 Yuri Cath suggests that this point can be accommodated by proponents of the Ability Hypothesis, provided they distinguish between Mary’s learning a new proposition and her coming to be in new state of propositional knowledge (2009, 142–143). Specifically, before her release Mary can know that w is a way for someone to imagine red, but only under a theoretical mode of presentation; after her release, she comes to know the same proposition under a practical mode of presentation. She thus comes to be in a new state of propositional knowledge, but without learning any new  propositions.[4]
