The Absent Foundation : Heidegger on the Rationality of Being

For Heidegger, the fundamental “rationality” of Western metaphysics lies in the fact that its “leading question” concerning beings as beings constantly refers back to the question concerning the ground (arche, ratio, Grund) of beings. Whereas metaphysics has sought to ground beings in ideal beingness, Heidegger attempts to think beingness as itself based on the withdrawing “background” dimension of no-thing-ness that grounds finite presence by differing from it. In Heidegger’s earlier work, the structure of this “grounding” is considered in terms of Dasein’s temporal transcendence; later, it is rearticulated through the fourfold dimensionality of meaningfulness (Geviert), converging in a concrete thing.Peer reviewe
