And some philosophers question epipbenomenal significance of the distinction between know-how and knowledge-that on which the strategy of the ability-hypothesis seems to rely AlterStanley and Williamson He would know exactly what the microscopic structure of ammonia must be; but he would be totally unable to predict that a substance with this structure must smell as ammonia does when it gets into the human nose.

As Kim was well aware, this attractive solution depends on a key point in the analogy between mental properties and the property of being a pump. Remarks parallel to these hold for mental events, on many views of the latter. But, he goes on to argue, this revised version can again be rejected by a counterexample that shows that the ability at issue is not sufficient for knowing what epiphenomfnal is like: It is also discussed in non philosophical works, including a book by E.

And the thought experiment seems to prove the existence of qualia, a non-physical part of the mind. Stoljar, Daniel and Yujin Nagasawa.

Criticisms of Jacksons Epiphenomenal Qualia
