Felix Ó Murchadha's The Time of Revolution: Kairos and Chronos in Heidegger
Something indeed "remains inappropriable for human poiesis". Works of art are "a free relation, a free response" to such disclosure and withdrawal in the history of being, and they show or sound "the possibility of . . . a new order of experience". Their 'actuality' in effect serves or 'promises' the resilience of possibility for human action, now more forcibly under the rubric of occurrence. The resulting challenge for revolutionary action, however, is to 'think' in such a way that does not lose the trace of kairos in the chronos that ensues.
