The Island of Knowledge: How to Live with Mystery in a Culture Obsessed with Certainty and Definitive Answers


“We strive toward knowledge, always more knowledge, but must understand that we are, and will remain, surrounded by mystery.”

“Our human definition of ‘everything’ gives us, at best, a tiny penlight to help us with our wanderings,” Benjamen Walker offered in an episode of his excellent Theory of Everything podcast as we shared a conversation about illumination and the art of discovery. Thirty years earlier, Carl Sagan had captured this idea in his masterwork Varieties of Scientific Experience, where he asserted: “If we ever reach the point where we think we thoroughly understand who we are and where we came from, we will have failed.” This must be what Rilke, too, had at heart when he exhorted us to live the questions. And yet if there is one common denominator across the entire history of human culture, it is the insatiable hunger to know the unknowable — that is, to know everything, and to know it with certainty, which is itself the enemy of the human spirit.

The perplexities and paradoxes of that quintessential human longing, and how the progress of modern science has compounded it, is what astrophysicist and philosopher Marcelo Gleiser examines in The Island of Knowledge: The Limits of Science and the Search for Meaning (public library).

Partway between Hannah Arendt’s timeless manifesto for the unanswerable questions at the heart of meaning and Stuart Firestein’s case for how not-knowing drives science, Gleiser explores our commitment to knowledge and our parallel flirtation with the mystery of the unknown.

What emerges is at once a celebration of human achievement and a gentle reminder that the appropriate reaction to scientific and technological progress is not arrogance over the knowledge conquered, which seems to be our civilizational modus operandi, but humility in the face of what remains to be known and, perhaps above all, what may always remain unknowable.

Gleiser begins by posing the question of whether there are fundamental limits to how much of the universe and our place in it science can explain, with a concrete focus on physical reality. Echoing cognitive scientist Alexandra Horowitz’s eye-opening exploration of why our minds miss the vast majority of what is going on around us, he writes:

What we see of the world is only a sliver of what’s “out there.” There is much that is invisible to the eye, even when we augment our sensorial perception with telescopes, microscopes, and other tools of exploration. Like our senses, every instrument has a range. Because much of Nature remains hidden from us, our view of the world is based only on the fraction of reality that we can measure and analyze. Science, as our narrative describing what we see and what we conjecture exists in the natural world, is thus necessarily limited, telling only part of the story… We strive toward knowledge, always more knowledge, but must understand that we are, and will remain, surrounded by mystery… It is the flirting with this mystery, the urge to go beyond the boundaries of the known, that feeds our creative impulse, that makes us want to know more.

In a sentiment that bridges Philip K. Dick’s formulation of reality as “that which, when you stop believing in it, doesn’t go away” with Richard Feynman’s iconic monologue on knowledge and mystery, Gleiser adds:

The map of what we call reality is an ever-shifting mosaic of ideas.


The incompleteness of knowledge and the limits of our scientific worldview only add to the richness of our search for meaning, as they align science with our human fallibility and aspirations.

Gleiser notes that while modern science has made tremendous strides in illuminating the neuronal infrastructure of the brain, it has in the process reduced the mind to mere chemical operations, not only failing to advance but perhaps even impoverishing our understanding and sense of being. He admonishes against mistaking measurement for meaning:

There is no such thing as an exact measurement. Every measurement must be stated within its precision and quoted together with “error bars” estimating the magnitude of errors. High-precision measurements are simply measurements with small error bars or high confidence levels; there are no perfect, zero-error measurements.


Technology limits how deeply experiments can probe into physical reality. That is to say, machines determine what we can measure and thus what scientists can learn about the Universe and ourselves. Being human inventions, machines depend on our creativity and available resources. When successful, they measure with ever-higher accuracy and on occasion may also reveal the unexpected.


But the essence of empirical science is that Nature always has the last word… It then follows that if we only have limited access to Nature through our tools and, more subtly, through our restricted methods of investigation, our knowledge of the natural world is necessarily limited.

And yet even though much of the world remains invisible to us at any given moment, Gleiser argues that this is what the human imagination thrives on. At the same time, however, the very instruments that we create with this restless imagination begin to shape what is perceivable, and thus what is known, marking “reality” a Rube Goldberg machine of detectable measurements. Gleiser writes:

If large portions of the world remain unseen or inaccessible to us, we must consider the meaning of the word “reality” with great care. We must consider whether there is such a thing as an “ultimate reality” out there — the final substrate of all there is — and, if so, whether we can ever hope to grasp it in its totality.


