In this article, I argue that the concept of alienation should be mobilized to develop a ‘geo-social’ critique of the generic forms of life that sustain contemporary capitalist societies, in a time when the stability of the Earth system is increasingly at risk. I contend that retrieving the full heuristic potential of the concept demands engaging the fields where it has been traditionally discussed (notably social philosophy and environmental philosophy) to demonstrate how their insights on alienation can be fruitfully combined. (...) By putting greater emphasis on how society and nature are mutually embedded, this new approach to alienation highlights the anthropocentrism that critical theory has long conveyed and indicates how it could be at least partially corrected.
