If often denied and repressed, the Anthropocene has returned naturalism to the center of the possibility of social philosophy. In this splendid and timely series of essays, the classical defenders of naturalism in social theory—from Hegel and Nietzsche through to Dewey, Beauvoir, Wittgenstein, Adorno and Horkheimer—are provided with emphatic elaboration and defense. Singularly and collectively, these essays demonstrate the defining characteristics of the kind of naturalism necessary for a Critical Theory of society today.
