What is nature?

PDF

Nature is a common notion, which everyone is familiar with as long as we are not asked to define it. This is normal: there is no consensus definition of it, and the term is rejected by most academic disciplines in both the sciences and the humanities. Yet it stays, and even better: it is eminently political – and even more so at a time when the idea of “protecting nature” is pressing. In this article, we attempt to unravel its mysteries, tracing its origin, its evolution and the succession of issues in which it has found itself in a central position. The aim is to identify the different realities it embraces, and the particular ways in which we relate to them in the era of global crises.

1. How do we define “nature”?

Few encyclopaedias have a “nature” article. The one written by Diderot and d’Alembert, in 1751, was already wary of “this rather vague term, often used, but seldom defined, which philosophers tend to use too much”, and Buffon, who was in charge of writing it, quickly abandoned the project. He was urgently replaced by d’Alembert and de Jaucourt, who only provided a timid catalogue of “its various meanings [which] are so numerous that one author can count as many as 14 or 15″ , an article consisting essentially of cross-references to terms deemed more satisfactory, albeit heterogeneous, such as “System of the world”, “Cause”, “Essence”, “Providence” and even “God” (Figure 1).

Even today, specialized encyclopaedias still seem to carefully avoid the concept of “nature”: this is for example the notable case of the Oxford Dictionary of Science (2005), but also of the Encyclopedia of environmental ethics and philosophy (2008). The Encyclopaedic Dictionary of Ecology and Environmental Sciences gives it three lines that do not say much, and the Dictionary of Ecological Thought (2015), for its part, takes the precaution of specifying its articles (“nature in philosophy”, “ordinary nature”), thus carefully circumventing the idea of nature itself – although this does not prevent its use in many articles. The same observation can be made on philosophers: nature does not stand among the “major notions of philosophy” in the main university textbooks, has never been on the syllabus of any French examination or competition, and one of the few textbooks to deal with it, André Lalande’s Vocabulaire technique et critique de la philosophie (regularly updated since 1902) imitates d’Alembert by recommending rigorous thinkers to avoid the use of this word, which can mean everything and its opposite. Moreover, the term is openly circumvented by many scientists, who prefer better defined and above all measurable hyponyms – because in the modern age there is no science without quantification – such as “biosphere”, “biodiversity”, “biocenosis”, “ecosystems” and other “physicalities” among anthropologists.

Thus, “nature” remained essentially a “casual” term in European languages, and has almost never been the subject of advanced academic theorization, except for the expression “human nature”, which had its moment of glory in the 18th century under the impetus of David Hume or Jean-Jacques Rousseau [1] (Figure 2).

Yet the ecological crisis has brought the idea of nature back to the forefront, and the word is now everywhere: this fact shows that it may not mean “nothing”, and that it is not really substitutable either. At a time when nature is said to be “in crisis”, when everyone would like to “protect” or even “act” on it, it is more imperative than ever to have a clear idea of this concept and its ramifications, which is what this article proposes to do [2].

2. Story of a mysterious word

Etymology is often an excellent way to shed light on the depth of a term; however, the term “nature” largely escapes this approach. The word is formed from the Latin verb nascor, which means “to get born”, here in a verbal form called supine, a form that can be used to construct the future participle (which does not seem to be the case here, at least no usage in this sense is known) or, like the other Latin words in -ure (culture, temperature) designates a way of being. Etymologically, it would therefore be the way in which one gets born, a kind of primordial character – which then excludes any absolute usage (effectively absent throughout the pre-classical period). In the Classical period, when young Romans from good families went to Greece to complete their intellectual education, this word was chosen to translate the Greek phusis, and became its standard translation. Phusis is one of the most complex concepts of Greek philosophy, both omnipresent (almost all the great works of the pre-Socratic philosophers are titled Peri phuseos, this concept appearing as the object of any scientific or philosophical enterprise), but with a meaning and usage that varies enormously from one author to another, or more precisely from one philosophical school to another. At the end of the apogee of Greece, Aristotle attempts a catalogue of these meanings, and lists four main ones [3]:

  • generation of that which grows;
  • the first immanent element from which growth proceeds;
  • principle of the first movement for every natural being;
  • and the primeval background from which any artificial object is made or comes from.

These four definitions could be roughly summarized as: growth, principle, power and substance. So here we are in the realm of physics – a term that is occasionally coined – and still far from biology and the environment. Greco-Roman nature does not yet designate a set of objects, but rather the dynamics that animate matter, whether living or not (the term is not often used in the Philosopher’s biology books).

