This essay proposes that we turn to James Baldwin’s work to assess the cost of, and think alternatives to, the cultures of traumatization whose proliferation one witnesses in contemporary U.S. academia. Beginning with some recent examples, the essay briefly places these cultures into a genealogy of onto-ethics whose contemporary forms arose with the reconfiguration of diasporic histories in the idioms of psychoanalysis and deconstructive philosophy in 1990s trauma theory. Baldwin speaks to the contemporary moment as he considers the outcome of trauma’s perpetuation in an autobiographical scene from “Notes of a Native Son.” In this scene—which restages Bigger Thomas’s murderous compulsion in Native Son—he warns us against embracing one’s traumatization as a mode of negotiating the world. In foregoing what Sarah Schulman has recently called the “duty of repair,” such traumatized engagement prevents all search for the kind of “commonness” whose early articulation can be found in Aristotle’s query after “the common good” (to koinon agathon). With Baldwin, the present essay suggests the urgency of returning to the question of “the common good”: while mindful of past critiques, which have observed in this concept’s deployment a sleight-of-hand by which hegemonic positions universalize their interests, we should work to actualize the unfinished potential of Aristotle’s idea. Baldwin’s work on diasporic modernity provides an indispensable archive for this effort.
