I just finished Andrea Wulf’s The Invention of Nature, and I find myself unable to stop thinking about Alexander von Humboldt—not as a historical figure, but as a provocation. A challenge to how I’ve structured my own intellectual life.
The Breadth of a Mind
Throughout my career, I’ve operated under a singular assumption: that real purpose, real contribution, comes from going deep. That’s why I pursued a PhD—to master one domain, to become expert enough in a single field that I might add something meaningful to it. This is how we’re trained to think. Specialization as virtue. Depth as rigor.
But Humboldt’s mind didn’t work that way. His genius was precisely in his refusal to stay within boundaries. Geology, botany, climatology, astronomy, indigenous languages, political philosophy, art—he moved between them not as a dilettante but as someone who understood that the connections between fields were where the most profound insights lived. Nature itself, he saw, was not compartmentalized. Why should knowledge be?
Wulf describes those legendary salons and gatherings where Humboldt would talk for hours, leaping from one subject to another in what must have been an intoxicating torrent of ideas. I found myself frustrated that she never gives us a full transcript, never reconstructs even one of those evenings in complete detail. What did it actually *sound* like when that mind was in motion? How did he weave together observations about Andean geology with thoughts on Goethe’s poetry, with calculations about magnetic fields, with reflections on colonial injustice?
But perhaps that frustration is the point. Perhaps what we’re missing isn’t just the content of those conversations but the entire *mode* of thinking they represented—a mode we’ve systematically discouraged in ourselves.
Reading about Humboldt has given me permission I didn’t know I needed. My career is established. I’m no longer operating from a place of insecurity about what comes next. There are myriad directions I could explore, and for the first time, I don’t see that multiplicity as a threat to focus. Instead, I see it as Humboldt might have: as an opportunity to understand how things connect. What worldview emerges when you’ve achieved relative mastery in more than one domain? What do you see from that vantage point that specialists, by definition, cannot?
This feels like following in the footsteps of one of the greatest minds in history. Not with the hubris of thinking I’ll achieve what he did, but with the humility of recognizing that the pursuit itself—the holistic pursuit—is worthwhile.
The Tragedy of Erasure
And yet, Humboldt’s story is also a cautionary tale about how easily even the most brilliant legacies can be distorted or forgotten.
His disappearance from English-speaking consciousness after World War I wasn’t random. Germany’s role in the wars poisoned the well for German scientists and thinkers, even those who had been cosmopolitan humanists. But there’s something darker here too, something Wulf touches on only glancingly: the grotesque appropriation of naturalist thinking by the Nazis.
Ernst Haeckel, who coined the term “ecology” and was influenced by Humboldt’s holistic approach to nature, also became one of the intellectual architects of racial hierarchy theory. His ideas about biological determinism and racial “purity” were eagerly seized upon by Nazi ideologues. This is the kind of history that makes you queasy to discuss—not because it isn’t true, but because the conversation itself is treacherous. There are people who aren’t ready for it, who will hear any engagement with these ideas as endorsement rather than examination.
But we can’t understand Humboldt’s eclipse without grappling with how his intellectual tradition was weaponized. The same holistic, systems-level thinking that allowed him to see nature as interconnected could be twisted into justifications for social Darwinism and worse. It’s a reminder that ideas, no matter how pure in their original form, don’t exist in a vacuum. They live in history, and history is messy.
Where Are the Borders for Elephants?
One of Humboldt’s great insights was that nature doesn’t respect our categories. Climate zones don’t stop at national borders. Plant species don’t care about human politics. Everything is connected—atmospheric circulation, ocean currents, the distribution of life across the planet.
So when I look at a map of the world now, I can’t help but see it through Humboldtian eyes—and what I see troubles me.
Every border on that map represents a claim by one group of humans over a piece of territory. Sometimes these borders reflect cultural or linguistic differences. More often, they’re arbitrary lines drawn by colonial powers or ancient wars. But even in the best case—even if every border perfectly represented distinct human communities—there’s still a glaring absence.
Where are the borders for gorillas? For elephants? For wolves? Where is their territory represented on our maps?
The answer, of course, is that it isn’t. Or it exists only in the tiny, barely-visible patches we call national parks and reserves. The entire political and economic organization of the planet treats nature not as a stakeholder but as a resource. We’ve excluded the non-human world from our decision-making structures entirely.
This isn’t just morally troubling. It’s also, as Humboldt warned 200 years ago, practically suicidal. We’re part of these systems we’re disrupting. We depend on them. When we treat nature as infinitely exploitable, we’re sawing through the branch we’re sitting on.
