We Create the World

"When you have an awareness of anything internally, you perceive that externally. We really do, I believe, create the world that we live in. The word ‘eye’, in its Sanskrit and Hebrew root, means fountain. In other words, this is not an organ that's receiving vibrations from what's out there going through the brain and being interpreted. It's a projector."

~ Hubert Selby, Jr., from Memories, Dreams & Addictions. Interview with Ellen Burstyn. Special feature on Requiem for a Dream, Director's Cut DVD release. (2001)

To Think Oneself into the Minds of Others

Excerpt from “Only Love and then Oblivion,” by Ian McEwan, the Guardian, September 15, 2001:

I suspect that in between times, when we are not consuming news, the majority of us are not meditating on recent foreign policy failures, or geopolitical strategy, or the operational range of helicopter gunships.

Instead, we remember what we have seen, and we daydream helplessly. . .

This is the nature of empathy, to think oneself into the minds of others. These are the mechanics of compassion: you are under the bedclothes, unable to sleep, and you are crouching in the brushed-steel lavatory at the rear of the plane, whispering a final message to your loved one. There is only that one thing to say, and you say it. All else is pointless. You have very little time before some holy fool, who believes in his place in eternity, kicks in the door, slaps your head and orders you back to your seat. 23C. Here is your seat belt. There is the magazine you were reading before it all began. . .

If the hijackers had been able to imagine themselves into the thoughts and feelings of the passengers, they would have been unable to proceed. It is hard to be cruel once you permit yourself to enter the mind of your victim. Imagining what it is like to be someone other than yourself is at the core of our humanity. It is the essence of compassion, and it is the beginning of morality.

Experimenting with Forms

Japanese Garden, Dawes Arboretum (March 19, 2011)

“We are the miracle of force and matter making itself over into imagination and will. Incredible. The Life Force experimenting with forms. You for one. Me for another. The Universe has shouted itself alive. We are one of the shouts.”

~ Ray Bradbury

The Range of Human Imagination

Analogies prove nothing, but they can make one feel more at home.

~ Sigmund Freud, from Introduction to Psychoanalysis

Excerpt from Once Before Time: A Whole Story of the Universe by Martin Bojowold:

Once theory pushes forward to a possible understanding of the big bang and the remaining universe, the temptation to explain the emergence of the universe itself becomes overwhelming. Interpretations of theories and their mathematical solutions concerning entire worldviews indeed offer a high degree of fascination. But in too direct and supposedly generally valid an interpretation there lies, especially in this case, a great danger—not least because theories relevant for such questions will for all foreseeable time remain in their infancy. Physics is, after all, even if we disregard its big sister philosophy, not alone in this business. And yet a comparison of different worldviews offers a certain charm, and certainly some knowledge, too.

One should not underestimate myths and what they can teach us about ourselves and the progress we have made. Take the Summer Palace in modern Beijing, a beautiful sprawling park built as the summer retreat of Empress Dowager Cixi. On a small island in a man-made lake, facing the Tower of Buddhist Incense and the Sea of Wisdom Temple on the slope of Longevity Hill which rises from the shore, stand the Hall of Embracing the Universe. It is a small, humble building in the style of its time, the fringes of its roof rising optimistically upward to aim at the sky. The Hall of Embracing the Universe tells us everything there is to know about humanity and the world: It was initially called the Hall of Watching the Moon Toad to honor its role in observing the moonrise; nowadays, the Hall of Embracing the Universe is a souvenir shop.

Hall of Embracing the Universe, completed in Emperor Qianlong's reign (1736-1795)

Surprisingly often, one can find parallels between ideas stemming from the most diverse traditions, an observation probably not hinting at an ember of truth but rather traceable back to the fact that the range of human imagination is despite its excesses, actually quite small.