Our perception of what is real evolves with the instruments we use to probe Nature. Gradually, some of what was unknown becomes known. For this reason, what we call “reality” is always changing… The version of reality we might call “true” at one time will not remain true at another.


As long as technology advances — and there is no reason to suppose that it will ever stop advancing for as long as we are around — we cannot foresee an end to this quest. The ultimate truth is elusive, a phantom.

To illustrate this notion, Gleiser constructs the metaphor after which his book is titled — he paints knowledge as an island surrounded by the vast ocean of the unknown; as we learn more, the island expands into the ocean, its coastline marking the ever-shifting boundary between the known and the unknown. Paraphrasing the Socratic paradox, Gleiser writes:

Learning more about the world doesn’t lead to a point closer to a final destination — whose existence is nothing but a hopeful assumption anyway — but to more questions and mysteries. The more we know, the more exposed we are to our ignorance, and the more we know to ask.

Echoing Ray Bradbury’s poetic conviction that it’s part of human nature “to start with romance and build to a reality,” Gleiser adds:

This realization should open doors, not close them, since it makes the search for knowledge an open-ended pursuit, an endless romance with the unknown.

Gleiser admonishes against the limiting notion that we only have two options — staunch scientism, with its blind faith in science’s ability to permanently solve the mysteries of the unknown, and religious obscurantism, with its superstitious avoidance of inconvenient facts. Instead, he offers a third approach “based on how an understanding of the way we probe reality can be a source of endless inspiration without the need for setting final goals or promises of eternal truths.” In an assertion that invokes Sagan’s famous case for the vital balance between skepticism and openness, Gleiser writes:

This unsettled existence is the very blood of science. Science needs to fail to move forward. Theories need to break down; their limits need to be exposed. As tools probe deeper into Nature, they expose the cracks of old theories and allow new ones to emerge. However, we should not be fooled into believing that this process has an end.

I recently tussled with another facet of this issue — the umwelt of the unanswerable — in contemplating the future of machines that think for John Brockman’s annual Edge question. But what makes Gleiser’s point particularly gladdening is the underlying implication that despite its pursuit of answers, science thrives on uncertainty and thus necessitates an element of unflinching faith — faith in the process of the pursuit rather than the outcome, but faith nonetheless. And while the difference between science and religion might be, as Krista Tippett elegantly offered, in the questions they ask rather than the answers they offer, Gleiser suggests that both the fault line and the common ground between the two is a matter of how each relates to mystery:

Can we make sense of the world without belief? This is a central question behind the science and faith dichotomy… Religious myths attempt to explain the unknown with the unknowable while science attempts to explain the unknown with the knowable.


Both the scientist and the faithful believe in unexplained causation, that is, in things happening for unknown reasons, even if the nature of the cause is completely different for each. In the sciences, this belief is most obvious when there is an attempt to extrapolate a theory or model beyond its tested limits, as in “gravity works the same way across the entire Universe,” or “the theory of evolution by natural selection applies to all forms of life, including extraterrestrial ones.” These extrapolations are crucial to advance knowledge into unexplored territory. The scientist feels justified in doing so, given the accumulated power of her theories to explain so much of the world. We can even say, with slight impropriety, that her faith is empirically validated.

Citing Newton and Einstein as prime examples of scientists who used wholly intuitive faith to advance their empirical and theoretical breakthroughs — one by extrapolating from his gravitational findings to assert that the universe is infinite and the other by inventing the notion of a “universal constant” to discuss the finitude of space — Gleiser adds:

To go beyond the known, both Newton and Einstein had to take intellectual risks, making assumptions based on intuition and personal prejudice. That they did so, knowing that their speculative theories were necessarily faulty and limited, illustrates the power of belief in the creative process of two of the greatest scientists of all time. To a greater or lesser extent, every person engaged in the advancement of knowledge does the same.

The Island of Knowledge is an illuminating read in its totality — Gleiser goes on to explore how conceptual leaps and bounds have shaped our search for meaning, what quantum mechanics reveal about the nature of physical reality, and how the evolution of machines and mathematics might affect our ideas about the limits of knowledge.

