Antidotes to Fear of Death: Astrophysicist Janna Levin Reads Astronomer and Poet Rebecca Elson’s Stunning Cosmic Salve for Our Creaturely Tremblings of Heart

“We are all navigating an external world — but only through the prism of our own minds, our own subjective experience… The majesty of the universe is only ever conjured up in the mind.”

Antidotes to Fear of Death: Astrophysicist Janna Levin Reads Astronomer and Poet Rebecca Elson’s Stunning Cosmic Salve for Our Creaturely Tremblings of Heart

It is our biological wiring to exist — and then not; it is our psychological wiring to spend our lives running from this elemental fact on the hamster wheel of busyness and the hedonic treadmill of achievement, running from the disquieting knowledge that the atoms huddling for a cosmic blink around the shadow of a self will one day disband and return to the “aloof stars” that made them. If we still ourselves for a moment, or are bestilled by circumstance, we glimpse that fact, then hasten to avert our gaze. We go on holding it as an abstraction, an unproven theorem; go on casting spells against the proof in stone and wood and promises; go on building houses and egos, signing thirty-year mortgages, trading the forged mint of forever as contractual currency in marital vows. And then one day, some certitude fissures — in the broken surface of a split lip, a split love, a split in Earth’s quaked crust; in the slow-burning wildfire of a pandemic, smoking its way across the globe until it blazes into a shared inferno; in the cold blade of a terminal diagnosis, sudden and close to the bone. We wake up to unalloyed reality with a scream, a silence, a hollow hallelujah.

The astronomer and poet Rebecca Elson (January 2, 1960–May 19, 1999) was twenty-nine when she was diagnosed with non-Hodgkins lymphoma — a blood cancer that typically invades people in their sixties and seventies. Throughout the bodily brutality of the treatment, throughout the haunting uncertainty of life in remission, she met reality on its own terms — reality creaturely and cosmic, terms chance-dealt by impartial laws — and made of that terrifying meeting something uncommonly beautiful.

Rebecca Elson, 1987

When she returned her atoms to the universe, not yet forty, Elson bequeathed to this world 56 scientific papers and a slender, stunning book of poetry titled A Responsibility to Awe (public library) — verses spare and sublime, drawn from a consciousness pulling the balloon string of the infinite through the loop of its own finitude, life-affirming the way only the most intimate contact with death — which means with nature — can be.

Elson’s crowning achievement in verse is the poem “Antidotes to Fear of Death,” beautifully brought to life here as a trailer of sorts for the 2020 Universe in Verse — our annual charitable celebration of the science and splendor of nature through poetry — by astrophysicist, novelist, Pioneer Works Director of Sciences, and devoted enchantress of poetry Janna Levin, with music by cellist, composer, and music revolutionary Zoë Keating based on her original soundtrack for The Edge of All We Know — the forthcoming documentary about the Event Horizon Telescope, which in 2019 captured humanity’s historic first glimpse of a black hole. (Janna works on black holes; Elson was among the select scientists tasked with studying the first images returned by the Hubble Space Telescope, that pioneering emblem of our most ambitious tool-making and our longing for intimate contact with the nature of reality.)

Janna prefaces her reading with a Bohrsian reflection on the relationship between science and poetry, between the objective and the subjective, concluding with an exquisitely insightful and exquisitely phrased observation of how the tension between these seeming dipoles can dissolve upon closer inspection:

We are all navigating an external world — but only through the prism of our own minds, our own subjective experience… The majesty of the universe is only ever conjured up in the mind.

ANTIDOTES TO FEAR OF DEATH
by Rebecca Elson

Sometimes as an antidote
To fear of death,
I eat the stars.

Those nights, lying on my back,
I suck them from the quenching dark
Til they are all, all inside me,
Pepper hot and sharp.

Sometimes, instead, I stir myself
Into a universe still young,
Still warm as blood:

No outer space, just space,
The light of all the not yet stars
Drifting like a bright mist,
And all of us, and everything
Already there
But unconstrained by form.

And sometime it’s enough
To lie down here on earth
Beside our long ancestral bones:

To walk across the cobble fields
Of our discarded skulls,
Each like a treasure, like a chrysalis,
Thinking: whatever left these husks
Flew off on bright wings.

Couple with Regina Spektor reading Elson’s “Theories of Everything” at the 2019 Universe in Verse and Janna reading Maya Angelou’s cosmic clarion call to humanity at the 2018 Universe in Verse, then join us for the livestream of the 2020 show for more beauty and consolation by calibration of perspective, featuring Neil Gaiman premiering another original poem, Patti Smith bringing Emily Dickinson to life, astronaut Leland Melvin reading Neruda’s love letter to Earth’s forests, and thirty other magnificent constellations of atoms celebrating the majesty of the universe and the irreplicable splendor of our Pale Blue Dot.

Stillness as a Form of Action: Tocqueville on Cataclysm as an Antidote to Cultural Complacency and a Catalyst for Growth

“There are periods during which human society seems to rest… This pause is, indeed, only apparent, for time does not stop its course for nations any more than for [individuals]; they are all advancing every day towards a goal with which they are unacquainted.”

Stillness as a Form of Action: Tocqueville on Cataclysm as an Antidote to Cultural Complacency and a Catalyst for Growth

Even when nothing is happening, something is happening. This is a difficult fact for the human animal to fathom — especially for us modern sapiens, who so ardently worship at the altar of productivity and so readily mistake busyness for effectiveness, for propulsion toward progress. Silence is a form of speech, Susan Sontag wrote, “and an element in a dialogue.” Stillness is a form of action and an element in advancement, in evolution, in all forward motion.

There are certain moments, as when winter cusps into spring, when nature itself reminds us of this slippery elemental fact: Buds begin to spine the skeletal silhouettes of trees, withholding leaf and blossom until it is right, until it is safe to spill new life into the chilly air; birds, whose dinosaur bodies have spent all winter preparing to mate, perch silent on the bud-spined branches, all longing and unsung song.

Waiting in the Almost by Maria Popova. Available as a print.

There are certain moments in culture, too, when we must especially remember, in order to stay sane, this slippery elemental fact.

Those moments and their neglected significance are what Alexis de Tocqueville (July 29, 1805–April 16, 1859) explores in a brief, intensely insightful passage from his 1835 classic Democracy in America (public library).

Since Tocqueville belongs to the long stretch of epochs predating Ursula K. Le Guin’s brilliant unsexing of the universal pronoun, I have taken the liberty (a liberty I very rarely take with historical texts, for it is often ahistorical to take it, but one that feels right in this case) of rehumanizing his men as individuals and people. He writes:

At certain periods a nation may be oppressed by such insupportable evils as to conceive the design of effecting a total change in its political constitution; at other times… the existence of society itself is endangered. Such are the times of great revolutions… But between these epochs of misery and confusion there are periods during which human society seems to rest and mankind to take breath. This pause is, indeed, only apparent, for time does not stop its course for nations any more than for [individuals]; they are all advancing every day towards a goal with which they are unacquainted.

In an analogy the physical fact of which would become the basis of Einstein’s epoch-making development of relativity many decades later, Tocqueville adds:

We imagine them to be stationary only when their progress escapes our observation, as [people] who are walking seem to be standing still to those who run.

Art by Cindy Derby from A Velocity of Being: Letters to a Young Reader. Available as a print.