Room for Both the Wind and the Lion

From “Mass Animal Deaths: An Environmental Whodunit,” by James Gorman, New York Times, Jan. 9, 2011:

Michael Shermer, the founding publisher of Skeptic magazine and a Scientific American columnist …uses a common scenario to explain why we believe in things that may not be there — hominids on the savannah hearing a rustling in the tall grass.  The one who thinks, “It’s a lion!” and escapes quickly survives to propagate her genes, thus fostering a kind of protective alarmism in her descendants. Another might think, “There’s always some kind of rustling in the tall grass, it’s probably the wind,” and keep on grooming. If he guesses wrong, the downside is being eaten by the lion. Thus, no offspring and no propagation of the “don’t worry, be happy” genes.

Of course, people have both modes of thought, perhaps because rustling is usually caused by the wind, and the hominid who is too alarmist is always running away from nothing and probably too exhausted and too anxiety-ridden to mate. So there’s room for both the wind and the lion in human minds.

Branches from a Single Root

W.S. Merwin from “The Garden & the Sword,” an interview with Joel Whitney, Tricycle Magazine, Winter 2010:

I don’t think we have imagination apart from the environment. And I don’t think we have an existence apart from the environment either. And if the imagination isn’t about our existence, I don’t know what it’s about. It’s not about making money, that’s for sure.

…If you’re looking for neat formulaic answers in Dogen, you don’t find them. You don’t find them in Keizan, either. You have to come at them from a different part of your own mind. That’s the part of Zen practice that’s attractive to me. But it’s not unique to Zen. It’s there in Taoism. It probably was there in parts of the practice that became Greek Orthodoxy, that came out of the desert. The origins of all of those things are extremely ancient; they’re older than what we think of as the beginnings of Buddhism. The origin of Taoism may be completely on its own, but all of them go back to shamanism. And we don’t know know the history of shamanism; it’s all speculation. They link in my mind to things which are incredibly ancient.

…the link between the imagination—which to me is the great pinnacle of humanity, the imagination that makes the arts and makes compassion—is ancient in our species and goes way back. And it’s never been separate. And when you get any aspect of the culture that tries to separate it, it’s destructive and suicidal.

Take them away, names like Buddhism. I’m impatient with them. There’s something beyond all that, beneath all that that they all share, that they all come from. They are branches from a single root. And that’s what one has to pay attention to.

There is a Boundary to Looking

Full moon rise over Woody Mountain.

photo by Pez Owen

Turning-Point
by Rainer Maria Rilke, translated by Stephen Mitchell

The road from intensity to greatness
passes through sacrifice.         —Kassner

For a long time he attained it in looking.
Stars would fall to their knees
beneath his compelling vision.
Or as he looked on, kneeling,
his urgency's fragrance
tired out a god until
it smiled at him in its sleep.

Towers he would gaze at so
that they were terrified:
building them up again, suddenly, in an instant!
But how often the landscape,
overburdened by day,
came to rest in his silent awareness, at nightfall.

Animals trusted him, stepped
into his open look, grazing,
and the imprisoned lions
stared in as if into an incomprehensible freedom;
birds, as it felt them, flew headlong
through it; and flowers, as enormous
as they are to children, gazed back
into it, on and on.

And the rumor that there was someone
who knew how to look,
stirred those less
visible creatures:
stirred the women.

Looking how long?
For how long now, deeply deprived,
beseeching in the depths of his glance?

When he, whose vocation was Waiting, sat far from home—
the hotel's distracted unnoticing bedroom
moody around him, and in the avoided mirror
once more the room, and later
from the tormenting bed
once more:
then in the air the voices
discussed, beyond comprehension,
his heart, which could still be felt;
debated what through the painfully buried body
could somehow be felt—his heart;
debated and passed their judgment:
that it did not have love.

(And denied him further communions.)

For there is a boundary to looking.
And the world that is looked at so deeply
wants to flourish in love.

Work of the eyes is done, now
go and do heart-work
on all the images imprisoned within you; for you
overpowered them: but even now you don't know them.
Learn, inner man, to look at your inner woman,
the one attained from a thousand
natures, the merely attained but
not yet beloved form.

