§180 [302-303]

"for the sake of itself," i.e., purely as preservation and stewardship of being, provided what is fundamentally essential is indeed the understanding of being.

179. "Existence"
(Being and Time
, [German] p. 42)

"Existence" ["Existenz"] is at first under the influence of the old concept of existentia: not the "what" but the fact that something is and how it is. But this as παρουσία, presence, extantness (the present).

Now, on the other hand: existence [Existenz] = the full phenomenon of temporality and specifically as ecstatic. Ex-sistere: exposure to beings. But the term already no longer used for some time, because liable to be misinterpreted in the sense of "existential philosophy" ["Existenzphilosophie"].

Da-sein as ex-sistere: insertion into, and standing out into, the openness of beyng. From here alone is determined the "what" (i.e., the "who" and the selfhood) of Da-sein.

Ex-sistence [Ex-sistenz]: for the sake of Da-sein, i.e., for the sake of grounding the truth of beyng.

Ex-sistence [Ex-sistenz] in | the metaphysical sense: presencing, coming to appearance. Ex-sistence [Ex-sistenz] in terms of the historicality of being: steadfast transport into the "there."

180. Beyng and the understanding of being

Out of the understanding of being, abiding in this understanding, which means—since understanding is the projection of the open realm—standing in the openness.

To be related to what (namely, that which is self-concealing) opens up in this openness.

The understanding of being does not make beyng "subjective" or, on the other hand, "objective." It overcomes all "subjectivity" and transposes the human being into the openness of being, i.e., poses the human being as one who is exposed to beings (and exposed in the first place to the truth of beyng).

Contrary to common opinion, however, beyng is the most strange and the self-concealing, and yet it essentially occurs prior to all beings that stand in it. This of course could never be comprehended in terms of the previous concept of the "apriori."
