Seeking to contribute to the recent emergence of critical phenomenology by clarifying the relation between ontology and ethics, this article offers a new account of the sources of normativity in the context of Heidegger’s critique of technological enframing (Gestell) and Derrida’s political philosophy. I distinguish three levels of normativity in Heidegger and show how moving between the levels permits the critical deployment of the affirmation (Zusage) in response to being’s address. On this view, not only are humans constitutively claimed by (...) being, but the claim calls for its express hearing and critical elaboration. I then show how Derrida reconceives Heidegger’s normativity by developing a notion of double affirmation that communicates with key concepts from his moral-political work, such as the gift, the advance, and friendship. I conclude by indicating what double affirmation entails for critique today. (shrink)