Because this transformative stillness is so imperceptible, Tocqueville observes, and because it appears after periods of upheaval, we are apt to mistake the stillness for an end point. Nearly two centuries before psychologist Daniel Gilbert quipped that “human beings are works in progress that mistakenly think they’re finished” in his excellent inquiry into how our present illusions hinder our future happiness, Tocqueville admonishes against this illusion of finality, as true on the scale of individuals as it is on the scale of societies, nations, and civilizations:

There are certain epochs in which the changes that take place in the social and political constitution of nations are so slow and imperceptible that [people] imagine they have reached a final state; and the human mind, believing itself to be firmly based upon sure foundations, does not extend its researches beyond a certain horizon.

The great gift of such periods is that they invite us to question our certitudes, our givens, these seemingly sure foundations that have lulled us into complacency — for it is only by being jolted out of our complacencies, cultural or personal, that we ever reach beyond the horizon, toward new territories of truth, beauty, and flourishing.

Complement with Thoreau on the long cycles of change, Hannah Arendt on small action as the fulcrum of our humanity, and a wonderful modern meditation on the art of waiting in an impatient culture, then revisit Pico Iyer on what Leonard Cohen taught him about the art of stillness and Pablo Neruda’s timeless ode to silence.

This Is Chance: The Story of the 1964 Alaska Earthquake and the Remarkable Woman Who Magnetized People into Falling Together as Their World Fell Apart

“What is safety, anyway? How can you predict where or when tragedy will occur? You can only learn to live with it and make the best of it when it happens.”

This Is Chance: The Story of the 1964 Alaska Earthquake and the Remarkable Woman Who Magnetized People into Falling Together as Their World Fell Apart

We might spend our lives trying to discern where we end and the rest of the world begins, but we save them by experiencing ourselves — our selves, each individual self — as “the still point of the turning world,” to borrow T.S. Eliot’s lovely phrase from one of the greatest poems ever written. And yet that point is pinned to a figment — our fundamental creaturely sense of reality is founded upon the illusion of absolute rest.

On March 27, 1964 — Good Friday — thousands of selves in Anchorage, Alaska came unpinned from their most elemental certitudes about reality, about safety, about the thousand small sanities by which we bestill this turning world to make it livable.

At 5:36PM, as the afternoon sun was slipping lazily toward the horizon — that quiet daily assurance that the Earth moves intact on its steady axis along its unfaltering orbital path — street lights began swaying, then flying. The pavement beneath them accordioned, then gaped open, swallowing cars and spitting them back up. Walls came unseamed and reseamed before disbelieving eyes that had not yet computed, for it was beyond the computational power of everyday consciousness, what was taking place.

Buildings rippled “up and down in sections, just like a caterpillar,” in one observer’s recollection, before ripping apart and crumbling completely like the brittle simulacra of safety that buildings are. Inside them, books toppled from their shelves to take rapid turns levitating from the floor, flames engulfed school science labs as chemicals crumpled together, and cast-iron pots of moose stew jumped off kitchen stoves.

The city’s electric grid was snapped and uprooted — in the below-freezing cold, in the descending dusk, all power went out.

When people tried running for their lives, they found their basic biped function furloughed — the Earth hurled each step back at them, tossing their center of gravity like a marble around a child’s cupped hand.

Water levels jumped as far away as South Africa. I picture my grandparents’ well in Bulgaria undulating in the middle of the night as they slept heavily under their Rhodope wool blankets, having celebrated my mother’s second birthday in the hours before Anchorage came unborn.

At 9.2 on the Richter Scale, the earthquake was more powerful than any previously measured — so violent that, as one seismologist phrased it, “it made the earth ring like a bell.” Just as the collision of two black holes ripples the fabric of spacetime with such brutality that it rings a gravitational wave, two tectonic plates had been in slow-motion collision for millennia, building up pressure that finally, on that early-spring afternoon, rang the planet itself and discomposed Anchorage into a level of trauma that would devastate the community, then jolt it into discovering its own entirely unfathomed wellsprings of resilience, solidarity, and generosity.

Driving to the local bookstore with one of her three children was a woman who would emerge as the unlikely hero not only of the community’s survival but of its transformation through tragedy. As their world fell apart, she would magnetize people into falling together.

Genie Chance (January 24, 1927–May 17, 1998) is the protagonist of Jon Mooallem’s uncommonly wonderful book This Is Chance!: The Shaking of an All-American City, A Voice That Held It Together (public library). Driving the heart of this scrupulously researched and sensitively told story about a singular event at a particular time in a particular place is the timeless, universal pulse-beat of assurance, suddenly rendered timely to the point of prophetic — the assurance that comes from the lived record of communities surviving cataclysms even more savaging than our own and emerging from them stronger, more closely knit, more human.

In 1964, Anchorage had barely nursed its first generation of city-born citizens and Alaska itself had only just become a state five years earlier. The town existed, Mooallem writes, as “a blotch of Western civilization in the middle of emptiness,” on a patch of land “often disregarded as a kind of free-floating addendum to the rest of America.” Culture itself was in a state of disorientation — months earlier, JFK’s assassination and The Feminine Mystique had shaken the world with their respective dissolutions of certitudes. Anchorage was hungry to pin itself on the map, to self-create an identity and then to assert it with the fiery impatience of a teenager undergoing the developmental stage of individuation — a city that, in one visitor’s account, “reached aggressively and greedily to grasp the future, impatient with any suggestion that such things take time.” Mooallem writes:

That determination made it difficult for those who lived in Anchorage to recognize how indifferently the city they were building could be knocked down — to imagine that, early one Friday evening, the very ground beneath them might rear up and shake their town like “a dog shaking an animal he’s killed,” as one man later described it. Even while the earth was moving, the ferocious strangeness of what was happening to Anchorage was hard for people to internalize or accept. Buildings keeled off their foundations, slumped in on themselves, split in half or sunk. Four-foot-high ground waves rolled through the roads as though the pavement were liquid. A city of infallible right angles buckled and bent.

It wasn’t as though, before the quake, people in Anchorage pictured these things happening and dismissed them as impossible; they just never pictured them. They couldn’t. More to the point: Why would they? Like all of us, they looked around and registered what they saw as stable and permanent: a world that just was.

But there are moments when the world we take for granted instantaneously changes; when reality is abruptly upended and the unimaginable overwhelms real life. We don’t walk around thinking about that instability, but we know it’s always there: at random, and without warning, a kind of terrible magic can switch on and scramble our lives.

When the earthquake churned its terrible magic over Anchorage, Genie Chance — who described herself as “one of those people with an insatiable curiosity who wants to understand in depth what someone else is doing, thinking, or talking about” — was working as a part-time reporter for the local radio station, KENI. Part-time but triple-throttle: When she wasn’t racing on her daily rounds to the police station and the courthouse to report on local crime and punishment, she flew with the air patrol on wilderness rescue missions, trailed army units during Arctic training exercises, captured life on crab boats and in Inuit villages, forewitnessed death on nuclear missile testing sites, and had to be dissuaded from climbing a fire ladder with her tape recorder during a building fire while she was recovering from pneumonia.

