Ah, in the paper he says that he&#x27;s not actually talking about free will. That makes it less confusing. But I still think he&#x27;s making much too strong a connection between Knightian unpredictability and free will. I don&#x27;t see any reason at all to think that the former is a necessary condition for the latter, and he doesn&#x27;t really attempt to argue the point. (He promises that he&#x27;s going to argue it in section 2.5, but then section 2.5 ends up only talking about problems of personal identity.)
