 A second family of arguments against free will contend that, in one way or another, nondeterministic theories of freedom entail either that agents lack control over their choices or that the choices cannot be adequately explained. These arguments are variously called the ‘Mind’, ‘Rollback’, or ‘Luck’ argument, with the latter admitting of several versions. (For statements of such arguments, see van Inwagen 1983, ch. 4; 2000; Haji 2001; Mele 2006; Shabo 2011, 2013, 2020; Coffman 2015). We note that some philosophers advance such arguments not as parts of a general case against free will, but merely as showing the inadequacy of specific accounts of free will [see, e.g., Griffith 2010].) They each describe imagined cases—individual cases, or comparison of intra- or inter-world duplicate antecedent conditions followed by diverging outcomes—designed to elicit the judgment that the occurrence of a choice that had remained unsettled given all prior causal factors can only be a ‘matter of chance’, ‘random’, or ‘a matter of luck’. Such terms have been imported from other contexts and have come to function as quasi-technical, unanalyzed concepts in these debates, and it is perhaps more helpful to avoid such proxies and to conduct the debates directly in terms of the metaphysical notion of control and epistemic notion of explanation. Where the arguments question whether an undetermined agent can exercise appropriate control over the choice he makes, proponents of nondeterministic theories often reply that control is not exercised prior to, but at the time of the choice—in the very act of bringing it about (see, e.g., Clarke 2005 and O’Connor 2007). Where the arguments question whether undetermined choices can be adequately explained, the reply often consists in identifying a form of explanation other than the form demanded by the critic—a ‘noncontrastive’ explanation, perhaps, rather than a ‘contrastive’ explanation, or a species of contrastive explanation consistent with indeterminism (see, e.g., Kane 1999; Clarke, 2003, ch. 8; and Franklin 2011a; 2018, ch. 5).
