Pain: the most senseless of things or the most vital of phenomena? This essay aims at a defense of the meaning of pain through an inquiry into the ek-static temporality that structures a being-in-pain. The argument considers the common understanding of pain as a symptom. As the present result of a source of injury that demands a cure, a being-in-pain pictures a movement from something to something else, that is, it pictures the ek-static structure discovered by Aristotle. Furthermore, the argument (...) recalls the Aristotelian apprehension of pain as responsible for the innermost secret of dynamics as such. Pain causes unease and demands change, and hence it opens up a future dimension that marks a beginning of motion and change in general, and of time in particular. When confronted with a pain bound to be chronic, when no change can be expected, time remains. The concluding reading of witness-literature, supports the guiding intuition of pain as a passion in service of things forgotten, in futural light of an eventually new beginning. (shrink)
