Three Great Decenterings of Humanity

Discussion

Jonathan Zawada:

"The concept of Planetarity describes a new condition in which humans recognize not only that we are not above and apart from “nature,” but that we are only beginning to understand the complexities of our interdependencies with planetary systems.

“If Copernicus’s heliocentrism represented the First Great Decentering, displacing the Earth from the center of the heavens, and Darwin’s theory of evolution by natural selection the Second Great Decentering, then the emergence of the concept of the Planetary represents the Third Great Decentering, and the one that hits closest to home, supplanting the figure of the human as the measure and master of all things,” Blake and Gilman write.

As further argued by the authors in a forthcoming Berggruen Press volume, “the Planetary as a scientific concept focuses on the Earth as an intricate web of ecosystems, with myriad layers of integration between various biogeochemical systems and living beings — both human and non-human. Drawing on earth system science and systems biology, this holistic understanding is being enabled by new planetary-scale technologies of perception – a rapidly maturing technosphere of sensors, networks, and supercomputers that collectively are rendering the planetary system increasingly visible, comprehensible and foreseeable. This recently-evolved smart exoskeleton — in essence a distributed sensory organ and cognitive layer — is fostering an unprecedented form of planetary sapience.”