[Thanks, Ryan!]

What do you want to be?

Calvinosaurus, from Calvin and Hobbes by Bill Watterson

Dinosaur
by Bruce Holland Rogers, from The Sun Magazine, July 2006

When he was very young, he waved his arms, gnashed the teeth of his massive jaws, and tromped around the house so that the dishes trembled in the china cabinet. “Oh, for goodness sake,” his mother said. “You are not a dinosaur! You are a human being!” Since he was not a dinosaur, he thought for a time that he might be a pirate. “Seriously,” his father said at some point, “what do you want to be?” A fireman, then. Or a policeman. Or a soldier. Some kind of hero.

But in high school they gave him tests and told him he was very good with numbers. Perhaps he would like to be a math teacher? That was respectable. Or a tax accountant? He could make a lot of money doing that. It seemed a good idea to make money, what with falling in love and thinking about raising a family. So he was a tax accountant, even though he sometimes regretted that it made him, well, small. And he felt even smaller when he was no longer a tax accountant, but a retired tax accountant. Still worse, a retired tax accountant who forgot things. He forgot to take the garbage to the curb, forgot to take his pill, forgot to turn his hearing aid back on. Every day it seemed he had forgotten more things, important things, like which of his children lived in San Francisco and which of his children were married or divorced.

Then one day when he was out for a walk by the lake, he forgot what his mother had told him. He forgot that he was not a dinosaur. He stood blinking his dinosaur eyes in the bright sunlight, feeling the familiar warmth on his dinosaur skin, watching dragonflies flitting among the horsetails at the water’s edge.

The Screen is Always There

Canton Place, Ohio (1980), Hiroshi SugimotoExcerpt from Not Always So: Practicing the True Spirit of Zen, by Shunryu Suzuki:

Our everyday life is like a movie playing on the wide screen. Most people are interested in the picture on the screen without realizing there is a screen. When the movie stops and you don't see anything anymore, you think, "I must come again tomorrow evening. I will come back and see another show." When you are just interested in the movie on the screen and it ends, then you expect another show tomorrow, or maybe you are discouraged because there is nothing good on right now. You don't realize the screen is always there.

But when you are practicing, you realize that your mind is like a screen. If the screen is colorful—colorful enough to attract people—then it will not serve its purpose. So to have a screen which is not colorful—to have a pure, plain white screen—is the most important point. But most people are not interested in the pure white screen.

I think it is good to be excited by seeing a movie. To some extent you can enjoy the movie because you know that it is a movie. Even though you have no idea of the screen, still your interest is based on an understanding that this is a movie with a screen and there is a projector or something artificial. So you can enjoy it. That is how we enjoy our life. If you have no idea of the screen or the projector, perhaps you cannot see it as a movie.

Zazen practice is necessary to know the kind of screen you have and to enjoy our life as you enjoy movies in the theater. You are not afraid of the screen. You do not have any particular feeling for the screen, which is just a white screen. So you are not afraid of your life at all. You enjoy something you are afraid of. You enjoy something that makes you angry or that makes you cry, and you enjoy the crying and the anger too.

If you have no idea of the screen, then you will be afraid of enlightenment. "What is it? Oh, my!" [laughter] If someone attains enlightenment, you may ask him about the experience, you may say,"Oh, no! That is not for me." But it is just a movie. Something for you to enjoy. And if you want to enjoy the movie, you should know that it is the combination of film and light and white screen,and that the most important thing is the plain white screen.

The white screen is not something that you can actually attain; it is something you always have. The reason you don't feel you have it is because your mind is too busy to realize it. Once in a while you should stop all your activities and [notice your] screen. That is zazen. That is the foundation of our everyday life and our meditation practice.

Where is everybody?

