however, to know something about his intellectual biography. “On the Nature of Things” is clearly the work of a disciple who is transmitting ideas that had been developed in Greece centuries earlier. Epicurus was Lucretius’ philosophical messiah, and his vision may be traced to a single incandescent idea: that everything that has ever existed and everything that will ever exist is put together out of what the Roman poet called “the seeds of things,” indestructible building blocks, irreducibly small in size, unimaginably vast in number. The Greeks had a word for these invisible building blocks, things that, as they conceived them, could not be divided any further: atoms.

The notion of atoms was only a dazzling speculation; there was no way to get any empirical proof and wouldn’t be for more than two thousand years. But Epicurus used this conjecture to argue that there are no supercategories of matter, no hierarchy of elements. Heavenly bodies are not divine beings, nor do they move through the void under the guidance of gods. And, though the natural order is unimaginably vast and complex, it is nonetheless possible to understand something of its basic constitutive elements and its universal laws. Indeed, such understanding is one of life’s deepest pleasures.

Pleasure is perhaps the key to comprehending the powerful impact of Epicurus’ philosophy. Epicurus’ enemies—and the Church especially—seized upon his celebration of pleasure and invented malicious stories about his supposed debauchery, taking note of his unusual inclusion of women as well as men among his followers. He “vomited twice a day from overindulgence,” in one account, and spent a fortune on feasting. In reality, he seems to have lived a conspicuously simple and frugal life. “Send me a little pot of cheese,” he once wrote to a friend, “that, when I like, I may fare sumptuously.” It is impossible to live pleasurably, one of his disciples wrote, “without living prudently and honorably and justly, and also without living courageously and temperately and magnanimously, and without making friends, and without being philanthropic.”

This philosophy of pleasure, at once passionate, scientific, and visionary, radiated from almost every line of Lucretius’ poetry. Even a quick glance at the first few pages of the manuscript would have convinced Poggio that he had discovered something remarkable. What he could not have grasped, without carefully reading through the work, was that he was unleashing something that threatened the whole structure of his intellectual universe. Had he understood this threat, he might have said, as Freud supposedly said to Jung, when they sailed into New York Harbor, “Don’t they know we are bringing them the plague?”
There are moments, rare and powerful, in which a writer, long vanished, seems to stand in your presence and speak to you directly, as if he bore a message meant for you above all others. When I first read “On the Nature of Things,” it struck such a chord within me. The core of Lucretius’ poem is a profound, therapeutic meditation on the fear of death, and that fear dominated my childhood. It was not fear of my own death that so troubled me; I had the usual child’s intimation of immortality. It was, rather, my mother’s absolute certainty that she was destined for an early death.

My mother was not afraid of the afterlife: like most Jews, she had only a hazy sense of what might lie beyond the grave, and she gave it very little thought. It was death itself—simply ceasing to be—that terrified her. As far back as I can remember, she brooded obsessively on the imminence of her end, invoking it again and again, especially at moments of parting. My life was full of extended, operatic scenes of farewell. When she went with my father from Boston to New York for the weekend, when I went off to summer camp, and even—when things were especially hard for her—when I simply left the house for school, she clung tightly to me, speaking of her fragility and of the distinct possibility that I would never see her again. If we walked somewhere together, she would frequently come to a halt, as if she were about to keel over. Sometimes she would show me a vein pulsing in her neck and, taking my finger, make me feel it for myself, the sign of her heart dangerously racing.

She must have been in her late thirties when my own memories of her fears begin, and those fears evidently went back much further in time. They seem to have taken root about a decade before my birth, when her younger sister, only sixteen years old, died of strep throat. This event—one all too familiar before the introduction of penicillin—was still an open wound: my mother spoke of it constantly, weeping quietly, and making me read and reread the poignant letters that her sister had written through the course of her fatal illness.

I understood early on that my mother’s “heart”—the palpitations that brought her and everyone around her to a halt—was a life strategy. It was a way to express both anger (“You see how upset you have made me”) and love (“You see how I am still doing everything for you, even though my heart is about to break”). It was an acting out, a rehearsal, of the extinction that she feared. It was, above all, a way to compel attention from my father, my brother, and me, and to demand our love. But this understanding did not make its effect upon my childhood significantly less intense: I loved my mother and dreaded losing her. I was hardly equipped to untangle psychological strategy from dangerous symptom. (I don’t imagine that she was, either.) And, as a child, I had no means to gauge the weirdness of this constant harping on impending death and this freighting of every farewell with finality.

