 A natural representationalist reply is to insist that if the intentional contents would change, so too would the qualitative contents. Block’s nearly explicit argument for denying this is that “qualia” (he fails to distinguish sensory qualities, sense (3), from their higher-order “what it’s like” properties, sense (4)) are narrow, while the intentional contents shift under environmental pressure precisely because they are wide. If sensory qualities are indeed narrow, and all the intentional contents are wide and would shift, then Block’s argument succeeds. (Stalnaker (1996) gives a version of Block’s argument that does not depend on the assumption that the qualities are narrow; Lycan (1996) rebuts it.)