For a fine complement, see Hannah Arendt on thinking vs. knowing and the crucial difference between truth and meaning and astrophysicist Janna Levin on whether the universe is infinite or finite, then treat yourself to Gleiser’s magnificent conversation with novelist Marilynne Robinson — herself a thinker of perceptive and nuanced insight on mystery — on the existentially indispensable On Being:

GLEISER: To think of science as separate from spirituality to me is a big mistake… There is nothing that says that science should be dispassionate about the spirit or the life of the spirit. And to me it’s quite the opposite. It’s exactly because I feel very spiritually connected with nature that I am a scientist. And to write equations on a blackboard and to come up with models about how nature works is, in a sense, a form of worship of that spirituality.


ROBINSON: One of the things that is fascinating is that we don’t know who we are. Human beings in acting out history describe themselves and every new epic is a new description of what human beings are. Every life is a new description of what human beings are. Every work of science, every object of art is new information. And it is inconceivable at this point that we could say anything final about what the human mind is, because it is demonstrating … in beautiful ways and terrifying ways, that it will surprise us over and over and over again.

The Absurdity of Infinity: Astrophysicist Janna Levin Explains Whether the Universe Is Infinite or Finite in Letters to Her Mother


“The simpler the insight, the more profound the conclusion.”

In 1998, while on the cusp of becoming one of the most significant theoretical cosmologists of our time, mathematician-turned-astrophysicist Janna Levin left her post at Berkeley and moved across the Atlantic for a prestigious position at Cambridge University. During the year and a half there, she had the time and space to contemplate the question that would eventually become the epicenter of her career — whether the universe is infinite or finite. What began as a series of letters to her mother, Sandy, eventually became an unusual diary of Levin’s “social exile as a roaming scientist,” and was finally published as How the Universe Got Its Spots: Diary of a Finite Time in a Finite Space (public library) — a most unusual and absorbing account of the paradoxes of finitude.

“I’m writing to you because I know you’re curious but afraid to ask,” Levin offers in the opening letter — a “you” that instantly becomes as much her mother as the person Virginia Woolf memorably termed “the common reader.” From there, she springboards into remarkably intelligent yet inviting explorations of some of the biggest questions that the universe poses — questions most of us contemplate, sometimes consciously but mostly not, just by virtue of being sentient participants in the chaos and enchantment of existence.

A 1617 depiction of the notion of non-space, long before the concept of vacuum existed, found in Michael Benson's book 'Cosmigraphics'—a visual history of understanding the universe. Click image for more.

In an entry from September 3, 1998, Levin fleshes out her ideas on infinity and writes with exquisite Saganesque sensitivity to the poetics of science:

For a long time I believed the universe was infinite. Which is to say, I just never questioned this assumption that the universe was infinite. But if I had given the question more attention, maybe I would have realized sooner. The universe is the three-dimensional space we live in and the time we watch pass on our clocks. It is our north and south, our east and west, our up and down. Our past and future. As far as the eye can see there appears to be no bound to our three spatial dimensions and we have no expectation for an end to time. The universe is inhabited by giant clusters of galaxies, each galaxy a conglomerate of a billion or a trillion stars. The Milky Way, our galaxy, has an unfathomably dense core of millions of stars with beautiful arms, a skeleton of stars, spiraling out from this core. The earth lives out in the sparsely populated arms orbiting the sun, an ordinary star, with our planetary companions. Our humble solar system. Here we are. A small planet, an ordinary star, a huge cosmos. But we’re alive and we’re sentient. Pooling our efforts and passing our secrets from generation to generation, we’ve lifted ourselves off this blue and green water-soaked rock to throw our vision far beyond the limitations of our eyes.

The universe is full of galaxies and their stars. Probably, hopefully, there is other life out there and background light and maybe some ripples in space. There are bright objects and dark objects. Things we can see and things we can’t. Things we know about and things we don’t. All of it. This glut of ingredients could carry on in every direction forever. Never ending. Just when you think you’ve seen the last of them, there’s another galaxy and beyond that one another infinite number of galaxies.

Illustration from Thomas Wright’s visionary 1750 treatise 'An Original Theory,' found in Michael Benson's book 'Cosmigraphics'—a visual history of understanding the universe. Click image for more.

