Buren (GA63:nota 1) – existenziell - existenzial

The three occurrences of existenziell   in the present section and in section VI of the Appendix have been translated as “existential.” In its common spelling, i.e., existentiell, this term has the same meaning as the present-day English term “existential” in usages such as “of existential significance.” Heidegger indeed intends existenziell to be understood in this common meaning, but he defines it – in connection with the Kierkegaardian term Existenz   (“existence”) introduced earlier in this section (see also endnote 3) – more precisely as referring to the “ownmost possibility of be-ing” “my own” factical life in the “awhileness of its temporal   particularity” in contrast to an external and reifying approach to human life as an “object” of knowledge. Heidegger later in §4 of Being and Time   contrasts existenziell with existenzial (Macquarrie and Robinson   use “existentiell” and “existential” respectively for these terms), explaining that the former refers to “existing itself’ in its concrete “mineness” (Jemeinigkeit  ) and the latter to the “structures of existence” explicated in hermeneutical ontology. But in the present text   he does not   make this terminological distinction. The term existenzial is not used anywhere. However, Heidegger does, as in Being and Time, employ the noun   Existenzialien (“existentials”) to designate the always temporally particular “categories” or “structures” of “existing (for a while at the particular time)” and “interpreting” which hermeneutical ontology explicates and expresses in “formal   indications.” The term ontisch   (“ontic”) occurs in the previous paragraph and in §7. Ontologisch (“ontological”) occurs throughout the course. These terms appear to have the same meaning that they do later in §4 of Being and Time, where “ontic” refers to “beings” and their actual “be-ing” (or, in the case of human beings, their actual “existing”) and “ontological” refers to the categories or structures of the “being” of these beings which are explicated in ontology. Note that “existence” and “existential” have been reserved for Existenz and existenziell since Heidegger assigns these terms the very specific meanings explained above.
