 A further question is why, on the Heideggerian framework, the state of projecting possibilities does not count as epistemic or truth-evaluable, even if we allow that it is also in some sense ontological. After all, the possibilities that we project onto the world might not be genuine or grounded in reality. As Grimm (2008) notes, someone might think that apparently solid things (like baseballs) could not possibly pass through other apparently solid things (like tables), but learning about quantum tunneling might call this into question, and transform one’s sense of possibility. There thus seem to be facts about the possibilities that the world affords, and it seems like a mind could either track these facts accurately, or not. But this appears to be a topic of interest not just to ontologists or metaphysicians, but to epistemologists as well (cf. Westphal 1999).
