Alexander von Humboldt and the Invention of Nature: How One of the Last True Polymaths Pioneered the Cosmos of Connections
“In this great chain of causes and effects, no single fact can be considered in isolation.”
By Maria Popova
No thinker has shaped our understanding of the astounding interconnectedness of the universe more profoundly than the great Prussian naturalist, explorer, and geographer Alexander von Humboldt (September 14, 1769–May 6, 1859), who pioneered the notion that the natural world is a web of intricately entwined elements, each in constant dynamic dialogue with every other — a concept a century ahead of its time. His legacy isn’t so much any single discovery — although he did discover the magnetic equator, invented isotherms, and came up with climate zones — as it is a mindset, a worldview, a singular sensemaking sublimity.
Goethe, in his conversations with Eckermann, remarked that a single day with Humboldt enriched him more than years spent alone, enthusing:
What a man he is! … He has not his equal in knowledge and living wisdom. Then he has a many-sidedness such as I have found nowhere else. On whatever point you approach him, he is at home, and lavishes upon us his intellectual treasures. He is like a fountain with many pipes, under which you need only hold a vessel, and from which refreshing and inexhaustible streams are ever flowing.
Darwin asserted that Humboldt’s writings kindled in him a zeal without which he wouldn’t have boarded the Beagle or written On the Origin of Species. Thoreau was an ardent admirer of Humboldt’s “habit of close observation,” without the influence of which there might have been no Walden. Trailblazing astronomer Maria Mitchell, who met Humboldt weeks before his death, marveled in her diary that “no young aspirant in science ever left Humboldt’s presence uncheered,” and his ideas reverberate through her famous assertion that science is “not all mathematics, nor all logic, but it is somewhat beauty and poetry.” Emerson, in his essays and lectures, called Humboldt “a man whose eyes, ears, and mind are armed by all the science, arts, and implements which mankind have anywhere accumulated” and saw him as living proof that “a certain vastness of learning, or quasi omnipresence of the human soul in nature, is possible.”
In informing and impressing the greatest minds of his time, Humboldt invariably influenced the course of science and its intercourse with the rest of culture in ways innumerable, enduring, and profound. His visionary understanding of nature’s interconnected sparked the basic ecological awareness that gave rise to the environmental movement. His integrated approach to science, incorporating elements of art, philosophy, poetry, politics, and history, provided the last bold counterpoint to the disconnected and dysfunctional “villages” of specialization into which science would fragment a mere generation later. And yet Humboldt, despite his enormous contribution to our most fundamental understanding of life, is largely forgotten today.
In The Invention of Nature: Alexander von Humboldt’s New World (public library), London-based design historian and writer Andrea Wulf sets out to liberate this extraordinary man’s legacy from the grip of obscurity and short-termism, illuminating the myriad threads of influence through which he continues to shape our present thinking about science, society, and life itself.
Wulf paints the backdrop for Humboldt’s enduring genius:
Described by his contemporaries as the most famous man in the world after Napoleon, Humboldt was one of the most captivating and inspiring men of his time. Born in 1769 into a wealthy Prussian aristocratic family, he discarded a life of privilege to discover for himself how the world worked. As a young man he set out on a five-year exploration to Latin America, risking his life many times and returning with a new sense of the world. It was a journey that shaped his life and thinking, and that made him legendary across the globe. He lived in cities such as Paris and Berlin, but was equally at home on the most remote branches of the Orinoco River or in the Kazakh Steppe at Russia’s Mongolian border. During much of his long life, he was the nexus of the scientific world, writing some 50,000 letters and receiving at least double that number. Knowledge, Humboldt believed, had to be shared, exchanged and made available to everybody.
