 But, as pointed out by Tye (2000), this does not undermine the Ability Hypothesis. The Ability Hypothesis implies that there is some knowledge that can only be acquired by having experiences of a particular kind and that this knowledge is nothing but knowing-how. This of course does not exclude that there also is propositional knowledge that can be acquired by getting acquainted with kinds of experiences from the first person perspective. The proponent of the Ability Hypothesis only has to insist that, if there is such propositional knowledge, then it need not be acquired on that particular basis but is accessible in other ways as well.
