Heidegger believes that the nothing in non-being-- truth is concealed and as non-ground--must be a thought as belonging to Being. The nothing which belongs to Being is not, of course, the absolute nothing which can only be an ens rationis. Rather, is it a no-thing in relation to beings; that is the Being to which nothing belongs to is not a being, nor a property of beings, nor controllable by any being. Being is the truth of beings only as a ground which is their non-ground. As a twofold negativity, Being is not all controllable; it is the history over which we do not dispose. Being is indeed the truth of beings but in its own truth, it is the uncontrollable and temporal history, the event of Appropriation, Ereignis. In the event of Appropriation, the temporal history and "giving"-character of the truth of Being shows itself.
