In-der-Blog-sein
Afilmaday has an entry on Deleuze and film that goes on about
mood, or attunement:
[M]ood is the primary attestation to Da-sein's not being its own origin. Prior to and beyond all cognition, mood is an evasive turning away that both discloses and closes off the pure *Da*. Prior to all experience, *Stimmung* makes possible all that is within the world to matter in some way and hence to be experience-able.
I that is linked to how a poem resonates with one, or how a scientific idea strikes one as right, before setting about trying to verify it.
