Is Critical Naturalism Necessary?
Martine Prange, Ties van Gemert, Willem van der Deijl-Kloeg, Paolo Santori
After a collective reading and discussion of the Critical Manifesto, members of the Tilburg
Research Group Philosophy of Humanity, Culture, and Ethics (PHC&E) and Tilburg Center
for Moral Philosophy, Epistemology and Philosophy of Science (TiLPS) decided to write the
present response, combining each member’s remarks and questions. We believe that the chal-
lenges addressed by the Manifesto are pertinent and urgent. We are sceptical, however, of the
ways in which the authors address the problems and of the version of “critical naturalism” they
propose. The following four points capture some of our reservations:
1. The question is, first, what the authors mean by “critical naturalism,” since “natural-
ism” is hardly defined; and, second, what critical naturalism has to offer or add to ex-
isting theories that have been concerned with similar issues. Think, for instance, of
Braidotti’s critical posthumanism (Braidotti 2013). Think also of Latour’s thought on
the Anthropocene and his concept of “Gaia” as an ethical alternative for “Earth” or
“nature” (Latour 2017); think perhaps even of the Romantic tradition running from
Humboldt to Nietzsche, which is marked by its claim for the unity of humanity and
nature (Nietzsche 1980). The authors of the manifesto overlook these, and other, tradi-
tions, and as a result invite us to reinvent the wheel. They seem to operate from an
awareness that Critical Theory currently offers little to the (philosophical and political)
climate debates, and that any serious social critique needs to. As they claim, the human-
nature relationship needs to be rethought because, they state, the social is embedded in
nature. Naturalism, in this context, seems to mean: “critical theory turning its focus to
nature,” which makes a very meagre concept. How does this concept strengthen or defy
existing concepts from the long traditions of naturalism in both continental and analytic
philosophy? What strikes us as odd in addition to this, is that they advocate a turn to
Hegel – the giant thinker of “spirit,” to address nature. Is Hegel really a greater thinker
of nature and the humanity-nature relationship than, say, Humboldt, Nietzsche, or
Latour? In sum, it is praiseworthy that the authors try to open up a way for scholars in
the Frankfurter tradition to rethink the humanity-nature relationship in light of the cur-
rent climate crisis. The question is, however, whether we are not better off with
