Metaphysicians of modality are increasingly critical of possible-worlds talk, and increasingly happy to accept irreducibly modal properties -- and in particular, irreducible dispositions -- in nature.

One central challenge to an anti-Humean view is the context-sensitivity of modal language. I show how that challenge can be met and a systematic modal semantics provided, given an independently plausible metaphysics of dispositional properties or potentialities
