 Yet, it is unclear that even this response works. Consider a variant of the previous scenario, where Mary is a skilled swimmer who is one day affected by memory loss and so forgets how she is able to swim (Glick 2015). Nothing has changed in Mary’s physical state: she is still able to swim but she just has forgotten how she is able to swim. Suppose she is told, by looking at a recording of her swimming the day before, that that is how she can in fact swim given her current physical state. She might come to know how she is in fact able to swim (just like that!). Yet, she would still fail to know how to swim in the relevant sense and still drown if thrown into the pool.