All of this she did before rushing home to make dinner for her three children and their father. But she inhabited these two radically different worlds as one extraordinary, integrated self — “a woman who bore the conspicuous burden of always being fully and unflaggingly herself,” in Mooallem’s lovely phrasing — a self outside its time and place, for being a working mother rather than a housewife was already countercultural enough, but being a working mother of unstoppable ambition covered her path with the shrapnel of shock and the indictments of arrogance with which women’s confident competence is often repudiated.

She was the only female newscaster in the state and little seemed to have changed in the century-some since Margaret Fuller became America’s first female news correspondent during a major upheaval as she was paving the way for what we now call feminism. Once, after Genie spent three days reporting on the search effort for a major airplane crash off the coast of Alaska, NBC’s national newscast came calling for her coverage, but requested that a man be sent to redo all of her interviews for a more authoritative air on the air. But her persistent dedication to this essential community-building work soon eclipsed the dismissal and established her as the trusted voice on the radio — trust that threaded the community as a lifetime in the wake of the catastrophe, as fifty-two aftershocks shook the city after the initial rupture. Mooallem writes:

As Anchorage staggered to its feet, each person, or cluster of people, was cut off from everyone else. There was no way to know exactly what had happened, or how thoroughly their world had been jumbled.

This feeling of vulnerability saturated the city. One man, discovering he’d fallen to the sandy bottom of a pit, explained, “You just wonder, ‘Where are you?’ You don’t know if anybody else is alive. Maybe you’re the last man.” Another remembered taking stock of the erratic transfiguration of his neighborhood and assuming that no other part of Anchorage could possibly have gotten hit so badly. Others made the opposite assumption: that the devastation they couldn’t see must be far worse. Both assumptions provoked loneliness. Each generated a slightly different species of despair.

It was reassuring, then, to hear another voice on the radio, talking to you — especially a familiar voice like Genie’s. It urged your imagination outward, encouraged you to picture other people, still out there, listening to the radio, too.

That voice had risked her own life in the determination to serve — having ensured her family’s safety, she had raced back downtown as buildings collapsed around her to assess what was actually going on and how she could help. She had seen things one never forgets — incomprehensible objects that mere hours ago had been bodies animated by human lives and loves and favorite songs — and she had discerned her task: to inform without alarming, to comfort without deluding, to be the steady hand in the small of the back guiding the buckle-kneed and the disoriented survivors toward safety, toward sanity, toward some version of sense-making amid the senseless ruin of their reality.

Genie Chance quickly grasped what our modern media have failed to grasp again and again in times of crisis: that past a certain tipping point of quantity, past a certain threshold of reliability, past a certain pitch level of delivery, facts cease to constellate into information and instead become slippery corpuscles saturating a fog of fright. Genie Chance’s job was choice — she had to perform that taxing calculus of moral judgment, that ultimate curatorial task of choosing what facts to broadcast and what to withhold in order to render people maximally equipped to protect themselves and minimally inclined toward panic, which she knew would hinder all rescue and recovery efforts in what was going to be days, weeks, possibly months of people trapped together in a crippled city. “Mass hysteria would have meant total destruction,” she would later recount.

Stationing herself at Anchorage’s Public Safety Building as night fell on the powerless city, she began working with the police chief, the fire chief, and various officials. As soon as KENI was back on the air with a generator, she began broadcasting the essentials of survival: where to take shelter, how to purify snow for drinking water. She instructed people to limit the use of candles to the bare minimum of necessity — candles were a fire hazard, the city had just evaded a conflagration by what seemed like a miracle, and the water supply system was too savaged to fight a fire outbreak.

She then began collating eyewitness accounts to give people an accurate picture of what had just unworlded them, careful to convey the gravity of the situation without details so gruesome that people would lose hope, still performing the impossible informational acrobatics at the balance-point on the beam between paralysis and panic. Mooallem writes:

Information was a form of comfort. Each stunned, eye-witness account on the radio that night appeared to help people in Anchorage find the contours of this sinister abstraction they were living through — and to locate their places in it.

Within hours, Genie Chance had become the city’s first public information officer. But she soon became something more. Distressed people began turning up at her makeshift desk, bearing the impossible weight of not knowing whether their loved ones were dead or alive. Recognizing the psychological emergency beyond the physical first aid, Genie Chance became the human hub of a vast network of need and began broadcasting these trembling-hearted messages.

“A message to Clyde Wythe at Homer: Your daughter is OK.”

“We have received a call from Joe Fernbeck who said that he’d gotten word on his radio from the oil crews at Beluga and Tyonek. They want their families to know that they are all OK.”

“We have a message reporting that an elderly lady at 216 East Eighth Avenue who lives alone. We have no name on her, but we do have a request for somebody in that neighborhood to please check and see if the sweet lady is all right.”

Mooallem writes:

You could hear the potential death toll in the city gradually ticking down. And with each small declaration of survival that aired, you could imagine a constellation of affirming flames slowly lighting the emptiness outside.

The words of one listener from the remote community of Clam Gulch bellow across space, time, and situation with especially poignancy and relevance today:

It made us who were fortunate realize that no matter what powerful forces nature unleashes, it also releases similar forces in our men and women to cope with them.

By Monday, as Anchorage began stumbling to its feet amid heavy snow and below-freezing temperatures, Genie Chance observed from the airwaves:

Tension is showing on the faces of a proud people. The realization that the Good Friday earthquake will have long-range repercussions on the entire state is beginning to strike at their hearts.

She took it upon herself to steady those hearts. How she did that — how she was in a position to help in the first place, having risen in radio across the personal abyss of depression and the cultural barriers of sexism; how her public service paved the way for her election to the Alaska Senate; how it illuminated what Martin Luther King, Jr. had so poetically termed a year earlier our “inescapable network of mutuality” and how it still illuminates the timeless centripetal forces holding communities together into something larger and more alive than coexisting individuals — that and a great, largehearted deal more is what Mooallem explores in the rest of This Is Chance!, which he ends with a gorgeous glimpse of Genie Chance’s animating spirit.

The week following the earthquake, when her mother wrote from Texas beseeching her to send the children there for safety, Genie had a decision to make — a decision that might have appeared simple to a person of less penetrating vision into the innermost pillars of survival. Beneath that surface simplicity, which rests upon a view of safety as physical security, Genie Chance fathomed the layers of complexity: The very notion of physical security had just been unmasked as an illusion in the first place, in any place; but beneath it, she suddenly saw, there lay a stratum of psychological and emotional security from which we mine the building blocks of our only reliable human shelter. She wrote back to her mother:

I must admit that during that first dark, cold night, as I began to understand the tremendous scope of the problems that would be facing us in the months and years to come, I toyed with the idea of sending the children out on a plane to stay with you until everything settled down. Working there in the headquarters, where the reports were coming in from the survey teams throughout the city, I realized that there could possibly be a real health hazard for some time to come. I realized that the schools might not be able to resume for an indefinite period of time. It looked for a few hours as if the damage had been so extensive to all utilities and streets that even a semblance of normal life could not be resumed for weeks or months.

[…]

But this was just a fleeting thought in a weary mind. I would have been ashamed of myself had it not been for the next thought that came so swiftly: We must be together… That night I saw strain, heavy hearts, and fear in people separated from their loved ones by the sudden disaster… As long as we are together, we are confident of the future…

That Good Friday night I knew that we had survived miraculously. And for this reason, there must be a purpose to our lives. Apparently the children must sense this, too. For they have remained calm. They have been fully aware of the emergency, but they have not feared. We are proud that they are such dependable, responsible youngsters. I would not undermine their confidence in the future — in themselves — by sending them away for safety.

