That's not just any star on the tombstone, that's the sun.
Clearly Heidegger's hidden source are the songs of that great Saturnian, and jazz pianist, Sun Ra. Just check out his album titles: Nothing Is, Lanquidity [that's
Gelassenheit in the jazz vernacular], Strange Celestial Road [AKA
Holzwege], Oblique Parallax [a clear reference to the ontological difference], The Creator of the Universe [
Seyn], Voice of the Eternal Tomorrow [
Ereignis], When Angels Speak of Love [Arendt-Heidegger correspondence], Destination Unknown [
The Self-Assertion of the German University]. Obvious, really.
