The possibility of an early philosophy of technique in Heidegger is discussed, starting from the phenomenology of the tool and the organ that the German thinker develops in Being and Time and in The Fundamental Concepts of Metaphysics, respectively. Such meditation, it is conjectured, would constitute a propaedeutic of his late philosophy of technique. It concludes, on the one hand, with an observation on the metaphysical limits that this early conception of technique would impose on his later philosophy, and on the other, with a question not answered by Heidegger, which confronts Dasein with his technological project.