What is safety, anyway? How can you predict where or when tragedy will occur? You can only learn to live with it and make the best of it when it happens. These children have learned this — and they are all the better for it. They were in the midst of devastation. And they feel that they are a part of the tremendous task ahead in rebuilding this land we love… The children are not afraid. Their father and I are not afraid. Please, don’t you fear for us.

Mooallem — who previously composed the beautiful, bittersweet, and surprisingly buoyant ecological elegy Wild Ones — reflects on the disquieting confrontation with the nature of reality that the earthquake thrust upon the world it shattered, and wrests from the disquietude the kernel of a larger truth that makes reality not only bearable but beautiful:

What is safety, anyway? Genie seemed to be conceding how randomly our lives are jostled and spun around; that nothing is fixed; that even the ground we stand on is in motion. Underneath us, there is only instability. Beyond us, there’s only chance.

But she’d also recognized a way of surviving such a world. It was what Genie had created in Anchorage that weekend by talk- ing on the radio, and what she planned to stay focused on now: not an antidote to that unpredictability, exactly, but at least a strategy for withstanding it, for wringing meaning from a life we know to be unsteady and provisional. The best she and her family could do was to hold on to one another.

Our force for counteracting chaos is connection.

How Kepler Invented Science Fiction and Defended His Mother in a Witchcraft Trial While Revolutionizing Our Understanding of the Universe

How many revolutions does the cog of culture make before a new truth about reality catches into gear?

This essay is adapted from Figuring.

This is how I picture it:

A spindly middle-aged mathematician with a soaring mind, a sunken heart, and bad skin is being thrown about the back of a carriage in the bone-hollowing cold of a German January. Since his youth, he has been inscribing into family books and friendship albums his personal motto, borrowed from a verse by the ancient poet Perseus: “O the cares of man, how much of everything is futile.” He has weathered personal tragedies that would level most. He is now racing through the icy alabaster expanse of the countryside in the precarious hope of averting another: Four days after Christmas and two days after his forty-fourth birthday, a letter from his sister has informed him that their widowed mother is on trial for witchcraft — a fact for which he holds himself responsible.

He has written the world’s first work of science fiction — a clever allegory advancing the controversial Copernican model of the universe, describing the effects of gravity decades before Newton formalized it into a law, envisioning speech synthesis centuries before computers, and presaging space travel three hundred years before the Moon landing. The story, intended to counter superstition with science through symbol and metaphor inviting critical thinking, has instead effected the deadly indictment of his elderly, illiterate mother.

The year is 1617. His name is Johannes Kepler (December 27, 1571–November 15, 1630) — perhaps the unluckiest man in the world, perhaps the greatest scientist who ever lived.

Johannes Kepler

He inhabits a world in which God is mightier than nature, the Devil realer and more omnipresent than gravity. All around him, people believe that the sun revolves around the Earth every twenty-four hours, set into perfect circular motion by an omnipotent creator; the few who dare support the tendentious idea that the Earth rotates around its axis while revolving around the sun believe that it moves along a perfectly circular orbit. Kepler would disprove both beliefs, coin the word orbit, and quarry the marble out of which classical physics would be sculpted. He would be the first astronomer to develop a scientific method of predicting eclipses and the first to link mathematical astronomy to material reality — the first astrophysicist — by demonstrating that physical forces move the heavenly bodies in calculable ellipses. All of this he would accomplish while drawing horoscopes, espousing the spontaneous creation of new animal species rising from bogs and oozing from tree bark, and believing the Earth itself to be an ensouled body that has digestion, that suffers illness, that inhales and exhales like a living organism. Three centuries later, the marine biologist and writer Rachel Carson would reimagine a version of this view woven of science and stripped of mysticism as she makes ecology a household word.

Kepler’s life is a testament to how science does for reality what Plutarch’s thought experiment known as “the Ship of Theseus” does for the self. In the ancient Greek allegory, Theseus — the founder-king of Athens — sailed triumphantly back to the great city after slaying the mythic Minotaur on Crete. For a thousand years, his ship was maintained in the harbor of Athens as a living trophy and was sailed to Crete annually to reenact the victorious voyage. As time began to corrode the vessel, its components were replaced one by one — new planks, new oars, new sails — until no original part remained. Was it then, Plutarch asks, the same ship? There is no static, solid self. Throughout life, our habits, beliefs, and ideas evolve beyond recognition. Our physical and social environments change. Almost all of our cells are replaced. Yet we remain, to ourselves, “who” “we” “are.”

So with science: Bit by bit, discoveries reconfigure our understanding of reality. This reality is revealed to us only in fragments. The more fragments we perceive and parse, the more lifelike the mosaic we make of them. But it is still a mosaic, a representation — imperfect and incomplete, however beautiful it may be, and subject to unending transfiguration. Three centuries after Kepler, Lord Kelvin would take the podium at the British Association of Science in the year 1900 and declare: “There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.” At the same moment in Zurich, the young Albert Einstein is incubating the ideas that would converge into his revolutionary conception of spacetime, irreversibly transfiguring our elemental understanding of reality.

Even the farthest seers can’t bend their gaze beyond their era’s horizon of possibility, but the horizon shifts with each incremental revolution as the human mind peers outward to take in nature, then turns inward to question its own givens. We sieve the world through the mesh of these certitudes, tautened by nature and culture, but every once in a while — whether by accident or conscious effort — the wire loosens and the kernel of a revolution slips through.

Painting of the Moon by the 17th-century German self-taught astronomer and artist Maria Clara Eimmart. (Available as a print.)

Kepler first came under the thrall of the heliocentric model as a student at the Lutheran University of Tübingen half a century after Copernicus published his theory. The twenty-two-year-old Kepler, studying to enter the clergy, wrote a dissertation about the Moon, aimed at demonstrating the Copernican claim that the Earth is moving simultaneously around its axis and around the sun. A classmate by the name of Christoph Besold — a law student at the university — was so taken with Kepler’s lunar paper that he proposed a public debate. The university promptly vetoed it. A couple of years later, Galileo would write to Kepler that he’d been a believer in the Copernican system himself “for many years” — and yet he hadn’t yet dared to stand up for it in public and wouldn’t for more than thirty years.

Kepler’s radical ideas rendered him too untrustworthy for the pulpit. After graduation, he was banished across the country to teach mathematics at a Lutheran seminary in Graz. But he was glad — he saw himself, mind and body, as cut out for scholarship. “I take from my mother my bodily constitution,” he would later write, “which is more suited to study than to other kinds of life.” Three centuries later, Walt Whitman would observe how beholden the mind is to the body, “how behind the tally of genius and morals stands the stomach, and gives a sort of casting vote.”

While Kepler saw his body as an instrument of scholarship, other bodies around him were being exploited as instruments of superstition. In Graz, he witnessed dramatic exorcisms performed on young women believed to be possessed by demons — grim public spectacles staged by the king and his clergy. He saw brightly colored fumes emanate from one woman’s belly and glistening black beetles crawl out of another’s mouth. He saw the deftness with which the puppeteers of the populace dramatized dogma to wrest control — the church was then the mass media, and the mass media were as unafraid of resorting to propaganda as they are today.