It is in fact the Christianisation of Europe that will change the meaning of the word natura. Indeed, in the Christian cosmology (Figure 3), all dynamics can only come from God: it is him alone who creates the world and animates it, he is beyond nature and nothing is beyond him – whereas among the Greeks, the gods were subject to nature, they were still, in their own way, animals, animated by impulses, passions and needs. In the Abrahamic monotheisms, the whole of reality is now only a creation, a set of passive objects conceived and arranged by the demiurge, and from which only Mankind emerges, which is at once part of this creation but is called to transcend it. This hierarchy is an extremely original idea, which does not seem to be present in any other great civilizational basin: Mankind is then no longer completely a part of nature, and all the value of their existence lies in fact beyond nature, in the Kingdom of God. There is therefore no longer natura naturans, the creative principle which is a simple synonym of God, and natura naturata, which is his creation – knowing that the good Christian must despise earthly things [4], since it is through asceticism that one rises to God. The very word nature will thus become scarcely used in the Middle Ages, essentially returning to its etymological use.

It was not until the Renaissance that nature made a comeback in the European intellectual landscape, following the rediscovery of ancient texts, but without any real theorization of its meaning: nature is then seen either as the whole of creation (including Man or not), the set of physical forces that regulate the world (“natural laws”), or even a kind of abstract power of reality, sometimes allegorized in “Nature” with capital letters, a sort of earthly emissary of the divine will, even a feminine and benevolent counterpart of the Almighty Father (nature was already allegorized at the end of antiquity under the maternal figure of Isis, who was later secularized in the idea of “Mother Nature” [5]) (Figure 4). The fact that Plato, the meta-physician par excellence, does not seem to have been interested in this concept, which was too material, whereas philosophers gradually erected him during the classical age as the chief arbiter of what is or is not a philosophical concept, probably contributed later on to its scorn by most of the European academic tradition, and this until today.

3. Diversity of uses of the word

Despite this dislike of the academic world, “nature” remains the 419th most used word in the French language out of the 60,000 words listed in the usual dictionaries. It has undergone a number of one-off fashion effects, both during the Romantic period and with the cultural revolution of the 1960s and 1970s, in particular because of its fundamentally subversive nature, since the opposition between “nature” and “culture” makes it the perfect recourse when it comes to challenging the established order (“return to nature”) – even though “established order” is also precisely one of the meanings of “nature” [6]

A study published in 2020 [7] attempted to review the meanings and uses of the word “nature”, based on a review of dictionaries, some of which have as many as 20 different and often contradictory definitions. All these ramifications seem to be summarized in four main ideas:

  • The totality of material reality that does not result from human will (as opposed to artifice, intention and culture);
  • The whole universe as a place, source and result of material phenomena, including man or at least his body (as opposed to the supernatural, the metaphysical or the unreal);
  • The force at the principle of life and change (opposing inertia, fixity and entropy [8]);
  • The essence, the set of specific physical properties and qualities of an object, living or inert (opposing denaturation).

These four definitions appear extremely heterogeneous in many aspects: some include humans while others explicitly exclude them, and some refer to objects and others to abstract phenomena or characters. They can therefore form the basis for radically different or even contradictory “conservations of nature” , and even, for some, make such an idea absurd: we have grouped these definitions and what they could represent in terms of conservation in Table 1.

4. What to protect?

As we have seen, nature is multiple: it follows that its protection is also crossed by several currents, which have added up rather than succeeded each other over time, at the rate of the emergence of new issues.

4.1. Protecting nature as a set of resources

Historically, human societies first protected natural “resources” (wood, game, “useful” animals and plants…) [9], “nature” itself being too abstract and too massive to be the object of direct human action. As early as the Mesolithic period, sedentary human groups began to save part of their resources to ensure their reproduction and permanence. This management was later entrusted to specialized corporations, such as in France the Administration of Water and Forests, created by Philippe le Bel in 1291, before being modernized by Colbert in 1669. In the US, it was Gifford Pinchot (trained at the Ecole de Nancy) who was the great protector of natural resources at the end of the 19th century, faced with the increasingly ferocious appetite of loggers (Figure 5).