As it turned out, my mother lived to a month shy of her ninetieth birthday. She was still in her fifties when I encountered “On the Nature of Things.” By then my dread of her dying had become entwined with a painful perception that she had blighted much of her life—and cast a shadow on my own—in the service of her obsessive fear. Lucretius’ words therefore rang out with a terrible clarity: “Death is nothing to us.” His lines (here in a translation by the seventeenth-century poet John Dryden) went right to the heart of her anxiety and my own:

So, when our mortal frame shall be disjoin’d,
The lifeless lump uncoupled from the mind,
From sense of grief and pain we shall be free;
We shall not feel, because we shall not be.
Though earth in seas, and seas in heaven were lost,
We should not move, we only should be toss’d.
Nay, e’en suppose when we have suffer’d fate
The soul should feel in her divided state,
What’s that to us? for we are only we,
While souls and bodies in one frame agree.
Nay, though our atoms should revolve by chance,
And matter leap into the former dance;
Though time our life and motion could restore,
And make our bodies what they were before,
What gain to us would all this bustle bring?
The new-made man would be another thing.


To spend your existence in the grip of anxiety about death, Lucretius wrote, is folly. It is a sure way to let your life slip from you incomplete and unenjoyed. And, in so arguing, he gave voice to a thought I had not yet quite allowed myself to articulate: to inflict this anxiety on others is manipulative and cruel.

When Lucretius’ poem returned to circulation in 1417, it seems to have struck some early readers with the same personal intensity—the sense of direct address across an abyss—that I experienced. But, of course, the issues were vastly different. To people haunted by images of the bleeding Christ, gripped by a terror of Hell, and obsessed with escaping the purgatorial fires of the afterlife, Lucretius offered a vision of divine indifference. There was no afterlife, no system of rewards and punishments meted out from on high. Gods, by virtue of being gods, could not possibly be concerned with the doings of human beings. One simple name for the plague that Lucretius brought, and a charge frequently levelled against him then and since, is atheism.

Some six or seven decades after Poggio returned the poem to circulation, atomism was viewed as a serious threat to Christianity. Atomist books were burned; the clergy in Florence prohibited the reading of Lucretius in schools. The sense of threat intensified when Protestants mounted their assault on Catholic doctrine. That assault did not depend on atomism—Luther and Zwingli and Calvin were scarcely Epicureans—but for the militant, embattled forces of the Counter-Reformation it was as if the resurgence of ancient materialism had opened a dangerous second front. Indeed, atomism seemed to offer the Reformers access to an intellectual weapon of mass destruction. The Church was fiercely determined not to allow anyone to lay hands on this weapon, and its ideological arm, the Inquisition, was alerted to detect the telltale signs of proliferation.

Poems are difficult to silence. At the time that the Church was attempting to suppress the text, a young Florentine was copying out for himself the whole of “On the Nature of Things.” He was too cunning to mention the work directly in the famous books he went on to write. But the handwriting was conclusively identified in 1961: the copy was made by Niccolò Machiavelli. Thomas More engaged with Epicureanism more openly in his most famous work, “Utopia,” in which the inhabitants of his imaginary land are convinced that “either the whole or the most part of human happiness” lies in the pursuit of pleasure. His use of the philosophy for the population of this alien island showed that the ideas recovered by the humanists seemed compellingly vital and at the same time still utterly weird. Reinjected into the intellectual bloodstream of Europe after long centuries, they were, in effect, voices from another world, a world as different as Vespucci’s Brazil was from England.

But the poem spread, and, as it did, its ideas filtered into popular culture. On the London stage in the mid-fifteen-nineties, Mercutio teased Romeo with this fantastical description of Queen Mab:

She is the fairies’ midwife, and she comes
In shape no bigger than an agate stone
On the forefinger of an alderman,
Drawn with a team of little atomi
Athwart men’s noses as they lie asleep.


“A team of little atomi”: Shakespeare expected that his audience would immediately understand what Mercutio was comically conjuring. That is interesting in itself, and still more interesting in the context of a tragedy that broods upon the compulsive power of desire in a world whose main characters conspicuously abjure any prospect of life after death:

Here, here will I remain
With worms that are thy chambermaids. O, here
Will I set up my everlasting rest.


The author of “Romeo and Juliet” shared his interest in Lucretian materialism with Spenser, Donne, Bacon, and others. He could have discussed it with his fellow-playwright Ben Jonson, whose own signed copy of “On the Nature of Things” has survived and is today in the Houghton Library, at Harvard. And he certainly would have encountered Lucretius in one of his favorite books: Montaigne’s “Essays.”

The “Essays,” first published in 1580, contain almost a hundred direct quotations from “On the Nature of Things.” But, beyond any particular passage, there is a profound affinity between Lucretius and Montaigne. Montaigne shared Lucretius’ contempt for a morality enforced by nightmares of the afterlife; he clung to the importance of his own senses and the evidence of the material world; he intensely disliked ascetic self-punishment and violence against the flesh; he treasured inward freedom and contentment. In grappling with the fear of death, in particular, he was influenced by Lucretian materialism. He once saw a man die, he recalled, who complained bitterly in his last moments that destiny was preventing him from finishing the book he was writing. The absurdity of the regret, in Montaigne’s view, is best conveyed by lines from Lucretius: “But this they fail to add: that after you expire / Not one of all these things will fill you with desire.” As for himself, Montaigne wrote, “I want death to find me planting my cabbages, but careless of death, and still more of my unfinished garden.”

