should be able to lay hold of the saving power immediately and without preparation. Therefore we must consider now, in advance, in what respect the saving power does most profoundly take root and thence thrive even in that wherein the extreme danger lies, in the hdlding sway of Enframing. In order to consider this, it is necessary, as a last step upon our way, to look with yet clearer eyes into the danger. Accordingly, we must once more question concerning technology. For we have said that in technology's essence roots and thrives the saving power.
But how shall we behold the saving power in the essence of technology so long as we do not consider in what sense of "essence" it is that Enframing is actually the essence of technology?
Thus far we have understood "essence" in its current meaning. In the academic language of philosophy, "essence" means what something is; in Latin, quid. Quidditas, whatness, provides the answer to the question concerning essence. For example, what pertains to all kinds of trees-oaks, beeches, birches, firs-is the same "treeness." Under this inclusive genus-the "universal"fall all real and possible trees. Is then the essence of technology, Enframing, the common genus for everything technological? If that were the case then the stearn turbine, the radio transmitter, and the cyclotron would each be an Enframing. But the word "En framing" does not mean here a tool or any kind of apparatus. Still less does it mean the general concept of such resources. The machines and apparatus are no more cases and kinds of Enframing than are the man at the switchboard and the engineer in the drafting room . .E ach of these in its own way indeed belongs as stockpart, available resource, or executer, within Enframing ; but Enframing is never the essence of technology in the sense of a genus. Enframing is a way of revealing having the character of destining, namely, the way that challenges forth. The revealing that brings forth (poiesis) is also a way that has the character of destining. But these ways are not kinds that, arrayed beside one another, fall under the concept of revealing. Revealing is that destining which, ever suddenly and inexplicably to all thinking, apportions itself into the revealing that brings forth and that also challenges, and which allots itself to man. The challenging revealing
