 Others (van Inwagen 2000; Mele 2006) have argued that even if agent-causation is possible, it would not solve the problem of transforming an undetermined event into one which is in our control in the way that our free choices must be. And others have argued that if agent-causation is possible, it is possible at deterministic as well as non-deterministic worlds (Markosian 1999; Nelkin 2011; Franklin 2016).