"And now here's the thing. It takes a time like this for you to find out how sore your heart has been, and, moreover, all the while you thought you were going around idle terribly hard work was taking place. Hard, hard work, excavation and digging, mining, moiling through tunnels, heaving, pushing, moving rock, working, working, working, working, Theater of the Mindpanting, hauling, hoisting. And none of this work is seen from the outside. It's internally done. It happens because you are powerless and unable to get anywhere, to obtain justice or have requital, and therefore in yourself you labor, you wage and combat, settle scores, remember insults, fight, reply, deny, blab, denounce, triumph, outwit, overcome, vindicate, cry, persist, absolve, die and rise again. All by yourself? Where is everybody? Inside your breast and skin, the entire cast."

~ Saul Bellow, from The Adventures of Augie March

Where We Live

"It's no wonder we don't defend the land where we live. We don't live here. We live in television programs and movies and books and with celebrities and in heaven and by rules and laws and abstractions created by people far away and we live anywhere and everywhere except in our particular bodies on this particular land at this particular moment in these particular circumstances."

~ Derrick Jensen, from Endgame, Volume 2: Resistance

Experiences that We Know are Not Real

Excerpt from How Pleasure Works: The New Science of Why We Like What We Like by Paul Bloom:

How Pleasure WorksHow do Americans spend their leisure time? The answer might surprise you. The most common voluntary activity is not eating, drinking alcohol, or taking drugs. It is not socializing with friends, participating in sports, or relaxing with the family. While people sometimes describe sex as their most pleasurable act, time-management studies find that the average American adult devotes just four minutes per day to sex.

Our main leisure activity is, by a long shot, participating in experiences that we know are not real. When we are free to do whatever we want, we retreat to the imagination—to worlds created by others, as with books, movies, video games, and television (over four hours a day for the average American), or to worlds we ourselves create, as when daydreaming and fantasizing. While citizens of other countries might watch less television, studies in England and the rest of Europe find a similar obsession with the unreal.

This is a strange way for an animal to spend its days. Surely we would be better off pursuing more adaptive activities—eating and drinking and fornicating, establishing relationships, building shelter, and teaching our children. Instead, 2-year-olds pretend to be lions, graduate students stay up all night playing video games, young parents hide from their offspring to read novels, and many men spend more time viewing Internet pornography than interacting with real women. One psychologist gets the puzzle exactly right when she states on her Web site: "I am interested in when and why individuals might choose to watch the television show Friends rather than spending time with actual friends."

One solution to this puzzle is that the pleasures of the imagination exist because they hijack mental systems that have evolved for real-world pleasure. We enjoy imaginative experiences because at some level we don't distinguish them from real ones. This is a powerful idea, one that I think is basically—though not entirely—right...

...Just as artificial sweeteners can be sweeter than sugar, unreal events can be more moving than real ones. There are three reasons for this.

First, fictional people tend to be wittier and more clever than friends and family, and their adventures are usually much more interesting. I have contact with the lives of people around me, but this is a small slice of humanity, and perhaps not the most interesting slice. My real world doesn't include an emotionally wounded cop tracking down a serial killer, a hooker with a heart of gold, or a wisecracking vampire. As best I know, none of my friends has killed his father and married his mother. But I can meet all of those people in imaginary worlds.

Second, life just creeps along, with long spans where nothing much happens. The O.J. Simpson trial lasted months, and much of it was deadly dull. Stories solve this problem—as the critic Clive James once put it, "Fiction is life with the dull bits left out." This is one reason why Friends is more interesting than your friends.

Finally, the technologies of the imagination provide stimulation of a sort that is impossible to get in the real world. A novel can span birth to death and can show you how the person behaves in situations that you could never otherwise observe. In reality you can never truly know what a person is thinking; in a story, the writer can tell you.

That Spark Will Never Be a Commodity

Excerpt from “America’s Real Dream Team,” by Thomas L. Friedman, New York Times (March 21, 2010):

Photo by Felipe T. Marques In today’s wired world, the most important economic competition is no longer between countries or companies. The most important economic competition is actually between you and your own imagination. Because what your kids imagine, they can now act on farther, faster, cheaper than ever before — as individuals. Today, just about everything is becoming a commodity, except imagination, except the ability to spark new ideas.

