Abstract

This article offers a response to massive environmental destabilization by linking the promising accounts of intergenerational justice as turn-taking with the proposals for a geokinetic view of earth and the idea of a second Copernican revolution. The argument will proceed in four steps. First, I suggest that recent proposals calling on us to respond to the Anthropocene by ‘being geologically human’, that is, by situating lived human time in geological time, should be supplemented by generational time, and thus, by the ethics of human generations following one another. To conceptualize intergenerational justice, I review the proposals for human generations taking turns with the earth. I then suggest that, however, the earth is not an external, exchangeable object of turn-taking (as e.g. a bicycle would be). Rather than being an object that we may choose to use or not, earth is constitutive of generations being able to come about and take turns in the first place. In this constitutive sense, earth also takes turns with us. To further specify this idea, I discuss the so-called ‘second Copernican revolution’, according to which the earth not only moves around the sun, but is internally on the move, its geokinetic processes co-constituting human generations. If the argument goes through, the environmental crises in our very midst should be understood as demanding a reconceptualization of time as always already intergenerational and space as counter-Copernican.
