 In advancing a compatibilist thesis, Vihvelin speaks of the ability to do otherwise (and especially choose otherwise) in terms of a bundle of dispositions (2004, p. 429). Likewise, Fara proposes a dispositional analysis of the ability to do otherwise. And Smith speaks of the rational capacities to believe and desire otherwise (and so, presumably, do otherwise) in terms of a “raft of possibilities” (2003, p.27). For Fara, Vihvelin, and Smith, we assess claims about the disposition constitutive of the ability to do otherwise, or the dispositions in the bundle, or the possibilities in the raft, by attending to the intrinsic properties of an agent in virtue of which she acts when she tries (Fara 2008, p.861), or the causal bases of the pertinent dispositions (Vihvelin 2004, p. 436), or the underlying structure of a rational capacity (Smith, p. 29). How so?  Fara does not say, though it seems likely he would agree to something like the proposals offered by Vihvelin and Smith. According to them, we hold fixed the relevant causal base or underlying structure of an agent’s disposition to, say, wave hello to a friend, or tell the truth under interrogation, and we consider various counterfactual conditions in which that causal base or underlying structure operates unimpaired. Does the agent in an appropriately rich range of such counterfactual conditions wave hello or tell the truth? If she does, then even if in the actual world she does not wave hello or tell the truth, she was able to do so. She had at the time of action the pertinent agential abilities or capacities. And this is true even if that world is determined (see, e.g., Vihvelin 2004, 437). Why?  Because there is no basis for contending that when we test the relevant dispositions at other possible worlds, we have to restrict the worlds to ones in which we hold fixed the past and the laws. Note how the problems with the classical compatibilists’ counterfactual analysis are circumvented. If we are attending to the causal base of the relevant dispositions, we can easily see how Danielle’s relevant causal base is ill-equipped for picking up blond haired dogs.