But having painted this bewitching backdrop for our intuitive beliefs, Levin sublimates the poet to the scientist, pointing out that however alluring these intuitions may feel, they are nonetheless ungrounded in empirical fact:

No infinity has ever been observed in nature. Nor is infinity tolerated in a scientific theory — except we keep assuming the universe itself is infinite.

It wouldn’t be so bad if Einstein hadn’t taught us better. And here the ideas collide so I’ll just pour them out unfiltered. Space is not just an abstract notion but a mutable, evolving field. It can begin and end, be born and die. Space is curved, it is a geometry, and our experience of gravity, the pull of the earth and our orbit around the sun, is just a free fall along the curves in space. From this huge insight people realized the universe must be expanding. The space between the galaxies is actually stretching even if the galaxies themselves were otherwise to stay put. The universe is growing, aging. And if it’s expanding today, it must have been smaller once, in the sense that everything was once closer together, so close that everything was on top of each other, essentially in the same place, and before that it must not have been at all. The universe had a beginning. There was once nothing and now there is something. What sways me even more, if an ultimate theory of everything is found, a theory beyond Einstein’s, then gravity and matter and energy are all ultimately different expressions of the same thing. We’re all intrinsically of the same substance. The fabric of the universe is just a coherent weave from the same threads that make our bodies. How much more absurd it becomes to believe that the universe, space and time could possibly be infinite when all of us are finite.

A decade and a half later, Alan Lightman would come to write with a similar scientific poeticism about why we long for permanence in a universe defined by constant change. But however poetic the premise, Levin brings a mathematician’s precision to her “reasons for believing the universe is finite, unpopular as they are in some scientific crowds.” In another entry twelve days later, she writes:

Infinity is a demented concept…

Infinity is a limit and is not a proper number. No matter how big a number you think of, I can add 1 to it and make it that much bigger. The number of numbers is infinite. I could never recite the infinite numbers, since I only have a finite lifetime. But I can imagine it as a hypothetical possibility, as the inevitable limit of a never-ending sequence. The limit goes the other way, too, since I can consider the infinitely small, the infinitesimal. No matter how small you try to divide the number 1, I can divide it smaller still. While I could again imagine doing this forever, I can never do this in practice. But I can understand infinity abstractly and so accept it for what it is.

Pointing out that all titans of science — including Galileo, Aristotle, and Cantor — were besotted with the notion of infinity at some point, “each visiting the idea for a time and then abandoning the pursuit,” Levin notes that we can neither accept nor dismiss infinity on the basis of popular opinion alone. In early October, she writes:

Where in the hierarchy of infinity would an infinite universe lie? An infinite universe can host an infinite amount of stuff and an infinite number of events. An infinite number of planets. An infinite number of people on those planets. Surely there must be another planet so very nearly like the earth as to be indistinguishable, in fact an infinite number of them, each with a variety of inhabitants, an infinite number of which must be infinitely close to this set of inhabitants. Another you, another me. Or there’d be another you out there with a slightly different life and a different set of siblings, parents, offspring. This is hard to believe. Is it arrogance or logic that makes me believe this is wrong? There’s just one me, one you. The universe cannot be infinite.


I welcome the infinite in mathematics, where … it is not absurd nor demented. But I’d be pretty shaken to find the infinite in nature. I don’t feel robbed living my days in the physical with its tender admission of the finite. I still get to live with the infinite possibilities of mathematics, if only in my head.

Illustration by Lisbeth Zwerger for 'Alice in Wonderland.' Click image for more.

Understanding the infinite — both as a mathematical possibility and an impossibility of the physical universe — might be more a matter of coming to terms with infinite simplicity than with infinite complexity. In an entry from early February of 1999, Levin echoes Margaret Mead’s famous proclamation about clarity and writes:

I try to find a simple expression for my ideas. I figure if there is none, the ideas must be wrong. When I first started to work on topology I wondered about complex properties of spaces and didn’t take my own suggestions seriously until I realized the simple way to ask the question: is the universe infinite? Einstein’s simplest insights were profound. The simpler the insight, the more profound the conclusion.

In the remainder of How the Universe Got Its Spots, which is unbearably beautiful in both intellectual elegance and stylistic splendor, Levin goes on to explore questions of quantum relativity and freewill, death and black holes, spacetime and Wonderland, and more. Complement it with Levin on science, free will, and the human spirit, then revisit Alan Lightman on how dark energy explains why we exist and treat yourself to this poetic primer on the universe written in the 1,000 most common words in the English language.