As religious persecution escalated — soon it would erupt into the Thirty Years’ War, the deadliest religious war in the Continent’s history — life in Graz became unlivable. Protestants were forced to marry by Catholic ritual and have their children baptized as Catholics. Homes were raided, heretical books confiscated and destroyed. When Kepler’s infant daughter died, he was fined for evading the Catholic clergy and not allowed to bury his child until he paid the charge. It was time to migrate — a costly and trying endeavor for the family, but Kepler knew there would be a higher price to pay for staying:

I may not regard loss of property more seriously than loss of opportunity to fulfill that for which nature and career have destined me.

Returning to Tübingen for a career in the clergy was out of the question:

I could never torture myself with greater unrest and anxiety than if I now, in my present state of conscience, should be enclosed in that sphere of activity.

Instead, Kepler reconsidered something he had initially viewed merely as a flattering compliment to his growing scientific reputation: an invitation to visit the prominent Danish astronomer Tycho Brahe in Bohemia, where he had just been appointed royal mathematician to the Holy Roman Emperor.

Tycho Brahe

Kepler made the arduous five-hundred-kilometer journey to Prague. On February 4, 1600, the famous Dane welcomed him warmly into the castle where he computed the heavens, his enormous orange mustache almost aglow with geniality. During the two months Kepler spent there as guest and apprentice, Tycho was so impressed with the young astronomer’s theoretical ingenuity that he permitted him to analyze the celestial observations he had been guarding closely from all other scholars, then offered him a permanent position. Kepler accepted gratefully and journeyed back to Graz to collect his family, arriving in a retrograde world even more riven by religious persecution. When the Keplers refused to convert to Catholicism, they were banished from the city — the migration to Prague, with all the privations it would require, was no longer optional. Shortly after Kepler and his family alighted in their new life in Bohemia, the valve between chance and choice opened again, and another sudden change of circumstance flooded in: Tycho died unexpectedly at the age of fifty-four. Two days later, Kepler was appointed his successor as imperial mathematician, inheriting Tycho’s data. Over the coming years, he would draw on it extensively in devising his three laws of planetary motion, which would revolutionize the human understanding of the universe.

How many revolutions does the cog of culture make before a new truth about reality catches into gear?

Three centuries before Kepler, Dante had marveled in his Divine Comedy at the new clocks ticking in England and Italy: “One wheel moves and drives the other.” This marriage of technology and poetry eventually gave rise to the metaphor of the clockwork universe. Before Newton’s physics placed this metaphor at the ideological epicenter of the Enlightenment, Kepler bridged the poetic and the scientific. In his first book, The Cosmographic Mystery, Kepler picked up the metaphor and stripped it of its divine dimensions, removing God as the clockmaster and instead pointing to a single force operating the heavens: “The celestial machine,” he wrote, “is not something like a divine organism, but rather something like a clockwork in which a single weight drives all the gears.” Within it, “the totality of the complex motions is guided by a single magnetic force.” It was not, as Dante wrote, “love that moves the sun and other stars” — it was gravity, as Newton would later formalize this “single magnetic force.” But it was Kepler who thus formulated for the first time the very notion of a force — something that didn’t exist for Copernicus, who, despite his groundbreaking insight that the sun moves the planets, still conceived of that motion in poetic rather than scientific terms. For him, the planets were horses whose reins the sun held; for Kepler, they were gears the sun wound by a physical force.

In the anxious winter of 1617, unfigurative wheels are turning beneath Johannes Kepler as he hastens to his mother’s witchcraft trial. For this long journey by horse and carriage, Kepler has packed a battered copy of Dialogue on Ancient and Modern Music by Vincenzo Galilei, his sometime friend Galileo’s father — one of the era’s most influential treatises on music, a subject that always enchanted Kepler as much as mathematics, perhaps because he never saw the two as separate. Three years later, he would draw on it in composing his own groundbreaking book The Harmony of the World, in which he would formulate his third and final law of planetary motion, known as the harmonic law — his exquisite discovery, twenty-two years in the making, of the proportional link between a planet’s orbital period and the length of the axis of its orbit. It would help compute, for the first time, the distance of the planets from the sun — the measure of the heavens in an era when the Solar System was thought to be all there was.

As Kepler is galloping through the German countryside to prevent his mother’s execution, the Inquisition in Rome is about to declare the claim of Earth’s motion heretical — a heresy punishable by death.

Behind him lies a crumbled life: Emperor Rudolph II is dead — Kepler is no longer royal mathematician and chief scientific adviser to the Holy Roman Emperor, a job endowed with Europe’s highest scientific prestige, though primarily tasked with casting horoscopes for royalty; his beloved six-year-old son is dead — “a hyacinth of the morning in the first day of spring” wilted by smallpox, a disease that had barely spared Kepler himself as a child, leaving his skin cratered by scars and his eyesight permanently damaged; his first wife is dead, having come unhinged by grief before succumbing to the pox herself.

Before him lies the collision of two worlds in two world systems, the spark of which would ignite the interstellar imagination.

In 1609, Johannes Kepler finished the first work of genuine science fiction — that is, imaginative storytelling in which sensical science is a major plot device. Somnium, or The Dream, is the fictional account of a young astronomer who voyages to the Moon. Rich in both scientific ingenuity and symbolic play, it is at once a masterwork of the literary imagination and an invaluable scientific document, all the more impressive for the fact that it was written before Galileo pointed the first spyglass at the sky and before Kepler himself had ever looked through a telescope.

Kepler knew what we habitually forget — that the locus of possibility expands when the unimaginable is imagined and then made real through systematic effort. Centuries later, in a 1971 conversation with Carl Sagan and Arthur C. Clarke about the future of space exploration, science fiction patron saint Ray Bradbury would capture this transmutation process perfectly: “It’s part of the nature of man to start with romance and build to a reality.” Like any currency of value, the human imagination is a coin with two inseparable sides. It is our faculty of fancy that fills the disquieting gaps of the unknown with the tranquilizing certitudes of myth and superstition, that points to magic and witchcraft when common sense and reason fail to unveil causality. But that selfsame faculty is also what leads us to rise above accepted facts, above the limits of the possible established by custom and convention, and reach for new summits of previously unimagined truth. Which way the coin flips depends on the degree of courage, determined by some incalculable combination of nature, culture, and character.

In a letter to Galileo containing the first written mention of The Dream’s existence and penned in the spring of 1610 — a little more than a century after Columbus voyaged to the Americas — Kepler ushers his correspondent’s imagination toward fathoming the impending reality of interstellar travel by reminding him just how unimaginable transatlantic travel had seemed not so long ago:

Who would have believed that a huge ocean could be crossed more peacefully and safely than the narrow expanse of the Adriatic, the Baltic Sea or the English Channel?

Kepler envisions that once “sails or ships fit to survive the heavenly breezes” are invented, voyagers would no longer fear the dark emptiness of interstellar space. With an eye to these future explorers, he issues a solidary challenge:

So, for those who will come shortly to attempt this journey, let us establish the astronomy: Galileo, you of Jupiter, I of the moon.

Newton would later refine Kepler’s three laws of motion with his formidable calculus and richer understanding of the underlying force as the foundation of Newtonian gravity. In a quarter millennium, the mathematician Katherine Johnson would draw on these laws in computing the trajectory that lands Apollo 11 on the Moon. They would guide the Voyager spacecraft, the first human-made object to sail into interstellar space.

