 The Navigation question presupposes that we have some modal knowledge, and then investigates how we can move from one kind of modality to another, such as, e.g., from conceptual to metaphysical modality. In other words, it asks how we come to know that some proposition \(p\) is, say, metaphysically necessary, given that we already know that \(p\) is, say, conceptually necessary. While the Navigation question focuses on how we can have a certain kind of modal knowledge given that we already have another kind of modal knowledge, the Access question targets the issue of how we can have modal knowledge in the first place.
