 As noted earlier, some philosophers deny that experience is transparent. They claim that introspection does not show that experiences lack introspectible, intrinsic, nonrepresentational properties. Further, they insist that representationalism encounters decisive objections. These objections may be seen as making up one pillar in the main foundation for the view that experiences have qualia, conceived of now as intrinsic, nonrepresentational properties. The second pillar consists in what is sometimes called “the common kind assumption”, namely that veridical and hallucinatory experiences sometimes share the same phenomenal character (have the same qualia). This assumption is accepted by all the advocates of the views discussed so far but it is denied by advocates of relational theories of qualia (see section 9).
