"[T]he tenor of Derridian philosophy shares with Heidegger’s a dangerous proclivity towards the bombastic translations of problems of being and knowledge into strident moral dilemmas. Like the cosmic drama of Being repressed by being in Heidegger, Derrida’s protests against phonocentrism sound more like lay sermonizing than genuine analytical argument. Those manichean dichotomies -- Being verses being, ‘writing’ verses phoné -- betray a religious pattern of thought that leaves Derrida -- for all his reticence regarding eschatology -- infinitely closer to the prophet Levinas than to the cool-headed practice of philosophy as analysis. Once removed from this original ‘theological’ and mystical framework, the Derridian ontology of absence makes for an irrationalist philosophy, as was the case with Heidegger. Hence the blatent non-sequiturs. […] Logical jumps are dictated by by the obsessional nature of dramatic philosophy, that is, where the glamour of a manichean grand-guignol (Presence the goodie versus absence the goodie) is substituted for analytics rigour."
