 What, then, of the argument from luck? Kane offers a complex response to this problem. First (1996b: 171–72), he counters that with indeterminate events, exact sameness is not defined. If an agent’s effort of will was indeterminate, then it cannot be that in the actual world and in some other possible world she made exactly the same effort. An objection that assumes that such exact sameness is possible, he holds, does not apply to his view. Kane infers from this point that free will requires a form of indeterminism in which there is chance as well as indeterminacy, with the former stemming from the latter. (He calls worlds with such indeterminism “non-Epicurean.”) The chance in an Epicurean world (an indeterministic world without indeterminacy), he implies, would constitute control-diminishing luck.
