In Heidegger's published writings, the essay "Die Frage nach der Technik" offers the only study devoted to a systematic consideration of modern technology. In the year 1949, Heidegger held four conferences "Im Club zu Bremen" entitled: "the Thing, das Gestell, the Danger, the Turn". The essay which is here to be examined is the reworked version of the conference called "the Gestell" and most probably reproduces the main lines presented in the conference "The Danger", although Heidegger himself affirms that the latter from the fourfold series remained unpublished.¹ However this may be in fact, we will now make ourselves attentive to the published study "Die Frage nach der Technik".²
