Joining recent conversations around the work of the British philosopher Gillian Rose, I consider Rose's engagement, not with Hegel, Marx, or Adorno, but with a figure she repeatedly held up as the embodiment of everything she did not want her philosophy to be: Derrida. As a character, I argue, Derrida is crucial to Rose's distinction between the twinned -- enemy -- processes of "aberrated mourning" and "inaugurated mourning." Epitomizing the former, Derrida repeats, for Rose, the halakhic figure of the agunah: the wife deserted by her husband, stuck in a state of waiting for him to return. Through her rejection of the Derridean agunah, I show, Rose articulates her vision of inaugurated mourning -- a vision, she suggests in a footnote, modeled on John Climacus's inaugurated eschatology. I take the footnote seriously, tracking the ways in which Rose's turn to Judaism -- through Derrida -- is bound up with a turn to early Christian theology.
