Our twentieth century has a forgotten Galileo. Sure, you learn appropriately. And the affirmation doesn’t come from an obscure disciple, however from a luminary of ecological thought: the thinker Bruno Latour himself. This up to date Galileo is known as James Lovelock, a British chemist who died in 2022, on the age of 103. “To the Earth that strikes from Galilee, to be full, it was essential so as to add the Earth that strikes from Lovelock”marveled Bruno Latour, not in a social community put up, however in his nice e-book of ecological reflection Going through Gaia (The Discovery, 2015).
In the identical gesture, he celebrates this sulfurous engineer as a visionary and imposes on the coronary heart of latest thought the curious object that’s Gaïa, whose success is commensurate with the controversies it has aroused since its formulation, there half a century in the past. Denounced by biologists as unscientific, the Gaia speculation has however permeated all Earth sciences. Criticized for the reactionary considering of its creator, it concurrently modified the outlook on the character of the planet, inspiring main ecological ideas, from ecofeminism to these of the Belgian philosophers Isabelle Stengers and the French Bruno Latour.
The founding article appeared in 1974, within the scientific journal Earth. James Lovelock indicators it with Lynn Margulis (1938-2011), American microbiologist with whom he’ll develop his speculation. “The full assortment of residing organisms that represent the biosphere can act as a single entity to manage chemical composition, floor pH and presumably local weather”formalize the 2 researchers.

As easy in its formulation as incalculable in its implications, their imaginative and prescient affords one other means of conceiving planet Earth and the life it shelters. All the pieces begins from a reversal of perspective. Of their eyes, the floor of the Earth is not populated by a mess of species, however constitutes a totality forming a system with properties which can’t be summed up by the addition of what makes it up. As if life shaped a big creature that might unfold throughout the biosphere, the ambiance, the oceans and the soil, and would have formed the Earth to make it appropriate for its existence.
The instinct of this huge “residing creature” involves them from three observations. Organic: residing beings can solely dwell in very exact physicochemical circumstances (pH, temperature, composition of the ambiance, and so forth.), exterior of which life would disappear, and which have persevered for a number of billion years. Geological: life has deeply formed its terrestrial setting, suggesting that the biosphere kinds a “machine too highly effective” to be solely passive. Climatic: a number of examples counsel that regulation made it attainable to cushion circumstances that might have extinguished life – such because the decrease preliminary luminosity of the solar, which didn’t end in huge glaciation. For Lovelock and Margulis, every part converges to suppose the existence of a mega-organism which might have allowed life a stability defying billions of years.
