 The new dispositionalists disagree. Let us focus on Fara’s diagnosis of the case. The question of whether the agent had the ability to B turns, for Fara, on the question of whether she was disposed to B when she tried to B. Fara claims that she does have such a disposition. The presence of the intervener is, on Fara’s view, like the aforementioned styrofoam packaging in a crystal glass. It masks the disposition of the glass to break when struck, but does not remove that disposition. Similarly, Fara argues, the presence of the intervener masks the agent’s disposition to B when she tries to B, but does not remove that disposition. (There is some disagreement among the new dispositionalists about whether this is a case of finking or masking; see Clarke 2009, 340 for discussion). So, pace Frankfurt, the agent does have the ability to B after all. And so we have, in this case at least, no counterexample to PAP.
