The fascination of today's would-be "atheistic" French philosophers like Žižek and Badiou with the singularity of the crucified Christ is not accidental. So much of postmodern thought is not merely an "overcoming of metaphysics" and ontology, but a quest to penetrate to the singularity that is neither logical, ethical, nor ontological, but (as Heidegger would put it) the "origin" of the intelligibly determinative. Beginning with Heidegger himself, whom Derrida never really understood and who inaugurated the quest itself, we find a struggling to find some kind of "name" for this origin. Heidegger calls it the "Being" that can "be" only by crossing it out.You only cross it out to indicate to the reader that you don't mean "being" as all the others explain it, but that you mean beyng.
