Abstract
This essay considers the catastrophe of anthropogenic climate change in relation to two possible critical-theoretic dispositions. The first, represented by an emblematic passage from Adorno, retains the hope for the realization of a "rational society." The second, represented by a complementary passage from Foucault, enjoins critical theory to abandon any ambition toward criticizing or transforming society at a totalizing level. We argue that the unfolding climate catastrophe demands a conception of critical theory more in line with the first disposition, and that the relevance of the skeptical disposition is likewise seriously undermined if climate change is taken into account.
