The majority of authors in the complicity literature claim that causal accounts of complicity are inadequate because they fail to handle cases of causal overdetermination (Kutz, 2000, 2007, 2020; Lawson, 2013; Driver, 2015a, b; Bazargan-Forward, 2013, 2017, 2022; Mellema, 2016; Aragon and Jaggar, 2018; Williams 2019; Bennett, 2021; Donohue, 2021; Knowles, 2021). However, it has recently been argued that causal accounts can handle such cases (Lepora and Goodin, 2013; Petterson, 2013; Jensen, 2020). In this paper I scrutinize these defenses. I (...) argue while they make some progress towards overcoming the standard overdetermination challenge, they are not fully satisfactory. More importantly, I present a novel challenge raised by cases of overdetermination—the explanatory challenge. I argue that, not only do these recent defenses not overcome this challenge, it is unlikely that any causal account can overcome it. Finally, I suggest that since causal accounts of complicity are inadequate, pluralism about complicity must be correct, because we cannot fully dispense with causation from our understanding of complicity.
