 At least one compatibilist has tried embracing environment-dependent syntax, though he concedes it is an uncomfortable view (Ludlow 2003; 2011). At the least, such a stance would seem ad hoc (Besson 2012). Others question the “supervenience principle” in the argument, viz., that a difference in form necessitates a difference in internal state (Corbí 1998, Brown 1999, Korman 2006, Parent 2015a, 2017, ch. 4). Further argument has been offered for this principle (Boghossian 1998), yet such arguments may beg the question by presupposing a Chomskian, internalist notion of logical form (Parent 2015a, 2017, ch. 4).
