 Even these compatibilist aspirations, however, may be overly optimistic, or at least premature. For in surveying theories of ability we have turned up serious difficulties, for both hypothetical and non-hypothetical approaches, which do not appear to turn on issues about determinism. So it may be that the best hope for progress is to pursue theories of ability while setting to one side the problems raised in the free will debates. For given the difficulties posed by abilities, and given the significance of theories of ability for areas of philosophy quite removed from the free will debates, there is something to be said for pursuing a theory of ability while embracing, if only temporarily, a certain quietism about the puzzles that determinism may pose.
