“At this point we come across one of Heidegger’s most troubling formulations, that of the oblivion of being (Seinsvergessenheit), by which he refers to the forgetting of the forgetting of being, the withdrawal of its withdrawal, such that even the traces of being’s concealment have over time become lost and thus its question has become forgotten. On the surface this seems to be an inevitable consequence of his thinking of alētheia, but if this forgetting or withdrawal – and we must emphasize both insofar as each are translations of lēthē – is itself forgotten or withdrawn, then this doesn’t mean that it has simply vanished, for this would be to misread what takes place in forgetting. What is forgotten may not be available to be recalled but this lack punctuates thought and thus leaves a mark of forgetting which itself cannot be forgotten, even if it cannot be recalled.”
