V. The Grounding [306]

186. Da-sein

The necessity of the originally grounding question of Da-sein can be unfolded historically:

1. out of ἀλήθεια as the basic character of φύσις;

2. out of the question (compelled by the ego cogito and touched upon by Leibniz and German Idealism) of the double repraesentatio:

a. I represent something—have-there [Da-habe]

b. I represent something-am something; "being-there" ["Da-sein"]. In each case, the "there" is not questioned, just as ἀλήθεια was left unquestioned in the beginning.

And in each case this "there" is only the derived open realm which the correctness of representation must claim for itself and for its own possibility.