In The Dream, which Kepler described in his letter to Galileo as a “lunar geography,” the young traveler lands on the Moon to find that lunar beings believe Earth revolves around them — from their cosmic vantage point, our pale blue dot rises and sets against their firmament, something reflected even in the name they have given Earth: Volva. Kepler chose the name deliberately, to emphasize the fact of Earth’s revolution — the very motion that made Copernicanism so dangerous to the dogma of cosmic stability. Assuming that the reader is aware that the Moon revolves around the Earth — an anciently observed fact, thoroughly uncontroversial by his day — Kepler intimates the unnerving central question: Could it be, his story suggests in a stroke of allegorical genius predating Edwin Abbott Abbott’s Flatland by nearly three centuries, that our own certitude about Earth’s fixed position in space is just as misguided as the lunar denizens’ belief in Volva’s revolution around them? Could we, too, be revolving around the sun, even though the ground feels firm and motionless beneath our feet?

The Dream was intended to gently awaken people to the truth of Copernicus’s disconcerting heliocentric model of the universe, defying the long-held belief that Earth is the static center of an immutable cosmos. But earthlings’ millennia-long slumber was too deep for The Dream — a deadly somnolence, for it resulted in Kepler’s elderly mother’s being accused of witchcraft. Tens of thousands of people would be tried for witchcraft by the end of the persecution in Europe, dwarfing the two dozen who would render Salem synonymous with witchcraft trials seven decades later. Most of the accused were women, whose inculpation or defense fell on their sons, brothers, and husbands. Most of the trials ended in execution. In Germany, some twenty-five thousand were killed. In Kepler’s sparsely populated hometown alone, six women had been burned as witches just a few weeks before his mother was indicted.

An uncanny symmetry haunts Kepler’s predicament — it was Katharina Kepler who had first enchanted her son with astronomy when she took him to the top of a nearby hill and let the six-year-old boy gape in wonderment as the Great Comet of 1577 blazed across the sky.

By the time he wrote The Dream, Kepler was one of the most prominent scientists in the world. His rigorous fidelity to observational data harmonized with a symphonic imagination. Drawing on Tycho’s data, Kepler devoted a decade and more than seventy failed trials to calculating the orbit of Mars, which became the yardstick for measuring the heavens. Having just formulated the first of his laws, demolishing the ancient belief that the heavenly bodies obey uniform circular motion, Kepler demonstrated that the planets orbit the sun at varying speeds along ellipses. Unlike previous models, which were simply mathematical hypotheses, Kepler discovered the actual orbit by which Mars moved through space, then used the Mars data to determine Earth’s orbit. Taking multiple observations of Mars’s position relative to Earth, he examined how the angle between the two planets changed over the course of the orbital period he had already calculated for Mars: 687 days. To do this, Kepler had to project himself onto Mars with an empathic leap of the imagination. The word empathy would come into popular use three centuries later, through the gateway of art, when it entered the modern lexicon in the early twentieth century to describe the imaginative act of projecting oneself into a painting in an effort to understand why art moves us. Through science, Kepler had projected himself into the greatest work of art there is in an effort to understand how nature draws its laws to move the planets, including the body that moves us through space. Using trigonometry, he calculated the distance between Earth and Mars, located the center of Earth’s orbit, and went on to demonstrate that all the other planets also moved along elliptical orbits, thus demolishing the foundation of Greek astronomy — uniform circular motion — and effecting a major strike against the Ptolemaic model.

Kepler published these revelatory results, which summed up his first two laws, in his book Astronomia nova — The New Astronomy. That is exactly what it was — the nature of the cosmos had forever changed, and so had our place in it. “Through my effort God is being celebrated in astronomy,” Kepler wrote to his former professor, reflecting on having traded a career in theology for the conquest of a greater truth.

By the time of Astronomia nova, Kepler had ample mathematical evidence affirming Copernicus’s theory. But he realized something crucial and abiding about human psychology: The scientific proof was too complex, too cumbersome, too abstract to persuade even his peers, much less the scientifically illiterate public; it wasn’t data that would dismantle their celestial parochialism, but storytelling. Three centuries before the poet Muriel Rukeyser wrote that “the universe is made of stories, not of atoms,” Kepler knew that whatever the composition of the universe may be, its understanding was indeed the work of stories, not of science — that what he needed was a new rhetoric by which to illustrate, in a simple yet compelling way, that the Earth is indeed in motion. And so The Dream was born.

Even in medieval times, the Frankfurt Book Fair was one of the world’s most fecund literary marketplaces. Kepler attended it frequently in order to promote his own books and to stay informed about other important scientific publications. He brought the manuscript of The Dream with him to this safest possible launchpad, where the other attendees, in addition to being well aware of the author’s reputation as a royal mathematician and astronomer, were either scientists themselves or erudite enough to appreciate the story’s clever allegorical play on science. But something went awry: Sometime in 1611, the sole manuscript fell into the hands of a wealthy young nobleman and made its way across Europe. By Kepler’s account, it even reached John Donne and inspired his ferocious satire of the Catholic Church, Ignatius His Conclave. Circulated via barbershop gossip, versions of the story had reached minds far less literary, or even literate, by 1615. These garbled retellings eventually made their way to Kepler’s home duchy.

“Once a poem is made available to the public, the right of interpretation belongs to the reader,” young Sylvia Plath would write to her mother three centuries later. But interpretation invariably reveals more about the interpreter than about the interpreted. The gap between intention and interpretation is always rife with wrongs, especially when writer and reader occupy vastly different strata of emotional maturity and intellectual sophistication. The science, symbolism, and allegorical virtuosity of The Dream were entirely lost on the illiterate, superstitious, and vengeful villagers of Kepler’s hometown. Instead, they interpreted the story with the only tool at their disposal — the blunt weapon of the literal shorn of context. They were especially captivated by one element of the story: The narrator is a young astronomer who describes himself as “by nature eager for knowledge” and who had apprenticed with Tycho Brahe. By then, people far and wide knew of Tycho’s most famous pupil and imperial successor. Perhaps it was a point of pride for locals to have produced the famous Johannes Kepler, perhaps a point of envy. Whatever the case, they immediately took the story to be not fiction but autobiography. This was the seedbed of trouble: Another main character was the narrator’s mother — an herb doctor who conjures up spirits to assist her son in his lunar voyage. Kepler’s own mother was an herb doctor.

Whether what happened next was the product of intentional malevolent manipulation or the unfortunate workings of ignorance is hard to tell. My own sense is that one aided the other, as those who stand to gain from the manipulation of truth often prey on those bereft of critical thinking. According to Kepler’s subsequent account, a local barber overheard the story and seized upon the chance to cast Katharina Kepler as a witch — an opportune accusation, for the barber’s sister Ursula had a bone to pick with the elderly woman, a disavowed friend. Ursula Reinhold had borrowed money from Katharina Kepler and never repaid it. She had also confided in the old widow about having become pregnant by a man other than her husband. In an act of unthinking indiscretion, Katharina had shared this compromising information with Johannes’s younger brother, who had then just as unthinkingly circulated it around the small town. To abate scandal, Ursula had obtained an abortion. To cover up the brutal corporeal aftermath of this medically primitive procedure, she blamed her infirmity on a spell — cast against her, she proclaimed, by Katharina Kepler. Soon Ursula persuaded twenty-four suggestible locals to give accounts of the elderly woman’s sorcery — one neighbor claimed that her daughter’s arm had grown numb after Katharina brushed against it in the street; the butcher’s wife swore that pain pierced her husband’s thigh when Katharina walked by; the limping schoolmaster dated the onset of his disability to a night ten years earlier when he had taken a sip from a tin cup at Katharina’s house while reading her one of Kepler’s letters. She was accused of appearing magically through closed doors, of having caused the deaths of infants and animals. The Dream, Kepler believed, had furnished the superstition-hungry townspeople with evidence of his mother’s alleged witchcraft — after all, her own son had depicted her as a sorcerer in his story, the allegorical nature of which eluded them completely.

