ABSTRACT We argue that S is in a position to know that p iff S can know that p. Thus, what makes position‐to‐know‐ascriptions true is just a special case of what makes ability‐ascriptions true: compossibility. The novelty of our compossibility theory of epistemic modality lies in its subsuming epistemic modality under agentive modality, the modality characterizing what agents can do.