4.2. Protecting nature as a living environment

With sedentarisation, came along ideas of health and safety. Indeed, human settlements attracted a whole host of commensal or parasitic species, not always desirable, both animal and plant, and even bacterial. The organization of the living environment has therefore rapidly become a necessity for all human societies, notably through the extirpation of a certain number of animals declared undesirable, often by means of exogenous domestic predators (dogs, cats, mustelids, viverrids, chickens, etc.), and then by using pesticides. This development came along with the anthropisation of the landscape, firstly through morphological (canals, terraces, flattening) and vegetal (fruit trees, ornamental trees, hedges) development. This new, comfortable living environment soon came as a standard of what nature should be, but a nature here cultivated and tamed, and radically opposed to wild nature, considered hostile and dangerous. This nature is thus resolutely a socio-ecosystem, a nature thought an environment for human activities to take place in, and goes largely against other conceptions of nature. It is this ideal that Latin pastoralists called locus amoenus, a kind of natural garden (Figure 6). This ideal is indeed also found in the history of gardening, landscaping and urban planning, particularly in the 19th century with the fashion for urban parks (Hyde Park was founded in 1820, Bois de Boulogne in 1852, Central Park in 1869). As this is an ideal, we can link it to the 4th definition of nature, that of a normative archetypal state.

The protection of this nice and aesthetic natural environment is known under the particular name of environmentalism, a term that contains its anthropocentric dimension very well, and which should be distinguished from ecologism. In fact, it is above all a question of protecting humans, first against wild nature and then rapidly against human nuisances themselves: it is in this respect that various regulations of these nuisances appeared, whether it be the creation of sewers and latrines in ancient times, then more important measures with the Industrial Revolution (Figure 7): in France, for example, the Imperial Decree of 15 October 1810 relating to “Manufactures and Workshops which spread an unhealthy or inconvenient odour“, and in England the creation in 1815 of the Commons Open Spaces & Footpaths preservation society. Most of the first environmental laws fall within this framework, and protect a very specific “nature”, which is domesticated nature seen as Mankind’s support – and is not necessarily less legitimate for all that.

4.3. Protecting nature as a set of monuments and landscapes

The idea of nature underwent a revolution in the 18th century: Westerners then finished mapping the entire planet, which suddenly seemed surprisingly small. At the same time, explorers gave an idea of the spatial distribution of the different species, making it possible to understand that some of them had indeed irretrievably disappeared, whereas until then one could always imagine residual populations (even for fossil species, Figure 8). One thus becomes aware that God does not seem to “re-create” his creations if Men destroy them, and the relationship with nature then changes abruptly with the first romantic generation: nature then passes from the mysterious mother of infinite abundance to the fragile battlefield of the human history.

It was thus in the 19th century and under the effect of the industrial revolution that the idea of “protecting nature” gradually germinated in the West – and this time it was mainly artists, intellectuals and writers who contributed to this movement, such as Charles Beauquier in France or John Muir in the United States. The fourth definition will essentially be used again: protection concerns the archetypal state of a site, which we will try to preserve as it is and make it a monument, under various administrative designations (national park, natural monument, classified site, etc.). It is therefore mainly spectacular landscapes and biological or geological features that are protected at that time, from the Yellowstone geysers (Figure 9) to the colonial hunting reserves, along with the Fontainebleau forest, which obtained protection in 1861 thanks to the naturalist painters of the Barbizon school, coined as an “artistic series”, since it was the last place around Paris where one could still admire very old trees. This “nature” is therefore essentially a landscape setting that will be protected, but this time not for direct use as a living environment, but for a rarer aesthetic and intellectual use. There is also the idea that these places must be protected from the defilement of civilization, joining for the occasion the first definition, which will be taken to extremes in America, where wilderness will be seen as an image of paradise precisely because it has remained as God created it, and not corrupted by the activity of men [10]. At the same time, the birth of nationalist currents will anchor this protection of the natural heritage in a particularly marked approach to identity [11]. The protection of emblematic species followed at the end of the 19th century in a very similar fashion.

4.4. Protecting nature as a set of ecosystems

It was not until the emergence of the ecosystem concept in 1935 that the vision of “nature” as a scientific object was renewed, first as a scientific object and then as an object of conservation. While the conservationist tradition was resolutely fixist and attached itself to inert or little changing objects (or at least treated as such), a more dynamic vision of nature was to develop under the impetus of Darwin, and restore the prestige of the third definition we have given. One of the guardian figures of this transition is the famous American forester Aldo Leopold, author of a posthumous work (A Sand County Almanac, 1949) considered as the “bible” of American ecology (Figure 10). Although Leopold was still unfamiliar with the term ecosystem, he nonetheless called for the active conservation of “biotic communities”, later (1992) renamed “biodiversity“. Leopold contributed to the creation of undeveloped forest reserves, protected not for aesthetic or touristic reasons but clearly for their biological and ecological importance, in contrast to the national parks, which until then had been almost all located in arid or mountainous areas.

