 Naturally, then, much subsequent critical discussion has focused on Martin’s negative epistemic conception of hallucination. Further discussion and development of Martin’s approach is to be found in Nudds (2009, 2013) and Soteriou (2014: Chapter 6). For criticism of Martin’s approach see Hawthorne and Kovakovich (2006), Farkas (2006), Sturgeon (2008), Siegel (2004, 2008), and Robinson (2013). See Burge (2005) for a general and polemical attack on disjunctivism. For more on disjunctivism, see Haddock and Macpherson (eds.) (2008), Byrne and Logue (eds.) (2009), Macpherson and Platchias (eds.) (2013) and the entry on  the disjunctive theory of perception.
