Incompatibilism and ambiguity in the practical modalities
Incompatibilists have reasoned that determinism precludes our being able to do anything other than what we actually do. This 'unavoidability argument' transfers a practical modality inability, unavoidability, or power necessity from sufficient conditions to consequences, and cannot be lightly dismissed by compatibilists as it relies on apparently neutral modal principles. Because there are different interpretations of the critical modality, however, doubts arise whether a suitable transfer principle is available for the sort relevant to responsibility. I here set forth and criticize an incompatibilist strategy for sustaining the unavoidability argument despite ambiguity.
