 Like pragmatic encroachment, contextualism is deeply controversial. Critics have argued that it posits an implausible kind of semantic error in ordinary speakers who do not recognize the putative context-sensitivity—see Schiffer 1996 and Greenough &amp; Kindermann forthcoming—and that it is at odds with plausible theoretical principles involving knowledge—see Hawthorne 2003, Williamson 2005, and Worsnip forthcoming. In addition, some of the arguments that are used to undercut the data motivating pragmatic encroachment are also taken to undermine the case for contextualism; see again Rysiew 2001 and Brown 2006.
