 The phenomenal concept strategy is criticized by Raffman (1995), Stoljar (2005), Prinz (2007), Chalmers (2007), Ball (2009), Tye (2009), Demircioglu (2013), and Shea (2014). For further works and references see Alter and Walter (2007), Sundström (2011) and Elpidorou (2015). Chalmers offers a “Master Argument” meant to refute any version of the strategy: it is a dilemma based on whether it is conceivable that the complete fundamental physical truth holds yet we possess no phenomenal concepts (having whichever features). The argument is criticized by Papineau (2007), Carruthers and Veillet (2007), and Balog (2012).
