The first chapter explores Jacques Derrida’s rich reworking of the Kantian regulative principle of the as if in order to point toward certain potential movements of the as such in the poetry of Wallace Stevens, Adrienne Rich, and Paul Celan, as well as the various mystical traditions which Derrida himself took up on occasion. By taking this precise path and yet staying open to Derrida’s critique of any possible presentation as such beyond the as if, this chapter shows how Derrida’s work ultimately also points toward an encounter with the O/other as such, beyond the as if, though within language, very much within its failures—which is, in the end, the only real way to fully respect the encounter at all. In such fashion, an ethical imperative appears within the event of encounter, one that does not seek to reduce the singularity of the O/other’s presence before us to a regulative ideal as if to go beyond what has been (re)presented to us, but rather that which embraces what cannot be represented, bringing philosophy, politics, and religion to the threshold of a mystical-ethical imperative that we must take very seriously.
