Dynamic Modality in a Possible Worlds Framework
Abilities – no doubt – have a modal nature, but how to spell out this modal nature is up to debate. In this essay, one approach is of special interest. It could be called the restricted possibility approach to ability.

In light of (ii), all states are deemed “possible”. Semantics operate in two...

First, I present the neo-Humean picture of modality, and explain why those who accept it deny a common sense view of modality. Second, I present what I take to be the most pressing objection to the neo-Humean account, one that, I argue, applies equally well to any...
