 To sum up, then, Sellars’ attempt to tie existence to temporal notions, when properly relativized, is either a bland re-statement of what special relativity tells us already about simultaneity or an opaque statement about relativized existence. This dilemma confronts any attempt to import pre-relativistic temporal notions into Minkowski spacetime, such as that in §5.7 of Dolev (2007), though Dolev explicitly eschews ontologizing temporal relations. Let us, then, turn to efforts to understand Minkowski spacetime in a different way, efforts that will help clarify the puzzling argument about the Andromedean invasion presented above.
