The Invention of Nature: Alexander von Humboldt's New World

Knowledge, Humboldt believed, had to be shared, exchanged and made available to everybody.

Nature is the domain of liberty,’ Humboldt said, because nature’s balance was created by diversity which might in turn be taken as a blueprint for political and moral truth. Everything, from the most unassuming moss or insect to elephants or towering oak trees, had its role, and together they made the whole. Humankind was just one small part. Nature itself was a republic of freedom.

The effects of the human species’ intervention were already ‘incalculable’, Humboldt insisted, and could become catastrophic if they continued to disturb the world so ‘brutally’. Humboldt would see again and again how humankind unsettled the balance of nature.

Humboldt ‘read’ plants as others did books – and to him they revealed a global force behind nature, the movements of civilizations as well as of landmass. No one had ever approached botany in this way.

Nature itself was a republic of freedom.

Without a diversity of opinion, the discovery of truth is impossible,’ he

Humboldt wrote about the destruction of forests and of humankind’s long-term changes to the environment. When he listed the three ways in which the human species was affecting the climate, he named deforestation, ruthless irrigation and, perhaps most prophetically, the ‘great masses of steam and gas’ produced in the industrial centres. No one but Humboldt had looked at the relationship between humankind and nature like this before.

Humboldt was the first to relate colonialism to the devastation of the environment. Again and again, his thoughts returned to nature as a complex web of life but also to man’s place within it. At the Rio Apure, he had seen the devastation caused by the Spanish who had tried to control the annual flooding by building a dam. To make matters worse, they had also felled the trees that had held the riverbanks together like ‘a very tight wall’ with the result that the raging river carried more land away each year. On the high plateau of Mexico City, Humboldt had observed how a lake that fed the local irrigation system had shrunk into a shallow puddle, leaving the valleys beneath barren. Everywhere in the world, Humboldt said, water engineers were guilty of such short-sighted follies. He debated nature, ecological issues, imperial power and politics in relation to each other. He criticized unjust land distribution, monocultures, violence against tribal groups and indigenous work conditions – all powerfully relevant issues today. As a former mining inspector, Humboldt had a unique insight into the environmental and economic consequences of the exploitation of nature’s riches. He questioned Mexico’s dependence on cash crops and mining, for example, because it bound the country to fluctuating international market prices. ‘The only capital,’ he said, that ‘increases with time, consists in the produce of agriculture’. All problems in the colonies, he was certain, were the result of the ‘imprudent activities of the Europeans’.

Nature is a living whole,' he later said, not a 'dead aggregate'. One single life had been poured over stones, plants, animals and humankind. It was this 'universal profusion with which life is everywhere distributed' that most impressed Humboldt. Even the atmosphere carried the kernels of future life - pollen, insect eggs and seeds. Life was everywhere and those 'organic powers are incessantly at work', he wrote. Humboldt was not so much interested in finding new isolated facts but in connecting them. Individual phenomena were only important 'in their relation to the whole', he explained.

Humboldt wrote that nature had to be experienced through feelings

We can never know how wide a circle of disturbance we produce in the harmonies of nature when we throw the smallest pebble in the ocean of organic life,’ Marsh wrote.

Nature every where speaks to man in a voice,’ Humboldt said, that is ‘familiar to his soul’.

After an early breakfast of black coffee – ‘concentrated sunshine’, as Humboldt called it – he worked all day and in the evening went on his usual tour of salons until 2 a.m. He

In the late eighteenth century scientists had begun to suggest that the earth must be older than the Bible, but they couldn’t agree on how the earth had formed.

Humboldt was the ‘greatest of the priesthood of nature’, Marsh said, because he had understood the world as an interplay between man and nature – a connection that would underpin Marsh’s own work because he was collecting material for a book that would explain how humankind was destroying the environment.

In Views of Nature Humboldt conjured up the quiet solitude of Andean mountaintops and the fertility of the rainforest, as well as the magic of a meteor shower and the gruesome spectacle of catching the electric eels in the Llanos. He wrote of the ‘glowing womb of the earth’ and ‘bejewelled’ riverbanks. Here a desert became a ‘sea of sands’, leaves unfolded ‘to greet the rising sun’, and apes filled the jungle with ‘melancholy howlings’. In the mists at the rapids of the Orinoco, rainbows danced in a game of hide-and-seek – ‘optical magic’, as he called it. Humboldt created poetic vignettes when he wrote of strange insects that ‘poured their red phosphoric light on the herb-covered ground, which glowed with living fire as if the starry canopy of heaven had sunk upon the turf’.

