Our present situation of anthropogenic ecological disaster calls on Western philosophy in general, and Frankfurt School critical theory in particular, to reconsider some long-standing, entrenched assumptions concerning what it means to be a human agent and to relate to other agents. In my article, I take up the challenge in dialogue with the idea of critical theory articulated by Max Horkheimer in the 1930s. My overall concern is to contribute to on-going efforts to decentre Frankfurt School critical theory in multiple (...) dimensions. With the help of Horkheimer, I seek to show that this theoretical tradition has itself an important contribution to make to the endeavour. In Section 1, I argue that the methodology he advocates for critique of society offers a view of the relationship between the human mind and reality, as well as of humans with other humans, that avoids dogmatic rigidity and is hospitable towards mutual learning through engagement with other philosophical and cultural traditions. In Section 2, I consider the more specific challenge of anthropocentrism, suggesting the need for a more differentiated account of this. While critical theory is unavoidably anthropocentric in certain respects, it could avoid more pernicious forms of anthropocentrism that establish epistemic and ethical hierarchies between humans and other-than-human entities and that conceive of ethical validity as a purely human construction, with no independence of human needs and concerns.
