 Despite the apparent force, however, it is not universally agreed that these examples undermine SCA. Some philosophers insist that SCA, when properly understood, is not susceptible at all to the alleged counterexamples, whilst some others maintain that they do refute SCA but they can be avoided by suitable sophistications of it. The first position is supported by Choi (2006, 2008) and Gundersen (2002), who challenge the assumption about what dispositions an object possesses in each of the alleged counterexamples. They emphasise that when the glass is protected by the packing material it is no longer disposed to break when struck; rather, it is disposed to break when struck in the absence of the packing material. This is in line with SCA since the glass would indeed break if struck in the absence of the packing material although it wouldn’t break if struck under its current conditions—mutatis mutandis for the example of reverse-cycle finks. Similarly, Choi suggests that when the styrofoam dish is in the neighborhood of the Hater of Styrofoam, it is indeed disposed to break when struck; it is not disposed to break when struck in the absence of the Hater of Styrofoam. This suggestion is consistent with SCA since the dish wouldn’t break if struck in the absence of the Hater of Styrofoam although it would break if struck under its current conditions—mutatis mutandis for the example of finks.