If I just have the spark of an idea now, I can get a designer in Taiwan to design it. I can get a factory in China to produce a prototype. I can get a factory in Vietnam to mass manufacture it. I can use Amazon.com to handle fulfillment. I can use freelancer.com to find someone to do my logo and manage by backroom. And I can do all this at incredibly low prices. The one thing that is not a commodity and never will be is that spark of an idea.

Both Respect and Imagination

Excerpt from the preface of From Disgust to Humanity: Sexual Orientation and Constitutional Law (Inalienable Rights) by Martha Nussbaum:

Today, large segments of the Christian Right openly practice a politics based upon disgust. Depicting the sexual practices of lesbians and, especially, of gay men as vile and revolting, they suggest that such practices contaminate and defile society, producing decay and degeneration…Although the influence of such appeals peaked, perhaps, in the 1980s and 1990s, and has since been declining, the politics of disgust continues to exercise influence, often in more subtle and unstated ways. We need, then, to understand why it is not a good approach to politics and law in a democratic society.

The politics of disgust is profoundly at odds with the abstract idea of a society based on the equality of all citizens, in which all have a right to the equal protection of the laws. It says that the mere fact that you happen to make me want to vomit is reason enough for me to treat you as a social pariah, denying you some of your most basic entitlements as a citizen.

…the politics of disgust is alive and well in America today, as many groups aggressively depict same-sex practices in such a way as to arouse disgust and then draw on that reaction when campaigning against the legalization of same-sex marriage, or nondiscrimination laws. Such appeals are often seen as not politically correct today, so other arguments are increasingly put forward. Disgust, however, has not gone away. We still need to understand its force, and why arguments based upon it are bad political arguments. A closer study of the emotion of disgust and the ways in which it has been used politically through history will suggest some powerful arguments against disgust’s apostles in theory and in practice, by showing how that emotion expresses a universal human discomfort with bodily reality, but then uses that discomfort to target and subordinate vulnerable minorities.

…Disgust relies on moral obtuseness. It is possible to view another human being as a slimy slug or a piece of revolting trash only if one has never made a serious good-faith attempt to see the world through that person’s eyes or to experience that person’s feelings. Disgust imputes to the other a subhuman nature. How, by contrast, do we ever become able to see one another as human? Only through the exercise of imagination. Humanity does not automatically reveal itself to strangers. No placard hung on the front of a fellow citizen announces that this one is a full-fledged human being. Seeing the shape of a human being before us, we always have choices to make: will we impute full equal humanity to that shape, or something less? Only by imagining how the world looks through that person’s eyes does one get to the point of seeing the other person as a someone and not a something. (Sadly, racial minorities have long been seen as somethings rather than someones, and women are all too frequently so seen today, given the ever-present phenomenon of sexual “object-ification,” in which a person is treated as a mere thing.) That crucial imaginative engagement has been sadly and sorely lacking in majority dealings with lesbians and gay lives…

The politics of humanity, as I shall use the term, includes respect. But respect, as usually conceived, is not sufficient for it: something else, something closer to love, must also be involved. First of all, we are unlikely to achieve full respect for one another unless we can do something else first – see the other as a center of perception, emotion, and reason, rather than an inert object. Put that way, it might appear that this imaginative and emotional attitude is a mere instrument to a respect that might be arrived at by some other route. However, respect without this attitude is certainly no a complete basis for political action in a diverse society: for only imagination animates the cold and abstract categories of morality and law, turning them into the ways we can live together. So, respect is politically incomplete without imagination.

One may, however, make a stronger claim, and I shall defend this claim: the capacity for imaginative and emotional participation in the lives of others is an essential ingredient of any respect worthy of the name. Only this capacity makes real an ability that is a key part of respect, the ability to see the other as an end, not as a mere means. The politics of humanity includes, then, both respect and imagination, and imagination understood as an ingredient essential to respect itself.

