Taking its points of departure from Alain Badiou’s readings of Paul Celan, this paper explores Badiou’s philosophical departure from Heidegger and its consequences for the relationship between philosophy and poetry. For Badiou, Celan both takes part in and heralds the closure of a sequence in which, guided by “the question of Being,” poetry constructs “the space of thinking which defines philosophy.” More, in ending this sequence, Celan “completes Heidegger.” The theoretical knot comprised by Badiou, Heidegger and Celan invites us to (...) explore the relationship between poetic language, thought and Being. This paper asserts the centrality of a radical nothingness to any poetic “thought of Being,” and approaches this ontologically efficacious “nothing” via the privilege afforded to “silence” in both Celan’s poetry and Badiou’s imperatives for “the modern poem.” It does this in order to sharpen our understanding of both Badiou’s movement away from Heidegger, and the privileged role Celan plays in this departure. Following an opening discussion concerning the role of silence in Badiou and Celan, this paper then clarifies the relationship between poetic language, silence and Being in Heidegger and Badiou.
