In public discourse trauma is predominantly framed as an overwhelming event undergone by the individual. In this article I first provide a brief genealogy to trace the emergence of what is now the dominant temporal framework of psychological catastrophe. I supplement this evental nosology with a durational consideration of trauma by drawing on the works of Henri Bergson and his articulation of duration, memory, and lived experience. Durational trauma accommodates liminal and ongoing experiences of the catastrophic that are equally devastating (...) to the paradigmatic exemplars of PTSD. This alternate account entails different modalities of reparation and responsibility to the systemic traumatization of others. For this I draw on Levinas and his intersubjective ethics drawing out the relevancy his work has for this concept of durational trauma. Levinas’s emphasis on expiation avoids the reification of the trauma of the other as spectacle and draws into focus one’s own participation in the circulation and continuation of ongoing traumatic networks. This contributes to the emergent alchemy of reading Bergson and Levinas together, but likewise, to philosophy of trauma and the ethical responsibility and temporality of ongoing systemic harm.