Not Beyond Your Imagination

James Cameron, in conversation with Elvis Mitchell for a special online edition of The Treatment, recorded live at a benefit for the Natural Resources Defense Council:


“I’ve always believed in exploration. I’ve always believed in that sense of going beyond and looking where we haven’t looked. I think the film connects that way in a number of different ways. There’s one line I hate and studios love to use: Beyond your imagination. It’s not beyond your imagination. People have great imaginations. They have great dreams when they’re kids. You can fly when you’re a kid in your dreams. As you grow up, your dreams somewhat diminish and you don’t fly as much in your dreams. I wanted to go back to that childlike dream state in this movie because I think we all kind of connect at that level. And so I wanted to create essentially a lucid dream that would connect us all at some kind of unconscious level.”

*     *     *

“We were tasked with designing all these creatures and plants and everything for this movie. And every time we thought we had a great idea somebody would bring in a photograph or some bit of nature here had beat us to the idea. Ultimately, at the end of a two-year design process, we had to just admit with great humility that nature’s imagination was better than the combined imagination of the best visual artists on the planet that I had gathered to make Avatar. And it’s true.”

*     *     *

In his talk at TED 2010, James Cameron “reveals his childhood fascination with the fantastic — from reading science fiction to deep-sea diving — and how it ultimately drove the success of his blockbuster hits Aliens, The Terminator, Titanic and Avatar.”

Painting Has Its Own Inadequacy

The Secretary of State, Luc Tuymans (2005) “What you can do with painting is make a more understated type of imagery that approaches an idea from a different angle. It's another medium, in another timescale. And that produces a cognitive image which is sort of branded in the brain. It has something to do with the idea of remembering the imagery but it's also to do with reconstructing the memory, because memory is something that is completely inadequate. That is where painting also comes in because it has its own inadequacy in that it is never complete.”

Thinking about Calcium Waves in Astrocytes

Excerpts from Andrew Koob’s discussion of glial cells and his related book, The Root of Thought, with Jonah Lehrer in "The Root of Thought: What Do Glial Cells Do?" Scientific American (October 27, 2009):

The Root of Thought: Unlocking Glia- the Brain Cell That Will Help Us Sharpen Our Wits, Heal Injury, and Treat Brain Disease Until the last 20 years, brain scientists believed neurons communicated to each other, represented our thoughts, and that glia were kind of like stucco and mortar holding the house together.  They were considered simple insulators for neuron communication.  There are a few types of glial cells, but recently scientists have begun to focus on a particular type of glial cell called the 'astrocyte,' as they are abundant in the cortex.

Interestingly, as you go up the evolutionary ladder, astrocytes in the cortex increase in size and number, with humans having the most astrocytes and also the biggest.  Scientists have also discovered that astrocytes communicate to themselves in the cortex and are also capable of sending information to neurons. Finally, astrocytes are also the adult stem cell in the brain and control blood flow to regions of brain activity. Because of all these important properties, and since the cortex is believed responsible for higher thought, scientists have started to realize that astrocytes must contribute to thought. 

In short, calcium waves are how astrocytes communicate to themselves. Astrocytes have hundreds of 'endfeet' spreading out from their body. They look like mini octopi, and they link these endfeet with blood vessels, other astrocytes and neuronal synapses. Calcium is released from internal stores in astrocytes as they are stimulated, then calcium travels through their endfeet to other astrocytes. The term 'calcium waves' describes the calcium release and exchange between astrocytes and between astrocytes and neurons.

Glial Cells Scientists at Yale, most notably Ann H. Cornell-Bell and Steven Finkbeiner, have shown that calcium waves can spread from the point of stimulation of one astrocyte to all other astrocytes in an area hundreds of times the size of the original astrocyte (watch video).

