  To bring all these points into better view, we need to take a step back and ask the following question. Is the technological mode of revealing ultimately a human doing for which we are responsible? Heidegger's answer is ‘yes and no’. On the one hand, humankind is the active agent of technological thinking, so humankind is not merely a passive element. On the other hand, “the unconcealment itself… is never a human handiwork” (Question Concerning Technology 324). As Heidegger later put it, the “essence of man is framed, claimed and challenged by a power which manifests itself in the essence of technology, a power which man himself does not control.” (Only a God can Save Us; 107, my emphasis). To explicate the latter point, Heidegger introduces the concepts of destining (cf. the earlier notion of ‘destiny’) and enframing. Destining is “what first starts man upon a way of revealing” (Question Concerning Technology 329). As such it is an a priori transcendental structure of human Being and so beyond our control. Human history is a temporally organized kaleidoscope of particular ordainings of destining (see also On the Essence of Truth). Enframing is one such ordaining, the “gathering together of the setting-upon that sets upon man, i.e., challenges him forth, to reveal the actual, in the mode of ordering, as standing-reserve” (Question Concerning Technology 325). This is, of course, a way of unpacking the point (see above) that technology is “a manner of the essential swaying of being” (Contributions 61: 88), that is, of Being's own essential unfolding.
