 We have three comments to add on Lewis’s responses. The first comment is that Lewis denies that the problems of maskers and mimickers throw light on the analysis of dispositionality that philosophers intend to attain by the conditional analysis of dispositions. On his view, they touch upon merely the pragmatic issue of what specifications are built into the stimulus conditions and manifestations corresponding to a given dispositional concept. This is disputed by Choi (2008). Secondly, there is a noticeable tension between Lewis’s criticism of SCA and his defence of RCA from the problems of maskers and mimickers. We have seen earlier that Lewis tries to add force to the problem of finks by assuming IDT. But this assumption seems to undermine his own defence of RCA from the problems of maskers and mimickers. Lewis’s response to the problem of maskers is that the protected glass is disposed to break when struck without the packing material, which explains away the intuition that it is fragile; and that this opens the door for insisting that it is in fact not disposed to break when struck. But this move seems to be on a collision course with IDT because an unprotected intrinsic duplicate of the glass is undoubtedly disposed to break when struck. This illustrates the tension between Lewis’s treatments of the problems of finks and maskers—and mutatis mutandis for the problems of mimickers (see Choi 2009 for discussion).
