In the French eighteenth century, it is difficult to understand how science worked without first studying its relationship to written language. Language was not only a way to communicate ideas. It was the foundation of worlds both real and imagined: it comprised the building blocks of both human nature and of external nature. Things in the world existed because people named, ordered and narrated them. Nature could be studied because it was, in large part, an invention of the human mind; its workings became legible, predictable, scientific because they had been captured in language. In the Encyclopédie, Denis Diderot asked: ‘What difference would there be between the reading of a work in which all the motives of the universe are explored, and the very study of the universe? almost none.’ 
The French natural historian Georges Louis Leclerc de Buffon thought in a similar manner, proposing in his 1778 ‘Des époques de la nature’ (just recently translated into English!) to recount the great eras of natural history ‘as they are or as they could be: for these two points of view are practically the same.’  He wrote as if he had personally observed the work of nature since the birth of the planet Earth, and the imagined or hypothetical story was to be considered as good as, if not better than, the first-hand experience of observation. My book traces this curious assumption, which can sound quite foreign in the light of modern scientific practice, but which begins to make sense when science is understood as itself a language. The discipline of natural history, in particular, was rigorously redefined by Buffon in the 1750s in terms of the creation of relationships (‘rapports’) between the mind and the world in the form of written expression.
Buffon believed that the more the historian studied nature, dedicating time and thought to understanding its order and operation, the more his or her language would come to resemble the world. Nature could be reproduced in words, and soon words could come to stand in the place of nature. The idea of a new, written nature became ever more important to Buffon’s work through the 1760s and 1770s, when he suggested that real nature was losing energy and slowly dying. It needed to be replaced with the human idea of nature. This was no longer simply the story of the past eras of natural history or of the regularity of natural law: it was a vision of a future where the art of human language and the artificiality of human landscapes would become the new natural. Humans gained the ability, right, and obligation to control and change nature because they had appropriated its language. In ‘Des époques de la nature’ Buffon imagined the world devoid of what he thought to be terrifying wild animals, rugged and inhospitable forests, and cold, uninhabitable swamps. Once people could speak like nature, they could possess it and transform it into a temperate garden, a terrestrial Eden.
After finishing the final chapter of the book, about the human control of nature and the creation of what Buffon considered to be a ‘better world’ through language, I began to think more about the continued influence of the Enlightenment on modern-day thought. It is crucial to understand eighteenth-century attitudes and theories such as Buffon’s about nature in order to see better the assumptions made in Western societies about the environment and its relationship to people. These are not only assumptions about dominating, taming, and taking control of nature for the good of human survival, industry, science, and culture. There is also the underlying belief that the relationships between humans and the natural world are intrinsically part of a story. They must be made to fit into and justify the arc of an inevitable narrative with a clear beginning, end, structure, and chain of causality linking all parts together (examples of such narratives and how to approach their study are examined in the recent publication Anthropocene Reading, for instance). The language of this story was, for Buffon, a series of keys that would eventually unlock the meaning of the past and the implications or predictions for the future.
The underlying motifs of Buffon’s story were the slow death of nature as it lost its initial heat and energy, and the opposing, active force of humankind as it worked to hamper this heat death by conquering nature and changing, taming, subduing it. Buffon in fact begged for global warming: he encouraged people to cut down forests, to burn fallow land, to dry up swamps. This idea became part of the narrative of industrialization in Western culture, and it is still present as society considers what it has done to the world and how to mediate the world’s end. Buffon’s narrative is an upsetting one – but it raises the issue of the value of a story, of the necessity of inventing a new narrative of nature to which to aspire, and of the uses, implications, and dangers of fiction in the modern sciences.