But knowledge, for Humboldt, wasn’t merely an intellectual faculty — it was an embodied, holistic presence with life in all of its dimensions. A rock-climber, volcano-diver, and tireless hiker well into his eighties, Humboldt saw observation as an active endeavor and continually tested the limits of his body in his scientific pursuits. For him, mind, body, and spirit were all instruments of inquiry into the nature of the world. Two centuries before Carl Sagan sold us on the idea that “science invariably elicits a sense of reverence and awe,” Humboldt advocated for this then-radical notion amid a culture that drew a thick line between reason and emotion.
Fascinated by scientific instruments, measurements and observations, he was driven by a sense of wonder as well. Of course nature had to be measured and analysed, but he also believed that a great part of our response to the natural world should be based on the senses and emotions. He wanted to excite a “love of nature.” At a time when other scientists were searching for universal laws, Humboldt wrote that nature had to be experienced through feelings.
Out of this integrated approach to knowledge sprang Humboldt’s revolutionary view of life — the scientifically informed counterpart to Ada Lovelace’s famous assertion that “everything is naturally related and interconnected.” Wulf captures his greatest legacy:
Humboldt revolutionized the way we see the natural world. He found connections everywhere. Nothing, not even the tiniest organism, was looked at on its own. “In this great chain of causes and effects,” Humboldt said, “no single fact can be considered in isolation.” With this insight, he invented the web of life, the concept of nature as we know it today.
When nature is perceived as a web, its vulnerability also becomes obvious. Everything hangs together. If one thread is pulled, the whole tapestry may unravel.
Given his attentiveness to this interconnectedness across all scales and dimensions of life, it is hardly surprising that Humboldt became the first scientist to admonish against the grave consequences of human-induced climate change after witnessing the environmental devastation of deforestation brought on by the spread of colonial plantations across South America in the 1800s.
Deforestation there had made the land barren, water levels of the lake were falling and with the disappearance of brushwood torrential rains had washed away the soils on the surrounding mountain slopes. Humboldt was the first to explain the forest’s ability to enrich the atmosphere with moisture and its cooling effect, as well as its importance for water retention and protection against soil erosion. He warned that humans were meddling with the climate and that this could have an unforeseeable impact on “future generations.”
We are shaped by the past. Nicolaus Copernicus showed us our place in the universe, Isaac Newton explained the laws of nature, Thomas Jefferson gave us some of our concepts of liberty and democracy, and Charles Darwin proved that all species descend from common ancestors. These ideas define our relationship to the world.
Humboldt gave us our concept of nature itself. The irony is that Humboldt’s views have become so self-evident that we have largely forgotten the man behind them. But there exists a direct line of connection through his ideas, and through the many people whom he inspired. Like a rope, Humboldt’s concept of nature connects us to him.
Wulf pulls on that rope with both hands:
There are many reasons why Humboldt remains fascinating and important: not only was his life colourful and packed with adventure, but his story gives meaning to why we see nature the way we see it today. In a world where we tend to draw a sharp line between the sciences and the arts, between the subjective and the objective, Humboldt’s insight that we can only truly understand nature by using our imagination makes him a visionary.
Humboldt’s disciples, and their disciples in turn, carried his legacy forward — quietly, subtly and sometimes unintentionally. Environmentalists, ecologists and nature writers today remain firmly rooted in Humboldt’s vision — although many have never heard of him. Nonetheless, Humboldt is their founding father.
As scientists are trying to understand and predict the global consequences of climate change, Humboldt’s interdisciplinary approach to science and nature is more relevant than ever. His beliefs in the free exchange of information, in uniting scientists and in fostering communication across disciplines, are the pillars of science today. His concept of nature as one of global patterns underpins our thinking.
It feels as if we’ve come full circle. Maybe now is the moment for us and for the environmental movement to reclaim Alexander von Humboldt as our hero.
The Invention of Nature is a riveting read in its entirety, bringing back to life the remarkable man who gave shape to life as we know it. Complement it with the equally enchanting story of Luke Howard — the young amateur meteorologist who classified the clouds and who, like his contemporary Humboldt, bewitched Goethe with his genius — then trace Humboldt’s legacy to our present-day understanding of how everything connects.