By the seventeenth century, the lure of the poem was too great to contain. The brilliant French astronomer, philosopher, and priest Pierre Gassendi devoted himself to an ambitious attempt to reconcile Epicureanism and Christianity, and one of his most remarkable students, the playwright Molière, undertook to produce a verse translation of “De Rerum Natura” (which does not, unfortunately, survive). In England, the wealthy diarist John Evelyn translated the first book of Lucretius’ poem, and Isaac Newton declared himself an atomist. By the following century, Thomas Jefferson owned at least five Latin editions of “De Rerum Natura,” along with translations of the poem into English, Italian, and French. To a correspondent who wanted to know his philosophy of life, Jefferson wrote, “I too am an Epicurean.”

What lay beyond the horizon were the astonishing empirical observations and experimental proofs of the intuitions of ancient atomism. In the nineteenth century, when Charles Darwin set out to solve the mystery of the origin of species, he did not have to draw on Lucretius’ vision of an entirely natural, unplanned process of creation and destruction, renewed by sexual reproduction. That vision had directly influenced the evolutionary theories of Darwin’s grandfather Erasmus Darwin, but Charles could base his arguments on his own work in the Galápagos and elsewhere. So, too, when Einstein wrote of atoms, his thought rested on experimental and mathematical science, not upon ancient philosophical speculation. But that speculation, as Einstein acknowledged, had led the way to the proofs upon which modern atomism depends. That the ancient poem can now be safely left unread, that the drama of its loss and recovery can fade into oblivion—these are the greatest signs of Lucretius’ absorption into modern thought.

The manuscript that Poggio found in 1417 has itself been lost to time—its letters perhaps scraped away and the parchment recycled for a more pious purpose. The crucial conduit through which the ancient poem, all but dormant for a thousand years before the humanist encountered it, returned to circulation was an elegant copy prepared by Poggio’s wealthy bibliophile friend Niccolò Niccoli. Niccoli bequeathed his valuable collection to Florence, and today his Lucretius manuscript is preserved in the cool gray-and-white Laurentian Library that Michelangelo designed for the Medici. Labelled “Codex Laurentianus 35.30,” it is a modest volume, bound in fading, tattered red leather inlaid with metal, a chain attached to the bottom of the back cover. There is little to distinguish it physically from many other manuscripts in the collection, apart from the fact that a reader is given latex gloves to wear when it is delivered to the desk.

My gloved hands trembled with excitement recently when I held it and looked at its elegant lines. Many years have passed since I picked up the ten-cent paperback from the bin in New Haven. My mother has been gone for more than a decade, cruelly weaned of her fear of death by the slow asphyxiation of congestive heart failure. My father, blessed with a quicker parting, is long dead as well, along with the whole crowded generation of aunts and uncles who seemed at one point to be arrayed as a formidable bulwark against my own extinction. Of necessity, I have taken in the significance of one of the celebrated aphorisms of Lucretius’ master, Epicurus: “Against other things it is possible to obtain security, but when it comes to death we human beings all live in an unwalled city.”

I have taken in, as well, much that pulls against Lucretius’ account of the nature of things. In a secular, skeptical culture, it is not a sizable consolation to know that there is no afterlife. There may be some reassurance in realizing that the dead cannot possibly miss the living, but, as I’ve learned, that realization does not free the living from missing the dead. Did the ancient poet not experience this pain or think it worth addressing? Anyone who thought, as Lucretius did, that it was a particular pleasure to gaze from shore at a ship foundering in wild seas or to stand on a height and behold armies clashing on a plain—“not because any man’s troubles are a delectable joy, but because to perceive what ills you are free from yourself is pleasant”—is not someone I can find an entirely companionable soul. I am, rather, with Shakespeare’s Miranda, who, harrowed by the vision of a shipwreck, cries, “O, I have suffered / With those I saw suffer!” There is something disturbingly cold in Lucretius’ account of pleasure, an account that leads him to advise those who are suffering from the pangs of intense love to reduce their anguish by taking many lovers.

All the same, in the great Laurentian Library, surrounded by the achievements of Renaissance Florence, I felt the full force of what this ancient Roman poet had bequeathed to the world, a tortuous trail that led from the celebration of Venus, past broken columns, high-domed churches, and inquisitorial fires, toward Jefferson, Darwin, and Einstein. And I registered, too, what Lucretius had given to me personally: the means to elude the suffocating grasp of my mother’s fears and the encouragement to take deep pleasure in my brief time on the shores of light. ♦