Then, in the late summer of 1790, Humboldt began to study finance and economics at the academy of trade in Hamburg. He hated it for it was all numbers and account books. In his spare time, Humboldt delved into scientific treatises and travel book, he learned Danish and Swedish - anything was better than his business studies. Whenever he could, he walked down to the River Elbe in Hamburg where he watched the large merchant vessels that brought tobacco, rice and indigo from the United States. The 'sight of the ships in the harbour', he told a friend, was what held him together - a symbol of his hopes and dreams. He couldn't wait to be finally the 'master of his own luck'.

Unlike Christopher Columbus or Isaac Newton, Humboldt did not discover a continent or a new law of physics. Humboldt was not know for a single fact or a discovery but for his worldview. His vision of nature has passed into our consciousness as if by osmosis. It is almost as though his ideas have become so manisfest that the man behind them has disappeared.

French scientists feared that Paris was going to lose its status as a centre for innovative scientific thinking. At the Académie des Sciences, Humboldt said, the savants did little and what little they did often ended in quarrels. Even worse, the scholars had formed a secret committee to sanitize the library there – removing books that propounded liberal ideas like those written by Enlightenment thinkers such as Jean-Jacques Rousseau and Voltaire. When the childless Louis XVIII died in September 1824 his brother Charles X, the leader of the ultra-royalists, became king. All those who believed in liberty and in the values of the revolution knew that the intellectual climate could only become more repressive.

Nature must be experienced through feeling,’ Humboldt

but later English Romantics such as Samuel Taylor Coleridge and American Transcendentalists such as Ralph Waldo Emerson would declare that man had once been one with nature – during a long vanished Golden Age. It was this lost unity that they strove to restore, insisting that the only way to do so was through art, poetry and emotions. According to the Romantics, nature could only be understood by turning inwards.

In Views of Nature Humboldt showed how nature could have an influence on people’s imagination. Nature, he wrote, was in a mysterious communication with our ‘inner feelings’. A clear blue sky, for example, triggers different emotions than a heavy blanket of dark clouds. Tropical scenery, densely filled with banana and palm trees, has a different effect than an open forest of white-stemmed slender birches. What we might take for granted today – that there is a correlation between the external world and our mood – was a revelation to Humboldt’s readers. Poets had engaged with such ideas but never a scientist.

With this Humboldt brought together the external physical world with the internal world of the mind. Humboldt’s Cosmos was about the relationship between humankind and nature, and Thoreau placed himself firmly into this cosmos. At Walden Pond, he wrote, ‘I have a little world all to myself’ – his own sun, stars and moon. ‘Why should I feel lonely?’ he asked. ‘Is not our planet in the Milky Way?’ He was no more lonely than a flower or bumblebee in a meadow because like them he was part of nature. ‘Am I not partly leaves and vegetable mould myself?’ he asked in Walden.

Im Gegensatz zu Christoph Kolumbus und Isaac Newton entdeckte Humboldt keinen Kontinent und kein neues physikalisches Gesetz. Humboldts Ruhm beruhte nicht auf einer bestimmten Tat oder Erfindung, sondern auf seiner Sicht der Welt.

El 14 de octubre, las tropas de Napoleón aniquilaron al ejército prusiano en dos batallas, en Jena y Auerstädt.

Fue allí, en el lago Valencia, donde Humboldt desarrolló su idea del cambio climático provocado por el ser humano. Cuando publicó sus notas, no dejó duda alguna sobre lo que pensaba:"Cuando los bosques se destruyen, como han hecho los cultivadores europeos en toda América, con una precipitación imprudente, los manantiales se secan por completo o se vuelven menos abundantes. Los lechos de los ríos, que permanecen secos durante parte del año, se convierten en torrentes cada vez que caen fuertes lluvias en las cumbres. La hierba y el musgo desaparecen de las laderas de las montañas con la maleza, entonces el agua lluvia ya no encuentra ningún obstáculo en su camino: y en vez de aumentar poco a poco el nivel de los ríos mediante filtraciones graduales, durante las lluvias abundantes forma surcos en las laderas, arrastra la tierra suelta y forma esas inundaciones repentinas que destruyen el país.

When Humboldt later instigated a German translation of Voyage of the Beagle, Darwin wrote to a friend, ‘I must with unpardonable vanity boast to you.

it didn’t matter how far one journeyed ‘but how much alive you are’.

Nature, Humboldt realized, was a web of life and a global force. He was, a colleague later said, the first to understand that everything was interwoven as with ‘a thousand threads’. This new idea of nature was to change the way people understood the world.

Humboldt later put it succinctly: ‘The wooded region acts in a threefold manner in diminishing the temperature; by cooling shade, by evaporation, and by radiation.
