 Lycan (1996) argues against the Ability Hypothesis and for the view that Mary acquires new knowledge-that after release by claiming that “S knows what it is like to see blue” means something like “S knows that it is like Q to see blue” where Q names the phenomenal quality at issue. It has been objected by Tye (1995) that the use of the qualia name “Q” within a propositional attitude context creates the well-known problems: Replacing “Q” by another name “R” for the same quale may change the truth value of the belief ascription. A proponent of Lycan’s view could however respond along the following lines: In the case of qualia names within belief contexts it does not matter which name is used to refer to the quale at issue as long as the belief is meant in the sense of a phenomenal belief ascription. “S believes that it is like Q to see blue” means, on the phenomenal reading, that S has the relevant belief about Q under a phenomenal concept of Q. Under the assumption that it is impossible to have two different phenomenal concepts of one and the same quale, the objection is met: As long as two qualia names Q and R refer to the same quale, replacing Q by R in an ascription of phenomenal belief cannot change the truth value of the belief ascription.
