 Another way of putting the worry is this: since attributions of responsibility are usually anchored in some morally relevant feature of the agent to which awareness contributes, such as choice or good/ill will (Amaya &amp; Doris 2015: 254), an account of responsibility for unwitting wrongdoing in which neither choice nor the agent’s quality of will are implicated runs the risk of appearing ad hoc (King 2009: 587). So the challenge for capacitarians is to show that their account isn’t ad hoc and, at the same time, to provide a “morally plausible desert basis for blame” in cases of unwitting wrongdoing (Moore &amp; Hurd 2011: 160).
