The Natural Contract opens with a typical Serresian flourish: a description of a harrowing scene painted by Francisco Goya (1746-1829). Two men are fighting each other with clubs, knee-deep in a quagmire of mud. The outcome of the brawl seems clear: both antagonists will perish. The more violently they clash, the more quickly they will be swallowed by the quicksand.
In Serres' reading this scene becomes a layered allegory for the relationship between humankind and its planetary habitat. Armed conflict has been the engine of history. However, war is not merely a 'primitive' state of men going down by the hand of other men. War is a (de jure) process that takes place within a legal framework: declaration, conflict, armistice. This framework was born from necessity as it put the lid on an endless cycle of vengeance. Serres hypothesises that there lies the origin of the social contracts that regulate societies. He then proceeds, characteristically, by zooming out and bringing into focus the silent, unnoticed background against which armed conflict has always taken place. The mud in Goya's painting symbolises this background. This is quite simply the world which now makes itself felt in response to the increasing weight of human presence on earth. Foreground and background are swept up in reinforcing feedback mechanisms: the more fiercely we compete, the more assertively earth makes itself felt. 'Subjective violence' engenders 'objective violence'. A new condition announces itself for humanity, a limit state of history. Serres: "We must therefore, once again, under threat of collective death, invent a law for objective violence. We find ourselves in the same position as our unimaginable ancestors when they invented the oldest laws, which transformed their subjective violence, through a contract, into what we call wars. We must make a new pact, a new preliminary agreement with the objective enemy of the human world: the world as such." This is the natural contract. Indeed, "we must decide on peace amongst ourselves to protect the world, and peace with the world to protect ourselves."
In the second part of the book Serres builds on this opening gambit. Contracts are systemically distinctive artefacts. They have a homeostatic function. Contracts canonize, thingify and stabilize relationships. They acknowledge an essential equality between signatories, codify obligations, and seek to balance interests of the parties. Similarly, "the natural contract recognises and acknowledges an equilibrium between our current power and the forces of the world."
The third essay reframes the envisioned equilibrium as a new stage in the relationship between science and law, reason and judgment. The project of scientific reason seeks limitless freedom to deploy itself. Human laws, at the service of various powers that be, have tried to curb this expansionist drive. The trial against Galilei was just one telltale flashpoint in a long conflictual relationship. However, the growing power and efficacy of the exact sciences were able to overrule this situation. Reason rose above judgment. Today, in the context of a global pandemic, we acquiesce when scientists advise politicians to sidestep constitutional rights. Serres suggests that our predicament invites us to think differently here. Rather than one dominating the other, reason and judgment have to enter into a positive cycle. "Thus it is better to make peace by a new contract between the sciences, which deal relevantly with the things of the world and their relations, and judgment, which decides on humans and their relations. It is better to make peace between the two types of reason in conflict today, because their fates are henceforth crossed and blended and because our own fate depends on their alliance. Through a new call to globality, we need to invent a reason that is both rational and steady, one that thinks truthfully while judging prudently."
At this point Serres introduces a new character, The Troubadour of Knowledge, which will turn to be the protagonist in his next book, Le Tiers-Instruit, published in 1991. The Troubadour models this hybrid reason with courage and wisdom. (S)he is the product of a process of education that gave her the courage to expose herself, to cast herself off. Listen how eloquently Serres brings the third essay of the Natural Contract to a close:
"We must learn our finitude: reach the limits of a non-infinite being. Necessarily we will have to suffer, from illnesses, unforeseeable accidents or lacks; we must set a term to our desires, ambitions, wills, freedoms. We must prepare our solitude, in the face of great decisions, responsibilities, growing numbers of other people; in the face of the world, the fragility of things and of loved ones to protect, in the face of happiness, unhappiness, death. To deny this finitude, starting in childhood, is to nurture unhappy people and foster their resentment of inevitable adversity. We must learn, at the same time, our true infinity. Nothing, or almost nothing, resists training. The body can do more than we believe, intelligence adapts to everything. To awaken the unquenchable thirst for learning, in order to live as much as possible of the total human experience and the beauties of the world, and to persevere, sometimes, through invention: this is the meaning of equipping someone to cast off."
This might have been a fitting conclusion to Serres' ruminations on the contract with Nature. But he presses on with a moving meditation on the experience of 'casting off' and the role of cordiality, concord, contract in navigating that transition into a new world. The philosopher conjures unforgettable images: a ship that unmoors in the port of Brest while a couple - woman on the quay, man on the departing vessel - continue to be connected by the graceful parabolas traced by an apple exchanged between them; the launch of spacecraft Ariane from its base in a rainforest; the pre-dawn departure of a party of mountaineers from a high hut in the Alps. The cord that ties the climbers together becomes a powerful simile for the relational import of the contract: "The term contract originally means the tract or trait or draft that tightens and pulls: a set of cords assures, without language, the subtle system of constraints and freedoms through which each linked element receives information about every other and about the system, and draws security from all."
Today our technologies offer a system of cords, of exchanges of forces and information with the Earth. We ceaselessly inform with our movements and energies, and the Earth, in return, informs us of its global change. For better of for worse, we are doomed to live contractually with the Earth. This demands vigilance and diligence, a decisive break with our contemporary negligence. It also demands a rekindling of love, for our mother. In the book's final pages, the philosopher bursts into a paean to the painfully beautiful manifestation of pure potentiality: "Indescribable emotion: mother, my faithful mother, our mother who has been a cenobite for as long as the world has existed, the heaviest, the most fecund, the holiest of material dwellings, chaste because always alone, and always pregnant, virgin and mother of all living things, better than alive, irreproducable universal womb of all possible life, mirror of ice floes, seat of snows, vessel of the seas, rose of the winds, tower of ivory, house of gold, Ark of the Covenant, gate of heaven, health, refuge, queen surrounded by clouds, who will be able to move her, who will be able to take her in their arms, who will protect her, if she risks dying and when she begins her mortal agony? Is it true that she is moved? What have we not destroyed with our scientific virtuosity?"
