 Weak representationalism says only that qualitative states necessarily have representational content, which admission is compatible with sensory qualities also necessarily involving features that are ontologically “new” (Block (1990, 1996), Chalmers (1996)). Weak representationalism has been fairly uncontroversial (though it would have been denied by Russell, who showed no sign of thinking that his sense-data represented anything, and by behaviorists and Wittgensteinians who are hostile to the whole idea of mental representation). At the very least, one who rejects it must try to explain why we distinguish between veridical and unveridical experiences; but more recently new opponents such as Campbell (2002), Travis (2004), Noë (2005), Brewer (2006), and Fish (2009) have attempted just that.
