technology seeks to unconceal the mystery of the world in general and the mystery of Being in particular. This is why Heidegger contrasts modern technology with poetry, becuase poetry itself merely allows the world to exist in the midst of its mysterious unfolding and unconcealing in the presence of Being and beings. Through seeking to master beings, not only do we not grasp the truth of Being, which is itself the essence of truth (intro metaphysics “truth is the essence of Being”), but we merely make everything else a tool to be wielded and molded to our own use. In the modern technological age, not only do we threaten to control the world through technology, but technology itself threatens to control us (see quote in QCT).
This can be seen as a legitimate outgrowth of Philosophy, which has ceased to be true thinking (see Letter on Humanism). Since Philosophy sought to go away from the mystery of the event of existence and to posit Being into some ethereal realm outside of of any ontical categories, it has given rise to the slow development through Christian thought to the modern turn to the subject seen so pervasively in the thought of Descartes and Kant. This reason is why the question of Being is so important for our modern times to recover anew through the thought of Parmenides and Heraclitus. Far from Philosophy being an evolutionary scheme and a fuller realization of Thought, as in Hegel, though the guise of Philosophy has forgotten the original greatness of the Greeks.