This new protection of nature seen as a set of ecosystems is therefore based this time on essentially scientific criteria, such as biodiversity, endemism and ecological functionalities – leading to the christening of “ordinary nature” in conservation, since the major functions rely for a large part on the most abundant species [12]. Abstract notions of biological functions, material flows of matter (water, carbon, nitrogen) and energy will also come into play, and their importance for human societies will be embodied in 2005 by the concept of  “ecosystem services“, popularized by the Millennium Ecosystems Assessment report commissioned by the UN in 2000. Nature is thus no longer inert and passive, and is becoming a platform for exchanges between biotic communities, of which humanity is one actor among others, powerful but also fragile and dependent.

4.5. Protecting nature as a set of conditions favourable to life as we know it

The scale changed radically at the end of the twentieth century: it was no longer a question of protecting objects, but rather phenomena, on an ever-increasing scale, and finally on a global scale. The very idea of reserve finds its limits here, since these flows and phenomena overflow them largely, and it is therefore the whole organization of human societies that needs to be reviewed, because this protection can no longer be satisfied with a handful of desert or mountainous areas that are sanctuarized because they were unproductive anyway. The climate, the circulation of water and the balance of biodiversity depend less on Yellowstone Park or the Monument Valley than on the use of the fertile soils of the great river plains where all human activities are concentrated, and the artificial separation of nature and humans seems quite illusory [14] (Figure 11).

The new challenge of nature conservation in the 21st century will therefore be to protect nature at the very heart of anthropized spaces, which now largely dominate the planet and, above all, the flows of matter that pass through it – this is what some call the “anthropocene” [15]. In addition to the careful protection of the last remaining unexploited ecosystems, this new nature conservation must also focus on socio-ecosystems, inhabited by a great diversity of human, non-human, living and non-living agents, all of which maintain complex relationships (read: Biodiversity is not a luxury, but a necessity). One of the approaches dealing with this new nature is called “ecology of reconciliation[16], which aims to make anthropized spaces favourable to biodiversity, through a whole series of techniques and developments. Agriculture must also be rethought so that it no longer forms monospecific deserts saturated with toxic agents, but rather harbors biodiversity that maintains the quality of the soil, the health of the plantations and that of the people who live there [17].

In addition to the technical and administrative challenge, we are therefore witnessing a real philosophical revolution: nature is no longer “outside” Man, and the boundaries between the attention paid to nature and to human populations, hitherto strictly separated in the West between material sciences and human sciences, are fading. This epistemological upheaval is therefore logically accompanied by a new philosophical production, marked in the US by academics such as J. Baird Callicott or in France by authors such as the anthropologist Philippe Descola, the sociologist Bruno Latour, the philosopher Catherine Larrère, grouped together under the label of “environmental humanities“.

5. Messages to remember

  • The concept of “nature” is particularly complex to grasp, and has evolved substantially over its history. Even today, four main definitions of nature can be identified, which are extremely heterogeneous and often contradictory; nature would be :
    • The totality of material reality that does not result from human will (as opposed to artifice, intention and culture)
    • The whole universe as a place, source and result of material phenomena, including man or at least his body (as opposed to the supernatural, metaphysical or unreal)
    • The force at the core of life and change (opposing inertia, fixity and entropy)
    • The essence, the set of specific physical properties and qualities of an object, living or inert (opposing denaturation).
  • The idea of “protecting naturevaries enormously depending on the reference frameworks used, and various traditions of nature protection have developed over time, with distinct, and here too, readily contradictory objects, techniques, concepts and objectives.
  • The very vagueness that surrounds the idea of nature prevents its recuperation by a particular disciplinary field (philosophy, biology, politics…) and thus forces the sciences and institutions to confront a popular word rich in varied connotations, conveying many social affects.
  • This diversity prevents the idea of technocratization by preserving a diversity of choices and opportunities open to democratic dialogue.
  • In this article, only the “Western” concept of nature has been discussed, but its equivalents (or lack of equivalents) in other languages have been the subject of a study published in 2020 [18].