The Paradox of Intellectual Promiscuity: Stephen Jay Gould on What Nabokov’s Butterfly Studies Reveal About the Unity of Creativity


“There is no science without fancy, and no art without facts.”

The history of human culture is rife with creators hailed as geniuses in one domain who also had a notable but lesser-known talent in another — take, for instance, Richard Feynman’s sketches, J.R.R. Tolkien’s illustrations, Sylvia Plath’s drawings, William Faulkner’s Jazz Age illustrations, Flannery O’Connor’s cartoons, David Lynch’s conceptual art, and Zelda Fitzgerald’s watercolors. Only rarely, however, do we encounter a person who has contributed to culture in a significant way in both art and science.

No one, argues Stephen Jay Gould — perhaps the greatest science-storyteller humanity has ever had, a man of uncommon genius in the art of dot-connecting — better merits recognition for such duality of genius than Vladimir Nabokov, a titan of literary storytelling and a formidable lepidopterist who studied, classified, and drew a major group of butterflies, and even served as unofficial curator of lepidoptery at Harvard’s Museum of Comparative Zoology.

In a spectacular essay titled “The Paradox of Intellectual Promiscuity,” found in his altogether indispensable final essay collection I Have Landed: The End of a Beginning in Natural History (public library), Gould uses Nabokov’s case to make a beautiful and urgently necessary broader case against our culture’s chronic tendency to pit art and science against one another — “We have been befogged by a set of stereotypes about conflict and difference between these two great domains of human understanding,” he laments — and to assume that if a person has talent and passion for both areas, he or she can achieve greatness in only one and is necessarily a mere hobbyist in the other.

Gould writes:

We tend toward benign toleration when great thinkers and artists pursue disparate activities as a harmless hobby, robbing little time from their fundamental achievements… We grieve when we sense that a subsidiary interest stole precious items from a primary enterprise of great value… When we recognize that a secondary passion took substantial time from a primary source of fame, we try to assuage our grief over lost novels, symphonies, or discoveries by convincing ourselves that a hero’s subsidiary love must have informed or enriched his primary activity — in other words, that the loss in quantity might be recompensed by a gain in quality.

Nabokov's drawing of 'Eugenia onegini,' named for Aleksandr Pushkin's novel in verse, Eugene Onegin, which Nabokov translated. The illustration appeared on the endpaper of 'Conclusive Evidence,' Nabokov's autobiography.

But Gould argues that neither lamentation of such “intellectual promiscuity” detracting from the primary endeavor nor the manufactured comfort of believing that one domain enriched the other is an appropriate response to Nabokov’s two great loves, literature and butterflies. Gould unambiguously annihilates a common misconception about the great author:

Nabokov was no amateur (in the pejorative sense of the term), but a fully qualified, clearly talented, duly employed professional taxonomist, with recognized “world class” expertise in the biology and classification of a major group, the Latin American Polyommatini, popularly known to butterfly aficionados as “blues.”

No passion burned longer, or more deeply, in Nabokov’s life than his love for the natural history and taxonomy of butterflies. He began in early childhood, encouraged by a traditional interest in natural history among the upper-class intelligentsia of Russia (not to mention the attendant economic advantages of time, resources, and opportunity).


The reasons often given for attributing to Nabokov either an amateur, or even only a dilettante’s, status arise from simple ignorance of accepted definitions for professionalism in this field.


Nabokov loved his butterflies as much as his literature. He worked for years as a fully professional taxonomist, publishing more than a dozen papers that have stood the test of substantial time.

That he received an annual salary of merely a thousand dollars during his six years at Harvard’s zoology museum and worked under the vague title Research Fellow shouldn’t be used as evidence of Nabokov’s amateurishness — in making a larger point about the rich history of people working on what they love for little or no pay, Gould points out that several esteemed curators at the museum during his own tenure worked as volunteers for the symbolic annual salary of one dollar. In one of his many spectacular, almost outraged asides — Gould’s signature intelligent zingers — he drives home the point that there is little correlation between merit and prestige:

Every field includes some clunkers and nitwits, even in high positions!

