 Most commentators on examples like this agree that the agent is both morally responsible for her act and acts freely in whatever sense of freedom they endorse. They differ on whether she can do otherwise at the time of her act. Determinists generally interpret the case as one in which she exercises compatibilist free will and has no alternate possibilities. Most libertarians interpret it as one in which she exercises libertarian free will and has alternate possibilities, contrary to appearances. As mentioned above, some philosophers have interpreted it as a case in which she exercises libertarian free will but does not have alternate possibilities. If Frankfurt cases can be successfully interpreted in this third way, then they can be used to show the compatibility of infallible foreknowledge and libertarian freedom. Hunt (1999a) argues that this is essentially the solution put forward by Augustine in On Free Choice of the Will III.1–4, though Augustine’s own considered position on free will was not libertarian.
