 It seems, though, that Lewis’s amendment doesn’t help with the problems of maskers and mimickers (Bird 1998; Fara 2005; Choi 2005a). Recall the fragile glass carefully protected with the packing material. The glass, it is thought, is disposed to break when struck. What if it were struck? It would retain all of its molecular structures for a sufficient time. But it would not break because of the masking operation of the packing material. So RCA seems to fail. Similarly, RCA doesn’t avoid the problem of mimickers. The styrofoam dish, if struck, would break by the mimicking operation of the Hater of Styrofoam. Note that, if struck, the dish would retain for a sufficient time an intrinsic property, say, the microstructure responsible for its distinctive sound and, further, this intrinsic property would be a cause of the breaking. The prediction by RCA is therefore that the styrofoam dish is disposed to break when struck, which might be claimed to be counterintuitive.