Returning to the two camps of explaining Nabokov’s dual giftedness — and parallel talents in general — Gould writes:

In seeking some explanation for legitimate grief, we may find solace in claiming that Nabokov’s transcendent genius permitted him to make as uniquely innovative and distinctive a contribution to lepidoptery as to literature. However much we may wish that he had chosen a different distribution for his time, we can at least, with appropriate generosity, grant his equal impact and benefit upon natural history… However, no natural historian has ever viewed Nabokov as an innovator, or as an inhabitant of what humanists call the “vanguard” (not to mention the avant-garde) and scientists the “cutting edge.” Nabokov may have been a major general of literature, but he can only be ranked as a trustworthy, highly trained career infantryman in natural history.

Even Nabokov’s butterfly drawings, Gould points out, were great but far from masterworks of natural history illustration, especially in comparison to the work of such visionaries as butterfly-drawing grand dame Maria Merian.

Here, we are reminded of another perilous pathology of our culture — in the cult of genius, as in any cult, we leave no room for nuance; mere greatness is not good enough — one must lay a claim on grandeur. This is perhaps the most extreme testament to how perfectionism thwarts creativity.

But despite his mere greatness at lepidoptery, Nabokov regarded his time at the zoology museum as the most “delightful and thrilling” in his adult life — so creatively electrified was the author there that his years at Harvard even produced history’s most epic and entertaining account of food poisoning. But his love of butterflies began much earlier. In fact, one of the very first things Nabokov wrote in English, at the age of twelve, was a paper on Lepidoptera. The only reason it wasn’t published was that it turned out the butterfly in question had already been described by someone else.

This remark, which Gould makes rather in passing, made me wonder whether the incident instilled in young Vladimir an early reverence for attribution of discovery. As Gould later notes in another passing mention, Nabokov frequently voiced annoyance with scientists and science-writers not attributing discovery — not acknowledging the person who discovered and named a butterfly species. Therein lies a broader, and rather timely, lament about our culture’s failure to honor discovery as a creative act and a subset of scholarship — such a scientist, after all, doesn’t invent a species, for it already exists in nature, but discovers it, names it, and contextualizes it in the canon of natural history. It is no coincidence that Nabokov’s own role at the Harvard Museum of Comparative Zoology was that of curator, for this is the task of the curator — to describe, arrange, and contextualize what already exists in such a way as to shed new light on its meaning, to discover and un-cover its significance and place in the canon of ideas.

Embedded in this act is also a lineage of discovery, similar to the “links in a chain” metaphor Pete Seeger used for creativity: I learned of Nabokov’s pet peeve about discovery thanks to Stephen Jay Gould — perhaps the greatest curator of scientific ideas the world has ever known, the greatest contextualizer of such ideas in the popular imagination — and you learned of it via me, and the person you tell about this will learn of it via you. All of us are links in the evolutionary chain of ideas, much like each butterfly species discovered is a link in the evolutionary chain of natural history. This is why Richard Dawkins, in coining the word meme, used a metaphor from evolutionary biology to describe how ideas spread: “Just as genes propagate themselves in the gene pool by leaping from body to body via sperms or eggs, so memes propagate themselves in the meme pool by leaping from brain to brain.”

But back to Nabokov: His dedication to the integrity of discovery prompted him to write a short poem titled “A Discovery” in 1943:

Dark pictures, thrones, the stones that pilgrims kiss
Poems that take a thousand years to die
But ape the immortality of this
Red label on a little butterfly.

It might also be why he was so passionate about the integrity of detail. In a motto that calls to mind Susan Sontag’s memorable assertion that “a writer is a professional observer,” Nabokov instructed his literature students:

Caress the details, the divine details. In high art and pure science, detail is everything.

Butterfly drawing by Nabokov, August 1958 (Courtesy of Nabokov Museum)

In this, Gould finds the reconciliatory unity between Nabokov’s two great loves and how they communed with one another:

Although time spent on lepidoptery almost surely decreased his literary output, the specific knowledge and the philosophical view of life that Nabokov gained from his scientific career directly forged (or at least strongly contributed to) his unique literary style and excellence… Perhaps the major linkage of science and literature lies in some distinctive, underlying approach that Nabokov applied equally to both domains — a procedure that conferred the same special features upon all his efforts.


Among great twentieth-century thinkers, I know no better case than Nabokov’s for testing the hypothesis that an underlying unity of mental style (at a level clearly meriting the accolade of genius) can explain one man’s success in extensive and fully professional work in two disciplines conventionally viewed as maximally different, if not truly opposed. If we can validate this model for attributing interdisciplinary success to a coordinating and underlying mental uniqueness, rather than invoking the conventional argument about overt influence of one field upon another, then Nabokov’s story may teach us something important about the unity of creativity, and the falsity (or at least the contingency) of our traditional separation, usually in mutual recrimination, of art from science.

