Instrumentum signifies that which functions to heap or build up or to arrange. Heidegger here equates it with the noun Einrichtung, translated “contrivance,” which can also mean arrangement, adjustment, furnishing, or equipment. In accordance with his dictum that the true must be sought by way of the correct, Heidegger here anticipates with his identification of technology as an instrumentum and an Einrichtung his later “true” characterization of technology in terms of setting-in-place, ordering, Enframing, and standing-reserve.
