Nagel takes a slightly different approach. Levine argues that even these refined theories do not account for the specific intimite way in which the thinker is related to the referents of phenomenal concepts.

Jackson himself went on to reject epiphenomenalism, and dualism altogether. Sign in to use this feature. Although he finds this a perfectly good argument, he realizes that it will not persuade everyone 1.

And the thought experiment seems to prove the existence of qualia, a non-physical part of the mind. In light of such considerations, Churchland distinguishes between two senses of knowing, “knowing how” and “knowing that”, where knowing how refers to abilities and knowing that refers to knowledge of facts. Several objections to Jackson have been raised on the grounds that Mary does not gain new factual knowledge when she leaves the room, but rather a new ability.

A similar example is used for the same purpose and discussed in more detail by Raymont If all physical facts can be known under some physical conceptualization, then a person who has complete physical knowledge about a topic knows all the relevant physical facts. Others deny even the weaker version V1 and claim that Mary does not gain any new propositional knowledge no new knowledge about something that is the case, no factual knowledge. Many take it to be obvious that a person cannot know that she now has a blue experience unless her blue experience plays a prominent causal role in the formation of her belief at issue.

Chalmers considers responses along the lines of the “ability hypothesis” objection described above to be the most promising objections, but unsuccessful: Nagel on the other hand seems to be arguing that we cannot generalize from what our experience is like to what bat experience is like because they are too different from us a.

According to the Ability Hypothesis most prominently defended in Lewisand in Nemirow,Mary does not acquire any new propositional knowledge after release no knowledge about something that is the case, no factual knowledgebut only a bundle of abilities like the ability to jckson, remember and recognize colors or epipenomenal experiences.
