For Derrida, the ‘‘as if’’, as a regulative principle directly appropriated and modified from its Kantian context, becomes the central lynchpin for understanding, not only Derrida's philosophical system as a whole, but also his numerous seemingly enigmatic references to his ‘‘jewishness’’. Through an analysis of the function of the ‘‘as if’’ within the history of thought, from Greek tragedy to the poetry of Wallace Stevens, I hope to show how Derrida can only appropriate his Judaic roots as an act of (...) mourning that seeks to render the lost object as present, ‘‘as if’’ it were incorporated by the subject for whom this act nevertheless remains an impossibility. As Derrida discerns within the poetry of Paul Celan, bringing a sense of presence/presentness to our experiences, and as a confirmation of the subject which the human being struggles to assert, is the poetic task par excellence. It is seemingly also, if Derrida is to be understood on this point, the only option left to a humanity wherein poetry comes to express what religious formulations can no longer justify. (shrink)
