The common view of technology is instrumental: it is a neutral means, good or bad according to its use. In the text he published in 1954, Martin Heidegger calls this view 'correct but not true' — the description is not wrong, but it does not show what technology is.

His argument is that technology is a mode of disclosure (aletheia); it makes the world appear to us in a particular way. In older technique — a windmill, a peasant's field — nature is left to its own rhythm and what is taken is not stockpiled. Modern technology carries a challenging (Herausfordern) toward nature: from the moment the hydroelectric plant is built, the Rhine is no longer a river but an energy source; the forest is a stock of timber, and people become 'human resources'. Heidegger calls this way of seeing *Gestell*, enframing. The danger lies not in machines but in this frame becoming the only way of seeing: when everything appears as calculable resource, other modes of disclosure — art, thinking — close off.

The text is among the founding works of the philosophy of technology; Marcuse, Ellul, Borgmann and today's critiques of the data economy and artificial intelligence use this framework or argue with it. It also carries Heidegger's most contested aspect: his membership of the Nazi Party and his silence about it after the war remain a problem that shapes how his thought is read, and the publication of the Black Notebooks in 2014 reopened the argument. Whether a text's claims can be assessed independently of its author's historical position is itself a methodological question in reading philosophy.