The Liberal Dilemma
And yet—and this is where I find myself genuinely stuck—I can’t bring myself to reject the political and economic framework that has, in fact, delivered more human flourishing than any alternative we’ve tried.
When I look at the last 300 years of history, the pattern seems clear: societies that maximize individual freedom, that respect personal liberty, that allow people to pursue their own visions of the good life—these societies have produced not just wealth but innovation, art, scientific progress, and expanding circles of moral concern. Liberal democracy and market economics, for all their flaws, have a track record that command respect.
Every time we’ve tried to subordinate individual freedom to collective planning—whether in the name of the proletariat, the nation, or the five-year plan—the results have ranged from disappointing to catastrophic. There’s something about respecting the autonomy and ingenuity of individual human beings that seems to unlock collective flourishing in ways that centralized control cannot.
But—and this is the Humboldt question—these systems have no mechanism for accounting for nature. The invisible hand of the market can optimize for human preferences, but trees don’t bid in auctions. Rivers don’t vote. The atmosphere doesn’t have property rights.
Wulf is careful in the book to note Humboldt’s warnings about human impact on the environment, but there’s also a tone—especially in the epilogue—that treats human ingenuity itself with suspicion. She uses words like “mischievous” rather than “miraculous” to describe our inventiveness. There’s an implication that our cleverness is inherently destructive, that we’re the bad actors in nature’s story.
I resist this framing. Not because I think we’ve been harmless—we clearly haven’t—but because I don’t want to pathologize human creativity and ambition themselves. The same ingenuity that has created environmental problems has also doubled human life expectancy, reduced absolute poverty, expanded literacy, and yes, even helped us understand the environmental problems we’ve created.
So how do we square this circle? How do we create systems that preserve individual liberty, respect human ingenuity, generate prosperity, AND account for nature as a stakeholder with standing equal to our own?
The Unanswered Questions
Maybe we need another planet. Maybe that’s the answer—expand outward, give ourselves more room, reduce the pressure on Earth by becoming multiplanetary.
But is that good? Is it even possible? And isn’t there something deeply sad about a solution that amounts to: “We’ll just keep doing what we’re doing, but with more real estate”?
Or maybe we’re asking the wrong question. Maybe equilibrium was never the goal. Every species adapts to its environment, changes that environment, and is changed in turn. What we’re experiencing now is just the latest chapter in that story—more rapid than previous changes, certainly, but still fundamentally part of the natural process of evolution and adaptation.
If that’s true, if this is just nature doing what nature does, then maybe we need to stop treating it as a crisis and start treating it as a transition.
But then I think about what we’re losing. The waterfalls Humboldt bathed under. The meadows full of wildflowers and clean air. A world where food doesn’t contain microplastics and oceans aren’t acidifying and you can still hear the sound of genuine silence in the wild.
Even if our current trajectory is “natural” in some technical sense, even if it’s just adaptation and change like any other… I don’t want that world. I don’t want to live in the world we’re creating, and I don’t want to leave it for the generations that follow me.
The Humboldt Legacy
So I’m left with questions more than answers. But perhaps that’s appropriate. Humboldt himself was more explorer than dogmatist, more observer than ideologue. He taught us to see connections, to think in systems, to understand that everything affects everything else.
What strikes me most, returning to where I started, is that Humboldt’s breadth of knowledge wasn’t just about accumulating facts. It was about building a worldview capacious enough to hold complexity. He could move between disciplines because he understood that the divisions between them were artificial, imposed by us for convenience but not reflecting any deeper truth about how reality works.
Maybe that’s what we need now: minds trained not just in depth but in breadth. Not polymaths for the sake of polymathy, but people who can hold multiple frameworks simultaneously, who can think like economists AND ecologists, who understand both the moral power of individual freedom and the physical reality of planetary boundaries.
I don’t know how to reconcile the tensions I’ve described. I don’t know how to build political and economic systems that give nature a seat at the table without sacrificing the individual liberties that have proven so generative. I don’t know if we can have both human flourishing and environmental health, or if we’re headed toward a choice between them.
But I do know that we won’t find answers by staying in our silos. We won’t figure this out through specialization alone. The problems we face are Humboldtian in scale—they cross every boundary we’ve drawn. They demand the kind of holistic, connective thinking that he pioneered.
So maybe the first step is the one Humboldt would take: to learn more broadly, to see more connections, to refuse the tyranny of disciplinary boundaries. Not because it guarantees success, but because the questions we face are bigger than any single field can contain.
And to do it not with fear or resignation, but with that same sense of wonder and curiosity that drove Humboldt up mountains and down rivers, always looking, always connecting, always trying to see the whole.
