or: Combinatorics (Rota) as Philosophy (Heidegger) as Geometry (Me)
"Dasein’s full existential structure is constituted by
the 'as-structure' or 'well-joined structure' of the rift-design*…"

Gian-Carlo Rota on Heidegger…
"… The universal as is given various names in Heidegger's writings….
The discovery of the universal as is Heidegger's contribution to philosophy….
The universal 'as' is the surgence of sense in Man, the shepherd of Being.
The disclosure of the primordial as is the end of a search that began with Plato….
This search comes to its conclusion with Heidegger."
… and points as separating rifts—
* rift-design— Definition by Deborah Levitt—
"Rift. The stroke or rending by which a world worlds, opening both the 'old' world and the self-concealing earth to the possibility of a new world. As well as being this stroke, the rift is the site— the furrow or crack— created by the stroke. As the 'rift design' it is the particular characteristics or traits of this furrow."
