Here’s a copy of a my paper. As I suggest at the end, I think this strategy generalizes to other libertarian accounts, although how the argument goes will likely need to be changed depending on the account of how libertarian freedom works with grace – i.e., how the nitty gritty details or mechanics are spelled out. Anselm actually says enough to give us a detailed account of what happens when God changes an agent rather than saying merely that “God influences” human agents. Anyway, enjoy. Or don’t enjoy.