For her part, Katharina Kepler didn’t help her own case. Prickly in character and known to brawl, she first tried suing Ursula for slander — a strikingly modern American approach but, in medieval Germany, effective only in stoking the fire, for Ursula’s well-connected family had ties to local authorities. Then she tried bribing the magistrate into dismissing her case by offering him a silver chalice, which was promptly interpreted as an admission of guilt, and the civil case was escalated to a criminal trial for witchcraft.

In the midst of this tumult, Kepler’s infant daughter, named for his mother, died of epilepsy, followed by another son, four years old, of smallpox.

Having taken his mother’s defense upon himself as soon as he first learned of the accusation, the bereaved Kepler devoted six years to the trial, all the while trying to continue his scientific work and to see through the publication of the major astronomical catalog he had been composing since he inherited Tycho’s data. Working remotely from Linz, Kepler first wrote various petitions on Katharina’s behalf, then mounted a meticulous legal defense in writing. He requested trial documentation of witness testimonies and transcripts of his mother’s interrogations. He then journeyed across the country once more, sitting with Katharina in prison and talking with her for hours on end to assemble information about the people and events of the small town he had left long ago. Despite the allegation that she was demented, the seventy-something Katharina’s memory was astonishing — she recalled in granular detail incidents that had taken place years earlier.

Kepler set out to disprove each of the forty-nine “points of disgrace” hurled against his mother, using the scientific method to uncover the natural causes behind the supernatural evils she had allegedly wrought on the townspeople. He confirmed that Ursula had had an abortion, that the teenaged girl had numbed her arm by carrying too many bricks, that the schoolmaster had lamed his leg by tripping into a ditch, that the butcher suffered from lumbago.

None of Kepler’s epistolary efforts at reason worked. Five years into the ordeal, an order for Katharina’s arrest was served. In the small hours of an August night, armed guards barged into her daughter’s house and found Katharina, who had heard the disturbance, hiding in a wooden linen chest — naked, as she often slept during the hot spells of summer. By one account, she was permitted to clothe herself before being taken away; by another, she was carried out disrobed inside the trunk to avoid a public disturbance and hauled to prison for another interrogation. So gratuitous was the fabrication of evidence that even Katharina’s composure through the indignities was held against her — the fact that she didn’t cry during the proceedings was cited as proof of unrepentant liaison with the Devil. Kepler had to explain to the court that he had never seen his stoic mother shed a single tear — not when his father left in Johannes’s childhood, not during the long years Katharina spent raising her children alone, not in the many losses of old age.

Katharina was threatened with being stretched on a wheel — a diabolical device commonly used to extract confessions — unless she admitted to sorcery. This elderly woman, who had outlived her era’s life expectancy by decades, would spend the next fourteen months imprisoned in a dark room, sitting and sleeping on the stone floor to which she was shackled with a heavy iron chain. She faced the threats with self-possession and confessed nothing.

The breaking wheel

In a last recourse, Kepler uprooted his entire family, left his teaching position, and traveled again to his hometown as the Thirty Years’ War raged on. I wonder if he wondered during that dispiriting journey why he had written The Dream in the first place, wondered whether the price of any truth is to be capped at so great a personal cost.

Long ago, as a student at Tübingen, Kepler had read Plutarch’s The Face on the Moon — the mythical story of a traveler who sails to a group of islands north of Britain inhabited by people who know secret passages to the Moon. There is no science in Plutarch’s story — it is pure fantasy. And yet it employs the same simple, clever device that Kepler himself would use in The Dream fifteen centuries later to unsettle the reader’s anthropocentric bias: In considering the Moon as a potential habitat for life, Plutarch pointed out that the idea of life in saltwater seems unfathomable to air-breathing creatures such as ourselves, and yet life in the oceans exists. It would be another eighteen centuries before we would fully awaken not only to the fact of marine life but to the complexity and splendor of this barely fathomable reality when Rachel Carson pioneered a new aesthetic of poetic science writing, inviting the human reader to consider Earth from the nonhuman perspective of sea creatures.

Kepler first read Plutarch’s story in 1595, but it wasn’t until the solar eclipse of 1605, the observations of which first gave him the insight that the orbits of the planets were ellipses rather than circles, that he began seriously considering the allegory as a means of illustrating Copernican ideas. Where Plutarch had explored space travel as metaphysics, Kepler made it a sandbox for real physics, exploring gravity and planetary motion. In writing about the takeoff of his imaginary spaceship, for instance, he makes clear that he has a theoretical model of gravity factoring in the demands that breaking away from Earth’s gravitational grip would place on cosmic voyagers. He goes on to add that while leaving Earth’s gravitational pull would be toilsome, once the spaceship is in the gravity-free “aether,” hardly any force would be needed to keep it in motion — an early understanding of inertia in the modern sense, predating by decades Newton’s first law of motion, which states that a body will move at a steady velocity unless acted upon by an outside force.

In a passage at once insightful and amusing, Kepler describes the physical requirements for his lunar travelers — a prescient description of astronaut training:

No inactive persons are accepted…no fat ones; no pleasure-loving ones; we choose only those who have spent their lives on horseback, or have shipped often to the Indies and are accustomed to subsisting on hardtack, garlic, dried fish and unpalatable fare.

Three centuries later, the early polar explorer Ernest Shackleton would post a similar recruitment ad for his pioneering Antarctic expedition:

Men wanted for hazardous journey, small wages, bitter cold, long months of complete darkness, constant danger, safe return doubtful, honor and recognition in case of success.

When a woman named Peggy Peregrine expressed interest on behalf of an eager female trio, Shackleton dryly replied: “There are no vacancies for the opposite sex on the expedition.” Half a century later, the Russian cosmonaut Valentina Tereshkova would become the first woman to exit Earth’s atmosphere on a spacecraft guided by Kepler’s laws.

After years of exerting reason against superstition, Kepler ultimately succeeded in getting his mother acquitted. But the seventy-five-year-old woman never recovered from the trauma of the trial and the bitter German winter spent in the unheated prison. On April 13, 1622, shortly after she was released, Katharina Kepler died, adding to her son’s litany of losses. A quarter millennium later, Emily Dickinson would write in a poem the central metaphor of which draws on Kepler’s legacy:

Each that we lose takes part of us;
A crescent still abides,
Which like the moon, some turbid night,
Is summoned by the tides.

