Near the beginning of chapter 1 of To Follow: the wake of Jacques Derrida (2010), Peggy Kamuf notes “...the dialogic or polylogic form of texts published under Derrida’s name alone,” i.e., bearing a pretense of unifiability (or implicit monology) due to a singularity of the author (presuming a singularity of authorship in being “Derrida”), though there’s “plurivocality in Derrida’s thought,” just as one might expect of a richly imaginative novelist. The singularity of Derrida (the living writer, now long dead) may be trivial relative to the plural interpsychalness of the writing (the living written) in light of inestimable influence (a wake of life, manifold Trace) originally.
But the singularity is not trivial as existing life, trivial only for conceptual tourism that would keep philosophy mirroring one’s presumptions. (One book by Derrida is titled Whose Afraid of Philosophy?, playing on the title of the famous Edward Albee play, I suppose.) The singularity of Derrida’s originality may be primordially plural, proximally interpsychal, yet intrapsychally plural at heart; but not thusly so: The intrapsychalness isn’t a mere gestalt of its interpsychalness; the intrapsychalness isn’t translatable or reducible to an interpsychalness of the Trace (the wake of a life’s time). Instead, the plural psychalness belongs to Derrida singularly, such that any cohering conception of interpsychalness derives from the intrapsychalness so conceiving that (which only Derrida might have done—but would not do, as a matter of principle), a cohering otherwise being merely another’s proffered conception (by a theorist, a philosophical biographer, etc.) of singularity imputed.
I look forward to seeing what Timothy Clark does in The Poetics of Singularity: the counter-culturalist turn in Heidegger, Derrida, Blanchot, and the later Gadamer (2005) one of these days.
