  In his 1953 piece The Question Concerning Technology, Heidegger begins with the everyday account of technology according to which technology is the vast array of instruments, machines, artefacts and devices that we human beings invent, build, and then exploit. On this view technology is basically a tool that we control. Heidegger claims that this everyday account is, in a sense, correct, but it provides only a limited “instrumental and anthropological definition” of technology (Question Concerning Technology 312). It depicts technology as a means to an end (instrumental) and as a product of human activity (anthropological). What needs to be exposed and interrogated, however, is something that is passed over by the everyday account, namely the essence of technology. To bring this into view, Heidegger reinterprets his earlier notion of intelligibility in terms of the concept of a clearing. A clearing is a region of Being in which things are revealed as mattering in some specific way or another. To identify the essence of technology is to lay bare technology as a clearing, that is, to describe a technological mode of Being. As Heidegger puts it in the Contributions (61: 88), “[i]n the context of the being-question, this word [machination, technology] does not name a human comportment but a manner of the essential swaying of being”.
