 In an effort to deflect the problem of maskers, Lewis employs what Manley &amp; Wasserman (2008) name the strategy of getting specific. He suggests that we have a choice. We might, on the one hand, say that the protected glass is disposed to break when struck without the packing material; or we might say, instead, that it is disposed to break when struck but this disposition is masked by the packing material. Lewis insinuates that the first option is preferable to the second one. The first option being taken, however, one may well insist that the glass is not disposed to break when struck, which neutralises the problem of maskers. (Note that the strategy of getting specific is basically the same as the one Choi and Gundersen take to deal with the problems of finks, reverse-finks, and mimickers as well as the problem of maskers.)
