To think Being itself explicitly requires disregarding Being to the extent that it is only grounded and interpreted in terms of beings and for beings as their ground, as in all metaphysics.
Martin HeideggerThe world, in resting upon the earth, strives to surmount it. As self-opening it cannot endure anything closed. The earth, however, as sheltering and concealing, tends always to draw the world into itself and keep it there
Martin Heidegger
