Heidegger glimpses the problem. Forgetting cannot be understood as mere omission-it is not always a lapsus. Though he tries to outline a certain structural hypothesis ("forgetting should not be understood as a merely human act or departure"), he attempts to de-psychologize forgetting ("it is not the umbrella left behind by the philosophy professor, it belongs to the 'thing of Being'").
But the aforementioned forgetting of the being, decisive in interpreting the history of metaphysics, has not been sufficiently developed through its specific logic. From the status of that forgetting the conditions of the "overcoming of metaphysics," its end and the possible corresponding twist, may be fixed. Then forgetting is "the promise of a discovery," while the question of forgetting in Heidegger reveals the thinker as a perceptive commentator on this yet unknown experience: psychoanalysis.
