  An alternative response to the argument may be to accept the dependency thesis, but to question whether introspective reflection really does support the claim that the imagistic character of visualising an apple is itself non-neutral with respect to whether the imagined scene contains an apple. It might be held instead that the phenomenology of an episode of visualising does not speak to such matters independently of the question of what suppositions the subject is making in engaging in his imaginative project (see Burge 2005). Alternatively, one might raise a more general scepticism about the reliability of appeals to introspection in supporting claims about the real nature of perceptual experiences (see Spener 2003). Some may hold that since we must allow that hallucinations do not have the sort of phenomenal character that introspective reflection suggests, there is little additional cost in allowing that veridical perceptions also fail to have the phenomenal character that introspective reflection suggests.
