There are two sides to Adorno’s idea of natural history: showing that what appears to be natural is in fact subject to social change, while exposing social change as recurrence of the ever same. Focusing on the second side, this article explains how such a naturalisation can contribute to social critique. What distinguishes Adorno’s use of biological vocabulary from social Darwinism is the critical intention. Rather than scorning nature, naturalisation starts with the conventional notion of nature in order to unmask (...) it as a projection. ‘Nature’ in this sense is what we refuse to acknowledge about our own history. In so far as it does not establish any ontological claims about nature but aims at social transformation, Adorno’s strategy can be understood as a critical naturalism. In the process of demonstrating how human practices are part of nature, the underlying concept of nature is being transformed. (shrink)