Therein, Gould argues, lies the only true solace in the accusation of “intellectual promiscuity.” Debunking the two false explanations of the Nabokov paradox — that “lepidoptery represented a harmless private passion, robbing no substantial time from his literary output” and that “his general genius at least made his lepidoptery as distinctive and as worthy as his literature” — Gould writes:

Nabokov’s two apparently disparate careers therefore find their common ground on the most distinctive feature of his unusual intellect and uncanny skill — the almost obsessive attention to meticulous and accurate detail that served both his literary productions and his taxonomic descriptions so well, and that defined his uncompromising commitment to factuality as both a principle of morality and a guarantor and primary guide to aesthetic quality.

Science and literature therefore gain their union on the most palpable territory of concrete things, and on the value we attribute to accuracy, even in smallest details, as a guide and an anchor for our lives, our loves, and our senses of worth… Of all scientific subfields, none raises the importance of intricate detail to such a plateau of importance as Nabokov’s chosen profession of taxonomic description for small and complex organisms. To function as a competent professional in the systematics of Lepidoptera, Nabokov really had no choice but to embrace such attention to detail, and to develop such respect for nature’s endless variety.


The universal and defining excellence of a professional taxonomist built a substrate for the uncommon, and (in Nabokov’s case) transcendent, excellence of a writer.

But Gould’s most important point of all has little to do with Nabokov and everything to do with the toxic mythologies of creativity to which we, as a culture and as individuals, subscribe:

An ancient, and basically anti-intellectual, current in the creative arts has now begun to flow more strongly than ever before in recent memory-the tempting Siren song of a claim that the spirit of human creativity stands in direct opposition to the rigor in education and observation that breeds both our love for factual detail and our gain of sufficient knowledge and understanding to utilize this record of human achievement and natural wonder.

No more harmful nonsense exists than this common supposition that deepest insight into great questions about the meaning of life or the structure of reality emerges most readily when a free, undisciplined, and uncluttered (read, rather, ignorant and uneducated) mind soars above mere earthly knowledge and concern. The primary reason for emphasizing the supreme aesthetic and moral value of detailed factual accuracy, as Nabokov understood so well, lies in our need to combat this alluring brand of philistinism if we wish to maintain artistic excellence as both a craft and an inspiration.


If we assign too much of our total allotment to the mastery of detail, we will have nothing left for general theory and integrative wonder. But such a silly model of mental functioning can only arise from a false metaphorical comparison of human creativity with irrelevant systems based on fixed and filled containers — pennies in a piggy bank or cookies in a jar.

Gould ends by exhorting us:

Let us celebrate Nabokov’s excellence in natural history, and let us also rejoice that he could use the same mental skills and inclinations to follow another form of bliss.


Human creativity seems to work much as a coordinated and complex piece, whatever the different emphases demanded by disparate subjects-and we will miss the underlying commonality if we only stress the distinctions of external subjects and ignore the unities of internal procedure. If we do not recognize the common concerns and characteristics of all creative human activity, we will fail to grasp several important aspects of intellectual excellence-including the necessary interplay of imagination and observation (theory and empirics) as an intellectual theme, and the confluence of beauty and factuality as a psychological theme-because one field or the other traditionally downplays one side of a requisite duality.


I cannot imagine a better test case for extracting the universals of human creativity than the study of deep similarities in intellectual procedure between the arts and sciences.

No one grasped the extent of this underlying unity better than Vladimir Nabokov, who worked with different excellences as a complete professional in both domains.


Nabokov broke the boundaries of art and science by stating that the most precious desideratum of each domain must also characterize any excellence in the other — for, after all, truth is beauty, and beauty truth.

Gould seals this beautiful truth with a line — an exquisite, ennobling, oft-cited line — from one of Nabokov’s interviews:

There is no science without fancy, and no art without facts.

I Have Landed remains one of the finest tapestries of thought ever woven in the history of science storytelling. Complement this particular thread with Nabokov on inspiration, censorship and solidarity, what makes a great writer, what makes a great reader, and his sublime love letters to his wife.
