ABSTRACT What is “critical” about critical theory? I claim that, to be “critical enough”, critical theory’s future depends on being able to handle today’s planetary climate crisis, which presupposes a philosophy of nature. Here, I argue that Axel Honneth’s vision of critical theory represents a nature denial and is thus unable to criticize humans’ instrumentalization as well as capitalism’s exploitation of nature. However, I recover what I take to be a missed opportunity of what I term as the early Honneth’s (...) original ecological insight, which I reconstruct precisely as a philosophy of nature. Consequently, I identify what I describe as an ecological sensibility in Honneth. This refers to a bodily capability through which humans sensuously can resonate, communicate, and interact – and through that morally engage – with nature in its entire complexity. Furthermore, by virtue of this ecological sensibility, humans can recognize nature’s inherent moral value as a sensuously affected party. Then, the early Honneth’s original insight is recovered as a critical political ecology, which is needed facing today’s climate crisis. (shrink)
