already the consequence of a more original Da-sein which is gathered into the encompassing refusal, i.e., into the essential occurrence of beyng. Expressed in the still-surviving language of metaphysics, this says: refusal as the essential occurrence of beyng is the highest actuality of the highest possibility as possibility and thus is the first necessity. Da-sein is the grounding of the truth of this simplest fissure.
170. Da-sein
not something that could simply be found as given with some objectively present human being; rather, the ground of the truth of beyng, a ground necessitated by the basic experience of beyng as event. Through this ground (and its grounding), the human being is transformed from the ground up.
Only now does the animal rationale collapse, though we are in the act of relapsing into it precipitously whenever we know neither the first beginning and its end nor the necessity of the other beginning.
The collapse of the former "human being" possible only on the basis of an originary truth of beyng.
171. Da-sein4
the ground of future human being, a ground that essentially occurs in the grounding.
Da-sein—care.
The human being on this ground of Da-sein:
1. the seeker of beyng (event)
2. the preserver of the truth of being
3. the steward of the stillness of the passing by of the last god.
Stillness and origin of the word.
At first, however, the grounding of Da-sein is in itself transitional and tentative—care, temporality [Zeitlichkeit]; temporality grounded in primordial temporality [Temporalität]: as the truth of beyng. Da-sein is related to truth as the openness of self-concealing, begun by the understanding of being. Projecting the open realm for being. Da-sein as projection of the truth of beyng (the "there").
