This chapter first analyses Meillassoux’s critique, in After Finitude, of subject-object correlation and phenomenology. It then traces connections between passivity, radical reflection, and indirect ontology in Merleau-Ponty, to show how Meillassoux, contra Merleau-Ponty, takes the activity of thinking for granted and neglects passivity, in ways that lead to ontological confusions and assumptions about being's determinate character. The latter troubles Meillassoux’s ancestrality problem and leads him to overlook a radically contingent being indicated within correlation itself. The final section clarifies and supports this claim via physics, specifically the measurement problem in quantum mechanics—a concrete problem that Meillassoux does not discuss when he broadly invokes mathematics and science to support his position.