A few months after his mother’s death, Kepler received a letter from Christoph Besold — the classmate who had stuck up for his lunar dissertation thirty years earlier, now a successful attorney and professor of law. Having witnessed Katharina’s harrowing fate, Besold had worked to expose the ignorance and abuses of power that sealed it, procuring a decree from the duke of Kepler’s home duchy prohibiting any other witchcraft trials unsanctioned by the Supreme Court in the urban and presumably far less superstitious Stuttgart. “While neither your name nor that of your mother is mentioned in the edict,” Besold wrote to his old friend, “everyone knows that it is at the bottom of it. You have rendered an inestimable service to the whole world, and someday your name will be blessed for it.”

Kepler was unconsoled by the decree — perhaps he knew that policy change and cultural change are hardly the same thing, existing on different time scales. He spent the remaining years of his life obsessively annotating The Dream with two hundred twenty-three footnotes — a volume of hypertext equal to the story itself — intended to dispel superstitious interpretations by delineating his exact scientific reasons for using the symbols and metaphors he did.

In his ninety-sixth footnote, Kepler plainly stated “the hypothesis of the whole dream”: “an argument for the motion of the Earth, or rather a refutation of arguments constructed, on the basis of perception, against the motion of the Earth.” Fifty footnotes later, he reiterated the point by asserting that he envisioned the allegory as “a pleasant retort” to Ptolemaic parochialism. In a trailblazing systematic effort to unmoor scientific truth from the illusions of commonsense perception, he wrote:

Everyone says it is plain that the stars go around the earth while the Earth remains still. I say that it is plain to the eyes of the lunar people that our Earth, which is their Volva, goes around while their moon is still. If it be said that the lunatic perceptions of my moon-dwellers are deceived, I retort with equal justice that the terrestrial senses of the Earth-dwellers are devoid of reason.

Copernicus’s heliocentric universe, 1543.

In another footnote, Kepler defined gravity as “a power similar to magnetic power — a mutual attraction,” and described its chief law:

The attractive power is greater in the case of two bodies that are near to each other than it is in the case of bodies that are far apart. Therefore, bodies more strongly resist separation one from the other when they are still close together.

A further footnote pointed out that gravity is a universal force affecting bodies beyond the Earth, and that lunar gravity is responsible for earthly tides: “The clearest evidence of the relationship between earth and the moon is the ebb and flow of the seas.” This fact, which became central to Newton’s laws and which is now so commonplace that schoolchildren point to it as plain evidence of gravity, was far from accepted in Kepler’s scientific community. Galileo, who was right about so much, was also wrong about so much — something worth remembering as we train ourselves in the cultural acrobatics of nuanced appreciation without idolatry. Galileo believed, for instance, that comets were vapors of the earth — a notion Tycho Brahe disproved by demonstrating that comets are celestial objects moving through space along computable trajectories after observing the very comet that had made six-year-old Kepler fall in love with astronomy. Galileo didn’t merely deny that tides were caused by the Moon — he went as far as to mock Kepler’s assertion that they do. “That concept is completely repugnant to my mind,” he wrote — not even in a private letter but in his landmark Dialogue on the Two Chief World Systems — scoffing that “though [Kepler] has at his fingertips the motions attributed to the Earth, he has nevertheless lent his ear and his assent to the Moon’s dominion over the waters, to occult properties, and to such puerilities.”

Kepler took particular care with the portion of the allegory he saw as most directly responsible for his mother’s witchcraft trial — the appearance of nine spirits, summoned by the protagonist’s mother. In a footnote, he explained that these symbolize the nine Greek muses. In one of the story’s more cryptic sentences, Kepler wrote of these spirits: “One, particularly friendly to me, most gentle and purest of all, is called forth by twenty-one characters.” In his subsequent defense in footnotes, he explained that the phrase “twenty-one characters” refers to the number of letters used to spell Astronomia Copernicana. The friendliest spirit represents Urania — the ancient Greek muse of astronomy, which Kepler considered the most reliable of the sciences:

Although all the sciences are gentle and harmless in themselves (and on that account they are not those wicked and good-for-nothing spirits with whom witches and fortune-tellers have dealings…), this is especially true of astronomy because of the very nature of its subject matter.

Urania, the ancient Greek muse of astronomy, as depicted in an 1885 Italian book of popular astronomy. (Available as a print.)

When the astronomer William Herschel discovered the seventh planet from the sun a century and a half later, he named it Uranus, after the same muse. Elsewhere in Germany, a young Beethoven heard of the discovery and wondered in the marginalia of one of his compositions: “What will they think of my music on the star of Urania?” Another two centuries later, when Ann Druyan and Carl Sagan compose the Golden Record as a portrait of humanity in sound and image, Beethoven’s Fifth Symphony sails into the cosmos aboard the Voyager spacecraft alongside a piece by the composer Laurie Spiegel based on Kepler’s Harmony of the World.

Kepler was unambiguous about the broader political intent of his allegory. The year after his mother’s death, he wrote to an astronomer friend:

Would it be a great crime to paint the cyclopian morals of this period in livid colors, but for the sake of caution, to depart from the earth with such writing and secede to the moon?

Isn’t it better, he wonders in another stroke of psychological genius, to illustrate the monstrosity of people’s ignorance by way of the ignorance of imaginary others? He hoped that by seeing the absurdity of the lunar people’s belief that the Moon is the center of the universe, the inhabitants of Earth would have the insight and integrity to question their own conviction of centrality. Three hundred fifty years later, when fifteen prominent poets are asked to contribute a “statement on poetics” for an influential anthology, Denise Levertov — the only woman of the fifteen — would state that poetry’s highest task is “to awaken sleepers by other means than shock.” This must have been what Kepler aimed to do with The Dream — his serenade to the poetics of science, aimed at awakening.

In the wake of his mother’s witchcraft trial, Kepler made another observation centuries ahead of its time, even ahead of the seventeenth-century French philosopher François Poullain de la Barre’s landmark assertion that “the mind has no sex.” In Kepler’s time, long before the discovery of genetics, it was believed that children bore a resemblance to their mothers, in physiognomy and character, because they were born under the same constellation. But Kepler was keenly aware of how different he and Katharina were as people, how divergent their worldviews and their fates — he, a meek leading scientist about to turn the world over; she, a mercurial, illiterate woman on trial for witchcraft. If the horoscopes he had once drawn for a living did not determine a person’s life-path, Kepler couldn’t help but wonder what did — here was a scientist in search of causality. A quarter millennium before social psychology existed as a formal field of study, he reasoned that what had gotten his mother into all this trouble in the first place — her ignorant beliefs and behaviors taken for the work of evil spirits, her social marginalization as a widow — was the fact that she had never benefited from the education her son, as a man, had received. In the fourth section of The Harmony of the World — his most daring and speculative foray into natural philosophy — Kepler writes in a chapter devoted to “metaphysical, psychological, and astrological” matters:

I know a woman who was born under almost the same aspects, with a temperament which was certainly very restless, but by which she not only has no advantage in book learning (that is not surprising in a woman) but also disturbs the whole of her town, and is the author of her own lamentable misfortune.

In the very next sentence, Kepler identifies the woman in question as his own mother and proceeds to note that she never received the privileges he did. “I was born a man, not a woman,” he writes, “a difference in sex which the astrologers seek in vain in the heavens.” The difference between the fate of the sexes, Kepler suggests, is not in the heavens but in the earthly construction of gender as a function of culture. It was not his mother’s nature that made her ignorant, but the consequences of her social standing in a world that rendered its opportunities for intellectual illumination and self-actualization as fixed as the stars.
