In a new book by Thomas de Zengotita, Mediated, we find this passage, on Bill Cinton's State of the Union speech following the Monica revelations:

But, as is the way of ontology, that most fundamental of questions went unarticulated, and so assumed what Heidegger would call its "grounding significance." How's that for an angle? The Monica State of the Union as a Heideggerian moment of decision. It works for me.

I don't recall Heidegger anywhere calling anything any thing's "grounding significance", so for an angle I would call that one obtuse.  ¶ 1:23 PM
