 Swimming: Suppose I look at a swimmer’s swimming, and my swimming instructor pointing to the swimmer says to me, “That is a way in which you could swim too”. I believe my instructor and we may suppose that what she said is in fact true. I may thereby come to know a true answer to the question “How could I swim?” However, in the relevant sense, I may not have come to know how to swim. If I took a swimming test, I might still fail it. If thrown in the swimming pool, I might still drown. I do not know how to swim in the relevant sense and yet I do know a true proposition about how to swim.
