The term “Anthropocene” designates the present age of the world, dominated and transformed by human activity. It is therefore an age of crisis, whose central features include not only technological exploitation of the earth, but also a loss of faith in any order, natural or supernatural, that could serve as a guide to human affairs. In this essay, I wish to argue, first, that the roots of this crisis rest with the modern concept of nature, a concept of nature that, as Hans Jonas wrote, “contained manipulability at its theoretical core.”
