KNOWLEDGE, DEFEASIBILITY, AND THE GETTIER PROBLEM

It is natural to assume that since knowledge requires doxastic justification (whatever the exact nature of this), then if doxastic justification is defeasible, as many would assume, then so is knowledge. In the paper I argue that knowledge is defeasible in a way that does not depend on the purported defeasibility of doxastic justification, but rather in a way that relates directly to the famous Gettier Problem. And, though less important in this context, even if doxastic justification is defeasible, this does strictly speaking not make knowledge defeasible.
