Keith deRose, "Contextualism and Knowledge Attributions"

Defends contextualism about knowledge ascriptions against the criticism that it seems absurd to say that one can truly say in context 1 that one knows that one saw zebras at the zoo, and then in context 2 truly say that one didn't (doesn't?) know that one saw zebras at the zoo by insisting that knowledge ascriptions function like indexicals. One can truly say, in context 1, that one knows, and then truly say in context 2 that one didn't know without contradicting oneself.

Comment: This seems more plausible when there IS a difference in some kind of indexical element, like the tense---it sounds better (though not great) to say, "I knew then that that I saw a zebra" and "Now I don't know whether I saw a zebra or just a painted mule".