Furthermore, calcium waves can also cause neurons to fire. And calcium waves in the cortex are leading scientists to infer that this style of communication may be conducive to the processing of certain thoughts. If that isn't convincing, it was recently shown that a molecule that stimulates the same receptors as THC can ignite astrocyte calcium release. 

This idea [that glia and their calcium waves might play a role in creativity] stems from dreams, sensory deprivation and day dreaming. Without input from our senses through neurons, how is it that we have such vivid thoughts?  How is it that when we are deep in thought we seemingly shut off everything in the environment around us? 

In this theory, neurons are tied to our muscular action and external senses. We know astrocytes monitor neurons for this information. Similarly, they can induce neurons to fire. Therefore, astrocytes modulate neuron behavior.

This could mean that calcium waves in astrocytes are our thinking mind. Neuronal activity without astrocyte processing is a simple reflex; anything more complicated might require astrocyte processing. The fact that humans have the most abundant and largest astrocytes of any animal and we are capable of creativity and imagination also lends credence to this speculation.

Calcium is also released randomly and without stimulation from astrocytes' internal stores in small bursts called 'puffs.'  These random puffs can lead to waves.  It is possible that the seemingly random thoughts during dreams and sensory deprivation experience could be calcium puffs becoming waves in our astrocytes.

Basically, it is obvious that astrocytes are involved in brain processing in the cortex, but the main questions are, do our thoughts and imagination stem from astrocytes working together with neurons, or are our thoughts and imagination solely the domain of astrocytes?  Maybe the role of neurons is to support astrocytes.

Animals Never Lie

Excerpt from White Apples by Jonathan Carroll:

White Apples “Here's something you must know and don't forget it—animals never lie. They don't lie, they don't put on disguises, and they are always true to what they are. That's why you can trust them."

“Excuse me, but I do not trust lions. Or bears or snakes—"

"That’s because you want them to be the creatures you imagined as a child. Lions should be the strong but sweet beasts in a Disney cartoon. But they aren't, so when they start acting like lions you're angry at them for not being the fantasy animals you imagined. Real bears don't wear top hats and ride unicycles. Nor do they sleep in bed next to Goldilocks. Human beings force them to do those stupid things in circuses and films or children's books. Sure, some might be more docile or more ferocious than others, but in the end they will always, always be bears. You know you should never should turn your back on a bear. You should never even get near them; it's that simple. They're not being dishonest—you are in your perception of them."

What We See

Excerpts of dialogue spoken by the Werner Heisenberg character in Michael Frayn’s Tony award winning play, Copenhagen:

How difficult it is to see even what’s in front of one’s eyes. All we possess is the present, and the present endlessly dissolves into the past…And yet how much more difficult still it is to catch the slightest glimpse of what’s behind one’s eyes.

*     *     *

Werner Heisenberg, 1965 BBC interview And that’s when I did uncertainty. Walking round Faelled Park on my own one horrible raw February night. It’s very late, and as soon as I’ve turned off into the park I’m completely alone in the darkness. I start to think about what you’d see, if you could train a telescope on me from the mountains of Norway.

You’d see me by the street lamps on the Blegdamsvej, then nothing as I vanished into the darkness, then another glimpse of me as I passed the lamp-post in front of the bandstand. And that’s what we see in the cloud chamber. Not a continuous track but a series of glimpses — a series of collisions between the passing electron and various molecules of water vapour…

Or think of you, on your great papal progress to Leiden in 1925. What did Margrethe see of that, at home here in Copenhagen? A picture postcard from Hamburg, perhaps. Then one from Leiden. One from Göttingen. One from Berlin. Because what we see in the cloud chamber are not even the collisions themselves, but the water-droplets that condense around them, as big as cities around a traveler — no, vastly bigger still, relatively — complete countries — Germany…Holland…Germany again. There is no track, there are no precise addresses; only a vague list of countries visited. I don’t know why we hadn’t thought of it before, except that we were too busy arguing to think at all.
