The role of metaphysics in critique stands as a defining issue for the Frankfurt School theorists. Max Horkheimer himself claims that metaphysics serves as an instrument of domination, leading him to develop an interdisciplinary mate- rialism as a postmetaphysical alternative. Critics such as Georg Lohmann con- tend, however, that Horkheimer’s critique of instrumental reason is aporetic insofar as it undermines all metaphysical claims while implicitly making them. Since Horkheimer narrowly equates metaphysics with identity thinking, this article argues that his appeal to nonidentity thinking as the foundation for critique is better understood as a form of antimetaphysics. This, however, leaves Horkheimer no better situated, since antimetaphysics remains a variant of metaphysics. While Horkheimer reproduces the techniques of domination he sought to avoid, this lapse into metaphysics warns of the difficult path that postmetaphysical thinking must navigate between the antipodes of metaphys- ical and antimetaphysical positions.

In this article, Shea aims to overturn Jürgen Habermas’s characterization of Nietzsche in The Philosophical Discourse of Modernity as a postmodern irrationalist. On Habermas’s account, Nietzsche employs Wille zur Macht both as a principle by which to invalidate the claims of metaphysics and as a primordial “other” to reason that unmasks reason as an expression of domination. If Habermas’s reading is correct, Nietzsche’s work is ultimately incoherent since it either lapses back into metaphysics or puts forward a self-refuting anti-metaphysics. Contrary to Habermas, Shea argues that Nietzsche’s theoretical inquiries result from a considered methodological decision on the part of Nietzsche to suspend metaphysical interpretations. For this reason, Wille zur Macht can be read as the fabrication of a post-metaphysical principle for interpreting life rather than as a purported insight into the ultimate nature of reality and thus as a genuine alternative to the trappings of both metaphysical and anti-metaphysical philosophies.

While traces of a post-metaphysical political theory are to be found throughout his oeuvre, Nietzsche himself never explicitly elaborates any such comprehensive theory. Yet, this chapter argues, it is possible to discern a politics beyond ressentiment and the ascetic ideal, which must be both experimental and pluralist. Inspired by Nietzsche, Foucault thinks the political as a play of force relations immanent to a concrete strategic field, and thus as a multiplicity of power relations existing in agonistic tension rather than as a duality in antagonistic opposition. This makes him one of the most significant inheritors of the Nietzschean challenge to overcome the politics of ressentiment and to think instead a politics of affirmation that makes difference constitutive of the political.
